The problem that the service time of each load is unreasonable and leads to that has solved current variable frequency speed control system exists is solved. The method comprises the following steps: monitoring and recording the total running time of each load in the system; when the total running time of a certain load is close to the overhaul time limit of the load, sending out use overdue early warning information and a load replacement command; the load replacement command comprises information of a load to be replaced; monitoring and recording the current running time of each load in the system, and sending a load replacement command when the current running time of a certain load exceeds the rated continuous running time of the load; when a load replacement command is detected, a replaceable device of the load to be replaced is selected as a standby device, and the load to be replaced is replaced to continue working. The invention has the characteristic of strong transplanting capability and can be applied to variable-frequency speed-regulation multi-load systems of various processes.)
