What are the working principles of automatic sensing doors

Shenzhen automatic sensing doors will automatically open or close when there are moving objects or people approaching the door. Automatic sensing doors are convenient to use and have quickly become popular in many places, such as supermarkets, hotels, supermarkets, etc.

There is a sensor on the automatic sensing door. When the sensor detects that someone is entering or an object is approaching, it will send the pulse signal to the master controller, and then the master controller will judge and send it to the motor. The sensor will send a certain working current to the motor to make the motor run in the forward direction. After the motor transmits the power to the Timing belt, the Timing belt controls the lifting appliance system to open the door. After the door is opened, the controller detects and judges whether people or objects near the door are far away, and sends the door closing notice to the motor. When the motor runs in reverse, the door closes. This cycle of operation achieves the goal of automatic sensing.

The sensor can also become a microwave radar, which can detect and respond to moving objects. It is agile and can quickly detect normal human walking. When people near the door are stationary, the microwave radar will automatically close the door and no longer detect, which may trap people at the door opening. During use, it is necessary to pay attention to the speed of walking and prohibit staying at the door.

Precautions for use

1. Regularly clean the interior of the sensing door;

2. Regularly check the wear of internal components of the sensing door and replace damaged components;

3. Regularly check the speed, braking, output, and other conditions of the controller;

4. Regularly maintain the sensing door and promptly eliminate safety hazards.
