The invention discloses an electromechanical equipment data acquisition and analysis method. A data receiving unit, a data classification unit, a database unit, a data comparison unit, a prompt unit,an authority threshold modification unit, a control unit and an instruction output unit are adopted as application software for analysis. A current acquisition sensor, a voltage acquisition sensor, afrequency acquisition sensor, a rotating speed acquisition sensor, a temperature acquisition sensor, a GPRS module and a single-chip microcomputer module which are provided with RS485 data ports are used as equipment for acquiring working current, working voltage, working frequency, rotating speed data, self temperature data and environment temperature data of electromechanical equipment. Variousdata of the electromechanical equipment can be collected in real time, the collected data are more comprehensive, managers can be prompted in time after abnormal data occur, the managers can set and modify various alarm threshold data according to the specific working state of the electromechanical equipment, and after main data thresholds of the electromechanical equipment exceed the standard, the electromechanical equipment can be controlled to stop working, and fault expansion is prevented.
