CJY4/25X suspension type methane and oxygen measuring device

Abstract

The invention provides a CJY4 / 25X suspension type methane and oxygen measuring device. Air information firstly received by a methane sensor and an oxygen sensor is transmitted to a catalytic sensor; the air information is transmitted to a wireless receiving and transmitting module through the catalytic sensor, transmitted to an A / D converter through the wireless receiving and transmitting module and converted into a digital signal through the A / D converter; the digital signal is transmitted to a single-chip microcomputer and digitally processed, the digital signal digitally processed through the single-chip microcomputer is transmitted to a controller, and after the digital signal is processed through the controller, a corresponding methane concentration value and a corresponding oxygen concentration value are displayed in a digital mode; safety performance is higher, performance is stable, a threshold is accurate, responses are quick, and precision is high. Meanwhile, the overall operation is easy, use is convenient, the structure is novel, appearance is unique, the size is small, the weight is low, the device is convenient to carry, the functions are diversified, use time is long, the detection range is wide, and requirements of manufacturers can be better met.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a CJY4 / 25X suspended methane oxygen detector. Background technique [0002] The methane oxygen detector is an intelligent, multi-functional, ultra-small digital methane (gas) concentration and oxygen concentration detection and alarm instrument. It is mainly suitable for places where there is a risk of gas explosion in coal mines, such as coal mine lanes, mining faces, and goafs. , Return air lane, belt transport lane, electromechanical cavern, etc., continuously detect the concentration of methane and oxygen. When the methane concentration and oxygen concentration exceed the limit, the detector will immediately sound and light alarm, which can be carried by cadres, ventilation management personnel, gas detectors, blasters, mining face workers, etc. The existing methane oxygen measurement The alarm function of the device is single, the working time is short, and the detection ...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a CJY4 / 25X suspended methane oxygen detector, which solves the problem of the existing methane oxygen detector with single alarm function, short working time, small detection range, and reduced safety performance to a certain extent.
