The Research and Realization of Traffic Service System Based on GPS and GPRS
In recent years, data service has been gaining popularity in embedded system and general packet radio service (GPRS).GPRS is one of the next-generation wireless communication technologies. This paper takes advantage of seamless GPRS data coverage and its good capacity to combine GPRS technology and GPS system, realizing real-time positioning of vehicles. This paper describes structure of the system using GPRS and GPS technology for real-time data acquisition and transmission. It transmits the data through GPRS network to the background system for centralized data processing and analysis. The analysis results are given back to administrator rapidly and timely through the wireless network. This module not only saves development and maintenance costs of a private network, and takes full advantage of the unique advantages of GPRS. Finally, this paper summarizes characteristics and advantages of the system in practical application and has good prospects.
