Abstract：Because gas extraction data analysis method is simple and the automation level is not high,a new intelligent and visual system is designed that not only can analyze methane concentrations,the rate of flow,and the pressure and gas temperature of a pipeline,but also automatically actualize data classification,data statistics,graph display,and information prompt. The system has the function of query,print,statements,and warning; also it can dynamically display the extraction situation of pre pumping section,provide accuracy information in order to know gas threaten,and ensure safety production.
