Embodiment
Refer to Fig. 1, better embodiment of the present invention provides a kind of indicator lamp control system 100, and it is applied on hard disk (hard disk drive, the HDD) backboard 1 of an electronic installation.This indicator lamp control system 100 can run after this electronic apparatus system starts, and namely runs after start.This indicator lamp control system 100 is for controlling a pilot lamp 10.This indicator lamp control system 100 comprises this pilot lamp 10, CPLD (Complex Programmable Logic Device, CPLD) module 20, integrated south bridge (Platform Controller Hub, PCH) module 30, Basic Input or Output System (BIOS) (Basic Input Output System, BIOS) module 40 and impact damper 50.Wherein, this pilot lamp 10, CPLD module 20 and impact damper 50 are arranged on this HDD backboard 1, and this PCH module 30 and BIOS module 40 are arranged on the mainboard 2 of this electronic installation.
This pilot lamp 10 one end is electrically connected at a power supply P3V3 by one first resistance R1, and the other end is electrically connected at this impact damper 50.In the present embodiment, this pilot lamp 10 is a light emitting diode, and its anode is electrically connected at this power supply P3V3 by this first resistance R1, and its negative electrode is electrically connected at this impact damper 50.This pilot lamp 10 is used to indicate the state that reports an error of the HDD of a correspondence of access on this HDD backboard 1.When this HDD occurs abnormal, this pilot lamp 10 is bright state; When HDD is normal condition, the state of this pilot lamp 10 for going out.
This CPLD module 20 comprises the control pin LED controlled pilot lamp 10, and this control pin LED is electrically connected at this pilot lamp 10 by this impact damper 50.When on this HDD backboard 1, the HDD of a correspondence of access occurs abnormal, such as because of the connector bad connection of HDD and HDD backboard 1, and cause and the situation that HDD is not in place detected, this CPLD module 20 sends one by this control pin LED and controls signal to this pilot lamp 10, and the state of pilot lamp 10 is brightened by going out.Be appreciated that this CPLD module 20 no longer transmits control signal, and the state of pilot lamp 10 is then gone out by bright change when this HDD recovers normal.
The universal input that this PCH module 30 comprises impact damper 50 controls exports (General Purpose Input Output, GPIO) pin, and this GPIO pin is electrically connected at this impact damper 50 by one second resistance R2.This GPIO pin be used for output enable control signal to this impact damper 50, with control this impact damper 50 conducting or by state.
This BIOS module 40 is electrically connected at this PCH module 30, writes output level, to control the output level of GPIO pin for the register corresponding in this GPIO pin.In the present embodiment, to before entering operating system after this electronic apparatus system starts, this BIOS module 40 is to this GPIO pin write high level; After this electronic installation enters operating system, this BIOS module 40 is to this GPIO pin write low level.
This impact damper 50 comprises the first pin P1, the second pin P2, the 3rd pin P3, the 4th pin P4 and the 5th pin P5.This first pin P1 is electrically connected at this GPIO pin by this second resistance R2, and this first pin P1 is enable control pin.This second pin P2 is electrically connected at this control pin LED.3rd pin P3 is electrically connected at this pilot lamp 10, is also electrically connected at this power supply P3V3 by one the 3rd resistance R3.4th pin P4 is electrically connected at a power supply P5V, also by an electric capacity C1 ground connection.5th pin P5 ground connection.When this first pin P1 receives a high level, this impact damper 50 by, now this pilot lamp 10 does not control by this CPLD module 20; When this first pin P1 receives a low level, this impact damper 50 conducting, now this pilot lamp 10 returns to and controls by this CPLD module 20.
Before entering operating system after this electronic apparatus system starts, this BIOS module 40 writes high level to the register that this GPIO pin is corresponding, this PCH module exports the first pin P1 of a high level to this impact damper 50 by this GPIO pin, now this impact damper 50 ends, this pilot lamp 10 does not control by this CPLD module 20, thus makes this pilot lamp 10 be in the state of going out always.After this electronic installation enters operating system, this BIOS module 40 writes low level to the register that this GPIO pin is corresponding, this PCH module exports the first pin P1 of a low level to this impact damper 50 by this GPIO pin, now this impact damper 50 recovers conducting, and this pilot lamp 10 returns to and controls by this CPLD module 20.In the operation of operating system, this pilot lamp 10 can indicate the state of the HDD of a correspondence of access on this HDD backboard 1, when the HDD of this correspondence occurs abnormal, this CPLD module controls pin LED by it and outputs control signals to pilot lamp 10, to make pilot lamp 10 brighten, thus play the effect reported an error.
This indicator lamp control system 100 electronic device startup to enter operating system during this period of time in, end by controlling this impact damper 50, pilot lamp 10 is made to be in the state of going out, avoid the situation that pilot lamp 10 lights by mistake in electronic device startup process, make the indicating status of pilot lamp 10 more accurate.
Although be illustrated the preferred embodiment of the present invention and describe, the art personnel will realize, and can make different changes, and these do not exceed scope of the present invention.Therefore expect, the present invention is not limited to disclosed as the preferred forms realized contemplated by the present invention.
