Cooperation executes a hard disk state display method refering to Fig. 3, disk state instruction device 5 of the present invention, simultaneously to every
One hard disk 3 carries out state judgement, and the implementation of the hard disk state display method comprises the steps of.
Firstly, step 20 is that the logic unit 52 receives first package, and judges institute according to the current potential of first package
Whether the corresponding hard disk 3 effectively exists.The step 20 includes following sub-step.
In sub-step 21, which receives first package.
In sub-step 22, which judges whether first package is low potential, if low potential then judges
The hard disk 3 is effectively to exist, and then execute step 23；If high potential, then sub-step 221 is carried out.
In sub-step 221, which exports hard disk 3 corresponding to the instruction and operates in invalid existence
Driving signal, and so that the corresponding display unit 4 is not shone, and repeat sub-step 21.
Then, step 23 is to receive second package corresponding to the hard disk 3 by the expansion unit 51, recognizes second envelope
It is surrounded by without exception, and generates one and be converted in pulse signal between one first logic level and one second logic level, and by the arteries and veins
Signal is rushed to export to the logic unit 52.Need herein supplement, due to the expansion unit 51 need to receive second package come
Abnormality judgement is made to corresponding hard disk 3, therefore, can more save and receive the entity electrical interconnection from the hard disk 3.
Then, step 24 is to be in the first logic level or the second logic standard according to the pulse signal by the logic unit 52
Position, to generate the display unit 4 that an instruction has driving signal without exception to the corresponding hard disk 3.If the pulse signal is in the
Two logic levels, then the logic unit 52 judges that the hard disk 3 operates in abnormality and then executes step 26；If the pulse is believed
Number be in the first logic level, then the logic unit 52 judge the hard disk 3 operate in normal condition and then execution step 25.
In step 26, which is in the second logic level, and the logic unit 52 is further by the pulse signal
Whether the first logic level is changing by the second logic level to judge that the hard disk 3 is in offline or mistake, if judging result
To be to then follow the steps 262, if judging result thens follow the steps 261 to be no.
Step 262: the logic unit 52 judges the pulse signal between the second logic level and the first logic level back and forth
Bounce, and the driving signal that the corresponding hard disk 3 of an instruction operates in off-line state is exported, make the corresponding emitting red light two
Pole pipe issues flashing feux rouges.
Step 261: the logic unit 52 judges that the pulse signal is held in the second logic level, and it is right to export an instruction institute
The hard disk 3 answered operates in the driving signal of error condition, and the corresponding red light emitting diodes is made to continuously send out feux rouges.
In step 25, which is in the first logic level, which further executes following sub-step
It is rapid to judge that the hard disk 3 is in idle or access.
Sub-step 251: the logic unit 52 starts timing first predetermined time using first timer.
Sub-step 252: the logic unit 52 judge the pulse signal whether be in the first logic level whether be up to this
One predetermined time if the determination result is YES then continued to execute sub-step 253；If judging result is no, repeatedly step 26.
Sub-step 253: the logic unit 52 receives the third package, and initialize second timer start timing this
Two predetermined times.
Sub-step 254: the logic unit 52 judges whether the third package has the pulse up to second predetermined time,
And in this example, which is the pulse positioned at the first logic level.If so, then continuing to execute sub-step 255；If nothing is jumped
To sub-step 256.
Sub-step 255: the logic unit 52 judges the third package to be second predetermined up to this in the first logic level
The pulse of time, and the driving signal that the corresponding hard disk 3 of an instruction operates in idle state is exported, make the corresponding green
Light emitting diode continuously sends out green light.
Sub-step 256: the logic unit 52 judges the third package between the first logic level and the second logic level
The pulse of bounce, and the driving signal that the corresponding hard disk 3 of an instruction operates in access status is exported, make the corresponding green
Light emitting diode issues flash green.
Refering to Fig. 4, aforementioned hard disk state display method is further illustrated by taking a state transition diagram as an example again in this, and at this
In example, enabling first logic level is logical zero, which is logic 1, the specification however this still visual each hard disk dispatches from the factory
Make opposite implementation, without being limited with this example.In addition, setting first predetermined time as 1.5 seconds, which is 0.5
Second.
