Description

  The present invention relates to a technology related to a computer human interface, and relates to an information linkage window system related to various information display screens as a production management and manufacturing management system in the manufacturing industry and other business portals.

  In recent years, with the advancement of computer hardware and software, the computer display screen has become high definition and the number of display pixels has improved, so that it is possible to open multiple windows on one screen, and there is an independent program for each window. It has come to be able to perform each function. In such a window system, there is a case where it is desired to pass data between windows (that is, between programs). As a system for realizing data transfer between windows, for example, there is an information cooperation window system disclosed in Patent Document 1.

  As shown in FIG. 4, the information linkage window system includes a window 401 that displays a plant configuration and a window 402 that displays a trend (history) of process variables in a screen 400. In this window system, each step of the target process is indicated by an icon in the window 401. For example, by operating the mouse as a pointing device, the pointer on the screen 400 is overlapped with any icon to select a corresponding object, and this object is moved to the window 402 as indicated by an arrow line 403, so-called As a result of the drag-and-drop operation, a transition history (trend) of the process variable belonging to the process of the selected object is displayed in the window 402.

  By the drag and drop operation described above, in the information linkage window system, the process variable name belonging to the selected object is transferred to the program displaying the window 402. By passing the above-described information corresponding to the drag and drop operation, the corresponding program collects the corresponding process variables and displays the trend in the window 402.

  In addition, as a term of operation of a pointing device such as a mouse, “select” is to press a button in a certain object area, “drag” is to subtract while holding down the button, and “drop” is a certain screen area. Generally, it means that you release the button.

  By the way, in the information linkage window system described above, when data is transferred between windows, the data used for the previous display is rewritten (overwritten) with the newly transferred data. For this reason, there has been a problem that it is not possible to compare trends of two or more data, such as comparison of previous data and subsequent data in time series, comparison of different process variables in the same time series.

  The present invention has been made to solve the above-described problems, and an object thereof is to display a plurality of data delivered between windows.

  An information linkage window system according to the present invention sends attribute data when an object arranged in the first window with attribute data described in a meta language is selected and dragged by a pointing device, and is sent to an attribute data storage unit. Drag processing execution means for storing the data, and data processing means for extracting attribute data stored in the sending attribute data storage unit and displaying the screen in the second window when the object is dropped on the second window by the pointing device The data processing means appends new attribute data to the receiving attribute data storage unit in which the attribute data is already stored, extracts the attribute data stored in the receiving attribute data storage unit, and extracts the second window. Display the screen.

  In the information linkage window system, the data processing means may erase the attribute data having the oldest stored time when the amount of attribute data that can be stored is exceeded in the receiving attribute data storage unit. . The data processing means may be provided with attribute data removing means for accepting a user's operation and erasing the attribute data selected and designated by the operation from the received attribute data storage unit.

  As described above, according to the present invention, the data processing means appends new attribute data to the receiving attribute data storage unit in which the attribute data is already stored, and stores the new attribute data in the receiving attribute data storage unit. Since all the attribute data is extracted and displayed on the second window, an excellent effect that a plurality of data delivered between the windows can be additionally displayed is obtained.

FIG. 2 is a flowchart for explaining an operation example of the information cooperation window system in the embodiment of the present invention. FIG. 3 is an explanatory diagram illustrating an example of a display screen of the information cooperation window system according to the embodiment of the present invention. FIG. 4 is an explanatory diagram illustrating an example of a display screen of the information cooperation window system.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing the configuration of the information linkage window system in the embodiment of the present invention. This information linkage window system includes an operation detection unit 101, an operation determination unit 102, a drag processing execution unit 103, a feed attribute data storage unit 104, a data processing unit 105, a receiving attribute data storage unit 106, a pointing device 107, a keyboard 108, and A display unit 109 is provided.

  The operation detection unit 101 detects an operation of the pointing device 107 by the user. The operation determination unit 102 determines each operation such as an object drag operation and a drop operation on the display screen (first window) using the pointing device 107. The drag processing execution unit 103 stores the attribute data of the drag source object in the sending attribute data storage unit 104 when a drag operation is performed. The attribute data has a data structure defined by a meta language. The sending attribute data storage unit 104 includes files, modules, etc. that can be used between programs and have a shared property. On the other hand, the receiving attribute data storage unit 106 may be internal data of a receiving program related to the data processing unit.

  For example, object attribute data includes point parameter information, data collection destination information, date and time information, search condition information, event related information, information on collected data, reference information to the drag / drop target object, and other information. There is.

  The information regarding the point parameter indicates the parameter of the point when the object is an object corresponding to the monitoring point of the process (for example, an object representing a device or a monitoring point in the process configuration diagram). Information about the point parameter includes item ID (monitoring point number, etc.), point name, range upper limit, range lower limit, engineering unit, full path, descriptor, delimiter, menu character string at drop, data type, and the like.

