The modern automobile development technology target from users Consider, first is safety, comfort and economy. From the ring The perspective, some of these requirements and low emission method Rules and policies of contradictory. Thismeans that the human to steamCar emission control technologies of performance requirements in government (environmental protection) departmentDoor and in automobile industry development is shown on this problem outThe contradiction and mutual coordination.2 Environmental protection and of the development of automobile industry coordinationIn order to control the car emissions, since the early 70 s on the world to create the automobile exhaust emission regulations (government departments door)，After constant improvement and correction, regulations become more and more strictly. Table 1 list Europe and the us federal government auto emissions regulations of the development process. In fact, sure car exhaust emission regulations limit is not difficult, but the problem is, in order to meet the requirements of the regulations, the auto industry into human, material and financial resources is countless. In addition, the development cycle usually need three to five years. Therefore, in the formulation and implementation of foreign auto emissions regulations, will the next round of the implementation of the regulations time and content, reported that in advance The auto industry has enough time to take appropriate measures. Therefore in the implementation of laws and regulations will not appear regulations and implementation of the auto industry production and development of the conflict.Recently, some place in domestic enacted or promulgated and implemented new auto emissions standards,The relevant departments of the state in the new national standard also specified.The focus of the discussion on these standards is to carry out fixed number of year. From the Angle of environmental protection, in order to and the international community, the implementation of the car as soon as possible strict emissions standards is imperative. But must leave room for the auto industry. Past due to various reasons, even make national standards, in fact no strict enforcement. On the other hand, formulate standards must also have a "advance", can't make the automotive industry.Improve the quality of atmospheric environment is a global problem, from auto industry to see, it is necessary to put into the corresponding human, material andfinancial resources to reduce vehicle exhaust emissions. If hold fluky psychology the, then, will eventually be out by the market.3 Reduce automobile exhaust emission pollution may wayReduce exhaust of atmosphere pollution can be from the following two aspects.（1）Reduce pollution emissionsReduce emissions is to reduce pollution and automobile exhaust emission, here related to:a.Auto technology. In addition to the engine technology, also related to power automobiles transmission system optimization, and the vehicle technology.b. The road traffic planning and design. Rational planning road, ensure good traffic road conditions and sparse traffic density, reduce automobile engines in idle speed and low load, so can reduce running time of the auto emissions;c. The car driving conditions. Car in off-design conditions (acceleration, slowing down, idle speed) and emission performance in relatively poor working conditions, the operation will greatly increase emissions. Here except and road traffic factors outside, and drivers driving habits have closely contact;d. Repair and maintenance. The heavy-duty automobile repair and maintenance is to guarantee the low pollution, one of the important measures.（2）Improve the diffusion and absorption in environmentHere the term car emissions (exhaust, fuel evaporation, the crankcase ventilation, etc) in the atmosphere spread. It involves:a.The geographical environment, such as location, wind power, wind, temperature and light, etc;b. The overall plan of the city, such as city buildings, green, etc.This shows, reduce automobile emissions is not only the auto industry and the environmental protection department, still with the vehicle management departments, public security department (the yearly check of vehicle license plate, permit system), the urban planning, the road traffic department are closely linked. Therefore, reduce automobile emissions is a systems engineering, need each department coordinate and work together.4 Reducing gasoline vehicle exhaust emissions measuresDomestic auto emissions in the world of advanced quality and low emission vehicle, there is a certain gap compared. If only on its own technology strength, to shorten in a short time. Therefore, the "jumping" (the introduction and absorption of advanced technology) measures is feasible, but also need to own development, because a technical measures will not be suitable for all kinds of models for different models, need a lot of matching the experimental research. This needs related department to make reduce auto emissions overall, sustainable planning.From lower auto emissions in terms of technology, according to the domestic and foreign long-term the results of study show that the different technical measures are likely to reduce emissions. But at the