Specifically, the first voltage is the voltage of the power bus before power failure; the second voltage is the voltage of the power bus after power failure; each load corresponds to a group of direct current load data, and the direct current load data comprises data such as discharge duration, load current and the like. The discharge duration is the continuous discharge duration corresponding to the load during working, and the load current can be obtained based on the power and voltage calculation of the load, and can also be obtained by direct measurement.

And finally, selecting power supply equipment corresponding to the discharge characteristics by combining the discharge characteristics corresponding to each type of load.
The preset discharge duration threshold is related to the application scene, and the corresponding preset discharge duration thresholds in different scenes are different. The preset discharge time threshold is the discharge time required for starting/stopping certain loads after power failure to ensure the safety of the equipment. If the application scene is a reservoir, if the reservoir gate needs to be opened to discharge water, the reservoir gate needs to be closed to ensure the safety of life and property when a power failure occurs, and because the reservoir gate needs to be closed for 15-20 seconds, in this embodiment, the preset discharge time threshold can be set to 25 seconds.
