Roadway wind speed remote unmanned automatic measuring and monitoring system and method

Abstract

The invention relates to a roadway wind speed remote unmanned automatic measuring and monitoring system and method. The measuring and monitoring system comprises a ground monitoring host, an underground network switch, an underground centralized display and data transmission device, a PLC, a first longitudinal rod, a second longitudinal rod, a transverse rod, a first driving device, a second driving device, a third driving device, a first longitudinal sliding block, a second longitudinal sliding block, a transverse sliding block and a wind speed sensor. Through the equipment and the control system, the wind speed sensor moves on a roadway section according to a set track, measures the roadway wind speed in real time, calculates the average roadway wind speed, uploads measurement data to the ground monitoring host after measurement is completed, and returns to a monitoring state. The system can replace the heavy underground work of wind measurement personnel, guarantees the accuracy ofmeasurement data, is integrated with wind speed monitoring, and facilitates the less-man, unmanned and intelligent development of a coal mine.

Description

technical field [0001] The invention belongs to the field of wind speed measurement and monitoring in coal mine tunnels, and relates to a remote unmanned automatic measurement and monitoring system and method for roadway wind speeds. Background technique [0002] Mine ventilation is the "blood circulation system" of coal mines, which provides fresh air for the discharge of toxic and harmful gases underground and the occupational health of miners. Whether the air volume in the roadway is sufficient and stable is the key to safe production in coal mines. Therefore, wind speed measurement and monitoring in coal mine roadway is an important work for mine safety management. [0003] In terms of wind speed measurement, the coal mine conducts manual wind speed measurement of the main locations of the whole mine every ten days. This method has the following problems: (1) the coal mine needs to be equipped with a team of wind measuring personnel with dozens or even dozens of people; ...

Problems solved by technology

[0003] In terms of wind speed measurement, the coal mine conducts manual wind speed measurement of the main locations of the whole mine every ten days. This method has the following problems: (1) The coal mine needs to be equipped with a team of wind measuring personnel with dozens or even dozens of people; (2) The experience of different wind measuring personnel is different, the accuracy of the measurement data varies greatly, and there is no evaluation standard; (3) The underground wind measuring sites of coal mines cover a large area, the distance is long, the environment is harsh, and the wind measuring work is labor-intensive underground; (4) ) The traditional manual working method cannot meet the requirements of less people, unmanned and intelligent coal mines

[0004] In terms of wind speed monitoring, coal mines install wind speed sensors on the roof of roadways in main underground locations, and collect wind speed data in real time and upload them to the ground monitoring system. There are still several problems in the installation and monitoring of wind speed sensors: (1) Monitoring of wind speed sensors It is a single-point monitoring, and the installation position is generally 400-500mm away from the roof according to experience, so it is difficult to ensure that it is exactly at the position of the average wind speed of the roadway; (2) The underground dust concentration is high and the humidity is high, which causes changes in sensor accuracy, coupled with changes in underground production Changes in wind speed require frequent adjustment of the position of the wind speed sensor, but there is no basis for sensor position adjustment

These two problems lead to a large difference between the monitoring data and the actual required average wind speed, and it is impossible to accurately grasp the actual air volume of the roadway

[0005] At present, there is no automatic technical equipment that can replace manual wind measurement and monitor and correct wind speed sensors based on the measurement results.
