n ore pass and electric lootives. The monitoring dispatch information system of trucks and shovels in this open pit consists mainly of terminals and monitoring dispatch software. Software constitution and its function GIS monitoring dispatch client (GMDC) The GIS monitoring dispatch client can be installed in the monitoring center to manage, dispatch and monitor trucks and shovels. Its functions are as follows: 1) Map operation: zoom in, zoom out, roam and display lamination maps。 display coordinates of a random point on the map。 pute the distance of two random points。 pute the area of a random polygon。 inquire about the geographic target information etc. 2) Vehicles display: display the several trucks or shovels differently, ., different colors and different marks。 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。 the terminal carried by trucks will clearly indicate and display, with a red light, the dispatch instructions on the terminal. 6) Pronunciation dispatch: the monitoring center can call any terminal carried by vehicles for dispatch。 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。 the interval can be set by users。 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。 other functions are the same as in 1). GPS localization data processing server (GLDP) The function of the GPS processing server is mainly to filter, extract and process the localization data of trucks and shovels in order to enhance the level of accuracy and statistical efficiency. Data munication control server (DCCS) The munication control server mainly gathers,transmits and routes the data through the TCP/IP and analyzes the munication protocol and the distribution of data。 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。 it regularly backs up the data and then deletes it. System application deployment The process of the entire system deployment is as follows: 1)Early preparation: the terrain of the open pit is plex, the munication signals are bad and there are many blind signal zones. A munication base seat and a repeater were built by China measures have solved the signal problem. 2) Terminal installation: the type of terminals is a HQ60006T10 provided by the Shenzhen Huaqiang Holdings Ltd. GPS terminals had been installed in 75 trucks and shovels during an earlier period. The terminal consist mainly of a mainframe, a GPS antenna,a GPRS antenna, a display, a red indicating lamp, earphones, a sound box as well as a microphone. After installation, the terminal needed debugging. It mainly sets the parameters of the main frame (number,IP, port, etc)using an operation handle. 3) Software deployment: there are five subsystems in the project. A schematic deployment structure is drawn in Fig.。
