Abstract
The utility model provides a household combustion gas leakage safety device. The household combustion gas leakage safety device comprises a sensor, an A/D converter, a one-chip microcomputer, a keyboard control unit, an acousto-optic alarm unit, a relay, a solenoid valve and an exhaust fan, wherein the sensor, the A/D converter and the one-chip microcomputer are connected in order, the keyboard control unit, the acousto-optic alarm unit and the relay are respectively connected with the one-chip microcomputer, and the relay is connected with the solenoid valve and the exhaust fan. The household combustion gas leakage safety device can not only detect leakage of combustion gas accurately and timely, but also automatic emergency processing can be further realized including exhaust and closing the valve to cut off a gas source; self-check and alarm can be carried out after damage to the sensor, so a user can timely discover the damage and carry out self-replacement; a valve closing/opening device has special design; dismounting of an original pipeline is not required during mounting; use is convenient; and the household combustion gas leakage safety device is especially applicable to use of an unconditionally-established or cluster adding monitoring system for general combustion gas users.
Description
Technical field
The utility model relates to technical field of security and protection, and a kind of household gas leakage safety device is provided.
Background technology
Along with popularizing of cities and towns pipe natural gas, coal gas or bottled gas, the gas leakage blast or the intoxication accident that cause due to improper use and ageing equipment happen occasionally, and therefore fuel gas alarm are installed and are more and more come into one's own.
Yet, the development of fuel gas alarm is very uneven at present, though by PC large-scale cluster monitoring system advanced technology on duty but expensive, must establish Special machine room and personal management, usable range be confined to condition better, residential quarter or unit that the estate management level is higher.And mostly there are some defectives in general fuel gas alarm, some function singlenesses, and poor reliability, sensor damages and is difficult for finding, can not change.Some product utilization gas pipeline special electromagnetic valves are controlled source of the gas, and its installation need be torn former pipeline open, must submit a report asking for gas company and send the special messenger to process, and very trouble, therefore also embarrass users used.
Summary of the invention
The purpose of this utility model is to provide a kind of household gas leakage safety device, this system can not only detect the leakage of combustion gas timely and accurately, carry out sound and light alarm, can also realize automatic emergency processing (comprising that air draft and valve-off cut off source of the gas), sensor damages the energy self-checking alarming, the user can in time find and the energy self-changeable, is particularly suitable for unconditionally setting up or adds the vast gas user of cluster monitoring system to use.
The utility model is by the following technical solutions to achieve these goals:
A kind of household gas leakage safety device, it is characterized in that: comprise sensor, A/D converter, single-chip microcomputer, Keyboard Control unit, acousto-optic warning unit, relay, solenoid valve and exhaust fan, described sensor, A/D converter, single-chip microcomputer are linked in sequence, described Keyboard Control unit, acousto-optic warning unit and relay all are connected with single-chip microcomputer, described relay connected electromagnetic valve and exhaust fan.
In such scheme, described single-chip microcomputer adopts chip AT89C51.
In such scheme, described sensor adopts SnO2 type gas sensor.
The utility model installs at diverse location concentration and the flow that gas sensor detects combustion gas, gather live signal and send into A/D converter, supply the single-chip microcomputer retrieval and inquisition after being converted to digital signal, single-chip microcomputer is to carrying out software filtering, analysis and calculation from the signal after sensors A/D conversion, and be converted into concentration, detect simultaneously the purpose that the Keyboard Control signal has reached Real Time Monitoring.The alarming value output alarm signal that the data that single-chip microcomputer detects when the gas leakage of certain road have surpassed its setting drives audible-visual annunciator and reports to the police, and shut electromagnetic valve cuts off source of the gas simultaneously, opens exhaust fan.
Because the utility model adopts above technical scheme, so possess following beneficial effect:
The utility model can not only detect the leakage of combustion gas timely and accurately, carry out sound and light alarm, can also realize automatic emergency processing (comprising that air draft and valve-off cut off source of the gas), sensor damages the energy self-checking alarming, the user can in time find and the energy self-changeable, valve opening and closing device design uniqueness, and installation need not to tear open former pipeline, therefore use very conveniently, be particularly suitable for unconditionally setting up or add the vast gas user of cluster monitoring system to use.
