【正文】 ng some time interval。 this part is also in charge of the handling of traffic (monitoring, dispatch etc.) and other data connections (the localization data input, condition, renewal of vehicles, etc. ). Database management system (DBMS) The database management system mainly manages the database and increases, deletes, modifies and requires data from vehicles, drivers and operators。 those of the second point are (, ),latitude/longitude coordinate (, ).Their match is shown in Fig, 4. After obtaining the electronic map of Tab format, the electronic map is saved as Geoset by . 5) System debugging: Many parameters need to be rationalised in this system, given the real most important parameters are the demarcations of all the scanning regions in the open pit. At present there are five scanning regions, those of crushing stations I, II, III, the Nangou trough and the reserve have mainly adopted the method of scanning return paths made by many trucks to determine the areas. Besides, in some special terrain, scanning regions of irregular shapes can be determined by means of points and straight lines. Fig. 5 is the operation interface of the software system. Running the system The monitoring dispatch information system in the Sandaozhuang open pit has been used since March,2020. Some problems have arisen since then, such as drift and precision of GPS. These have been solved by optimization of the system software. After experiments with real scenes, the performance of the system is stable. It not only can track and localize trucks,play back historical paths, monitor the trucks automatically, but can also dispatch the trucks by voice and instructions, count the workload of trucks and shovels accurately. Fig. 6 shows some results of the data system of trucks. 5. Conclusions 1)Based on GIS/GPS/GPRS technologies, the monitoring dispatch information system of trucks and shovels in an open pit is a set of multidirectional,realtime, highly effective software system. The practical application indicates that the system improves labor productivity and the production scheduling efficiency in mines considerably and saves investment and transportation costs. 2) From GPS pinpoint data, the system can determine the delivery times of trucks and loading times of shovels. Its level of accuracy is 99%~100%. The system saves considerably on labor costs, reduces the effect of human factors on production scheduling and provides an accurate basis for matching ore plans. 3) The system is of great importance in the realization of automation in truck and information management in open pits, which definitely can be applied to other open pits.
