Circuit arrangement for data transmission on the energy supply lines of an electric power supply network

摘要

A first optocoupler (OK1) DC decouples analogue data transferred on supply line (EL) and transfers onto a reception path (EPF). Reception path (EPF) is connected with analogue/digital converter, which converts analogue data transferred on reception path into digital data and feeds further to a digital signal processor (DSP) for further processing. In the opposite direction, digital data from digital signal processor for a transfer over the power supply line of the network (EN) are converted to analogue data by a digital/ analogue converter. Then analogue data is fed to second optocoupler (OK2) which DC decouples digital data onto the power supply lines of network.
