Automatic power supply running system for computer hard disk

Abstract

The invention relates to a system for computer harddisc to make auto power-on operation, solving the technical problem of making the harddisc able to carry out auto power-on operation if need be and otherwise completely stop operating and of being able to change the harddisc without switching off the computer, by making the system adopt plug-supporting serial harddisc and plug-supporting upper computer mainboard with serial harddisc interface. And the technical solution comprises: upper computer mainboard to provide communication interface and plug-supporting data interface with serial harddisc interface; data interface extension module to extend the number of the serial hardisc interfaces of the upper computer; harddisc control module to control the auto power-on operation of the computer harddisc; power supply switching module to control the power supply of each harddisc in a memory harddisc set; harddiscs, comprising independently operating system harddisc and plug- supporting auto power-on operating memory harddisc set; switching power supply, supplying stable DC power to the whole system. The invention can be used in the field of computer control.

Description

technical field [0001] The invention relates to a computer storage control system, specifically controls the automatic power-on operation of a computer hard disk according to the access requirement of the hard disk, and belongs to the field of computer control. Background technique [0002] The current general-purpose computer hard disk system is composed of multiple large-capacity hard disks installed in the computer case. When the hard disk interface is not enough, the hard disk interface can be increased by using an adapter card to reach the total number of hard disks that need to be installed. All hard disks are always powered on after booting. Even if the system does not access certain hard disks, these hard disks still need to run and wait for possible access by the system at any time. If the hard disk hibernation function is enabled, it is easy to cause hard disk loss in the case of multiple hard disks, so in many places the hard disks work for a long time, so the pow...

AI Technical Summary

Problems solved by technology

If the hard disk hibernation function is enabled, it is easy to cause hard disk loss in the case of multiple hard disks, so in many places the hard disks work for a long time, so the power consumption always exists, which will also reduce the service life of the hard disk; The number of internal fans also increases with the increase of the number of hard disks, which in turn increases the power requirements of the switching power supply. At the same time, more fans will also increase the amount of flying dust, and the stability of the system will decrease.

[0003] There is also a hard disk system that is a hard disk array cabinet connected through a 1394 interface or a USB interface. There are independent power supplies and fans in the hard disk array cabinet. Although this improves the stability of the system, in some applications, such as digital monitoring When recording, most of the time only one or a few hard disks are operated, but the system requires a large storage space, so the entire system must be powered on, which also causes a lot of waste of system resources and energy
