In order to simultaneously control the startup and operation of the plurality of power sources, and integrate the output power of the power sources, the backup power system further includes a backplane connecting the power sources, and the backplane has integrated power source outputs. The current path and the signal path of the transmitted signal.

Although the backup power system can continue to supply power when some of the power sources are damaged or briefly powered off to maintain the load system operation. However, in the event of a long-term power outage or natural disaster, the entire power system may be shut down. Because the entire power system is shut down, even after the commercial power is restored, the entire backup power system cannot start the power supply by itself, causing trouble for the maintainer. It also causes an empty window period in which the load system cannot operate.

The related case, such as the Republic of China Patent Notice No. 575846 "Environmental Protection, Control and Management System for Unmanned Computer Rooms" provides an unmanned environment management system with An ECM security subsystem, and the ECM security subsystem includes a smart slot, and the smart slot is combined with the network card, and the ECM security subsystem can be controlled from the remote end through the connection of the smart slot and the network.

Each of the power lines 94 is provided with a remote start switch 940, and each of the loads 93 has a remote start signal line 95. The user triggers the load 93 to output a remote start signal through the remote start signal line 95 to drive the remote start switch 940 to be turned on, and simultaneously wake up the power supply 91 to output power.

It is known from the prior art that the remote start switch 940 on the power supply line 94 is directly controlled by the remote start signal output by the loads 93. Moreover, the power supplies 91 are also awake through the remote start signals. Therefore, after a long-term power outage or a natural disaster, the power supply 91 cannot resume operation after the power is restored, and the system maintainer needs to be present in person, causing a lot of inconvenience.

Based on the aforementioned conventional problems, the purpose of the present invention is to improve the conventional problems, so that the system can restore the basic power supply capacity after the commercial power source resumes power supply.