same time also can increase the system's complexity and affect other performance. Therefore, must be balanced various performance indicators.Reduce vehicle exhaust emissions not only with engine performance, but also related to power automobiles transmission system matching, optimizing the parameters of the close contact.In addition, also need according to the technical conditions at that time and auto emissions regulations and establish reasonable limit the technical route and research and development strategy. In addition, also need according to the technical conditions at that time and auto emissions regulations and establish reasonable limit the technical route and research and development strategy. German BMW to our company on the series of vehicle engine emission performance of low development research, for example, from on the whole, ensure power, economy and the premise of comfort, reduce the auto emissions technology lines from three aspects:①The camshaft adjustment system;②The mixture formation measures;③The gasoline engine control strategy. In view of the different models and the scope of application of requirements, take different approaches.⑴4 cylinder machine seriesThis type of the main requirements is low and medium speed range reduced emissions, reduce noise and fuel consumption, and ensure that the dynamic performance of the higher driving. For this, the through the expansion tank andincrease the trip in order to increase emissions; Optimization air intake system; Further development and improvement of the gasoline engine control functions and technology measures.⑵6 cylinder machine seriesFor this series of vehicle gasoline engine is required in the low speed and user commonly used speed range has large torque, can meet the LEV and European emissions of EUⅢrequirements, but also reduce the noise and fuel consumption. Therefore, the exhaust all the camshaft variable timing control system; In the secondary air cylinder head integrated channel; The characteristics of field control cooling medium temperature control system; The inlet resonance system. Near the gasoline engine exhaust chamber should Lord catalytic converter structure.⑶V model 8 cylinder engineV model 8 cylinder engine the gasoline engine for the BMW 5, 7 series models, the requirements to senior is further reduce emissions and fuel consumption, noise, and to ensure that the corresponding models of high power safety. Therefore, in 6 cylinder machine, and on the basis of using modern technology, such as the timing of the variable air intake system, adjust the camshaft with liquid cooled generator and the transmission oil and water heat exchanger, and close to the gasoline engine before technology such as catalytic converter.Using the inlet valve control system of the variable CAM, NOx in the steady-state can reduce by 50%, through the internal recycling HC gas down by 10%. In the warm-up phase, through the camshaft phase adjustment and put off the ignition can greatly improve the exhaust temperature, so as to reduce HC emissions.⑷V model 12 cylinder engineFor lower V type 12 cylinder engine HC emissions purpose, in V type 8 cylinders of the gasoline engine based on technology, and then using air around the injector and the characteristics of temperature and cooling medium field control method. In addition, also introduced a new concept of the waste gas purification, HC adsorption device, electrical heating catalytic converter and the traditional three-way catalytic converter and secondary air system combination technology.It is because of various models of emissions levels of emissions requirementsand the difference, so used different technical measures to coordinate, compared to solve the vehicle emissions caused by the lower cost increases and other performance could fall of conflict.5 To satisfy the more stringent emission regulations exhaust after-treatment technology developmentTraditional catalytic converter light-off temperature 250 ℃to 300 in usually ℃in gasoline engine, the cold start after 2 min or so time to reach the catalytic converter can temperature, and right now the exhaust fumes have accounted for about 80% of the total amount of circulation. Facing the more strict emissions regulations the LEV and European emissions of EUⅢrequirements. Therefore, to improve the cold start when the performance and shorten the catalytic converter purification to light-off temperature of the time became research and development goals. Therefore, can use such as stepless adjusting system, the camshaft exhaust air intake system controlled, delay the ignition, to improve the combustion stability and secondary air system and the waste gas aftertreatment systems, etc.6 conclusionFrom the above analysis, we can see that reduce vehicle exhaust emissions and development of the technology of closely related. The course of development and also by auto emissions regulations restrict, the coordination aspects in the contradiction is not. In addition, car emissions by many parameters constraints.Through the car design, the gasoline engine performance design, control system and coordination, will be more and more complicated by the system to meet SULEV like ULEV and EUⅢand EU Ⅳand strict regulation limits of requirements.

