Abstract
The invention provides grounding safety control point monitoring method, measuring circuit and equipment grounding measuring system, wherein, The grounding safety control point monitoring method comprises the following steps: A safety monitoring level signal corresponding to each circuit is output according to the comparison result of the voltage between the grounding safety control points of at least one circuit and the preset grounding safety standard voltage; one circuit of safety action level signal is adjusted and output according to at least one circuit of input safety monitoring level signal; grounding safety protection is done according to the safety action level signal. All grounding points are monitored in real time by comparing the voltage between grounding safety control points with preset grounding safety standard voltage, so as to guarantee the product safety, equipment safety and personal safety.
