Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle track perception, and more specifically to a vehicle track perception device based on ETC technology. Background Art
[0002] ETC, or Electronic Toll Collection, is a highway toll collection method that does not involve manual cash transactions. The ETC system uses wireless communication technology, on-board equipment, and roadside equipment to automatically collect tolls without the need for vehicles to stop or pay cash. Vehicles need to be equipped with ETC on-board equipment, which is usually installed on the inside of the front windshield of the vehicle. Roadside equipment includes antennas, cameras, etc., which are used to read information from the ETC equipment on the vehicle and perform identification and billing. These devices are usually installed at the entrance and exit of toll booths. When a vehicle enters the ETC toll area, the ETC device communicates with the roadside equipment through wireless signals to transmit the vehicle's identification information and related data. The roadside equipment sends the identification and billing information to the relevant backend system to calculate the amount to be collected. Car owners can automatically pay the required fees through a pre-set account or by binding with a bank card. The ETC system is fast, convenient, and efficient, reducing traffic jams and queuing time and improving the smoothness of road traffic. The ETC system also helps save fuel consumption and reduce exhaust emissions because vehicles do not need to stop and wait to pay. ETC has been widely used in many countries and regions, and has gradually become one of the main highway toll collection methods. In short, the ETC system realizes automated highway toll collection by utilizing electronic technology and communication equipment, thus improving traffic efficiency and convenience.
