Abstract

A temperature sensor, a smoke broadcaster, a carbon monoxide sensor and an infrared sensor are controlled by a single chip microcomputer, and the temperature value, the smoke concentration value, the gas concentration value, and whether there is someone breaking in are displayed on a liquid crystal display in real time. If a host is at home (set by a button), the voice broadcasts 'The current indoor temperature is too high, please be careful of fire!' when the temperature is too high, the voice broadcasts 'There is smoke inside now, please check whether there is fire!' when the concentration of smoke is too high, the voice broadcasts 'The concentration of gas is too high inside, please check whether there is gas leakage and ventilate the room and close the valve in time!' when the concentration of leakage gas is too high, and the voice broadcasts 'Someone breaks in!' when someone breaks in. If the host is not at home (set by the button), when these happen, texts in the voice information can be sent to the host through a GSM module.

Description

Based on the design of single-chip microcomputer domestic intelligent safety-protection system
Technical field
The present invention relates to domestic security system regions, relate to the design of intelligent domestic safety-protection system particularly.
Background technology
Along with the raising day by day with living standard that develops rapidly of society, liquefied petroleum gas (LPG), piped gas or rock gas have entered most urban family, the life of people simultaneously also be unable to do without household electrical appliances miscellaneous, although these things bring many changes to everybody life, too increase the danger of fire and gas poisoning.Meanwhile, the fast development of modern city adds many new difficult problems, and the case such as burglary, robbery often occurs, and increasing people are in the urgent need to the living space of a safety.Now main safeguard procedures are protected house by burglary-resisting window or anti-theft net, although it has certain anti-theft effect, very unsightly, also brings more security risk, so domestic intelligent safety-protection system arises at the historic moment.
Summary of the invention
Main design thought of the present invention is by Single-chip Controlling temperature sensor, smoke alarm, carbon monoxide transducer and infrared sensor, wherein temperature, smokescope and gas concentration value and whether someone swarms into is presented in LCDs in real time.If owner is in (by key assignments), when temperature is too high, voice broadcast: current indoor temperature is too high, Practice fire prevention; When smokescope is too high, audio alert: current indoor has smog, notes whether catching fire; When gas leakage excessive concentration, audio alert: indoor fuel gas excessive concentration, notes gas leakage, ventilates in time and valve-off.When someone swarms into, audio alert: have people to swarm in family.If owner stays out (by key assignments), there is above situation, can gsm module be passed through, the word in above voice messaging is sent to owner.
Based on requirement of system design, in order to meet the function of each several part, several simple module can be divided into.Module one is by the single-chip minimum system formed based on AT89S52 single-chip microcomputer, and this system, as control core, is the brain of whole intelligent system, makes it control the operation of each functional module by program.It is made up of crystal oscillating circuit, single-chip microcomputer and reset circuit.Module two is smoke detection systems, and Smoke Detection detects the first whether room catches fire, and by Smoke Detection, can know and have a large amount of smog to produce in room, thus carry out the prevention of fire.This module is made up of smoke transducer and Smoke Detection circuit.Module three is gas leakage detection systems, CO gas sensor is the core detecting element in this testing circuit, the gas sensor used, when carbon monoxide and sensor contacts, sensor can export corresponding magnitude of voltage according to the difference of concentration, and magnitude of voltage is sent into A/D converter, subsequently by single-chip microcomputer process data, the concentration value that final basis calculates and predetermined value compare to judge whether to report to the police.Module four is temperature monitoring system, employing be DS18B20 single bus sensor.This module is for monitoring the height of indoor temperature.Module five is burglary-resisting system, is monitored by pyroelectric infrared sensor, and whole house can be covered in an invisible net, when burglar enters from window, sensor will respond, and is passed in single-chip microcomputer by a pulse signal rapidly and report to the police.Core component is BISS0001, and it is a transducing signal process integrated circuit with superior performance, and it is equipped with the pyroelectric infrared switch of pyroelectric infrared sensor and a small amount of outward element formation passive type.Be applicable to the automatic light of safety zone, illumination and warning system.Module six is voice broadcasting systems, and after each sensor collects data and passes to single-chip microcomputer, if when exceeding or reach some requirement, warning circuit then starts response.What usual use was maximum is hummer, although sound only has a sound of reporting to the police very greatly, cannot carry out different voice messages, very inapplicable at native system, therefore adds audio alert while use hummer, reports different voice according to different events.Module seven is gsm system, is made up of TC35i, power circuit, startup and shutdown circuit, datel circuit, voice communications circuit and SIM card circuit.If owner stay out can by this module by the information feed back of family to owner.Module eight is set as backup system, and by liquid crystal indicator, key device forms.Module nine is electric power system, for whole system provides electric power support.

Embodiment
For making content of the present invention clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 2, a kind of domestic intelligent safety-protection system provided by the present invention, it is characterized in that, comprising: mainboard (1), smoke detection system (2), gas leakage detection system (3), system for detecting temperature (4), electric power system (5), charging port (6), switch (7), liquid crystal indicator (8), single-chip minimum system (9), burglary-resisting system (10), voice broadcasting system (11), gsm system (12), key system (13); Wherein smoke detection system (2), gas leakage detection system (3), system for detecting temperature (4), electric power system (5), liquid crystal indicator (8), single-chip minimum system (9), burglary-resisting system (10), voice broadcasting system (11), gsm system (12), key system (13) are arranged on above mainboard (1), and charging port (6), switch (7) are arranged on side.
As shown in figure, after switch opens, electric power system will start power supply for other system, can arrange in family whether have people by key system.When having people in manager, the information collected is input in single-chip minimum system (9) by smoke detection system (2), gas leakage detection system (3), system for detecting temperature (4), burglary-resisting system (10), single-chip minimum system (9) process after by current information displaying within doors on liquid crystal indicator, owner can be reminded by voice broadcasting system when dangerous.In manager during no one, by gsm system (12), information can be sent to owner.
