The basic principle and application of tripod turnstile gate

Generally, we use an access controller to control the switch signal of the tripod turnstile gate. The NO and GND in the access control system are connected to the line of the 3 arm turnstile gate switch, and the NO signal line of the access control system achieves the closing effect of the switch, thereby playing the card swiping the effect of the access control function passed. When someone enters, swipe the ID recognizer at the entrance. At this time, the access control system recognizes whether the card is a legal card and whether it can be authorized to pass according to the information of the ID card. After the CPU of the access control system compares successfully, the RFID tripod turnstile gate will receive it. Upon receiving a control signal, turn on the switch of the gate to allow the person to enter.

2. Application 
One of the most important reasons for choosing a three-roller gate card swipe access control system is that the tripod baffle gate is relatively durable and has strong anti-collision ability. Due to the concentrated flow of people at the entrance of the examination room, candidates are often crowded when they swipe their ID cards to pass through the three-roll gate. When the gate does not pass the signal, they will walk to the gate and ask to pass. This will cause the flow of people to collide with the turnstile multiple times. If a swing gate or a wing gate is used, it is prone to closing failures, and the three-roller gate is equipped with a buffer device to prevent collisions, which can protect the turnstile from damage. , Thereby avoiding this failure.

In addition, due to the working principle of the three-roller gate, it can greatly increase the passing speed of the flow of people and avoid the stagnation of a large number of people. Therefore, the three-roller gate access control system is very suitable for use in the entrance and exit of public places.
