The Auto-metering System Based On SSC P300 Which Can Spread The Frequency

With the people's living standards and the science and technology being constant to improve, the intelligent of family seems increasingly important to the lives nowadays. Due to the existing electronic equipments, such as network and controlling, communication, security guard, management, etc, all directly designed for the large-scale high-story building, the price is high, and difficult to use in the house built up.Power line network has definitely been spread to every house. Because of the high mechanical intensity and good dependability, power line network doesn't need the basic circuit construction investment and daily maintenance expenses to used in communication, so power line communication has higher economy and dependability, dispatcher in power system communication, production command, administration business communication and various kinds of information transmission can play an important role. The power line carrier communication technology can utilize the power line of low voltage to carry on data communication, not needing to set up the special-purpose cable again, the realization for the long-range data gathering and communication system offers very great convenience.This design is on the basis of using the power line as the communication medium, and we discussed the applications of a part of the family intelligence network-automatic metering system in community. The main research object of this design emphasizes on the most basic unit in the entire communication system-collecting. The main technology included in the research: 1~st static routing table algorithm; 2~nd power line carrier communication principle; 3~rd, MCU data signal collection technology; 4~th, I~2C bus communication. Moreover, this design also has made the review and the summary to the history of power line carrier communication, and forecasted its future.Although power line carrier technology not only in Europe, North America and in domestic has the quick progress in the field of turning on in the latest onekilometer", as well as constructing "the intelligent family". And both of them have the good prospects. But comparing with the traditional telecommunication technology, power line carrier technology is a baby, and has many imperfect places. In technology, correlation standard, cooperative organization, market spread, profit pattern and industrial chain aspect and so on, its formation is being faced with the multitudinous challenges, so the successful promotion of this technology needs the various endeavor. Automatically copies the table system based on the wide frequency carrier chip 300 plots is a relative economical solution, and this profession will be able to have a brighter prospect.