什么是垃圾车软故障垃圾车常常在保养，时时在关心，可即使你有最好的保养方案，一两年后大数的车主还是会明显感觉到垃圾车的驾驶性能和工作效率在不断地下降......却不知道其中的原因是什么？比如:垃圾车电子电路系统老旧损耗会导致车子越来越耗油，油门不顺、点火效率不高、换档不畅，动力不足等这些牵一发而动全身的小问题都跟爱车的电路系统有关，最后变成无法解决的难题。

许多朋友的爱车临老时所面临一堆这样那样的小问题，看似小小的电力问题会使爱车出现一连串的毛病？这些问题和现象都可以称为“垃圾车的软故障”。

据统计车身上60%以上的部件和机械系统都需要直接或间接使用电力才可以工作。

现代垃圾车电子技术的运用和发展就是越来越多的部件采用电子控制。

特别是电子传感器的使用，可以分类为测量温度、压力、流量、位置、气体浓度、速度、光亮度、干湿度、距离等功能的传感器，它们各司其职，一旦某个传感器失灵，相对应的装置元件就会不正常甚至不工作。

种类繁多的电子元件,电器设备的运用，使垃圾车的功能增加了许多自动化度程也越来越高了,但相应这些系统上的软故障也增加了。

如果想要有效的化解这些问题,就必需要更加全面了解和认识到垃圾车电路系统,电子元件的保养。

尽量减轻这些设备的工作负荷,延缓它们的损耗和电路系统上的老化，尽早用垃圾车电力保护器可以有效的预防和化解这些电路系统上的软故障。

附录AThe Design of Pull Arm Garbage Truck1The introduction of Pull Arm Garbage TruckPull arm garbage truck is equipped with two types of chassis that has a trunk load and unloading functions to pull arm device-specific vehicles. It can be achieved with car trunk the combination and separation, while the bulk of the trunk to achieve self-unloading cargo operations. The model has been widely used in foreign countries, often in the domestic industry as a sanitation refuse collection vehicles. 5 t pull arm garbage truck is one of the commonly used models, compared to 8 t Arm pull over large tonnage trucks, the pull-arm device structure is relatively simple and easy to domestic Manufacturers; And large tonnage often imported pull arm device. Domestic Manufacturers producing 5 t pull the car pulling the boom arm structure of the device, although about the same, but the important structural parameters of the selection and design of different structural arrangement, it will directly affect the car performance]20[.2 Pull the boom structure and principle of the device2.1 The structural characteristics of pull-arm device5 t pull arm garbage truck pulling device consists of pulling the boom arm and pull arm cylinder, the United Moving frame, trunk insurance hook and cylinder, and the frame. La Boom device structural arrangement shown in figure 2, pull telescopic arm is not used right-angle bend structure. the end of the cylinder and pull the piston rod side arm hinged on the hinge pivot B; Another linkage frame front end and hinged at the hinge pivot C, the formation of a rotary arm pull heart. Cylinder head cylinder arm pull side hinged front frame on the hinge pivot A; linkage frame hinged rear axle frame rear hinge pivot D, the formation of linkage rotary frame heart. Insurance linkage trunk rack hook set the hook cylinder and insurance cylinder.2.2 The working principle of the device arm pullPulling garbage truck arm by pulling the device to complete the function of two different dynamic, for boxes and dumping. When the pull device for boom box action, the first cylinder insurance hook action open the trunk insurance hook, trunk lift insurance. Pull lift arm cylinder piston rod elongation from the pull arm, pull arm to pivot around the hinge C clockwise rotation, the hook arm to pull back move. If the frame is equipped with a trunk, the trunk was pushed home ground. When put on the frame, so that the first hook retractor trunk rings, and contraction of the piston rod, pull arm to hinge pivot counter-clockwise rotation axis C, will put on the flat trunk, the insurance cylinder hook action, pull carriagesinsurance hook fixed to the frame to the trunk.When the pull-arm device dumping action, and action for different box, trunk insurance hook dump in the whole process to ensure that tension in the arm and trunk are not isolated, that is pull arm、the linkage through the trunk rack and trunk link between the insurance as one of the hook, by the deputy rear frame hinge pivot clockwise rotation axis D, lifting carriages lifted until the refuse rubbish. Trunk reset, as long as the retraction of cylinder piston rod pull arm, the pulling arm body still hinge pivot point D is the shaft counterclockwise rotation, until the trunk reset.3 La Boom Selection and design of device structure parameters3.1 Device to pull the boom pivot hinge arrangement and geometry of the main structureDetermined by the following three areas:a. Arm by pulling a dump truck performance, it is 5 t pull the best selection of cars from the arm unloading chassis, the chassis can be selected according to the length of pull arm device to determine frame the total length. To ensure the car to pull arm for changing trunk and dumping action by the force of the chassis reasonable and complete the dumping arm pull action pivot hinge rotation axis D of the location should be arranged in behind the rear spring plate from the chassis rear bearing axis, the spacing is about 0 ~ 100 mm.b. According to the first hinge pivot D arm pull for me the beginning of the selected pivot hinge rotation axis C. In the design and production of the actual process of pulling the car arm in arm had appeared during the pull action although the initial state, pull arm lift carriages, failed to pull arm pivot around the hinge C rotation, but with