Research On Field Management System Based On GPSOne Technology

More than 70% of information in people's daily lives is related to positions. People's need for position related information becomes more and more urgent. However, a person is dynamic; therefore, it is hard to acquire information about positions. How to acquire the information about the positions of a moving person or thing constitutes a significant research topic. Hence, the timely birth of wireless positioning technique as a kind of method by which people can acquire position related information. So, the development and enlargement of location services become the most potential Value Added Service.The fieldworkers' management system in this study is based on China Unicom CDMA 1 X, mainly using the positioning technique of the GPSOne that China Unicom provides, combining other related technique terraces like GIS, BREW etc, to provide clients with services like positions' fixing, warning, management of ambulant resources.The purpose of the system is to help companies to know the latest position of fieldworkers' and keep an eye on their past and present itinerary, and carry out the auto or half auto adjusting management of fieldworkers. The system is divided into seven modules, including resources positioning, management of routes of travel, supervision of the track, adjustment of business, statistics statement, customer management and system management. The system adopts SQL Server as its database management system and Brew technique for its moving terminal application development, and ASP.NET+ADO.NET and Visual C 6.0 for its terminal server's development.The main contents of this thesis include: the present condition and develop trend of positioning research, the comparison of various wireless positioning techniques, wireless positioning technique GPSOne based on the CDMA network, overall structure design of fieldworker's management system, design and realization of the system database, the realization of positioning and terminal software through OOAD, BREW programming, processing according to XML agreement, the design of system function mold pieces, outlook on future application of positioning business.
