The invention discloses a remote control system for a frequency converter, and relates to the technical field of operation control of tower cranes, the system collects key data of a suspension arm or a lifting hook in real time through inertial swing monitoring points arranged by a region division module, and constructs and evaluates an inertial swing risk index IB by combining acceleration and deceleration parameters of the frequency converter and load weight changes; and generating a first control strategy to reduce the swing risk. The second alarm module further combines wind speed and dynamic load change multi-dimensional data analysis, optimizes the first control strategy, generates a second control strategy, and improves the response capability to emergencies. The compensation evaluation module dynamically evaluates the compensation precision and optimizes the control strategy by monitoring the torque and slip state of the frequency converter, thereby reducing the error and improving the system precision. In general, the safety and the stability in the lifting process are improved, and the operation risk caused by external factors such as load fluctuation and wind speed change is remarkably reduced.
