DESCRIPTION OF THE PREFERRED EMBODIMENTS In describing the embodiments of the device of the present invention, the relationships among a plurality of plants necessary for understanding the device of the present invention will be described below. In general, the two plants A and B, even if they are related to each other, have different products to be manufactured, and therefore it is often necessary to independently perform monitoring control. For example, plant A is a reaction can for refining oil, and plant B is a boiler for reacting the raw materials of the reaction can. At this time, for example, the reactor A that is the plant A needs to be started / stopped every day, but the boiler that is the plant B often starts up once a month, for example. Therefore, when viewed from the HI device of the plant, the adjacent plant, for example, B is often in the normal operation state when the own plant is started / stopped or in an emergency, and the start / stop of a plurality of plants is started. Occasionally, they are carried out in order, and in an emergency, it is rare that all plants become urgent at the same time.

In such a case, it becomes necessary to increase the number of HI devices to be used for operation as the number of operation supervisors increases. Therefore, the HI device of the own plant may be used, for example, when starting / stopping the operation of another plant, or in an emergency, for example
By incorporating a part of the equipment into the monitoring and operation of the own plant to monitor and operate the HI equipment of other plants, it is possible to monitor and operate multiple plants with a small number of people without increasing the HI equipment. It becomes possible to operate, and the HI device can be efficiently utilized during normal operation, operation start / stop, and emergency.

The device of the present invention has been realized on the basis of the above idea, and the first embodiment will be described below with reference to FIG. In the figure, 1A is a control station for controlling a plant A such as a reaction can, and 1B is a control station for controlling a plant B such as a boiler. These control stations 1A and 1B are connected to individual control system LANs 2A and 2B, respectively. The reason is that when the plants A and B are distant from each other, it is advantageous in terms of cost and the like to install the two control system LANs 2A and 2B separately from each other.

Further, an information system LAN3 having a large transmission capacity is provided separately from the control system LANs 2A and 2B, and the plants A and B are monitored between the information system LAN3 and the control system LANs 2A and 2B. -Human interface (HI) devices 4A and 4B to be operated are connected.

The HI devices 4A and 4B are CRT display devices 5A and 5A having an input device such as a keyboard for displaying the plant operating state and necessary plant information.
5B and a human interface that takes in information from necessary constituent devices based on a predetermined program, executes predetermined arithmetic control, and transmits the result of the arithmetic control to the necessary constituent devices via each LAN 2A, 2B or 3. Stations 6A and 6B are provided.

In this way, the HI devices 4A and 4B are provided for the plants A and B, respectively. The plants A and B are related to each other, but since the manufactured products are different, they are independently monitored and operated. This is because it is desirable to perform

The HI device 4A (4B) specifically has the following functions. That is, start of operation /
Emergency recognizing means 11 for recognizing an operation stop or emergency, and software for inputting call data for identifying the partner HI device in an emergency and calling monitoring / operation software after recognizing the emergency etc. by the recognizing means 11. Call input means 12, monitoring / operation for receiving the monitoring / operation software (program) sent from the partner HI device after transmitting the call data by this input means, and displaying the monitor screen of the partner plant on its own monitor window Software screen window display means 1
3. Multiple plant software parallel processing operation means 1 for processing software of own plant and partner plant in parallel
4. Multi-plant monitoring / operation processing means 15 for monitoring / operating each plant displayed by this operation means 14
Etc.

Next, the operation of the apparatus configured as described above will be described. First, during normal operation of each plant A, B, each HI device 4A, 4B independently performs monitoring control. Therefore, the HI devices 4A and 4B perform alarm reporting and monitoring for each plant.

Now, during normal operation of the plant B, the operation supervisor judges that the plant A has started / stopped operation or other emergency, or the plant B has started / stopped operation or other emergency. Since an alarm or other message to notify the occurrence of the message is sent and the message is displayed at a predetermined display position of the own HI device 4B, the operation supervisor,
Recognizing that the plant A is in an operation start / stop operation or other emergency situation, and if necessary, by inputting a signal indicating that it has been recognized from the input device, the software for incorporating the monitoring / operating software of the partner HI device 4A is acquired. The software starts.

Here, during normal operation of the plant B, when the operation supervisor inputs the call data for specifying the HI device 4A from the input device and calling the operation / monitoring software, the software call input means 12 Run. The software call input means 12 adds data for transmitting monitoring / operation software to the data of the call destination based on the call data input from the input device and sends the data to the information system LAN 3.

