| Along with our country electric power enterprise's high speed development, the enterprise power load examination and control system has been used in some areas, and has made great progress. However, in the using electricity of management aspect, because user quantity are great, region distribution is broad, the job of Power Management depends on the manpower, no doubts increased the electric power company work load, and also do not achieve really automation. Make use of power network to Communication, build "power line carrier remote automatic meter reading system", do not need to invest the infrastructure and the daily line maintenance costs, high economy and reliability.This thesis discusses advantages and disadvantages of the power line carrier communication, analysis of the characteristics of low-voltage power line network, discuss the principle of spread spectrum communication technology. This thesis design a power line carrier communication technology based on remote automatic meter reading system, and describe in details the system design program, focus on hardware design and the function module of the main station. |
