Abstract

The invention provides an on-board diagnostic data communication system. The on-board diagnostic data communication system includes an on-board diagnostic (OBD) device, a server and a mobile terminal. The OBD device is connected with an electronic control unit (ECU) of an on-board computer through an OBD port provided by a vehicle and is used for reading vehicle state data through the OBD port and sending the data to the server through a first mobile communication network. The server is used for receiving the vehicle state data sent by the OBD device, transforming the vehicle state data into preset format information and sending the preset format information to the mobile terminal through a second mobile communication network. The mobile terminal is used for receiving the preset format information sent by the server and obtaining the state of the vehicle according to the preset format information. The on-board diagnostic data communication system has the advantages that instant messaging without limitation of distance is realized, vehicle state information read by the system is more accurate and various, and more application functions are realized.

Description

[0001] Technical field [0002] The present invention relates to the technical field of automotive electronics, in particular to a vehicle-mounted diagnostic data communication system. [0003] Background technique [0004] At present, there are remote car diagnosis technologies on the market, which generally use OBD (On-Board Diagnostics, on-board diagnostic system) devices to communicate with mobile phones via Bluetooth. However, this kind of communication will be limited by the distance. In addition, the mobile phone's Bluetooth and application software must be turned on during its use, so that it cannot communicate with the device and the background server anytime and anywhere. [0005] Summary of the invention [0006] The technical problem to be solved by the present invention is to provide a vehicle-mounted diagnostic data communication system to solve the above-mentioned problems in the prior art. [0007] In order to solve the above technical problems, an embodiment of the pr...