  The data collection destination information indicates a collection destination of collected data such as process variables. The data collection destination information includes a connection destination application server name, a data collection engine name, an identifier for the data collection engine (program), and object reference information for the data collection engine. The date / time information indicates, for example, the date / time when the alarm occurred in the point process variable. The date information includes occurrence date information, start date information, end date information, and the like.

  The search condition information indicates a condition for searching collected data such as process variables. Search condition information includes time span, time interval, maximum number of records, time base, time offset, time shift, search mode, and the like. The event related information indicates an event (for example, pointing device operation or alarm occurrence) related to the object. The event related information includes a unit name and an event name.

  Information related to collected data includes a lot ID and actual data. Reference information to the drag / drop target object includes a drag source object name, a drop destination object name, and the like. Other information includes an arbitrary character string group, an arbitrary data set, an arbitrary object group, and the like.

  The data processing unit 105 executes the application program and stores it in the sending attribute data storage unit 104 according to the program of the drop destination window when a drop operation is performed on another window (second window) on the display screen. The attribute data being processed. The data processing unit 105 extracts the attribute data stored in the sending attribute data storage unit 104 and performs screen display on the corresponding window (second window).

  Next, the operation of the information cooperation window system in this embodiment will be described. As shown in the flowchart of FIG. 2, when the operation detection unit 101 detects a user operation on the pointing device 107 such as a mouse in step S201, the operation determination unit 102 starts determining the operation. When the operation determination unit 102 determines an object drag operation (Y in step S202), the drag processing execution unit 103 stores (stores) the attribute data of the drag source object in the sending attribute data storage unit 104 (step S203). ).

  For example, when the operation determination unit 102 recognizes from the detection result of the operation detection unit 101 that the cursor of the pointing device 107 indicates a selectable object on the screen and the button of the pointing device 107 is pressed, It is determined that this object has been selected. Next, when an object is selected, the operation determination unit 102 stores the current position of the cursor of the pointing device 107 on the screen, and then the cursor is held while the button of the pointing device 107 is pressed by a user operation. Detect that has moved. By this detection, the amount of positional deviation on the screen from the stored cursor position is detected. When the amount of positional deviation of the cursor is equal to or greater than a predetermined threshold value, the operation determination unit 102 starts dragging. Judged as a thing (drag operation). Whether or not the target object is selectable can be confirmed by referring to attribute data set in advance in the program of each object.

  Thereafter, when the operation determination unit 102 determines an object drop operation (Y in step S204), the data processing unit 105 is stored in the feed attribute data storage unit 104 in accordance with each program of the plurality of drop destination objects. The attribute data being processed is processed (step S205).

  For example, when the cursor indicates a selectable object on the screen and detects that the selection state by the pointing device 107 has been released, the operation determination unit 102 determines that the object has been dropped. Further, the data processing unit 105 considers the types of the drag source object and the drop destination object from which the attribute information stored in the feed attribute data storage unit 104 is extracted, and extracts necessary data from the extracted attribute data. Select and execute processing according to the drag source object and drop destination object. As a result of this processing, a trend or the like is displayed on the display unit 109 (step S206).

  On the other hand, when the drop operation is not detected within the time set in step S204, the attribute data stored in the previous attribute data storage unit 104 is deleted (step S207).

  The above-described operation is repeated until an end instruction is input (step S208). When the end instruction is input, the attribute data stored in the feed attribute data storage unit 104 is deleted (step S209), and the process ends. To do.

  Here, according to the present embodiment, the data processing unit 105 appends new attribute data to the receiving attribute data storage unit 106 in which the attribute data has already been stored, and therefore, by repeating steps S201 to S206. A plurality of attribute data is stored (added) in the received attribute data storage unit 106. Since the data processing unit 105 extracts all the attribute data stored in the receiving attribute data storage unit 106 and performs screen display, the corresponding window (second window) of the display unit 109 includes Multiple trends will be displayed. As a result, according to the present embodiment, it is possible to compare two or more data trends, such as comparing the previous data and the subsequent data in time series, comparing different process variables in the same time series. become able to.

  Hereinafter, an example will be described in more detail. First, attribute data will be described. The attribute data has a data structure that does not depend on the program that displays the screen, and each program sets and decodes only necessary portions according to the specifications, and further executes display. The sender program transmits data without being aware of the receiver program, while the receiver program receives data without being aware of the sender program. For this purpose, a feed attribute data storage unit 104 is provided as an information transmission means between programs, and receives information from the feed attribute data storage unit 104 and stores it additionally in the attribute data storage unit 106. Also, after necessary and common parts are decoded, they are displayed on the screen.

