7、ne. 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

8、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.</p><p>　　The sys

9、tem 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 communic

10、ation 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 netw

11、orks in every open pit. The network can be maintaine</p><p>　　2 . GIS/GPS/GPRS</p><p><b>　　2.1 GIS</b></p><p>　　The Geographic Information System (GIS) is one kind of c

12、omputer system gathering, storing, managing,analyzing, demonstrating and applying geographic</p><p>　　information. It is a general technology that can analyze and process enormous </p><p>　　amo

13、unts of geographic data. It takes a geographic space database as its foundat-</p><p>　　ion, uses a geographic model analysis method to provide many kinds of spatial</p><p>　　and dynamic geograph

14、ic information and serves as a geographic research and</p><p>　　decision-making tool. It has some basic functions such as electronic mapping, spatial data management and spatial information analysis. GIS has

15、 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 assi

16、stance plans and decision-making func-</p><p><b>　　tions.</b></p><p>　　To date, GIS has pits. The task been gradually applied in open of a monitoring dispatch information system of t

17、rucks 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,

18、real-time dynamic management and assistance in decision analysis.</p><p><b>　　2.2 GPS</b></p><p>　　The Global Positioning System (GPS) is a satellite-based navigation system made up

19、of a network of 24 satellites placed in orbit. Their ground stations are</p><p>　　managed by the U.S. Department of Defense.</p><p>　　A GPS receiver must be locked on to the signal of at least t

20、hree satellites to calculate a 2D position (latitude and longitude) and track movements. With four</p><p>　　or more satellites in view, the receiver can determine the 3D position of trucks (latitude, longitu

21、de and elevation). Once the position of the truck has been dete-</p><p>　　rmined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, suprise and sunset time and more.

22、 GPS works in all weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or establishment charges to use GPS.</p><p>　　To date, as GPS units are becoming smaller and less e

23、xpensive, there are an expanding number of applications for GPS in open pits. With GPS, the monitor-</p><p>　　ing dispatch information system of trucks and shovels in open pits provides cua-</p><p

24、>　　ccurate position (latitude and longitude), speed, bearing, time, track and more basic information of trucks and shovels.</p><p><b>　　2.3 GPRS</b></p><p>　　The General Packet R

25、adio Service (GPRS) is one of GSMPhase2+ standard realization contents and can provide fast data transmission speed. Theoretically,</p><p>　　this service is ten times faster than the current Circuit Switched

26、 Data services on GSM networks. GPRS uses the same frequency range,bandwidth, sharpedged structure wireless modulation standard,frequency-hopping rule and TDMA frame structure as GSM.</p><p>　　The monitoring

27、 dispatch information system of trucks and shovels in open pits largely uses the advantages of GPRS such as faster speed and instant connections as the need arises and charging by amount of data. It can provide realt- i

28、me wire-</p><p>　　less transmission and is very quick without a dial-up modem connection to GPS equipment for position information. That is very important because GPS position information has room for only a

29、 small amount of data and needs to be transmitted frequently. So this system can make good use of GPRS to transmit GPS position information.</p><p>　　3. Principle of monitoring dispatch system of trucks and

30、shovels</p><p>　　3.1 Monitoring dispatch system of trucks and shovels</p><p>　　The monitoring dispatch system is composed of mobile terminals carried by vehicles, a communication network and a m

31、onitoring center, as shown in Fig.1 .</p><p>　　In this system the mobile terminals receive GPS signals and then calculate the latitude, longitude, angle, elevation and speed of the vehicles. The expansion in

32、terfaces of mobile terminals can also meet many examination and control lines to obtain the information from the vehicles. Each kind of information is transm-</p><p>　　itted to the monitoring center through

33、GPRS and the Internet. GPRS, as a teleco-</p><p>　　mmunications network between the mobile terminals and monitoring center, mainly transmits the information on position and condition of the vehicle and infor

34、mation in case of an alarm, to the monitoring center, which in turn transmits dispatch and control commands to the vehides.</p><p>　　In the monitoring center, the communication server, the database server an

35、d the console are connected by a 100M local area network. The monitoring center under control of the system software system receives and processes all kinds of information coming from the controlled vehicles. The positio

36、n, paths and other information of the vehicles are displayed at LED multimedia monitors and electronic maps in the monitoring center and from these the vehicles can be monitored and dispatched. Besides, the</p>&l

37、t;p>　　3.2 Data processing system of trucks and shovels</p><p>　　The data processing system of trucks and shovels at first locates the real-time positions of trucks through GPS and GPRS and then determines

38、 the loading mine position A (longitude, latitude) through a terminal on the shovel and the unloading mine position B (longitude, latitude) through GPS equipment. The rea-</p><p>　　ltime location of truck C

39、(longitude, latitude) can be determined according to a terminal installed in the truck,as shown in Fig. 2.</p><p>　　4.Monitoring dispatch information system of trucks and shovels in Sandaozhuang open pit<

40、/p><p>　　The Sandaozhuang open pit is part of the Luoyang Luanchuan Molybdenum Industry Group Inc. Its output is 1O million tons. Its length is 2350 m, its width 1350 m and its mining elevation is between 1114

