The specific embodiment of above-mentioned technical proposal includes in the following manner：
Embodiment 1：Triode high level detection mode
As shown in Figure 1-Figure 3, if stator-device 2 is when exporting signal, sub- equipment 2 exports signal input part 312 low
Level, and sub- equipment 2 it is no output signal when, sub- equipment 2 to signal input part 312 export high level；Meanwhile operate
Detection power supply 4 make its to power end 311 to output high level；
When sub- equipment 2 is not over 312 input signal of signal input part, the base stage of triode Q1 is high level, therefore
Deflect, the high level of power end 311 will flow to the earth via the collector and emitter of triode Q1；Again since signal is defeated
Outlet 313 is connected with power end 311, therefore signal output part 313 similarly exports low level to main equipment 1；Main equipment 1 at this time
What is detected from detection chain 6 is low level；
And group equipment 2 by 312 input signal of signal input part when, the base stage for causing triode Q1 will be received low
Level so that triode Q1 does not deflect, so that signal output part 313 exports high level；
Again since the port set of several detection devices 3 is sequentially connected in series and is formed detection chain 6 for 321 32,
In some sub- equipment 2, an only sub- equipment 2 does not export signal, other sub- equipment 2 export signal, other sub- institutes of equipment 2
The high level that the signal output part 313 of the detection device 3 of connection is exported, will also pass through and do not export the sub- equipment 2 of signal and connect
The triode Q1 of the detection device 3 connect flows into the earth, therefore the high level that main equipment 1 still can not be detected from detection chain 6,
And then it will be unable to complete communication；
Therefore, having and only detecting the sub- equipment 2 that chain 6 is detected has signal output, detects the detection device 3 on chain 6
Triode Q1 just can not deflect so that the signal output part 313 of each detection device 3 all exports high level,
Therefore, when main equipment 1 can detect high level from detection chain 6, can complete to communicate.
Therefore, the logic of high level detection mode is only to be connected on detection chain 6 all sub- equipment 2 while all defeated
Signal is gone out, the communication to main equipment 1 can be completed.
Embodiment 2：Triode low level detection mode
As shown in Figure 1-Figure 3, if stator-device 2 is when exporting signal, sub- equipment 2 exports height to signal input part 312
Level, and sub- equipment 2 it is no output signal when, sub- equipment 2 to signal input part 312 export low level；Meanwhile operate
Detection power supply 4 make its to power end 311 to output high level；
When sub- equipment 2 is not over 312 input signal of signal input part, the base stage of triode Q1 is low level, therefore
Do not deflect, so that signal output part 313 exports high level；The electricity detected in chain 6 is detected of main equipment 1 at this time
Put down as high level；
And group equipment 2 by 312 input signal of signal input part when, the base stage for causing triode Q1 will be received into height
Level so that triode Q1 deflects, and the high level of power end 311 will be flowed to via the collector and emitter of triode Q1
Greatly；Again since signal output part 313 is connected with power end 311, signal output part 313 is similarly exported to main equipment 1
Low level；
Again since the port set of several detection devices 3 is sequentially connected in series and is formed detection chain 6 for 321 32,
In some sub- equipment 2, an only sub- equipment 2 outputs signal, and when other sub- equipment 2 do not export signal, other sons are set
The high level that the signal output part 313 of standby 2 detection devices 3 connected is exported, will also pass through the sub- equipment 2 for having exported signal
The triode Q1 of the detection device 3 connected flows into the earth, therefore the low level that main equipment 1 will be detected from detection chain 6, into
And realize communication.Therefore, the logic of low level detection is in some sub- equipment 2 connected on detection chain 6, as long as there is 1
Or more sub- equipment 2 output signal, can realize the communication to main equipment 1.
Embodiment 3：Relay switch high level detection mode
As shown in Figure 1, Figure 4 and Figure 5, if stator-device 2 is when exporting signal, sub- equipment 2 is defeated to signal input part 312
Go out low level, and sub- equipment 2 is when no output signal, sub- equipment 2 exports high level to signal input part 312；Meanwhile
Operation detection power supply 4 make its to power end 311 to output high level；
When sub- equipment 2 is not over 312 input signal of signal input part, the coil lead of relay switch K1 is high electricity
Flat, hence in so that two normally opened contacts contact of relay switch K1, the high level of power end 311 will be via relay switch K1
Flow to the earth；Again since signal output part 313 is connected with power end 311, signal output part 313 to main equipment 1 similarly
Export low level；What main equipment 1 was detected from detection chain 6 at this time is low level；
And group equipment 2 by 312 input signal of signal input part when, will cause relay switch K1 coil lead will
Receive low level so that two normally opened contacts of relay switch K1 are not enough to be in contact, so that signal output part
313 output high level；
Again since the port set of several detection devices 3 is sequentially connected in series and is formed detection chain 6 for 321 32,
In some sub- equipment 2, an only sub- equipment 2 does not export signal, other sub- equipment 2 export signal, other sub- institutes of equipment 2
The high level that the signal output part 313 of the detection device 3 of connection is exported, will also pass through and do not export the sub- equipment 2 of signal and connect
The relay switch K1 of the detection device 3 connect flows into the earth, therefore the height that main equipment 1 still can not be detected from detection chain 6
Level, and then will be unable to complete communication；
Therefore, having and only detecting the sub- equipment 2 that chain 6 is detected has signal output, detects the detection device 3 on chain 6
Two normally opened contacts of relay switch K1 be not in contact so that the signal output part 313 of each detection device 3
High level is all exported, therefore, when main equipment 1 can detect high level from detection chain 6, can complete to communicate.
Therefore, the logic of high level detection mode is only to be connected on detection chain 6 all sub- equipment 2 while all defeated
Signal is gone out, the communication to main equipment 1 can be completed.
Embodiment 4：Relay switch low level detection mode
As shown in Figure 1, Figure 4 and Figure 5, if stator-device 2 is when exporting signal, sub- equipment 2 is defeated to signal input part 312
Go out high level, and sub- equipment 2 is when no output signal, sub- equipment 2 exports low level to signal input part 312；Meanwhile
Operation detection power supply 4 make its to power end 311 to output high level；
When sub- equipment 2 is not over 312 input signal of signal input part, the coil lead of relay switch K1 is low electricity
It is flat, therefore do not deflect, so that signal output part 313 exports high level；Main equipment 1 is examined in chain 6 is detected at this time
The level measured is high level；
And group equipment 2 by 312 input signal of signal input part when, will cause relay switch K1 coil lead will
Receive high level so that two normally opened contacts of relay switch K1 produce contact, the high level of power end 311 will via after
Electric switch K1 flows to the earth；Again since signal output part 313 is connected with power end 311, signal output part 313 is set to master
Standby 1 similarly exports low level；
Again since the port set of several detection devices 3 is sequentially connected in series and is formed detection chain 6 for 321 32,
In some sub- equipment 2, an only sub- equipment 2 outputs signal, and when other sub- equipment 2 do not export signal, other sons are set
The high level that the signal output part 313 of standby 2 detection devices 3 connected is exported, will also pass through the sub- equipment 2 for having exported signal
The relay switch K1 of the detection device 3 connected flows into the earth, therefore the low electricity that main equipment 1 will be detected from detection chain 6
It is flat, and then realize communication.Therefore, the logic of low level detection is, in some sub- equipment 2 connected on detection chain 6, as long as
The sub- equipment 2 for having 1 or more outputs signal, can realize the communication to main equipment 1.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
