摘　　要：在国内的电能采集系统中大部分低压集中器都采用电力线载波模块作为抄表模块。但载波通信易受到电力线上存在的噪声干扰,抄表成功率经常达不到电业局要求。针对这一问题,文中提出了采用数据结构中的链表来进行集中器的抄表管理,并在嵌入式集中器上进行了编程实现。集中器在现场的抄表成功率的统计,显示该方案与传统抄表相比可以有效地提高集中器的电表抄通率和效率。Most low-voltage concentrators use power line carrier （PLC） module as meter reading module in energy ac- quisition system. But the carrier communication is subject to noise interference of power line, and the success rate of reading often fails to meet grid requirements. To solve this problem, this paper takes two-way linked list as manage- ment tools of the carrier meter reading, and programs in concentrator based on Linux embedded system. With the tra- ditional method of meter reading, the operation results and practice show that this design can effectively improve the reading success rate. and imnr,~v,~ th A;~ ~＇~：_：
