单片机英文文献资料及翻译单片机(英文：Microcontroller)Microcontroller is a small computer on a single integrated circuit that contains a processor core, memory, and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.A microcontroller's processor core is typically a small, low-power computer dedicated to controlling the operation of the device in which it is embedded. It is often designed to provide efficient and reliable control of simple and repetitive tasks, such as switching on and off lights, or monitoring temperature or pressure sensors.MEMORYMicrocontrollers typically have a limited amount of memory, divided into program memory and data memory. The program memory is where the software that controls the device is stored, and is often a type of Read-Only Memory (ROM). The data memory, on the other hand, is used to store data that is used by the program, and is often volatile, meaning that it loses its contents when power is removed.INPUT/OUTPUTMicrocontrollers typically have a number of programmable input/output (I/O) pins that can be used to interface with external sensors, switches, actuators, and other devices. These pins can be programmed to perform specific functions,such as reading a sensor value, controlling a motor, or generating a signal. Many microcontrollers also support communication protocols like serial, parallel, and USB, allowing them to interface with other devices, including other microcontrollers, computers, and smartphones.APPLICATIONSMicrocontrollers are widely used in a variety of applications, including:- Home automation systems- Automotive electronics- Medical devices- Industrial control systems- Consumer electronics- RoboticsCONCLUSIONIn conclusion, microcontrollers are powerful and versatile devices that have become an essential component in many embedded systems. With their small size, low power consumption, and high level of integration, microcontrollers offer an effective and cost-efficient solution for controlling a wide range of devices and applications.。

Structure and function of the MCS-51 seriesStructure and function of the MCS-51 series one-chip computer MCS-51 is a name of a piece of one-chip computer series which Intel Company produces. This company introduced 8 top-grade one-chip computers of MCS-51 series in 1980 after introducing 8 one-chip computers of MCS-48 series in 1976. It belong to a lot of kinds this line of one-chip computer the chips have,such as 8051, 8031, 8751, 80C51BH, 80C31BH,etc., their basic composition, basic performance and instruction system are all the same. 8051 daily representatives- 51 serial one-chip computers .An one-chip computer system is made up of several following parts: ( 1) One microprocessor of 8 (CPU). ( 2) At slice data memory RAM (128B/256B),it use not depositting not can reading /data that write, such as result not middle of operation, final result and data wanted to show, etc. ( 3) Procedure memory ROM/EPROM (4KB/8KB ), is used to preserve the procedure , some initial data and form in slice. But does not take ROM/EPROM within some one-chip computers, such as 8031 , 8032, 80C ,etc.. ( 4) Four 8 run side by side I/O interface P0 four P3, each mouth can use as introduction , may use as exporting too. ( 5) Two timer / counter, each timer / counter may set up and count in the way, used to count to the external incident, can set up into a timing way too, and can according to count or result of timing realize the control of the computer. ( 6) Five cut off cutting off the control system of the source . ( 7) One all duplexing serial I/O mouth of UART (universal asynchronous receiver/transmitter (UART) ), is it realize one-chip computer or one-chip computer and serial communication of computer to use for. ( 8) Stretch oscillator and clock produce circuit, quartz crystal finely tune electric capacity need outer. Allow oscillation frequency as 12 megahertas now at most. Every the above-mentioned part was joined through the inside data bus .Among them, CPU is a core of the one-chip computer, it is the control of the computer and command centre, made up of such parts as arithmetic unit and controller , etc.. The arithmetic unit can carry on 8 persons of arithmetic operation and unit ALU of logic operation while including one, the 1 storing device temporarilies of 8, storing device 2 temporarily, 8's accumulationdevice ACC, register B and procedure state register PSW, etc. Person who accumulate ACC count by 2 input ends entered of checking etc. temporarily as one operation often, come from person who store 1 operation is it is it make operation to go on to count temporarily , operation result and loopback ACC with another one. In addition, ACC is often regarded as the transfer station of data transmission on 8051 inside . The same as general microprocessor, it is the busiest register. Help remembering that agreeing with A expresses in the order. The controller