Intelligent monitoring system and intelligent monitoring method for frequency converter

The invention relates to an intelligent monitoring system and an intelligent monitoring method for a frequency converter. The intelligent monitoring method comprises the following steps: acquiring working parameters of each functional unit; acquiring warning parameters of each functional unit; comparing the working parameters and the warning parameters of the same functional unit, if the working parameters exceed the warning parameters, sending out warning signals, wherein the warning signals comprise labels corresponding to the functional units with the working parameters exceeding the warning parameters. The electric energy has different states in different functional units in the frequency converter, corresponding warning parameters are respectively set for each functional unit, and actual working parameters of each functional unit are acquired and compared, so that whether the working state of each functional unit is normal or not can be intuitively known, and the frequency converter can be monitored more
