DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring and control device for monitoring and controlling the operation of various equipment in a process to be monitored.

[0002]

2. Description of the Related Art Conventionally, water and sewage plants, buildings,
Monitoring and control devices that monitor the operating status of equipment installed in factories and other various plant instrumentation control systems include:
A wide variety of equipment such as pumps, motors, valves, and water tanks are used in the monitored process.

In recent years, in order to monitor a process to be monitored provided with such various types of equipment, a method of displaying and monitoring the operation status of each equipment using a CRT display on a CRT display has been proposed. FIG. 5 shows a conventional example of a monitor and control device provided with such a CRT display device. This conventional monitoring and control device includes a monitoring target process 1 in which a large number of equipment devices are installed, and a central monitoring device 2 for monitoring the operation state of each of the equipment devices included in the monitoring target process 1. .

[0004] In the process 1 to be monitored, an appropriate number of ITV cameras 3 are installed in order to capture the operation state of each equipment.

On the other hand, the central monitoring device 2 collects process information related to the equipment and monitors the presence or absence of an abnormality, and displays a process information monitoring system that displays when an abnormality occurs, and captures and displays video information of each equipment. It consists of an equipment monitoring system.

[0006] In the process information monitoring system of the central monitoring device 2, the process status monitoring control unit 4 collects process information from various equipment of the monitored process 1 via the process input / output device 5 and stores it in the storage device 6. At the same time, the process information is compared with upper and lower limits or allowable values of various pieces of process information registered in the storage device 6, and when it is determined that there is an abnormality, the abnormal state is output to the CRT display device 8 through the screen display controller 7 and displayed. , An operator is notified of an abnormal state. In the figure, reference numeral 9 denotes an input terminal for giving a necessary operation input, which is constituted by one or a combination of a keyboard, a mouse, a touch screen and the like.

The equipment monitoring system of the central monitoring apparatus 1 which is different from the above-mentioned process information monitoring system is configured such that when the CRT display device 8 of the process information monitoring system displays an abnormal state, the operator switches the corresponding equipment. By specifying the ITV camera 3 capable of capturing an image and operating the ITV control device 10, the user selects the relevant ITV camera 3 installed in the process 1 to be monitored at a remote place through the dedicated communication line 11.
The control information for adjusting the direction and the focus is transmitted, and the video signal from the corresponding ITV camera 3 is similarly transmitted to the dedicated communication line 1.
1 and displays it on the CRT monitor device 12 of the facility equipment monitoring system.

Thus, the operator normally operates the CRT
The state of each equipment in the process to be monitored in the remote place is monitored while looking at the display device 8, and when an abnormality occurs in any one of the equipment, the image of the corresponding equipment is displayed on the CRT monitor device 12. An abnormal state is determined while looking at the display of both, and a recovery process for the abnormal state is taken. That is, the process state of the target equipment is grasped from the display screen of the CRT display device 8 at the time of operating the device, and the operation state of the facility equipment of the process to be monitored and controlled is grasped from the display image of the CRT monitor device 12. Based on the above, an operation command such as operation / stop of the corresponding equipment is input from the input terminal 9 and the operation result is displayed on the CRT display device 8 and the monitor device 12 again to confirm the state. It is.

As described above, in the recent monitoring control apparatus, the equipment equipment monitoring system is provided separately from the process information monitoring system because the process information monitoring system checks only the plant information of the monitoring item registered in advance. Because
This is because the situation around the equipment at the time of occurrence of the abnormality is to be grasped through a video for information that cannot be detected by a sensor of the equipment.

[0010]

However, such a conventional supervisory control device has the following problems.
In other words, the process information monitoring system that monitors process information and the facility equipment monitoring system that uses cameras are completely separate systems. The process information monitoring system automatically identifies the relevant ITV camera for the equipment that has detected the occurrence of an abnormality, and takes an image of the abnormality-occurring device and its surroundings, and monitors the video information. Since the information cannot be displayed on the apparatus, the operator must perform these series of operations at his / her own discretion.

Further, since a process information monitoring system for handling digital signals and a facility equipment monitoring system for handling video signals are separately provided, a space for installing each monitoring system is required. Information to be provided also needs to be performed using a separate communication line, and there is a problem in that equipment costs are increased. In particular, these points
In recent years, the processes to be monitored have been increasing in size and complexity, and the number of items of equipment to be monitored has been increasing, and the amount of information to be acquired has been extremely increased, so that the equipment costs have increased. However, cost reduction has been a major issue.

The present invention has been made in view of such a conventional problem. By coordinating a process information monitoring system and a facility equipment monitoring system, the burden on an operator when an abnormality occurs can be reduced. It is another object of the present invention to provide a monitoring and control device capable of improving a space factor and reducing equipment costs.
