Voltage monitor fault self-diagnosis method and system based on Internet of Things

The invention relates to a voltage monitor fault self-diagnosis method and system based on the Internet of Things. The method comprises the steps that a monitor fault type database including a plurality of fault types of a voltage monitor and a monitor fault processing scheme database including corresponding fault type processing schemes are preset and stored; corresponding fault types are selected from the fault type database one by one, and corresponding early warning modes are matched; and obtaining an early warning mode sent in the working process of the voltage monitor to determine a corresponding fault type, selecting a corresponding processing scheme from a monitor fault processing scheme database, and sending the corresponding processing scheme to an operator. According to the invention, the specific fault reason of the voltage monitor can be diagnosed in real time, a corresponding processing scheme is provided, and the damage of the voltage monitor is reduced. 本发明涉及一种基于物联网的电压监测仪故障自诊断方法及系统，其包括预设存储有包括电
