RIPPLE CONTROL SYSTEM FOR A SUPPLY AREA

摘要

In ripple control systems (RKG, RS) the problem exists of being able to establish whether the emitted audio-frequency telegrams have been actually and correctly received at all points of a supply area (NS). For this purpose, a ripple control system (RKG, RS) is proposed which additionally contains: monitoring receivers (UE) are situated distributed in the supply area (NS), which receive emitted audio-frequency telegrams and buffer them; a monitoring central office (UZ), which can be connected to the monitoring receivers (UE), in order to receive the telegrams buffered in the monitoring receivers (UE) and compare them to the telegrams emitted by the ripple control command device (RKG).
