Description

Drawing assistance device, display system, and drawing assistance method

Technical Field

The present invention relates to a drawing support device, a display system, and a drawing support method for supporting drawing using existing screen data.

Background

The programmable display is generally connected to devices such as a programmable Logic controller (hereinafter referred to as a plc), a sensor, a drive device, and an input/output device, and is used for displaying states of the devices and operating the devices.

In recent years, there has been an increasing demand for displaying the state of a device not only by a programmable display but also by a display device such as an ann lamp (Andon), a large monitor, and a portable terminal. The "on" lamp is a display device used in a production site to notify a production state.

In response to these demands, screen display in a display device such as a downlight, a large monitor, or a portable terminal is considered to be realized using screen data created for a programmable display. However, since these display devices and programmable displays generally have different screen sizes, some changes are made to screen data created for the programmable displays.

On the other hand, if screen data corresponding to various screen sizes are generated in advance, it is necessary to secure a memory capacity in order to store the screen data. Patent document 1 discloses a drawing support system capable of generating screen data corresponding to various screen sizes while suppressing the memory capacity. The drawing support system described in patent document 1 converts screen data into relative information screen data composed of relative arrangement information with respect to an arbitrary screen, thereby suppressing the memory capacity.

Disclosure of Invention

In the technique described in patent document 1, the same screen is converted into screen data corresponding to each screen size so that the same screen can be displayed on displays of various screen sizes in accordance with the screen size. In the technique described in patent document 1, although the plurality of assumed displays are different in screen size, the types are single, that is, all are programmable displays, and therefore, there is no problem in displaying the same screen as described above. On the other hand, in the case of a display device other than the programmable display, for example, a display device such as a downlight, a large monitor, and a mobile terminal, it is considered that display of a screen which is not exactly the same as that of the programmable display is desired. For example, a request is made to display the screen on the programmable display device with additional information included therein, or to display the screen with a part of the screen deleted from the screen displayed on the programmable display device. In the case described above, it is desirable to be able to display existing screen data on a screen having a size different from the size of the screen determined according to the screen size. However, in the technique described in patent document 1, since the existing screen data is directly converted into the screen data corresponding to each screen size, there is a problem that the screen data needs to be rearranged when information is added or deleted to the converted screen data.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a drawing support apparatus capable of easily changing the size of screen data to be used when creating a display screen by using existing screen data.

In order to solve the above-described problem and achieve the object, a drawing support device according to the present invention includes a storage unit that stores 1 st screen data that is screen data of a1 st screen. The drawing assistance device includes: a calling unit which uses the 1 st screen data stored in the storage unit to configure a calling image, which is at least a part of the 1 st screen, in the 2 nd screen; and an adjusting unit that adjusts the size of the calling image.

ADVANTAGEOUS EFFECTS OF INVENTION

The drawing support device according to the present invention has an effect that, when creating a display screen by following existing screen data, the size of the screen data to be followed can be easily changed.

Detailed Description

The drawing support device, the display system, and the drawing support method according to the embodiments of the present invention will be described in detail below with reference to the drawings. The present invention is not limited to the embodiments.

Provided is an implementation mode.

Fig. 1 is a diagram showing a configuration example of a display system according to an embodiment of the present invention. The display system 5 according to the embodiment includes: drawing auxiliary device 1, display 2 and terminal 3. The display 2 is connectable with an external device 4. In fig. 1, an example of connection of the display 2 to the external device 4 is shown.

The external device 4 is a device such as a PLC, a sensor, a driving device, and an input/output device. The display 2 is a programmable display, and displays the state of the external device 4. In addition, the display 2 receives an operation for the external device 4 from the user. The drawing support device 1 is a device that supports creation of a screen displayed on the display 2 and can store screen data that is data representing the created screen. The drawing support device 1 according to the present embodiment can generate screen data that can be displayed on the terminal 3 using screen data that is screen data created for the display 2. Hereinafter, the data of the 1 st screen created for the display 2 is referred to as existing screen data or 1 st screen data. Note that, although an example in which the display 2 of the present embodiment is a programmable display is described, the display 2 is not limited to a programmable display as long as it is a display corresponding to existing screen data.

