Second display state of bright state, to represent hard disk no exceptions.
When hard disk at least one makes a mistake state, control unit 110 provides the low voltage level of for example, at least one
Rub-out signal FS_1 ~ FS_N at least one, and rub-out signal FS_1 of this at least one of low voltage level ~ FS_N can transmit
To the input with door 330 so that with the logical signal LS that door 330 also produces low voltage level.The logic of this low voltage level
Signal LS can be sent to the cathode terminal of the second light emitting diode 350 via the second buffer 310.
Owing to the logical signal LS of the cathode terminal of the second light emitting diode 350 is low voltage level, and the second light-emitting diodes
Running voltage VCC of the anode tap of pipe 350 is high-voltage level, and therefore the second light emitting diode 350 turns on, and in shinny shape
State, represents hard disk at least one generation abnormality.Consequently, it is possible to the first display unit configured by front panel 210
State shown by 120_1 ~ 120_N and the second display unit 140, can learn the connection corresponding to hard disk, work and mistake
Etc. state, can will effectively reduce the complexity of circuit design and the use cost of circuit, to increase the convenience used.
Due to identification code signal UIDS display mode and be the emphasis of the present invention, therefore second display unit 140 of Fig. 3
Do not show the mode of display identification code signal UIDS, but art has usual skill, should be by display logic
The enforcement aspect of the circuit of signal LS, and push away to obtain the enforcement aspect of circuit of identification code signal UIDS, therefore repeating no more.

First, before disk state display device 600 does not comes into operation, due to the 3rd light emitting diode 620 and the 4th
The anode tap of optical diode 640 and running voltage VCC of cathode terminal are all high-voltage level so that the 3rd light emitting diode 620
It is not turned on the 4th light emitting diode 640, also presents the 3rd display state and the 4th display state of OFF state.
When disk state display device 600 comes into operation, control unit 110 provides the working signal of high-voltage level
WS_1 ~ WS_N, and working signal WS_1 ~ WS_N can be sent to the 3rd light emitting diode 620 via the 3rd buffer 610.Now,
The anode tap of the 3rd light emitting diode 620 and running voltage VCC of cathode terminal are all high-voltage level, then the 3rd light emitting diode
620 are not turned on, and present the 3rd display state of OFF state, represent that the hard disk connection status with hard disk backboard is for being not connected with.
Then, after hard disk and hard disk backboard couple, connect signal CS_1 ~ CS_N and can be converted to low voltage level, and pass
Deliver to the cathode terminal of the 3rd light emitting diode 620.Working signal WS_1 ~ WS_ due to the anode tap of the 3rd light emitting diode 620
N is the cathode terminal of high-voltage level, and the connection signal CS_1 ~ CS_N of the anode tap of the 3rd light emitting diode 620 is low-voltage
Level, therefore the 3rd light emitting diode 620 turns on, and presents the 3rd display state of lightened state, to represent hard disk and hard disk
Backboard is really for the connection status connected.
It addition, when hard disk is started working, control unit 110 can provide the working signal WS_1 ~ WS_N of pulse wave form, also
I.e. continuous print high-voltage level and low voltage level working signal WS_1 ~ WS_N alternately, and this working signal WS_1 ~ WS_N meeting
It is sent to the cathode terminal of the 3rd light emitting diode 620.
Now, owing to the working signal WS_1 ~ WS_N of the anode tap of the 3rd light emitting diode 620 is pulse wave form, and the
The connection signal CS_1 ~ CS_N of the cathode terminal of three light emitting diodes 620 is low voltage level, therefore the 3rd light emitting diode 620
Can turn on continuously and be not turned on alternately, to present the 3rd display state of flicker state, represent that hard disk operational is normal and carries out
The action of data access.
Then, owing to all hard disks all do not make a mistake, therefore control unit 110 can provide the mistake letter of high-voltage level
Number FS_1 ~ FS_N.Rub-out signal FS_1 of this high-voltage level ~ FS_N can be sent to the 4th via the 4th buffer 630 respectively
The cathode terminal of light emitting diode 640.
Owing to the FS_1 ~ FS_N of the anode tap of the 4th light emitting diode 640 is high-voltage level, and the 4th light emitting diode
Running voltage VCC of the cathode terminal of 640 is high-voltage level, and therefore the 4th light emitting diode 640 is not turned on, and it is bright to present extinguishing
4th display state of state, to represent hard disk no exceptions.
When hard disk at least one makes a mistake state, control unit 110 provides the low voltage level of for example, at least one
Rub-out signal FS_1 ~ FS_N at least one, and rub-out signal FS_1 of this at least one of low voltage level ~ FS_N can be via
4th buffer 630 is sent to the cathode terminal of the 4th light emitting diode 640.
Owing to rub-out signal FS_1 ~ FS_N at least one of the cathode terminal of the 4th light emitting diode 640 is low voltage level,
And running voltage VCC of the anode tap of the 4th light emitting diode 640 is high-voltage level, therefore the 4th light emitting diode 640 to
Few one conducting, and in lightened state, represent hard disk at least one generation abnormality.
Consequently, it is possible to user can be by the state shown by the configured display unit of front panel 210, or simultaneously by front
The state shown by display unit that panel 210 and backplate 510 are configured, can learn the connection corresponding to hard disk, work
And the state such as mistake, to increase the convenience used.
Due to identification code signal UIDS display mode and be the emphasis of the present invention, therefore second display unit 140 of Fig. 6
Do not show the mode of display identification code signal UIDS, but art has usual skill, should be by display logic
The enforcement aspect of the circuit of signal LS, and push away to obtain the enforcement aspect of circuit of identification code signal UIDS, therefore do not repeat them here.Separately
Outward, Fig. 6 does not also show the new display unit on backplate 510, in order to show the enforcement of the circuit of identification code signal UIDS
Aspect, but art has usual skill, by the enforcement aspect of the circuit of display logic signal LS, and should push away to obtain the back of the body
The enforcement aspect of the circuit of the new display unit of panel 510, therefore do not repeat them here.
The disk state display device of embodiments of the invention, it produces corresponding working signal with wrong by control unit
Error signal, recycles the first display unit and shows that corresponding first shows according to working signal with connecting the voltage level of signal
State, the second display unit show the second display state of correspondence, wherein the first display according to the voltage level of rub-out signal
Unit and the second display unit are configured at the front panel of electronic installation.
It addition, also can further in electronic installation backplate backplate configuration the 3rd display unit with the 4th display singly
Unit, and the 3rd display unit show according to working signal and the connection voltage level of signal corresponding the 3rd display state, the
Four display units show the 4th display state of correspondence according to the voltage level of rub-out signal.Consequently, it is possible to can effectively reduce
Circuit design and the complexity of layout and the use cost of circuit, and can be by front panel or by front panel and backplate institute
