Abstract
To improve the accuracy and reduce the disturbance during the monitoring, the index system and the mathematic model of optimal wind speed sensors’ location are established using the variable fuzzy theory. Then the adjustment analysis of redundant wind speed sensor measurement and the standard deviation filter method are put forward. Then, the dynamic monitoring technology in mine ventilation network is formed and the automatic monitoring system of air quantity in mine ventilation network is established. The application in a complex ventilation network shows that, this method only needs 10 wind speed sensors (7 must install points and 3 redundant install points) to obtain the air quantity of 19 branches. And it can achieve the dynamic monitoring in the underground roadway, which provides an important basic data for management decisions in mine ventilation network.
