中文摘要: 为了减少高速公路交通事故的发生, 设计了一种能够监控高速公路上车辆行驶状况的系统. 该系统利用GPS采集车辆的行驶信息, 而后通过GPRS将数据传送至服务器, 服务器用特定预警算法对车辆自身以及周围车辆的行驶状况进行判断, 若发现有违规驾驶行为, 则向司机进行自动预警. 在实现系统的同时, 分别对服务器内存资源的调度以及车载终端异常断开的问题提出了改进处理方案. 最后, 在局域网内搭建仿真环境, 对该系统的稳定性、预警事件的处理效率以及预警的准确性进行了测试, 结果表明该系统具有较高的稳定性和预警准确性, 对高速公路监管系统的进一步实现具有很大的参考价值.
Abstract:In order to reduce the traffic accidents in expressway, a system which can monitor vehicles in expressway has been designed. The system uses GPS to collect vehicle information, and then the data be transmitted to sever through the GPRS, a judgement can be made on the vehicle itself and its surrounding running condition with a specific pre-warning algorithm and driver can receive the automatic warning if there are illegal driving behaviors. The improved schemes on memory scheduling of sever and disconnection of vehicle terminals are be respectively proposed. Finally, the stability of system, the processing efficiency of pre-warning events and accuracy of pre-warning are tested in the simulation environment with LAN, the results show that the system has higher stability and accuracy; it can be referred in further studies on the research of monitoring expressway.