includes the procedure counter , the order is depositted, the order decipher, the oscillator and timing circuit, etc. The procedure counter is made up of counter of 8 for two, amounts to 16. It is a byte address counter of the procedure in fact, the content is the next IA that will carried out in PC. The content which changes it can change the direction that the procedure carries out . Shake the circuit in 8051 one-chip computers, only need outer quartz crystal and frequency to finely tune the electric capacity, its frequency range is its 12MHZ of 1.2MHZ. This pulse signal, as 8051 basic beats of working, namely the minimum unit of time. 8051 is the same as other computers, the work in harmony under the control of the basic beat, just like an orchestra according to the beat play that is commanded.There are ROM (procedure memory , can only read ) and RAM in 8051 slices (data memory, can is it can write ) two to read, they have each independent memory address space, dispose way to be the same with general memory of computer. Procedure 8051 memory and 8751 slice procedure memory capacity 4KB, address begin from 0000H, used for preserving the procedure and form constant. Data 8051- 8751 8031 of memory data memory 128B, address false 00FH, use for middle result to deposit operation, the data are stored temporarily and the data are buffered etc.. In RAM of this 128B, there is unit of 32 byteses that can be appointed as the job register, this and general microprocessor is different, 8051 slice RAM and job register rank one formation the same to arrange the location. It is not very the same that the memory of MCS-51 series one-chip computer and general computer disposes the way in addition. General computer for first address space, ROM and RAM can arrange in different space within the range of this address at will, namely the addresses of ROMand RAM, with distributing different address space in a formation. While visiting the memory, corresponding and only an address Memory unit, can ROM, it can be RAM too, and by visiting the order similarly. This kind of memory structure is called the structure of Princeton. 8051 memories are divided into procedure memory space and data memory space on the physics structure, there are four memory spaces in all: The procedure stores in one and data memory space outside data memory and one in procedure memory space and one outside one, the structure forms of this kind of procedure device and data memory separated form data memory, called Harvard structure. But use the angle from users, 8051 memory address space is divided into three kinds: (1) In the slice, arrange blocks of FFFFH , 0000H of location , in unison outside the slice (use 16 addresses). (2) The data memory address space outside one of 64KB, the address is arranged from 0000H 64KB FFFFH (with 16 addresses ) too to the location. (3) Data memory address space of 256B (use 8 addresses). Three above-mentioned memory space addresses overlap, for distinguishing and designing the order symbol of different data transmission in the instruction system of 8051: CPU visit slice, ROM order spend MOVC , visit block RAM order uses MOVX outside the slice, RAM order uses MOV to visit in slice.8051 one-chip computer have four 8 walk abreast I/O port, call P0, P1, P2 and P3. Each port is 8 accurate two-way mouths, accounts for 32 pins altogether. Every one I/O line can be used as introduction and exported independently. Each port includes a latch (namely special function register ), one exports the driver and a introduction buffer . Make data can latch when outputting, data can buffer when making introduction , but four function of passway these self-same. four port these may serve as accurate two-way mouth of I/O in common use. Expand among the system of memory outside having slice, P2 mouth see high 8 address off; P0 mouth is a two-way bus, send the introduction of 8 low addresses and data / export in timesharing Output grade , P3 of mouth , P1 of mouth , connect with inside have load resistance of drawing , every one of they can drive 4 Model LS TTL load to output. As while inputting the mouth, any TTL or NMOS circuit can drive P1 of 8051 one-chip computers as P3 mouth in a normal way . Because draw resistance on outputgrade of them have, can open a way collector too or drain-source resistance is it urge to open a way, do not need to have the resistance of drawing outerly . Mouths are all accurate two-way mouths too. When the conduct is input, must write the corresponding port latch with 1 first . As to 80C51 one-chip computer, port can only offer milliampere of output electric currents, is it output mouth go when urging one ordinary basing of transistor to regard as, should contact a resistance among the port and transistor base , in order to the electricity while restraining the high level from exporting P1~P3 Being restored to the