Downhole intelligent monitoring system based on Internet of Things

Abstract

The invention provides a downhole intelligent monitoring system based on the Internet of Things. The downhole intelligent monitoring system comprises a display, a ground control module, a downhole control module, a ground communication module, a downhole communication module, a dust concentration sensor, a CO concentration sensor, a fan variable-frequency control mechanism and a spraying device. The downhole control module obtains downhole dust and CO concentration through the dust concentration sensor and the CO concentration sensor, and when the downhole dust and CO concentration exceed threshold values, the downhole control module starts the spraying device and the fan variable-frequency control mechanism to conduct dust removal, dust falling and ventilation operation. The downhole control module transmits dust and CO concentration information to the ground control module through the downhole communication module and the ground communication module, and the ground control module displays related data on the display. According to the invention, the full-automatic operation of reducing the concentration of dust and CO in the mine production operation is realized, the generation of dust and CO in the downhole production operation is inhibited from the source, the burden of workers is reduced, and the health of the workers is guaranteed.

Description

technical field [0001] The invention belongs to the field of mining production operations, and in particular relates to an intelligent monitoring system based on the Internet of Things. Background technique [0002] At present, most mines are prone to generate a large amount of dust and toxic gases on the road surface when they are transported in the mine, which seriously threatens the physical and mental health of the workers, increases the wear and tear of mechanical equipment, and pollutes the surrounding ecological environment. Accidents, seriously affecting transportation and labor productivity. Measures such as atomized water for dust reduction have not been widely used due to problems such as complex preparation process, single application conditions, and corrosion pollution. At present, artificial timed water spray measures are mainly used, and the hazards of road dust still exist. However, in the underground mining working face, a large amount of dust will still be...

AI Technical Summary

Problems solved by technology

[0002] At present, most mines are prone to generate a large amount of dust and toxic gases on the road surface when they are transported in the mine, which seriously threatens the physical and mental health of the workers, increases the wear and tear of mechanical equipment, and pollutes the surrounding ecological environment. Accidents, seriously affecting transportation and labor productivity

Measures such as atomized water for dust reduction have not been widely used due to problems such as complex preparation process, single application conditions, and corrosion pollution. At present, artificial timed water spray measures are mainly used, and the hazards of road dust still exist

However, in the underground mining working face, a large amount of dust will still be generated at the operation site, and the existing detection methods and dust removal and dust reduction facilities cannot exert ideal performance at the operation site with complex working conditions

At present, the artificially controlled dust suppression facilities arranged underground increase the workload and danger of on-site personnel, and cannot suppress the initial stage of dust concentration increase from the source, and do not have the attribute of intelligent monitoring

[0003] In the existing technology, the application effect of dust removal and dust reduction measures in mining production operations is not good, the detection methods cannot be applied, the source of dust cannot be suppressed, the harsh environment is not suitable, and the number of manual operations and dangers are increased, which in turn aggravates equipment wear and pollution. The surrounding environment, threats to the physical and mental health of operators, and problems affecting the efficiency of iron ore production operations
