Speaking of Induction doors are not well understood by many people! In fact, theoretically Induction doors should be an extension of the concept of a door, and the function of a door should develop and improve according to people's needs. Automatic doors have developed very maturely. An automatic door refers to a control unit that can recognize the action of a person approaching the door (or some kind of entry authorization) as an opening signal. The induction door drive system opens the door and then automatically closes it after a person leaves, controlling the process of opening and closing. Automatic doors have been widely used in daily life and also play a protective role. They can be used in laboratories, food processing plants, fast workshops, temperature-controlled rooms, clean rooms, and various other required workspaces. Let me first explain some knowledge about automatic doors.

The basic components of induction doors are generally the same. With the above components and the opening signal, a simple automatic door system can be configured, which is a control unit that can recognize the action of a person approaching the door as an opening signal, drive the system to open the door, and then automatically close the door after the person leaves, controlling the process of opening and closing. Usually, different types of automatic doors have different working principles, as follows.

1. Working Principle of Induction Door Sensors:

When the induction door sensor detects someone entering, it sends a pulse signal to the main controller, which then notifies the motor to operate after judgment. At the same time, it monitors the motor's speed and notifies the motor to exert force at a certain time, entering a slow run. When a certain working current is obtained, the motor rotates positively to transmit power to the synchronous belt, which then transmits power to the hoisting system to open the door leaf; after the door leaf is opened, the controller will make a judgment. If the door leaf needs to be closed, it will notify the motor to move in reverse and close the door leaf.

2. Principle of Induction Door Translation:

When the sensor detects someone entering, it sends a pulse signal to the main controller, which then notifies the motor to operate after judgment. At the same time, it monitors the motor's speed and notifies the motor to work on a timer, running slowly. When a certain working current is obtained, the motor rotates positively to transmit power to the synchronous belt, which then transmits power to the hoisting system to open the door leaf; after the door leaf is opened, the controller will make a judgment. If the door leaf needs to be closed, it will notify the motor to move in reverse and close the door leaf.

3. Infrared Principle of Induction Door:

The human body temperature is generally constant, usually around 37 degrees, so it emits infrared rays of a specific wavelength of about 10UM. The automatic infrared door is based on the principle of infrared reflection. The circuit has a transmitting module and a receiving module. The transmitting module can emit infrared rays of a certain frequency and power. When encountering an obstacle, it will reflect back, be received by the receiving module, processed by the circuit or microcontroller, and execute the corresponding function.
