Abstract :
The paper introduces a DSP based electricity meter system with multi-user and automatic meter reading capability. It consists of a PC based master meter in the control station and a reasonable number of slave meters in the local residential area. The power line carrier (PLC) technique is implemented so that bi-directional communication can be conducted between master and slave meters. Each slave meter was designed to replace fifteen or more conventional meters, significantly reducing the construction material and installation space for electricity meters. Experimental results show that the accuracy of remote meter reading between 2-4 am each morning is quite satisfactory
