【摘要】 汽车行驶记录仪是全面记录汽车在行驶过程中的运行速度、时间、里程及其安全信息的基础设备,是促进和提高我国交通管理执法水平和运输管理水平的重要手段。它的推广和使用可为交通安全部门对车辆安全的监督和管理提供方便与支持,因此,具有一定的研究价值。但就目前的发展状况来看,汽车行驶记录仪中数据的获取主要是通过有线传输的方式,这就使得交警在道路执法过程中,很难实时获取行进中车辆的行驶数据,从而也就不能及时有效的制止超时和超速驾驶。为了改变这一现状,本文设计并实现了一种可通过无线方式快速获取汽车行驶记录仪违章数据的检测系统。该系统通过在硬件层面为汽车行驶记录仪添加GPS模块和GPRS模块,使其具有了实时定位和无线数据传输功能。而专门为该系统设计的具有Web发布和数据存储功能的数据控制中心,则能很好的通过GPRS无线通信的方式,接收并存储从汽车行驶记录仪发送来的详细数据。同时,该数据控制中心也能以同样的方式,实现对交警手持终端数据检索请求的接收,以及违章数据的返回。最后经过实验室环境下的测试验证,该检测系统能够实现远程、快速、准确的获取汽车行驶记录仪中的违章信息,达到了预期目的。更多还原

【Abstract】 Vehicle traveling data recorder is a basic device which can be used for a comprehensive record of the vehicle’s running velocity, time, distance and its safety information. And it is an important means to promote the traffic management and transportation management level. The promotion and use of the vehicle traveling data recorder, making the ministry of transportation is more convenient for the supervision and management of the vehicle. Therefore, it has a certain research value.According to the current situation, cable data transmission is the main way of getting the data in vehicle traveling data recorder. This makes it difficult for the traffic police to have timely access to the vehicle data and, thus, can not be effective to stop the timeout and speeding.In order to change the situation, this paper proposes the design and achievement of a wireless detection system which can speedy read the traffic violation information of vehicle traveling data recorder. With the integration of GPS chip and GPRS chip in hardware, this system realizes the new functions of the recorder:real-time location and data upload wirelessly. And for the specially designed web-database, it can excellently receive and storage the detailed information from vehicle recorder through GPRS. In the same way the database can receive data retrieval requests from handhold terminal of the police, and return the violation information. Finally, after the test validation in the laboratory environment, the detection system can quickly get accurate information about the illegal behaviors even in long distance.更多还原
