Digital wireless electronic road and parking ground charging system

Abstract

The embodiment of the invention provides a digital radio electronic system for toll collection of roads and parking lots. The system comprises a first radio transmission device which is arranged at a toll collection monitoring point and is used for transmitting and looking up a message required by an electronic license plate; a first radio receiving device which is arranged in an vehicle entering or exiting a toll station and is used for receiving and decoding a first radio signal; a second radio transmission device which is arranged the vehicle entering or exiting a toll station and is used for transmitting a second radio code signal including information of the electronic license plate; a second radio receiving device which is arranged at the toll collection monitoring point and is used for receiving and decoding a second radio signal; a monitoring point processor which is used for controlling, coding and decoding signals from the monitoring point; a vehicular processor which is used for controlling, coding and decoding signals of vehicles entering or exiting the toll station; an electronic license plate unit which is used for storing information of an electronic license plate identification code; and a toll charging unit which charges according to vehicle classes and the entering and exiting time thereof. The system has the advantages of being reliable, environmental protection, 24-hour service, being easy to be realized, convenience in integration with an ITS system and the like.

Description

technical field [0001] The invention relates to a road and parking lot charging system, in particular to a digital wireless electronic road and parking lot charging system. Background technique [0002] Electronic Toll Collection (ETC for short) is a system composed of equipment and software using wireless technology, electronic technology, computer technology, communication network technology, sensor technology, image recognition technology, etc. A charging method that can automatically collect road tolls. From the current technical means, it can be divided into three types: DSRC (Dedicated Short Range Communication, short-range wireless communication), ANPR (Automatic Number Plate Recognition, license plate recognition), and VPS (Vehicle Positioning System, vehicle positioning system). [0003] DSRC electronic toll collection is a relatively mature toll collection technology in the world in recent years. It is a charging technology that uses roadside equipment to connect...

AI Technical Summary

Problems solved by technology

[0007] (1) ANPR technology is immature, and the accuracy of license plate recognition is not high. At the same time, it is easily affected by weather conditions and cannot achieve stable work around the clock. This is the biggest obstacle restricting the development and application of technology.

[0008] (2) Although DSRC technology is mature, it requires high cost to build and maintain roadside equipment, and also affects the city's landscape to a certain extent, so it is usually used on the main road of traffic, and its microwave radiation problem and Electromagnetic interference is also a questionable issue

[0009] (3) Although VPS technology has high flexibility, its vehicle-mounted device has a high investment, and the update of vehicle-mounted electronic map is complicated. In urban roads, GPS positioning signals are easily blocked by buildings, and if the system design is not reasonable , will involve issues such as user privacy
