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,2021. 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.

Database management system (DBMS) The database management system mainly manages the database and increases, deletes, modifies and requires data from vehicles, drivers and operators。 the statistical results can be transformed to report forms by class, month and season, according to need of the user. 2) Count of loading by shovels: count accurately the loading time during some time interval of each shovel。the red light of the terminal will clearly indicate that instructions are given and will ring. 7) Terminal information feedback: the terminal carried by trucks can upload the prefabricated fixed information on the operation surface of the terminal and return feedback to the monitoring center which can deal with the information in a timely fashion. GPS data processing client (GDPC) The function of the GPS data processing is to record the times delivered by trucks and the times loaded by shovels. The concrete function is as follows: 1) Count of delivery by truck: count accurately the delivery times of each truck from shovels to crushing stations during some time interval。 do not display trucks or shovels according to given mands. 3) Playback of historical paths: play back the travel path of any truck at some time on the electronic map. 4) Inquiry about the location of a truck: inquire current position, speed, condition and driver of any truck at any moment. 5) Instruction dispatch: the monitoring center can send out dispatch instructions as text。 pute the area of a random polygon。 display coordinates of a random point on the map。 data processing。 GPRS。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 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。 dispatch。 open pit 1 .
