【摘要】 随着网络信息技术的发展，住宅小区智能化、家庭自动化逐渐成为人们生活中不可缺少的一部分。智能小区信息网的建设将解决通讯网最后一个阶段的接入瓶颈问题，并把信息高速公路延伸到小区和家庭，让居民享有安全、便捷、经济和舒适的现代家居生活。 本课题家庭自动化系统方案是，在家庭内部用电力线作为通讯介质，通过基于扩频技术的CEBus网络协议构成家庭内部网，然后通过以太网或电话线远传到社区物业管理中心，社区物业管理中心再集中接入Internet，从而使整个小区构成一个开放的局域网络系统。 本课题对以太网通讯和MODEM通讯进行了编程、调试和实验，并完成了IP协议组的嵌入式实现。重点对电力线的扩频通讯系统做了大量的实验和研究，分析了扩频载波技术在电力线通信系统中的优势和主要问题，并提出了延长电力线传输距离的措施和方法。最后，将三部分通讯方式集成到家庭控制器中，解决了数字社区数据传输的问题，并做了一个演示系统。 以太网是一种非常成熟的技术，在未来的社区信息传输中必将得到广泛应用，而低压电力线作为传输介质还在研究之中，基于扩频通讯的电力载波技术一旦得到应用，将具有很大的经济意义。更多还原

【Abstract】 With the development of the network and information technology, smart-house community and house automation is becoming an essential part of the daily life of the people. The construction of the intelligent community will solve the last bottle-neck problem of the network, spread the information highway to the community home and bring the safe, advantageous, economical, comfortable life to the residents.The solution to house automation in the subject is, building a small-scale network with power lines within the home, connected with a remote controlling center in the community manage center through Ethernet or MODEM. In the manage center, the information can be inquired through the Internet. Thus the community will become an opened LAN system.In the subject, Ethernet communication and MODEM communication will be programmed, debugged and tested and the IP protocol group will be embedded into a single-chip computer system. My work focused on the experiments and research of the communication system through power lines based on the spread spectrum theory and analyzed the advantages and main problems of the system. In the last, I integrated the three communication patterns into the home controller, solved the problem of the data transmission and completed a demonstration system.Ethernet technology will be used popularly in the control of the home and community, but the communication system through the low-voltage power lines is still in research. It is predictable that the power line network based on the spread spectrum will be of great significance in the future.更多还原
