本科生毕业设计（翻译）Multifunctional Intelligent Wireless AlarmSystemAbstract:Making use of rich inner resource of FPGA(Field Programmable Gate Arrays), a wireless alarm sending system is designed. It includes encoder, FSK(Frequency Shift Keying) modulat ion and every channel’s control circuits, which can decrease volume and increase reliability of the alarm system.The demodulation of receive system is realized by an application specific integrated circuits MC3372.

It can send an alarm to the host when there are some cases in stand-off areas, and the system will display on rotation multiple cases’ area codes . The transmission distance is greater than 4Km in open zones. User can install more than one type sensors simultaneously, for example, smog sensor, combustible gas sensor or burglar sensor. Experiments show that the wireless alarm system has the strengths of high reliability, high anti-disturbance ability and low error-alarm rate. It can entirely meet the needs of alarm fireproofing and guard against theft, etc.Keywords: communication; Alarm systems; Frequency Shift Keying; Micro-controllers; Field Programmable Gate ArraysI.INTRODUCTIONCompared with a wired alert system, a wireless alarm system has characteristics of covertness and ease of installation. It is especially effective when transmitting between long distances in a complex landform situation. Made up of FPGA (Field Programmable Gate-Array), the encoding module in the sending system creates the address signal, FSK (frequency shift keying) modulates the signal and each channel’s controller signals. Using FPGA to replace MSI/SSI (Middle Scale Integrated or Small scale Integrated) digital circuit devices, not only increase the reliability and the resistance to interference of the alarm system, but it also decreases its volume and makes the system easier to install. Since used 7 bits binary number to express the address, up to 128 channels sender can be installed. The decoder consists of ASIC (Application Specific Integrated Circuit) and SCM in the wireless alarm receiver system, which can effectively decrease the error-alarm rate.II.THE SENDING SYSTEM PRINCIPLEEach stand-off is equipped with a wireless sending system,and corresponds with a 7 bits address identifier in binary. Once a case is detected by a sensor in any stand-off, a control signal of this area is sent to its encoding circuit via interface circuit, which converts the area’s 7bit address identifier into FSK signal. Then FSK signal is transmitted into a frequency modulation circuit for frequency modulating. After power amplification, the frequency modulation electromagnetic wave is emitted via antenna. Onecharacteristic of the sending system is discontinuous sending. In other words, the sending system does not send signals when there is no case, and do keep sending when there is an alarm situation, so as to provide chances to send signals for other stand-off areas.A.The Encoding and Controlling Circuit ConfigurationThe digital circuit part of the encoding circuit is made by a FPGA chip which includes 8 modules.Formed by D triggers, module ‘dff1’ is the interface between detector and encoder. Module ‘oscillator’ combines with some external resistors and capacitors to form a controllable low frequency multivibrator. Its control signal is the output of ‘dff1’---Q1. It does not vibrate when Q1is equal to 0, and if Q1is equal to 1, it vibrates to generate low frequency square waves. If some cases appear in the area, the oscillator controls the mo dule ‘SENDER’ to send electromagnetic wave discontinuously. The module ‘circular_shift_r’ is a parallel input serial output circular shift register. The bit A0～A7 are the parallel address code input terminals, which are joined to high or low voltage level according to the encoder requirement. Q8 is the serial output terminal of the address code. Module ‘dff2’ is a control circuit that is made of some JK triggers. Its setup signal is Q1, which also acts as a trigger signal after delay. Q2 acts as the parallel-in-serial-out control terminal of the‘circular_shift_r’ module. When Q2 is at high voltage level,circular_shift_r’ performs parallel input. When Q2 is at low voltage level, ‘circular_shift_r’ executes serial output. The module ‘delay1’ is a delay circuit composed of D triggers.The module ‘division’ is a frequency division that creates three different routes frequency output signals, two of which branches and act as FSK modulating signals: f1 and f2. The other branch acts as a triggering pulse for modules dff1 and delay1, and alsoacts as the clock pulse of ‘circular_shift_r’for performing serial-out. The module ‘MUX’ is a 2 to 1multiplexer. Its control signal is the output Q8 of‘circular_shift_r’. When Q8＝0, ‘MUX’ produces the signal f2, and when Q8＝1, it exports f1. The module ‘delay2’combines with some external resistors and capacitors to form a delay circuit. Its function is to give workers some time to leave after installing the system. The sending circuit does no work within the delay time, no matter whether K1(detector) is on or off. This is the external connection drawing of the FPGA chip.B. The Working PrincipleAs shown following, the working principle of the alarm system is as follows: when the power of the sending system turns on, the input of the ‘dff1’ is at low level. Then its output terminal Q1 is at logic value ‘0’, NQ1 is at logic ‘1’, and a external light-emitting diode (LED) is lit to indicate the power is on. The signal Q1 is sent to the setting terminal of ‘dff2’ to set terminal Q2 at high level. The high level Q2 will set ‘circular_shift_r’ into the parallel input address code mode. At this time, the outer transistor N2 is at saturation state and N3 at cut-off state. This makes the sending circuit at a passive state, therefore, the circuit will not work. Hence, the circuit does not emit carrier wave if there is no case, and it is at low consumable power state.Once some cases appear, the switch K1 is on. The terminal D of the ‘dff1’ turns to high level immediately, and the output Q1of ‘dff1’ is set to high level at the rising edge of the clock pulse. It makes the setting terminal s of ‘dff2’ at high level too. The ‘dff2’ now is at normal