DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant operation device for operating plant equipment using a display input device such as a CRT.

[0002]

2. Description of the Related Art In recent years, in a large-scale and advanced plant such as a nuclear power plant, many intelligent display / input devices such as a CRT have been introduced to monitor the plant and operate equipment.

In general, the display input device sequentially switches display screens according to the operating state of the plant and the timing of equipment operation, and operates plant equipment in accordance with the display screen. As this type of plant operation device, a device in which a display device and an operation device are integrated, and a device in which a display device and an operation device are interlocked separately are widely used.

FIG. 13 shows an example of a conventional plant operating device.

[0005] Here, a description will be given of a plant operation device in which monitoring and operation can be performed on the same screen of the display device, and operation of the plant is easy and space can be saved.

[0006] The plant operation section 1 comprises a process input means 2, an operation information display means 3, an operation input means 4, an operation information processing means 5, and an operation output means 6.

The plant input unit 2 of the plant operation unit 1 is connected to a plant device 8 and a control unit 9 via a process input unit 7, while the operation output unit 6 is controlled via a process output unit 10. It is connected to the device 9.

The operation information display means 3 includes a display device 1
1 is connected, and the input device 12 is connected to the operation input means 4.

In the above configuration, the process input means 2 inputs the plant information of the control device 9 and the plant equipment 8 via the process input section 7. The plant information input by the process input unit 2 is displayed on the operation information display unit 3, and the processed plant information is displayed on the display device 11.

The input device 12 detects a position touched on the screen of the display device 11 by an operator using, for example, a touch input device. The position detected by the input device 12 is output to the operation input means 4. Operation information processing means 5
Processes the operation request information based on the position touched by the operator from the operation input unit 4. Operation output means 6
Inputs the operation request information processed by the operation information processing unit 5 and outputs an operation command to the control device 9 via the process output unit 10.

The control device 9 receives an operation command, performs control processing, and outputs a control signal to the plant equipment 8.

In such a plant operation device, an operator monitors the plant device 8 on the display screen of the display device 11, selects an operation target device of the plant device 8 using the input device 12, and executes an operation. . In this case, for the display device 11, for example, an appropriate screen is automatically or manually selected from several tens to several hundred screens prepared in advance. The operator can easily operate many devices to operate the operation target device based on the selected display screen.

As described above, recent plant operating devices include:
Monitoring information and operation information are centralized, making the operation panel compact and facilitating plant operation.

[0014]

However, the above-mentioned plant operating device has the following problems.

For example, the above-described plant operation device is easy to operate, but has various functions in one display device 11 and one input device 12. For this reason, there is a possibility that a completely different plant equipment 8 may be selected and an erroneous operation may be performed even if the operations are similar in appearance. Further, there are some operations of specific equipment of the plant equipment 8 which can be performed only by a specialized expert and those which can only be started or stopped by the specific person.

Also in such a case, any of the above-mentioned plant operating devices can operate all the plant equipments 8 by the operator. In addition, no one of the operators performed any operation. For this reason, there has been a request to prevent the operation of the plant equipment 8 by an operator other than the operator who has been allowed to operate in advance. further,
It was necessary to record the contents of the operation of the operator and manage the responsibility and the operation history.

For example, during maintenance work on the plant equipment 8 (for example, disassembly and inspection of valves and pumps), during a test, at the time of start-up or stop, operations other than those who are permitted to operate in advance are prohibited. You. Furthermore, it is necessary to prevent accidents by limiting the operation target devices according to the skill level of the operator.

In order to solve this, conventionally, an operation prohibition tag or the like is attached to the switch so as not to be operated.
Inadvertent operation was sometimes performed by carelessness.

Conventionally, there has been a device for preventing careless operation using a release button (Japanese Patent Laid-Open No. 1-1525).
01). However, this also does not separate the person who permits the operation and the person who prohibits the operation for each operator and for each plant equipment to prevent erroneous operation, and cannot meet the above-mentioned request.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a plant operation device having a management function capable of preventing an operation by an operator other than a previously permitted operation target device.

