Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized monitoring apparatus for a plurality of facilities, and more specifically, for monitoring the conditions of a plurality of important facilities such as vibration of turbine shafts in boilers, leakage of boiler tubes, and water quality control. It is applied to the case where it relates to a centralized monitoring device for multiple facilities, which can collectively monitor the results of monitoring by multiple individual monitoring devices installed corresponding to multiple facilities in a central control room, etc. is there.

[0002]

2. Description of the Related Art When installing a plurality of individual monitoring devices corresponding to a plurality of facilities, the installation time of these individual monitoring devices is different and the individual functions (basic and application software) are different. In, the monitoring computer models are often different from each other, or even if the models are the same, the grades are often different from each other. In this way, the monitoring results of a plurality of individual monitoring devices equipped with monitoring computers and monitoring CRTs of different models and / or grades from each other can be displayed on the screen of the central control room or the like to enable centralized monitoring. In constructing a centralized monitoring device, conventionally, a means for installing a plurality of CRTs corresponding to a plurality of individual monitoring devices in a central control room has been adopted.

[0003]

However, in the conventional centralized monitoring apparatus for a plurality of facilities as described above, the space occupied by a plurality of CRTs installed in the central control room is very large, and the behavior in the central control room is very large. There is a problem that not only the space is narrowed, but also the burden of monitoring by the observer is increased, and thus a mistake in monitoring easily occurs.

Therefore, the present invention has been made in view of the above situation, and the invention according to claim 1 uses the application software peculiar to a plurality of individual monitoring devices as it is, while maintaining the central control room. Single CR installed in
Using only T, it is possible to selectively display the monitoring screens of a plurality of individual monitoring devices of different models and grades and to easily and centrally monitor a plurality of facilities. The purpose is to provide a centralized monitoring device.

The invention according to claim 2 is the above-mentioned claim 1.
In addition to the object of the invention described above, it is an object of the present invention to make it possible to effectively utilize the functions originally possessed by the individual monitoring device to simplify the overall configuration and reduce the cost.

Further, in addition to the object of the invention described in claim 1 or 2, the invention described in claim 4 is, in the case where an abnormality occurs in the monitored items by each individual monitoring device, the target device of the abnormality occurrence and the abnormality thereof. The purpose is to promptly display the relevant screen of the occurrence so that the cause of the abnormality can be investigated accurately and promptly.

[0007]

In order to achieve the above object, the centralized monitoring apparatus for a plurality of facilities according to the invention of claim 1 of the present invention is installed corresponding to each of a plurality of facilities and mutually A plurality of individual monitoring devices equipped with different types and / or grades of monitoring computers and monitoring CRTs, and an input operation similar to the input operation for each monitoring computer installed in the central monitoring room. A single computer capable of selectively calling a monitoring signal from each monitoring computer according to, and a central monitoring device having a single CRT displaying a monitoring screen corresponding to the monitoring signal selectively called by the computer. The multiple individual monitoring devices operate according to their own application software. And a plurality of equipment individually monitors and displays the monitoring screen on the individual CRT corresponding to each Te. In this state, by performing an input operation similar to the input operation to the monitoring computer in the desired individual monitoring device to a single computer of the central monitoring device installed in the central monitoring room, the corresponding individual monitoring device It is possible to call the monitoring signal by the CRT and display the monitoring screen corresponding to the calling monitoring signal on the CRT of the central monitoring device.

As a result, it is not necessary to add special communication software, and it is possible to simplify the configuration of the entire apparatus and reduce the cost. Further, at least one individual monitoring device among the plurality of individual monitoring devices (especially when the X window is not installed in the monitoring computer of the individual monitoring device), as described in claim 3, It is possible to add communication software to the individual monitoring device side and call a monitoring signal of the individual monitoring device via this communication software to realize centralized monitoring.

Further, in the centralized monitoring apparatus for a plurality of facilities according to the invention described in claims 1 to 3, as in claim 4, an abnormality occurs in the monitored items by the plurality of individual monitoring apparatuses and an alarm is issued. When the alarm signal is received, the computer on the central monitoring device side receives priority and automatically identifies the target individual monitoring device in which an abnormality has occurred, and displays the screen of the identified individual monitoring device on the central monitoring device side. By adding a configuration to display on the CRT, if an abnormality occurs in the monitored items by each individual monitoring device, the target device of the abnormality occurrence and the relevant screen of the abnormality occurrence are immediately displayed to identify the cause of the abnormality in the central control room. It is possible to accurately and promptly investigate in.

Further, in a fifth aspect of the present invention, in the centralized monitoring device for a plurality of facilities according to the first to fourth aspects of the invention, the video signal imaged by the ITV monitoring camera is a CRT on the side of the central monitoring device. In this case, the video signal picked up by the ITV surveillance camera is also optionally displayed on the CRT in the central control room, especially the appearance and surroundings of the equipment. It can be effectively used for monitoring.
