（车辆跟踪系统: VTS）

车辆跟踪系统是一种用于跟踪移动车辆的跟踪软件。安装在车辆上的跟踪装置会登录到车辆跟踪系统，并且将定位信息发送给车辆跟踪系统。

The VTS is a piece of tracking software which will be used to track vehicle moving. A VT, which is installed in a vehicle, will login into VTS and send location info to VTS.

这一模块从位置信息收集系统接收逆指令，指令会进入出队列模块。

This component will receive reverse commands which come from LCS, and these commands will be put into the outQueue.

车辆跟踪系统是通信服务器和位置定位处理服务器。车辆跟踪系统从车辆跟踪器接收位置信息定位数据，能够同时监控1000台车辆。协议在车辆跟踪系统中进行处理。

VTS, is the communication server and location process server. VTS get location record sent form VT, and can watch 1000 vehicles in the same time. The protocol is handled in VTS.

此设计文档主要描述车辆跟踪系统的软件架构、模块设计、数据流和功能接口。

Get location record from VT by opened T-TCP connection;

会话管理器是管理所有车辆跟踪器－车辆跟踪系统传输控制协议通信会话的工作线程。Session Manager is a working thread which manages all VT-VTS TCP communication sessions.

存在两种位置信息收集系统连接模式：长连接模式和多连接模式。目前，车辆跟踪系统使用缺省的多连接模式。

There are two LCS connection modes: Long-Connection mode and Multi-Connection mode. Currently, VTS uses the default Multi-Connection mode.

位置信息收集系统有时会通过车辆跟踪系统向车辆跟踪器发送信息。此时仅向车辆跟踪器发送C0和M0信息。若位置信息收集系统通过车辆跟踪系统向车辆跟踪器发送指令，则位置信息收集系统通过车辆跟踪系统获取来自车辆跟踪器的命令正确应答信息。（2分）Sometimes, LCS will send message to VT via VTS. Only C0 and M0 message will be sent to VT. If LCS sends command to VT through VTS, LCS will expect ACK back from VT through VTS.

Please translate these Chinese sentences to English.

除首字母需大写外，类名和变量名定义方式基本相同，例如：Robot。

Class names will be documented in the same way as variable names, except that the first letter must be a capital letter, for instance: Robot.

2．文档使用超文本链接标示语言。文档由多个编辑器以及Macromedia Dreamweaver MX 超文本链接标示语言编辑器生成。

For our documentation HTML is used. Documentation is produced with several editors and Macromedia Dreamweaver MX which is an HTML editor.

3．应用编程接口中所有针对机器人的详细信息都由此组件提供给程序的其余部分。为了接收信息，任何连接到软件的外部资源必须作为观测程序向Robot 类进行自身报告。（2分）All robot-specific information of the API is provided to the rest of the program from this component. Any external resources to the software must report itself to the Robot class as an observer in order to receive information.

4．Robot类控制组件间以及组件和外部资源间的信息流。Subject类控制机器人相关信息发送处。Setpoint类和Position类是包含通过应用编程接口传送并使用机器人坐标的调整点以及使用笛卡尔坐标的位置的容器类。（3分）

The Robot class, which controls the information flow between the components and between the components and the external resources.

The Subject class, Which exists to regulate where information about the robot is sent.

The Setpoint and Position classes, which are container classes with which setpoints in robot coordinates and positions in Cartesian coordinates may be communicated across the API.

5．若实体(Robot类)状态改变，则Observer类及其子类交互。此外Robot 类应用driver类获取机器人位置以及初始化和停止机器人。

The observer class and its children react if the state of the subject (Robot class) changes. Furthermore the driver class is also used by the Robot class to get the position of the robot and to initialize and halt the robot.

6．此组件中的所有数据处理都分配给了其它组件。此组件获得请求之后从其它组件获取该请求的应答。在组件3中完成对Setpoint类的处理，在组件2中存储机器人相关信息。（2分）

All processing in this component is distributed to other Components. This Component gets a request and gets the answer of that request from another Component. The processing of Setpoints is done in Component 3 and information about he robot is stored in Component 2.

Please translate these Chinese sentences to English.

