MSC.1-Circ.1353 - Revised Guidelines For The Preparation Of The Cargo Securing Manual (Secretariat)
PREAMBLE 1 In accordance with the International Convention for the Safety of Life at Sea, 1974 (SOLAS) chapters VI, VII and the Code of Safe Practice for Cargo Stowage and Securing (CSS Code), cargo units, including containers shall be stowed and secured throughout the voyage in accordance with a Cargo Securing Manual, approved by the Administration. 2 The Cargo Securing Manual is required on all types of ships engaged in the carriage of all cargoes other than solid and liquid bulk cargoes. 3 The purpose of these guidelines is to ensure that Cargo Securing Manuals cover all relevant aspects of cargo stowage and securing and to provide a uniform approach to the preparation of Cargo Securing Manuals, their layout and content. Administrations may continue accepting Cargo Securing Manuals drafted in accordance with Containers and cargoes (BC) – Cargo Securing Manual (MSC/Circ.385) provided that they satisfy the requirements of these guidelines. 4 If necessary, those manuals should be revised explicitly when the ship is intended to carry containers in a standardized system. 5 It is important that securing devices meet acceptable functional and strength criteria applicable to the ship and its cargo. It is also important that the officers on board are aware of the magnitude and direction of the forces involved and the correct application and limitations of the cargo securing devices. The crew and other persons employed for the securing of cargoes should be instructed in the correct application and use of the cargo securing devices on board the ship.

2022考研英语阅读德国汽车生产商German carmakers德国汽车生产商Stuck in third稳居第三Daimler is set to keep chugging down the Autobahnbehind BMW and Audi奔驰意欲一举赶超宝马奥迪AS A corporate motto, The best or nothing has a timeless quality.作为戴姆勒公司的座右铭,唯有最好彰显着一种永恒的品质。
Gottlieb Daimler pasted it on the wall as he went about inventing the modern car in the late19th century.十九世纪晚期,当戈特利布戴姆勒着手创造现代汽车的时候,他将这句话贴在墙上。
In 20xx the firm that bears his name adopted it as a slogan.20xx年,这个以其创始人名字命名的公司将这句话作为广告语。
It was as badly timed as a misfiringengine. Mercedes-Benz, Daimler s car division, already trailing BMW in terms of sales andprofitability, saw another Geman premium carmaker, Audi,also start to pull away in thesame year.作为一个正走下坡路的公司,这个口号来的有点晚。
在销量、盈利方面,戴姆勒旗下的奔驰都已双双落后宝马。
同期,德国另一高档汽车制造商奥迪也开头将奔驰甩在身后。
Yet this year Daimler s shares have surged by 40%, persuading optimists that the firm iscatching up.然而,今年戴姆勒公司的股价涨幅高达40%,乐观人士开头认为正确而不怀疑该公司正逐步赶上。

The Design Document Design phase deliveries
The Design DocumentDesign phase: deliveries•Main delivery: design documentDesign = an activity that gives structure to the solution to a given problem •the design phase starts with the requirements document and maps the requirements into architecture•the architecture defines the components, their interfaces and behaviors•the design document describes a plan to implement the requirements•details on computer programming languages and environments, machines, packages, application architecture, distributedarchitecture layering, memory size, platform, algorithms, datastructures, global type definitions, interfaces, and many otherengineering details are established•may include the usage of existing componentsDesign document template (1)•Introduction•System Overview •Design

intended audience–Identify the system/product using any applicable names and/or version numbers.–Provide references for any other pertinent documents such as: •Related and/or companion documents•Prerequisite documents•Documents which provide background and/or context for thisdocument•Documents that result from this document (e.g. a test plan or adevelopment plan)–Define any important terms, acronyms, or abbreviations–Summarize (or give an abstract for) the contents of this document.Design document template (3)•System Overview–Provide a general description of the software system:•functionality and•matters related to the overall system and its design•[discussion of the basic design approach or organization] •Design Considerations–describes many of the issues which need to be addressed or resolved before attempting to devise a complete design solution •Assumptions and Dependencies–Describe any assumptions or dependencies regarding the software and its use:•Related software or hardware•Operating systems•End-user characteristics•Possible and/or probable changes in functionalityDesign document template (4)•General