Abstract: In order to solve the manual inspection data can not be real-time upload existing gas inspection in the process of management, the results of data processing can not be timely feedback to the site and other issues, relying on the handheld terminal, wireless transmission network, information terminal hardware and software, through the intelligent control of gas inspection technology research, design and development of the inspection and control system of coal mine gas dynamic system.The patrol recorder through the credit card and take with the multi parameters gas detector automatically records the combination of real-time detection and recording.At the same time, the related information is transmitted to the ground data center in time, and the gas patrol system is used for analysis, storage and management.According to the analysis results, corresponding reports are generated, and early warning and information release for abnormal situations are carried out to ensure the symmetry of the safety information on the ground and underground.The results show that after the implementation of the system, it is effective to eliminate hidden dangers such as post job loss, missed detection and misreporting, which ensure the authenticity of the test data and standardize the process of safety detection and control.
