This paper mainly introduces an infrared optical communication system basedon stable and handstand pendulum. This system adopts the method of loading theinfrared light emitting end on an handstand pendulum to realize the stabilityand controllability of the infrared light transmission light path. In thissystem, 940nm infrared light is mainly used for audio signal transmission, andan handstand pendulum based on PID is used to control the angle and stabilityof infrared light emission. Experimental results show that the system caneffectively ensure the stability of the transmission optical path and issuitable for accurate and stable signal transmission in bumpy environments.