The terminal 3 is a terminal having a function of communicating with a display unit such as a display or a monitor. The terminal 3 is for example a security light, a large monitor, a smart phone or a tablet. In fig. 1, 1 terminal 3 is illustrated, but a plurality of terminals 3 may be provided. In addition, when the display system 5 includes a plurality of terminals 3, the plurality of terminals 3 may be configured by devices of different types. For example, a smartphone, an amp, and a large monitor may be mixed as the plurality of terminals 3. In the present embodiment, the terminal 3 can display a screen obtained by using at least a part of existing screen data created for the display 2.

The drawing support device 1 according to the present embodiment can arrange at least a part of existing screen data in a new screen being created when creating screen data of the new screen. As described above, the case where existing screen data is arranged in a new screen is referred to as a screen call. The user can also use the drawing support apparatus 1 to place the existing screen data on the new screen and place another drawing object on the new screen by screen call.

On the other hand, the screen data called by the screen call is usually arranged in a fixed size in the new screen. The screen call is generally used in creation of a new screen for the display 2, and is thus an appropriate size in the display 2. However, the screen size of the terminal 3 is usually different from the screen size of the display 2. In addition, in the case of being displayed on the terminal 3, the application may be different from that in the case of being displayed on the display 2, and the size of the screen that the user desires to display on the terminal 3 is not necessarily the same as the size of the screen displayed on the display 2. The drawing support apparatus 1 according to the present embodiment receives a change in the size of screen data called by a screen call. Thus, the drawing support apparatus 1 can easily change the size of the existing screen data to be displayed when creating a new screen for display on the terminal 3 using the existing screen data.

In addition, in a case where screen data for the terminal 3 is created by following a part of existing screen data in a general drawing support device, screen data in which a necessary part is extracted from the existing screen data is generated, and the generated screen data is arranged by screen calling. In contrast, the drawing support apparatus 1 according to the present embodiment can perform placement on a newly created screen in units of objects placed in the called-up screen data. This allows the user to easily create a screen that continues to use a part of the existing screen data. Next, the configuration and operation of each component constituting the display system 5 of the present embodiment will be described in detail.

As shown in fig. 1, the drawing assistance device 1 includes: communication unit 11, operation unit 12, storage unit 13, display unit 14, and input unit 15. The communication unit 11 communicates with a communication unit 21 of the display 2 described later. The communication performed between the communication unit 11 and the communication unit 21 may be wired communication or wireless communication. The arithmetic unit 12 performs arithmetic operations in the drawing support apparatus 1. Specifically, the arithmetic unit 12 executes processing including the drawing support processing according to the present embodiment. The details of the calculation unit 12 will be described later. The storage unit 13 stores image information, which is a set of screen data generated by the arithmetic unit 12. That is, the storage unit 13 stores screen information including the 1 st screen data which is screen data for the display 2. The display unit 14 displays image data represented by screen data in accordance with an instruction from the arithmetic unit 12. The display unit 14 is exemplified by a monitor and a monitor. The input unit 15 receives an input from a user and outputs the received information to the arithmetic unit 12. The input unit 15 is exemplified by a keyboard and a mouse. The display unit 14 and the input unit 15 may be integrated, and the display unit 14 and the input unit 15 may be implemented by a touch panel or the like.

