1. A jumper control circuit, comprising:
a switch module used to electrically connect to a circuit loop where a power supply device and a power consumption device are located; the switch module has an ON state and an OFF state;
a power supply detection module used to be electrically connected between a positive electrode and a negative electrode of the power supply device, and to generate a fault signal when an output voltage of the power supply device exceeds a predetermined voltage range;
an impedance detection module electrically connected to the switch module; when a impedance of the power consumption device in the circuit loop is within a predetermined impedance range, the impedance detection module triggers the switch module to switch to the ON state; and
a fault processing module electrically connected to the switch module; when receiving the fault signal, the fault processing module triggers the switch module to switch to the OFF state.
