Current household fire prevention market also not yet opens large market, its reason mainly: be first that product rate of false alarm is high; Two be cloth, inconvenience of withdrawing a garrison; Three is installations of home fire safety system, and present stage also needs installation and the service of professional contingent; Four is that price is general higher; Five information cannot exchange with extraneous in time.Although also have, some are powerful, operate very complicated, cause many users, and the old man especially in family is with bad or be simply reluctant use, and maintenance does not catch up with.

Utility model content

For the problems referred to above that prior art exists, the purpose of this utility model is: provide a kind of efficiency high, easy for installation, uses simple, is applicable to the domestic intelligent fire alarm system of most of family.

For achieving the above object, the utility model adopts following technical scheme: domestic intelligent fire alarm system, comprises induction system, signals collecting chip, controller, speech chip, coding and decoding chip and signal transmitting module; The signal output part of described induction system is connected with the signal input part of signals collecting chip; The described signal output part of signals collecting chip is connected with the signal input part of controller, the control signal output terminal of controller is connected with the control signal input end of speech chip, the voice signal output terminal of controller is connected with the signal input part of coding and decoding chip, and the signal output part of coding and decoding chip is connected with signal transmitting module.

As optimization, described induction system comprises microwave detector, pyroscan, smoke detector and hygrosensor; Described microwave detector, pyroscan, the smoke detector signal input part corresponding to signals collecting chip respectively with the signal output part of hygrosensor is connected.

Described microwave detector, pyroscan are arranged on by antitheft door and bedroom door respectively; Described smoke detector and hygrosensor are arranged on by the kitchen range top or high-power socket.

As optimization, described signals collecting chip adopts the single-chip microcomputer of msp430.

As optimization, described controller adopts AT89C52 single-chip microcomputer.

As optimization, described speech chip adopts ISD1420 speech chip.

As optimization, described coding and decoding chip adopts dtmf signal coding and decoding chip MT8888.

Relative to prior art, the utility model tool has the following advantages: the Design of Alarm System that the utility model provides is ingenious, structure is simple, mounting arrangements is convenient, based on the communication network of existing prosperity, efficiently, fast, economical, convenient, arrange simple and direct, workable, by configuring the warning function that just energy practical function is powerful simply, be convenient to popular popularization and use.During use, alerting signal sends by signal transmitting module, on the mobile phone being sent to resident family or other mobile terminals, increases alerting signal spread scope, improves the efficiency of warning by existing communication network; Integrated sensor cable device is set, improves the sensitivity of warning, decrease situation about misrepresenting deliberately as much as possible.

Accompanying drawing explanation

Fig. 1 is the structural representation of domestic intelligent fire alarm system of the present utility model.

In figure, induction system 10, microwave detector 11, pyroscan 12, smoke detector 13, hygrosensor 14; Signals collecting chip 20, controller 30, speech chip 40, coding and decoding chip 50, signal transmitting module 60.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

See Fig. 1, domestic intelligent fire alarm system, comprises induction system 10, signals collecting chip 20, controller 30, speech chip 40, coding and decoding chip 50 and signal transmitting module 60.

The signal output part of induction system 10 is connected with the signal input part of signals collecting chip 20;

The signal output part of signals collecting chip 20 is connected with the signal input part of controller 30, the control signal output terminal of controller 30 is connected with the control signal input end of speech chip 40, the voice signal output terminal of controller 30 is connected with the signal input part of coding and decoding chip 50, and the signal output part of coding and decoding chip 50 is connected with signal transmitting module 60.

Induction system 10 comprises microwave detector 11, pyroscan 12, smoke detector 13 and hygrosensor 14; Signals collecting chip 20 has multiple signal input part, and microwave detector 11, pyroscan 12, smoke detector 13 signal input part corresponding to signals collecting chip 20 respectively with the signal output part of hygrosensor 14 is connected.

Microwave detector 11, pyroscan 12 are arranged on by antitheft door and bedroom door respectively, can be accurately detected invader; Smoke detector 13 and hygrosensor 14 are arranged on by the kitchen range top or high-power socket, the source that initiation fire easily occurs near the kitchen range top or high-power socket, smoke detector 13 and hygrosensor 14 are arranged on the place of the easy breaking out of fire dangerous situation such as the kitchen range top or high-power socket side, whether Real-Time Monitoring surrounding environment has the situations such as temperature is too high, smog gas concentration exceeds standard, thus accurately and timely can detect the condition of a fire.

Signals collecting chip 20 can adopt the single-chip microcomputer of msp430, the AT89C52 single-chip microcomputer that controller 30 can adopt American ATMEL to produce, speech chip 40 can adopt the ISD1420 speech chip of American I SD company, the dtmf signal coding and decoding chip MT8888 that coding and decoding chip 50 can adopt Canadian Mitel company to produce, signal transmitting module 60 can adopt the wireless communication module of NRF905.

During concrete use: each detector in induction system is connected with signals collecting chip respectively, is carried out the collection of control data by signals collecting chip.Signals collecting chip by collect information transmission to controller.The information threshold that each detector institute detectable signal is corresponding is preset with in controller, when the information that arbitrary detector detects is more than or equal to information threshold corresponding to this information preset in controller, controller sends control signal to speech chip, speech chip will play the alarm sound recorded in advance, meanwhile alarm sound is also reached signal transmitting module by coding and decoding chip by controller, and signal transmitting module is sent to mobile phone or other mobile terminals of resident family again by existing communication network.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
