|
摘要
本文研究并开发出一种用于电力线通信领域的电力线载波机调制解调模块。经过对系统功能原理的分析、几种方案的比较、硬件芯片(尤其是数字信号处理器与可编程逻辑器件)的选择，利用各种芯片的软件开发环境，编写出基于滤波法调制解调的系统软件程序，使用EDA软件完成电路原理图并设计出印制板图后，经安装调试，成功地开发出电力线载波机调制解调模块。该模块主要由数字信号处理器最小系统、模数转换电路、复杂可编程逻辑器件控制逻辑、看门狗电路、运算放大器电路和模拟滤波器电路构成。
实测和实际运行结果表明，该模块达到了原设计指标，进而提高了原系统的性能价格比，取得了良好的经济效益和社会效益。
This paper introduces the research and development of a modulation and demodulation module of Power Line Carrier, which is used in the area of power line communication. After analyzing the principium of system's function, comparing several projects and choosing the chips (especially Digital Signal Processor and Programmable Logic Device), the software program based on the method of filter is designed with the developing environment of chips. Then the circuit diagram is finished by the mean of EDA software and the printing circuit board is designed. Finally the module is accomplished successfully after installation and debugging. It mainly consists of the minimum system of DSP, A/D conversion circuit, CPLD control logic, watchdog circuit, OP amplifier and filter circuit.
The results of practical measurement and run show that the module meets the desirable requirements and improves the system's rate of performance and price. So the system has gotten well economic and social benefits.
