Abstract
The invention discloses
A kind of coal gas detection and early warning system, including single chip control module, gas sensor module, A/D converter module, operational amplifier module, sound and light alarm module, numeral method module, ventilation fan module, it is characterised in that：The single chip control module connects gas sensor module, A/D converter module, operational amplifier module, sound and light alarm module, numeral method module, ventilation fan module respectively；The numeral method module connects numeral method device；The sound and light alarm module connects audible-visual annunciator；The gas sensor module connects sensor by A/D converter module；The ventilation fan module connects ventilation fan and valve.In the present invention, MQ-5 has more outstanding antijamming capability for other sensors and screens the respond of gas faster；The characteristics of having long service life and reliable stabilization；Test circuit is fairly simple.
Description
Technical field
The present invention relates to one kind detection and early warning system, more particularly, to a kind of detection of coal gas and early warning system.
Background technology
In the modern society that economy is developed rapidly,
People propose requirement higher to oneself the standard of living, animation, living environment, and in family the security context in room especially conventional gas of indoor day is then more exposed to pay attention to safely.
2003
Year, the Chinese government promulgated file,
Point out that indoor pollution will produce serious negative effect to health of people situation, extensive concern of the various circles of society to indoor gas safety problem is caused, also to production firm's huge business opportunity and good development environment of band of each indoor gas safety verification detecting instrument.In the past, most of families all do not process the standard security means of gas leakage, and daily check valve is also just accomplished by the best family of awareness of safety, it is known that to accomplish not electricity consumption, not strike sparks in the event of leakage, windowing ventilation etc., preparation fire extinguisher of at most staying at home again.But when leakage accident really occurs, a lot of people cannot cool down, in addition can habitually turn on light, make a phone call alarm etc., cause catastrophic consequence.It can be seen that one of security guard for being prevented trouble before it happens as home-use gas of gas leak detector, with very important status.
The content of the invention
It is an object of the invention to provide a kind of respond for screening gas with outstanding antijamming capability and faster；A kind of coal gas detection of the characteristics of having long service life and reliable stabilization and early warning system.
The present invention is achieved by the following technical solutions：A kind of coal gas detection and early warning system, including single chip control module, gas sensor module, A/D converter module, operational amplifier module, sound and light alarm module, numeral method module, ventilation fan module, it is characterised in that：The single chip control module connects gas sensor module, A/D converter module, operational amplifier module, sound and light alarm module, numeral method module, ventilation fan module respectively；The numeral method module connects numeral method device；The sound and light alarm module connects audible-visual annunciator；The gas sensor module connects sensor by A/D converter module；The ventilation fan module connects ventilation fan and valve.
Single chip control module of the present invention uses AT89S52 single-chip microcomputers.
Sensor of the present invention uses semiconductor gas security MQ-5.
Operation principle of the invention：It is the control core of system that the present invention uses AT89S52 single-chip microcomputers, and surrounding environmental gases information is gathered with semiconductor gas security MQ-5, and the analog signal that will be collected carries out analog/digital conversion, transfers to single-chip microcomputer to process the digital quantity after conversion by A/D converter.Then single-chip microcomputer is according to parts such as output control charactron numerical monitor, valve, the fans for obtaining.By sensing acquisition combustable gas concentration parameter value, by a series for the treatment of, the critical value being previously set in the result for most obtaining at last and single-chip microcomputer is compared system.If concentration is higher than given threshold, start fan to change indoor hazardous gas concentration, close fuel gas safety valve, start sound light alarming circuit, and show room gas concentration change in real time, waiting house-owner carries out final process.
The beneficial effects of the present invention are：
In the present invention, MQ-5 has more outstanding antijamming capability for other sensors and screens the respond of gas faster；The characteristics of having long service life and reliable stabilization；Test circuit is fairly simple.
