毕业论文(设计) 论文题目:基于电力网载波通讯的电器控制系统 院 系 航空电子电气工程学院专 业 班 级 电1102 学 号 201100142020 姓 名 指导老师 2014年 月 日 Abstract Power line carrier communication technique appeared in the early 20s of the twentieth Century, power line carrier is the basic means of communication power system specific. Power line carrier communication refers to the use of existing power network, the analog or digital signal transmission technology by carrier modulation. It can be used to transfer the telephone, remote data and tele protection signal, is to ensure grid safety, quality, economic operation, one of the important means of communication dispatching automation and management modernization. It takes the power network as transmission channel with channel,high reliability, less investment and quick, and synchronized power grid construction etc.. Power line curriculum design selection of Qingdao Softened SSC1641 carrier chip the chip has modulation solution, a/d, d/a communication function, the chip of digital signal processing, which greatly improves the reliability of communication.This paper includes his peripheral circuit, signal amplifier, coupling, filtering, and finally realizes the function. The noisy signal receiving power line, and then to the single-chip microcomputer to the signal filtering analog digital conversion process by sending serial communication, microcassette after data processing through the LCD1602 display, and also through display serial communication to send to the PC machine. PC machine or a switch circuit of input signal is processed by SSC1641through the power line transmission. Such a system in order to complete the receiving and sending signal, the forma
