MAINTENANCE MONITOR SYSTEM

摘要

PURPOSE: To attain a maintenance supervisory and operation system offering proper direction and guide even without a specialized knowledge by providing a multimedia multiplex communication means to a order wire channel so as to attain 2-way communication of audio, image and supervisory data. CONSTITUTION: A frame is sent through all order wires 3 of a remote system at a remote side from an order wire 3 of a node system A being a transmitter. A reception frame control section 4 demultiplexing the frame monitors a communication frame for each remote side system and when the control section 4 detects a communication request frame synchronizing signal, it is transferred to an operation section 5 as a communication request flag and a signal representing a kind of communication request. The operation section 5 displays the signal by lighting of a LED or buzzering so as to allow a maintenance personnel to recognize the signal. A signal processed to be a frame to select the order wire of the remote side system is transferred from the operation section 5 to a selection section 6 and an order wire frame is received by a multimedia multiplex demultiplex control section 7.
