Vehicle access pneumatic barrier gate system

Abstract

The invention discloses a vehicle access pneumatic barrier gate system. The system comprises a barrier gate driving mechanism, a license plate recognition camera mechanism, a vehicle detector and a single-chip microcomputer control mechanism. The barrier gate driving mechanism comprises a rack, a gate rod, a driving air cylinder, an electromagnetic air valve and a manual air valve. One end of thegate rod is hinged to the rack, the driving air cylinder is vertically arranged, the bottom of the driving air cylinder is a fixed end, the top of the driving air cylinder is a piston end, the fixed end is hinged to the rack, and the piston end is hinged to a gate rod and used for driving the gate rod to turn over. The license plate recognition camera mechanism and the vehicle detector are arranged on the two sides of the brake rod respectively and connected with the single-chip microcomputer control mechanism. The manual air valve and the electromagnetic air valve are connected with the driving air cylinder, and the electromagnetic air valve is connected with the single-chip microcomputer control mechanism. Operation of the brake rod is not affected by power failure, the requirement for the strength of the brake rod is low, the brake rod is not prone to shaking, and a noise in a rising and falling process is low.

Description

technical field [0001] The invention relates to the technical field of barrier gate equipment, in particular to a vehicle access pneumatic barrier system. Background technique [0002] Barrier gates, also known as car stoppers, are passageway entrance and exit management equipment used to restrict motor vehicles on the road, and are now widely used in road tolls, residential areas, etc. [0003] At present, the lift of the barrier gate is generally driven by a motor. When this kind of barrier is installed in a place with a large crossing span, on the one hand, it requires a very long brake rod, which requires high strength of the brake rod; The rotation torque is required to be large, and the brake lever is easy to shake, especially when running in windy weather, the noise caused by the shaking of the brake lever is large. [0004] In addition, a power outage will cause the barrier gate to fail. When the barrier gate is driven up and down manually, the overturning of the b...

Problems solved by technology

When this kind of barrier gate is installed in a place with a large crossing span, on the one hand, it requires a very long brake rod, which requires high strength of the brake rod; The rotating torque is required to be large, and the brake lever is easy to shake, especially when running in windy weather, the noise caused by the shaking of the brake lever is large

[0004] In addition, a power outage will cause the barrier gate to fail. When the barrier gate is driven up and down manually, the overturning of the barrier gate will drive the reducer to operate together, increasing the operating load of the reducer, and it is also prone to failure or damage. The operation can only be carried out after opening the chassis of the gate movement, which is very inconvenient to operate