Fig. 2 is a diagram showing a configuration example of the arithmetic unit 12 of the drawing support apparatus 1. The arithmetic unit 12 includes a drawing support processing unit 121 that performs drawing support processing. The drawing support processing unit 121 includes: a creation unit 122, a calling unit 123, an adjustment unit 124, and a data generation unit 125. The creation unit 122 creates screen data to be displayed on a device having a display unit, such as the display 2 or the terminal 3. The calling unit 123 controls the screen call. That is, the calling unit 123 uses the 1 st screen data stored in the storage unit 13 to arrange the calling image, which is at least a part of the 1 st screen, in the 2 nd screen, which is the new creation screen. The call image is an image arranged on the created screen, and is the entire or a part of the 1 st screen, which is the existing screen data. The adjusting unit 124 adjusts the size of the call image, which is at least a part of the screen called by the screen call. The data generation unit 125 adds call information, which is information relating to the called screen, to the screen data.

Returning to the explanation using fig. 1, as shown in fig. 1, the display 2 includes: communication unit 21, calculation unit 22, storage unit 23, display unit 24, and input unit 25. The communication unit 21 communicates with the communication unit 11 of the drawing support apparatus 1 and the communication unit 31 of the terminal 3 described later. The communication performed between the communication unit 21 and the communication unit 31 may be wired communication or wireless communication. The communication performed between the communication unit 21 and the communication unit 11 and the communication performed between the communication unit 21 and the communication unit 31 may be communication of the same communication method or communication of different communication methods.

The arithmetic unit 22 performs arithmetic operations on the display 2. More specifically, the calculation unit 22 performs a process of displaying screen data received from the drawing support apparatus 1 via the communication unit 21 on the display unit 24 or performing a calculation based on information input by the user received via the input unit 25. Further, upon receiving a request for acquiring screen information from the terminal 3 via the communication unit 21, the operation unit 22 reads the screen information from the storage unit 23 and transmits the screen information to the terminal 3 via the communication unit 21. For example, the arithmetic unit 22 has a Web (Web page) server function, and causes the terminal 3 to download screen information by the Web server function. The arithmetic unit 22 acquires information indicating the state of the external device 4 from the external device 4, and reflects the acquired information on the screen data displayed on the display unit 24. The storage unit 23 stores screen information received from the drawing support apparatus 1 via the communication unit 21. The display unit 24 displays the screen data in accordance with an instruction from the arithmetic unit 22. The display unit 24 is exemplified by a monitor and a monitor. The input unit 25 receives an input from a user and outputs the received information to the arithmetic unit 22. The input unit 25 is exemplified by a keyboard and a mouse. The display unit 24 and the input unit 25 may be integrated, and the display unit 24 and the input unit 25 may be implemented by a touch panel or the like.

As shown in fig. 1, the terminal 3 includes: a communication unit 31, an arithmetic unit 32, a storage unit 33, a display unit 34, and an input unit 35. The communication unit 31 communicates with the communication unit 21 of the display 2. The arithmetic unit 32 executes an arithmetic operation in the terminal 3. The details of the calculation unit 32 will be described later. Specifically, for example, the arithmetic unit 32 displays screen data received from the display 2 via the communication unit 31 on the display unit 34. The display unit 34 displays the screen data in accordance with an instruction from the arithmetic unit 32. The display unit 34 is exemplified by a monitor and a monitor. The input unit 35 receives an input from a user and outputs the received information to the arithmetic unit 32. The input unit 35 is exemplified by a keyboard and a mouse. The display unit 34 and the input unit 35 may be integrated, and the display unit 34 and the input unit 35 may be implemented by a touch panel or the like.

Fig. 3 is a diagram showing a configuration example of the operation unit 32 of the terminal 3. The calculation unit 32 includes a display processing unit 321 that performs the display processing of the present embodiment. The display processing unit 321 includes an acquisition unit 322 and a display control unit 323. The acquisition unit 322 acquires the screen information stored in the storage unit 23 of the display 2 via the communication unit 31 and stores the screen information in the storage unit 33. When the display 2 has a Web server function, the acquisition unit 322 is realized by a function of a part of a browser. The user operates the input unit 35 of the terminal 3 to download screen information from the display 2. The display control unit 323 reads screen data to be displayed from the screen information stored in the storage unit 33, adjusts the call screen using the call screen information added to the screen data, and displays the screen data.

