Automatic car stopper device capable of preventing accidental hitting with warning function

Abstract

The invention discloses an automatic car stop device for preventing accidental smashing with a warning function, which comprises a barrier bar and a control box. The barrier bar is connected to one end of the control box, and also includes an ultrasonic box arranged opposite to the control box. , the ultrasonic box is set on the free end side of the barrier bar; the ultrasonic box is provided with an ultrasonic transmitter on the inner side facing the control box, and the control box is equipped with a signal converter, a controller, and a driver for the barricade bar. There is an ultrasonic receiver facing the ultrasonic transmitter outside the box; the ultrasonic receiver is electrically connected to the signal converter, and the signal converter is electrically connected to the controller; the controller is electrically connected to the gate lever driver, and the gate lever driver drives the connection channel A brake lever; a warning light is also arranged on the top surface of the control box, and the warning light is electrically connected with the controller. The automatic car stopper device can prevent a barrier bar from accidentally hitting a human body and a vehicle.

Description

technical field [0001] The invention relates to the field of road equipment, and specifically designs an automatic car stop device for preventing accidental smashing with a warning function. Background technique [0002] The automatic car stop is generally composed of hardware facilities such as a barrier control system, a computer, a ground sense coil, a barrier pole, a speed bump, and an entry and exit sign. The ground induction coil is a closed-loop wire buried shallowly in the ground. It uses the principle of electromagnetic induction to identify metal substances above the ground (such as the metal chassis of a car), thereby giving the gate control system a signal of vehicle entry and exit. The ground sense coil is generally set in three places in front of, directly below and behind the barrier bar, so as to judge the complete information of the vehicle passing through the barrier bar. The barricade automatically drops after the vehicle leaves the last ground loop. Man...

AI Technical Summary

Problems solved by technology

Many vehicles pass continuously. Once the chassis of individual vehicles is too high or the non-metallic chassis armor is installed, the time signal of the ground sense coil is not obvious. The phenomenon that the gate pole hits the vehicle by mistake