the linkage frame with the rotation around the hinge pivot point D, which can not get trunk open the beginning of fall; when lifting a certain height, the action of gravity in the trunk, the hinge will pivot C a sudden fall, so pull arm, the linkage frame and carriages suddenly drop, resulting in relatively large; in hit, resulting in extremely unsafe for me a smooth action. To resolve this problem, determine the hinge point C of the axis position is especially important. First the one hand, the horizontal axis of pivot C can not above the level layout of pivot D. In addition, by the hinge can pivot C stress analysis know, the hinge pivot axis of C must be below the level of tension hinge pivot arm cylinder head horizontal axis, while the hook arm pull-start action must be arranged in the vertical axis of the hinge pivot between C and the hinge pivot left foot.c. Important geometrical parameters arm pull a pull arm foot radius of gyration for pull the oil boom turning radius of the cylinder piston rod end of radius of gyration of the angle between the two radius. From the above points analysis we know that, The smaller of radius. The greater the force needed to pull the smaller cylinder arm. Meet the requirements underthe premise of arms-for-me pull-foot turning radius, the smaller the better, La boom cylinder rod side radius of gyration R. The bigger the better as far as possible, so that can pull compact boom, operating small space]21[.3.2 The selection of pull arm cylinder and cylinder installation angle y. The range ofDetermined by the following two aspects:a. By mapping method or analytical method to determine the location of the above the hinge pivot and Pull arm geometry and other components, may initially determine the pull-stroke arm cylinder and installation distance.b. Pull arm cylinder mounting angle of La Boom is the important structural parameters of devices. By the former knowledge, pull the boom box or device for carrying out the process of dumping action, pull the oil boom cylinders have to be overcome trunk (full load) resistance torque generated by gravity, and the lifting crane action start unloading boxes when the moment of resistance is the greatest moment of resistance to overcome, and in Boom began pulling action of the hinge pivot device static friction and inertia moment of resistance Maximum torque. So pull arm cylinder mounting angle y. From the previous analysis we know, when angle larger, the pull arm cylinder smaller maximum thrust required, select the pull arm cylinder bore can be smaller.By pulling in the boom cylinder is installed between the frame and trunk floor, oil cylinder installation layout space is limited, so the pull arm cylinder mounting angle range is also very limited. Design principles to children as much as possible to install a large angle, choose the right drawing arm oil pulling arm cylinder bore to meet performance requirements for the use of vehicles, without increasing the cost and fuel tank weight, and easy layout. Analysis and comparison of some domestic manufacturers to produce 5 t pull arm ,the actual design and production of cars and trucks pulling arm experience, 5 t pull arm around the installation space vehicles between 250 ~ 300 mm, the general tension arm cylinder mounting angle should be Taken between 3°~5°.附录B拉臂式垃圾车设计1拉臂车概述拉臂式垃圾车是在二类汽车底盘上装有使车箱具有装载和卸载功能的拉臂架装置的专用汽车。

附录The new high pressure cleaning the carWith the rapid development of industry, environment pollution is becoming more and more serious, the environmental protection question is already a global strategy. In order to adapt to the needs of the construction of urban environmental sanitation, clear in time the city, improve air quality, sanitation vehicles of development and development, has become an important topic of the set before us. The development of urbanization in our country, the increase of the road to the requirements of environmental protection and improve, which makes the sanitation car requirement increasingly, high pressure cleaning the car as a sanitation in vehicles, having to clean the road, guardrail and purify airy action, is one of the important urban environmental protection equipment. The current domestic production of high pressure cleaning car backward in technology, there are many problems; Foreign cleaning vehicle performance while is superior, but the price is expensive, need a lot of foreign exchange, it is not the solution to the problem. Therefore, the development of new high pressure cleaning cars has become China's urban environmental protection work important problem to be solved. It not only with independent intellectual property rights, and can improve the design level of our country special automobile, driving the sanitation vehicles in China to develop and manufacture independent design ability.1 a general introductionHigh pressure cleaning cars mainly by the power system, water system