基于OBD的车联网监测系统
|
摘要
车辆状态信息监测有助于及时发现车辆故障,对车辆进行检修,减少交通事故的发生。为改善当前车辆状态信息监测设备存在的体积大,价格昂贵的现状,研发一款基于OBD的车联网监测系统。设计了OBD-Ⅱ协议转换模块读取汽车ECU状态数据,设计了振动检测模块实时监测行车状态;使用GPRS通信技术将状态数据实时报送到云端,搭建了B/S架构下车联网监测系统网页,接收并显示车辆状态信息。将设备安装到汽车上进行测试,记录行驶过程中的实时油耗和驾驶习惯数据等,描绘车辆行驶的路线,能够满足对车辆的远程监测要求,具有较好的稳定性和一定的实用性。
Vehicle condition information monitoring helps to detect vehicle faults in time,repair vehicles and reduce traffic accidents. In order to improve the current status that vehicle status information monitoring equipment is either too large or expensive,a vehicle network monitoring system based on OBD is developed. The OBD-Ⅱ protocol converting module is designed to read the state data of vehicle ECU. The vibration detection module is designed to monitor the driving condition in real time. The GPRS communication technology is used to send state data to the cloud in real time. The webpage of the networked monitoring system is set up based on B/S framework. It is designed to receive and display the state information of vehicles. At last the equipment is installed on the car for testing. It recorded real-time fuel consumption and driving habits data,depicted the route of the history. It can meet the requirements of remote monitoring of vehicles,and has good stability and practicality.