throne is the operation of initializing of an one-chip computer. Its main function is to turn PC into 0000H initially , make the one-chip computer begin to hold the conduct procedure from unit 0000H. Except that the ones that enter the system are initialized normally,as because procedure operate it make mistakes or operate there aren't mistake, in order to extricate oneself from a predicament , need to be pressed and restored to the throne the key restarting too. It is an input end which is restored to the throne the signal in 8051 China RST pin. Restore to the throne signal high level effective , should sustain 24 shake cycle (namely 2 machine cycles ) the above its effective times. If 6 of frequency of utilization brilliant to shake, restore to the throne signal duration should exceed 4 delicate to finish restoring to the throne and operating. Produce the logic picture of circuit which is restored to the throne the signal:Restore to the throne the circuit and include two parts outside in the chip entirely. Outside that circuit produce to restore to the throne signal (RST ) hand over to Schmitt's trigger, restore to the throne circuit sample to output , Schmitt of trigger constantly in each S5P2 , machine of cycle in having one more , then just got and restored to the throne and operated the necessary signal insidly. Restore to the throne resistance of circuit generally, electric capacity parameter suitable for 6 brilliant to shake, can is it restore to the throne signal high level duration greater than 2 machine cycles to guarantee. Being restored to the throne in the circuit is simple, its function is very important. Pieces of one-chip computer system could normal running,should first check it can restore to the throne not succeeding. Checking and can pop one's head and monitor the pin with the oscillograph tentatively, push and is restored to thethrone the key, the wave form that observes and has enough range is exported (instantaneous), can also through is it restore to the throne circuit group holding value carry on the experiment to change.译文51系列单片机的功能和结构MCS51电脑芯片的结构和功能。

INTRODUCTION TO MICROCONTROLLERSWhat are microcontrollers? They are what their name suggests. Today they can be found in almost any complex electronic device - from portable music devices to washing machines to your car. They are programmable, cheap, small, can handle abuse, require almost zero power, and there are so many variaties to suit every need. This is what makes them so useful for robotics - they are like tiny affordable computers that you can put right onto your robot.Augmented Microcontrollers and Development Boards In a pure sense, a microcontroller is just an IC (integrated circuit, or a black chip thing with pins coming out of it>. However it is very common to add additional external components, such as a voltage regulator, capacitors, LEDs, motor driver, timing crystals, rs232, etc to the basic IC. Formally, this is called an augmented microcontroller. But in reality, most people just say 'microcontroller' even if it has augmentation. Other abbreviations would be uncontroller and MicroController Unit (MCU>. Usually when I say 'microcontroller' what I really mean to say is 'augmented microcontroller.'As a beginner it is probably best to buy an augmented microcontroller. Why? Well because they have tons of goodies built onto them that are all assembled and debugged for you. They also often come with tech support, sample code, and a community of people to help you with them. My microcontroller parts list shows the more popular types that you can buy. They tend to cost from $30 to $150 depending on the features. This will give you a good introductory to microcontroller programming without having to be concerned with all the technical stuff.In the long term however you should build your own augmented microcontroller so that you may understand them better. Theadvantage to making your own is that it will probably cost you from $10-$30.Between getting a full augmented board and doing it yourself is something called a development board. These boards come pre-augmented with just the bare basics to get you started. They are designed for prototyping and testing of new ideas very quickly. They typically cost between $15 and $40.What comes with the IC?There is a huge variety of microcontrollers out on the market, but I will go over a few common features that you will find useful for your robotics project.For robots, ore important than any other feature on a microcontroller, is the I/O ports. Input ports are used for taking in sensor data, while output is used for sending commands to external hardware such as servos. There are two types of I/O ports, analog and digital.Analog Input Ports Analog Ports are necessary to connect sensors to your robot. Also known as an analog to digital converter (ADC>, they recieve analog signals and convert