and hydraulic system, electronic control and manipulate system components. Power system for cleaning the car to walk and water pumps provide motivation. Water system mainly by the high pressure pump, water tank, valve, nozzle and other components, water through the pump pressure can improve after to 8 MP, form high pressure jet spraying to road, effectively flush the sand dust. Hydraulic system mainly by the hydraulic pump and motor and and valve set and other components, control vehicle to walk and injection action. Electric control part by sensors, SCM and maindisplay control panel etc. In this paper the development of high pressure cleaning car main technical parameters are as follows:The rating capacity; Engine output power 45 KW; The biggest water spray width is not less than 3 m; Spray work for vehicle speed 5 km/h; Spray water pressure is not less than 8 MP; Total number of nozzle 21; Water pump water largest amount 65km/h.2 power distribution and switching system2.1 the basic principle of the power transmission and scheme selectionHigh pressure cleaning car according to the function of the realization of the divided into two kinds of state: a normal work is driving condition, high pressure cleaning the car and general at the same car, realize the transfer function; vehicle 2 it is watering operations state, the state in the vehicle with very low, the speed of the high pressure water spray homework, cleaning the road. Due to the high pressure cleaning the car need driving and driven two aspects of the pump power, so the dynamic how to provide design is to consider when the primary issue.At home and abroad and usually use the power distribution solutions has two, one is to adopt double configuration of the engine power transmission system, is main engine vehicles not alter, transmission system will not do change, use a Taiwan independence in vehicles outside the system of power auxiliary engine drive hydraulic system for high pressure pump provide motivation.The advantages of this scheme is simple in structure, the price is low, the disadvantage is as the vehicle in the water spray work driving the speed, low speed less than 10 km/h, this time the main engine can't work in the best working point, that power allocation is not reasonable, can produce fuel and power waste, and occupy the space of vice engine body, less the water storage volume, vice vehicle engine installation added new vibration noise sources, the influence the stability of the vehicle.Another plan is to use the vehicle engine vehicle transmission system and hydraulic system provide the power, through the points with FenDongXiang action, in the transfer road, driven by the main engine FenDongXiang to driving axledifferentials, high speed movement; vehicle In injection homework road, driven by the main engine FenDongXiang to hydraulic system, on the one hand, control operation speed, on the other hand, the drive pump water spray.The scheme with the foregoing scheme, its advantage is compared, giving full play to the engine power, make the vehicle in the water spray operations can still working at high speed rating of the work of the state, not only save one engine, reduce the fuel consumption, and engine exhaust emission index is more advantageous to achieve urban environmental protection requirement. The vehicle structure more reasonable, vehicle weight of low, water storage space increases. To sum up, single engine configuration is a more reasonable configuration, so this paper power in the new, high pressure cleaning vehicle design, using a single engine design scheme.2.2 power distributionTo ensure the high pressure pump provide of the injection pressure is constant, drive the hydraulic loop quantitative hydraulic pump must work in constant speed rating of the work of the state, water spray operations vehicle of the speed and the road of injection effect is also not to change about the amount of driving, so drive the variable pump will work in constant speed rating of the work of the state, the consumption of driving power also for setting value. Thus, when the engine power to homework for setting value.2.3 new single axis FenDongXiang designFenDongXiang power distribution is the core of the system, the traditional thought of design FenDongXiang usually adopts two to three axis structure of power distribution. This paper introduces the design of new light high-pressure cleaning vehicle USES the chassis is isuzu NKR55LLA light chassis, with traditional structure of the FenDongXiang sizes too large, can't meet the size requirement. According to the characteristics of the power distribution system, independent design and development of the single shaft driving, the FenDongXiang greatly reduced the FenDongXiang size, make body structure more compact.3 hydraulic systemThe hydraulic control system is watering operations every action when the key to meeting, and the main