The invention relates to a high-voltage interlocking detection circuit. The high-voltage interlocking detection circuit comprises a constant current source, a first voltage detection module and a resistor module. The first end of the first voltage detection module is connected with the output end of the constant current source; the first end of the resistor module is connected with the second end of the first voltage detection module and the first end of the high-voltage interlocking module, and the second end of the resistor module is connected with the second end of the high-voltage interlocking module; wherein the third end of the first voltage detection module is used for outputting a first voltage signal, and the first voltage signal is used for representing the on-off state of the high-voltage interlocking module. By adopting the circuit, the on-off state and the resistance of the high-voltage interlocking module can be detected, and the complexity and the design cost of the high-voltage interlocking detection circuit are remarkably reduced.
