DETAILED DESCRIPTION OF THE INVENTION
(Embodiment 1)
This embodiment is a case where the present invention is applied to a monitoring control system that can use TCP / IP-based remote object communication on a network such as an intranet.
[0025]
FIG. 1 shows the configuration of the present embodiment, and shows the main software configuration of the monitoring apps A and B installed in the monitoring control devices 5 and 6 of FIG.
[0026]
In FIG. 1, the monitoring control devices 5 and 6 form a database of transmittable extended screen component groups 11A and 11B to be displayed on the display screen of the own device, and these are stored in the transmission management unit 12A of the monitoring application A and the monitoring application B. , 12B. Here, the transmittable extended screen component is obtained by adding an interface that can be handled by the transmission / reception management units 12A and 12B to a display screen component such as a button or a display symbol in a normal screen display system.
[0027]
The transmission objects 13A and 13B transmitted by the transmission / reception management units 12A and 12B to the counterpart monitoring applications B and A are connected so that they can be referred to as the proxy transmission objects 14B and 14A in the counterpart monitoring application by remote object communication. .
[0028]
As a result, the monitoring applications A and B of the monitoring control devices 5 and 6 enable the reception management units 15A and 15B to acquire the transmittable extended screen parts of the counterpart application as the proxy transmission objects 14B and 14A. Then, the reception managers 15A and 15B copy and save the data contents of the extended screen components acquired from the counterpart monitoring applications B and A as copy extended screen component groups 16A and 16B for screens that are stored in a database in the own device. As a result, the contents of the transmittable extended screen component group on the partner side can be displayed on the display screen on the own apparatus.
[0029]
Note that once the extended screen parts are copied, depending on the type of extended screen parts, they cannot be sent directly and displayed on the other side, for example, linked directly to a bitmap resource for screen display. This is in order to avoid the presence.
[0030]
Prior to copying, the transmission management units 12A and 12B and the reception management units 15A and 15B prepare data to be copied to the transmittable extended screen component groups 11A and 11B when an acquisition request for the transmittable extended screen components is obtained.
[0031]
Further, in order to associate the transmittable extended screen component group with the acquired copy extended screen component group, the extended screen component is uniquely managed by the ID, the host information of the transmission source application, and the application type.
[0032]
Further, the copy extended screen parts are arranged on the editable screens 17A and 17B prepared on the monitoring application in order to perform dynamic acquisition and editing.
[0033]
In this way, the receiving side monitoring application acquires the extended screen part itself from the transmitting side monitoring application, and by copying the display data necessary for all copy extended screen parts associated with this extended screen part on its own device, It is not necessary to design a communication data object for each screen component, and the software structure can be simplified.
[0034]
Next, the monitoring applications A and B usually have processing functions for user events such as mouse clicks and key inputs for general screen components. Here, the monitoring applications A and B have a function of inquiring of the transmission / reception management units 12A, 12B, 15A, and 15B regarding the extended screen parts during the user event processing. As a result, the monitoring applications A and B can identify whether they are processing a user event for a sendable extended screen part or a user event process for a copy extended screen part, and a user event corresponding to the user event process. Processing can be performed.
[0035]
In other words, when a screen event is processed as a transmittable extended screen component in response to a user event occurrence, the monitoring applications A and B process the contents to be processed as usual and process them as copy extended screen components. If there is, send a sendable extended screen part corresponding to you via the send / receive management unit, and perform processing that generates an equivalent user event for the obtained sendable extended screen part. Then, the equivalent user event processing is executed in the counterpart monitoring application.
[0036]
The basic functions of the present embodiment are as described above, and the monitoring applications A and B further have the following functions with a software configuration.
[0037]
-A function that acquires a list of other screens that can be sent on the editable screen, and acquires the extended screen parts on the list, dynamically creates a copy extended screen part, and adds it to the editable screen.
[0038]
-Copying with editable screen and extended screen parts Function to edit display information such as size and color of extended screen parts.
[0039]
A function of saving the state of a copy extended screen part to a file or database, and reading from a file or database by the transmission / reception management unit and the extended screen part.
[0040]
A function for determining whether or not to allow the other extended screen part to process the user event received by the copy extended screen part by the transmission / reception management unit.
[0041]
-Monitors, developers, system administrators, etc. use templates for describing necessary functions for extended screen parts, describe program code based on template conventions, compile as a library, and then execute the application ( A function that allows an application to dynamically acquire a new part as a copy expansion screen part by placing it in a folder.
[0042]
By having these functions, it is not necessary to implement from the design again for the above-mentioned problem, and it is possible to cope with it dynamically.
[0043]
(Embodiment 2)
The present embodiment is a case where the present invention is applied to a monitoring control system in which a FireWall (firewall) is provided on a network such as the Internet.
[0044]
In FIG. 2, the monitoring control devices 5 and 6 enable communication with an external network through the firewalls 7 and 8, respectively, and protect from easy entry into the monitoring control system from the outside such as the Internet.
