Abstract

The invention proposes a transaction antenna with a function of vehicle detection, and a transaction method, and aims at ironing out the defects that a lane is liable to be damaged by a heavy-duty vehicle and road repair in the conventional ground induction coil and infrared grating detection technology. The transaction antenna also has the functions of vehicle detection and queue judgment processing besides the original ETC electronic tag positioning function, and comprises a first microwave emission plate, a second microwave emission plate, a vehicle detection function module, a microwave positioning module, a support, and an RSU main control board. The vehicle detection module is integrated in the transaction antenna, thereby facilitating the overall coordination control and transaction charging, shortening the construction time of an ETC lane, improving the reliability and intelligentization of an ETC system and the passing capability, alleviating the traffic jam, and enlarging the application range of the ETC system.

Description

technical field [0001] The invention relates to a new type of transaction antenna for vehicle detection and a transaction method thereof, in particular to a transaction antenna and a transaction method for expressway non-stop charging that can perform vehicle detection and queue judgment processing. Background technique [0002] After more than ten years of application and innovation in the domestic expressway ETC system, the technology has been perfected day by day. New products such as phased array antennas have been launched one after another. At the end of 2015, the national ETC network was realized. At present, the number of ETC users has exceeded 50 million. The normal operation of the ETC lane system is inseparable from vehicle identification and queuing logic judgment. At present, the technologies adopted on a large scale include ground sensing coil detection and infrared grating detection method. The disadvantages of these two detection methods are low stability and ...
