Abstract
The utility model discloses a dangerous region automatic light sound alarm device, belonging to the alarm manufacture technical field, which comprises a power panel, a master switch, a voice acquisition board, a pickup device, a power amplifier board, a loudspeaker and an infrared sensor mounted at the back of the master switch. The dangerous region automatic light sound alarm device can be mounted in dangerous regions demanding protection to realize good safe protection effect.
Description
Technical field
The utility model belongs to the alarm manufacture technology field, is specifically related to a kind of hazardous location sound, light crossing-signal automatically.
Background technology
Carry out security protection in hazardous locations such as building, bridge, distribution, classic method is to set up to go along with sb. to guard him the safety that ensures people and equipment temporarily, when going along with sb. to guard him long-term use temporarily or changing, unsafe factor will occur, use to go along with sb. to guard him and also can cause the huge amounts of material waste because of geology.Therefore be badly in need of automatic sound, light crossing-signal that a kind of hazardous location in the needs protection can reach good security protection effect.
The utility model content
The purpose of this utility model is a kind of hazardous location of design sound, light crossing-signal automatically, power amplification plate, loudspeaker, D.C. regulated power supply can be bought small-size computer audio amplifier adapter kit on the market, voice collecting plate, acoustic pickup also can have been bought finished product, on the basis of these accessories, increase infrared inductor, realize the effect of automatic protection.
The utility model comprises: power panel, master switch, voice collecting plate, acoustic pickup, power amplifier plate, loudspeaker, and described alarm also comprises infrared inductor, described infrared inductor is installed in the back of master switch.
Described infrared inductor is infrared switch or infrared ray correlation device.
Described alarm also comprises alarm lamp.
Described power panel is the D.C. regulated power supply plate.
The utlity model has following beneficial effect: the utility model is installed in hazardous locations such as the building that needs protection, bridge, distribution, can reach good security protection effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is the utility model structural representation.The utility model comprises power panel 1, master switch 2, voice collecting plate 3, acoustic pickup 4, power amplifier plate 5, loudspeaker 6, it is characterized in that: described alarm also comprises infrared inductor 8, described infrared inductor 8 is installed in the back of master switch 2, alarm lamp 7, power panel 1 is the D.C. regulated power supply plate among Fig. 1.
Before being installed to the working-yard, after connecting all devices small-size computer audio amplifier power supply is inserted the 220V civil power, the audio amplifier volume switch is pushed minimum, pin typing button on the voice collecting wiring board, face toward acoustic pickup apart from 20CM left and right sides typing voice, to be used for the high voltage power distribution place such as equipment, can typing: " Keep Clear-High Voltage, please don't be close ".
After voice are recorded, erecting equipment is to the region that will monitor, good height of debugging and angle, when if infrared switch monitoring distance is not enough, can adopt the mode of parallel with infrared switch, the output that just will note infrared switch is consistent with input AC electricity phase place, if the monitoring distance uses infrared ray correlation product to replace infrared switch to connect greater than suggestion more than the 30M, mode of connection is constant.
Infrared switch is inserted the direct current safe voltage, power-on is opened volume switch, when the people passes through guarded region, the people knows from experience the specific wavelength infrared ray about emission 10um, whether just can detect this infrared ray pointedly with custom-designed sensor exists, when human body infrared shine on the sensor after, because of pyroelectric effect will outwards discharge electric charge, subsequent conditioning circuit handle after testing the back just can produce control signal.At this moment the D.C. regulated power supply in the infrared switch output terminal conducting small-size computer audio amplifier, electric power starting voice collecting device, power amplification plate, loudspeaker is finished the safety warning auditory tone cues, can install the dc low-voltage warning lamp additional in case of necessity.
The voice collecting device is the voice typing during typing button on pinning plate, and other times are for playing the good voice of typing.Voice amplify plate by the output terminal power input on the voice collecting wiring board and send the voice of typing through amplifying back promotion loudspeaker.