working state. After delaying by module ‘delay1’, the former edge of the Q1 pulse will trigger ‘dff2’ to output low voltage, which will make the transistor N2 off, N3 on, and the delay’s normally open contact will be closed. The electric power supply to the sending circuit is on, and the circuit begins to work normally.Simultaneously, if Q2 is at logi c 0, ‘circular_shift_r’ will be change to serial shift state and export address signals. When the address code is 0, the output of ‘MUX’ will be f2. And when the address code is 1, the output will be f1. Terminals f2 and f1 act as the modulation signal for modulating the carrier wave. In this way, the address code is sent out at the first cycle of the low frequency oscillator. At the second cycle it stops sending in order to give other stand-off a period of time to send. After the third cycle, repeat the procedure above.From the discussion above, we have the conclusion that the encoding and control circuit have the function to display when the power is on, time delay for human to leave the spot, low power cost mode for waiting case, discontinuity sending and FSK modulating etc. It is more flexible and has more functions than many encoder ASIC.III.THE CONFIGURATION AND PRINCIPLE OF THE RECEIVING SYSTEMSet in guardhouse, a set of wireless receiver takes charge of monitoring all stand-off areas. The principle of the wireless receiver is show following. Passing by the low pass filter, the received modulation signal is sent into the high frequency common-emitter and common-base configuration cascade amplifier for amplifying. Then the signal is sent to the intermediate frequency modulation amplifier via the dual tuning circuit, i.e. sent into the input terminal (16th pin) of an ASIC chip (MC3372) to do mixing. The oscillate frequency of the local oscillator circuit is 455KHz higher than the received signal. Delivering to the first pin of the chip MC3372, the signal will mix with the external signal to get 455KHz intermediate frequency signal. After filtering, the intermediate frequency signal is first delivered to the 8th MC3372 pin to do frequency detection, and second amplified by an inner lowfrequency amplifier of the chip MC3372, then the 9th pin exports the baseband signal. Amplified by a low frequency single transistor, the baseband signal is rectified by two steps Schmitt gates (CD4584) to turn into a FSK signal, which will be sent into pin 3.0 of MCS to be decoded.MCS in this system is chip 89C51, which joins an outer 12MHZ crystal oscillator. Its timer T1 act as a baud rate generator in mode 2, and SMOD=1,300 baud/sec. serial port is selected in mode 1, which means an asynchronous communication mode, 10 bit per frame in which the lower 7 bits of the 8 data bit is the address code, and the 8th acts as the parity check bit. The system uses even check.When receiving an address code, the MCS firstly performs parity check. If it is correct ,then ,the MCS compare their value and takes out 7 bits address code and stores it into data buffer in memory. These procedures repeat 3 times in order to identify the 3 address codes. If the 3 address codes are the same, the MCS will confirm that the receiving address signal is an effective alarm signal, that is to say, the address code is not a noise signal. It then triggers the alarm circuit to send the alarm sound. At the same time, the code number will display on the LED indicating which stand-off triggered the alarm.The LED uses a dynamic scan display method. If there are more than one stand-off areas have cases simultaneously, the MCS will display their code number in turn at 3 seconds intervals. The alarm audio process circuit uses a NE556 dual time base circuit chip to form a dual audio frequency multivibrator, which will give off a ringing alarm sound. System could configure sensors use for alarm of fire,combustible gas and theft.IV.ANTI-INTERFERENCE MEASUREIt is important to heighten the anti-interference ability for wirelesscommunications. anti-disturbance measures takes form in the hardware. For example, one should reasonably arrange the PCB (printed circuit board)，increase power decoupling, and place the high and low frequency filter reasonably. Since the receiver system includes high frequency circuits, separate the analogue circuit and digital circuit chip, and make each have its own ground. To guard against external and internal interference or high frequency radiation, put the high frequency amplifier and middle frequency amplifier channels in a metallic shield box and the MCS system into another metallic shield casket. Adopt FSK modulation, double tuning select frequency and ASIC demodulation. All of these measures can effectively decrease interference to the system. For software, use the modular structure to design the software system. Continuously distinguishing address code several times and by parity check can dramatically reduce the error-alarming rate of the system.V.THE ENDINGThe design of software and hardware in this alarm system is reasonable. Its reliability is observably increased, and the error alarm rate is decreased. Experiments show that the error alarm rate is nearly zero when disconnecting the detector. The transmission distance is greater than 4Km in open zones When connecting microwave dual discriminating theft-proof detector （DT-400 Family）, the error alarm rate is less than 4 times every 1000 hours. Since working in the discontinuously sending method at 300baud/s, the alarm system can work reliably as long as the time gap between two sending systems is less than 0.2sec. In fact, it can meet the need in actual applications.Intelligent Residential Security Alarm and Remote Control System Based On Single Chip ComputerAbstract：For to steals, robs and so on accidents to carry on the effective monitor and the warning, unified using the MCU AT89C51 controlling technology and the infrared detection technology, one kind of wireless burglar alarm has been designed, it including hardware and software two parts; The hardware part is composed by the infrared sensor, send and receive module ,MCU, acousto-optic warning and so on; The software part is composed of the main program and music subroutine.

