The present invention provides a remote control-based robot-assisted intelligent maintenance system. The system comprises a master end control platform module, a master end input signal acquisition and processing module, a signal transmission and communication module, and a slave end control execution module. The master end control platform module provides a platform and an operation environment in accordance with man-machine engineering for an operation by a remote control system master end remote operator. The master end input signal acquisition and processing module collects and processes motion data of an action instruction of the remote operator. The signal transmission and communication module transmits input data of a master operator collected by a master end and a processing result to a remote slave end. The slave end control execution module receives the data of the master end, then analyzes the data and drives a slave end robot execution mechanism to execute a corresponding action. According to the remote control-based robot-assisted intelligent maintenance system, a robot can be controlled remotely online in real time, the system is applicable to multiple operation environments that are inconvenient for people to perform tasks directly, and auxiliary maintenance tasks of the remote control intelligent maintenance system can be completed.
