Abstract
Provided is a methane-carbon monoxide dual-purpose measuring apparatus including a sensing element for detecting methane, an amplifying circuit, a converting circuit, a microprocessor, an alarm circuit, a display circuit and a power supply circuit. The measuring apparatus is hung at a place which needs to be detected. When the concentrations of methane and carbon monoxide in air exceed set alarm points, the alarm circuit gives an alarm, and a displayer displays the concentration values of methane and carbon monoxide in the current air.
Description
Technical field
The present invention relates to a kind of apparatus for determination of gas, the analyzer of especially a kind of methane and two kinds of gases of carbon monoxide.
Background technology
Gas and carbon monoxide are the accompaniments of coal mining, and gas explosion is one of the disaster in colliery, and the serious threat Safety of Coal Mine Production is also the emphasis of respectively mining state's research and prevent in the world today.The gas principal ingredient is alkane, and wherein methane accounts for the overwhelming majority, and a small amount of ethane, propane and butane are separately arranged, and generally also contains in addition sulfuretted hydrogen, carbon dioxide, nitrogen and aqueous vapor, and the inert gas of trace, as helium and argon etc.Under the status of criterion, methane to butane exists with gaseous state, and pentane is above is liquid.As naked light, " gas " blast, occur, the life security that is directly threatening the miner in incendivity.The methane analyzer that at present colliery is used is mostly portable, and the circuit of known portable analyzer is by sensing element at present, amplifying circuit, and A/D change-over circuit, single-chip microcomputer, signal output apparatus, sound light alarming circuit, display circuit forms; Can singlely carry out continuous detecting to methane and carbonomonoxide concentration respectively.But obtain the common gas sensor of the general employing of sensing element that signal is used, the battery capacity that power acquisition is used is little, and display is little unintelligible, and its shortcoming is sensitivity and poor stability; Working time is short; Be not suitable for being suspended on the upper corner position under getting working face under mine, particularly mine.
Summary of the invention
Methane carbon monoxide tester of the present invention is for above deficiency, and a kind of reasonable in design, simple in structure, long service life is provided, and can detect two kinds of gases of methane and carbon monoxide.
The technical solution adopted for the present invention to solve the technical problems is: the dual-purpose analyzer of a kind of methane carbon monoxide is determined device, comprises and detects the sensing element that methane is used, amplifying circuit, change-over circuit, microprocessor, warning circuit, display circuit and power circuit;
Sensing element, amplifying circuit, A/D change-over circuit, microprocessor connect successively;
Warning circuit, display circuit connects with the corresponding interface of microprocessor;
The methane sensing element is the black and white heat catalytic element; Carbon monoxide is electrochemical element; Display circuit adopts two row, four 2.3 cun red digital display tubes, high-visible in 30 meters, detects methane, carbonomonoxide concentration simultaneously, large decibel, and the high brightness alarm mode, the telepilot calibration, power supply is the 3.6^ Ni-MH battery.
Compared with prior art, the invention has the beneficial effects as follows: instrumental sensitivity is high, and two row, four 2.3 cun red digital display tubes are high-visible in 30 meters, detect methane, carbonomonoxide concentration, large decibel, high brightness alarm mode simultaneously, the telepilot calibration, good stability, stream time is long.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, patent of the present invention is further illustrated.
Fig. 1 is the schematic diagram of the dual-purpose analyzer of methane carbon monoxide;
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described.
Analyzer is hung on and needs the place of detecting, the concentration value of methane and carbon monoxide in the rear Real-Time Monitoring environmental ambient air of start.When Methane in Air and carbonomonoxide concentration surpass the alarm set point arranged, warning circuit is reported to the police, and display shows current Methane in Air and carbonomonoxide concentration value.Because black and white heat catalytic element and electrochemical element have highly sensitively than traditional gas sensor, anti-methane high concentration impact is good, therefore the good stability of instrument; Power supply is the 3.6V Ni-MH battery, durable, and the working time is 24 hours.