People's living conditions have changed, Such as the living environment’s security and how comfortable they feel. So the intelligent residential building’s automatic emerge as the times require. Intelligent residential must have safety precautions, anti-theft alarm, fire alarm, toxic gas leakage automatic alarm and emergency call. It is able to implement remote control for the key equipment power. In recent years, with the progress of technology and economy, the electronic anti-theft alarm system has rapid development and a very wide application. Now it does not only apply in many important government departments, but also apply in the family.In-depth study on various alarm device, we have designed intelligent residential security alarm and remote control system on the basis of single chip computer. The system is based on 89C51 single chip computer, hasintelligent residential burglar alarm, emergency call alarm, fire alarm, toxic gas leakage automatic alarm and remote control. It is able to call the police hotline number. It is able to use voice alarm and show alarm occurred address. Users can set up and modify password for it. It can be recordable and voice suggestion and make use of the telephone to remote control. Calling when is not at home, it can use password to enter remote deployment and remote control the power of electronic appliance.The system makes use of communication equipment to realize multi-channel detection, scene alarm, emergency alarm, fire alarm and toxic gas leakage automatic alarm. It realizes remote voice alarm function through the automatic dial-up telephone. It directly parallels on the telephone lines, then may be used. Before used, user will be required to install the detection device in place where being watched by people. It must be set up alarm telephone number, recorded voice alarm. The alarm system has design innovation, multiply function, low cost, high reliability and so on.II.SYSTEM COMPONENTIntelligent residential security alarm and remote control system constitutes as shown following. The system is through telephone interface circuit and telephone network to link up. 89C51 single chip computer dominates by MT8880 Dual Tone Multi-frequency (DTMF) codec with the telephone network to exchange information. When the detection of dangerous situations, the dangerous situation coded signal transfer from the corresponding detection module through the antenna to master chip. The master chip brings the corresponding alarm information according to received signal. This part is to complete by the voice interface circuit, which uses ISD1420. After users call the number of system, users can control appliances according to sound by the voice interface circuit.The system components are made up of detecting circuit, wireless transmitter-receiver circuit, telephone interface, voice circuit, DTMF codec circuit, telephone signal detection circuit and the main control circuit. Each module is described as follows:A.Detecting CircuitThe part circuit is as the detection part of the whole system, used to detect theft case, fire, toxic gas leakage and emergency call signals. Theftproof detection is to complete through pyroelectric infrared sensor. Sensors are installed on the balcony, windows and other place where thieves are easy to enter. The part circuit is at the ready state under normal circumstance. Sensors catch theft information when someone enters the scope of the surveillance. Then, wireless module will send the information to the 89C51 single chip computer. The detection of fire and toxic gas is to complete by the corresponding detection sensors, emergency call signal is sent from user hand-hold remote control.B.Wireless Transmitter-receiver CircuitThe transmitting and receiving circuit of the part makes use of CMOS manufacturing process produced by a low cost PT2262/PT2272 wirelessremote control module. The operating frequency of it is 2 MHz and the communication distance of it is 100 meters above. Under normal circumstances, transmitting and receiving modules are in dormant status. The module is in non-dormant status when be in danger, then coded signal is transmitted. The receiving module has received high-frequency signal decode, generating interrupt signal at the same time.C.Telephone InterfaceHere shows telephone interface circuit. The phone lines normal is above 48V DC voltage and optocoupler is not conducting. When the phone lines are ringing signal which is 25±3V sine wave, Optocoupler is conducting, generating interrupted signal to the mainframe. The relay will be connected to J1,after mainframe detected ringing signal many times, then load resistor connected to a telephone line, that computer to simulate the extraction process. Since then, the system access DTMF signals from the TONE of coupled transformer, transmits voice signals from VOICE of coupled transformer. To disconnect the system, the system rings off.D.Voice CircuitThe voice circuit of system is used to generate alarm information and hint information. Using specialized voice integrated chip ISD1420, which provides 20 seconds recording time. Using subsection record, master audio recorder provides the starting address.E.DTMF Codec CircuitUsing MT8880 codec chips, to complete dial up function and decode passwords and control commands which are sent by users.F.Telephone Signal Detection CircuitThe telephone signal detection circuit uses pulse reshaping circuit design. The signal must be amplified by the signal