【Abstract】 This paper studies the circuit troubleshooting and light radiation pollution control of photoelectric physiotherapy instrument.Based on the characteristics and application scope of various photoelectric physiotherapy instrument models, as well as the working principle of its power supply part and circuit part, and according to the composition of the oscillation circuit and the oscillation frequency of the integrated block, the frequency signal of the relevant pin is solved.Under the static detection, the multimeter is used to measure the input and output resistance of each element to complete the circuit troubleshooting; Through the formation factors of light radiation pollution, the control strategies such as changing the irradiation form and structure and reasonable inclination angle are put forward, so as to control the light radiation pollution.The simulation results show that this method not only accurately eliminates the circuit fault of the physiotherapy instrument, but also controls the light radiation pollution to a great extent, which is practical and feasible.更多还原