them to adigital number within a certain numerical range.So what is analog? Analog is a continuous voltage range and is typically found with sensors. However computers can only operate in the digital realm with 0's and 1's. So how does a microcontroller convert an analog signal to a digital signal?First, the analog is measured after a predefined period of time passes. At each time period, the voltage is recorded as a number. This number then defines a signal of 0's and 1's as shown:The advantage of digital over analog is that digital is much better at eliminating background noise. Cell phones are all digital today, and although the digital signal is lessrepresentative than an analog signal, it is much less likely to degrade since computers can restore damaged digital signals. This allows for a clearer output signal to talk to your mom or whoever. MP3's are all digital too, usually encoded at 128 kbps. Higher bit rates obviously mean higher quality because they better represent the analog signal. But higher bit rates also require more memory and processing power.Most microcontrollers today are 8 bit, meaning they have arange of 256 (2^8=256>. There are a few that are 10 bit, 12 bit, and even 32 bit, but as you increase precision you also need a much faster processor.What does this bit stuff mean for ADC? For example, suppose a sensor reads 0V to an 8 bit ADC. This would give you a digital ouput of 0. 5V would be 255. Now suppose a sensor gave anoutput of 2.9V, what would the ADC output be?Doing the math:2.9V/5V = X/255 X = 2.9*255/5 = 148So how do you use an analog port? First make sure your sensor output does not exceed your digital logic voltage (usually 0V -> 5V>. Then plug that output directly to the analog port.This bit range could also be seen as a resolution. Higher resolutions mean higher accuracy, but occasionally can mean slower processing and more succeptability to noise. For example, suppose you had a 3 bit controller which has a range of 2^3=8. Then you have a distance sensor that outputed a number 0->7 (a total of 8> that represents the distance between your robot and the wall. If your sensor can see only 8 feet, then you get a resolution of 1 bit per foot (8 resolution / 8 feet = 1>. But then suppose you have an 8 bit controller, you would get256/8=32 ~ 1 bit per centimeter - way more accurate and useful! With the 3 bit controller, you could not tell the difference between 1 inch and 11 inches.Digital I/O Ports Digital ports are like analog ports, but with only 1 bit (2^1=2> hence a resolution of 2 - on and off.Digital ports obviously for that reason are rarely used for sensors, except for maybe on/off switches . . . What they are mostly used for is signal output. You can use them to control motors or led's or just about anything. Send a high 5V signal to turn something on, or a low 0V to turn something off. Or if you want to have an LED at only half brightness, or a motor at half speed, send a square wave. Square waves are like turning something on and off so fast that its almost like sending out an analog voltage of your choice. Neat, huh?This is an example of a square wave for PWM:These squarewaves are called PWM, short for pulse width modulation. They are most often used for controlling servos or DC motor H-Bridges.Also a quick side note, analog ports can be used as digital ports.Serial Communication, RS232, UART A serial connection on your microcontroller is very useful for communication. You can useit to program your controller from a computer, use it to output data from your controller to your computer (great for debugging>, or even use it to operate other electronics such as digital video cameras. Usually the microcontroller would require an external IC to handle everything, such as an RS232.Timers A timer is the method by which the microcontroller measures the passing of time - such as for a clock, sonar, a pause/wait command, timer interrupts, etc.Motor Driver To run a DC motor you need to either have an H-Bridge or a Motor Driver IC. The IC is great for small robots that do not exceed 1 or 2 amps per motor and the rated motor voltage is not higher than about 12V. The homemade H-Bridge would need to be used if you wanted to exceed those specs. There are a few H-Bridge controllers commercially available to buy, but usually they are way too expensive and are designedfor battlebot type robots. The IC is small, very cheap, and can usually handle two motors. I highly recommend opting for the IC. Also, do not forget to put a heatsink onto the motordriver. Motordrivers give off pretty fireworks when they explode from overheating =>Another interesting note, you can stack IC's in parallel to double the allowable current and heat dissipation.Theoretically you can stack as many as you want, as long as the current is high enough to still operate the logic of the IC. This works for voltage regulators