[0045]
In the case of this system configuration, the remote object communication used in the first embodiment cannot be used because it cannot freely exceed the firewall. On the other hand, in many cases, a firewall is set so that HTTP for referring to a Web browser can be used beyond the firewall. In response to this, a communication method called SOAP, which is a method for realizing remote object communication beyond a firewall, for converting object data into XML data and then communicating the data in a text format by HTTP. is there.
[0046]
In the present embodiment, by using SOAP in the remote object communication portion of the first embodiment, use via the Internet blocked by a firewall is also possible.
[0047]
(Embodiment 3)
This embodiment is a case where the system configuration is designed to shorten the transmission time even when the number of extended screen parts to be transmitted is large.
[0048]
In the first embodiment, as shown in FIG. 3A, the extended screen component has an interface LI that can be handled by the transmission / reception management unit for the screen component L such as a button or a display symbol in a normal screen display system. In transmission, the display information is updated by transmitting the extended screen component itself and then copying the display data to the copy extended screen component. By doing this, it is possible to simplify the software structure because it is not necessary to design both the extended screen part and the display data by designing only the extended screen part.
[0049]
However, when sending, the data structure necessary only to display the screen with the extended screen parts is also subject to transmission, and it takes time to send and the number of extended screen parts to handle increases. Has the problem that it takes too long to send.
[0050]
In order to solve this problem, in the present embodiment, the monitoring mechanisms A and B are provided with the following mechanisms.
[0051]
As shown in FIG. 3B, instead of the extended screen component, a transfer data component obtained by adding the extended screen component interface LI only to the screen component ID information LID and the transfer data LD is defined as transmission data.
[0052]
As shown in FIG. 3C, a lightweight transfer interface LIs is added to the extended screen component composed of the screen component L and the interface LI, and the display data of the extended screen component itself is copied to the transfer data component as transmission data. A function for passing to the transmission / reception unit and for transferring the transfer data component from the ID information LID to the copy expansion screen component and copying it to the display data of the copy expansion screen component when the extended screen component acquired by the transmission / reception unit is a transfer data component Define a lightweight transfer extended screen component with added functions.
[0053]
By providing such a mechanism, it is possible to transmit the extended screen parts and the lightweight transfer extended screen parts together, and when the number of parts is large, the transmission data amount can be reduced as the lightweight transfer extended screen parts to shorten the transmission time. Can do.
[0054]
Examples of the monitoring control system and the screen display information cooperation method described in the first to third embodiments will be described below.
[0055]
Example 1
The present embodiment is applied to a monitoring control system for a substation.
[0056]
(A) Creating extended screen parts
As shown in the component screen A of FIG. 4, the equipment and devices to be monitored and controlled are created as extended screen components for linking screen display information. For example, LS (disconnector), CB (breaker), bank, grounding, and their measured value display labels are created.
[0057]
In addition, if necessary, a means for enabling operations on parts of equipment that can be controlled from a general control center (such as displaying a context menu of an operation list by right-clicking the mouse on a screen part) ) Is implemented.
[0058]
(B) Creating a monitoring screen
Using the extended screen component created in (a) above, a UI (user interface) portion of the monitoring control system is created as shown in screen B of FIG. However, if it is not necessary, the extended screen parts need not be used, and may be mixed with normal parts.
[0059]
For example, a screen configuration in which an extended screen component is used in an FG (foreground, foreground) portion where the display changes and a BG (background, background) portion where the display does not change is not used.
[0060]
(C) System construction
By using the UI part created in the above (b), a monitoring control system overall screen is constructed as shown in screen C of FIG. The host information (logical address, host name, port number) of all monitoring control systems is placed as a setting file in a location that can be referenced from all substations and the general system to be linked.
[0061]
Further, if necessary, for the copy extended screen parts that are to be operated, information for permitting the operation is written in the setting file of the monitoring control apparatus having the original extended screen parts.
[0062]
(D) Expansion and removal of facilities and equipment
When facilities and equipment are added, the necessary extended screen parts are placed in the necessary parts of the UI. At this time, on the display screen on the reference side, the extended screen part is acquired from the reference source and arranged at an appropriate position on the display screen.
[0063]
When creating a new type of equipment or device, copy the parts library that contains that information to the reference side.
[0064]
When equipment or equipment is removed, the corresponding extended screen parts are deleted from the display screen. At this time, since it is invalidly displayed on the display screen on the reference side, it is deleted.
[0065]
(E) Expansion of substation
If a substation is added, proceed from (a) to (c). At this time, if there is an existing supervisory control device that needs to be referenced, the necessary extended screen parts are acquired from the newly installed substation and arranged at an appropriate position of the UI.
[0066]
As described above, according to the present embodiment, the following effects are obtained by cooperation of the screen display information.
[0067]
・ If the number of equipment and devices to be monitored and controlled increases, it is only necessary to create an extended screen component corresponding to the equipment or device and paste it on the display screen.
[0068]
・ If the number of equipment and devices to be monitored and controlled decreases, it is only necessary to delete the extended screen parts corresponding to the equipment and devices from the display screen.
