Research And Development Of Coal Mine Safety Monitoring System Based On GIS

With the advancement of Informatization in the field of coal mine safety production,safety production level of coal mine enterprises in China has been greatly improved.However,due to the weak foundation of Chinese mine safety production,major accidents has not been effectively curbed.In this article,after an analysis to the quo situation between safety monitoring system and GIS integration,a study on safety system for coal mine security are independent of each other,so as to the information cannot be Shared,and the gas prediction is not really combined with GIS technology is implemented.The main contents are as follows:1)Research on the video surveillance system cameras of visualization in GIS,using different resolutions camera to capture video,and do a research on video compression,using the bilinear interpolation method for image zooming,design packaged solution of the video data transmission with JRTPLIB library based on RTP protocol,and keep the video information used for playback.2)The basis for designing databases and real-time database to improve the efficiency of data query,simulating Real-time positioning of underground personnel by reading from the database in one day specified as the initial information in the view of personnel information,read the same compared with the record,a record under the position change shows staff had a mobile,loop read complete personnel information visualization refresh.3)Comparing the geology factors which influence gas content of 7 coal seam Qianjiaying mine,do research on Methods of establishment of regression model to predict gas,choose bigger relevance as a reference,and establishing gas content prediction model,using the regular grid method to generate gas content contour.The whole system includes real-time video monitoring,real-time data visualization personnel positioning,gas simulation,the gas historical data query,the gas content prediction,security assistance and related configuration,and other functions.The test results show that the software function has reached the design requirements and application conditions of research,which has a certain reference value to the Application of coal mine safety integrated system.