too.Output Indicators Im referring to anything that can be used for debugging by communicating information to you. LED's, buzzers, LCD screens, anything that gives output. The better the indicator, the easier the debugging. The best indicator is to have your robot tethered and print or data log sensor andaction data to your computer, but it isn't always possible to have your robot tethered.Programming Languages The lowest form of programming languagesis the machine language. Microcontrollers need to be programmed with this.These higher languages would then be compiled automaticallyinto a machine language, which then you can upload into your robot. Probably the easiest language to learn would be BASIC, with a name true to itself. The BASIC Stamp microcontrolleruses that language. But BASIC has its limitations, so if you have any programming experience at all, I recommend you program in C. This language was the precurser to C++, so if you can already program in C++, it should be really simple for you to learn. What complicates this is that there is no standard to programming microcontrollers. Each has its own features, its own language, its own compiler, and its own uploading to the controller method.This is why I do not go into too much detail because there are too many options out there to talk about. The support documents that come with the controllers should answer your specificquestions. Also, if you decide to use a PIC, understand that the compiler program (at least the good ones> can cost hundred of dollars. Most microcontrollers also require a special interface device between your computer and the chip for programming which could also cost from $10-$40.Costs With possibly the exception of DC motors, the microcontroller is the most expensive part of your robot. There is just no escaping the costs, especially for the beginner. But remember, after buying all this for your first robot, you do not need to buy any of it again as you can reuse everything. So here is the breakdown of costs. The chip itself, without augmentation, would only cost dollars. But understand the chip is useless without the augmentation, so you would need to do it yourself if you do not buy it already augmented. This could potentially cost just as much with the augmentation, and could cause you many frustrations.If however you are more experienced (and for some odd reason still reading this>, you can customize your own circuit to do exactly what you want. Why have a motordriver when you are only using servos anyway? If you decide to buy an augmented MCU, the cost will range from about $50-$150. To compile your program, you would need to get special compiling software. Atmel and BASIC Stamps have free compilers. PIC's however have fairly expensive compilers. There are some free ones available online, but they are of poor quality in my opinion. CCSC PIC C compiler is about $125, but I think it is worth getting if you are going to use PIC's.You will also need an uploader to transfer the program from your computer to the chip. This generally requires more special software and a special interface device. The Cerebellum PIC based controller has this built in which is really nice and convienent, but for any others expect to spend from $10-$40. People often opt to just make their own as the circuit isnt too complicated.As a prototyper, what you probably want most is a MCU development board. These augmented microcontrollers are designed for the prototyper in mind. To find these augmented MCU's, do a search for 'pic development board,' 'atmel development board,' 'stamp development board,' etc.。

Dormancy of the one-chip computer---restore to the throne in the operation way and improve anti- interference abilityAbstract:Introduce a kind of dormancy of using- restore to the throne in theoperation way and improve the anti-interference ability method of the one-chip computer;Analyse its scope of application, provide and use the circuit concretly; Combine the instance, analyse the characteristic of the hardware and software design under these kind of operation way.Keyword: One-chip computer Restore to the throne /dormancyanti-interference ForewordIntroduction:With the development at full speed of the microelectric technique, the performance of the one-chip computer improves rapidly, demonstrate the outstanding advantage in the operation, logic control, intelligent respect, replaced and enlarged the measuring that the circuit made up, control circuit by digital logical circuit, operation originally to a great extent, use very extensivly. But because it have system halted, procedure run critical defect of flying etc, make it limit in a lot of important application of occasion. A lot of technology inanti-interference , for example set up the software trap, add thehardware to guard the gate in dog's circuit etc, can make this problem havebetter settlement, but