The system can monitor and dispatch openpit 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 decisionmaking platform by management as a control system in multidirection 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 2020, the Dandong Dongfang 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 bee 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 munication work 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 munication works in every open pit. The work can be maintained and upgraded by a third party (., China Mobile Communication Co. Ltd). This can reduce costs considerably and provides a good platform for medium and small open pit mines to establish a fast, highly tive, and practical ground transportation system. Such a system is very important in enhancing labor productivity, reduce mining costs and promote mining technologies to an unprecedented level in open pits. 2 . GIS/GPS/GPRS GIS The Geographic Information System (GIS) is one kind of puter system gathering, storing, managing,analyzing, demonstrating and applying geographic information. It is a general technology that can analyze and process enormous amounts of geographic data. It takes a geographic space database as its foundat ion, uses a geographic model analysis method to provide many kinds of spatial and dynamic geographic information and serves as a geographic research and decisionmaking tool. It has some basic functions such as electronic mapping, spatial data management and spatial information analysis. GIS has been applied in many fields to establish all kinds of spatial databases and decision support systems,each with different criteria and provide answers to many different formal spatial inquiries, spatial analyses and assistance plans and decisionmaking func tions. To date, GIS has pits. The task been gradually applied in open of a monitoring dispatch information system of trucks and shovels in open pits is to track, monitor and manage production equipment,which depends largely on geographic spatial information. Therefore GIS plays an important role in visual supervisory systems of trucks, realtime dynamic management and assistance in decision analysis. GPS The Global Positioning System (GPS) is a satellitebased navigation system made up of a work of 24 satellites placed in orbit. Their ground stations are managed by the . Department of Defense. A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position (latitude and longitude) and track movements. With four or more satellites in view, the receiver can determine the 3D position of trucks (latitude, longitude and elevation). Once the position of the truck has been dete rmined, the GPS unit ca
