[0002] Electric doors are a type of door that is opened and closed by a motor or electric device. Electric doors are widely used in commercial buildings, residential buildings, hospitals, hotels and other places. In order to ensure the safety and effective operation of electric doors, they are usually equipped with some sensing and control devices, among which infrared devices are one of the commonly used technologies.

[0003] Most of the infrared safety devices installed on both sides of the door on the market are four-wire infrared devices, and need to be equipped with corresponding motors to connect to the four wiring ports of the infrared safety device. The signal is fed back through the signal line of the four-wire infrared safety device to achieve control of the motor. However, the wiring of the four-wire infrared device is relatively complicated, and it is easy to make the line difficult to repair later during wiring. Therefore, an infrared safety device with simple wiring, convenient maintenance and can be applied to motor control is needed. Utility Model Content

[0006] Furthermore, the rectifier module 1 and the rectifier module 2 are full-wave rectifier circuits, and there is no need to distinguish between positive and negative poles when connecting to the power module.

At the same time, by setting the connection circuit between the transistor 2 and the field effect transistor, the resistor 5 instantly divides a part of the voltage of the transistor 2 after it is turned on.

[0009] Furthermore, the receiving and decoding module includes an infrared receiving tube and a single-chip microcomputer module 2 connected to the infrared receiving tube.
