非传统通信技术在低压电力载波抄表系统中的应用
|
摘要
为解决“一户一表”繁重的电能参数采集问题,集中抄表系统应运而生,但其因电力线载波抄表系统抗衰减能力较差,未能达到商业推广。本论文采用非传统通道传输技术,以电力线作为传输通道,对系统进行了设计,完成了电子式电能表与modem的一体化,增强了发送信息的可靠性,采用长代码编码理论以及电压过零点信号传输技术设计编码发送器,并设计了新的编码方案,提高了系统容量。该技术降低了工程施工量,降低了系统的建设成本,提高了整个系统的运行可靠性。此外,由于信号传输采用码分多址技术(CDMA),保密性极高。
In order to solve the "a household a meter" electrical energy parameter gathering problem, the centralism record system arises at the historic moment. Because of the bad anti-damping ability of electricity line carrier wave record system, it did not achieve the commercial promotion. The paper uses the non-traditional channel transmission technology and transmits by the electricity line. It designed the system, has completed the integration of the electrical energy table and the modem, and strengthened the information transmission reliability. It used the long code theory and the voltage over zero signal transmission technical design code transmitter, and has designed the new code scheme, enhanced the system capacity.
This technology reduced the construction quantity, reduced the system construction cost, and enhanced the overall system movement reliability. Besides, the signal ling uses the CDMA technology, so its secrecy was extremely enhanced.
