The invention provides a tower crane integrated frequency converter control system. The system comprises a central controller, and the central controller comprises a control instruction module, a dataacquisition module and a switching value unified management module. The control instruction module is in communication connection with a lifting motor frequency converter, a variable-amplitude motorfrequency converter and a rotary motor frequency converter and is used for sending a control instruction. The data acquisition module is connected with the lifting motor, the variable-amplitude motorand the rotary motor and is used for acquiring real-time data of current, rotating speed and operating frequency of the lifting motor, the variable-amplitude motor and the rotary motor. The switchingvalue unified management module is connected with the data acquisition module and is used for receiving the data acquired in real time, judging whether the data is in a safe operation state or not andsending a corresponding processing signal to the control instruction module. The central controller is in communication connection with the lifting motor frequency converter, the variable-amplitude motor frequency converter and the rotary motor frequency converter to feed back and send out the control instruction, and the purpose of managing and controlling a tower crane lifting variable-amplitude and rotating angle integrated frequency converter is achieved.
