In detail, staff can be continued with the maximum arranging the judgement cycle according to self-demand or based on experience value
Duration.For example, maximum duration can preferably be 10s, and that is, monitoring client needs monitoring within the 10s time limit, the first heart beating letter
Whether there is high level in number.
Based on the above, if monitoring client monitors there is high level in the first heartbeat signal, and monitor high level
Moment was located in the 10s time limit, therefore can illustrate that extending controller work at present is normal.Meanwhile, monitoring client once monitors high electricity
Flat presence, you can next time monitored immediately.Accordingly, if monitoring client, before reaching the 10s time limit, does not monitor all the time
There is high level in first heartbeat signal, therefore can illustrate that extending controller work at present is abnormal, therefore the 10s time limit can reached
When, control extending controller to be resetted to release exception immediately.
In an embodiment of the invention, in order to a kind of enabled side controlling extending controller to be resetted is described

Continuous duration can preferably be 100ms.Monitoring client persistently drags down enabling signal after 100ms, again can draw enabling signal
Height, so that extending controller is reworked.Certainly, in an embodiment of the invention, monitoring client persistently drags down enabling signal
After 100ms, enable signal and can also be automatically restored to high level.
When in detail, due to enabling signal for low level, extending controller quits work, therefore does not export first during this period
Heartbeat signal.When enable signal reverts to high level by low level, extending controller restarts normal work, therefore continues real
When export the first heartbeat signal.Accordingly, monitoring client, after controlling extending controller to be resetted, needs again input to be in real time somebody's turn to do
First heartbeat signal.
In an embodiment of the invention, in order to a kind of possible timing implementation is described, so, described determination judges
The maximum duration in cycle, comprising: determine the maximum duration in judgement cycle, and described maximum duration is corresponding to extremely
Few two count numbers；
Described from currently judging that the initial time in cycle proceeds by timing, comprising: from currently judge the cycle initial when
Proceed by constant duration sequential counting quarter, and the numeral starting counting up is the first number in described at least two count numbers
Word；

Described timing and continuous duration reaches described maximum duration, comprising: the numeral of current count is described last digit
Word.
As an example it is assumed that judging that the maximum duration in cycle is can be suitable with constant duration in 10s, and 10s time
Sequence counts 100 times.Therefore 10s can correspond to 100 count numbers, can be such as the 0～99 of positive sequence, wherein, the first numeral is
0, last figure is 99.It is of course also possible to be the 99～0 of inverted order.
In detail, when monitoring client execution arbitrarily once judges the cycle, when the initial time judging the cycle proceeds by etc.
Between intervening sequences count, such as can count 0 successively, 1,2,3,4 ..., 99.Wherein, this counting operation can be by monitoring client
The enumerator of internal setting completes.
Based on the above, within the current judgement cycle, when monitoring client monitors to exist height first in the first heartbeat signal
Level, and enumerator count numbers now are not 99, such as when 30 it may be said that bright extending controller is working properly, therefore permissible
Terminate the current judgement cycle and start the next judgement cycle.Certainly, when entering the next judgement cycle, the current meter of enumerator
Number numeral empties.
Accordingly, when enumerator starts counting up from 0, and when counting up to 99, if monitoring client does not monitor during this period all the time
There is high level in first heartbeat signal it may be said that bright extending controller operation irregularity, therefore extending controller can be controlled to carry out
Reset.
As shown in Fig. 2 the method embodiments providing another kind of monitoring extending controller, it is applied to extend control
Device, may comprise steps of:
Step 201: in real time according to the initial heart signal of itself, generate corresponding first heartbeat signal, and export described

Number, i.e. above-mentioned initial heart signal, this heartbeat signal regular is beated similar to the heart of the mankind.Accordingly, extension controls
During device abnormal work, the heartbeat signal that it exports in real time may be permanent for high level or permanent for low level.
Because monitoring client needs according to whether there is high level in heartbeat signal, with the indirect work determining extending controller
State, therefore when extending controller abnormal work and when exporting the permanent heartbeat signal for high level, monitoring client is based on this heartbeat signal,
The working condition of extending controller generally can not accurately be determined.Therefore, it can be processed initial heart signal, and will process
The first heartbeat signal obtaining afterwards exports to monitoring client.