still the existing problem: ① Guard the gate dog at the movement, mean and appear mistake already and run some time, this is not allowed in some occasions; ②Procedure appear circulation mistake very much sometimes, but just guard the gate dog control link include and enter, adopt and guard the gate as to such a mistake dog unable to discern; ③In measure and control cycle among the long system, one-chip computer spend wait for the peripheral hardware a large amount of time, will be interfered too when carry out and wait for the order. To these situations, we have tried the method restored to the throne voluntarily in practice, alternate pulse of adopting etc or restore to the throne waking according to external terms to the one-chip computer up. After being restored to the throne each time, the one-chip computer carries out the corresponding procedure, enters dormancy in time after finishing carrying out the task, wait to be restored to the throne nextly. Have solved above-mentioned problems well with this method , and has got better result in the agricultural voltage transformer comprehensive protector experiment. Now take 51 serial one-chip computers as an example and probe into the concrete principle and implementation method, restored to the throne the signal as the high level.1.A principle and implementation method1.1 Restored to the throne the law regularly unconditionallyUse timer, special-purpose clock chip or other pulse generator, produce signal of restoring to the throne regularly according to interval that set for. This kind of method is especially suitable for the measuring instrument. In not running actually, sample the analog quantity of introduction with A/D converter often, then store showing. This course is very fast, but steady for reading, the data per second are only upgraded 1 -2 times, a large amount of time of CPU is used for waiting. Let CPU carry out and enter dormancy directly after the task , restore to the throne and wake by external world up It carry out the next operation, this is to restore to the throne the law regularly In this way can makeanti-interference ability strengthen greatly , have 2 points mainly: ①. At the dormancy, procedure stop run, can appear PC indicator disorderly procedure that causes run and fly. Work time in dormancy proportion 1:9, that is to say 1 s have 0.1 time of s used for measuring, sending off showing, there is time dormancy of 0.9s, the probability that the procedure is interfered is 1/10 while running at full speed, whole anti-interference ability raise by 10 times. ② Because every 1s is restored to the throne once unconditionally, once present the system halted during a job, can certainly resume when restored to the throne next time. As to only instrument that show, some reading mistake that 1s appear accidentally there is no memory to the next measurement, be could bear , belong to “pass” mistake. This kind is restored to the throne the advantage of dog's circuit for guarding the gate regularly, first, change waiting time into a dormancy state, time to shorten and may be interfered; Second, avoided happenning that the dog controls the death circulation of the link to include guarding the gate.1.2 The external condition is restored to the throne the lawSome arrival that export or measure is controlled by the outside. For instance, the hot form. of heating, rotate the pulse produced and calculate heat by hot water water wheels, there is no hot water to flow, there is no heat to export, CPU only need in fact keep number value, do not need to count. Can imagine hot water water wheels rotate when parking warm , CPU idle in will it be will it be one season autumn spring and summer, If let dormancy its , measure have water wheels pulse constantly,anti-interference ability can strengthen greatly. So, so long as link up the restoring to the throne of the pulse of the water wheels and CPU, the water wheels rotate a circle each time, CPU is restored to the throne once, hot form. can work normally , this is restored to the throne the law by the external condition . Similar application have half electron kilowatt-hour meter , go on one count just when the machinery degree wheels and transfers to a circle, users do not need the electricity, CPU has beenknowing the dormancy all the time . The restoring to the throne in the interval not to be regular, but confirmed according to the external condition of this method. In some occasions, the time of the dormancy will be very long, very effective to improving anti-interference ability.2 .The hardware realizes the main point2.1 Restored to the throne regularly unconditionallyGenerally have 2 kinds of methods. ① Use theitimer or thespecial-purpose clock chip to be restored to the throne. Fig1, in order to use the timing circuit that 555 circuit makes up; Can use the clock chips of X1126 ,etc too , wake CPU up