Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawing and specific implementation
The present invention is described in detail for example.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
The change of current as shown in Figure 1 and Figure 2 becomes fire-fighting and monitors system, mainly includes that the change of current becomes fixed fire-fighting system, fire alarm
Controller, HMI, the change of current become exchange side breaker, heat detector 2 and flame detector 5, the heat detector 2 with change
Rheology ontology connects and exports temperature signal to fire alarm control unit, and the flame detector 5 is for detecting change of current change
The flare up fire of sending simultaneously exports flare up fire to fire alarm control unit, and the fire alarm control unit, the change of current, which become, hands over
Stream side breaker becomes fixed fire-fighting system formation with the change of current respectively and is electrically connected, shape between the HMI and fire alarm control unit
At electrical connection.
When becoming fire-fighting monitoring system exchange rheology progress fire-fighting monitoring using the above-mentioned change of current, in order to guarantee and improve the change of current
Become the faulty action preventing reliability of fire-fighting system, heat detector 2 therein is arranged 2 sets, and the heat detector 2 preferably uses line
Heat detector 2 can be become the winding laying of cabinet 1 along the change of current by type heat detector, can also be by heat detector 2 along valve side
The winding laying of bushing lifting seat 3, the value side bushing increase seat 3 and are fixedly connected with value side bushing 4；It can also be by heat detection
Conservator 7 of the device 2 in change of current change winds laying, heat detector 2 can also be increased the winding laying of seat 8, institute along network side sleeve
The network side sleeve stated increases seat 8 and is fixedly connected with network side sleeve 6.
In general, being that heat detector 2 is successively become cabinet 1, value side bushing raising seat 3, network side sleeve along the change of current to increase
Seat 8, conservator 7 progress sequence winding laying.When carrying out the winding operation of heat detector 2,2 sets of heat detectors 2
Canoe it is identical, and 2 sets of 2 apart windings of heat detector." apart windings " at this refer to wherein a set of heat detection
A circle of another set of heat detector 2 is embedded between the two adjacent rings of device 2.The flame detector 5 preferably uses image
Type flame detector and setting at least one.In general, 3, and 3 equal rings of flame detector 5 are arranged in the flame detector 5
The change of current becomes setting, exchanges rheology progress Multi-orientation multi-angle monitoring will pass through flame detector 5.Therefore, every change of current becomes peace
2 sets of heat detector 2 and 1 set flame detectors (3 flame detectors 5) is filled, totally 3 sets of fire detecting arrangements.
As shown in figure 3, the above-mentioned change of current becomes fire-fighting monitoring system at work, include the following steps:
Firstly, by heat detector 2 to fire alarm control unit output temperature signal, by flame detector 5 to fire
Calamity alarm controller exports flare up fire, becomes exchange side breaker by the change of current and exports quartile letter to the fixed fire-fighting system of change of current change
Number.Usually there are 2 since change of current change exchanges side breaker, is denoted as change of current change exchange side breaker 1 respectively, change of current change exchanges side and breaks
Road device 2, therefore, becoming exchange side breaker from the change of current has 2 tunnels to the quartile signal that the change of current becomes fixed fire-fighting system output.
Then, two from three logic fortune is carried out to the temperature signal and flare up fire received by fire alarm control unit
It calculates, then fixed fire-fighting system is become by the change of current, logic and operation is carried out to two from three logical signal and quartile signal.
Finally, when the change of current becomes fixed fire-fighting system judgement two from three logical signal and quartile signal meets simultaneously, at this point,
The change of current, which becomes exchange side breaker, becomes the change of current in off-position, that is, the change of current become the fixed fire-fighting system confirmation change of current become without
Electricity." two from three logical signal satisfaction " at this refers to, when fire alarm control unit determines appointing in 3 sets of fire detecting arrangements
When the temperature signal and/or flare up fire that two sets of fire detecting arrangements of meaning are issued reach setting alarm criteria, fire alarm control
Device processed issues fire alarm signal, at this point, being regarded as change of current change has occurred fire, therefore, the change of current becomes fixed fire-fighting system
System starts at once, to stamp out a fire in time, prevents fire behavior from spreading, and reduces fire damage.When fire alarm control unit determines 3 sets
The temperature signal or flare up fire that only 1 set of fire detecting arrangement is issued in fire detecting arrangement reach setting alarm criteria
When, that is, it is considered fire false positive signal, does not will start at this point, the change of current becomes fixed fire-fighting system, changed so as to effectively improve
The faulty action preventing reliability of rheology fire-fighting system.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention should be included in guarantor of the invention
Within the scope of shield.
