The invention provides a general monitoring system for a middle-low voltage power electronic control device. The general monitoring system for the middle-low voltage power electronic control device comprises a configuration setting unit, a real-time data processing unit and a real-time debugging and monitoring unit, wherein the configuration setting unit and the real-time data processing unit preform data interaction via a file transfer protocol (FTP); and the real-time debugging and monitoring unit reads configuration parameters of the configuration setting unit and performs data interaction with the real-time data processing unit via an ethernet network. The general monitoring system for the middle-low voltage power electronic control device has a reasonable structure and also can provide general monitoring suitable for the middle-low voltage power electronic control device.
