基于车联网的车载智能监测系统设计与实现

Design and implementation of vehicle intelligent monitoring system based on vehicle network

针对目前汽车在车况诊断、防盗等方面存在的不足,设计一款具有车辆故障诊断、防盗预警、定位跟踪等功能的车载智能监测系统。该系统包括车载终端、手机APP、云服务器3部分。构建实时车况监测网络系统,设计车载终端整体框架、高频降压电路以及遵循多种OBD-Ⅱ标准的协议驱动电路。下位机采用线程调度算法并设计实时有效的防盗预警程序;手机APP使用TCP/IP协议与车载终端、云服务器进行信息传输,实时对车辆远程监测。实验结果表明,该系统可以有效实现对车辆的故障诊断、防盗预警。

To solve the defects of vehicles such as fault diagnosis and anti-theft,an intelligent vehicle monitoring system with vehicle fault diagnosis,anti-theft warning,positioning tracking and other functions was designed.The system included vehicle terminal,mobile App and cloud server.A real-time vehicle condition monitoring network system was constructed.The overall frame of the vehicle terminal,the high frequency step-down circuit and the protocol drive circuit complying with various OBD-Ⅱ standards were designed.The thread scheduling algorithm was used in the slave computer and a real-time effective anti-theft warning program was designed.TCP/IP protocol was used in the mobile App to transmit information with vehicle terminals and cloud servers,and vehicles were remotely monitored in real time.Experimental results show that the system can effectively implement fault diagnosis and anti-theft warning for vehicles.
