The invention discloses an automatic cleaning and maintenance control method and system for water quality monitoring equipment and a medium, and belongs to the field of water quality monitoring. The method comprises the steps that pure water generated by a built-in pure water production assembly of equipment serves as a measurement anchor point, and whether sensors are normal or not is judged on the basis of comparison results of detection numerical values of the sensors in a pure water environment and a preset pure water threshold value; monitoring operation state parameters of the pure water production assembly, and dynamically adjusting and updating the pure water threshold value corresponding to each sensor; when the value of the sensor deviates from the threshold value, first-stage pure water flushing is executed; if not, second-stage maintenance is started according to the sensor type, the optical sensor performs optical path self-cleaning or backwashing, and the electrochemical sensor performs electrode cleaning; and detecting again after maintenance, and locking the sensor and generating a fault alarm if the sensor is still not recovered. Through dynamic threshold configuration, progressive maintenance and sensor adaptive cleaning, the problems of reference drift and deep pollution are solved, the data credibility is improved, and the operation and maintenance cost is reduced.

Embodiments of the present application provide a kind of fault detection method, device and equipment of mutual inductor and mutual inductor, it is related to power system technical field.The method comprises: obtaining the multiple sensor data that multiple sensors deployed in mutual inductor are collected in real time;According to the first feature information corresponding to multiple sensor data, determine the fault score of mutual inductor;Obtain the historical sensor data of mutual inductor, and according to multiple sensor data, historical sensor data and the equipment related information of mutual inductor, determine the dynamic fault threshold corresponding to mutual inductor;If according to fault score and dynamic fault threshold, it is determined that mutual inductor exists fault, then according to the second feature information corresponding to multiple sensor data, determine the fault type of mutual inductor.The method of the present application can comprehensively, accurately and efficiently realize the fault detection of mutual inductor, to help guarantee the stable operation of power system.
