One controller and second controller control the first sense cigarette part and the second sense cigarette part respectively, and first controls
Data communication can be carried out by photo-coupler one and photo-coupler two between device, second controller thus realize
Multiple-working mode, can the first sense cigarette part and the second sense cigarette part work simultaneously, but point principal and subordinate, wherein
One keeps operation detection to go out concrete on fire, and another is confirmed, both meet condition side simultaneously and assert fire,
Thus reduce wrong report；Can also both separated in time alternations, one of them can standby have a rest,
Thus well keep the first sense cigarette part and the accuracy of detection of the second sense cigarette part, extend both make simultaneously
Use the life-span；Or first two mode combines, the first sense cigarette part and the second sense cigarette part divide principal and subordinate, Er Qiejin
Row is alternately；After in the first sense cigarette part and the second sense cigarette part, one of them breaks down, another one is just made
It is main sense cigarette part, is persistently operated, therefore by the redundancy between the first controller and second controller
Mating reaction, just can under a plurality of modes of operation, by the first sense cigarette part in smoke detector and the second sense
Detection and the continuous firing of cigarette part well combine, such that it is able to for meeting various complex working condition
It is delayed detection demand, about one times will be extended service life simultaneously, any fire alarm can be met on-the-spot, special
It not to meet to require extremely harsh operating mode in nuclear power station station, on this basis, the most well achieve wrong report
Eliminating, equipment damage rate, the reduction of fault rate, and the growth that accuracy of detection is over time also can't
There is significantly reduction.
2, in the present invention, the first transmitting tube, the first reception pipe, the second transmitting tube, the second reception pipe are cross
Arranging and be inclined in labyrinth, in four passages being i.e. arranged on labyrinth, channel inner surface is smooth
Face, can more preferable transmission ray, the first transmitting tube, the first focus receiving pipe extended line are first sensitive
District, the second transmitting tube and the second focus receiving pipe extended line are the second sensitive volume, the first sensitive volume and second
Sensitive volume is overlapping or partly overlaps, it is possible to achieve preferably smoke detection effect.
3, in the present invention, automatic encoding part can carry out address successively to the first controller and second controller
Coding, i.e. encodes respectively to the first sense cigarette part and the second sense cigarette part, and the first coding circuit is to first
Sense cigarette part carries out automatic encoding, and the second coding circuit carries out automatic encoding to the second sense cigarette part, after coding,
Redundancy detector can be facilitated to carry out detecting control and malfunction coefficient by the control system that bus correspondence connects,
Realize the most remotely managing.
4, in the present invention, bus short circuit detection part can detect that two-wire system data are held concurrently the total of power line in real time
Line is whether to be short-circuited, if being short-circuited, will feedback control system carry out the control of other mode from
And still keep normal duty, thus realize more preferable fault adaptability, improve serious forgiveness.
5, in the present invention, outside the first sense cigarette part and the second sense cigarette Partial coordination work, also with the first temperature-sensitive electricity
Resistance and the second critesistor coordinate work, can preferably be realized respectively with temperature-sensitive dual redundant by sense cigarette
Plant mode of operation, thus improve detection accuracy and service life further, reduce rate of false alarm and fault further
Rate.

Instruction equipment working state.
7, in the present invention, first transmitting-receiving code part front end be audion five, photo-coupler three, audion six,
The upper electrical switch that electrical switch one is constituted, realizes whether carrying out signaling by whether powering on, and i.e. determines it is the
One transmitting-receiving code part signaling, or the second transmitting-receiving code part signaling, both one of them as main system control
Continuing signaling to bus, another one controls to carry out auxiliary monitoring as from system, thus realizes the most harmonious
The Redundant Control coordinated and do not affect mutually, and receive and dispatch code and formed by two kinds of level of 12V and 24V
Matrix ripple is operated, and can not only be operated the power supply of voltage, it is possible to realize communication, therefore may be used
To be simplified by whole communication system, thus improve work efficiency, reduce the probability of device fails.
8, the present invention is after bus broken circuit, a master control fault, remains able to continue to keep normal operating conditions,
First master control and the second master control divide again principal and subordinate to be operated the while of the most hot standby, and both show that content is consistent,
Redundancy smoke detector is connected in parallel in bus, and after powering on, main master control controls detection bus and carries out signaling, from always
Control detection bus signals carry out receive code, when bus broken circuit, do not receive data from master control, the first master control and
Second total stool control mode works simultaneously, and the detector controlling off position the right and left respectively is operated；When one
After control system fault, another total stool control mode is operated as main master control；On the other hand, even if in bus
The detector of mounting damages, because it is redundancy smoke detector, and the first sense cigarette part or the second sense cigarette
Part, infringement all can not affect it and normally works, thus can realize detector position point redundancy and
Whole control system and comprehensive redundancy of bus, multi-level redundancy is such that it is able to preferably tackle various complexity
Detection operating mode.
9, in the present invention, redundancy smoke detector can also be connected in bus, the most just can be implemented in total
During line short circuit, remain able to normally work, thus improve the redundancy level of system.
10, in the present invention, transmitting-receiving code part just can be completed by two buses, 12V signaling circuit and 24V
Signaling circuit cooperates and carries out signaling, advanced coding, decoding technique and software filtering technology, it is possible to have
The suppression external interference signal of effect, so that the first master control and the second master control can reach perfectly to coordinate, with
And high dependable with function.
