The Research And Application Of WebGIS In Coal Mine Safety Monitoring

Currently in China coal mine safety monitoring field, many coal mines safety and production monitoring equipment is relatively backward, and the monitoring system is simple, function is not rich enough, and the user experience remains to be improved, most of the monitoring system is based on the information displayed in tabular form, which for operator control of the global demands made larger. The GIS system can be provided on the basis of the map user a good interactive function, so the GIS and combining existing security monitoring system is the main content of this project.This article first briefly introduces the current WebGIS coal mine safety monitoring system and the status quo, and discuss aspects of the relevant comparison WebGIS technology, then according to the actual situation analysis of the project requirements, according to the project requirements and on WebGIS related technology research, put forward the corresponding solution. Among them, for the overall system design using common on B/S three-tier architecture model. Where the client for loading and GIS data integration platform compatibility is the focus of this article content. For the client, focusing on the design of the business data and GIS data merging, and focus on the design of the request for data interactively, in order to ensure the compatibility of different GIS platform; in order to meet the relevant requirements, the design of the part of the relevant data model, in order to reduce development difficulty, the existing ArcGIS API based on the design and implementation of the relevant key GIS functions.To meet the needs of customers at different levels, were selected commercial systems and open source platform ArcGIS GIS server GeoServer to build the system, with no dependence on the database design to ensure the applicability of different production environments. In order to ensure the integration with existing systems, to take a separate GIS data with business data model, data association only achieved by ID, to achieve the present system GIS extensions, and minimize the impact of its previous function.Better overall system design of the proposed project implementation needs to ensure that the integration with existing systems. Taking fully into account the future expansion of system functions.
