Problems solved by technology

[0004] However, the cause of the dust explosion is often the dust concentration is too high at a certain moment, and when the average dust concentration is used to measure the on-site dust concentration, the real-time performance of the average dust concentration data obtained is poor, even if it is obtained for a period of time The average dust concentration in the area does not exceed the standard, and it is very likely that th

Embodiment 1

[0033] In the coal mine dust monitoring system disclosed in Embodiment 1, the light absorption type concentration sensor is a sensor that has undergone error correction processing in advance, so that the accuracy of the measured dust concentration data is higher; in addition, the light absorption type concentration sensor in this embodiment is Developed based on Lambert-Beer's law, in the case of low dust concentration on site, the optical absorption type concentration sensor developed based on Lambert-Beer's law can also maintain a high measurement accuracy; secondly, the sampling period of the optical absorption type concentration sensor For the self-adjusting sampling period, in different dust concentration environments, the light absorption concentration sensor can adopt an appropriate sampling period, which reduces unnecessary power consumption and is conducive to improving the working life of the sensor; further, the on-site monitoring module It also includes an infrared ...

Abstract

The invention discloses a coal mine dust monitoring system and method. The system comprises a light absorption type concentration sensor, a data processing system and a control system, wherein the light absorption type concentration sensor is used for collecting real-time dust concentration data, when the real-time dust concentration data is an abnormal value, the data processing system generates warning eliminating signals, when the real-time dust concentration data is changed from an abnormal value to a normal value, the data processing system generates warning elimination signals, and the control system is used for controlling a spraying dust reducing unit to start or stop the spraying processing. In the system disclosed by the embodiment of the invention, the collected dust concentration data is real-time dust concentration data, the condition that the dust explosion can be caused since the real-time performance of the dust concentration data is poor in the prior art is avoided, and the dust explosion possibility is reduced; in addition, the control system can control the spraying dust reducing unit to stop the spraying processing, the condition that the spraying device is in the spraying state for a long time due to the personnel negligence in the prior art is avoided, and the utilization rate of water resources is improved.

Description

technical field [0001] The invention relates to the technical field of dust concentration monitoring, in particular to a coal mine dust monitoring system and method. Background technique [0002] At present, the coal production process often produces a large amount of dust, and excessive dust concentration can easily cause explosions at the production site, resulting in serious loss of life and property. [0003] Nowadays, domestic coal mine enterprises generally judge whether the dust concentration on the job site exceeds the standard by measuring the average dust concentration within a period of time. When the average dust concentration exceeds the standard, the spraying device is activated by manual control to achieve the purpose of dust reduction. [0004] However, the cause of the dust explosion is often the dust concentration is too high at a certain moment, and when the average dust concentration is used to measure the on-site dust concentration, the real-time perform...
