This paper mainly focuses on the noise limiting by means of the direct sequence spread spectrum ( dsss ) and the analysis of the transmission performance of the plc and some digital modulation technology. the contents of the paper is as follows : 1 ) the technical feasibility is proved after simulating noise limiting principle of dsss by means of systemview, the simulation software ; 2 ) a kind of band pass filter ( bpf ) is realized according to the requirement of filter and the principle of butterworth approximation, which satisfies the index of performance of dsss. 3 ) the low voltage plc system includes the sc1128, the specific modulation / demodulation ic, the bpf filter and other circuit components, furthermore, the control function of system is realized by means of the personal computer and the microcontroller
本課題在對低壓電力線的傳輸特性和數字調制技術進行分析的基礎上，將通信理論中的直接序列擴頻技術（ dsss ）用於解決低壓電力線通信的干擾問題，主要研究內容如下： （ 1 ）用通信模擬軟體systemview對dsss技術的通信和抗干擾原理進行模擬分析，分別對時域和頻域下採用dsss技術前後接收信號的頻譜進行分析，驗證dsss技術在本系統中的可行性； （ 2 ）由dsss技術對濾波系統的要求，根據濾波理論分析了巴特沃思型濾波器的逼近原理並設計了合適的濾波電路； （ 3 ）用調制解調晶元sc1128和自行設計的濾波器加之輔助外圍電路，構造出低壓電力線載波通信系統，並採用atmel公司的單片機設計了接收和發射電路的微控制器； （ 4 ）分別對採取抗干擾措施前後輸入和輸出信號進行對比實驗，並對結果進行分析，驗證了dsss技術對干擾信號的抑制作用。As the first to provide direct digital control technology for building automation, the first to embed a web server in a building controller and the first to provide complete integrated solutions based on open systems for building it, a company of profound service culture and professional knowledge, with the help of its parent company, schneider electric s source advantages, tac has acquired quick development in chinese market and participated the prestigious projects, such as national theater, national high court, guangzhou exhibition centre, beijing friendship hospital, tsinghua university sports centre and so on
C .憑借母公司施耐德的優勢資源已經在中國市場獲得了長足的發展，先後承攬了包括國家大劇院、最高人民法院、廣州會展中心、北京友誼醫院及清華大學體育中心在內的一系列國家重點工程。而施耐德電氣在實現對tac及安德沃的收購、重組后將更加從容面對2008年北京奧運會及2010年上海世博會帶來的機遇和挑戰。So keenly prepared was rosewall that against the game ' s biggest servers he was able to let the ball come well into his hitting zone and then lash the ball sharply enough to compromise both netrushers and baseliners
在面對重要的接發球時，羅斯沃爾總是早早做好準備讓球落到他的擊球范圍之內，然後再猛地將球回擊，讓他的對手無計可施? ?無論是發球上網型選手抑或底線型選手。