Next, the hardware configuration of the above-described arithmetic unit 12, arithmetic unit 22, and arithmetic unit 32 will be described. The operation unit 12, the operation unit 22, and the operation unit 32 are processing circuits. The processing circuit may be a control circuit having a processor or may be dedicated hardware. Fig. 4 is a diagram showing a configuration example of the control circuit. When the processing circuit is a control circuit, the control circuit is, for example, the control circuit 900 having the configuration shown in fig. 4.

The control circuit 900 has a processor 901 and a memory 902. The processor 901 is a CPU (Central Processing Unit, also referred to as a Central Processing Unit), a Processing Unit, an arithmetic Unit, a microprocessor, a microcomputer, a processor, a dsp (digital Signal processor), or the like. The memory 902 is, for example, a nonvolatile or volatile semiconductor memory such as a ram (random Access memory), a rom (read Only memory), or a flash memory, or a magnetic disk.

When the processing circuit is the control circuit 900 having a processor, the

arithmetic units

12, 22, and 32 are realized by the processor 901 reading out and executing a program describing processing of each unit stored in the memory 902. In addition, the memory 902 also serves as a temporary memory in each process implemented by the processor 901.

In the case where the processing circuit is dedicated hardware, the processing circuit is, for example, an asic (application Specific Integrated circuit), an fpga (field Programmable Gate array), or a combination thereof.

Next, the operation of the present embodiment will be explained. Fig. 5 is a diagram showing an example of screen information including screen data created by the drawing support apparatus 1 according to the present embodiment. The screen information is stored in the storage unit 13 of the drawing support apparatus 1 as described above. Fig. 5 shows a state in which n screens of screen 1 to screen n (n is an integer greater than or equal to 1) have been created by the user. The picture information includes picture attribute information 7 which is attribute information of each picture. The screen data corresponding to 1 screen includes screen attribute information 7 and object information, which is information on each object disposed on the screen. In fig. 5, for example, the screen data 6 corresponding to the screen 1 includes the screen attribute information 61 and the object information group 62 which is a set of object information. The screen attribute information 61 includes "screen 1" as information for identifying a screen, and includes attribute information of the screen 1. In the example shown in FIG. 5, m objects to be placed on screen 1 are AAA 1-1 to AAA 1-m (m is an integer of 1 or more). Therefore, the object information group 62 contains object information corresponding to each of the m objects. The object information includes the type and identification information of the object and attribute information of the object. AAA 1-1 is the type and identification information of each object. AAA is information indicating the type of object, and numerical values and symbols such as 1-1 and 1-m after AAA indicate the number indicating the screen and the number of the object of the same type in the same screen. For example, AAA 1-1 is the object of the 1 st AAA category of panel 1, AAA 1-m is the object of the m-th AAA category of panel 1, AAA 2-1 is the object of the 1 st AAA category of panel 2. The other screen data constituting the screen information has the same configuration as the screen data 6, but the contents and the number of objects of the attribute information are determined in accordance with the screen. Objects of various categories are generated in advance as images. For example, when the type of the object is a meter, an image of the meter is generated in advance as the object. The image information includes the image data of each object generated in advance. Alternatively, the object information of the screen data may include image data corresponding to each object.

Each screen data constituting the screen information is created by the creation unit 122. The creation unit 122 generates screen data of a screen to be displayed on the display 2 based on an operation received from the user. The method of generating screen data for a screen to be displayed on the display 2 is not particularly limited, and a general method can be used. For example, if the creation unit 122 receives an instruction to start creation of screen data via the input unit 25, it displays a new creation screen for creating a blank state on the display unit 24. The creation unit 122 displays a list of objects that can be selected on the display unit 24, for example, and the user selects the objects via the input unit 25 and arranges the objects in order on a creation screen for new creation. Thereby, the object is arranged to the screen for new creation. If the object is placed on the screen and a save instruction is input via the input unit 25, the creation unit 122 stores data indicating the screen on which the object is placed as screen data in the storage unit 13.

