The invention relates to the field of automobile supervision, in particular to an OBD (On-Board Diagnostic) vehicle-mounted pledge supervision Internet of Things terminal. The OBD analyzer sends and receives a data frame returned by automatic analysis of an OBDII standard protocol message from an OBD interface, extracts vehicle information and sends the vehicle information to a bus; the power supply supplies power to other modules of the pledge supervision controller; the terminal management module processes the data flow returned by the OBD interface; the communication module is used for receiving the data stream of the terminal management module, generating a data frame and sending the data frame according to a specified address; and the security protection module is used for encrypting the information of the communication module. According to the invention, the OBD standard interface is utilized to analyze the basic information of the vehicle, the application based on the vehicle information is developed through the embedded system, the information flow of various types of vehicles is matched through an efficient algorithm, and the information transmission is completed with lower power and higher efficiency through the communication module used as required; and information is provided for a user through a specific interface of the terminal management system.

    本发明涉及汽车监管领域,具体涉及OBD车载质押监管物联网终端,OBD接口输出车辆状态数据;OBD解析器从OBD接口发送和接收OBDII标准的协议报文自动解析返回的数据帧,并提取车辆信息向总线发送;电源对质押监管控制器的其他模块进行供电;终端管理模块处理OBD接口返回的数据流;通信模块,用于接收终端管理模块的数据流,并生成数据帧,按指定地址发送;安全防护模块,用于对通信模块的信息进行加密处理。本发明利用OBD标准接口解析车辆基础信息,并通过嵌入式系统开发基于车辆信息的应用,通过高效的算法,匹配各型车辆的信息流,通过按需使用的通信模块,以较低功率和较高效率完成信息的传递,并通过终端管理系统的特定接口向使用方提供信息。