As long as firstly, whether effectively existing first package of the instruction hard disk 3 is in high potential, no matter in any state
It all can directly indicate that corresponding hard disk 3 is to exist in vain, and make corresponding red light emitting diodes and green emitting two
Pole pipe does not shine.
Then, when first package is in low potential, then further judge whether the pulse signal is up in logical zero
1.5 seconds, if so, the corresponding hard disk 3 of judgement is in normal condition, and switch to this figure upper half, at this time only green emitting
LED lighting, and determine that the hard disk 3 is in idle or access by the third package is judged, if the third package has place
It is up to pulse in 0.5 second in logical zero, then indicates that the hard disk 3 is in idle state, and hold corresponding green LED
Supervention goes out green light；If the third package has the pulse being converted between logic 1 and logical zero, indicate that the hard disk 3 is in access shape
State, and corresponding green LED is made to issue flash green.
However, when first package be in low potential, and the pulse signal be in logic 1, then judge corresponding to it is hard
Disk 3 is in abnormality, and switchs to this figure lower half, and only red light emitting diodes shine at this time, and by judging the pulse
Signal come determine the hard disk 3 be in broken string or mistake, if the pulse signal be in logic 1, indicate the hard disk 3 be in mistake shape
State, and corresponding red light emitting diodes is made to issue feux rouges；If the pulse signal changes back and forth between logic 1 and logical zero,
It indicates that the hard disk 3 is in broken string state, and corresponding red light emitting diodes is made to issue flashing feux rouges.
It herein must be, it is emphasized that in the present embodiment, i.e., the convenient logic unit 52 determines that the hard disk 3 operates in normal shape
State and to start with third package and be parsed, however since whether the logic unit 52 still can preferentially judge the pulse signal
Decided whether to receive the third package up to 1.5 seconds in logical zero, jumps back to logic 1 again to avoid the pulse signal in parsing, because
This, as long as the pulse signal goes out time existing logic 1 again in 1.5 seconds, or after 1.5 seconds, then the logic unit 52 can immediately again
Determine that corresponding hard disk 3 is abnormality, and determines that the display unit 4 is made correspondingly to continuously send out feux rouges or flash red
Light.Also therefore, abnormality priority with higher during parsing, and when the hard disk 3 is wrong or broken string
State when generating, can preferentially parse so that user learns the situation whether current corresponding hard disk 3 is abnormal.
In conclusion disk state instruction device 5 of the present invention by the logic unit 52 by the expansion unit 51 wherein
The pulse signal of the corresponding hard disk 3 of one transmission port output, and come by first and second timer of the logic unit 52
By time cutting, and the invalid presence of corresponding hard disk 3, mistake, broken string, idle, five kinds of states of access can be parsed simultaneously,
Thus have the following advantages that.
One, identical hard disk number needs less transmission port, due to the present invention only need using the expansion unit 51 its
In a transmission port transmit the pulse signal, therefore, when being intended to simultaneously be monitored 24 hard disks, it is only necessary to which occupying should
The pulse signal transmission to the logic unit 52 is carried out succeeding state parsing by 24 transmission ports of expansion unit 51, because
This saves 48 transmission ports compared to known, so that remaining not used transmission port can accommodate other simply in turn
Logic circuit carry out R. concomitans, the service efficiency of the transmission ports such as this is substantially improved.
Two, come to carry out succeeding state parsing to hard disk 3 by the logic unit 52, so as to save with it is additional such as buffer
The route arrangement of logic judging circuit, and then while monitoring multiple hard disk 3 at the same time, is not susceptible to the situation of wiring error, this
Outside, since the logic unit 52 may be repeated burning, it ought be intended to change logic circuit at any time in test phase and this is aobvious
It when showing the logical relation of the corresponding each hard disk of unit 4, can also modify at any time, without being only capable of replacement hardware electricity as known
Road, thus the cost of entity circuit is saved, therefore the purpose of the present invention can be reached really.
A specific embodiment of the invention and embodiment are elaborated above in conjunction with attached drawing, but the present invention is not
It is limited to the above-described embodiment and examples, within the knowledge of those skilled in the art, this can also be not being departed from
It is made a variety of changes under the premise of inventive concept.
