Remote vehicular terminal based on safety and diagnosis

Abstract

The invention relates to a remote vehicular terminal based on safety and diagnosis. The remote vehicular terminal comprises a single-chip microcomputer, a communication adapter, a wireless communication module, a GPS (global positioning system) module, a storage module, a keyboard module, a vehicle state information input module, a voice video output module, an LED indicating lamp, and a power supply module. The communication adapter, the wireless communication module, the GPS (global positioning system) module, the storage module, the keyboard module, the vehicle state information input module, the voice video output module, the LED indicating lamp, and the power supply module are respectively connected with the single-chip microcomputer. The vehicle state information input module collects vehicle state information and transmits the same to the single-chip microcomputer. The GPS module collects the positioning information of vehicles and transmits the same to the single-chip microcomputer. The single-chip microcomputer stores the information locally and compares each information with the set threshold to judge whether the information is normal or not, and if not, the single-chip microcomputer gives out an alarm locally and transmits the alarm information to a user through the wireless communication module. Compared with the prior art, the remote vehicular terminal has the advantages of wide application range, multiple compatible platforms, great real-time performance, large recording data amount and high integrated level.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal, in particular to a remote vehicle-mounted terminal based on safety and diagnosis. Background technique [0002] At present, there are various types of vehicle-mounted terminals on the market, with relatively few interfaces and relatively single functions, such as only GPS data upload function. Moreover, the accuracy of GPS data is not high. [0003] Related literature also discloses a vehicle-mounted terminal with a single CAN communication interface, but the data communication protocol it supports is limited to the J1939 protocol, which cannot effectively obtain vehicle control parameters and control the vehicle in real time. Contents of the invention [0004] The purpose of the present invention is to provide a wide range of use, many compatible platforms, good real-time performance, large amount of recorded data, high integration, integrated driving recorder, anti-dismantlement, easy upgrade, i...
