电力线载波通信在智能小区的研究与实现 A Design of Power Line Carrier Modem 专业班级： 学生姓名： 指导教师： 学 院： 2016年6月 摘 要 随着社会进步和科技发展，住宅小区智能化已经成为建设趋势和人们的生活品质追求。目前，电力线载波通信技术相对成熟、基本覆盖新建小区、建设成本较低，是实现小区智能化的最佳途径。本文对运用电力信道技术影响最为突出的噪声特性和衰减特性进行了分析，论证选择合适的调制方式；分析FSK调制电力线通信系统性能，设计调制解调器，提升抗干扰能力、传输距离和传输速率；根据 Visual Basic 6.0设计了智能小区中心管理软件,对小区内各部分远程控制和管理,对小区信息的收集、整理和 关键词：智能；电力线通信；；Visual Basic 6.0 ABSTRACT With the progress of society and the development of science and technology, the intelligent residential district has become the trend of construction and the pursuit of peoples quality of life. At present, the power line carrier communication technology is relatively mature, the basic coverage of the New District, the construction cost is low, is the best way to achieve intelligent community. In this paper the use of power line channel technology influence the outstanding characteristics of noise and attenuation characteristics are analyzed, argument to select the suitable modulation; FSK modulation for power line communication system performance analysis, modem design to enhance the anti-interference ability, transmission distance and transmission rate; according to Visual Basic 6.0 to design the intelligent community management center system, in order to on the part of residential were remote control and management, and achieve the area of information collecting, sorting and storage. On this basis, the intelligent community for communication testing and analysis, verify the reliability of the modem and software, demonstrated the feasibility of power line carrier communication in the realization of intelligent residential quarters.
