The invention provides a GIS circuit breaker operation state monitoring method and system based on sound and image features, and belongs to the technical field of circuit breakers. Comprising the following steps: acquiring image time sequence data in an operation state of the GIS circuit breaker in real time and identifying an opening and closing state of the GIS circuit breaker, when the GIS circuit breaker is identified to be in a closing state, acquiring sound signal time sequence data in the operation state of the GIS circuit breaker in real time through a voiceprint sensor, and constructing a GIS circuit breaker sound feature identification model, and analyzing and identifying the extracted sound signal characteristics in the operation state of the GIS circuit breaker to obtain the operation state of the GIS circuit breaker, thereby realizing real-time monitoring of the operation state of the GIS circuit breaker and efficient, accurate and rapid identification of the abnormal state, timely finding the ab
