Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure monitoring system for a plurality of monitored devices.

[0002]

2. Description of the Related Art If a failure occurs in a group of monitored devices such as power devices installed in different places, for example, one of a plurality of power devices distributedly installed on each floor of a building, the failure is promptly detected. It is necessary to try to restore the normal operating state in response to the above, and as a countermeasure against this, a failure monitoring system as shown in the system diagram of FIG. 5 is used. FIG. 5 shows the case of a building on the third floor.

That is, for example, three monitored device groups 2 each including a plurality of monitored devices 1 installed on each floor
Monitoring devices 31, 32, 33 are provided for each of 1, 22, 23, and from there, to failure display devices 41, 42, 43, from monitoring devices 31, 32, 33 to installation floors and failure types The failure alarm line is directly wired for each (FIG. 5 shows the case of three types) and grounded to enable the failure display of each failure display device.

When, for example, a failure occurs in the monitored device 1 of the monitored device group 21, the device 1 grounds the failure alarm line according to the failure type, and the failure display circuit is closed via the monitoring device 31. The failure display device 41,
The failure display of the corresponding floor of 42 and 43 and the corresponding failure type is performed.

[0005]

However, in the failure monitoring system as described above, the wiring of the failure alarm line must be connected between all the monitoring devices and all the failure display devices for each failure type. The larger the scale, the more complicated the wiring of the failure alarm line becomes, resulting in poor workability and expandability.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a failure monitoring system in which wiring is greatly simplified and workability is improved.

[0007]

In order to solve the above-mentioned problems, the present invention detects a failure in a plurality of monitored device groups by respective connected monitoring devices, and the failure occurrence monitored device based on the failure detection information. In a failure monitoring system that displays a failure occurrence state for each installation type and failure type on a failure display section of a monitoring apparatus connected to a group to notify maintenance personnel, one of the monitoring apparatuses is a general monitoring apparatus, In response to failure detection information of all monitored device groups including the monitored device group monitored by the centralized monitoring device itself, a failure display signal is transmitted to display its own failure display section, and other monitoring devices are displayed.
As a subordinate monitoring device in which each failure display unit is displayed, all the failure display units of the integrated monitoring device and the subordinate monitoring device are displayed or not displayed when a failure occurs in the monitored device or when the monitored device is restored. It is a thing.

[0008]

According to the present invention, by the above means, it is not necessary to wire the fault alarm line between the respective monitoring devices for each installation floor / fault type, so that the workability and the expandability are remarkably improved.
