As the further scheme of the present invention: described flame detector and be wireless connections between heat detector and fire alarm main frame.
As the present invention's further scheme: be provided with PLC control system in described fire alarm main frame.
As the present invention's further scheme: the reference time delay of described electromagnetic actuator device is 0 ~ 30s.
As the present invention's further scheme: described main control system B controls fire-extinguishing apparatus, and described fire-extinguishing apparatus comprises dry-ice fire extinguisher, foam annihilator and sand fire extinguisher.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is reasonable in design, accurately can identify whether breaking out of fire, prevent the situation because maloperation or breakdown detector cause fire-extinguishing apparatus to spray by mistake, avoid because of the unexpected economic loss caused.When breaking out of fire, response rapidly, can put out various types of fire fast.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 2, a kind of CO
2gas fire automatic detection and control fire extinguishing system, comprise flame detector 1, heat detector 2, personal control 3, main control system A4, main control system B5, main control system C6, alarm bell 7, Electrically operated gate 8, exhaust blower 9, audible-visual annunciator 10, electromagnetic actuator device 11 and fire alarm main frame 12; Described flame detector 1, heat detector 2 are connected fire alarm main frame 12 with personal control 3 input; Fire alarm main frame 12 exports connection control host A 4, main control system B5, main control system C6, alarm bell 7, Electrically operated gate 8, exhaust blower 9, audible-visual annunciator 10 and electromagnetic actuator device 11.
Further, flame detector 1 of the present invention and be wireless connections between heat detector 2 and fire alarm main frame 12.
Further, PLC control system is provided with, working stability, fast response time, long service life, failure rate is low in fire alarm main frame 12 of the present invention.
Further, the reference time delay of electromagnetic actuator device 11 of the present invention is 0 ~ 30s.
Further, main control system B5 of the present invention controls fire-extinguishing apparatus, and described fire-extinguishing apparatus comprises dry-ice fire extinguisher, foam annihilator and sand fire extinguisher, can put out various types of fire fast.
The present invention is before fire extinguishing system release extinguishing chemical or simultaneously, can ensure necessary combined operation, namely fire extinguishing system is when sending fire extinguishing instruction, sends interlock instruction, cuts off the electricity supply, close or stop all affecting the equipment of extinguishing effect by control system.
Fire extinguishing device jet head spreads all over indoor four corners, can cover entire area, reach best extinguishing effect.
In the present invention, Fire extinguisher is furnished with explosion-proof type flame detector and explosion-proof type heat detector and temp. controlling alarm.In protection zone, be provided with flame detector 1, heat detector 2 and explosion proof type combustible gas detector, the gas-tight indicator lamp of the arranged outside in gateway, promptly open/stop button, audible-visual annunciator 10 and alarm bell 7.
When flame detector 1 and heat detector 2 send fire signal simultaneously, controller is judged as fire alarm, sends interlock instruction immediately; close the interlocking equipment such as fire resisting damper, blower fan; (as confirmed as fire alarm wrong report in delay time, the emergency stop push button at protection zone place can be pressed immediately, can start by termination system after the time delay of 10-30 second (adjustable); spray is by mistake avoided to cause the accident); namely send fire extinguishing instruction, open magnetic valve, drive container value; release extinguishing medium, implements fire extinguishing.
Native system signal adopts 2 bus systems, and detector strip is encoded, and each district signal is directly delivered in gas fire-fighting controller and processed.
In the design, be defined in each setting area, when any two detectors are reported a fire simultaneously, then system performs and spurts action.Protection zone, underground is the safe escape of guarantee personnel, before release extinguishing chemical, can send outfiring alarm, and the delay time extremely discharging extinguishing chemical of reporting to the police is 30S.
Time when special circumstances occur as controller, detector inefficacy, extract the safety pin of storage bottle group, bounce the hand push button (needed for this guard plot bottle group) in storage bottle group, this fire extinguishing system can be started, implement fire extinguishing.
System arranges sound outside protection zone, light is reported to the police and release signal mark, and overall monitoring is abnormal to be occurred.
This fire extinguishing monitoring detection system can automatically switch, automatic switchover gas, design for providing the requirement of uninterrupted air feed, by setting lower limit alarming value, when main air feed bottle group Pressure Drop is low to moderate setting pressure, system starts to switch, main air feed bottle group end is closed automatically, bailout bottle group end starts air feed, and personnel can change main air feed empty bottle group simultaneously, realizes uninterrupted for airway dysfunction.Operating limit pressure due to empty bottle is 0.980MPa, so the pressure switched is set to 0.8 ~ 1MPa, comparatively common fire setting is more reasonable.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
