Description

Fire voice lead escape indicator

The utility model relates to a kind of guiding escape indicator, refers to a kind of fire voice guiding escape indicating device that can send the estranged route voice of escape according to the speech recording and reproducing device especially.

Because economy grows continuously and fast, society constantly advances, so living standards of the people constantly improve, and high buildings and large mansions stand in great numbers in the city, public place emerge in multitude like the mushrooms after rain constantly increases as office block, restaurant, department store, dancing hall, pub etc.When people just are being immersed in the cheerful and light-hearted atmosphere in visit market, or it is intoxicated in sweet song the time, often ignored the dire consequences of breaking out of fire in public places, in recent years, various public places of entertainment breaking out of fire and the accident of creating greater casualties happens occasionally, its main cause be in public places in during breaking out of fire, often unclear to landform and escape route because of everybody, cause disorder and disclose crowdedly mutually, rush and trample and cause the tragedy of injures and deaths.

The purpose of this utility model provides a kind of produced thick smoke or when infrared, ultraviolet before fire takes place, just can detect smog or infrared, ultraviolet in advance, pass the signal to other escape indicator by the ultrahigh frequency transmitting set, send the fire voice guiding escape indicating device of the estranged route voice of the escape of prerecording again according to the speech recording and reproducing device, in case thereby when avoiding the public place breaking out of fire, can reduce or avoid the generation of casualty accident greatly.

For this reason, the utility model is taked following technical scheme:

It is by the monocrystalline audio record circuit, the ultrahigh frequency transmitting set, the ultrahigh frequency radio receiver, flashing indicator, compositions such as smoke sensing device and speech amplifier, the output of described smoke sensing device connects the ultrahigh frequency transmitting set respectively, flashing indicator, the input of monocrystalline audio record circuit, the output of described ultrahigh frequency transmitting set connects the input of ultrahigh frequency radio receiver, the output of this ultrahigh frequency radio receiver connects the input of another flashing indicator, it is exported and the brilliant audio record circuit input of order, and this monocrystalline audio record circuit output links to each other with loudspeaker through speech amplifier.

Its principle of work is, at first prerecord voice in monocrystalline speech recording and reproducing integrated circuit chip IC1 according to various buildings landform and escape route, recorded speech is as " please turn left to keep straight in the fire generation and can run away to escape stair " or " please turn right in the fire generation and advance and can escape to emergency door " or " the escape emergency door is at this " ... Deng the circulation voice.

Before taking place, fire will inevitably send dense smoke, infrared, ultraviolet ray, and the smog in the utility model or infrared, ultraviolet ray inductor automatically can be in advance with the smog that is sent before the fire generation, infrared, ultraviolet ray detection arrives, in case detect, promptly radio signal is passed in the ultrahigh frequency radio receiver 3 by ultrahigh frequency transmitting set 2, when ultrahigh frequency radio receiver 3 receives radio signal, flashing indicator 4 can start and flash of light automatically, guide escape direction simultaneously and make monocrystalline audio record circuit 1 ' send escape route circulation voice, the speech amplifier of adjusting through the built-in volume 6 links to each other with loudspeaker 7 simultaneously, and sends voice; Above-mentioned inductor 5 detects smog or ultrared while, and the voice system that starts monocrystalline audio record circuit 1 simultaneously sends voice.

Because above-mentioned enabling signal is the ultrahigh frequency radio signal, the configuration installation and the link process of indicator so can conveniently escape, need not consider the restriction on the buildings landform, when the radio transmission distance (for example from Stall to two the 10th buildings), signal weakens, when signal changes weak, can seek a relay station and transfer, signal is strengthened.Moreover enabling signal is that wireless remote control mode (ultrahigh frequency radiowave) also can change wired load mode into.

The utility model fire voice guiding escape indicator, in the time of can before fire takes place, sending dense smoke, just all can be installed on same the fire voice guiding escape indicator in the building starts, except the flash of light indication, can also send the voice guide escape route, do not cause personnel to lose directivity, really can reach the estranged personnel's of quick guide purpose, make injures and deaths reduce to minimum.
