The ETC system is also called a non-stop payment system, microwave card reading devices are installed at a high-speed inlet and an outlet, an electronic tag card is installed on a front windshield of a vehicle, and the electronic tag card is bound with a bank card of a vehicle owner. When a vehicle drives into the ground induction coils embedded in the high-speed entrance lane and the exit lane, the microwave card reader is triggered to read the information of the electronic tag card in the vehicle, so that the vehicle information and the payment information are read, the built-in program automatically completes the payment process, and the barrier gate is opened, so that the vehicle can drive into and out of the highway without stopping. Although the ETC electronic toll collection system improves the vehicle passing efficiency to a certain extent, after the microwave card reader reads the information of the electronic tag card in the vehicle and sends the information to the barrier, the barrier with the fastest reaction can raise the barrier to enable the vehicle to pass, the distance between the position where the microwave card reader is installed and the position where the barrier is installed is not too far, the vehicle must slow down and slowly move when passing between the microwave card reader and the barrier, the identification and processing time of the existing ETC system can meet the condition that the vehicle passes through quickly, but the reaction speed of the existing barrier seriously influences the passing speed of the vehicle.

The barrier utilizes the first driving device 3 to drive the brake bar 8 to swing up and down, and simultaneously utilizes the second driving device 6 to drive the brake bar 8 to swing along the advancing direction of the vehicle, so that the brake bar 8 swings in an arc shape towards the front upper part, when the vehicle approaches, because the brake bar 8 moves forwards upwards, the time for the brake bar 8 to swing to the position where the vehicle can pass only needs about half of that of a common barrier, thus the vehicle can normally pass through without reducing speed when passing through, and the reaction speed of the barrier can not influence the passing speed of the vehicle no matter the barrier is applied to an expressway or other parking passages.
