【摘要】 随着科技的进步和人民生活水平的不断提高,住宅智能化在当今生活中显得日益重要起来。但是由于现有布线网络和监控、通信、保安、管理等设备都是针对大型高层楼宇的,价格高,且难以在建成的住宅中使用,所以人们找寻并开发了一种简单有效且经济的方案。 电力网是一个近乎天然、入户率绝对第一的物理网络。由于电力线机械强度高,可靠性好,用于通信不需要线路的基础建设投资和日常的维护费用,因此电力线通信具有较高的经济性和可靠性,在电力系统的调度通信、生产指挥、行政业务通信以及各种信息传输方面可以发挥重要作用。低压电力线载波通信技术能够利用低压电力线进行数据通信,不需要再架设专用电缆,给远程数据采集及通信系统的实现提供了很大的方便。 本设计就是在电力线为通信介质的前提下,探讨了家庭智能网络的一部分应用——小区自动抄表系统。本设计主要的研究对象的侧重点是整个通信系统中的最基本单元——采集器。研究中主要涉及的技术有:1、静态路由表算法;2、载波通信原理;3、单片机数据采集技术;4、I~2C总线通信技术。另外,本设计还对载波通信的历史作了回顾和总结,并对其未来发展做出了展望和预测。 虽然电力载波技术(power line carrier)不论在欧洲、北美等地区还是国内在“最后一公里”接入,以及构建“智能家庭”中都有较快的进展,具有良好的发展前景。但是相对传统电信技术而言是一个新生儿,有很多不完善的地方。在技术、相关标准、合作组织、市场推广、赢利模式和产业链的形成等方面面临众多的挑战,该技术的成功推广需要多方面的努力。基于扩频载波芯片Intellon SSC P300的小区自动抄表系统是一个相对经济的解决方案,而该行业将会有更光明的前景。更多还原

【Abstract】 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.更多还原
