Mine dust concentration measuring device and measuring method thereof

Abstract

The invention provides a mine dust concentration measuring device which comprises a sensitive element, a control circuit module and an upper computer. The sensitive element comprises inductive type metal electrodes, the control circuit module comprises a measuring circuit, a signal conditioning circuit, an A/D switching circuit and a microprocessor, the sensitive element generates micro electric charge signals on the metal electrodes, the micro electric charge signals are processed through the measuring circuit, the signal conditioning circuit, the A/D switching circuit and the microprocessor in real time and then are transmitted to the upper computer, and the upper computer carries out information preprocessing and feature extraction, sets up a soft measurement model, and then outputs dust concentration measuring signals. The invention further provides a dust concentration measuring method. The mine dust concentration measuring device and the measuring method thereof have the advantages that the defects that measuring errors are large, influences of humidity are obvious, the service life is short and maintenance is inconvenient in an existing mine dust concentration measuring method are overcome effectively, accurate measurement data for coal mine improvement are provided, the borehole operation environment is improved, and the physical health of workers and the safety production of coal mines are protected.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to a mine dust concentration measurement device and a measurement method thereof. Background technique [0002] Dust is everywhere, polluting the environment and endangering human health. Especially in coal mines, dust is more harmful. It will not only cause pneumoconiosis to miners, but also cause gas explosions. Therefore, it is necessary to detect the dust concentration accurately and quickly. At present, the common method to quickly measure the concentration of mine dust at home and abroad is the light scattering method, but this kind of method has the disadvantages of large measurement error, obvious influence of humidity, short service life, and inconvenient maintenance. Therefore, in view of the current situation of the above methods, a new device and method for measuring the concentration of mine dust is proposed, which is of great significance for improving the ...