Constraints–global limitations or constraints that have a significant impact on the design:•Hardware or software environment•End-user environment•Availability or volatility of resources•Standards compliance•Interoperability requirements•Interface/protocol requirements•Data repository and distribution requirements•Security requirements (or other such regulations)•Memory and other capacity limitations•Performance requirements•Network communications•Verification and validation requirements (testing)•Other means of addressing quality goals•Other requirements described in the requirements specificationDesign document template (5)•Goals and Guidelines–goals, guidelines, principles, or priorities which dominate or embody the design of the system's software:•The KISS principle ("Keep it simple stupid!")•Emphasis on speed versus memory use•working, looking, or "feeling" like an existing product –for each such goal or guideline, unless it is implicitly obvious, describe the reason for its desirability•Development Methods–describe the method or approach used for this software design –include a reference to a more detailed description of formal or published methodsDesign document template (6)•Architectural Strategies–decisions and/or strategies that affect the overall organization of the system and its higher-level structures–should provide insight into the key abstractions and mechanisms used in the system architecture–the reasoning employed for each decision and/or strategy and how any design goals or priorities were balanced or traded-off•Use of a particular type of product (programming language, database, library, etc. ...)•Reuse of existing software components to implement various parts/features of the system•Future plans for extending or enhancing the software•User interface paradigms (or system input and output models)•Hardware and/or software interface paradigms•Error detection and recovery•Memory management policies•External databases and/or data storage management and persistence•Distributed data or control over a network•Generalized approaches to control•Concurrency and synchronization•Communication mechanisms•Management of other resourcesDesign document template (7)•System Architecture–high-level overview of how the functionality and responsibilities of the system were partitioned and then assigned to subsystems or components –not too much detail about the individual components themselves–main purpose: to gain a general understanding of how and why the system was decomposed, and how the individual parts work together to provide the desiredfunctionality–major responsibilities that the software must undertake and the various roles that the system (or portions of the system) must play–how the system was broken down into its components/subsystems–how the higher-level components collaborate with each other–provide some sort of rationale for choosing this particular decomposition–make use of design patterns–include any diagrams, models, flowcharts, documented scenarios or use-cases of the system behavior and/or structure•Subsystem Architecture–more detailed discussion of particular components–how the component was further divided into subcomponents, and the relationships and interactions between the subcomponents–recurse if necessary, but leave the details for the Detailed System Design sectionDesign document template (8)•Policies and Tactics–Choice of which specific product to use (compiler, interpreter, database, library, etc. ...)–Engineering trade-offs–Coding guidelines and conventions–The protocol of one or more subsystems, modules, or subroutines–The choice of a particular algorithm or programming idiom (design pattern) to implement portions of the system's functionality –Plans for ensuring requirements traceability–Plans for testing the software–Plans for maintaining the software–Interfaces for end-users, software, hardware, and communications–Hierarchical organization of the source code into its physical components (files and directories).–How to build and/or generate the system's deliverables (how to compile, link, load, etc. ...)Design document template (9)•Detailed System Design–detailed description of the components introduced in “System Architecture”chapter–Classification•kind of component, such as a subsystem, module, class, package, function, file, etc. ....–Definition•specific purpose and semantic meaning of the component.–Responsibilities•primary responsibilities and/or behavior of this component:–What does this component accomplish?