The HI device 4A on the plant A side is an information system L
When the call data is received via AN3,
The operating software (program data) is transmitted to the HI device 4B via the information system LAN 3.

Here, the HI device 4B executes the monitoring / operating software screen window display means 13. The window display means 13 stores the monitoring / operating software from the HI device 4A, and then displays the partner monitoring screen based on the software as a window as shown in FIG. 21 of FIG.
Is a monitor screen of the plant B, 22 is a monitor screen of the plant A, and the monitor screen of the plant A shows, for example, a control target name (for example, valve name) and an operating state (open state), etc. according to the software. The operation status or the process status quantity is displayed at the relevant part of the process instrumentation flow chart.

After that, the HI device 4B is based on the multi-plant software parallel processing operation means 14 for both plants A and B.
Each of the plants A and B is individually controlled in accordance with the progress of the monitoring operation software described above, but the plant states of the control results are displayed in the windows 21 and 22, respectively, and at the same time, the operation keys as shown in FIG. 23 is displayed. Therefore, the operation supervisor can operate the valve of the plant A according to the contents of the touch key by selectively touching the operation key 23 of the valve V displayed in the window 22, for example. When the plants A and B are operated in parallel, the operation keys of, for example, two systems are displayed accordingly.

Further, as shown in FIG. 4 (b), TAG and NO are displayed in the window 22 of the A plant, and when there is a request of an object to be operated, the input device instructs the valve V of the plant A to be input. After that, the operation keys 23 are operated.

In the above embodiment, the HI devices 4B to H
Although the software for monitoring and operating the I-device 4A is called, it goes without saying that the same means and functions can be used in the opposite case.

Therefore, according to the above configuration, the HI device at the time of normal operation fetches the monitoring / operating software from the HI device of the plant where the start / stop of the operation and other emergencies occur and performs the monitoring / operation. Since it is performed, it is possible to monitor and operate the HI device that has already been monitored for the plant in which an emergency occurs, and it has the same effect as increasing the HI device without specially covering the HI device. Since it does not increase mechanically, the increase in personnel is small. Moreover, in an emergency, the HI device under normal operation is used to monitor and operate another plant, so that the plant can be efficiently operated and managed.

Next, a second embodiment of the device of the present invention will be described. The overall system configuration is the same as in Fig. 1,
The functions of the HI devices 4A and 4B may be configured as shown in FIG. 5, for example. That is, the HI device 4A (4B) is
Emergency recognition means 31 for recognizing the start / stop of operation or an emergency, and calling data for calling the monitoring / operation software by identifying the partner HI device in an emergency after recognition of the emergency by the recognition means 31. Software call input means 3 for input
2. After the call data is transmitted by the input means 32, the monitoring / operating software (program) sent from the partner HI device is received, and the monitoring screen of the partner plant and the monitoring screen of the own plant are displayed as shown in FIG. A multi-window display means 33 for displaying and a multi-window display, a multi-plant software parallel processing operation means 34 for processing monitoring / operating software of the own plant and the partner plant in parallel,
The comparison monitor / operation processing means 35, which operates the corresponding operation keys 23A and 23B while comparing the monitoring screens of the plants displayed by the operation means 34, is configured.

Therefore, in the case of this embodiment, the monitoring screen 21 related to the monitoring / operating software of the own plant and the monitoring screen 22 related to the monitoring / operating software of another plant are displayed in the same row in a multi-window manner. Therefore, when a plurality of plants are related to each other, the operation can be performed while being compared, and the entire plant can be properly operated.

The system of FIG. 1 is premised on the case where the two plants are far apart and the control system LANs 2A and 2B have a small transmission capacity, and the monitoring / operating software data is transmitted using the information system LAN3. However, if a plurality of HI devices 4A and 4B are connected to the information system control system LAN 41 having a large transmission capacity and a plurality of plants A and B are close to each other as shown in FIG. The monitoring / operating software data may be transmitted.

Further, as shown in FIG.
When A and 4B are commonly connected to the control system common LAN 2 in addition to the information system LAN 3, the control system common LA
It is also possible to use N2 to secure the independence of the monitoring / operation and to transmit the monitoring / operation software data using the information system LAN3.

In the above embodiment, the two plants A and B are described as an example, but the same can be applied to two or more plants. Further, any type or form of transmission line may be used as long as it can transmit soft data. In addition, the present invention can be modified in various ways without departing from the scope of the invention.
