Research And Application Of Remote Automatic Meter Reading System Based On Power Line Carrier Communication

With the progress of the electric business management technology,the mode of electricity meter reading has also changed obviously,and the traditional manual meter reading is also eliminated.The power line carrier meter reading system begins to appear and has a large number of applications.This system does not need to lay the line,and has many advantages.But affected by the channel characteristics of low voltage power line,there are many defects of power line carrier meter reading system,the specific performance of real-time is not high,high stability,difficult maintenance etc..In order to eliminate these shortcomings and reduce the cost of the system,we should optimize the design of the meter reading system and improve the real-time performance to meet the related requirements of the meter reading system performance,which has also become the research focus in this area.Based on the study of the first power line carrier communication concept and principle are discussed,and the low voltage power line carrier channel properties in detail,and the value of this kind of communication technology in the remote meter reading system is discussed,and then discusses the principle of the remote meter reading system and the corresponding relay routing scheme.The multi block electric energy meters in this system are usually placed in the same meter box,and the same terminal is set up,and the data of electric energy meter can be collected through this terminal.The collected data is then sent to the concentrator through the power communication mode.This thesis discusses the acquisition terminal function,and discusses the corresponding hardware working principle,this thesis presents a novel relay routing solution,has carried on the simulation test,the results prove that it can satisfy the requirements of convergence,and obtains the relay routing table information is also significantly faster.
