| The integration of the multi-source information is an important subject of the safety production monitoring of mining enterprises at present. The integration technology of information platform is especially studied based on multi-source, multi-type data and multimedia underground. A universal information integrated platform for mine with data stream management, spatial data management and multimedia management is designed in this paper.The model of data stream and the definition of continuous query language are proposed based on the interrelated technology of data stream and data stream management. Data stream management subsystem of the integrated platform is designed to manage the monitoring information of mine underground. The integration of MIS and GIS is studied. The design of spatial database and geographical information management subsystem is presented based on integration of MIS and GIS, and it realizes the integration of geographical information and attribute information. Multimedia technology is utilized in integrated platform, and also the design of multimedia secondary database and multimedia management subsystem is proposed. The integration of multimedia data and spatial data is implemented by using relation database.The integration of MIS, GIS, DSMS and multimedia in the information integrated platform for mine realizes the management-control incorporation of safety production underground, and this greatly solves the information isolated island problems of different mine subsystems .The integrated information system satisfies the requirements of mining safety. This platform can be used in kinds of underground operation enterprises and underground facilities for the aim of management-control incorporation, and it has the vast prospect. |