Next, creation of a screen for displaying to the terminal 3 of the present embodiment will be described. Fig. 6 is a flowchart showing an example of a flow of a screen creation process for displaying the screen to the terminal 3 according to the embodiment. The processing shown in fig. 6 is started if an instruction to start creation of a screen to be displayed on the terminal 3 is input via the input unit 15. The creation unit 122 first displays a creation screen for creating a new screen on the display unit 14 (step S1). Fig. 7 is a diagram showing an example of a state in which a creation screen for creating a new screen is displayed. In the example shown in fig. 7, a creation screen 101 and a menu bar 102 for creating a new screen are displayed on the display unit 14. The menu bar 102 includes a screen call button 103. When the user desires to place the existing screen data on the creation screen 101 for display to the terminal 3 by screen call, the user clicks the screen call button 103 when the input unit 15 is a mouse. Thus, a screen call is selected.

Next, when the screen call is selected via the input unit 15 (step S2Yes), the call unit 123 displays the screen image list on the display unit 14 and receives the selection of the call screen (step S3). The screen image list is a list of images corresponding to the screen data. The image corresponding to the screen data is, for example, a reduced image of the screen shown in the screen data. Alternatively, the name of the screen data, a list of the identification information, or the like may be displayed as the screen image list. Next, an example of displaying a reduced image of a screen corresponding to screen data as a list of screen images will be described.

Next, the calling unit 123 determines whether or not selection of a calling destination has been instructed (step S4). The selection of the call target refers to processing performed for the purpose of not arranging the entire screen in the screen called by the screen call on the new screen but arranging the object in the called screen on the new screen in units of objects. In the selection of the call target, the user selects an object to be placed on the new screen, that is, an object to be called, via the input unit 15.

If the selection of the call target is not indicated (step S4No), the calling unit 123 arranges the call screen on the creation screen (step S7). In the case where the selection of the call target is not indicated, the called screen as a whole is configured to the creation screen. That is, in this case, the call image is the 1 st screen. Fig. 8 is a diagram showing an example of a screen including a list of screen images and a creation screen on which a call screen is arranged. An example of a screen 200 including a screen image list 201 is shown on the left side of fig. 8, and an example of a creation screen on which a call screen is arranged is shown on the right side of fig. 8. In the example shown in fig. 8, on the screen 200, a screen image list 201 is displayed with a button 202 for "selecting a call destination", an OK button 203, and a cancel button 204. In screen image list 201, image 205 which is a reduced image of screen 1 and image 206 which is a reduced image of screen 2 are displayed. If the user selects image 205 in image list 201 via input unit 15 and clicks OK button 203, the screen data of screen 1 corresponding to image 205 is placed on creating screen 101. The calling screen 207 shows a screen 1 corresponding to the image 205 arranged on the creation screen 101. If the call screen 207 is configured to the creation screen 101, the handle 208 is displayed together with the call screen 207. The user can change the size of the call screen 207 by operating the handle 208 via the input unit 15. Before the adjustment, the call screen 207 is displayed on the creation screen 101 in the same size as the screen displayed on the display 2, for example.

When receiving the resizing of the call screen (step S8Yes), the adjusting unit 124 calculates the ratio based on the resized screen, and sets the calculated ratio to the screen data (step S9). Specifically, for example, when the handle 208 is operated and a confirmation button, not shown, is clicked, the call unit 123 determines that the size adjustment of the call screen is received. When the handle 208 is not operated and a confirmation button, not shown, is clicked, the call unit 123 determines that the size adjustment of the call screen has not been received.

