In order to improve the signal transmission efficiency of electrical equipment and improve the timeliness and accuracy of electrical equipment condition detection,the state detection method of electrical equipment based on semiconductor laser interference technology is studied. Using semiconductor laser interference technology combined with optical fibre pressure sensing technology,the pressure parameters of the equipment in operation are obtained,and the corresponding knowledge rules are used to judge the operation status of the equipment. The status detection of the electrical equipment is realised. The fault causes of the electrical equipment are analysed and judged according to the signal data,and the corresponding maintenance measures are proposed. Experiments show that: this method can accurately measure the running state and fault state of electrical equipment by detecting the vibration frequency characteristics of electrical equipment,and has good detection effect of fault state of electrical equipment;and after the application of this method,the delay time of signal transmission from electrical equipment to the upper computer in the control room is the shortest,the average transmission rate of the signal is high,and the average bit error rate of signal transmission is low high efficiency and accurate detection of standby state.
