Real-time data transmission method and system based on Internet of Vehicles

Abstract

The invention discloses a real-time data transmission method and system based on the Internet of Vehicles, and relates to the field of information transmission. The method comprises the following steps: S001, a T-box control unit sends a request command to an engine ECU through a CAN communication bus; S002, the engine ECU sends state feedback to the T-box after receiving the message; S003, the T-box performs processing on the collected data in a preprocessing mode and storing the same; S004, the data are uploaded to an Internet of Vehicles TSP platform through incremental detection and data compression; and S005, a mobile terminal acquires the information of the Internet of Vehicles TSP platform through the Ethernet and displays the information. According to the real-time data transmission method and system, vehicle data communication connection and communication are performed through the CAN communication bus, the T-box collects vehicle control information and positioning information, key and abnormal information are selected by a preprocessing module and are uploaded to the Internet of Vehicles TSP platform, the Internet of Vehicles provides an access platform for the mobile terminal, thus improving the utilization of resources, reducing the running load of the server, and increasing the efficiency of data transmission.

Description

technical field [0001] The invention belongs to the field of information transmission, and in particular relates to a real-time data transmission method and system based on the Internet of Vehicles. Background technique [0002] Nowadays, with the improvement of people's living standards, more and more vehicles are pouring into individuals, families, and enterprises; the amount of data that needs to be collected by the Internet of Vehicles is increasing; with the Ministry of Transport in 2012, all commercial vehicles must be equipped with car driving records All commercial vehicle manufacturers are required to install driving recorders on vehicles to report vehicle positioning, turn signals, brake signals, etc. in real time. Considering the cost and the functional limitations of ordinary driving recorders, we use the CAN bus communication technology and the 1939CAN communication protocol to realize the data interaction between the vehicle driving recorder and the commercial ...