In the above configuration, first, the operator inputs personal device operation information as personal data and data relating to the device to the plant operation section 1 in advance by using the data input CRT keyboard 18a as shown in FIG.

Specifically, first, a data input CRT
The display screen of the attached keyboard 18a is a personal device operation information setting screen 31 as shown in FIG. On this display screen, a processing type is selected from the keyboard 18a with a CRT for data input. In this case, "1" is input as a new input.
Thus, in the case of a new input, the ID No. Is displayed as a number. At this time, ID No. If up to 10 has been entered, ID No. Is displayed as “11”,
To enter a completely new ID No. 1 is displayed.

Then, in Roman characters, for example, "Har
a ". Next, under the system name, "1" is input sequentially if operation is permitted, and "0" is input if operation is not permitted.

Modification and deletion are performed in substantially the same manner. In this example, ID No. 32, NAME "Har
a ", system RHR" 1 ", RCIC" 0 ", SGTS
“0”... Are input.

As a result, the personal device operation information database 32 is created by the processing of the personal data registration processing means 17 as shown in FIG. In this example, ID No. Each time is composed of a name (for example, Aoki) and a system name (for example, RHR) that can be operated, and is “1” when the operation can be performed and “0” when the operation cannot be performed.

A keyboard 1 with a CRT for data input
8a, device data as information on the device is input. Thereby, the device database 3 configured as shown in FIG.
3 is stored in the device operation information determination unit 21. In this example, a system number and operable devices are stored for each system name. For example, in the system name RHR, the system number E1
1. Operable devices F001A,..., F013
B is stored.

Next, a case where an operator operates plant equipment will be described with reference to FIG.

Here, the plant information of the plant equipment 8 is input to the operation information display means 3 by the process input means 2 via the process input unit 7. The operator
From the display screen prepared in advance, the selection display screen 34 is selected as an operation target device as shown in FIG. For example,
The high-pressure core spray system diagram of the reactor is displayed on the display screen of the CRT 11a by the operation information display means 3.

First, the operator operates the touch input device 12
The user touches the operation request information via the operation input unit 4 from the terminal a (101). The operation request information by the touch input includes a device selection as an operation target and a touch of an operation command. Here, it is assumed that a device selection as an operation target as shown in FIG. 8 is performed.

Subsequently, it is determined whether or not the touch content is a device selection. It is determined whether or not there is personal data registered because the device has been selected (102) (10).
3).

The operator operates a personal identification device, for example, FIG.
Has an IC card 19a as shown in FIG. In this embodiment, as an example of the personal identification device and the personal identification specifying unit,
A non-contact type personal identification device 20a and an IC card 19a are used. When the operator makes an operation request from the touch sensor 13a, the operator who made the operation request is identified, "OK" is displayed on the non-contact type personal identification section 20a, and the ID number. Is input to the personal data registration processing means 17.

The personal data registration processing means 17 stores the ID No. from the personal device operation information database. A search for information is performed using as a key. That is, the personal device operation information of the specified operator is sent to the device operation information determination unit 21. According to the example of FIG. When set to 1, the operator is identified as "Aoki". And
RHR “0” RCIC “1” SGTS “0” operator's personal device operation information is retrieved and sent to the device operation information determination means 21.

Next, the device database is searched (1).
04).

First, the display content of the device is specified from the touched operation request information, and the device number is specified from the display position. For example, the system number of the device is “E11”, and the device No. Is "F
In the case of “001A”, the device database search as shown in FIG. 6 is performed using the operation request information “E11” and “F001A” as keys. Then, the device touched as a result specifies the system “RHR” (10
5). Next, information matching is performed based on the information on the system of this device and the personal device operation information from the personal data registration processing means 17 (106). Then, the result is output as “0” or “1”.

