Embodiments of the present disclosure relate to the field of power supply and distribution in a data center, and more specifically, to a power supply control apparatus and a method for controlling power supply.
Power distribution of an information technology (IT) cabinet located in a data center is generally as follows: dual mains power supply is connected, and the mains power supply enters a mains distribution box, where a part of the mains power supply is supplied to an air conditioner, lighting, and a common socket, and the other part is supplied to an uninterruptible power supply (UPS). As shown in
The front-end switches of the cabinet may be integrated into a power distribution cabinet, or may be distributed in independent plug-in units. The cabinet needs to acquire power from the front-end switch of the cabinet. However, because the front-end switch of the cabinet has a fixed switch capacity, power distribution to the cabinet is inflexible. In particular, when a capacity of the switch is unadaptable because of a power change of the cabinet, a switch and a power cable need to be replaced, and therefore, a large engineering workload is caused.
Embodiments of the present disclosure provide a power supply control apparatus and a method for controlling power supply, which can adjust a capacity of a switch and enhance power distribution flexibility.

The described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
In addition, dynamic environment monitoring of an equipment room is another independent system. As shown in
That is, for monitored parameters of an equipment room, after collecting all monitored parameters in a centralized manner, one or more collectors report all the monitored parameters. The collector needs to be connected to multiple monitoring components that vary in distance, and the connection is a wired connection, which leads to a large quantity of cables in wired connection engineering and complex cabling.
The communications module 301 is configured to receive an instruction of a network management center 100. The controllable switch 302 is configured to adjust a capacity of the controllable switch according to the instruction to perform power-on/power-off control on the cabinet.
In this embodiment of the present disclosure, a power supply control apparatus may receive an instruction of a network management center, and can adjust a capacity of a controllable switch according to the instruction, which enhances power distribution flexibility, and can reduce a workload of replacing a switch and a power cable, thereby avoiding an engineering related risk.

Optionally, the network management center may be a server of the data center, and may be manually configured, operated, and the like.
The communications module 301 may communicate with the network management center 100 in a wireless manner. In this case, connection is performed without a cable, which can reduce a quantity of cables.
In this embodiment of the present disclosure, a rated value of a capacity of an input switch of the cabinet may be set in the network management center 100, and the controllable switch 302 adjusts the capacity of the switch using the instruction passed through the communications module 301. In this way, a problem of a fixed capacity of a switch in the prior art can be resolved, and an adjustable capacity of the switch can be implemented, which enhances power distribution flexibility and avoids an engineering related risk.
For example, a rated power supply current of the cabinet may be set in the network management center 100, where the current may be of different values such as 10 amperes (A), 16A, 20A, 25A, 32A, 40A, 50A, and 63A. In this case, monitoring and control of power supply to an equipment room can be implemented by monitoring and controlling the power supply current of the cabinet in the network management center 100.
