Vehicle-mounted mobile terminal based on dsrc and its communication method

Abstract

The invention provides a DSRC-based vehicle-mounted mobile terminal and a communication method thereof. The vehicle-mounted mobile terminal comprises a positioning module, a data acquisition module, a DSRC communication module and an information processing module, wherein the positioning module receives navigation positioning signals from a navigation system continuously to acquire the position information and the driving direction information of the current vehicle; the data acquisition module acquires the operation state information of the current vehicle via a sensor; the DSRC communication module receives information sent by external equipment; and the information processing module is respectively connected with the positioning module, the data acquisition module and the DSRC communication module for processing the position information and the driving direction information of the current vehicle and the information sent by the external equipment and executing operation corresponding to a processing result. Real-time large data amount transmission of the mobile vehicle can be realized, the data downloading rate of the vehicle is improved, and batch data downloading can be realized; and information interaction between vehicles is enhanced, a vehicle driver can know better about the road condition information, and the traffic accident happening rate can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and relates to a vehicle communication device, in particular to a DSRC-based vehicle-mounted mobile terminal and a communication method thereof. Background technique [0002] With the development of the economy and the advancement of science and technology, the intelligentization of the future urban traffic environment is also developing rapidly. A large number of new vehicle wireless communication applications generated by urban traffic networks, such as: real-time traffic broadcast, video on demand, map download, etc., are used to meet the needs of intelligent vehicle information. During the driving process, large-scale data information exchange is required between the vehicle and the base station. [0003] The current intelligent transportation system is mainly based on the widely used 2G / 3G network. Many in-vehicle service companies mainly download service information fro...