1．文件名可以是长于8个字符的大写字母和小写字母的组合。文件名必须尽可能清晰地反映文件的内容。

The name of files can be more than eight characters, with a mix of upper cases and lower cases. The name of files should reflect the content of the clearly as possible.

2．类成员功能名沿袭Java命名惯例。功能名是单词串的连接，除第一个单词首字母不大写外，其余单词首字母均大写。例如：isMemberSet，printReport，consume。

Class member functions follow Java conventional naming. The function name is a concatenated string of words with the first letter of all words capitalized except for the first one. For example: isMemberSet, printReport, consume.

3．从既不是类也不是命名空间的动态链接库文件导出的函数必须包含此模块名的大写字母缩写词。例如：DEBUGTrace 或DBGTrace.

Functions exported from DLLs, that are not in a class or a namespace should include an uppercase abbreviation of the module name. For example: DEBUGTrace or DBGTrace.

4．对于过程名来说，使用一个强动词加上一个对象。功能内聚的过程通常在对象上执行操作。过程名必须反映过程所做的事情，在对象上的操作意味着动词+对象的名称。printReport()，calcMonthlyRevenues()，和repaginateDocument()都是很好的过程名的例子。

For a procedure name, use a strong verb followed by an object. A procedure with functional cohesion usually performs an operation on an object. The name should reflect what the procedure does, and an operation on an object implies a verb-plus0-object name. printReport(), calcMonthlyRevenuse(), and repaginateDocument() are samples of good procedure names.

5．避免无意义或毫无意义的动词。有些动词词义灵活，可以延伸到表达任何意思。类似handleCalculation()，performServices()，processInput()和dealWithOutput()的例程名不能告知例程所做的事情。这些名称至多说明例程做了某些计算、服务、输入和输出。除非当动词“handle”用在处理某一事件的特定技术环境中。

Avoid meaningless or wishy-washy verbs. Some verbs are elastic, stretched to cover just about any meaning. Routine names like handleCalculation(), performServices(), processInput(), and delWithOupput() don’t tell you what the routines do. At the most, these names tell you that the routines have something to do with calculations, services, input, and output. The exception would be the verb “handle” is used in the specific technical sense of handling an event.

根据经验，包含类的定义及实现的文件应该只包含一个类。这种文件名必须和类名一致。当使用内部类或者私有类时，文件可以包含多个类。

As a rule of thumb, files containing class definitions and implementations should contain only one class. The name of the be the same as the name of the class. Files can contain more than one class when inner classes or private classes are used.

因为模块之间有潜在的冲突，所以必须特别关注头文件命名。如果有需要的话，文件名可添加模块前缀。例如，如果两个模块：数据库和窗口拥有一个无用单元收集程序类，文件可以命名为“DBGarbageCollector.H”及“WINDOWGarbageCollector.H”。

Special care should be given to the naming of header files because of potential conflicts between modules. If necessary, a module prefix could be added to the . For example, if two modules have a garbage collector class: Database and Window, the files could be named: “BDGarbageCollector.H”and “WINDOWGarbageCollector.H”

对于函数名来说，使用对于返回值的描述。函数返回数值，此函数必须针对其返回数值来命

名。例如，cos()，nextCustomerID()，printerReady()和currentPenColor() 都是准确指出函数返回值的很好的函数名例子。

For a function name, use a description of the returns value. A function returns a value, and the function should be named for the value it returns. For example, cos(), nextCustonmerID(), printerReady(), and currentPenColor() are all good function names that indicate precisely what the functions return.

变量名是单词串的连接，除第一个单词首字母不大写外，其余单词首字母均大写。选择的名称必须清晰地表示变量的含义。例如：windowHandle，eventConsumed和index。Variable names are a concatenated string of words with the first letter of all words capitalized except for the first one. The name chosen should clearly represent the content of the variable. For example: windowHandle, eventConsumed, index.

文档注释，尤其在Java中，用于说明类、接口、构造函数、方法和域。每一文档注释都置于注释界定符/**...*/中，每一类、接口或者成员都有一个注释。此注释必须出现在声明之前：Documentation comments, specially in Java, describe the classes, interfaces, constructors, methods, and fields. Each documentation comment is set inside the comment delimiters /**….*/, with one comment per class, interface, or member. This comment should appear just before the declaration:
