BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant supervisory control device for operating a plant by a plurality of operation input devices each having a display device.

[0002]

2. Description of the Related Art Recent plant monitoring and control devices have been designed to replace plant centralized monitoring operation panels with a large number of operation switches, indicators and recorders in order to reduce the burden on operators due to complicated plant configurations. An operation input device is provided for displaying the (operating end) state on a plurality of display devices for each system and for instructing an operation for each display device. As described above, a plurality of configurations are provided so that the same plant equipment can be operated by a plurality of operation input devices. Such a thing is disclosed in, for example, Japanese Patent Laid-Open No. 63-12.
It is described in Japanese Patent No. 0396.

In such a plant monitoring and control apparatus, since the same plant equipment can be operated by a plurality of operation input devices respectively, when another operator operates the plant equipment under operation, the operation interference due to the overlapping operation occurs in the plant. There is a problem with safety. Conventionally, with respect to the problem caused by this duplication operation, the plant equipment in operation cannot be operated by another operator, and when another operator requests an operation, the operation is not performed because the corresponding display device is being operated by another operator. It shows that it is possible.

[0004]

However, if the operator makes an operation request and confirms by the presence or absence of a display indicating that the display device is inoperable because another display device is being operated by another, the operation efficiency will be poor. Confirmation errors may occur due to display delays. Further, even if the plant equipment is operable, the operation may affect the plant equipment being operated by another operation input device, which may lead to a decrease in operation efficiency and a danger to the plant. .

It is an object of the present invention to provide a plant monitoring and controlling apparatus which has a high operation efficiency and can perform a safe plant operation without interference of operations.

[0006]

The feature of the present invention resides in that the operation status according to the operation command from the operation input device is displayed on each of the plant equipment displayed on the plurality of display devices. .

Another feature of the present invention is that the operation history of the plant equipment is displayed by designation by an operation command of the operation input device.

[0008]

[Operation] By monitoring each plant equipment and displaying the operation status on the display device in real time, the operator can easily confirm the operation status of each plant equipment.
The driving efficiency can be improved. In addition, displaying the operation status can prevent redundant operation by the operator, and in addition to preventing redundant operation by the operation monitoring unit, double operation can be prevented and plant safety can be improved. You can Furthermore, by displaying the operation history of each plant device on the display device, it is possible to prevent the operation from affecting the operation from other operation input devices and improve the safety of the plant.
