Abstract
The invention relates to the technical field of fire control, and specifically relates to a household smoke alarm based on a single-chip microcomputer. The smoke alarm based on a single-chip microcomputer is composed of a data acquiring and processing unit, a single-chip microcomputer and an output unit, wherein the data acquiring and processing unit and the output unit are connected with the single-chip microcomputer. The smoke concentration value of the environment is displayed directly through a liquid crystal display, so that users or people rushing to the site can directly know the smoke concentration value of the environment and make better and more appropriate judgment and treatment, and the function of smoke detection is achieved. The smoke alarm of the invention has the advantages of simple structure, accurate test results, convenient use and easy promotion.
Description
Technical field
The present invention relates to technical field of fire control, be specifically related to the SCM Based smoke alarm of a kind of domestic.
Background technology
In recent years, the annual breaking out of fire 600 ~ 7,000,000 in the whole world, wherein home fire accounts for more than 80%. Report " American family fire hazard aerosol fog alarm " finds according to statistics: in the fire of every 1000 reports, if having smoke alarm and wet sprinkler to exist, the mortality rate that fire causes just can reduce by 84%. The external installation to family fire alarming system early has started to promote and carry out, and has many countries to perform with corresponding laws and regulations strict regulations. And house part is not installed automatic fire alarm system and is had defined by existing " Code for fire protection design of buildings " (GB50016-2006) of China. Finding by investigating, existing smoke detector easily lost efficacy, connected disconnection or cell damage, lacks battery undervoltage detection, there is the situation of false alarm, and work extremely unstable.
Summary of the invention
It is contemplated that propose a kind of Domestic smoke alarms.
Technical program of the present invention lies in:
SCM Based smoke alarm, is made up of data acquisition process unit, single-chip microcomputer, output unit; Wherein, data acquisition process unit and output unit are all connected with single-chip microcomputer.
Preferably, described data acquisition process unit is the Smoke Sensor, amplifying circuit and the A/D change-over circuit composition that are sequentially connected with.
Preferably, described output unit is made up of two parts, respectively 1602 liquid crystal displays and sound light alarming circuit.
It is highly preferred that described sound light alarming circuit is made up of 555 intervalometers, speaker and common light emitting diode.
Or preferably, it is additionally provided with adjustment valve, is connected with single-chip microcomputer.
Or preferably, it is additionally provided with ventilation fan, is connected with single-chip microcomputer.
Or preferably, described amplifying circuit is made up of LM324 integrated circuit.
It is highly preferred that described Smoke Sensor model is QM-N5.
The method have technical effect that:
Liquid crystal of the present invention directly displays the smokescope value in environment, allows user or the people that is on the scene can directly know the smokescope value in environment, in order to makes better, more suitably judges and process, it is achieved that the function of Smoke Detection. Present configuration is simple, and test result is accurate, convenient use, it is easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of the SCM Based smoke alarm of the present invention.
Detailed description of the invention
Fog siren.
Technical program of the present invention lies in:
SCM Based smoke alarm, is made up of data acquisition process unit, single-chip microcomputer, output unit; Wherein, data acquisition process unit and output unit are all connected with single-chip microcomputer. Wherein, data acquisition process unit is the Smoke Sensor, amplifying circuit and the A/D change-over circuit composition that are sequentially connected with. Output unit is made up of two parts, respectively 1602 liquid crystal displays and sound light alarming circuit. Sound light alarming circuit is made up of 555 intervalometers, speaker and common light emitting diode. It is additionally provided with adjustment valve, is connected with single-chip microcomputer. It is additionally provided with ventilation fan, is connected with single-chip microcomputer. Amplifying circuit is made up of LM324 integrated circuit. Described Smoke Sensor model is QM-N5.
Undertaken by sensor that signals collecting is then passed to pre-amplification circuit, analog to digital conversion circuit transducer is given single-chip microcomputer and processed, thus deciding whether to report to the police. In the design by the 1602 real-time display density of liquid crystal and alarm condition, adopt buzzer and LED as alarm signal simultaneously. Simulate with Single-chip Controlling relay and control scavenger fan and regulate the duty of valve, allow system automatically start associated safety feature while reporting to the police.
Circuit is used LM324 integrated circuit as the operational amplifier of circuit. Also increase reference voltage due to amplifying circuit, introduce zero point regulatory function, so can adjust the Zero change problem owing to different sensors causes more easily.
