Barrier gates also have electric control, as Chinese patent document 201020219454.5 discloses "a kind of barrier gate opening device", including a card reader fixedly installed at the barrier gate, an IC card control processor, a barrier gate controller and a vehicle card. The card reader, the IC card control processor and the barrier gate controller are integrated into a whole. The card reader continuously sends signals to search for the car card. The car card receives the signal from the card reader and sends the car information back to the card reader. The controller transmits the received vehicle information to the IC card control processor, and the IC card control processor gives corresponding processing signals to the barrier gate controller according to the received vehicle information. This kind of gate is generally used in toll parking places. Although the IC card is used to control the gate to facilitate vehicle management and improve the anti-theft effect, the control of the gate lift is still not ideal, and the performance is unstable. The phenomenon of smashing the vehicle, and it is not suitable for use at the gate of the community.
