Problems solved by technology

However, in actual use, this method has the following problems: the environmental conditions in the well (ie parameters such as humidity, temperature, carbon monoxide, methane, carbon dioxide, and oxygen) are constantly changing, and recorders need to go back and forth many times to modify the whiteboard. Parameter information not only consumes a lot of manpower and material resources, but also has high cost and low work efficiency, and there are accidents caused by untimely update of parameters, and the safety factor is low

Abstract

The invention discloses an underground coal mine real-time display device which comprises a PJD127V-6 flameproof and intrinsic safety type multi-parameter recording display screen (1). The PJD127V-6 flameproof and intrinsic safety type multi-parameter recording display screen (1) comprises an intrinsic safety power supply switching circuit, a first power supply switching circuit, a single-chip microcomputer I, a temperature and humidity collecting circuit connected with the single-chip microcomputer I, a first infrared remote control receiving circuit, a first nixie tube display circuit, a second nixie tube display circuit and a third nixie tube display circuit. Underground environment states such as humidity, temperature, carbon oxide, methane, carbon dioxide and oxygen can be displayed and can be conveniently checked by passing miners; all pieces of parameter information can be changed in time according to the environment real-time changes, and the passing miners can see the newest and more accurate information; cost is reduced, and the work efficiency and safety are improved.

Description

technical field [0001] The invention relates to a display device, in particular to a coal mine underground real-time display device, which belongs to the technical field of coal mine display equipment. Background technique [0002] At present, in order to ensure the safety of underground work in coal mines and facilitate underground workers to know the environmental conditions such as underground humidity, temperature, carbon monoxide, methane, carbon dioxide, and oxygen in a timely manner, there are generally black pens and whiteboards installed underground. By writing the values ​​of various environmental parameters on the whiteboard Reminders on the website and for passing miners to check. However, in actual use, this method has the following problems: the environmental conditions in the well (ie parameters such as humidity, temperature, carbon monoxide, methane, carbon dioxide, and oxygen) are constantly changing, and recorders need to go back and forth many times to mod...
