The Design Of The Communication Mode Of The Remote Meter Reading System

With the rapid development of our national economy, the power industry has been rapidly developed,and the electric load has been more and more heavy,and the construction has been more and more compolicate,distribution automation or the electricity is requested。As The current technology,electric power can not be restored,the production,transmission and the use of the electricity happened at about the same time.There for,the electric power industry must achieve the intelligent management or the Electric measurment,power-load control,Relay Protection,power dispatch,Fault detection and the Fault Isolation with the computer techonology,which based on the Electric measurement.; at the same time,in the reconstruction of the elcectric network, the Department of the Electric Power declared that our basic policy is-each home has a power meter,centralized meter reading and online service together with banks,whice supplies a wide platform for the modern management of the electric power,but also increases much work in meter reading and makes AMR became more urgent.Remote Automation Meter Reading System (AMR) of the electric power is a real time system,which can supply a rapide and accurate method of electric power energy collecting. So the communication mode is an Important guarantee for the real time and accurate AMR system. From the management system and present situations of electricity supply companies in China, this paper roundly introduces communication schemes and structurs that are now adopted widely at home and abraod,such as GSM,Bluetooth,spread spectrum carrier,and optical fiber communication. In order to meet the metric requirements of the electrice system in actual circumstance of different clients,a integrated communication scheme is designed on the base of the need of the field and the computation technique,and therefore,set up a real remote meter reading system. Energy- measure management System is an important part of the distribution automation system and Electric Power Marketing.As an important component of the management of electric energy use and the distribution automation system,the AMR system provides the basic necessary data for reducing operation costs and analyzing line loads.It helps the Department of the Electric Power improve their service,and it has great benefits to society and economy.