奇思妙想折叠汽车作文英文回答:Folding cars? That sounds like something out of a sci-fi movie! But hey, I'm all for innovation and thinking outside the box, so let's explore this idea.Imagine a car that can fold itself up into a compact size, making it easier to park and store. It could be a game-changer for urban dwellers like me who struggle to find parking spaces. Just think about it no more circling the block for hours, no more parallel parking nightmares. With a folding car, I could simply pull up to my destination, press a button, and watch as my car neatly folds itself into a small package.But how would it work? Well, I envision a car with flexible materials and joints that allow it to fold and unfold. Think of it like origami, where the car's body panels and roof can fold inward or outward, reducing itsoverall size. Of course, safety would be a top priority, so the car would need to have sturdy construction and secure locking mechanisms to ensure it stays in place when folded.Now, let's talk about the benefits of a folding car. Aside from the obvious convenience of parking, it could also have a positive impact on the environment. With smaller cars taking up less space on the road, traffic congestion could be reduced, resulting in fewer emissions and a cleaner atmosphere. Plus, imagine the possibilities for car-sharing services or rental companies. They couldfit more cars in their fleets, making transportation more accessible and affordable for everyone.But like any new technology, there would be challenges to overcome. Safety regulations and crash testing would need to be adapted to account for the unique design of a folding car. And what about maintenance? Would it be more complicated or expensive to repair a car with moving parts? These are all factors that would need to be carefully considered and addressed.中文回答:折叠汽车?听起来就像是科幻电影中的东西!但是嘿,我支持创新和超越常规的思维,所以让我们来探索这个想法。

Acura 车辆识别号说明
Identification NumbersYour car has several identifying numbers located in various places.The Vehicle Identification Number (VIN) is the 17-digit number your Acura dealer uses to register your car for warranty purposes. It is also necessary for licensing and insuring your car. The easiest place to find the VIN is on a plate fastened to the top of the dashboard. You can see it by looking through the windshield on the driver's side. It is also on the Certification label attached to the driver's door jamb, and is stamped on the engine compartment bulkhead.The VIN is also provided in bar code on the certification label.Technical InformationVEHICLE IDENTIFICATION NUMBERCERTIFICATION LABELIdentification NumbersThe Engine Number is stamped into the engine block. It is on the front left, below the valve cover.The Transmission Number is on a label on top of the transmission.Technical InformationTRANSMISSION NUMBERENGINE NUMBERSpecificationsTechnical Information*1: Including the coolant in the reserve tank and that remaining in the engine.Reverve tank capacity:0.65 (0.69 USqt, 0.60lmp qt)*2: Excluding the oil remaining in the engine.DimensionsWeightsAir ConditioningCapacitiesSpecifications*1: L,LS models *2 : GS modelTechnical InformationLightsBatteryFusesEngine Alignment Tirespage 223page 224page169Anti-lock Brake SystemThe Anti-lock Brake System (ABS)works by measuring how fast the wheels are turning during braking and comparing their speed. If any wheel is rotating much slower than the others (on the verge of locking up and skidding), the system reduces hydraulic pressure to that wheel's brake caliper. When that wheel's speed matches the other wheels, the system applies normal hydraulicpressure. This can take place several times per second at each wheel. You feel the ABS working as rapid pulsations in the brake pedal.Each wheel has a wheel speed sensor assembly. As the wheel rotates, the sensor sends electrical pulses to the ABS control unit. The pulse frequency varies with the wheel speed.The electrical output of the ABS control unit is connected to the Modulator/solenoid unit. During braking, the ABS control unit moni-tors the pulse frequencies from the four wheels. When the