Abstract

The invention is suitable for the technical field of vehicles and provides a vehicle data acquisition terminal. The vehicle data acquisition terminal comprises a main control module, an analog quantity acquisition module, a CAN (Controller Area Network) acquisition module and a wireless communication module, wherein the analog quantity acquisition module, the CAN acquisition module and the wireless communication module are respectively connected with the main control module; the main control module is used for controlling the analog quantity acquisition module, the CAN acquisition module and the wireless communication module to work; the analog quantity acquisition module is used for acquiring analog quantity parameter information of a vehicle; the CAN acquisition module is used for acquiring first parameter information of a CAN bus of the vehicle and reading second parameter information in corresponding memories in all controllers of the vehicle through a CCP (CAN Calibration Protocol); and the wireless communication module is used for transmitting the analog quantity parameter information, the first parameter information and/or the second parameter information to a server in a wireless communication way. Accordingly, the invention further provides a vehicle information acquisition system comprising the vehicle data acquisition terminal. Therefore, according to the vehicle data acquisition terminal and the vehicle information acquisition system, the parameter information in the corresponding memories in all the controllers of the vehicle can be acquired through the CCP protocol, so that the information acquisition scope is enlarged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle-mounted data collection terminal and a vehicle information collection system. Background technique [0002] The vehicle information collection system is mainly used for vehicle remote monitoring, vehicle management, remote diagnosis and fault management, data collection and data analysis for research and development. Vehicle-mounted terminal with wireless transmission, the specific functions include vehicle positioning, driving status monitoring, historical track playback, controller data monitoring, remote fault diagnosis, data statistics and analysis, condition setting and alarm, etc. The traditional vehicle driving recorder is commonly known as the black box, which is a digital electronic recording device that can record and store the vehicle's driving speed, time, mileage and other state information about the vehicle's driving, and realize data output through the i...
