Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed system man-machine device in which a plurality of man-machine devices are connected by a transmission system.

[0002]

2. Description of the Related Art In a distributed system having a plurality of man-machine interaction controllers, CRT devices are controlled by different man-machine interaction controllers as follows.
FIG. 4 shows an example of a distributed system, which is a man-machine dialogue control device 101, a man-machine dialogue control device 102, and a calculation processing device.
Functions are distributed to 103, and each device is connected by a data way 104. Further, the man-machine interaction control device 101
CRT devices 201 and 202 and keyboards 301 and 302 are connected to the CRT device.
The T devices 203 and 204 and the keyboards 303 and 304 are connected. Generally, in the man-machine interactive function, it is common to register the points to be displayed for each function in advance in several groups. For example, in the trend graph display function, 4 points are registered per group. Assuming that there are 10 groups available, the operator is C
One of the RT devices 201 to 204 and the keyboards 301 to 304 is used to register the point that the user wants to see.

[0003]

Here, for example, a CRT is used.
When the point p is registered in the group 1 by using the device 201 and the keyboard 301, the information is stored in the man-machine interaction control device 101, and thereafter, the group 1 is changed to the CRT device 201.
When it is displayed on the screen, the state of the point p can be seen. Similarly, when displayed on the CRT device 202, since the information stored in the same man-machine interaction control device 101 is used, the state of point p can be seen. However, when it is displayed on the CRT device 203 or 204, the display information is retrieved from the man-machine interaction control device 102, and therefore the point p is not registered and is not displayed. Therefore, the operator needs to be aware of which point is registered from which CRT device, and it is necessary to store the CRT device and the man-machine interaction control device in which the point he / she wants to see is stored. There was a sexual problem. The present invention has been made to solve the above problems, and displays the same point on all CRT devices without being conscious of the CRT device and man-machine interaction control device registered by the operator except for temporary registration. It is an object of the present invention to provide a man-machine device for a distributed system that can be used.

[0004]

In order to achieve the above object, the present invention is directed to a man-machine device of a distributed system in which a plurality of man-machine devices are connected to each other by a transmission system. Transmission means for transmitting and receiving common information to and from the man-machine device, and a common storage device for storing common information related to all man-machine devices,
An individual storage device for storing individual information in each man-machine device, a selection means for deciding which information of each storage device is selected, and a function of the interactive function implementation means by the selection device are common to the distributed system. And a function selecting means for determining whether the function is an individual function only in the dialogue device.

When registering points in the man-machine dialogue function from the CRT device and the keyboard, if this is common registration information, it is sent to another man-machine dialogue control device via the transmission system to keep the registration information consistent. .. When the registration information is temporary, it is stored in only one man-machine interaction control device. Then, when the user wants to display it, he / she can input it by inputting a display request, without being aware of where it was registered.

Embodiments will be described below with reference to the drawings. Figure 1
FIG. 1 is a configuration diagram of an embodiment of a man-machine device according to the present invention. The man-machine device shown in FIG.
T device 2, keyboard 3, registration selection means 4, read selection means 5, common storage device 6, individual storage device 7, function selection switch 8, common information storage means 9, transmission means 10 and transmission system 11, each of which is provided. The functions are as shown below.
First, the dialogue function realizing means 1 inputs a dialogue request item of an operator via the keyboard 3, displays the result of the dialogue function requested here on the CRT device 2, and the function selection switch 8 Selection of whether items input from the keyboard 3 are commonly stored in all man-machine interaction control devices or individually stored in the own device and the keyboard 3
When there is a display request from the common function 81 and the individual function 82, it is possible to select “common function” to display the commonly stored items or “individual function” to display the individually stored items. It is composed of two switches. Therefore, when the "common function" is selected, the common function switch is pressed, and when the "individual function" is selected, the function type of the man-machine interactive control device is selected by pressing the individual function switch.

The registration selecting means 4 inputs the registration information from the interactive function realizing means 1 and the function type from the function selecting switch 8. If the function type is a common function, the registration information is stored in the common information storing means 9. Output. If the function type is the individual function, the registration information is stored in the individual storage device 7. Further, the common information storage means 9 stores the registration information input from the registration selection means 4 in the common storage device 6 and also transmits the registration information input this time to another man-machine interaction control device. The registration information is passed to 10, and the transmission means 10 receiving this passes the registration information to another man-machine dialogue control device via the transmission system 11. Also, transmission means
When the other man-machine dialogue control device 10 has registration information of the common function, 10 receives the registration information via the transmission system 11 and makes a registration request to its own common information storage means 9. The common information storage means 9 stores the registration information in the common storage device 6 in the same manner as the request from the registration selection means 4.

When there is a display request from the keyboard 3, the interactive function realizing means 1 requests the read selecting means 5 to read the registration information necessary for displaying on the CRT device 2. FIG. 3 is a specific example of the interactive function, and shows an example in which a trend graph display screen is displayed on the CRT device. In order to realize the trend graph display interactive function in the figure, the input point number and the display range of the curve display area (0 to 100 ° C
Etc.) must be stored. In the following description, the registration item information input from the keyboard 3 to realize the interactive function will be referred to as "registration information". In FIG. 1, the dialogue function realizing means 1 inputs registration information of a dialogue request from the keyboard 3 and outputs the registration request of the registration information to the registration selecting means 4.

