Powerline communication ( plc ) is one of the most powerful solutions for the " last one kilometer " problem . its advantages include laying no wires , wide span range and so on . based on the comprehension of ofdm modulation technology used in plc , this project bring forward a design and implementation of plc modem by using intellon ' s latest plc communication chip - - int5500cs . then on the basis of plc modem , the plc technology is applied to a remote electric meter 课题在深入理解应用于电力线通信的ofdm调制解调技术的基础上,利用intellon公司最新推出的plc通信芯片组int5500cs设计并实现了电力线通信调制解调器,实现了电力线通信与internet的结合,并在该调制解调器的基础上将电力线通信技术应用于远程电表当中,给出了基于plc技术的远程电表的技术方案和模拟实现。
The paper firstly introduces project - associated background and technology basis , followed with master plan of plc modem , hardware module division and implementation of each module . basic validation examples are given to test plc modem . then a prototype of remote electric meter applying plc tech is given . followed is the moudle division and implementation of this meter as well as the interface with meter reading software . it has been proved that plc modem and plc electric meter achieve basic requirement . the paper also concludes with key technique , testing problem and some experiences 论文首先介绍了课题的相关背景和技术基础,接着给出了电力线通信调制解调器的总体设计、硬件模块划分和各个硬件模块的具体实现。接下来给出了电力线调制解调器的基本测试例程及上网的测试,初步实现了电力线宽带通信。论文接下来介绍了基于plc技术的远程电表,给出了硬件、软件的模块划分和具体实现,同时给出了与远程抄表软件的通信接口和简单的模拟抄表系统。
This type of combined transformer consists of two single - phase all - insulated voltage transformers and two current transformers , divided into two types ? oil - immersed type and dry type , its primary and secondary outlet terminals are led out respectively through insulating porcelain jacket , outside the transformer tank there is equipped with electric meter box , which can be installed integrally with the combined transformer or hung up separately 本型组合互感器是由两台单相全绝缘的电压互感器和两台电流互感器组合而成,分油浸式和干式两种结构，其一、二次出线端子分别通过绝缘瓷套引出，箱体外侧配置电表箱，可与组合互感器一体化安装，也可独立悬挂安装。
It is not possible to tell how much of this reduction was a contribution made by this department , as immigration tower is occupied by 8 departments which share the use of 1 electric meter . however , since half of the 48 - storey building is occupied by this department , it is believed that our contribution was considerable 由于入境事务大楼有八个不同部门共用一个电表，因此难以确定在减少的耗电量中，本处所占部分究竟有多大，但本处的办公室占这幢48层高大楼的一半，故相信亦占相当部分。
Dds951 series electronic single - phase electric meter is the most advanced static electronic meter in china . the meter designs use large - scale intergated circuit . high reliability step motor , it can the ac single - phase active energv voltage rating : 220v : frequency 50hz , positive and negative two directions and accumulates in one direction . the test singnal is isolated by phototransistor : it also has the function of anti - fraud , and indicates it s operation situation on flash light , so it could be managed very easy Dds951单相电子电能表，是金雀仪表公司开发的新型电度表。该产品是采用规模专用集成电路，高可靠性步进电机等先进技术制造的国内最新电能试题新产品，用来计量额定电压为220v ，频率为50hz的交流单相有功电能，该产品能够精确计量正负两方向的有功电能，且以同一个方向累计。
