【摘要】：随着城市交通的快速发展，多种车辆都开始向智能交通系统（ITS）的方向发展，校车就是其中之一，我国校车管理条例提出要合理规划校车的线路和站点，加强校车的安全管理，提高校车服务。大学城中接送教师的校车往返于市区与大学城之间，怎样使教师在整个上下班过程中花费时间最短、资源利用最少已经成为一个不可小觑的问题。本文针对上述校车存在的问题，研究主要从两个方面来解决。第一是实现校车线路的优化，通过K-Means算法对校车要停靠的站点进行区域划分，再利用改进的蚁群算法对每一个区域进行区域的线路优化，从而优化了原有的校车线路；第二建立校车管理系统，加强校车的监管和调度管理，使乘客、司机和调度人员之间能实现信息共享，保证校车能有效调度管理。校车管理系统主要有车载装置，短信接收发送装置，服务器调度软件组成。三个部分是相铺相成，共同构成了校车管理系统。车载装置在车辆行驶过程中通过GPRS网络实现GPS信息的传输，把信息发送给服务器。车载装置的设计包含硬件、软件和结构设计。硬件由ARM处理器、GPS模块、GSM/GPRS模块、触摸屏模块、GPS天线、GSM天线等组成；软件中涉及了GPRS通信、UC/OS-II和UCGUI的移植等；最后完成机械结构的设计。短信接收发送装置是通过串口连接服务器，输入和输出信息，利用SIM卡和GSM模块来接收乘客发送的信息，再回复车辆位置信息给乘客。在车载装置的模块的基础上，选择了适合的模块和元器件，完成装置的电路设计，实现装置的通信功能。服务器调度软件是校车管理系统的核心控制部分，所有校车的调度管理和定位监控都由服务器调度系统来实现。在软件设计过程中，根据软件功能要求完成数据库表的设计；再完成软件的串口和GPRS接口设计，实现信息的接收和发送；最后设计软件的主界面的功能单元，如GIS地图，，车辆信息管理等。
[Abstract]:With the rapid development of urban traffic, a variety of vehicles are beginning to develop in the direction of Intelligent Transportation system (its). School bus is one of them. Strengthen the safety management of the school bus, improve the school bus service. The school bus to and from the university city between the city and the university city, how to make teachers spend the shortest time in the whole process of commuting to and from work. The use of resources at least has become a problem that cannot be underestimated. This paper aims at the problems of the above school bus, mainly from two aspects to solve the problem. The first is to achieve the optimization of the school bus line, through K-Means algorithm to the school bus to park the station division. Then the improved ant colony algorithm is used to optimize the route of each area, so as to optimize the original school bus line. The second is to establish the school bus management system, strengthen the school bus supervision and scheduling management, so that passengers, drivers and dispatchers can achieve information sharing, to ensure that the school bus can be effective scheduling management. The school bus management system mainly consists of on-board device, short message receiving and sending device, server dispatching software. The three parts are complementary to each other, together constitute the school bus management system. The vehicle-mounted device transmits the GPS information through the GPRS network and sends the information to the server. The design of the vehicle-mounted device includes hardware. Software and structure design. The hardware is composed of ARM processor / GPS module, touch screen module, GPS antenna and so on. The software involves the transplantation of UC / OS-II and UCGUI in GPRS communication. Finally, the design of mechanical structure is completed. The short message receiving and sending device connects the server through the serial port, inputs and outputs the information, and uses the SIM card and the GSM module to receive the information sent by the passengers. On the basis of the module of the vehicle device, the suitable modules and components are selected to complete the circuit design of the device and realize the communication function of the device. Server scheduling software is the core control part of school bus management system. All school bus scheduling management and location monitoring are implemented by server scheduling system. In the process of software design. Complete the design of database table according to the requirement of software function; Then complete the software serial port and GPRS interface design to realize the information receiving and sending; Finally, the function unit of the main interface of the software is designed, such as GIS map, vehicle information management and so on.