[0069]
-By creating a screen that uses an extended screen component, the monitoring and control devices can be linked over the network through the extended screen component.
[0070]
-The screens of multiple monitoring and control devices can be aggregated and displayed at one location.
[0071]
In the event of an emergency of a certain monitoring and control device, it is possible to grasp the current status by acquiring the corresponding extended screen parts of that device anytime and anywhere using a network (LAN, WAN, Internet, etc.).
[0072]
(Example 2)
A present Example is a case where it applies to the monitoring control system of a water treatment plant.
[0073]
(A) Creating extended screen parts
Create equipment and devices to be monitored and controlled as extended screen components for linking screen display information. For example, an extended screen component of equipment and facilities such as a pump, a gate, a valve, and a flow meter is created. In these parts, for example, an operation / stop state, a failure state, an automatic / manual state, a power purchase / in-house state, and the like are defined as pump attributes.
[0074]
Further, controllable attributes such as the operation / stop state are set so that they can be controlled from another processing plant or the like. For example, when a pump part on the screen is specified by right-clicking the mouse, a context menu for operation and stop is displayed.
[0075]
(B) Creating a monitoring screen
A monitoring screen is constructed using the extended screen component created in (a) above. In particular, if it is not necessary to handle the part as a display part for another screen, the part created in (a) may not be used.
[0076]
For example, it creates about each facility, such as a pump well, a 1st sedimentation tank, an aeration tank, and a 2nd sedimentation tank from a trunk line. A bitmap is placed with the building frame, lines representing connections between equipment and equipment, etc. as a sketch, and parts of equipment and equipment are placed on the bitmap on the bitmap to create a monitoring screen.
[0077]
(C) System construction
A screen of the water treatment monitoring and control system is constructed using the monitoring screen created in (b) above. Create and store the host information (logical address, host name, port number) of all monitoring and control systems as a configuration file in a place that can be referenced from all processing sites and management centers. For example, put it in the management center.
[0078]
In the construction of this system, a setting file for whether or not to allow the reference monitoring application side to control the operation in the reference source monitoring application is created for each extended screen component. For example, the pump A of the treatment plant X can be controlled from the treatment plant Y but cannot be controlled from the treatment plant Z.
[0079]
(D) Expansion and removal of facilities and equipment
When facilities and equipment are added, the corresponding extended screen parts are created and placed at appropriate positions on the display screen. At this time, on the display screen on the reference side, the extended screen part is acquired from the reference source and arranged at an appropriate position on the display screen.
[0080]
When creating a new type of equipment or device, copy the parts library that contains that information to the reference side.
[0081]
When equipment or equipment is removed, the corresponding extended screen parts are deleted from the display screen. At this time, since the display is invalid on the reference-side display screen, this extended screen part is deleted.
[0082]
(E) Expansion / removal of treatment plant
When a treatment plant is added, the procedures from (a) to (c) are performed. At this time, the reference side acquires the extended screen component from the corresponding processing place and arranges it at an appropriate position on the display screen. When the processing site is removed, the extended screen parts to which it belongs are invalidly displayed on the display screen on the reference side, so these extended screen parts are deleted.
[0083]
As described above, according to the present embodiment, the same cooperation as in the first embodiment can be achieved with the water treatment plant monitoring control system in which screen display information is linked.
[0084]

By combining elements in a plurality of windows, 1 There is a problem that it cannot be made into two windows.
[0087]
In this embodiment, as shown in the system configuration example in FIG. 6, an equivalent device is realized by using a communication function using a computer (such as a personal computer or a workstation) and software such as SOAP, without using a dedicated control device. As the software for that purpose, the “screen display information linkage function” shown in the first to third embodiments is used.
[0088]

[0090]
(B) Connect another normal terminal to the computer prepared in (a) via a normal LAN, an intranet, the Internet, or the like.
[0091]
(C) As an extended screen component in the “screen display information linkage function”, a component that displays information to be shared is created. For example, text boxes, bitmaps, various symbols in the monitoring control system (pump pictures, water tanks, substation equipment, etc.).
[0092]
(D) Create an arbitrary application using the “extended screen component” created in (c).
[0093]
(E) The application created in (d) above is activated on any terminal.
[0094]
(F) On the computer 24 to which the large display 23 is connected, the application in which the “editable screen” is arranged is started, and the necessary “copy extended screen part” is arranged thereon.
[0095]
According to the above system configuration, as shown in a screen display example in FIG. 7, it is possible to match the display contents of the screens displayed on the large display 23 and the screens of the terminals 22 </ b> A to 22 </ b> N. .
[0096]
As described above, according to the present embodiment, the following system configuration is possible by cooperation of screen display information.
[0097]
-Multi-screen can be configured without dedicated hardware. Therefore, it becomes efficient in terms of both cost and space.
[0098]
-Since a normal LAN or wireless LAN can be used, the connection becomes easy.
[0099]
-It is also possible to share windows between arbitrary terminals as well as multi-screen.
