Abstract

The invention belongs to the technical field of Internet of vehicles, and particularly relates to a phased wireless data transmission system. The phased wireless data transmission system mainly comprises three basic functional modules of a core processor, a non-volatile data storage module and a wireless data transmission module, as well as auxiliary modules of a power supply management module, a wireless data switch, an indicating lamp and a loudspeaker. By adopting the phased wireless data transmission system, phased wireless data transmission of external mobile equipment can be realized through user control or the change of real-time vehicle data obtained from a vehicle electronic system, thereby bringing greatest convenience to acquisition of vehicle data by the user, meanwhile reducing the influence on normal use of mobile Internet or Bluetooth communication of the user, ensuring complete transmission of driving data from a vehicle side to a mobile terminal equipment side, and greatly improving user experience.

Description

technical field [0001] The invention relates to a data transmission system, in particular to a staged wireless data transmission system, which belongs to the technical field of the Internet of Vehicles. Background technique [0002] The function of On Board Diagnostic (OBD) is to detect the operating parameters of each system of the car and read the running data of the vehicle. Initially, its purpose is mainly to detect the exhaust emission of the car to meet the requirements of environmental protection. With the development of technology, the current application of OBD has far exceeded the simple environmental protection detection and expanded to the detection of various sensors in the whole vehicle and the access to the on-board computer. After the system is started, it will enter the engine, gearbox and other systems to read fault codes and other sensor data through the on-board computer, and finally access data with external devices through the standard OBD interface con...