Fig. 9 is a diagram for explaining a calculation method of the scale. A screen 301 created for the display 2 is shown on the left side of fig. 9, and a creation screen 302 being created for display on the terminal 3 is shown on the right side of fig. 9. In the creation screen 302, a screen 301 of fig. 9 is called by a screen call, and is configured as a call screen 303. As shown in fig. 9, the size of the screen 301 is SX1 × SY1, the size of the created screen 302 is DX × DY, and the size of the resized call screen is OX1 × OY 1. In this case, the adjusting unit 124 calculates the ratio X, Y by the following equation (1). Further, SX1, DX, and OX1 show values in the lateral direction, i.e., X-axis direction, and SY1, DY, and OY1 show values in the longitudinal direction, i.e., Y-axis direction. In addition, the scale X shows the scale in the lateral direction, and the scale Y shows the scale in the longitudinal direction.

X＝OX1÷SX1，Y＝OY1÷SY1…(1)

In the present embodiment, a scale is used as the information indicating the size of the call image, and as shown in the above expression (1), the scale is information indicating the ratio of the size of the call image to the size of the 1 st screen.

The adjustment unit 124 calculates the starting point coordinates PX1 and PY1 in the creating screen 302 of the calling screen 303. In the example shown in fig. 9, the coordinates of the start points of the objects within the screen 301, i.e., the switch objects 304, are sox1, soy1, and the coordinates of the start points of the switch objects 305 in the creation screen 302 corresponding to the switch objects 304 are dox1, doy 1. sox1, soy1, and dox1 and doy1 have the relationship shown in the following formula (2). In the following, the coordinate values on each screen are positive in the horizontal direction and positive in the vertical direction, with the direction facing leftward.

dox1＝PX1+sox1×X，

doy1＝PY1+soy1×Y…(2)

When the resize of the call screen is not received (step S8No), the data generation unit 125 determines whether or not an instruction to complete screen creation is received (step S10), and when it is received (step S10Yes), stores screen data corresponding to the created screen in the storage unit 13, and ends the process. At this time, when the data generating unit 125 performs the resizing, the object information corresponding to the call screen is generated using the ratio calculated by the adjusting unit 124 and is added to the screen data. When the screen creation end instruction is not received (step S10No), the drawing support processing unit 121 repeats the processing from step S2.

Fig. 10 is a diagram showing an example of the configuration of screen information in the case where a screen using a screen call is created. In the example shown in fig. 10, screen 1 is a screen created for the display 2, and screen 2 is a screen created for the terminal 3. Screen 1 is configured by screen call in screen 2. Therefore, the object information corresponding to the screen 2 includes information of the call screen 2-1, which is a call screen arranged on the screen 2. Here, as described above, the call screen is also processed as 1 object. The attribute information of the call screen 2-1 includes the above-described ratio X, Y. In the example shown in fig. 10, a screen ID (identifier) and a size are included as attribute information of each screen, and an object ID, a size, and start point coordinates are included as attribute information corresponding to an object. The start point coordinates are coordinates of the top left end of the object in the screen. The object is a square or a rectangle, and for example, in the case of an object drawing a circular shape, the object is also made a square or a rectangle including the circular shape. The picture ID is a number for identifying a picture. When the object is a call screen, the attribute information includes an object ID, a screen ID that is an ID of the call screen, a target object ID, a target area, start point coordinates, and a scale. The object ID is a number for identifying an object. The target object ID and the target area are used when selection of a call target is instructed, which is described later. The object ID and the target area are described later. When the color of the object can be changed, the attribute information of each object may include the color.

When the selection of the call target is instructed in step S4 (step S4Yes), the call unit 123 displays the selection screen of the call target on the display unit 14 (step S5). When selection of a call target is instructed, a call image is specified in units of an area or an object that is an image constituting a call screen. The selection screen of the call target is a screen for receiving selection of an object as the call target. After step S5, the calling unit 123 determines whether or not the call target is selected (step S6), and if the call target is selected (step S6Yes), the call target is placed on the creation screen (step S7). The call target is specified, for example, in units of areas or in units of objects, as will be described later. When the area is designated as a unit, an object included in the area becomes a call target. If the call target is not selected (step S6No), the call unit 123 repeats step S6.