amplifier circuit, then, to generate square wave signals to main control chip by comparator. Phone signals including dial tone, busy tone, call waiting tone, ring back tong, network busy tone relies on software to identify.G.The Main Control CircuitThe system adopt 89C51 chip as main control chip, the main controller call by detecting ring tone. Tone control circuits broadcast voice tone, to coordinate the competence of users who have complete remote control electrical appliances. On the other hand, Mainframe controls dial-up circuit given the preset number according to receiving alarm information.According to the alarm type of telephone sound, determine to call police or tell user the information. User may preset passwords, telephone number and record, and so on.III.SYSTEM SOFTWARE DESIGNSystem software is composed of main program, remote control subroutine, warning subroutine. In order for the system in idle time to enter a dormant mode, all the tasks are completed in interrupted service routine.A.Main program designHere shows main program flow chart. It mainly accomplishes initialize work, then the system enters a dormant mode. Whether there is password input or imported alarm. The results are processed accordingly. A method of determining whether to provide a user with access to the security system,enter a user password for verification by a program in a computing device. When valid user leaves, the main program waits for some time, automatically enters the maximum security state. The main program regular calls watchdog handling procedure, in order that the system is not normal reset.B.Remote Control ModulesWhen there is a ringing signal, remote control modules generate external interrupt. The number of the ring counts in interruption procedure, if the number is more than six times, the system hangs off, broadcasts hint tone to the telephone network. Then checking user passwords, if passwords are valid, user may control the work of electronic appliances. And the times of password input are limit. Check whether connection is overtime or not, hang up if it is overtime.C.Remote Alarm ModuleAn interrupt handler of remote alarm, also known as an interrupt service routine (ISR), is a callback subroutine in an operating system or device driver whose execution is triggered by the reception of an interrupt. When receiving module receives signals, main controller generates interruption, is out of dormant. Proceedings interrupted in this way shall continue from the point where they were interrupted, if making the interrupt trigger. For example, when the system withdraws from a defend position, the system ignores the security which has received alarm signals.After dialing has finished, we must judge by phone tone whether the call has been put through. If not, we want to repeat the dialing. We just hang up the telephone then repeat,otherwise, play alarm information to the other. The function is to complete by signal tone detection routine. System must identifysignal tone, in order to identify the signal tone, we must know the characteristic of signal tone.IV.THE SYSTEM TESTING SHOULD MEET THE FOLLOWING REQUIREMENTa.Guard against theft and alarm system: Be able to dial preset telephone number and alarm telephone number, tell people by phone tone where the accident has happened.b.Emergency alarm: Be able to dial preset telephone number and emergency telephone number, tell people by phone tone where the accident has happened.c. Fire alarm and record hint: Be able to dial preset telephone number and fire alarm telephone number, tell people by phone tone where the accident has happened. And there is toxic gas leakage automatic alarm and emergency call.d. Be able to set up password and alarm telephone number, then modify theme. Remote control the power of appliancesV.THE EXPERIMENTAL RESULTSAccording to the program flow diagram with C or the assembly language compilation main program and music subroutine, carries on the debugging in the Keilc51 environment, will debug the good procedure using the programmer to solidify to MCU AT89C51. With the infrared sensor, the launch module, the receive module, the MCU, the acousto-optics alarm circuit welding on the PCB board according to the request, puts through the power source, the green power light is bright, indicated that the power sourcework is normal; When separation alert control switch, the alarm circuit does not work, therefore when some people intrude in the infrared launch area, also will not have the warning, when after closed alert control switch, the indicating lamp will be bright, indicates the alarm circuit in the work, when this time some people will intrude in the infrared launch area, will have the acousto-optic warning, namely the buzzer will send out music, red light emitter diode twinkle. The alert control master switch's function, causes the infrared burglar alarm's use to be more convenient, when the master wants to greet the visitor, may separate the alert control master switch, the visitor walks into the guard area not to report to the police; When the master wants to guard against theft, then closed alert control master switch, when has the unexpected visitor to intrude the guard zone time, will carry on the acousto-optic warning.VI.CONCLUSIONThis paper presents intelligent residential burglar alarm, emergency alarm, fire alarm, toxic gas leakage remote automatic sound alarm and remote control system, which is based on 89C51 single chip computer.
