Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention provides a plant monitoring device for monitoring the operating status of a plant using an industrial television monitoring device and an automatic monitoring device using a data processing device. Regarding.

(Prior Art) Conventionally, in many cases, industrial televisions (hereinafter referred to as I) have been used as plant monitoring devices to visually monitor the operating status of plants.
A data processing device receives the operating status of the plant using a monitoring device (called a TV) and a detector installed in the plant.
An automatic monitoring device is used that displays and monitors the situation on a cathode ray tube (hereinafter referred to as CRT) display device.

(Problem to be solved by the invention) For example, when an abnormality occurs in a plant, data on the situation is displayed on a CRT display, but at the same time, the target of the abnormality is visually monitored using an ITV device. If you have to make a judgment about an abnormal situation, you need 5 more power.

In this case, in the above-mentioned conventional technology, the observer first
It is necessary to perform a procedure of determining the abnormal object on the T display device, then operating the ITV camera from the operation panel, selecting the vL viewing object, and displaying it on the ITV monitor.

The same applies when a change occurs in a plant, for example when equipment starts or stops.

In view of these problems, the present invention automatically detects the abnormality/change when the data processing device determines the abnormality/change in the plant.
I of places that require visual monitoring in response to changes
This allows display on a TV monitor.

[Structure of the invention]

(Means for solving the problem) In order to solve the above problem, ITV monitoring targets corresponding to plant abnormalities/changes are determined in advance by the data processing device,
When a certain abnormality/change occurs, the predetermined IT
The data processing device is provided with a function of outputting a V monitoring target selection command to the ITV control device.

Furthermore, the ITv control device achieves the objective by providing a function that allows selection of a corresponding camera, including turning, zooming, running, etc., based on a selection command received from the data processing device.

(Example) FIG. 1 shows an embodiment of the present invention.

In FIG. 1, the operating status of a plant 1 is transmitted to a monitoring room by an IT camera 2 and a transmitter 3, and visually monitored by an ITV monitor 4. In this case, ITV camera 2
], one or more cameras are installed, and each camera can be rotated, magnified, or moved in order to photograph the desired object. These include camera selection when there are multiple cameras, camera rotation,
expansion.

Traveling etc. can be performed freely by the observer using the operation panel 5 and the ITV control device 6 in the monitoring room, and the desired object can be displayed on the ITV monitor 4.

On the other hand, the automatic monitoring device reads signals from various detectors 7 installed in the plant 1 with the process input/output device 48, processes the data in the data processing device 9, and automatically
or at the request of the warden.

The operating status of the plant can be displayed on the display device 10 and monitored. ITV control device 6 from data processing device 9
An ITV monitoring target selection command 11 is sent to the ITV monitoring target.

A signal from a detector 7 installed in the plant 1 is read by a process input/output device 8, and the data is processed by a data processing device 9. At this time, if an abnormality/change in the plant is determined, data of the content is displayed on the display device 10. On the other hand, the data processing device 9 selects a predetermined ITV monitoring target in response to the abnormality/change, and outputs the selection command 11 to the ITV control device W16. Selection command 11
In response to this, the ITV control device 6 controls the ITV camera corresponding to the 1 selection command 11, and the rotation angle, enlargement, and travel location of the camera are predetermined, and the corresponding ITV camera is controlled. As a result, objects corresponding to abnormalities/changes in the plant are displayed on the ITV monitor 4.

By providing the above functions, when an abnormality/change occurs in the plant, the data of the content is displayed on the display device 10, and at the same time, the status of the target plant is automatically displayed on the ITV monitor 4. be done.

In the above explanation, an example was introduced in which a display device such as a CRT display device and an ITV monitor are provided separately, and each display the data processing result of the data processing device and the shooting screen of the ITV camera. There is also a method in which both displays are displayed in a superimposed manner on one display device. FIG. 2 shows an example of the configuration in that case.

〔Effect of the invention〕

According to the present invention, when an abnormality/change occurs in a plant and visual monitoring is required by an ITV device in addition to displaying processing data of a data processing device by a CRT display device, mutually related displays are provided. are displayed automatically and simultaneously, allowing supervisors to easily and quickly grasp the status of the plant, improving monitoring performance.
