基于INT51 X1芯片的调制技术在10kV配电网自动化通信系统中的应用

Application of the modulation technique based on INT51XI chipset in telecommunication system for 10 kV power distribution network

在10kV电力线上实现高速数据传输有着广阔的应用前景和经济价值,但是由于电力线信道存在着不可预期的高噪声、多径效应和信道衰落,严重制约了高速数据的传输。而近几年兴起的无线信道上实现高速数据传输的新技术,即OFDM(多载波正交频分复用)技术,是解决这些电力线通信问题的有效方法,文中提出了一种基于美国Intellon公司的INT51X1电力通信专用芯片并结合台湾Winbond公司32位ARM7TDMI内核的RISC微处理器W90N740的PLC通信系统的设计。

High-speed data communication over 10 kV power line is an active field with broad application perspective and economic benefits. But due to the unpredictable high noise,multi-path effect and path attenuation,power line channel is difficult for transmitting high-speed streams. OFDM which is an emerging technology for wireless high-speed communication in recent years,it is an effective solution to these problems in power line communication. This paper represents the design of the PLC communication system based on the chip INT51X1 which is dedicated to power communication and 32-bit ARM7TDMI based RISC microcontroller W90N740.
