Abstract

The invention discloses an automobile long-distance information system. The system comprises a vehicular terminal, a wireless network and a monitoring center. The vehicular terminal is connected with the monitoring center through the wireless network, and the vehicular terminal is composed of a power module, a display interface, a 4G (fourth-generation) module, a main control chip, an original vehicle communication bus, and external sensor universal interfaces. The wireless network comprises a base station. The monitoring center comprises a server, an identity authentication module, and a client-side. A vehicle power supply is connected with the main control chip through the power module. The main control chip is in one-way communication with the display interface through a communication interface, is in both-way communication with the 4G module through the communication interface, is in one-way communication with the original vehicle communication bus through a CAN (controller area network) interface, and is in both-way communication with the external sensor universal interfaces through external interfaces. The vehicle terminal is in wireless data connection with the base station through the 4G module. The base station is in wireless data connection with the server.

Description

technical field [0001] The invention relates to the field of telematics systems for automobiles, in particular to a telematics system for automobiles based on 4G wireless communication protocols. Background technique [0002] The vehicle telematics system is a system that utilizes the telematics transmission technology to enable the vehicle information server to exchange information with the vehicle. It can be used for road test calibration of vehicles, data collection and collection of driving information of real vehicle users, which greatly improves the convenience of data interaction during the operation of real vehicles. At present, there are different patents and products focusing on the monitoring, calibration, diagnosis and other functions of the telematics system. Such as figure 1 Shown is a schematic diagram of the existing automotive telematics system. The data collection of the current automotive telematics system is only based on the original vehicle communicat...
