Vehicle-mounted unit and system with ambiguous path identification function

Abstract

The invention belongs to the technical field of intelligent transportation, and relates to a vehicle-mounted unit and system with an ambiguous path identification function. The vehicle-mounted unit comprises a single-chip microcomputer, a wide area network module, a Beidou compatible positioning module, a DSRC (Dedicated Short Range Communication) radio frequency module and a security module, wherein the single-chip microcomputer is a core chip which is responsible for control, operation and storage; the wide area network module is used for performing authentication and data communication between the vehicle-mounted unit and a background service system; the Beidou compatible positioning module provides accurate position information and speed information of a vehicle for the single-chip microcomputer; and the DSRC radio frequency module can perform DSRC with a highway road side unit; and functions of data writing and reading are realized at the entrance and exit of a highway toll station through the security module and the DSRC radio frequency module with a DSRC antenna. The vehicle-mounted unit and the system of the invention can solve the technical problems such as static, isolated-point and lagged identification and inaccurate and incomprehensive recorded, provided and read information of the existing highway ambiguous path identification technology.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and relates to a vehicle-mounted unit and a system with an ambiguous path recognition function. Background technique [0002] Since the 1990s, my country has entered a period of rapid development of expressway construction. By the end of 2015, the total mileage of expressways in my country had reached 123,000 kilometers, ranking first in the world. With the increasing improvement of high-speed transportation network, the development model of expressway will gradually shift from large-scale infrastructure construction to intelligent management. The supporting technologies for expressway intelligent management include national networking, dynamic monitoring, and emergency response. [0003] Due to the large time span and strong regional nature of expressway planning, multiple entities are responsible for construction and operation, and a large number of ring networks are formed...