control unit detects a wheel locking up, it ener-gizes the appropriate solenoid in the modulator/solenoid unit. There are three solenoids: one for each front wheel, and one for the rear wheels.The energized solenoid reduces hydraulic pressure to one side of a modulator valve. This, in turn,reduces hydraulic pressure in the brake line going to the affected wheel. When that wheel speeds up because of the reduced braking effort, the control unit de-energizes the solenoid. This builds hydraulic pressure on the modulator valve. The pressure increases in the hydraulic line to the wheel.For the system to react quickly, the modulator/solenoid unit must have brake fluid under high pressure.This is supplied by a diaphragm-type accumulator that is pressurized by an electric pump. A pressure-sensing switch on the accumulator controls this pump.The control unit also contains error detection circuitry. It monitors the operation of the wheel sensors,solenoids, pump, and electronics. If the control unit detects any faults, it shuts off power to the pump motor and solenoids. The light on the instrument panel comes on. Thebrakes then work like a conventional system without anti-lock capabilities.Technical InformationTraction Control SystemThe TCS works on the same speed-sensing principles as the Anti-lock brake system. The TCS monitors the speed of the wheels during accelera-tion. If one drive wheel starts to spin faster than the other, or both drive wheels spin faster than the rear wheels, the TCS reduces engine power to minimize wheelspin.The TCS uses the same wheel speed sensor assemblies used by the ABS.An additional sensor measures steering-wheel-angle. This senses how far the front wheels are turned,if at all. The TCS control unit receives the signals from these sensors.When the TCS senses wheelspin, the control unit determines how much slippage to allow based on thedifference in wheel speeds and the steering angle. It then controls the throttle and signals the engine's ECU (ECM or PCM) to regulate ignition timing and fuel flow. This reduces available engine power.The control unit monitors the TCS circuitry while driving. If it senses a problem, the TCS indicator light on the instrument panel goes on. The system will then be turned off.Technical InformationTire InformationTire Size DesignationA tire's sidewall is marked with a tire size designation. You will need this information when selecting replace-ment tires for your car. The following explains what the letters and num-bers in the tire size designation mean.(Example tire size designation)205/60R15 91V205 — Tire width in millimeters 60 — Aspect ratio. The tire's section height as a percentage of its width.R — Tire construction code (Radial).15 — Rim diameter in inches.91 — Load Index, a numerical code associated with the maximum load the tire can carry.V — Speed Rating Symbol. See the speed rating chart in this section for additional information.Wheel Size DesignationWheels are also marked with impor-tant information that you need if you ever have to replace one. The follow-ing explains what the letters and numbers in the wheel size designa-tion mean.(Example wheel size designation)15 x 6.5 JJ15 — Rim diameter in inches.6.5 — Rim width in inches.JJ — Rim contour designation.Tire Speed RatingsThe chart below shows many of the different speed ratings currently being used for passenger car tires.The speed rating symbol is part of the tire size designation on the sidewall of the tire. This symbol corresponds to that tire's designed maximum safe operating speed.Technical InformationTire InformationTire Pressure Adjustment For High Speed DrivingAcura strongly recommends that you not drive faster than posted speed limits and conditions allow. If you decide it is safe to drive at highspeeds, be sure to adjust the cold tire pressures as shown below. If you do not adjust the tire pressure, exces-sive heat can build up and cause sudden tire failure.