For example, the system name "RHR" shown in FIG. If it is 1 “Aoki”, “0” is output in the example shown in FIG. In addition, ID No. 3 "Ogaw
If "a", "1" is output. Then, it is determined whether the input is "0" or "1" in the following procedure (107).

As a result, when it is determined to be "1", CR
At T11a, an operation command screen 35 displaying "operation command", "OFF", and "ON" as operation switches as shown in FIG. 10 is displayed. Subsequently, when the operator touches the operation command with the touch sensor 13a, the operation command is input to the device operation information processing output unit 14a via the operation input unit 4 (10).
1). Here, the content of the touch is determined, but since the operation command has been touched, the operation command creating unit 22 creates operation command data based on the touched operation target and the operation content (109).

Thus, the operation command data is output to the process output unit 10 via the operation command output means 23 (110).

On the other hand, when the device operation information determining means 21 determines "0" in step 107, or when it is determined in step 103 that there is no registered personal data, the operation is prohibited, that is, the operation is blocked ( 111). At this time, an operation prohibition command is output from the operation prohibition command section 24 to the operation information display means 3.

Then, an operation prohibition screen 36 as shown in FIG. 11 of the CRT 11a is displayed, and a message of "operation prohibition" is displayed without displaying an operation command switch. After that, it is in a state of waiting for a touch input from the next touch sensor 13a.

As described above, in this embodiment, a qualified person who operates the plant equipment and an unqualified person are separately registered as personal data for each operator. When the operator makes an operation request from the touch sensor, the operator is identified through the IC card possessed by the operator, and the personal ID is
No. Is used to search for personal device operation information, and device operation information that can be operated by the operator is output.
On the other hand, the device database is searched from the operation request information touched by the operator. As a result, the system of the touched device is specified. The device operation information processing means performs a matching between the personal device operation information and a specified device system that has been touch-input by the touch sensor. As a result, when operation permission is determined, an operation command is output to operate the plant equipment.

On the other hand, when the operation prohibition is determined, an operation prohibition command is output to prevent the operation of the plant equipment. Therefore, the operator does not operate any equipment other than the permitted plant equipment, and safe and reliable operation of the plant equipment can be realized to prevent erroneous operation of the plant equipment. In particular, safety can be ensured during trial operation of the plant or during equipment testing.

Next, a third embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG.

The difference from FIG. 1 is that personal data input means 1
5. Personal identification specifying means 16, personal data registration processing means 1

It is a point provided with. In the first and second embodiments, the personal device operation information is registered in advance in the personal data registration processing means 17 as a database. In this embodiment, the personal device operation information is registered in the storage medium 25 in advance. The storage medium 25 uses, for example, an IC card to read the personal device operation information of the IC card with, for example, a card reader as the information reading unit 26. Device operation information processing means 14
Is input by the personal device operation information and the input device,
Match with the specified device system. As a result, when the operation permission is determined, the operation command is output and the plant equipment 8 is operated.

As described above, even if the personal device operation information of the operator is registered in the IC card or the like, the operation of plant equipment other than the operator who is permitted in advance can be prevented.

The present invention is not limited to the embodiment described above, but can be implemented as follows.

First, an IC is used to specify an operator.
Although the card is used, the present invention is not limited to this, and any means capable of identifying and specifying the operator may be used. For example, palm print reading means, fingerprint reading means, voice print reading means, etc. may be used.

Secondly, in the above-described embodiment, the operation of the equipment such as the pumps is described. However, the operation is not limited to the plant equipment. For example, the operation may be performed on an automatic operation switch or a switch of a controller. The same can be applied to this.

Thirdly, in the above embodiment, the input / output between the plant equipment and the control device with respect to the plant operation device is a process input / output device. It can be applied in exactly the same way as the embodiment.

Fourth, the input device may be any device that can specify devices on the screen of the display device. For example, a pointing device such as a mouse and a light pen can be used in the same manner.
