Instruction information accidentally.
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
In the prior art, in order to improve problem above, the read-write indication signal that hard disk exports is handled using CPLD.
When CPLD determines hard disk in place and read-write indication signal is square wave, the square wave that CPLD exports fixed frequency drives indicator light,
Control instructions lamp is flashed.When CPLD determines that hard disk is in place and read-write indication signal is there is no changing, it is believed that hard at present
Disk is not written and read, and control instructions lamp is always on.In general, judging read-write from square wave change in the prior art
Change to constant level needs and waits for a period of time.But in order to be suitable for the disk read-write indication signal of different frequency flashing, lead to
Longer time, such as 1 second should be often set as " a period of time ".It will lead to for all hard disks, after the completion of read-write, i.e.,
The read-write indication signal of hard disk is set to revert to constant level, the indicator light of CPLD connection can also flash a period of time more, be easy to make
At the misunderstanding of technical staff.
Therefore, the application provide it is a kind of read and write indicator light control method, by when read and write indication signal jump when,
The waiting time is determined according to the hop period of the level jump, that is, determines the signal intensity period, when read-write indication signal becomes
Change faster when, can be judged using the shorter signal intensity period, when read and write indication signal variation it is longer when, can be with
Judged using the longer signal intensity period, shortens the waiting time for becoming constant level again from flashing, avoid and pass out
A possibility that instruction information of mistake, reduction is misread.
Referring to FIG. 1, Fig. 1 is a kind of flow chart for the control method for reading and writing indicator light provided by the embodiment of the present application.
In the present embodiment, this method may include:
S101 believes according to predeterminated frequency to read-write indicator light output square wave when reading and writing indication signal generation level jump
Number；
This step is intended to export square-wave signal when read-write indication signal jumps.When read-write indication signal is jumped
When change, mean that hard disk enters read-write state at this time, answers control instructions lamp to be flashed at this time, to show that hard disk enters read-write
State.
And in the prior art, the flicker cycle that indication signal is read and write between different hard disks is not identical.In order to unified different
The instruction difference of hard disk, reduces the possibility being misunderstood, in this step when read-write jumps, i.e., defeated according to predeterminated frequency
Square-wave signal out.Wherein, predeterminated frequency is preset unified frequency.As it can be seen that no matter reading and writing what indication signal jumped
Gap between hop period is how many, can export identical square-wave signal by this step, unify instruction standard, subtracted
A possibility that being misunderstood is lacked.
Wherein, level jump refers to that level signal becomes low level from high level, or becomes high level from low level.It can
See, as long as changing by the level for reading and writing indication signal in this step the present embodiment, corresponding side is exported to indicator light
Wave signal, to show in time, hard disk is in read-write state at this time.
S102 determines the signal intensity period according to the hop period of level jump；
On the basis of S101, this step is intended to determine the signal intensity period according to the hop period jumped.Due to
The flicker cycle of the read-write indication signal of different hard disks is not identical, it is therefore desirable to determine carry out state according to different flicker cycles
Convert waiting time, that is, signal intensity period.
In the present embodiment, high level is mainly kept by judgement read-write indication signal or keeps low level duration, if
Greater than preset duration, so that it is determined that whether hard disk has exited read-write state.
Wherein, hop period refers to that read-write indication signal is separated by the duration of level jump twice.When this level twice
Jump is when being separated by flash signal twice in read-write indication signal, and hop period is to read and write the flicker cycle of indication signal
Half.It is also possible to there is level jump twice, it is respectively occurring at the ending of signal flashing, a signal flashing is opened
Begin, hop period is the interval of signal flashing twice at this time.
It, can be with it is envisioned that if the hop period got in this step has inaccuracy
Hop period is judged, to filter out suitable hop period, and then is determined more accurately further according to the hop period
The signal intensity period.
S103, when the duration of any one level jump is greater than the signal intensity period, to read-write indicator light output
Permanent level signal.
On the basis of S102, this step is intended to be greater than signal intensity when the duration for any one level jump occur
When the period, permanent level signal is exported to indicator light, i.e., the flashing state of indicator light is reverted into normal condition.
As it can be seen that the signal intensity period in the present embodiment is changed according to the hop period of read-write indication signal.Also
It is when hop period is elongated, the signal intensity period is elongated accordingly.When hop period shortens, the signal intensity period is corresponding
It shortens.It reduces from flashing state and restores the time to be waited to normal condition, the flashing for avoiding indicator light excessive causes display not
Accurate situation.
And the prior art be judged using preset fixed duration, that is, no matter the display cycle of the indication signal
What is, is all made of fixed duration and is judged.Also, the prior art, generally will fixed duration in order to adapt to the different periods
What is be arranged is longer, for example, 1 second or 2 seconds.Therefore, when read-write indication signal has reverted to permanent level signal, the prior art
In indicator light can also more flashing a period of times, it is 2 seconds a length of when fixed for example, will be flashed 1 second when a length of 1 second when fixed more
When, it will flash 2 seconds more.But the working condition of hard disk changes at any time, in the time of extra flashing, hard disk has can
Other processing can be had been carried out, or restart to be written and read processing, indicator light continues to flash.For operator
For member's observation, indicator light does not change at this time, that is, misses the state displaying of permanent level.
