Mine dust concentration and environmental parameter automatic detection and control system

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...

Problems solved by technology

According to relevant information, some foreign developed countries (such as British Mitchell company, Germany Tyndall, etc.) have developed a dust concentration computer detection system, which can realize continuous automatic detection, but these systems do not consider environmental factors, only a single Measuring the dust concentration, and it is expensive and inconvenient to maintain, it is not suitable for the actual field of coal mines in my country