Number, can be counted from left to right according to time sequencing, in such as Fig. 3 be counted as 1 successively, 2 ..., 10.heartbeat
(heart beating) signal can be above-mentioned initial heart signal.Heartbeat_delay (heart beating delay) signal can be above-mentioned second
Heartbeat signal.Heartbeat_n signal can be above-mentioned 3rd heartbeat signal.Plus (plus and) signal can be above-mentioned first
Heartbeat signal.
As shown in figure 3, heartbeat signal is carried out delay disposal, heartbeat_delay signal can be obtained, its
In, time delay is the half of a cycle of clock signal.Heartbeat signal is carried out negating process, can obtain
Heartbeat_n signal.Heartbeat_delay signal and heartbeat_n signal are carried out and process, can obtain
To plus signal.Plus signal can be exported in real time to monitoring client.In theory, the width of each high level of plus signal
It should be the half of a cycle of clock signal.
In detail, monitoring client can carry out constant duration sequential counting according to clock signal, and this time interval etc.
A cycle in clock signal.The time delay that extending controller execution delay disposal is based on is equal to the one of clock signal
The half in individual cycle.As shown in figure 3, when monitoring client counts up to digital 3 by numeral 1, the first heartbeat signal can be monitored, that is,
There is high level in plus signal in Fig. 3.Assume, countable 100 times in maximum duration, to illustrate to count up to when digital 3 not
Reach maximum duration, therefore current count numeral can be removed, terminate the current judgement cycle and start the next judgement cycle.
As shown in figure 4, one embodiment of the invention provide another monitoring extending controller method, specifically include with
Lower step:
Step 401: monitoring client predefines the maximum duration in judgement cycle, and maximum duration corresponds to 100
Individual count numbers.
For example, maximum duration can be 10s, and monitoring client can carry out 100 countings in 10s, such as can
To count up to 99 from 0 positive sequence, or 0 can be counted up to from 99 inverted orders.
Step 402: extending controller predefines the clock signal that dutycycle is 50%.
Step 403: extending controller determines the heartbeat signal of itself in real time.
In detail, heartbeat signal is the initial heart signal of extending controller.
Step 404: the hopping edge based on heartbeat signal for the extending controller, with the one of a cycle of clock signal
Half is time delay, and heartbeat signal is carried out delay disposal to obtain heartbeat_delay signal.
In detail, hopping edge can be to go to low level trailing edge from high level, or, going to high level from low level
Rising edge.
Step 405: heartbeat signal is carried out negating process to obtain heartbeat_n signal by extending controller.
In detail, heartbeat signal and heartbeat_n signal are contrary in the level height of synchronization.
Step 406: heartbeat_delay signal and heartbeat_n signal are carried out and place by extending controller
Reason is to obtain plus signal, and exports plus signal in real time to monitoring client.
In detail, heartbeat_delay signal and heartbeat_n signal be when synchronization is high level,
Plus signal is high level in this moment, and otherwise, plus signal is low level in this moment.
In detail, extending controller can be by the plus signal real-time Transmission being generated based on heartbeat signal to prison
Control end, so that monitoring client is according to this plus signal, judges that the working condition of extending controller whether there is abnormal indirectly.
Step 407: the plus signal of monitoring client input expanding controller output in real time.
Step 408: monitoring client is from currently judging that the initial time in cycle proceeds by constant duration sequential counting, and open
The numeral beginning to count is the first numeral in 100 count numbers, there is high level and currently count in judging plus signal
When the numeral of number is not the last figure in 100 count numbers, execution step 409, in the numeral judging current count be
Last figure and when not judging to there is high level in plus signal, execution step 410.
In detail, monitoring client equally can predefine the clock signal that above-mentioned dutycycle is 50%, and is based on clock
Signal carries out constant duration sequential counting.Wherein, this time interval can be equal to a cycle of clock signal.

Output duration when reaching respective settings threshold value, be set to high level by enabling signal, and execution step 407.
In detail, monitoring client passes through to control the level height enabling signal, to control extending controller to be resetted.
In detail, when to enable signal be low level, extending controller generally can not normal work, therefore can not export in real time
Plus signal is to monitoring client.When enable signal reverts to high level by low level, extending controller can continue normal work, therefore
Can continue to export plus signal in real time to monitoring client.Therefore, monitoring client, after controlling extending controller to be resetted, needs again
The plus signal of secondary input expanding controller output in real time.
Step 411: extending controller determine enable signal high level is reverted to by low level when, execution step 403.
Same as above, when enable signal reverts to high level by low level, extending controller continues normal work, therefore needs
Determine the heartbeat signal of itself again in real time, and execution follow-up based on heartbeat signal generation plus signal.