41、 and 1630.8 m. The height of mining is 516.8 m and the bench height 12 m. Rotary drilling machines, shovels and trucks are used in this mining process.The transportation system consists of a number of trucks, a crushing

42、station, an ore pass and electric locomotives. The monitoring dispatch informat</p><p>　　4.1 Software constitution and its function</p><p>　　4.1.1 GIS monitoring dispatch client (GMDC)</p>

43、;<p>　　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:</p><p>　　1) Map operation: zoom in

44、, zoom out, roam and display lamination maps; display coordinates of a random point on the map; compute the distance of two random points; compute the area of a random polygon; inquire about the geographic target informa

45、tion etc.</p><p>　　2) Vehicles display: display the several trucks or shovels differently, e.g., different colors and different marks; do not display trucks or shovels according to</p><p>　　give

46、n commands.</p><p>　　3) Playback of historical paths: play back the travel path of any truck at some time on the electronic map.</p><p>　　4) Inquiry about the location of a truck: inquire curren

47、t position, speed, condition and driver of any truck at any moment.</p><p>　　5) Instruction dispatch: the monitoring center can send out dispatch instructions as text; the terminal carried by trucks will cle

48、arly indicate and display, with a red light, the dispatch instructions on the terminal.</p><p>　　6) Pronunciation dispatch: the monitoring center can call any terminal carried by vehicles for dispatch;the re

49、d light of the terminal will clearly indicate that</p><p>　　instructions are given and will ring.</p><p>　　7) Terminal information feedback: the terminal carried by trucks can upload the prefabr

50、icated fixed information on the operation surface of the terminal and</p><p>　　return feedback to the monitoring center which can deal with the information in a timely fashion.</p><p>　　4.1.2 G

51、PS data processing client (GDPC)</p><p>　　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:</p>&

52、lt;p>　　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 tra

53、nsformed to report forms by class, month and season, according to need of the user.</p><p>　　2) Count of loading by shovels: count accurately the loading time during some time interval of each shovel; other

54、functions are the same as in 1). 4.1.3 GPS localization data processing server (GLDP)</p><p>　　The function of the GPS processing server is mainly to filter, extract and process the localization data o

55、f trucks and shovels in order to enhance the level of accuracy and statistical efficiency.</p><p>　　4.1.4 Data communication control server (DCCS)</p><p>　　The communication control server main

56、ly gathers,transmits and routes the data through the TCP/IP and analyzes the communication protocol and the distribution of data; this part is also in charge of the handling of traffic (monitoring, dispatch etc.) and oth

57、er data connections (the localization data input, condition, renewal of vehicles, etc. ).</p><p>　　4.1.5 Database management system (DBMS)</p><p>　　The database management system mainly manages

58、the database and increases, deletes, modifies and requires data from vehicles, drivers and operators; it regularly backs up the data and then deletes it.</p><p>　　4.2 System application deployment</p>

59、<p>　　The process of the entire system deployment is as follows:</p><p>　　1)Early preparation: the terrain of the open pit is complex, the communication signals are bad and there are many blind signal

60、zones. A communication base seat and a repeater were built by China Mobile.These measures have solved the signal problem.</p><p>　　2) Terminal installation: the type of terminals is a HQ60006-T10 provided by

61、 the Shenzhen Huaqiang Holdings Ltd. GPS terminals had been installed in 75</p><p>　　trucks and shovels during an earlier period. The terminal consist mainly of a mainframe, a GPS antenna,a GPRS antenna, a d

62、isplay, a red indicating lamp,</p><p>　　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, et

63、c)using an operation handle.</p><p>　　3) Software deployment: there are five sub-systems in the project. A schematic deployment structure is drawn in Fig. 3. The data communication control system is deployed

64、 in the web server of the company; the localization data processing system and the database management server are deployed in the database server of the company; the data processing client and the monitoring client of tr

65、ucks and shovels are deployed in the monitoring center of the open pit.</p><p>　　4) Coordinate registration: in first instance, the present topographic map of the open pit should be renewed. Under AutoCAD20

66、06 we can transform it from DWG to DXF format. Then we can match the present DXF topographic map to the coordinates. Establish a longitude/latitude (wgs84) coordinate system and select a couple of coordinates: the geodet

67、ic coordinates of the first point are: (6755.3044, 4850.7990),latitude/longitude coordinates (111.506202, 33.91905);</p><p>　　those of the second point are (6459.1221, 5482.2094),latitude/longitude coordinat

68、e (111.50295, 33.92468).Their match is shown in Fig, 4. After obtaining the electronic map of Tab format, the electronic map is saved as Geoset by MapX5.0.</p><p>　　5) System debugging: Many parameters need

69、to be rationalised in this system, given the real situation.The 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 st

70、ations I, II, III, the Nangou trough and the reserve mine.They 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 irr

72、ce 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

73、trucks,play back historical paths, monitor the trucks automatically, but can also dispatch the trucks by voice and instructions, count the workload</p><p>　　5. Conclusions</p><p>　　1)Based on GI

75、 the system improves labor productivity and the production scheduling efficiency in mines considerably and saves investment and transportation costs.</p><p>　　2) From GPS pinpoint data, the system can deter

76、mine 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 a

77、n accurate basis for matching ore plans.</p><p>　　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<
