Design And Implementation Of Spread Spectrum Carrier Data Collection System

As the city modernization and home intellectualization, it is required to automatically manage the electricity, the water and the gas consumption. Power line is used as medium to transfer data and become prevailing in all kinds of electricity management system due to low cost. In order to solve the problem of interference of power line, the spread spectrum technology is used in the system. The experimental system has been established in shaan抶i machine tool factory and now works well.In the software design of application system, the database design is important. So the implementation of related database is discussed in this paper around the design of SSC (Spread Spectrum Carrier) data collection system. Firstly, the background, work situation, the hardware design and the software design of this system are presented. Secondly, the whole architecture and function of the system are given. Thirdly, the theory and implementation of related database in the system, which including conception design, logic design and data protection, are discussed emphatically. At last the fragment and replication of data are analyzed briefly in the process of transformation between C/S database and distributed database.