(GS)Be sure to readjust the pressure for normal driving speeds. You should wait until the tires are cold before adjusting the tire pressure (see page 179).DOT Tire Quality Grading (U.S. Cars)The tires on your car meet all U.S.Federal Safety Requirements. All tires are also graded for treadwear,traction, and temperature perfor-mance according to Department of Transportation (DOT) standards.The following explains these gradings.TreadwearThe treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tiregraded 150 would wear one and one half (1-1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits,service practices and differences in road characteristics and climate.CONTINUEDTechnical Information(L, LS)Tire InformationTractionThe traction grades, from highest to lowest, are A, B, and C, and they represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.Warning: The traction grade as-signed to this tire is based on braking (straight ahead) traction tests and does not include cornering (turning)traction.TemperatureThe temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled condi-tions on a specified indoor laboratory test wheel. Sustained high tempera-ture can cause the material of the tire to degenerate and reduce tire life,and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109.Grades B and A represent higher levels of performance on the labora-tory test wheel than the minimum required by law.Warning: The temperature grade for this tire is established for a tire that is properly inflated and not over-loaded. Excessive speed, under-inflation, or excessive loading either separately or in combination, can cause heat build-up and possible tire failure.Technical InformationEmission ControlsThe burning of gasoline in your car's engine produces several byproducts.Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC). Gasoline evapo-rating from the tank also produces hydrocarbons. Controlling the production of NOx, CO, and HC is important to the environment Under certain conditions of sunlight and climate, NOx and HC react to form photochemical "smog." Carbon monoxide does not contribute to smog creation, but it is a poisonous gas.The Clean Air ActThe United States Clean Air Act* sets standards for automobile emissions.It also requires that automobilemanufacturers explain to owners how their emission controls work and what to do to maintain them. This section summarizes how the emis-sion controls work. Scheduled maintenance is on page 146.* In Canada, Acura vehicles comply with the Canadian Motor Vehicle Safety Standards (CMVSS) onEmissions valid at the time they are manufactured.Crankcase Emission Control SystemYour car has a Positive Crankcase Ventilation System. This keeps gasses that build up in the engine's crankcase from going into theatmosphere. The Positive Crankcase Ventilation valve routes them from the crankcase back to the intake manifold. They are then drawn into the engine and burned.Evaporative Emission Control SystemAs gasoline evaporates in the fuel tank, an evaporative emission control canister filled with charcoal adsorbs the vapor. It is stored in this canister while the engine is off. After theengine is started and warmed up, the vapor is drawn into the engine and burned during driving.Exhaust Emission Controls The exhaust emission controls include five systems: PGM-FI,Ignition Timing Control, Exhaust Gas Recirculation, Three Way Catalytic Converter and Warm-up Three Way Catalytic Converter or Air Supply System. These five systems work together to control the engine's combustion and minimize the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust emission control systems are sepa-rate from the crankcase and evapora-tive emission control systems.Technical InformationEmission ControlsPGM-FI SystemThe PGM-FI System uses sequential multiport fuel injection. It has three subsystems: Air Intake, Engine Control, and Fuel Control. The Engine Control Module (ECM)/Powertrain Control Module (PCM-AT only) uses various sensors todetermine how much air is going into the engine. It then controls how much fuel to inject under all operat-ing conditions.Ignition Timing Control System This system constantly adjusts the ignition timing, reducing the amount of HC, CO, and NOx produced.Exhaust