Title:
DUAL-POWER SWITCHING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/032047
Kind Code:
A1
Abstract:
The present invention provides a dual-power switching apparatus and method. The dual-power switching apparatus comprises: a power-frequency circuit that outputs power-frequency power; a UPS circuit that outputs UPS power; and a control unit used for switching to the power-frequency circuit or the UPS circuit for power output, so as to output the power-frequency power or the UPS power to a transmitter. The control unit is used for controlling the power-frequency circuit to continuously output the power-frequency power to the transmitter, monitoring in real time whether the power-frequency circuit fails, and if the power-frequency circuit fails, switching to the UPS circuit to output the UPS power to the transmitter. The control unit is further used for switching, after detecting that the UPS circuit fails, to the power-frequency circuit to output the power-frequency power to the transmitter. According to the present invention, a power-frequency circuit and a UPS circuit are provided to implement dual power supply, and real-time switching between two power supplies is performed by determining a failed circuit, so that when a UPS fails or does not meet the power supply requirements, the power supply can be switched in time to effectively prevent a DCS device from being burned, thereby ensuring the safety of the device.