  In order to realize this, the attribute data is defined in a meta language. The meta language is a language for describing a language, such as HTML or C language for describing a Web page. Further, XML (eXten simple Markup Language) that is an extension of HTML can be mentioned. The meta language has a basic structure defined, and the structure can be freely determined within the scope of this definition.

  Hereinafter, the case where XML is used as attribute data as a meta language will be described. An XML element is a unit of information that starts with <element name> and ends with </ element name>. The element name can be freely determined by the program. An element having no content is indicated by <element name />.

  For example, as shown in FIG. 3, an example is shown in which a window of a system diagram screen 301 in which a system diagram is shown as a graphic and a trend screen 302 in which process variables are displayed is displayed on the screen 300. To do. On the system diagram screen 301, for example, an object 311 that can be selected as a graphic part indicating a distillation column is shown.

  Here, the object 311 has attribute data described (defined) in XML as shown below.

--- Definition 1 ---
<Equipment name>
<Area name> A </ Area name>
<Device name> Distillation tower A102 <// Device name>
<Lot name> Material input batch process </ Lot name>
<Time> 2009/12/28 11:25 </ Time>
<Monitoring point>
<Point name> A102-FLOW. PV </ Point name>
<Point name> A102-TEMP1. PV </ Point name>
<Point name> A102-LEVEL. PV </ Point name>
<Point name> A102-TEMP2. PV </ Point name>
</ Monitoring point>
</ Equipment name>

  On the other hand, on the trend screen 302, the processable attribute data is defined in XML as shown below. The pen number n is 8, for example. When n = 8, eight points can be displayed on the trend screen 302.

--- Definition 2 ----
<Energy usage trend>

-------------------

  Here, when an object 311 (distillation tower) in the system diagram screen 301 is selected and dragged with a pointing device such as a mouse, the attribute data indicated by definition 1 is stored in the feed attribute data storage unit 104. Thereafter, when the dragged object 311 is dropped on the trend screen 302 so as to display a history graph of process variables belonging to the object 311 (arrow line 303), the definition 1 stored in the feed attribute data storage unit 104 is displayed. Is acquired by the receiver program operating in the trend screen 302 window.

  In the receiver program, the <point name> defined in definition 2 among the attribute data acquired from the feed attribute data storage unit 104 can be understood as a common element name definition. And the trend screen 302 operates to display the trend at the current time. At this time, the received attribute data storage unit 106 stores the four <point name>.

  Next, as described above, when an additional object 312 (tank) in the system diagram screen 301 is selected and dragged with the pointing device, new attribute data (point name, etc.) indicated by the same definition 1 ′ is displayed. <Point name> relating to the current object 312 is stored (added) in the sending attribute data storage unit 104. Thereafter, when the dragged object 312 is dropped on the trend screen 302 (arrow line 304), it is indicated by the definition 1 ′ stored in the feed attribute data storage unit 104 by the receiver program operating on the trend screen 302. The attribute data thus added is further added to the receiving attribute data storage unit 106.

  In the receiver program, for each of the two attribute data groups stored in the receiver attribute data storage unit 106, <point name> defined in definition 2 is defined as a common element name definition, and the point name of each attribute data is a trend. Are sequentially assigned to the display pens 1 to 8, and the trend screen 302 displays the trend at the current time. As a result, eight trend graphs are displayed on the trend screen 302 as point data relating to the distillation column and the tank.

  In this way, the logical name between <element name> </ element name> is exchanged between screen programs. In the sender program on the system diagram screen 301, XML (attribute data) defined in the object is stored in the feed attribute data storage unit 104, and in the receiver program on the trend screen 302, it is stored in the feed attribute data storage unit 104. By extracting only the logical name common to both in the receiving attribute data storage unit 106 from the stored XML and storing it in the receiving attribute data storage unit 106, display according to the designation is executed, and data other than the designated one is stored. ignore.

  Here, the information cooperation window system of the above-described embodiment can be realized by a computer having a CPU, a storage device, and an interface with the outside, and a program for controlling these hardware resources. In such a computer, the information link window program of the present invention is provided in a state of being recorded on a recording medium such as a flexible disk, a CD-ROM, a DVD-ROM, or a memory card. The CPU writes the program read from the recording medium into the storage device, and executes the processing described in this embodiment according to the program.

  It should be noted that the present invention is not limited to the embodiment described above, and that many modifications can be implemented by those having ordinary knowledge in the art within the technical idea of the present invention. It is obvious.

  For example, in the receiving attribute data storage unit, the amount of attribute data that can be stored is set, and when new attribute data is stored exceeding the set amount of attribute data that can be stored, the received attribute data is stored. New attribute data may be stored by deleting the attribute data having the oldest time. In addition, an attribute data removing unit may be provided that receives a user's operation using a toolbar on the receiver's window and deletes the attribute data selected and instructed by this operation from the receiving attribute data storage unit.
