Mine GIS Technology Research Based On Rescue Robot

Our country coal production accident frequently, the significant malignant accident leads the danger rising, rescuing difficult. In order to carry out relief work in science in a timely manner, it's necessary to study a way to replace human beings to get the scene of the accident scene, with independent movement, intelligent control of the underground robot new method for rescue.According to the established underground-GIS system that can identify the real-time analysis of science and rescue routes, guiding mine rescue team members carry out emergency rescue, to avoid or reduce secondary injury, thereby enhancing the rescue of China's coal mine safety accident level. The thesis studies mainly from several the following aspects:(1) Mine rescue robot's positioning and tracking analystAs the mine rescue robot can not receive GPS satellite signals in an underground mine, it can not use satellite positioning technology to mine rescue. However, you can use mine rescue robot localization algorithm based on distance, build robot navigation coordinates, through the X, Y, Z coordinate values to describe the location of the robot, combined with the method of artificial landmark positioning to correct error.In the mine accident, in order to be able to scene of the accident environment in real-time monitoring and information query, it need to real-time monitoring and tracking. The GIS tracking analyst module can be simulated mine rescue robot in the movement of the mines to achieve the time event data input, display and analysis, the visualization of the robot positioning navigation, running status and interactive playback.(2) Construction of roadway geometric network model and rescue shortest path analysisGIS network analysis techniques will be applied to the mine tunnel analysis, it is a new subject, which for the response to under mine emergency situation has an important significance. When a sudden shaft of water, gas and coal dust explosions, cave, fire, equipment damage and other disasters happen, through the network analysis can quickly calculate the shortest path to help the rescue robot achieve proper navigation, in order to minimize casualties underground.(3) Three-dimensional visualization of underground tunnelTraditional paper mine maps and GIS established under the mine plans are based on two-dimensional plane, while the robot to successfully achieve the real-time positioning and autonomous navigation, we must study the two-dimensional data three-dimensional visualization. Use SketchUp to establish three-dimensional model, take advantage of Scene-Control provided by ArcGIS Engine as the three-dimensional display platform; Combine with Visual C #. Net to achieve three-dimensional visualization of the tunnel; Simulate and display the working status and environment of mine rescue robots.
