Single-point measurement and control device and method for average wind speed of mine roadway

Abstract

The embodiment of the invention discloses a single-point measurement and control device and method for the average wind speed of a mine laneway, and the method comprises the steps of determining a measurement and control point in the roadway, and building a wind speed measurement system at the measurement and control point; setting the front and rear areas of the measurement and control point as measurement and control areas, and judging whether the current state of the measurement and control areas is suitable for wind speed measurement or not; according to the judgment result, operating thewind speed measurement system to measure the single-point wind speed, so that the influence of mining operation and roadway passage on the wind speed measurement can be avoided, it is ensured that themeasured average wind speed is not interfered by temporary factors, and the detection accuracy is improved. By converting the single-point wind speed measurement result into an average wind speed, and comparing the measured average wind speed with the average wind speed set by the system, if the measured average wind speed is within the average wind speed allowable range, the wind speed of the fan is not adjusted, and if the measured average wind speed is not within the average wind speed allowable range, an adjusting signal is transmitted to the fan control system, so that the fan can be adjusted according to the wind speed in the roadway, and the wind speed in the roadway is controlled to meet the production requirements.

Description

technical field [0001] The embodiment of the invention belongs to the technical field of mine ventilation, and specifically relates to a single-point measurement and control device and method for the average wind speed of a mine roadway. Background technique [0002] Mine ventilation is an important part of mining operations. The measurement of the average wind speed in the tunnel is the basis for ensuring the reliable operation of the mine ventilation system and an important work content of mine ventilation management; by measuring the average wind speed, the ventilation status in the tunnel can be grasped in a timely and effective manner; The accuracy and real-time performance of average wind speed measurement has important practical significance for mine safety. [0003] The traditional roadway wind speed measurement often adopts the line method (that is, the wind meter is used to move at a constant speed on the roadway section according to a certain line, and the average...
