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。 -
1. a small and cheap 8 - bit microcontroller is used as control core. all components of the sensor, some of which are necessary for the multiple and intelligent functions, are selected ones with low cost and small package. by designing all auxiliary logic circuits in a complex programmable logic device ( cpld ), and integrating all analog circuits in an application specific ic ( asic ), the size of pcb board is greatly reduced, which make it possible that the pcb can be installed with the displacement detector together
系統採用小型廉價8位微控制器控制，電路內配置了為實現多功能智能化所必需的硬體，並全部採用低價格、小體積器件，還將所有輔助邏輯電路設計在一片復雜可編程邏輯器件cpld內，所有模擬電路集成於一片專用集成電路asic內，大大縮小了電路板尺寸，再與傳感元件組裝在一起，從而使整個系統在保證智能化功能的前提下，具有體積小、成本低、一體化和抗干擾能力強的特點。