Next, the operation will be described. Read selection means 5
Inputs the registration information read request from the interactive function realizing means 1 and the function type from the function selection switch 8. If the function type is a common function, the registration information corresponding to the read request is retrieved from the common storage device 6, If the function type is the individual function, the registration information corresponding to the read request is retrieved from the individual storage device 7, the registration information is output to the interactive function realizing means 1, and the interactive function realizing means 1 displays it on the CRT device 2.

Next, an example of a place where two man-machine interaction control devices exist in the distributed system will be specifically described with reference to FIG. The two man-machine dialogue control devices are shown in FIG.
The configuration is the same as that shown in FIG. 2, and one of the two is described as A and the other is described as B. On the man-machine dialogue control unit A side, after selecting "common function" with the function selection switch 8-A, the keyboard 3-A and the CRT device 2-A are selected.
Request to register the following items from the trend graph display function. Registration requested item …… Registration destination group number 1 Point to register 4B000 (0 to 3000 rpm) Point to register 4D000 (0 to 10 MW) Point to register 4C000 (0 to 100 ℃) Assuming that the registration information A is the registration information A, the registration information A is registered via the interactive function realizing means 1-A through the registration selecting means 4-A.
Registered selection means 4-A is the function selection switch 8-
Since the status of A is read and the status is "common function", the registration information A is sent to the common information storage means 9-A. The common information storage means 9-A stores 4B000, 4D000, 4C000 in the area for storing the registered information A in the common storage device 6-A for storing the items registered in the group 1 of the trend graph display function. Further, since the common information storage means 9-A transmits the registration information A to the man-machine dialogue control apparatus B, the common information storage means 9-A transfers the registration information A to the transmission means 10-A.
To send. The transmission means 10-A transmits from the transmission system 11-A to the transmission system 11-B of the man-machine dialogue control apparatus B.

On the other hand, the transmission system 11-B transfers the received registration information A to the transmission means 10-B. The transmission means 10-B judges that the received content is a common information registration request, sends the received registration information A to the common information storage means 9-B, and the common information storage means 9-B is the common storage device. 4B is displayed in the area for storing the items registered in group 1 of the 6-B trend graph display function.
Memorize 000, 4D000, 4C000. As a result, the contents stored in the common storage device 6-A and the common storage device 6-B become the same. Therefore, if the request to display the trend graph display function group 1 is made from the keyboard 3-A or 3-B after the function selection switches 8-A and 8-B have selected the "common function" side, the interactive function realization means A request is sent to the read selection means 5-A or 5-B via 1-A or 1-B, and the function selection switch 8-A
Or, because 8-B is selecting "common function", read selection means 5
-A or 5-B retrieves the currently registered information from the common storage device 6-A or 6-B. 4B000 in the group 1 area of the trend graph display function of the common storage device 6-A or 6-B
, 4D000, 4C000 are registered, and the registration information is sent to the interactive function realizing means 1-A or 1-B, and the CRT device 2-
Displayed in A or 2-B. As described above, the registration information A registered from the man-machine dialogue control device A is displayed in the man-machine dialogue control device B in exactly the same manner.

On the other hand, in the normal man-machine function, in addition to the case where the operator wants to see the data of the same point from all CRT devices as described above, the operator himself may want to see the data of a specific point temporarily. Occur. An example of this case will be described below. Man-machine dialogue control device A
After selecting "individual function" with the function selection switch 8-A, the keyboard 3-A and the CRT device 2-A request the trend graph display function to register the following items. Item requested to be registered …… Group number of registration destination 1 Point to register 4B001 (0 to 3000 rpm) Point to register 4D001 (0 to 10 MW) Point to register 4C001 (0 to 100 ° C) If the registration information A ′ is used, the registration information A ′ is stored in the registration selecting means via the interactive function realizing means 1-A.
The registration selection means 4-A reads in the status of the function selection switch 8-A, and the status is "individual function", so that the registration information A'is registered in the trend of the individual storage device 7-A. 4B001, 4D001, and 4C001 are stored in the area that stores the items registered in group 1 of the graph display function. At this time, since the registration information A'is not passed to the common information storage means 9-A, it is not stored in the man-machine dialogue control device B side. As a result, different points can be registered on the man-machine interaction control device A side and the man-machine interaction control device B side.

Also, the function selection switch 8-A is set to "individual function".
If the display request for the group 1 of the trend graph display function is made from the keyboards 3-A and 3-B after selecting, the request is sent to the read selection means 5-A via the interactive function realizing means 1-A. Since the function selection switch 8-A is selecting the "individual function", the read selection means 5-A retrieves the currently registered information from the individual storage device 7-A. Individual storage device 7-A
In the area of the group 1 of the trend graph display function of
001, 4D001 and 4C001 are registered, and the registration information is sent to the interactive function realizing means 1-A and displayed on the CRT device 2-A. As described above, if the "individual function" is selected by the function selection switch 8, different points can be registered in the man-machine interaction control device A and the man-machine interaction control device B and can be displayed separately.

[0013]

As described above, according to the present invention, the points to be registered in the man-machine function are commonly stored in a plurality of man-machine interaction control devices. All CRs are stored in the man-machine device side without being aware of whether or not
It can be displayed on the T device, which reduces the burden on the operator when using the dialogue device. Also, depending on the selection, when temporarily registering points, it is stored only in its own man-machine interaction control device and does not affect other man-machine interaction control devices, improving operability. ..
