Abstract
The utility model discloses a coal mine wellhead wine measurer for safe production of coal mines, belonging to gas test device, which is composed of an alcohol detection probe for obtaining alcohol electric signals, an amplifying circuit for amplifying alcohol electric signals, a microprocessor, a signal output circuit, a sound light alarm circuit, a display for displaying processed result, a control receiving circuit for setting zero and sensitivity, a data memory circuit and a power circuit, wherein the alcohol detection probe, the amplifying circuit and the microprocessor are connected in turn, the signal output circuit, the sound light alarm circuit and the display are connected with corresponding output ports of the microprocessor. The utility model has the advantages that the coal mine wellhead wine measurer is arranged at the inlet of a tank chamber, to real-timely measure the alcohol concentration in the breath of workers, alarm via light and sound according to the concentrations and display result on a LED screen, thereby confirming safe production.
Description
Technical field
The utility model relates to a kind of gas determinator.Specifically be that a kind of coal mine well port that Safety of Coal Mine Production is used is surveyed the wine instrument.
Background technology
Be to guarantee Safety of Coal Mine Production, according to the regulation of " safe coal rules " the tenth: " go into and forbid to drink before the well personnel go into well ".But in practical operation, be difficult to implement completely because of lacking detection means.
Summary of the invention
The utility model provides a kind of coal mine well port to survey the wine instrument.This instrument can be placed in the porch of marquis's jar chamber, when going into the well personnel through this instrument, can measure and show the alcohol concentration in the well personnel implication in real time, and according to the size of setting concentration, produce the sound and light alarm signal, and the corresponding simulation value of output and alcohol concentration is presented on the LED screen.For Safety of Coal Mine Production provides safeguard.
The utility model is realized with following technical scheme: a kind of coal mine well port is surveyed the wine instrument, the amplifying circuit that amplifies by the alcohol detection probe that is used to obtain the alcohol electric signal, with the alcohol electric signal, microprocessor, signal output apparatus, sound light alarming circuit, display process result's display, is used to return to zero and control receiving circuit, data storage circuitry and the power circuit of sensitivity are formed; Alcohol detection probe, amplifying circuit, microprocessor connect successively; Signal output apparatus, sound light alarming circuit and display are connected with the corresponding output port of microprocessor.
The alcohol detection probe obtains the alcohol electric signal, and the A/D converter of alcohol electric signal input microprocessor after amplifying circuit amplifies is converted to digital quantity to analog quantity, starts each functional circuit according to the result who handles after microprocessor processes in good time.Demonstrate alcohol content as display.After the concentration of alcohol reached the alarm set point of setting, warning circuit sent warning.
The beneficial effects of the utility model are:
1, reliability height adopts New Type of Chip Microcomputer and high integrated digital circuit, makes circuit structure simple, and easy to use, dependable performance is convenient to safeguard.
2, highly sensitive, high performance sensing element adds the automatic nonlinear compensation of instrument internal software, makes instrument have higher sensitivity to the detection of alcohol.
3, stable performance, the sensing element of employing long-life, high stable and rational line design make the instrument serviceability very stable, and adjustment is simple and easy.
4, use extensively, be not only applicable to coal mine well port, also can be applicable to alcohol prohibition places such as traffic, engineering, workshop.
5, favorable expandability, this instrument can be associated with existing coal mine safety monitoring system by signal output apparatus, makes data directly be sent to relevant departments.
