Multi-parameter sensor for GD5 coal mine

Abstract

The invention relates to a multi-parameter sensor for a GD5 coal mine. The multi-parameter sensor comprises a shell and a monitoring device, wherein the shell is provided with a handle; the shell comprises an upper shell and a lower shell; the upper shell is connected with the lower shell through a supporting arm; the upper shell is provided with a display window and an alarming window; the lower shell comprises a sensor containing cavity and gas monitoring cavities formed in the two sides of the sensor containing cavity; and the monitoring device comprises a battery, a sensor, a signal converter, a signal amplifier, a filter, a data acquisition card, a data storage device, a CPU (Central Processing Unit), a digital tube display, a signal chip microcomputer, an alarm, a wireless transmission module, an Internet network and a remote monitoring host. An electronic instrument, which adopts an electrochemical principle, and is intelligently controlled by an embedded type controller and displayed by a digital tube, is simple to operate, is convenient to use, is safe and reliable, and is mainly used for detecting and alarming methane, oxygen, carbon monoxide, hydrogen sulfide and carbon dioxide.

Description

technical field [0001] The invention relates to a gas detector, in particular to a GD5 multi-parameter sensor for coal mines. Background technique [0002] my country is the world's largest coal producer and consumer, and one of the few countries in the world that uses coal as its main energy source. In the process of coal mining, a variety of harmful gases coexist in the coal seam, such as CH4, CO, SO2, NH3, etc., the latter two gases have a small content and are soluble in water, which can be treated by spraying water; but the content of CH4 and CO It is a flammable and explosive gas, and the gas concentration reaches the explosion limit. When there is enough oxygen and an ignition source at a certain temperature, a gas explosion will occur, which will endanger the lives of coal miners. brought hidden dangers. The gas with high CO2 content, if the concentration is too high, it will affect people's breathing, and it is easy to cause suffocation and death. The content of ...

Problems solved by technology

[0003] At present, the existing various sensors have poor sensitivity and stability, short working hours, and are not suitable for mining in mines. At the same time, the detection range of dangerous gases is relatively small, which reduces the safety performance to a certain extent.
