Abstract :
As for data surveillance, the general packet radio service (GPRS) is the best candidate for always-on connection to any moving vehicles or individuals from the ground up to a few thousand feet above ground. Due to the inherent characteristics of GPRS, the client circuit design requires a central processing unit (CPU) with an appropriate operating system (OS) to activate point-to-point protocol (PPP) as well as IP addressed transmission control protocol (TCP/IP). This paper presents a system designed for clients to carry out GPRS connection, and send GPS and other data to a server system. For surveillance purpose, a geographic information system (GIS) is applied to track the clients on the electronic map. The system architecture and design concept are discussed. Circuit implementation and real world tests are demonstrated and verified. The data transmission delay is estimated within 0.75 seconds, while the surveillance period can be controlled from 5 to 120 seconds. The proposed system has been tested in ground vehicles to ultra light aircraft at 1000 feet with most areas in Taiwan.
