Claims

[Claims for Utility Model Registration] 1. A plurality of child monitoring devices provided at a relay station of a communication circuit system to collect monitoring information of the communication circuit system, and a plurality of child monitoring devices provided at both end stations of the communication circuit system and said child monitoring devices In the centralized monitoring device, the central monitoring device includes a parent monitoring device that collects monitoring information sent from the devices, and a central monitoring device that collects monitoring information sent from the child monitoring devices via the parent monitoring device, wherein the communication circuit (A) When the communication circuit system is normal, the first parent monitoring device installed at one end station of the system does not collect the monitoring information sent from the child monitoring device, Detects the disconnection of a supervisory control signal that controls the monitoring function sent by the opposing parent monitoring device when the power is off, sends a signal disconnection detection signal to the central monitoring device, and automatically collects information on the child monitoring device. (B) receiving a signal loss detection signal from the first parent monitoring device, and detecting a signal loss from both parent monitoring devices including the first parent monitoring device; 1. A centralized monitoring device comprising: priority information processing means for determining which of the monitoring information sent from the child monitoring devices is to be prioritized. 2. The centralized monitoring device according to claim 1, wherein the monitoring control signal is a polling signal.
