英文原文 Monitoring dispatch information system of trucks and shovels in an open pit based on GIS/GPS/GPRS Abstract Using GIS, GPS and GPRS, an intelligent monitoring and dispatch system of trucks and shovels in an open pit has been designed and developed. The system can monitor and dispatch open-pit trucks and shovels and play back their historical paths. An intelligent data algorithm is proposed in a practical applicat- ion. The algorithm can count the times of deliveries of trucks and loadings of shovels. Experiments on real scenes show that the performance of this system is stable and can satisfy production standards in open pits. Keywords GIS; GPS; GPRS; dispatch; data processing; open pit 1 . Introduction To date the development of truck monitoring dinpatch systems in the world, such as the DISPATCH monitoring system of the American Module Company has reached a highly mature level and is almost univernal. It has developed into a decision-making platform by management as a control system in multi-direction- al mining production, called Intellimine. In 1998, DISPATCH was introduced into the Dexing Copper Mine in Jiangxi, China. It has clearly enhanced the service efficiency of equipment, improved the management level in the open pits and obtained better overall benefits. In 2003, the Dandong Dong-fang Measurement and Control Technology Co. Ltd.,together with the Qidashan Iron Mine have developed a dispatch management system for trucks in open pits. The system has become indispensable to daily production management. It must be emphatically pointed out that the greatest disadvantage of these systems is that they cost too much. The major cause is that an independent communication network needs to be established and maintained by every open pit. Many mines can not afford such a system. However, using GIS/GPS/GPRS technologies, it is not necessary to establish independent communication networks in every open pit. The network can be maintained and upgraded by a thir
