Description

The family expenses fire disaster alarming device

Technical field

The utility model relates to a kind of fire disaster alarming device, particularly relates to a kind of family expenses fire disaster alarming device.

Background technology

Fire is different from other city disasters, and it has characteristics such as sudden, randomness.In case breaking out of fire is puted out a fire to save life and property untimely, will bring loss to the people's lives and property.Because the frequency of fire failure generation in recent years constantly increases, fire has become the No.1 factor of current threat urban safety.Do the early warning work of fire well, be the focus that governments at all levels pay close attention to all the time, and in municipal fire-fighting construction, occupy an important position.

Traditional family expenses fire disaster alarming device often adopts single mirror formula to report to the police, and only selects a parameter as monitored object, fails to report so often cause.For example, for the category-A fire, it is more to produce smog, and temperature variation and not obvious.If merely temperature is monitored, be difficult to find environmental abnormality.

Traditional family expenses fire disaster alarming device has often only been installed a sensor, is " some monitoring " mode, can only detect the environmental abnormality of its peripheral region like this, and fire place on fire comparatively disperses in the actual life.If kindling point is far away from the prior-warning device distance, then have only behind fire spread and just can sense environmental abnormality, so just wasted valuable time, the difficulty of putting out a fire to save life and property is strengthened.

Traditional family expenses fire disaster alarming device often can not in time allow owner obtain alerting signal, a kind of situation is for just sound and light alarm or loudspeaker are reported to the police at home, under the unmanned state, will not receive alerting signal, can not in time take corresponding precautionary measures, delay the valuable relief time; Though another kind of situation is to have adopted the automatic dialing alarm function, automatically dial the number that owner pre-sets by phone, give master alarm, in case but the phone ring unanswered that owner sets in advance, owner just can not in time obtain condition of a fire information, in time takes the fire fighting measure.

The utility model content

The purpose of this utility model is to fail to report easily for solving present family expenses warning device, only adopts " some monitoring " mode, and can not in time allow owner obtain the problem of alerting signal, and a kind of family expenses fire disaster alarming device is provided.

The utility model is made up of master control set, a plurality of probe, loudspeaker and telephone set,

Probe comprises temperature sensor and smoke transducer,

Master control set is made up of single-chip microcomputer, indoor signal receiver module, indoor signal transmitter module, indoor warning dialing chip, neighbours' signal receiving module, neighbours' signal emission module and the neighbours dialing chip of reporting to the police,

The indoor signal receiver module receives the signal that each probe wireless radio transmission is come, the output terminal of indoor signal receiver module links to each other with the input end of single-chip microcomputer, an output terminal of single-chip microcomputer links to each other with the input end of neighbours' signal emission module, this machine of neighbours' signal emission module radio transmission alerting signal, another output terminal of single-chip microcomputer links to each other with the input end of indoor signal transmitter module, an output terminal of indoor signal transmitter module links to each other with loudspeaker, another output terminal of indoor signal transmitter module links to each other with the input end of indoor warning dialing chip, the output terminal of indoor warning dialing chip links to each other with telephone set

Neighbours' signal receiving module receives neighbours' alerting signal, and the report to the police input end of dialing chip of the output terminal of neighbours' signal receiving module and neighbours links to each other, and report to the police the dial output terminal of chip of neighbours links to each other with telephone set.

Advantage of the present utility model:

What 1, the utility model adopted is the double-identifying type type of alarm, and environment temperature and smokescope are monitored simultaneously, as long as a parameter variation abnormality is arranged, just can drive warning circuit work.Two parameters of temperature and smokescope have formed good complementary relationship, and the parameter that has contained three class fire changes, thereby greatly reduces rate of failing to report;

2, the utility model adopts " network monitor " mode, can monitor indoor environmental abnormality everywhere, in case the variation abnormality of any point just can start alert program.So just guaranteed that information is transferred to owner in the very first time;

3, the utility model is not only given master alarm, and gives neighbours' telephone call that same prior-warning device is housed, and so always someone will to receive fire information, in time takes disaster relief measure.
