Embodiment Construction

[0061]In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 As shown, the embodiment of the present invention provides a power supply system 10. The power supply system can be an urban traffic power supply system, a home power supply system, or a security power supply system. The power supply system 10 includes:

[0063] UPS 11 , time-sharing power manager (also called time-sharing controller) 12 and at least two load devices 13 .

[0064] The input end of UPS11 is connected to the mains power supply network, and the time-sharing power manager 12 is connected to UPS11 and at least two load devices 13 respectively. The mains power supply network typically outputs electrical signals at a voltage of 220 volts (V).

[0065] UPS usually includes a voltage stabilizer and a fi...

Abstract

The invention discloses a power supply system and a control method thereof, and belongs to the field of power supply and distribution. The power supply system comprises an uninterruptible power supply(UPS), a time-sharing power manager and at least two load devices, wherein the UPS is connected with a commercial power supply network, the time-sharing power supply manager is connected with the UPSand at least two load devices, and the time-sharing power manager is used for controlling the UPS to perform time-sharing output of the electric signals on the at least two load devices based on theload control parameters of the at least two load devices when the commercial power supply network has no electric signal output. The load control parameters comprise at least one kind of device energyconsumption, device types and device priorities. The electric signals are output to the at least two load devices in a time-sharing manner without continuously supplying power to all the load devicesat the same time, so that the power supply flexibility of the power supply system is improved.

Description

technical field [0001] The invention relates to the field of power supply and distribution, in particular to a power supply system and a control method thereof. Background technique [0002] The security technology protection system is a protection system that can provide security services for a specific place. For example, the specific place is a self-service bank branch. The system is usually equipped with an uninterruptible power supply (English: Uninterruptible Power Supply; UPS for short). In the event of a power outage, continue to supply power to the safety technology protection system. [0003] At present, UPS can be connected with all load devices in the security technology protection system separately, and supply power to all loads at the same time after the mains power is cut off. [0004] However, since the power supply requirements of each load are different after the mains power is cut off, continuous power supply to all loads may cause some load devices with ...
