Embodiment Construction

[0023] figure 1 It is a schematic structural diagram of a power supply device provided by an embodiment of the present invention. Such as figure 1 As shown, the power supply device includes: a supercapacitor 11 , a battery 12 , a control circuit 13 , a power failure detection circuit 14 and a notification unit 15 .

[0024] The power failure detection circuit 14 is used to detect whether the main power supply of the storage system is powered off or whether it is powered on after the power failure.

[0025] The control circuit 13 is connected with the supercapacitor 11, the battery 12 and the power failure detection circuit 14, and is used to control the discharge of the supercapacitor 11 when the power failure detection circuit 14 detects that the main power supply of the storage system is powered off, so as to serve as the main power supply of the storage system. The control board supplies power; the control circuit 13 is also used to control the battery 12 to supply power ...

Abstract

The invention provides a power supply device, a storage system and a power supply method. A super capacitor is controlled for supplying power to a main control panel of the storage system through a control circuit under the condition that a main power supply of the storage system is in power failure, in addition, when the discharging of the super capacitor reaches the preset duration, batteries are controlled for supplying power to the main control panel of the storage system, the key data storage completion of the storage system can be ensured after the main power supply of the storage system is in the power failure, in addition, the battery discharging after the main power supply of the storage system is in the power failure is possibly avoided, and the charging times of the batteries is reduced, so the service lives of the batteries are effectively prolonged.

Description

technical field [0001] The invention relates to power supply technology, in particular to a power supply device, a storage system and a power supply method. Background technique [0002] With the rapid development of computer technology and network technology, the built-in memory of the computer is gradually difficult to meet many requirements such as fast access speed, large storage capacity and low cost, so a relatively independent storage system has been developed. The storage system usually includes a main control board and an external hard disk, which has its own interface and protocol, and is connected to the computer host or server through coaxial cables, network cables, optical fibers, etc., and serves as a data storage center to provide storage services for the host. [0003] When the main power supply fails, the storage system needs to save the cached data of user services and key system data in the system memory in time. When the storage system is saving data due...
