Research Of Mine Maps Processing Based On SVG Standard

Coal industry as a pillar industry of national economy, security of production and protection of the lives and safety of miners is an eternal theme, the distribution and the specific location of Underground staff and other important data can not be reached in time Inoue Control Center, that is the causes of mine accidents and a very low efficiency of the rescue. Based on this status quo, there are a number of companies specializing in only the safety monitoring system for coal mine development, but to market the use of these monitoring systems are raster graphics into the format as mine plans, mine plans can not meet the non-polar scaling, elements of inquiry, such as the actual needs of real-time modifications.For the lower power of Coal Mine Safety Monitoring System in Underground geographic information collection and processing, the paper design of a Mine Maps processing systems based on SVG technology,System is based on the SVG specification, using vector Web development technologies such as XML, JavaScript, the DOM analysis of SVG, including Web display, query, editing and format conversion, which is the urgent need to introduce mining map processing function in practice. Mine Maps processing system can be integrated into a number of mine safety monitoring system, such as security monitoring, emergency mine rescue, mine location, To provide reliable geographical information resources. the system avoids solid and dwells on void, get rid of the inadequate of using grid graphics as Mine Maps format in the traditional monitoring system, The introduction of vector graphics format to display and process Mine Maps,made the displaying and processing of Mine Maps more accurate, reliable, practical and efficient.In addition, this paper introduce the thought of "LOD" hierarchical display in the long-range displaying of mine maps, to reduce the numbers of drawing the mineral elements, That is a reduction of the mine map information of the actual transmission and rendering. this paper introduce the use of "relevant area" search algorithm,which increases the cost of space, creats index for each elements of mine maps using dynamic arrays, reduces the time for mine mapping Significantly, and improve the efficiency of mine map shows further, by analyzing the transmission vector encoding of Mine map, proposed improvements to the LZW algorithm, making mining maps in the network data transmission rate is further. Thesis research work done in the practical application of values as the criteria for integration in the coal mine safety monitoring system to deal with mine shows the application development and provides a new reference.
