Ying Tu, three-scale redundancy control system shown in Fig. 2 needs to realize by 0 to 1 jump process, the original state in three channels at this time
It is 0, the variation of the input signal of system occurs after certain sampling, in first control period, since sampling occurs
Before input signal variation, so three channels synchronize sampling, sampled value is 0, passes through the input number after input voting
According to being 0, the result by carrying out output voting after processing routine is 0.In second control period, the sampled value in three channels
It is 1, but when carrying out input voting, sampled value that each channel reception to other two channels transmits is that a upper control is all
The data that phase, i.e., the sampled value in first control period, therefore each channel participate in input voting are 1,0,0, due to taking
The mode of two from three is put to the vote, therefore the result for inputting voting is 0, and when carrying out output voting, each channel reception is arrived
The processing result of the processing routine in first control period of other two channels transmission is 0, so that second control period
Output voting result be also 0.Third controlled in the period, and the sampled value in three channels is 1, when carrying out input voting,
Each channel reception was a upper control period to the sampled value that other two channels are transmitted, i.e., second controls the sampling in period
Value, therefore it is 1,1,1 that each channel, which participates in the data of input voting, the result of the input voting in each channel is 1, but into
When row output voting, the processing result at processing routine that each channel reception is transmitted to other two channels is second control
The processing result of the processing routine in period, thus each channel participate in input voting data be 1,0,0, each channel it is defeated
The result decided by vote out is 0.In 4th control period, the sampled value in three channels is 1, each channel reception to other two
The sampled value that a channel is transmitted was a upper control period, i.e., the sampled value in third control period, each channel participate in input
The data of voting are 1,1,1, and the result of the input voting in each channel is 1, when carrying out output voting, each channel reception
The processing result of the processing routine transmitted to other two channels is the processing result for the processing routine that third controls the period, because
The data that this each channel participates in input voting are 1,1,1, and the result of the output voting in each channel is 1, at this time system
Output signal just complete by 0 to 1 transition response, the above-mentioned response process used time is four control periods.

It should be noted that after first preset time and second preset time confirm, above-mentioned S302 with
The sequence of S303 can be adjusted according to actual needs, such as at the beginning of the control period that can first adjust the third channel
Between lag the first passage the control period at the beginning of the sum of the first preset time and the second preset time, then adjust institute
At the beginning of the control period for lagging the first passage at the beginning of the control period for stating second channel first it is default when
Between.
The application is not especially limited the value of first preset time and second preset time, below with institute
It states the first preset time and second preset time is to illustrate herein described side for 1/3 control period
The principle of method:
For three-scale redundancy control system, each channel carries out data sampling at the beginning of controlling the period, considers
Variation to input signal can occur occur before the sampling in control period after the sampling in control period,
Illustrated respectively to both of these case below.
Illustrate that this method is used in specific workflow when sampling occurs before input signal variation first.
Referring to fig. 4, which is a kind of response diagram for three-scale redundancy control system that the embodiment of the present application one provides, by scheming
4 it is found that the first passage before the control period of the second channel starts occurs for the variation of the system input signal
The output voting that the period is controlled at first is 0, when the second channel starts to carry out input voting, the first passage
Sampled value has been transferred to the second channel, carries out input table since control period of the third channel at this time does not have started
Certainly, so the second channel is carrying out receiving the data of other two channels transmission when input voting being 0, thus it is described
The input voting result of second channel is 0, when the third channel starts to carry out input voting, the first passage and described
The sampled value of second channel has been transferred to the third channel, therefore the input voting result of the third channel is 1.