with the alarm signal after setting up warning time. This kind of method is suitable when the long interval is made, can also follow the result of this operation ，determine to wake time up in alarm next time temporarily, very flexible and convenient. ②The signal of using the system to be inherent is as reducing the pulse regularly. Use 50Hz worker power make reducing after having a facelift frequently, already omit the timer, gathered the corresponding signal for the phase place which measured the electric current signal at the same time, as Fig. 2 shows.2.2 External conditions are restored to the throneSend external condition pulse to and is restored to the throne the end son after having a facelift. To that above-mentioned water wheels or the ammeter spend a pulse produced, can use Schmitt's trigger to have a facelift; For writing down the instrument of the biggest or minimum，can use the window comparator. In order to realize the electronization that is regulated，can use the electronic electric potential device, establish upper and lower limits with the order of the one-chip computer.2.3 Reduce cycle and restored to the throne the high electricity at ordinary timesIn Fig3, restored to the throne the signal during high level Tr, the one-chip computer is in the state of restoring to the throne, the procedure does not run, anti-interference ability is the strongest; After the high level, the one-chip computer begins to hold the conduct procedure. That is to say, are restored to the throne and suitable for the time that the procedure carries out during the low level Td of the signal, this time should be greater than the execution cycle of the procedure each time. It is restore to the throne cycle and restore to the throne high level of signal take empty than very much important to choose rationally. As to simple to show instrument, restore to the throne cycle determine data break cycle, low electricity is it measure, hancl over all time shown to greater than to want at ordinary times; Otherwise, cant present forever the mistake of the intact executive program.Monolithic integrated circuit in Ts and Tr period all can effectively the antijamming, but is best the unnecessary time arrangement in Tr. When the program time is long, when as far as possible the request reduces Tr, may join the differentiating circuit, like chart 1 center C30, R26, D9.2.4 Treatment of output end sons(1) Restore to the throne straight pulseDuring all I/O mouth of one-chip computer turn into the high level when restoring to the throne. That is to say output for low pin normally, will according to restore to the throne cycle appear the width for the straight pulse of Tr. This straight pulse will influence the normal output, 2 methods are dealt with: ① Connect in parallel electric capacity suppress , capacity confirm according to Tr time that restore to the throne on the son in end. Reducing Tr can be reduced and connected the electric capacity in parallel. ② It is invalid to design the peripheral circuit into the high level. (2) Fault-tolerantChoose the capacity that the output end connects the electric capacity in parallel fault-tolerantly and properly, can realize fault-tolerant control. Reduced cycle in a certain, because interfered exporting the wrong level. Because the keeping function of electric capacity, can't still enable exporting the change to the valid level within this cycle; Next cycle , the mistake is corrected. So, so long as does not make mistakes in 2 cycles in succession, it is very fault-tolerant to export Certainly, this kind of method will make the normal output change lag behind for one cycle, just really reflect the output end son.2.5 has the electricity to measure and restore to the throne manuallySome system is it make some initialize and operate to want at electricity for the first time. Restored to the throne and already become the beginning condition of normal running each time while adopting the way of restoring to the throne to run , it is unable to distinguish and have the electricity for the first time. In some pin connects the electric capacity of one ljIF to the ground, measure this pin after being restored to the throne, if low level to have electricity for the first time. Give system set up one restore to the throne button, that is to say a common one manual to restore to the throne, this button is not joined and being restored to the throne in the end, is connected in parallel in the electric capacity both ends to the ground of above-mentioned pins.3. The software realizes the main point3.1 is it resume with zero clearing RAM to outputRestore to the throne the last all pin turn high level into , is it should taKe place unnecessary change for low pin to make regularly, so, should resume the state.of all pins immediately after being restored to the throne. There are 2 kinds of methods : ① Analyse and judge immediately after being restored to the throne this time, provide the state of the pin according to the need; ② In being RAM it is the last last state that come down,these RAMs when restored.To the throne regularly can the zero clearing one; But electricity or manual to rstore to the throne when pushing in conformity with zero clearing, is it embody to want when the software is worked outing at the beginning. If calculate time allows, try one's best to take method 1. Restore to the throne cycle probability made mistakes to calculate very little, according to 2 for the 2nd time in succession. 