To sum up, the present embodiment is determining etc. according to the hop period of the level jump when read-write indication signal jumps
To the time, that is, determine the signal intensity period.When read and write indication signal variation faster when, can be become using shorter signal
Changing the period is judged, when read and write indication signal variation it is longer when, can be judged using the longer signal intensity period.
The waiting time for becoming constant level again from flashing by shortening, the instruction information that transmitting makes mistake is avoided, reduction is misread
A possibility that.
Below by way of three embodiments, to how determining that the signal intensity period is illustrated.
A kind of embodiment:
Referring to FIG. 2, Fig. 2 is a kind of signal intensity period method of determination in control method provided by the embodiment of the present application
Flow chart.
S201 obtains the hop period of read-write indication signal；
S202, judges whether hop period is less than or equal to threshold value；If so, executing S203；If it is not, then executing S204；
Hop period is added with redundancy duration, obtains the signal intensity period by S203；
S204, using preset duration as the signal intensity period.
As it can be seen that being the hop period for getting read-write first in the present embodiment, whether the hop period is then judged
Effectively, avoid getting the hop period of mistake.Finally, hop period is added with redundancy duration, increase certain error amount,
Situations such as preventing erroneous judgement.
It is envisioned that the redundancy duration is less than hop period, and redundancy duration is kept to will not influence normal letter
Signal lamp flashing.For example, redundancy duration can be 0.5S at this time when the hop period got is 0.25S.
Optionally, the S201 of the present embodiment may include:
When reading and writing indication signal generation level jump, the duration of recording level jump, using duration as jump
Variable period.
As it can be seen that this optinal plan provides a kind of mode for obtaining hop period, when mainly being continued by recording it
It is long, and using duration as hop period.
Optionally, the S201 of the present embodiment also may include:
When reading and writing indication signal generation level jump, start timing；
When again level jump occurs for read-write indication signal, terminates timing, obtain clocking value；
Using clocking value as hop period.
As it can be seen that this optinal plan provides another mode for obtaining hop period, mainly by way of timing
Obtain hop period.
The present embodiment gets hop period by the way of directly judging read-write indication signal, improves jump week
The accuracy rate that phase obtains, and acquisition speed is timely.When read-write indication signal jumps, so that it may get jump week
Phase, and the corresponding signal intensity period is calculated, it is directly used in and reduction, which is prolonged, to be judged to the level jump of read-write indication signal
Late, judging efficiency is improved.
For being controlled using CPLD indicator light, the overall plan of the present embodiment is illustrated.
The present embodiment drives indicator light using CPLD.The read-write indication signal of hard disk is connect to CPLD, and by CPLD
Output read-write indication signal is for directly driving indicator light after reason.The signal in place of hard disk is sent to CPLD simultaneously, and CPLD may be used also
To be attached by I2C (Inter-Integrated Circuit) bus and external controller.
CPLD, which is exported, reads and writes indication signal from switch extraction to the output of indicator light, and the signal source of switch has two
It is a, one be square-wave generator 1/2/3 signal, square-wave generator 1/2/3 generate frequency be 0.5Hz, the side of 1Hz, 2Hz respectively
Wave.When switch is switched to this all the way, square-wave signal meeting control instructions lamp is flashed according to specific frequency；Another two are in place
On signal, when switch switches to this all the way, if hard disk in place if lamp it is bright, if hard disk indicator light not in place extinguishes.
In addition, switch needs a control signal, it is that output square-wave signal or hard disk are in place for controlling switch
Signal.The control signal is obtained from timer 1.In output read-write indication signal default connection to hard disk signal in place.From hard
The input read-write indication signal that disk attracts is connected to timer 1, and timer 1 constantly carries out timing, when instruction letter is read and write in input
When number level jump occurs, timer 1 resets clocking value, and switch is switched to square-wave signal, allows output read-write instruction letter
It number is connected on square-wave signal；After timing is to the signal intensity period, switch is switched to hard disk signal in place, that is, permanent
Level signal makes to read and write the state that indicator light holding is always on.Realize that output read-write refers to when input read-write indication signal is square wave
Show that signal is the square-wave signal of specific frequency；When input read-write indication signal is constant level, output read-write indication signal
It is constant level.
Wherein, the timing predetermined time of timer 1 can be calculated by timer 2, comparator, arithmetic unit, be set.
Input read-write indication signal is connected to timer 2, and timer 2 carries out timing, when jumping input read-write indication signal,
The clocking value between adjacent jump twice is just sent to comparator.Comparator compares this clocking value and threshold value, when
It is not acted when greater than threshold value, when being less than threshold value, present timing value is issued into arithmetic unit.Arithmetic unit adds this clocking value
After one redundancy duration, result is issued into the predetermined time current as timer 1 of timer 1.
In simple terms, timer 2, comparator, arithmetic unit function be to obtain the jump of current input read-write indication signal
Period, and judge whether input signal is square wave using this period as benchmark.
As it can be seen that CPLD is according to the hop period of the level jump in the present embodiment when reading and writing indication signal and jumping
It determines the waiting time, that is, determines the signal intensity period.When read and write indication signal variation faster when, can use shorter
The signal intensity period judged, when read and write indication signal variation it is longer when, can using the longer signal intensity period into
Row judgement.The waiting time for becoming constant level again from flashing by shortening avoids the instruction information that transmitting makes mistake, and reduces hair
Raw a possibility that misreading.
