In the present invention, the front end of the first transmitting-receiving code part 32 is triode 5 321, photo-coupler 3 322, triode six
323, the upper electrical switch that electronic switch 1 is constituted, realizes whether carry out signaling whether by powering on, that is, determines to be the first receipts
32 signaling of signaling part or the second transmitting-receiving 42 signaling of code part, one of control as main system to bus of the two continue
Signaling, another carries out auxiliary monitoring as from system control, to realize mutually harmonious cooperation and not influence mutually superfluous
Remaining control, and receiving and dispatching code is worked by the matrix wave of two kinds of level of 12V and 24V formation, can not only be carried out
The power supply of operating voltage can be realized communication, therefore entire communication system can be simplified, to improve working efficiency, reduce
The probability of device fails.
The present invention still is able to continue to keep normal operating conditions, the first master control after bus broken circuit, a master control failure
Both 3 and the second master control 4 are hot standby each other while dividing principal and subordinate to work again, and the two shows that content is consistent, redundancy smoke detector 1
It is connected in parallel in bus 2, after powering on, main master control control detection bus 2 carries out signaling, receipts code is carried out from master control detection bus signals,
When bus broken circuit, data are not received from master control, the first master control 3 and the second master control 4 just work at the same time, and control breaking position respectively
The detector for setting the right and left works；After a control system failure, another total stool control mode carries out work as main master control
Make；On the other hand, even if the detector mounted in bus 2 damages, because it is redundancy smoke detector 1, the first sense cigarette
Part 15 or the second sense cigarette part 16, damage cannot influence its normal work, thus detector position point may be implemented
Redundancy and entire control system and bus comprehensive redundancy, multi-level redundancy so as to preferably cope with it is various complexity
Detect operating condition.
In the present invention, redundancy smoke detector 1 can also be connected in bus 2, can be realized in bus short circuit in this way
When, it still is able to be worked normally, to improve the redundancy level of system.
In the present invention, transmitting-receiving code part can be completed by two buses, 24V signaling circuit 325 and 12V signaling circuit
326, which cooperate, carries out signaling, and advanced coding, decoding technique and software filtering technology can effectively inhibit external interference
Signal, so that the first master control 3 and the second master control 4 be enable to reach perfect cooperation and high dependable with function.
