Abstract
Abstract The present invention relates to a fault indication system in a centralized monitoring system for monitoring multiple devices speedily identifies and indicates a fault which is occurring, to improve maintenance of the monitored devices. The fault indication system includes multiple devices to be monitored, hierarchical multiple intermediate monitoring devices and a centralized monitoring device. The multiple devices to be monitored are connected to the centralized monitoring device via the hierarchical multiple intermediate monitoring devices. The centralized monitoring device is provided with time management tables corresponding to each of the multiple devices to be monitored and the hierarchical multiple intermediate monitoring devices. Information indicating the latest fault occurrence is recorded in the time management tables.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A fault indication system in a centralized monitoring system which detects fault conditions in multiple devices to be monitored comprising: hierarchial multiple intermediate monitoring devices each connected to a selected plurality of the devices to be monitored; and a centralized monitoring device connected to said hierarchial multiple intermediate monitoring devices; said centralized monitoring device having a computer with memory, said memory having a time management table for each of said multiple devices to be monitored and said hierarchial multiple intermediate monitoring devices, said centralized monitoring device recording in said time management tables the latest information indicating a fault occurrence in the monitored devices, said computer obtaining the latest information indicating the fault by reading said time management tables in said memory and processing said information in said time management tables to identify the latest information indicating a fault occurrence in time order.
Claim 2
Dependent Claim
142 words
A fault indication system in a centralized monitoring system which detects fault conditions in multiple devices to be monitored comprising: hierarchial multiple intermediate monitoring devices each connected to a selected plurality of the devices to be monitored; and a centralized monitoring device connected to said hierarchial multiple intermediate monitoring devices; said centralized monitoring device having a computer with memory, said memory having a time management table for each of said multiple devices to be monitored and said hierarchial multiple intermediate monitoring devices, said centralized monitoring device recording in said time management tables the latest information indicating a fault occurrence in the monitored devices, said computer obtaining the latest information indicating the fault by reading said time management tables in said memory and processing said information in said time management tables to identify the latest information indicating a fault occurrence in time order.
Claim 3
Dependent Claim
23 words
A fault indication system in a centralized monitoring system according to claim 1 wherein said multiple devices to be monitored are transmission devices.
Claim 4
Dependent Claim
25 words
A fault indication system in a centralized monitoring system according to claim 2 wherein said centralized monitoring device comprises a computer having said computer memory.
Claim 5
Dependent Claim
67 words
A fault indication system in a centralized monitoring system according to claim 3 wherein the fault is communicated from said devices to be monitored by a message indicating the fault occurrence, said centralized monitoring device receiving and storing said message and noting the time when said message is received, said stored message being linked to each of said time management tables in the memory of said computer.
Claim 6
Dependent Claim
52 words
A fault indication system in a centralized monitoring system according to claim 3 wherein said time management tables of said intermediate monitoring devices to which said devices to be monitored belong and the devices to be monitored are updated at the time the message indicating the occurrence of a fault is received.
Claim 7
Dependent Claim
135 words
A fault indicating system in a centralized monitoring system according to claim 5 wherein said computer is programmed to locate the latest fault from said time management table corresponding to the intermediate monitoring devices in said hierarchial multiple intermediate monitoring devices and identify an intermediate monitoring device having a message indicating the latest fault received by the hierarchial multiple intermediate monitoring devices, said computer being further programmed to locate a lower intermediate monitoring device having the message indicating the fault occurring at the latest time from said time management table corresponding to the lower intermediate monitoring devices monitored by the higher intermediate monitoring device, said computer being further programmed to locate the devices to be monitored in which the fault is occurring at the latest time by the lower intermediate monitoring device which is found.