4 output end son that narrate connect treatment method of electric capacity in parallel, can reach kind anti-interference result very.3.2 realizes crossing over and is restored to the throne alternate time sequenceregularly to controlWork in way of restoring to the throne now, start anew and carry out the same procedure repeatedly each time. Can be divided into 2 kinds of situations: ① As to simple to show instrument, carry on measurement ，send off showing after being restored to the throne each time, have causality between restoring to the throne twice . need is it switch over to the dormancy to waiting original only. Should pay attention to,measurement, give total time used to show is it is it restore to the throne low electricity at ordinary times to smaller than to want, otherwise can't present forever the mistake of the intact executive program. ② For having application that time sequence controlled , after being restored to the throne each time , should check first that see the sign left last cycle , in order to determine what is done this cycle . That is to say every is it restore to the throne operation of cycle to stride , by is it transmit to indicate all, these indicate while leaving in inside RAM , the zero clearing only when have the electricity for the first time. For example, the protecting synthetically device of above-mentioned voltage transformer , is restored to the throne regularly according to the interval of 20ms. It reaches the normal working state through, certain movement order after having the electricity, such as Fig. 4; Write a part of the procedure of the software according to this movement, such as Fig.5.In 4 Fig, act as person who protect the beginning at the electricity, is it transmit power 0 to try at first. 5s, points out and transmits power soon; Transmit power formally after waiting for 30s. It is start-up time in 1s after transmitting power, does not measure the electric current. Start after finishing, if all going well, the location is put" normal sign ", person who protect restore to the throne cycle enter normal running in the next one. Try 0 that transmits power. 5s is it is it realize to count once restoring to the throne to delay time, restore to the throne time 20ms each time. At having electricity for the first time, make all zero clearing to inside RAM, make it is it time Ts to transmit power not to try =Dormancy after 25. After restoring to the throne, is it have electric pin to have electricity for the first time already, is it is it is it is it time the measuring of Ts to transmit power to try to get to go on to measure next time. If Ts * 0, is it in is it prolong period to transmit power, is it enter dormancy after the 1 to reduce Ts to prove. Act as Ts-1 = 0, the course which waited for 30s that should enter and lose electrical power. Just when Ts decreases progressively to 0, make it is it indicate to wait for not to lose electrical power Td =1500. When the procedure is restored to the throne beginning again, measure to Ts =0 but Td * 0, is it is it is it transmit power to try to cross already to indicate, at is it wait for the course of 30s to lose electrical power now. In this way, the whole process is transmitted each other by such these parameters as Tr, Td , Ts etc, go on step by step.Result:Conclusion Anti-interference is an important problem in an electronic design, especially Important in the one-chip computer. This is because the one-chip computer has procedures to run particularity that flies, the consequence that it is interfered may be the system halted, may send out various kinds of mistakes or illegal movements before the system halted too, make the whole system produce the mortality mistake. So, only guarantee it is not enough yet for one-chip computer not to crash, study how to reduce the risk interfered, it can befault-toierant how is it after and make mistakes. This text is it act as some exploration from two these to try hard, hope these elementary opinions can play some function of casting a brick to attract jade, helpful to everybody; Hope too every colleague explore together, improve our design level together.在一个芯片的计算机恢复到休眠---宝座的运作方式，提高抗干扰能力摘要：介绍了一种使用休眠，恢复到在theoperation方式的宝座，提高了单芯片计算机抗干扰能力的方法，分析其应用范围，提供和使用的电路concretly;结合实例，分析的运作方式下，这些种类的硬件和软件的设计特点。
