Under the background of the step electricity price reform,the transformation and upgrading of electric meters in the intelligent community has become the focus of the power sector.A design scheme of the meter reading system in the intelligent community based on the power carrier communication technology is proposed.The scheme adopts the distributed B/S mode,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 metering,power carrier communication and measurement and control host of user terminal,and gives the circuit schematic diagram and work flow of each module.The specific development scheme of the upper PC is described in detail,and the software flow chart and key codes are given.The engineering test shows that the power consumption of the intelligent community meter reading system based on the power carrier communication technology is less than 1 kW/month,and the measurement error is less than±0.1%,which can achieve the purpose of calculating the step electricity price and measuring the power consumption of the community users.The system has strong interference ability.When the surge and peak do not exceed 50%of the normal value,the system can work normally.
