Abstract: A set of real-time motor vehicle monitoring system is designed according to the requirement of domestic personal users and industrial users on real-time vehicle status, driving habits and fault detection. Vehicle OBD terminal acquires fault codes, location, speed and other data based on OBDII&EOBD protocol, and establishes communication with a J2EE Web server using GPRS, where the data will be analyzed in order to make diagnosis on the fault state of the vehicle, and collect statistics on vehicle status, driving habit and conditions of the driver. The final result of vehicle detection and statistical analysis will be shown on the client Web page, or iOS/Android mobile handheld device. According to the error condition of the vehicle, driver can be able to build connection with garages using this system. It will provide reference and data support for the driver’s traffic safety and facilitation, as well as the area of traffic management and insurance.

摘要： 针对国内个人用户、行业用户对实时性车辆状态、驾驶习惯和故障检修的需求，设计了一套机动车实时监测系统。基于OBDII&EOBD协议，车载OBD终端设备获取车辆故障码、地理位置、行车速度等数据信息，通过GPRS与基于J2EE架构的网站服务端建立通信。服务端对数据进行分析，从而对车辆的故障状态进行诊断，统计归纳驾驶员的驾驶习惯和行车状况，最终将车辆检测和统计分析的结果展现在网页客户端，或者iOS/Android移动手持设备上。视车辆的故障情况，驾驶员可以选择通过本系统与汽车维修厂建立联系，为驾驶员的行车安全、出行便利，以及交通管理和保险业提供参考建议和数据支持。
