Emergency release power supply circuit and device

The application relates to an emergency brake release power supply circuit and equipment. The circuit comprises a control module, a switching component, a first power supply circuit and a second power supply circuit; the control module turns on the connection between the first power supply circuit, the second power supply circuit and the corresponding interface equipment through the switching component, so that, in the case of normal power supply, the control module controls the first power supply circuit to supply power to the equipment standby battery, and in the case of monitoring the corresponding signal, the control module controls the first power supply circuit to provide power supply for the equipment control system, and controls the second power supply circuit to supply power to the brake holding coil; in the case of abnormal power supply, if the corresponding signal is monitored, the equipment standby battery provides power supply for the equipment control system through a DC-DC converter, and the control module controls the first power supply circuit to supply power to the brake holding coil through the switching component. Thus, the application simplifies the circuit, realizes the cost reduction through the reuse and normalization of the circuit.
