Abstract
In order to real-timely get running state information of experiment system of gas extraction in goaf, a monitoring and control system of goaf gas extraction experiment was designed. The system uses EDA9017 and EDA9150 to collect gas flow, gas concentration, static pressure of airflow, value of air velocity and running state information of fan, and sends the collected data to PC through RS485 bus to make operator know running state of the experiment system of gas extration in whole goaf through monitoring and control interface. The actual application verified validity, stability and reliability of the system.
