Example Embodiment

[0018] With reference to the accompanying drawings, an automatic detection and control system for mine dust concentration and environmental parameters includes an upper computer 1 located on the well and at least one downhole control unit 2. The number of downhole control units 2 can be freely configured according to different conditions of downhole operation areas (points), and the layout area where one downhole control unit is located can be used as a measurement area (point). This example shows three downhole control units. Take a downhole control unit as an example to illustrate it: it includes a downhole sensor group, a downhole PLC controller 201 and downhole external equipment; the downhole sensor group includes a dust concentration sensor 202, a temperature and humidity sensor 203, a flow sensor 204, and infrared The sensor 205, in which the dust concentration sensor 202 is used to measure the dust concentration of the environment, can be installed above the mine tunnel...

Abstract

The invention discloses a mine dust concentration and environmental parameter automatic detection and control system which comprises an upper computer and at least one downhole control unit, and the downhole control unit comprises a downhole sensor group, a downhole PLC controller and a downhole peripheral device; the downhole sensor group comprises a dust concentration sensor, a temperature and humidity sensor, a flow sensor and an infrared sensor; the downhole PLC controller is used for carrying out analysis, screening and contrast on a received data signal sent from the sensor group, then forming a control signal and further outputting to the downhole peripheral device; the downhole peripheral device comprises a spray system and an alarm device; and the upper computer and the downhole PLC controller carry out data signal transmission through a communication module, thereby being capable of carrying out on-line real-time monitoring. The system can lead dust concentration, humidity, temperature and other environmental parameters of related points of a downhole operation space to be measured by the sensor group in a real-time manner, and further adopt the corresponding control measures, such as alarm, spray dedusting, cooling and the like.

Description

technical field [0001] The invention relates to the field of mine safety detection and control, and more specifically relates to an automatic detection and control system of mine dust concentration and environmental parameters. Background technique [0002] Coal mine dust refers to the general term for fine solid particles such as coal and rocks produced in the production process of coal mines. Dust may be generated in various production links in underground coal mines, such as drilling, explosive blasting, roadheader excavation, coal cutting by shearer, coal loading, coal mining support and caving, roadway support, loading, transportation, reloading, unloading and lifting, etc. Dust hazards can not only cause coal miners to suffer from pneumoconiosis, but also easily cause explosions and cause major safety accidents. According to statistics, by 2009, 89.37% of the 639,000 pneumoconiosis cases in the country were miners' pneumoconiosis, and the number of cases was increasin...
