Mine Ventilation Airflow Testing Method and System Design
In order to solve the problem of coal mine ventilation fan airflow test,based on the airflow test method,we analyse the distribution of wind speed and the determination of the location of the wind measurement point,and design the ventilation fan airflow test system from the aspects of hardware design and software development.Taking the circular roadway of a mine as the test object,the relevant performance was tested through test simulation before application.The results show that the nonlinearity of the airflow test system is 1.18％at most,the return error is 0.72％at most,and the accuracy of the analogue input channel is 1.23％at most.The accuracy of the test system can meet the requirements of the performance test of the ventilator and achieve the accurate measurement of airflow.
