The system uses GIS technology for the development of digital mine map database and GPS for vehicle positioning. The system consists of five modules: position module incorporated GPS and dead reckoning (DR); a map database structure for displaying and guidance purposes; a routing module based on the map database is able to give out the best route for the vehicles; map matching and route guidance module put the vehicle position to its exact location on the road despite of errors in positioning and map data; and the client-server module allows client exchange information between driver and control centre. The system can be operated in client-server level in which users can request routing and guidance with devices such as hand phone and PDA by communicating their current positions to the server or runs in autonomous mode when users cannot reach the server.展开更多

Each customer has its special requirements on GIS system when he installs it. We discuss a common structure of our GPS/GIS implementation, and present a case study on bulk concrete trucks management for bulk concrete producers. With GPS/GIS system, bulk concrete producers can improve their performance in scheduling and management.展开更多