variable pump, the quantitative pump, the drive motors, hydraulic cylinder, cooler, integrated control valves piece, filter etc. From the function of the realization of the perspective, hydraulic system by hydraulic motor drive travel system and hydraulic pressure motor drive water spray system twosub-systems.3.1 hydraulic motor drive driving systemThe variable pump, hydraulic motor and the corresponding hydraulic loop hydraulic subsystem, a walk for the system for oil pump, and quantitative pump coaxial connected. This system consists of integrated control valves to realize the control of hydraulic pump and hydraulic system. The variable pump and motor selection, according to the basic power to determine the value.3.2 hydraulic motor drive water spray systemHydraulic motor drive water spray system by quantitative pump, quantitative hydraulic motor, water pump, relief valve, cooler, filter and hydraulic cylinder and stacked valves group etc. For the hydraulic cylinder and stacked valves group together, for the control of water spray frame lift, extendable such action. The hydraulic oil tank, passes through to return to cooler water.4 water injection systemThe water system is high pressure cleaning the car mainly by the core part high pressure water pump, water spray nozzle, frame, the spray gun and valve etc. Water tank flow of water out of the pump will improve after water pressure to 8 MP, form high pressure jet spraying to the road. The high pressure pump rational selection of engine efficiency, the best utilization, best flush efficiency have important influence, need according to the design requirements and engine parameters, such as to determine the high-pressure pump power, speed and the parameters such as pump pressure at work. Water system design of the main problems including the following two aspects.4.1 the telescopic multi-degree-of-freedom water spray frameWater spray frame is injection system of actuators, installed in high pressure cleaning car head, high pressure water spray nozzle in the frame. To increase the width of the jet wash, design the new hydraulic control expansion institutions. Work, install a nozzle two of the rear protruding from the front of the car, and the nozzle into a straight line, and the high pressure water jet to; After completion of work, back to the nozzle tube retract side. Water spray frame from ground level also controlled by hydraulic system, also designs of the mechanical structure, highly fine-tuning height adjustment to trace.4.2 water spray system parameters optimizationHigh pressure cleaning the car is the purpose of the quality of the road surface cleaning out clean, so, how to improve the cleaning effect, water conservation is design to consider when important question, also is the past studies the problem of no point to consider. The effect of road surface cleaning and many parameters. Including injection height, the shape of the nozzle, injection pressure, injection Angle, jet width, nozzle diffusion Angle, distance of the nozzle. Through a lot of the theoretical and experimental research, to determine the height of the injection pressure injection, jet Angle, the width of the jet, the nozzle of the diffusion Angle of pavement, wash the best results, the wash rate in above, clean unit area of the pavement, the consumption of water and energy, reached the best matching value.5 electronic control and operation system designElectronic control system to realize the working state of the vehicle display, monitoring, alarm and control etc. Function. Mainly includes the instrument shows system, dashboard, the hydraulic oil drive speed dial, hydraulic oil temperature display, hydraulic display, water tank water of the display and alarm, PenShuiGuan working status display, hydraulic system running time records, and other functions, the whole system USES modular design, the control panel integrated in driving indoor proper place, facilitate the operator control operation.The water tank of the monitoring and forecast of electric control system is the important link, must be strictly controlled. Tank water after cooler for hydraulic oil after cooling to enter high pressure pump and so have a water tank must be reserved to the amount of water. In the the design of the magnetic levitation type level sensor,accurately measure the level of height. Control system mainly including operation box, the power switch handle, oil, left, pedal drove speed, PenShuiGuan right control handle, water spray handle adjustable control handle to and fro and speed of the pedals. The design of the control system, the arrangement of the operation box, structure, the handle position, fully considered the man-machine engineering requirements, easy to control.6 general structure designOn the structure, the vehicle including chassis (with cab), water tank, hydraulic oil tank, water pump, FenDongXiang, water spray rack large components.

