Frequency converter operation efficiency intelligent supervision system based on data analysis

The invention discloses a frequency converter operation efficiency intelligent supervision system based on data analysis, relates to the technical field of frequency converter supervision, and is used for solving the problem that an existing supervision system cannot intelligently supervise the operation efficiency of a frequency converter and cannot process the efficiency abnormity of the frequency converter in time. Comprising a data acquisition module, a database, a data analysis module, an intelligent supervision module and a signaling analysis module, efficiency information during operation of the frequency converter is acquired through the data acquisition module, the efficiency information is analyzed through the data analysis module to obtain a rate-to-change ratio and a low threshold base value, an efficiency monitoring value of the frequency converter is obtained by processing the numerical value of the rate-to-change ratio and the low threshold base value, and then the efficiency monitoring value i
