Intelligent Meter Reading System of Community Based on Power Carrier Communication Technology
Abstract：Under the background of the step price reform, the transformation and upgrading of smart residential meters has become the focus of the power sector. This paper presents a design scheme of meter reading system in intelligent community based on power carrier communication (PLC) technology. This scheme adopts the distributed B/S mode. The paper introduces the working principle of power carrier communication technology, expounds in detail the design principle, parameter setting method and key technology of hardware modules such as power measurement, power carrier communication and measurement and control host at the user end, and gives the circuit schematic diagram and work flow of each module. This paper expounds the specific development scheme of the upper PC in detail, and gives the software workflow diagram and key code. The engineering test proves that the intelligent community meter reading system based on power carrier communication technology can achieve the purpose of calculating step electricity price and measuring and controlling the power and energy consumption of community users.