After the first passage enters second control period, itself collection value is 1, carry out when input is decided by vote described in second
Channel is 1 still in the collection value for other two channels transmission that in first control period, the first passage is received,
Therefore it is 1 that the first passage, which controls the input voting result in period at second,.Then the second channel carries out first
The output voting in period is controlled, the processing result of itself processing routine is 0, receives first control of the first passage transmission
The processing result of processing routine is 0 in period processed, since the processing routine of the third channel at this time does not complete also to input table
Processing certainly, the processing result that the second channel receives the processing routine of the third channel transmission is also 0, so described
The output voting result in second channel first control period is 0.Enter second control period to the second channel, itself
Collection value is 1, and the collection value that the second channel carries out the other two channels transmission received when input voting is also 1,
Therefore it is 1 that the second channel, which controls the input voting result in period at second,.At this point, the third channel is still in first
A control period, the third channel carry out the processing knot that the processing routine of other two channels transmission is received when output voting
Fruit is 0, and the processing result of itself processing routine is 1, therefore the output voting result of the third channel is 0.Institute at this time
The output voting that first passage carries out second control period is stated, the processing result of processing routine itself is 1, receives described the
The processing result of the processing routine of two channels transmission is 0, receives the processing result of the processing routine of the third channel transmission
It is 1, is put to the vote by the way of two from three due to being taken when output voting, so the first passage is second control week
The output voting result of phase is 1.When the second channel carries out the output voting in second control period, processing routine itself
Processing result is 1, and the processing result for receiving the processing routine of the first passage and third channel transmission is 1, because
The output voting result that this described second channel controls the period at second is 1.The first passage and described second leads at this time
The output voting result in road is 1, since the output signal of system is also put to the vote by the way of two from three, the output of system
The result of signal has determined as 1, and the three-scale redundancy control system completes the jump process of response at this time, and jumps
The used time of journey is the sum of 2 control periods and described 1 first preset time, i.e. 7/3 control period.
It continues with and illustrates that this method is used in specific workflow of sampling generation when after input signal variation.
Referring to Fig. 5, which is the response diagram for another three-scale redundancy control system that the embodiment of the present application one provides, by
Fig. 5 by above-mentioned adjustment it is found that operated, and in first control period, when the first passage carries out input voting, itself is adopted
Sample value is 0, but the second channel and third channel do not enter first control period also, therefore the first passage is first
The input voting result in a control period is 0.The subsequent second channel enters first control period, and the second channel is certainly
The sampled value of body is 1, and the sampled value for receiving first passage transmission is 1, due to the third channel at this time still not into
Enter first control period, so the sampled value of third channel transmission is 0, the second channel is first control period
Input voting result be 1.The subsequent third channel enters first control period, itself sampled value is 1, receives other
The sampled value of two channels transmission is 1, therefore it is 1 that the third channel, which controls the input voting result in period at first,.
The first passage is carried out in first output controlled in the period voting, and the processing result of the processing routine of itself is 0, is connect
The processing result for receiving the processing routine of other two channels transmission is also 0, therefore the first passage is controlled at first
Output voting result in period is 0.
The subsequent first passage enters second control period, carries out the input voting in second control period, from
Body collection value is 1, and the collection value for receiving other two channels transmission is also 1, therefore the first passage is controlled at second
The input voting result in period processed is 1.The second channel carries out the output voting in first control period, itself processing at this time
The processing result of program is 1, receives the processing result of the processing routine in first control period of the first passage transmission
It is 0, since the third channel does not complete the processing to input voting also at this time, so the processing journey of third channel transmission
The processing result of sequence is 0, therefore it is 0 that the second channel, which controls the output voting result in period at first, then described the
Two channels enter second control period, when the second channel carries out the input voting in second control period, itself sampling
Value is 1, and the sampled value for receiving other two channels transmission is also 1, therefore the second channel controls the period at second
Inputting voting result is 1.The third channel carries out the output voting in first control period, the place of itself processing routine at this time
Managing result is 1, and the processing result for receiving the processing routine that the period is controlled at first of the first passage transmission is 0, is connect
The processing result for receiving the processing routine that the period is controlled at first of the second channel transmission is 1, therefore the third is logical
The output voting result that road controls the period at first is 1.The first passage carries out the output in second control period at this time
Voting, the processing result of itself processing routine are 1, receive first control of the first passage and second channel transmission
The processing result of processing routine is 1 in period processed, therefore the first passage controls the output in period at second and decides by vote knot
Fruit is 1.Since the output voting result of the first passage and the third channel is 1 at this time, the output signal of system is adopted
Put to the vote with the mode of two from three, then the result of the output signal of system has determined as 1, at this time the three-scale redundancy control
System processed completes the jump process of response, and the used time for jumping process is 2 control periods.
