The signal after two-stage amplification by the preamplifier and the limiting amplifier is filtered by the band-pass filter to remove the noise interference of other frequency components, and then the envelope pulse is detected by the detector, and after shaping, it is converted into a standard coded pulse and output to the control device.

If the infrared receiving device fails to receive the pulse signal, the control device controls the power switch of the production equipment to be disconnected, and at the same time issues an alarm reminder to prevent staff from accidentally entering the dangerous area and causing personal injury.
