Dsrc system wireless expandable vehicle terminal and its data processing method

Abstract

The invention provides a wirelessly expandable vehicle-mounted terminal based on a DSRC (dedicated short range communication) system and a data processing method of the vehicle-mounted terminal. The DSRC system comprises the wirelessly expandable vehicle-mounted terminal, a road side unit (RSU) and an expandable wireless terminal. The wirelessly expandable vehicle-mounted terminal comprises a basic service data processing module, a vehicle-ground wireless communication module, an expansion service terminal access management module and an in-vehicle wireless communication module. Wireless communication link can be built between the wirelessly expandable vehicle-mounted terminal and expandable wireless terminals in the vehicle by arranging the expansion service terminal access management module and the in-vehicle wireless communication module in the wirelessly expandable vehicle-mounted terminal, and therefore, not only can basic business functions of the wirelessly expandable vehicle-mounted terminal be realized, but also expanded business functions can be realized through the expandable wireless terminals, thereby adapting to the demands on the expandable functions of the vehicle-mounted terminal by an intelligent transportation system.

Description

technical field [0001] The present invention relates to a terminal device of a wireless communication system and a data processing method thereof, in particular to a terminal device based on a dedicated short-range communication DSRC system and a data processing method thereof. Background technique [0002] With the development of transportation, automobile congestion has become more and more a traffic problem. The intelligent transportation communication system represented by vehicle-to-ground communication and vehicle-to-vehicle communication has emerged. The intelligent transportation communication system is based on the dedicated short-range communication DedicatedShort-RangeCommunication system. The premise of vehicle-to-vehicle communication and vehicle-to-ground communication is that the vehicle must have a suitable vehicle-mounted communication terminal, through which the vehicle can exchange information such as vehicle status and charging amount with external roadsid...

AI Technical Summary

Problems solved by technology

[0004] In order to reduce cost pressure and be suitable for widespread application, there are still some low-cost, single-function vehicle-mounted terminals in the existing technology, such as electronic tags for non-stop charging

However, this low-cost vehicle-mounted terminal cannot realize more intelligent transportation expansion functions, and becomes a simple charging label, which cannot introduce new services

For example, if it is applied in the ElectronicTollCollection system for non-stop charging, the vehicle-mounted terminal only completes the function of the stored-value card, and when passing through the roadside equipment, the fee deduction process is completed through the vehicle-mounted terminal. The balance of fees in the system cannot be directly reflected to the car owner, making the car owner question the convenience of the car terminal

In addition, the vehicle-mounted terminal has a single function and does not provide an effective development approach for possible expanded functions, so that the vehicle-mounted terminal cannot meet the development needs of the intelligent transportation communication system

[0005] Therefore, the vehicle-mounted terminal in the prior art is either a complex vehicle-mounted computer system, which cannot be deployed quickly and cheaply for a specific application, such as electronic toll collection applications; The vehicle-mounted terminal in the charging ETC cannot evolve to a better application in the future, resulting in weak application and lack of follow-up development potential
