Data acquisition and sending terminal with multiple gas detection capabilities

Abstract

The invention relates to a data acquisition and sending terminal with multiple gas detection capabilities. The data acquisition and sending terminal is technically characterized by comprising a powersupply module, a sensor module, an NB-IoT module and a pumping module, wherein the output end of the power supply module is connected with and supplies power to the pumping module, a three-in-one sensor module and a methane sensor module, the pumping module is connected with the sensor module, and the sensor module comprises the three-in-one sensor module and the methane sensor module; the three-in-one sensor module and the methane sensor module are connected with the NB-IoT module, and the NB-IoT module is connected with background equipment in an NB-IoT wireless mode. The hydrogen sulfide sensor, the oxygen sensor and the carbon monoxide sensor are integrated, the methane sensor and the temperature and humidity sensor are additionally arranged, the structure is compact, the size is small, the gas concentrations of the four kinds of common gas and the underground temperature and humidity can be monitored in real time, the detection efficiency is improved, and whether potential safetyhazards exist underground or not can be judged in time; and meanwhile, the cost is also reduced.

Description

Technical field[0001]The invention belongs to the field of gas detection technology, and relates to downhole gas detection technology, in particular to a data collection and sending terminal with multiple gas detection capabilities.Background technique[0002]The collection of various information on the coal mine site is very important for safe production, especially the concentration of carbon monoxide, oxygen, hydrogen sulfide and methane and other gases plays a vital role in production safety.[0003]In the existing coal mine underground field gas concentration detection technology, it is usually not possible to detect methane, hydrogen sulfide, oxygen, and carbon monoxide at the same time. Different configurations of A and B are required to detect oxygen and carbon monoxide, as well as methane and hydrogen sulfide. The problem of large volume and high testing cost.Summary of the invention[0004]The purpose of the present invention is to overcome the shortcomings of the prior art, and...