Gas Recirculation (EGR) SystemThe Exhaust Gas Recirculation (EGR) system takes some of the exhaust gas and routes it back into the intake manifold. Adding exhaust gas to the air/fuel mixture reduces the amount of NOx produced when the fuel is burned.Three Way Catalytic Converter The three way catalytic converter is in the exhaust system. Through chemical reactions, it converts HC,CO, and NOx in the engine's exhaust to carbon dioxide (CO 2), dinitrogen (N 2), and water vapor.Warm-up Three Way Catalytic Converter (GS Model only)This is in the exhaust system, near the exhaust manifold. During engine warm-up, it converts HC, CO, and NOx to carbon dioxide (CO 2),dinitrogen (N 2), and water vapor.Air Supply System (Except GS model)This system supplies more air to the engine during deceleration. This reduces emissions by allowing more complete combustion.Replacement PartsThe emission control systems are designed and certified to work together in reducing emissions to levels that comply with the Clean Air Act. To make sure the emissions remain low, you should use only new genuine Acura replacement parts or their equivalent for repairs. Using lower quality parts may increase the emissions from your car.The emissions control systems are covered by warranties separate from the rest of your car. Read yourwarranty manual for more informa-tion.Technical InformationThree Way Catalytic ConverterThe three way catalytic converter contains precious metals that serve as catalysts, promoting chemical reactions to convert the exhaust gasses without affecting the metals.The catalytic converter is referred to as a three-way catalyst, since it acts on HC, CO, and NOx. A replacement unit must be an original Acura part or its equivalent.The three way catalytic converter must operate at a high temperature for the chemical reactions to take place. It can set on fire any combus-tible materials that come near it.Park your car away from high grass,dry leaves, or other flammables.A defective three way catalyticconverter contributes to air pollution,and can impair your engine's perfor-mance. Follow these guidelines to protect your car's three way catalyticconverter.Always use unleaded gasoline.Even a small amount of leaded gasoline can contaminate the catalyst metals, making the threeway converter ineffective.Keep the engine tuned-up.Have your car diagnosed and repaired if it is misfiring, backfir-ing, stalling, or otherwise not running properly.Technical InformationTHREE WAY CATALYTICCONVERTER。

The Basics of Car Engine Design
The Basics of Car Engine DesignCar engine design is a complex process that involves a variety of engineering disciplines, including mechanical, electrical, and chemical engineering. The engine is the heart of a car, and its design determines how efficiently the car will run and how much power it will produce. In this article, we will explore the basics of car engine design and the factors that engineers consider when designing an engine.The first factor that engineers consider when designing a car engine is the type of fuel that the engine will use. There are three main types of fuel that are used in car engines: gasoline, diesel, and electric. Gasoline engines are the most common type of engine, and they are designed to run on gasoline fuel. Diesel engines are designed to run on diesel fuel, which is a heavier and more viscous fuel than gasoline. Electric engines, on the other hand, are powered by batteries and do not require any fuel.The second factor that engineers consider when designing a car engine is the numberof cylinders that the engine will have. Most car engines have four, six, or eight cylinders, although some high-performance engines may have more. The number of cylinders in an engine determines how much power the engine can produce, with more cylinders generally resulting in more power.The third factor that engineers consider when designing a car engine is the engine's displacement. Engine displacement is the volume of air that the engine can move in a single cycle, and it is measured in cubic centimeters (cc) or liters (L). The