For above description only by taking system input signal variation is by 0 to 1 as an example, the application is defeated to system input signal and system
The variation for entering signal is not especially limited.
It should be noted that above-mentioned analytic explanation is just for equal in first preset time and second preset time
The case where when for 1/3 control period, when the value of first preset time and second preset time changes
Above-mentioned workflow can also correspond to variation, and then influence system and complete the use for jumping to the response process of output jump from input
When.In addition, first preset time and second preset time can be the same or different, the application does not make this to have
Body limits, and under another possible embodiment, keeps first preset time identical with second preset time, such energy
Enough settings simplified while the response for the system that effectively shortens is time-consuming for the three-scale redundancy control system operate.
The fast response method for the redundancy control system that the embodiment of the present application provides is applied to three-scale redundancy control system
System, the three-scale redundancy control system include first passage, second channel and third channel, the first passage, described the
Two channels and third channel control period having the same, which comprises the control week of the first passage is set
At the beginning of phase；The control period of the first passage is lagged at the beginning of the control period for adjusting the second channel
The first preset time of time started；First preset time is less than the control period；Adjust the control of the third channel
Second preset time at the beginning of the control period for lagging the second channel at the beginning of period；It is described second it is default when
Between be less than the control period, by above-mentioned adjustment, by asynchronization at the beginning of the control period in three channels, in turn
So that three channels control the period in sampling time asynchronization, this make each channel carry out input voting and it is defeated
When deciding by vote out, the used time for obtaining the corresponding input data in other two channels and output data shortens, i.e., is grasped by above-mentioned adjustment
Make to reduce and complete control number of cycles needed for the mutual informing of data between triple channel, three-scale redundancy can be effectively improved
The response speed of control system.
Embodiment two:
The embodiment of the present application two additionally provides the fast response method of another redundancy control system, has with reference to the accompanying drawing
Body explanation.
Referring to Fig. 6, which is the fast response method for another redundancy control system that the embodiment of the present application two provides

It the described method comprises the following steps:
S601: at the beginning of the control period that the first passage is set.
Due to consideration that at the beginning of the adjustment control period caused by three-scale redundancy control system overall stability
It influences, can be set for the three-scale redundancy control system the unified predetermined system time, by the control in three channels
It is synchronized at the beginning of period.
It is can choose at the beginning of the control period of the first passage as the predetermined system time, it can also be again
Setting, the application is not especially limited this, and in a kind of mode in the cards, the control period of the first passage is opened

Further, in a kind of mode in the cards, the default adjustment amplitude and the predetermined deviation threshold value phase
Deng.It is illustrated for the deviation at the beginning of the control period for adjusting first passage below:
The control period is set as Tc, the deviation at the beginning of the control period of the first passage is β, described pre-
If the amplitude of adjustment and the predetermined deviation threshold value are ts, then the deviation at the beginning of the control period of the first passage can
Following three situation can be will appear:
Situation 1: if 0≤β < tsOr (Tc-ts)≤β, the deviation at the beginning of the control period of the first passage at this time
In tolerance, do not need to be adjusted.
Situation 2: if ts< β < (Tc/2) lags behind setting at the beginning of the control period of the first passage at this time
Time, adjustment mode are to shorten the current control period, and the adjustment amplitude shortened when adjustment every time is ts, do so can make it is next
A control period shifts to an earlier date tsStart.If next control Period Start Time still lags behind the time of setting, then after primary adjustment
Continue adjustment and shorten the current control period, the deviation at the beginning of the control period of the first passage returns to tolerance
In range.
Situation 3: if (Tc/2)≤β < Tc-ts, it is ahead of at the beginning of the control period of the first passage at this time and sets
Fixed time, adjustment mode are to extend the current control period, and extended adjustment amplitude is t when adjustment every times, doing so can make
Next control period postpones tsStart.If after primary adjustment, next control Period Start Time be still ahead of setting when
Between, then continue adjustment and extend the current control period, the deviation at the beginning of the control period of the first passage is returned
Into tolerance.
The beginning in the control period of deviation and adjustment third channel at the beginning of the control period for adjusting second channel
