Design And Implementation Of Remote Automatic Meter Reading System Based On Power Line Carrier Communication

With the development of the energy business management,the conventional meter way by people will be replaced by the auto meter reading system.Without laying line,meter reading system on low-voltage power line carrier holds the advantage over others to be the good choice to construct the auto meter reading system.In this paper,firstly,we expatiate on the concepts of the theory about the power line communication,analyze the characteristics of the channel of the low-voltage power line carrier,together with the performance of this technology applied to the auto meter reading system nowadays.Then it is investigated the function and the architecture of the meter reading system on low-voltage power line carrier.The routing algorithms currently used in the system is also investigated.Noticing that there are some meters installed in the same box usually,we can design a kind of equipment named as the terminal equipment for collecting the datum of the meters and sending to the concentrator.we explain the function of this equipment and the basic theory of the implementation of its software and hardware.Finally,a new routing algorithm,which can be applied in the meter reading system on low-voltage power line carrier,is presented.We emulate this algorithm and prove that it is convergent and has better capability than the former algorithm.
