Step 2；When the two remaining amount of enumerating signals are all effective, carry out step 3；When the single remaining amount of enumerating signal is effective, walked
Rapid four；
Step 2, judge whether the triplex redundance amount of enumerating state is consistent；When the triplex redundance amount of enumerating state is all consistent, walked
Rapid 2.1；When the two remaining amount of enumerating state consistencies, another passage is inconsistent, carries out step 2.2；When the triplex redundance amount of enumerating state two
Two is all inconsistent, carries out step 2.3；
The state value of the consistent described triplex redundance amount of the enumerating state of step 2.1, output is as the vote value of the amount of enumerating signal；
Step 2.2, put the amount of the enumerating signal fault of inconsistent passage, export the consistent described two remaining amount of enumerating states
State value is as the vote value of the amount of enumerating signal
Step 2.3, put the equal fault of the amount of enumerating signal of three passages, and export failure safe value；
Step 3, judge that the two remaining amount of enumerating states are whether consistent, when consistent, carry out step 3.1；Otherwise, carry out step
3.2；
The state value of the consistent described two remaining amount of the enumerating states of step 3.1, output is as the vote value of the amount of enumerating signal
Step 3.2, put the equal fault of the amount of enumerating signal of two passages, and export failure safe value；
Step 4, export the described single remaining amount of enumerating state state value as the amount of enumerating signal vote value.
Invention effect：
The triplex redundance amount of the enumerating monitoring means of voting of the present invention, by being compared to the state of the amount of enumerating signal, adopts
The result of majority signal is as vote value, and determines the malfunction of signal by the principle of majority voting, realizes fault is carried out
Monitor, isolate and declare；One aspect of the present invention solves the voting of conventional discrete amount and policing algorithm cannot be realized more than the amount of enumerating
The problem of degree management；In addition, this algorithm also is adapted for voting and the monitoring of conventional discrete amount simultaneously；Further, traditional discrete magnitude
Voting and algorithm need to be compared after each channel signal is sued for peace again, and this algorithm directly passes through simply to compare realization, calculates
Method is simply easily achieved.
