Intelligent vehicle-mounted terminal based on Beidou positioning

Abstract

The invention relates to an intelligent vehicle-mounted terminal based on Beidou positioning. The terminal comprises an FM radio receiver, a display module and a power module, and further comprises acontroller, a storage, a CAN module, a communication module, an inertia navigation module and a Beidou navigation positioning module; the controller is respectively connected with the storage unit, the CAN module, the communication module, the positioning module, the power module, the display module and the FM radio receiver; the CAN module is used for acquiring ECU information connected on a CANbus through the CAN bus and analyzing the ECU information; the communication module is used for information exchange between the intelligent terminal and a cloud platform or other terminals; the storage is used for storing one or multiple of the ECU information, the information sent by the cloud platform or the terminal, the vehicle location information, and the map information; and the running switching of the inertia navigation module and the Beidou navigation positioning module is realized through the controller. The vehicle-mounted terminal can report the location information of the vehicle located by the terminal to the platform at fixed time under a signal-free state.

Description

technical field [0001] The invention relates to the field of vehicle-mounted terminals, in particular to an intelligent vehicle-mounted terminal based on Beidou positioning. Background technique [0002] The Internet of Vehicles technology requires the car to have a comprehensive judgment on the driving environment and to perceive potential risk factors in advance. The smart terminal should fully monitor the running status of the car itself, upload the information of the car's speed, engine speed, and lane, and provide real data for the platform through cloud processing to ensure that the information processing center can make judgments based on accurate information and Send the corresponding service information. The existing vehicle-mounted terminal cannot provide the function of remotely controlling the vehicle, and fails to collect, analyze and control the information of the vehicle through the CAN bus. The function is single, it is not convenient for users to use, and ...

AI Technical Summary

Problems solved by technology

The existing vehicle-mounted terminal cannot provide the function of remote control of the vehicle, and fails to collect, analyze and control the information of the vehicle through the CAN bus

The function is single, inconvenient for users to use, and it is difficult to meet the expansion needs of the Internet of Vehicles

On the other hand, it is difficult for existing vehicle-mounted terminals to send vehicle information such as positioning to the cloud platform in a timely manner in places where the satellite signal is weak or the network signal is poor, and it may even lose contact with the cloud platform, posing a great security risk
