ETC entrance device and ETC exit device

Abstract

The invention discloses an ETC entrance device and an ETC exit device and belongs to the communication technical field. The ETC entrance device comprises an Ethernet communication module, an 802.11p communication module and a central processing module; and the ETC exit device comprises an Ethernet communication module, an 802.11p communication module and a central processing module. With the ETC entrance device and the ETC exit device provided by the embodiments of the invention adopted, equipment cost of a toll collection system can be decreased, and user experience can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technology, and in particular to ETC toll entry and toll exit devices. Background technique [0002] With the rapid development of my country's economy, the construction of expressways has gradually become more intelligent, and a system that can collect fees without parking has emerged as the times require. ETC (Electronic Toll Collection, electronic toll collection) system, this electronic toll collection technology, is a typical representative of the application field of intelligent transportation, and has been widely used in the highway toll collection system of our country at present. The ETC system uses electronic tags to complete the wireless data communication between the vehicle and the toll station, to automatically identify the vehicle and exchange relevant toll data, and to process the toll data through the computer network, thereby realizing a full electronic toll...

AI Technical Summary

Problems solved by technology

[0003] However, the point-to-point communication method realized by electronic tags has the following problems: it can only communicate with one vehicle at a time, that is, a set of toll system equipment must be deployed for each lane at the entrance and exit of the highway; when the wireless signal of the toll entrance covers When the range is large, the toll system will charge the rear vehicle among the two vehicles passing through the toll booth, and let the front vehicle pass; when the wireless signal coverage of the toll entrance / exit is small, the vehicle is required to only use a small low speed traffic

The existence of these problems has increased the equipment cost of the charging system, and at the same time brought a lot of unnecessary troubles to users and reduced user experience.
