Embodiment Construction

[0047] In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will first be described below.

[0048]After studying the light-emitting mode of the traditional hard disk indicator light, it is found that some hard disks have an indicator light, which is used to indicate the hard disk status of the hard disk. The indicator light is controlled by the control signal. The high and low levels of the control signal can control the indicator light to be turned on or off. see Figure 1A and Figure 1B As shown, this figure is a schematic diagram of two kinds of hard disk backplane indicator light control circuits respectively provided in the embodiments of the present application. in, Figure 1A The CPLD (Complex Programmable Logic Device, Complex Programmable Logic Device) in the LED is directly connected to the indicator light, and can only control t...

Abstract

The embodiment of the invention discloses a hard disk indicator light control circuit, method and equipment, the circuit comprises a central processor, a complex programmable logic device, a switch control chip and a hard disk indicator light, and the hard disk indicator light comprises a first color indicator light and a second color indicator light; the central processor is connected with the complex programmable logic device, the complex programmable logic device is connected with the switch control chip, and the output enabling end of the switch control chip is connected with the hard disk indicator light. An indicator light control signal is generated based on a state indication signal sent by the central processor through the complex programmable logic device, and then the hard disk indicator light is controlled through the switch control chip to adjust the light emitting state. Thus, the on-off state of the output enabling end of the switch control chip can be controlled, the hard disk indicator light is controlled to flicker, and the light-emitting state of the hard disk indicator light is increased.

Description

technical field [0001] The present application relates to the field of control technology, in particular to a hard disk indicator light control circuit, method and equipment. Background technique [0002] The computer hard disk is an important storage device of the computer, and some computer hard disks are designed with hard disk indicators. The hard disk indicator is used to indicate the hard disk status of the current hard disk. The user can determine the current hard disk status of the hard disk through the hard disk indicator light. [0003] At present, the light-emitting mode of the hard disk indicator light is relatively single, and it cannot comprehensively reflect all the states of the hard disk through different light-emitting modes. As a result, the user cannot determine the status of the hard disk based on the hard disk indicator light. Contents of the invention [0004] In view of this, the embodiments of the present application provide a hard disk indicato...
