Wirelessly expandable vehicle-mounted terminal based on DSRC (dedicated short range communication) system and data processing method thereof

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 the transportation industry, automobile congestion has become more and more a traffic problem, and 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 dedicated short-range communication Dedicated Short-Range Communication 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 w...

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 Electronic Toll Collection 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 vehicle-mounted terminal completes the fee deduction process. The balance of fees in the vehicle-mounted terminal cannot be directly reflected to the car owner, making the owner question the convenience of the vehicle-mounted 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
