Abstract: This paper proposed a kind of coalbed methane drainage monitoring system based on intelligent control. The system
uses a programmable logic controller as the control center, and realizes continuous monitoring of underground bottom flow pressure
and temperature during coalbed methane extraction through monitoring sensors, and realizes adjustment of the operating speed of
the extraction equipment. The actual results show that the control system can control the underground bottom flow pressure variation
range within 0.4%, which effectively improves the control accuracy and speed of coalbed methane acquisition.

Key words: coalbed methane; underground bottom flow pressure; frequency conversion; intelligent control
