Description
Technical field
The utility model relates to a kind of warning device, specifically, relates to a kind of fire alarm installation.
Background technology
Fire-fighting is closely bound up with people's life, work in the current society, and present, fire protection warning and fire-fighting equipment have all been arranged in nearly all office block and important place.This is protection people life property safety's important assurance.Fire fighting device adopts the linkage work pattern more, i.e. fire-fighting smoke intensity sensor sensing is just sent instruction to the condition of a fire and given centre panel, sends warning by centre panel again, also drives the fire water spray system simultaneously or fire-retardant gas is put out a fire.
Because all can produce smog after the breaking out of fire, so in order to prevent fire, existing office or commercial building generally all are equipped with " smoke transducer " to control terminal, are included in some smoking rooms, rest room etc., and purpose is the indoor smog that whether has because of the fire initiation of sensing.Its logic implication is that the existing smog of fire is arranged, as long as the feature of smog is arranged, control end will start the water spray or produce chimes of doom reminds the operator on duty to take measures.And existing fire protection warning device is the round-the-clock monitoring and protecting device of a cover, though have high sensitivity, can well disaster hidden-trouble be suppressed at bud.But also its good sensitivity just can cause unnecessary trouble equally in real work.Such as, when having personnel to smoke in the rest room or celebrating in banquet hall, again because people's tobacco habit can't avoid the time, will start smoke transducer immediately.Thereby the high sensor of sensitivity will be triggered, and control end also can send the instruction of water spray immediately; perhaps spray the anti-flammability gas of fire extinguishing usefulness; and the fire-suppressant gas of these high concentrations also can damage, and false alarm also usually can attract the fire fighter, makes people be in unusual awkward state.And address the deficiencies of the prior art; Usually all take to close the fire hazard aerosol fog sensor now, or the sensitivity of fire hazard aerosol fog sensor is turned down.Thus, so exactly when fire really takes place, these fire prevention devices are with ineffective and perform practically no function.Because of smoking causes the fire fighting device false alarm is a ubiquitous phenomenon now, and this has also increased many troubles for fire-fighting work.Not only can waste a large amount of human resources when handling similar problem, also because usually false alarm makes fire-fighting work produce bigger hidden danger to the sensation that people produce untrue " wolf has come " on the contrary.
The utility model content
A kind of fire alarm installation that the utility model provides has solved the problem of fire fighting equipment because of the smoking false alarm, allows the fire hazard aerosol fog sensor have simply " intelligence " recognition capability.
In order to achieve the above object, the utility model provides a kind of fire alarm installation, and the smog sensing device and the people's body heat that comprise the circuit connection are released infrared sensing device;
Described smog sensing device comprises infrared-emitting diode and infrared receiving diode, also comprises the grid type flue between infrared-emitting diode and infrared receiving diode;
When smog entered the smog sensing device, infrared light that infrared-emitting diode is launched made infrared receiving diode not receive infrared light through the refraction and the scattering of grid type flue, will output alarm signal; When not having cigarette in the smog sensing device, infrared receiving diode just can receive the infrared light that infrared-emitting diode sends, and does not promptly have alerting signal output;
Described smog sensing device also comprises two power supply signal wiring;
Described people's body heat is released infrared sensing device and is comprised people's body heat that circuit connects and release infrared sensor, triode and relay;
Described people's body heat is released infrared sensor and is comprised sensitive face, signal output, positive voltage input port and negative voltage input port;
The base stage of described triode connects the signal output that described people's body heat is released infrared sensor, and emitter connects negative voltage;
Described relay is connected between the collector and positive voltage of described triode, and the normally closed contact of described relay is connected on an end of the infrared receiving diode in the smog sensing device;
When people's smoking is arranged in the room, that is to say that the people in the room is in movable state, the sensitive face that the movable or meeting of moving of this human body be released infrared sensor by people's body heat receives, thereby cause that people's body heat releases the signal output of infrared sensor and produce high potential signal, make the triode conducting, thereby relay adhesive, its normally closed contact is disconnected, therefore the signal output of infrared receiving diode under alarm condition also disconnect, have the people to smoke (people is in active state) in the room although this just means, the triggering of alerting signal is prevented from also can not taking place chimes of doom and sprinkling fire-distinguishing agent;
When another kind of situation occurring, promptly in the room, fire has taken place, and the people of the inside has fallen in a swoon, and perhaps works as breaking out of fire, but have no talent in the room, at this moment people's body heat is released the sensitive face of infrared sensor just induction is less than physical activity in the room or mobile signal, and its signal output output signal is zero, and triode is in cut-off state, the electric power loop of relay just can't conducting, relay can't adhesive, and its normally closed contact is still closed, and the output port of infrared receiving diode is not disconnected; Simultaneously, after the cigarette that fire produces enters in the smog sensing device, the Infrared that infrared-emitting diode is launched by grid type flue refraction and scattering after seriously stopped, can not be received by infrared receiving diode, make fire-alarm be triggered, and export fire alarm signal and sprinkling fire-distinguishing agent to terminal by smoke alarm;
Described people's body heat is released infrared sensing device and is also comprised a transformer, the alternating current of 220V is converted to is applicable to that people's body heat releases the low tension of infrared sensing device;
A kind of fire alarm installation that the utility model provides, make the fire hazard aerosol fog sensor have simply " intelligence " recognition capability, i.e. identification has the sensitive zones of smog whether the people is arranged, someone does not promptly report to the police, if there is sensitive zones nobody of smog just to report to the police immediately, if someone zone has the smog descendant to escape or people's motionless (perhaps lying in a comatose condition) also reports to the police immediately, just do not report to the police when smokeless certainly, perhaps there is the people smokelessly also not report to the police.