Johannes PretoriusAbstractIn this report we discuss the specification, analysis and verification of an automated parkinggarage in mCRL2, a process algebra with data. We view the parking garage as a system that weconceplually divide into three layers: a logical layer, a safety layer and a hardware abstractionlayer. This allows us to abstract from implementation details (hardware abstraction layer) andalgorithm design (logical layer). Instead, we are able to focus on the specification of acommunication interface between these two layers that only allows safe system behavior. Thisinterface constitutes the safety layer. For the safety layer, we identify and fonnuiate a number of requirements. These are verified and reported on. We also discuss the analysis of the specificationof the safety layer with a simple custom visualization tool. This tool was implemented as a plug-in to the mCRL2 toolset and helped us gain important insights during the specification andanalysis of the safety layer.1IntroductionDuring the past two decades process algebras have become increasingly popular tools fordescribing complex systems that interact with their environment (5]・ Such systems differ fromclassic batch processes that receive input, process the input, preduce output and then terminate. Instead, their behavior is continuously influenced by information that they receive from their environment. An automated p arking garage is a p rime exam pie of such a system. It is in op eration24 hours a day, 7 days a week; it is continuously on standby, ready to stowaway and retrieve carsfor users. Furthermore, the state of the garage is constantly changing as cars are added andremoved. At any p oint in time, this state influences which op erations are possible and how theyare executed.Process algebra allows for high-level descriptions of systems that interact with theirenvironment. A system is regarded as a number of interacting processes that together describe its behaviour. In this way a mathematical model is acquired and this is used to prove variousProperties of the system using mathematical proof techniques. The process algebra used in this report is mCRL2 [3]. It succeeds and extends pCRL [4, 5].With pCRL a large number of real-world systems have been analysed and verified- Some of the successes that pCRL has booked include the detection of an unknown deadlock in the most complex variant of the sliding window protocol [L 11], the identification of a number of errors in a distributed lifting system for trucks [2] and the discovery of two errors in a Java distributed memory impleinentation [9]. From all these experiinents we unfortunately have had to formulate the 100% rule: in 100% of the cases considered, systems turn out to contain more or less serious errors, which are not very hard to detect.An important characteristic of mCRL2 and its predecessor pCRL is the inclusion of data .Experience has shown that in real-world systems data is of parainount importance [6]. In addition to the execution of actions, it is often the case that data is stored and communicated, thus having a significant influence on system behaviour.In the remainder of this report we discuss the specification of an automated parking garage in mCRL2・ We also discuss the analysis and verification of the system and the techniques used. In section 2 we provide more details on the challenges presented by this system. In section 3 we outline the approach we have taken to address these issues and we explain how we conceplually divide the system into three layers. This allows us to concentrate on one layer, the safety layer.which we believe is essential in verifying that the system is safe. We follow this by a discussion of mCRL2 and the mCRL2 toolset in section 4. In sections 5, 6 and 7 we specify the hardware abstraction layer, the safety layer and the logical layer respectively. We treat the hardware abstraction layer and the logicallayer tersely but reveal more details of the safety layer: we provide a specification, formulate a number of safety requirements and verify these. In section 8 we describe a simple visualization plug-in for the inCRL2 toolset as well as the insights we gained from using it. Finally, we draw conclusions in section 9.2Problem descriptionThe parking garage that we are concerned with was commissioned by developers in Bremen,Germany and was designed by the Dutch comp any CVSS Automated Parking Systems. It will be realised below street level in the basement of an existing building. Access to the garage will beprovided with a vertical lift shaft that has a doorway at street leveL To use the facility, users will drive their car through this doorway into the lift. After they have exited from their car and the lift.their car will automatically be lowered to an intermediate level, rotated 180。
