Research on Wireless Data Acquisition and Transmission in Digital City Management

In order to solve the primary problems concerning city digitized management, and to reveal the relationships among information technology, network technology and multichannel digital communication technology, an architecture framework of the digital city supervion and management information system was put forward. Furthermore, some core technologies involved in this system platform were discussed in detail. Developing a set of high-performance wireless terminal information acquisition and transmission subsystem is the important foundation of a digital city system platform. As an important functional module in the platform, this subsystem should be at the very center of these major components within the digital city information system, so its three distinct layers and main processes were explained in this paper. For illustration, a set of software named Rizhao digital city supervion and administration information system was designed and realized according to the schema of this information system to show the feasibility and reliability of the platform construction solution. The running tests show that this system platform can provide a set of efficient and rich functionalities which can well meet the demands of a small and medium-sized city.
