<Prior Art> In recent years, in plants in the petrochemical industry and the like, information on the operating status of various parts of the plant or the operating status of several plants is centrally managed at a central control center. At the control center, information on the operating status is displayed on the CRT screen for operation control, a recorder, or a graphic panel, and based on this information, operation controllers can perform appropriate control operations on the control console and issue necessary commands to the field. It is operated and managed by a system that includes: In other words, information signals indicating operating conditions such as temperature and pressure measured by sensors installed in various parts of the equipment and piping that make up the plant are sent to the control center. is usually input to a computer installed in a control center, processed, and displayed as operation control information on the screen of an operation control CRT installed on a control console.
A plurality of control consoles equipped with this CRT for operation control are provided as a set in order to cope with failures, etc., and each CRT for operation control displays the same operation control information or individually selected information. . On the control console of this set, there is one main operation controller who oversees the operation of the department corresponding to the displayed operation control information, and there is a CRT for operation control.
Driving operations and management are performed according to the information displayed on the screen.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional system, operation control information is concentrated on the main operation controller, and for example, when the operation control equipment or the manager of another department Unable to share operational control information, it may be difficult to quickly respond to abnormalities in plant operation, or it may be difficult to quickly obtain information necessary for making decisions, which may lead to problems with plant safety and There was a risk that this would cause problems in terms of stable operation management or that efficient operation management would not be possible.

Therefore, an object of the present invention is to solve the above-mentioned problem, and to enable the operation information supervised by the main operation controller to be shared with other operation controllers and managers, so that the operation control of the plant can be carried out efficiently. The purpose of the present invention is to provide a monitoring system for plant control that can be carried out efficiently and safely.

<Means for Solving the Problems> In order to solve the above problems, the present invention provides an image display means larger than an operation control image display means for displaying plant operation control information provided on a control console operated by an operation control tool. A plant control monitoring system characterized in that a monitoring image display means having a screen is disposed in front of a control console, and the operation control information is displayed on the screen of the monitoring image display means. This is what we provide.

Below, regarding the plant control monitoring system of the present invention,
A detailed description will be given based on the embodiment shown schematically in FIG.

In FIG. 1, 11.1□ and 13 are image display means for operation control; 2. ．． 2. and 23 are respectively 11.1
A control console corresponds to each of the operation control image display means 2 and 13, and 3 indicates a monitoring image display means.

In this system, information on the operating status in various parts of the plant is sequentially sent to the control computer 4 in the operation control room for processing, and the input/output control device 51.5□
and 53, and is displayed as image information on the operation control image display means 11.1□ and 13.・54 is a backup input/output device for backup in case of failure.

At this time, image information signals 6. is divided into signal 6+a and signal 6. by the distributor 7. The signal 6+a is input to the monitoring image display means 3, and the signal 6+b is input to the operation control image display means 11, and driving information is displayed respectively. In addition, the input/output control device 51, 52 or 53
are the control console 2. ．． The image information displayed on the corresponding operation control image display means 11.1□ or 13 connected to 22 or 23 is controlled. Further, a spare input/output control device 54 is connected to the control console 2□.

Operation control image display means 1. 12 and 1,
Information on the operating status is displayed as image information, or desired information is selected and displayed by the main operation controller operating the control console 22 or 23 to switch.

The main operation controller, while looking at the screen of the operation control image display means 11.1° or 13, mainly 1, on which this information is displayed, switches various control switches on the control desk so that the plant is operated appropriately. It is possible to operate the vehicle and issue driving instructions through communication means such as a telephone. For example, in the operation control of a chemical reaction plant, temperature, pressure, flow rate of reaction mixture, analysis value, material balance, basic unit, reaction Information signals indicating the operating status of the plant, such as status analysis values and abnormality diagnosis using AI, are sequentially input to the computer in the control room and processed, and the information is displayed on the operation control image display means 1. ．． 1. and 1. displayed as image information.

Operation control image display means 1. ．． 1. According to the information displayed in Appropriate measures, such as reporting, can be taken.

The image display means for operation control used in this system is
It may be a commonly used one, and is not particularly limited, and may be appropriately selected according to the type, amount, etc. of driving information to be displayed. for example,
A CRT display of about 20 inches is used.

At this time, in the method of the present invention, a monitoring image display means 3 larger than the operation control image display means 11.12 or 13 is placed in front of the control consoles 23.2 and 23. Control image display means 18.1□ and 1
3, and the monitoring image display means 3 is provided with the operation control image display means 1. The same image information as that displayed by the operator is displayed, and the operation status of the control console 11 that is mainly operated by the main operation controller is displayed.