displacement of an engine determines how much power the engine can produce, with larger displacements generally resulting in more power.The fourth factor that engineers consider when designing a car engine is the engine's compression ratio. The compression ratio is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke to the volume of the combustion chamber when the piston is at the top of its stroke. A higher compression ratio results in more power and better fuel efficiency, but it also requires higher-octane fuel and can leadto engine knock if not properly tuned.The fifth factor that engineers consider when designing a car engine is the engine's valve train. The valve train is the system of valves, lifters, and pushrods that control the flow of air and fuel into and out of the engine. The valve train determines how much air and fuel the engine can take in, and how quickly it can release exhaust gases. A well-designed valve train can significantly increase the power and efficiency of an engine.Finally, engineers consider a variety of other factors when designing a car engine, including the engine's cooling system, lubrication system, and ignition system. The cooling system is responsible for keeping the engine from overheating, while the lubrication system ensures that all of the engine's moving parts are properly lubricated. The ignition system is responsible for igniting the fuel in the combustion chamber, and it can significantly affect the engine's performance and efficiency.In conclusion, car engine design is a complex process that involves a variety of engineering disciplines. Engineers consider a variety of factors when designing an engine, including the type of fuel, the number of cylinders, the engine's displacement, the compression ratio, the valve train, and the engine's cooling, lubrication, and ignition systems. By carefully considering these factors, engineers can design engines that are powerful, efficient, and reliable, ensuring that cars can provide the performance and reliability that drivers demand.。
从内存中加载并启动一个exe
windo ws似乎只提供了一种启动进程的方法:即必须从一个可执行文件中加载并启动。
而下面这段代码就是提供一种可以直接从内存中启动一个exe的变通办法。
用途嘛, 也许可以用来保护你的exe,你可以对要保护的exe 进行任意切分、加密、存储,只要运行时能将e xe的内容正确拼接到一块内存中,就可以直接从内存中启动,而不必不安全地去生成一个临时文件再从临时文件启动进程。
另外这段代码也提供了一种自己写exe外壳的简单途径,如果能配合其它各种外壳技术就更好地保护你的exe文件。
原理很简单:就是“借尸还魂”,启动一个僵尸进程(N T下可以是自身程序启动的另一个进程),然后在它运行前将其整个替换成内存中的exe内容,待正式运行后执行的就是你的目标代码了。
不过代码中还有一些不尽人意的地方,比如在98下运行会留一个僵尸程序的壳在硬盘上(其实那个僵尸程序本身就是一个完整的可执行程序,直接运行的话只显示一条错误信息然后就退出了)。
另外由于客观条件限制,代码没有经过充分测试,只在X P下进行了一些初步测试:普通e xe都能正常运行,u px压缩过的exe绝大多数情况下都能运行,只有在不能卸载僵尸外壳时才有问题(up x压缩过的exe没有重定向表,无法加载到其它地址运行)。
如果有b ug望告之,如果有更好的方法特别是能解决98下的遗留尾巴的话希望不吝赐教。

2. 系统概述
本系统是一个信号灯的控制系统,它是在FPGA实验平台上实现的,主要用来熟悉汽车信号灯的控制方式,并且可以在实验平台上加入一些自己认为有价值的模块。
系统的主要功能描述如下:
(1) 左/右转弯(合上左/右转弯开关):左/右转弯灯闪烁,对应的仪表灯亮
(2) 紧急开关合上:所有灯闪烁。
(3) 刹车(合上刹车开关):左右尾灯亮。
(4) 左/右转弯刹车:左/右转弯灯闪烁(频率高),左右尾灯亮。
(5) 刹车、合上紧急开关:尾灯亮、其它灯闪烁。
(6) 停靠(合上停靠开关):头灯、尾灯闪烁。
(7) 夜间(合上示宽开关):左/右示宽灯亮。
(8)复位开关:所有灯灭(初始状态)。
3. 设计约束
本设计在FPGA实验平台上实现,因此所设计的模块必须与实验平台相对应。
设计所用的程序用Verilog HDL语言来编写。
初步准备将程序得用QUARTUS II软件来综合,利用Modelsim软件来进行仿真。
4. 设计策略
我们的设计工作主要分为两个阶段,首先是系统仿真功能的实现,这也是一个基本阶段,就是实现在实验板上对相应的信号灯进行控制。
其次是优化阶段,因为目前的信号灯控制系统都是基于人工操作的,但是在一些情况下难免会发生意外,例如,我们有些时候会忘记相应的操作,这样难免会给其它的驾驶员发出错误的信号,造成不好的结果。
因此在优化阶段我们会考虑是否可以用系统代替人来完成转向灯控制的操作。
如果得到了这样一种方法,我们就可以在第一阶段的基础上来进行测试。
因为它只是代替了人工操作这一环节,因此可以直接利用第一阶段完成程序来测试结果。
5. 系统总体结构
系统主要包含三个子模块,主要的是控制模块,也就是用来处理接收到的操作信息,然后再将控制数据传输出去。
接下来是操作模块,它用来输入操作员想要实现的功能。
显示模块是对操作的反馈,说明系统是否成功实现。
这三个模块全部在FPGA开发板上,利用开发板的电路来完成系统。
在对系统上电以后首先进行的是复位的工作,复位后的系统直接进入查询模式,就是查询对应的输入有没有变化,也就是查询键盘有没有出现高电平或者上升沿,如果没有出现的话那么就进行一个空操作,继续查询输入的设备有没有操作。

系统分解视图
当按下一个按键时,也就是对系统作出了一个操作,那么由系统扫描8个键盘的输入信号电平,然后传送到控制芯片中,在控制芯片中对相应的输入状态进行比较,比较的对象是已经存储在芯片中的状态(因为本电路就涉及8个状态,因此可以利用比较的方法来设计)。
将比较的结果转化为相应的输出来驱动LED 二极管来显示结果。
实现视图如下所示:
系统的实现视图
例如操作员只按下了按键3,那么就会向系统提出一个中断请求,由系统响应中断并扫描键盘阵,因为只按下了一个键,则扫描得到的结果就是00001000(设高电平为1,低电平为0,如果按键按下,则对应的位就为高)。
系统将扫描的结果合成一个数组,与存储的状态(也是8位的数组)进行比较,然后选择正确的状态后将结果传送给输出(显示模块)。

6. 开发环境的配置
系统在FPGA实验平台上开发,要用到的主要实验板就是ML505 Evaluation Platform,如下图所示,程序仿真和综合我们利用QUARTUS II和Modelsim相结合来完成,因为Modelsim有很强大的仿真功能,在仿真这一环节能够很好的测试程序,但它不具备综合功能。
因此将它们综合起来使用,互相补充,可以达到很好的效果。
