An etc system for preventing antenna failure

Abstract

An ETC system for preventing antenna failures includes a gravity sensing module, an antenna start discrimination module, a camera control module, a vehicle information storage module and a vehicle information matching module, wherein the gravity sensing module sends a vehicle entering signal to the camera control module and the antenna start discriminating module. The antenna start discrimination module sends a signal of successful communication between a read-write antenna and an electronic label to a lane control system or sends a signal of failed communication between the read-write antennal and the electronic label to the camera control module. The vehicle information matching module receives a vehicle information matching execution signal, matches the data transmitted by the camera control module with the vehicle information stored in the vehicle information storage module, and then sends a release signal to the lane control system after successful matching to complete a passing process. According to the invention, the problem that the ETC system can not be used due to unstable performance or failures of an antenna is solved, thereby effectively raising the normal usage efficiency of the ETC system in emergency.

Description

technical field [0001] The invention relates to the technical field of electronic non-stop toll collection systems, in particular to an ETC automatic toll collection system. Background technique [0002] ETC (Electronic Toll Collection) is a new type of charging method. Vehicles can pass through the toll booth without stopping, and complete the charging process automatically. It can significantly improve the traffic capacity of the toll booth, effectively reduce the operating cost of the toll collection, and facilitate people's daily travel. However, the performance of the antennas used in the current ETC system is not stable, especially in bad weather or unexpected situations, and cannot fully and effectively play a role. People are used to improving the performance of existing antennas by improving innovative design solutions. In order for the ETC system to be able to identify passing vehicles at any time, the performance of the antenna can be played stably. In practice, t...

However, the performance of the antennas used in the current ETC system is not stable, especially in bad weather or unexpected situations, and cannot fully and effectively play a role. People are used to improving the performance of existing antennas by improving innovative design solutions. In order for the ETC system to be able to identify passing vehicles at any time, the performance of the antenna can be played stably. In practice, things are always contrary to expectations. The failure of the antenna performance leads to the failure of the communication between the read-write antenna and the electronic tag, the ETC system cannot be used, and the vehicle goes away. stop and go
