Integrated frequency converter operation state monitoring system and monitoring method

The invention relates to the technical field of frequency converter monitoring, and discloses an integrated frequency converter operation state monitoring system and method, and the method comprises the steps: collecting a current or voltage signal of each preset local target circuit; generating an operation state evaluation coefficient according to the current or voltage signal; performing primary judgment on the operation state evaluation coefficient to obtain a frequency converter with a sudden operation fault; determining corresponding sudden fault information based on a corresponding relationship between a preset fluctuation measured data value and the sudden fault information; extracting actually-measured temperature data and actually-measured vibration data of each preset local target circuit in a preset time span, and generating an actually-measured temperature trend chart and an actually-measured vibration trend chart based on the actually-measured temperature data and the actually-measured vibration
