As we all know, automatic door sensors are widely used in public places such as shopping malls, hotels, banks, office buildings, airports, etc. The most common sensor is the ATF830 automatic door sensor, which automatically opens the door when people approach the door and automatically closes the door when people walk, making it very convenient. So, what is the working principle of automatic doors?
Working Principle of ATF830 Automatic Door Sensor
The basic composition of the automatic door machine is basically the same, coupled with the door opening signal, which can be configured as a simple automatic door system.
The system configuration of automatic doors refers to peripheral auxiliary control devices that are equipped according to usage requirements and connected to automatic door controllers, such as door opening signal sources, access control systems, security devices, centralized control, etc.
The opening signal of an automatic door is a contact signal, and microwave radar and infrared sensors are two commonly used signal sources:
The ATF830 microwave radar is responsive to the displacement of objects, and therefore has a fast response speed. It is suitable for places where people with normal walking speed pass through. Its characteristic is that once people near the door do not want to go out and remain stationary, the radar will no longer respond, and the automatic door will close, providing a certain protection for the door operator;
The infrared sensor reacts to the presence of an object. Regardless of whether a person is moving or not, as long as it is within the scanning range of the sensor, it will react and send out a contact signal. The disadvantage is that the infrared sensor has a slower reaction speed and is suitable for places where people with slow movements enter and exit.
