Description
Technical field
The present invention relates to fire extinguishing system control fields, and in particular to a kind of control method of automatic gas fire extinguishing system.
Background technology
With the quickening of Urbanization Process In China, various houses, megastore, public place of entertainment and public gathering etc. personnel
Intensive place is gradually increased, and skyscraper, complex building are also more and more common, once fire has occurred, is easily caused a large amount of
Casualties.According to official of Fire-Fighting Bureau under the Ministry of Public Security wechat public platform message, 2016, national fire 31.2 ten thousand of being informed of a case altogether was died
1582 people hinder 1065 people, and 37.2 hundred million yuan of direct property loss, compared with 2015, four item of digital have decline.Wherein, larger
Fire 64 rises, and reduces 4 on year-on-year basis, declines 5.9%；Do not occur great and special fire disaster, it is complete for the first time since founding of New
The fire of primary dead 10 people or more does not occur year.It was verified that establishing effective extinguishing device, fire is in the embryonic stage
When implement fire-fighting protection, be the effective way that less fire occurs.Especially develop intelligentized automatic fire extinguishing system, Neng Gou great
The big loss for reducing casualties and property caused by fire occurs.
Automatic fire extinguishing system mainly has two major classes：Automatic above-water method and automatic gas fire extinguishing.Extinction using gas cost is relatively low,
Most basic extinguishing device, but it is larger to fire-extinguishing location destructiveness, and extinction using gas efficiency is relatively high, to scene of fire destructiveness
It is small, therefore it is widely available application.Extinction using gas has Fire-extinguishing System of Septenary-Fluorine Propane, mixed gas fire extinguishing system, carbon-dioxide fire engine
System etc. constantly rises in the temperature of fire early period of origination, building or smokescope rising forces respectively to a certain extent therewith
The different primary element of kind changes and then fire extinguishing system is made to operate automatically, starts to put out a fire.When temperature equivalence returns to normal it
Afterwards, system is just automatically stopped.
It is the general control method of general automatic gas fire extinguishing system above, but traditional extinguishment control system controlling party
Fado is there are not smart enough, the disadvantages such as reliability is low, and the present invention provides a kind of intelligentized extinguishment control system controlling parties
Method improves system reliability and reduces cost.
Invention content
The present invention includes a kind of control method of extinguishment control system, and the extinguishment control system includes sensor unit,
Control unit, gas integrated control valve carry out gas tank, gas line network tank, the net pressure monitor system of pressure detecting, distally disappear
The compositions such as anti-control centre, the extinguishment control system include that described control unit passes through the spies such as temperature, flue gas by sensing unit
Survey mode detects the fiery parameter of combustion, and notice control unit starts fire extinguishing program after the fiery parameter of the combustion is more than given threshold, no
Continuation locator is then returned, exports enabling signal to gas integrated control valve first, starts gas extinguishing system operation, operation
While carry out tank, net pressure monitoring and gas extinguishing system continued to run with, when tank, net when tank, net pressure region setting value
Pressure cuts off gas integrated control valve when being higher than setting value, stops the conveying of fire-suppressant gas；
While described control unit controls hair output enabling signal to gas integrated, electricity is exported to gas integrated control valve
Signal is alarmed to fire protection control center by the electric signal, judges tank, net pressure according to the measurement result of tank, net pressure monitoring
If being higher than setting value, gas integrated control valve is cut off, the conveying of fire-suppressant gas is stopped；
Whether the measurement result according to tank, net pressure monitoring is higher than the judgement of setting value by controlling to tank, net pressure
Unit or fire protection control center judge that the two all has permission cut-out gas integrated control valve, stops the conveying of fire-suppressant gas.
Preferably, the control method of the extinguishment control system, wherein described control unit are to gas integrated control valve
Electric signal is exported, is alarmed to fire protection control center by the electric signal, adoptable is 38 volts of wire transmission and by UPS standby electricities
Source powers, wherein the electric signal is amplified by signal amplifier.
Preferably, described control unit exports electric signal to gas integrated control valve, alarms, can adopt to fire protection control center
It is transmission of wireless signals mode.
Preferably, wifi signals can be used in the wireless signal transmission.
Preferably, 4G or 5G signals can be used in the wireless signal transmission.
Preferably, whether the measurement result according to tank, net pressure monitoring is higher than tank, net pressure the judgement of setting value
Being judged by control unit or fire protection control center, the two all has permission cut-out gas integrated control valve, stops fire-suppressant gas conveying,
The permission priority of described control unit is higher than fire protection control center.
Further alternative, whether the measurement result according to tank, net pressure monitoring is higher than setting value to tank, net pressure
Judgement judge that the two all has permission cut-out gas integrated control valve, stops fire smothering gas by control unit or fire protection control center
Body conveys, and the priority of the fire protection control center is higher than control unit.
By the control of above fire-fighting control method, dual judgement can be passed through under the premise of not increasing extra cost
The control method of intelligentized extinguishment control system may be implemented in the reliability for effectively raising system, when temperature equivalence is extensive
After multiple normality, system is automatically stopped, and is effectively increased reliability while being reduced hardware cost.
