采空区瓦斯抽采实验监控系统的设计

Design of Monitoring and Control System of Goaf Gas Extraction Experiment

为了实时掌握采空区瓦斯抽采实验系统的运行状况,设计了一套采空区瓦斯抽采实验监控系统。该监控系统采用EDA9017和EDA9150采集巷道瓦斯流量和浓度、风流静压力、风速值和风机的运行状态信息,并将采集的数据通过RS485总线传入PC机,使操作者通过监控界面即可了解整个采空区瓦斯抽采实验系统的运行状况。实际应用验证了该监控系统的有效性、稳定性和可靠性。

In order to real-timely get running state information of experiment system of gas extraction in goal, a monitoring and control system of goal 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 goal through monitoring and control interface. The actual application verified validity, stability and reliability of the system.
