gms@sohu.comAbsact-W can achieve vehicle location tracking on

Internet by using GPRS ehicle loation terminal and

ombining with Internet technology and GIS tehnology.

The artile gives the design struture of GPRS ehile

loation network servie system. The system is divided

into the pars: GIS network workstations, network

communications server and GPRS vehile location

terminal. Then, the artile makes the brief introdution

to the funtion of three pars of the system: GIS netork

workstations are sponsible for sending command

"Setting GPS Loation Data Return Interval" to

network communications server, and eiving GPS

loation data paket uploaded from GPRS vehicle

locatio trminal from nework communications server,

making analysis of eived GPS loation data packet;

The ehicles will be appead as title in the specied

position on the map by combining with GIS. Netork

ommuniations serer is responsible for receiing the

command "Seting GPS Location Data Return Interval"

from GIS network worstations and transmitting to the

specied GPRS vehile loation terminal and reeiing

GPS location data packet pass baked from GPRS

vehicle loation terminal and distributing to the

appropriate GIS network workstations simultaneously.

GPRS vehicle loation terminal is sponsible for

reeiving the command "Setting GPS Location Data

Rtn Iterval "sent fro netork comnications

serer and sending GPS loation data olleted by GPS

module to network communications serve Finally, the

article tests the feasibility of system design through

experiment. By using the system, it will be easy and fast

to make vehicle loation tracking on Internet and timely

acess vehile loation information.
