Abstract

The invention discloses an OBD communication system based on 4G network communication and Beidou communication. The OBD communication system comprises OBD equipment, a communication module and a platform server. The OBD equipment is connected with the platform server through the communication module; the communication module is connected with the platform server; the communication module comprisesa Beidou communication unit, a 4G communication unit and a switching module; the switching module is connected with the Beidou communication unit and the 4G communication unit and used for switchingBeidou communication and 4G communication, and the Beidou communication unit is used as a communication mode of the OBD communication system when the automobile runs in a remote area without 4G network coverage; and the 4G communication unit is used as a communication mode of the OBD communication system when the automobile runs in an area covered by the 4G network. According to the OBD communication system based on 4G network communication and Beidou communication provided by the invention, the limitation of the application range of conventional vehicle-mounted OBD equipment can be effectively solved, and the operation cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobile communication services, in particular to an OBD communication system and method based on 4G network communication and Beidou communication. Background technique [0002] OBD equipment on the market collects car information data through the car OBD interface, and obtains car diagnosis results after calculation and processing. [0003] In the prior art, the way of data processing is: based on the communication methods of WiFi, GPRS and 4G, after reading the information through the OBD interface, the car information data is uploaded to the platform server, and big data analysis such as car failure and driving behavior is carried out , After the processing is completed, the result is pushed to the customer's mobile phone APP, and the car owner can easily and quickly know the car status. [0004] Using existing communication methods to obtain vehicle information has the following problems: [0005...