Fig. 11 is a diagram showing an example of a screen including a list of screen images and a selection screen of a call destination. A screen 200 including a screen image list 201 is shown on the left side of fig. 11, an example of a call target selection screen 310 is shown in the center of fig. 11, and a creation screen 101 is shown on the right side of fig. 11. The screen 200 is the same as the example shown in fig. 8. When an image is selected in the screen image list 201 of the screen 200 and then the button 202 which is a button for "selecting a call target" is selected, the call target selection screen 310 is displayed. In the call destination selection screen 310, a call screen corresponding to the image selected in the screen image list 201 is displayed. In the call screen displayed on the call target selection screen 310, an object in the call screen can be selected in units of areas or in units of objects. When the user selects the object unit, the user clicks the "select alone" radio button on the upper portion of the call target selection screen 310, and when the user selects the area unit, the user clicks the "select area" radio button on the upper portion of the call target selection screen 310.

In the example shown in fig. 11, a state is shown in which "select region" is selected and the selection region 311 is selected. The user selects the selection area 311 by, for example, a drag operation. If the selection area 311 is selected, in the creation screen 101, a portion of the calling screen corresponding to the selection area 311 is configured as an area 312. The user can adjust the size of the region 312 by the handle as in the case shown in fig. 8. In addition, when "individually selected" is selected, the selection screen 310 of the call target can select the object unit and the selected object can be arranged on the creation screen 101. The user can adjust the size of the object to be arranged by the handle as in the case shown in fig. 8.

Fig. 12 is a diagram showing an example of object information in a case where a call target is selected in units of areas. In the example shown in fig. 12, in the screen information, the screen 1 is called as a call screen on the screen 2, and a region of a part of the screen 1 is selected as a call target. The object corresponding to the call target is a call screen 2-1 in the example of fig. 12. In the example shown in fig. 12, the object information of the call screen 2-1 stores the start point coordinates and the end point coordinates of the selected area as the target area. The start point coordinates and the end point coordinates are represented by coordinate values on the screen 1. The start point coordinate is the coordinate of the upper left end of the target area, and the end point coordinate is the coordinate of the lower right end. When a call target is selected on a target-by-target basis, an object ID corresponding to the selected object on screen 1 is stored in the target object ID. For example, when the meter 1-1, which is the object constituting the screen 1, is selected as the call target object arranged on the screen 2, 001, which is the object ID of the meter 1-1, is stored in the target object ID in the object information of the call screen 2-1.

Returning to the explanation of fig. 6, after step S7, the calling unit 123 proceeds to step S8, and then step S9 and the subsequent steps are executed. However, as described with reference to fig. 11, when the call target is selected, in step S8, the size of the selected area or the selected object is adjusted, not for the entire call screen. Therefore, in step S9 when the call target is selected, the call unit 123 uses the size of the selected region after the resizing or the size of the selected object after the resizing as OX1 × OY1 when calculating the ratio according to the above expression (1).

If the screen call is not selected in step S2 (step S2No), the call unit 123 proceeds to step S10. In addition, if the resizing of the call screen is not received in step S8 (step S8No), the call unit 123 proceeds to step S10. In this case, X, Y is set to 1.

In the above description, the operation in the case where the screen call is selected has been described, but in addition to the screen call, processing other than the screen call in which a new object or the like is placed on the created screen may be performed. The processing other than the screen call is performed at an arbitrary timing (timing) in the processing shown in fig. 6.

As described above, the drawing support device 1 generates screen data for the terminal 3 and stores the generated screen data in the storage unit 13. The display 2 acquires screen information including screen data for the terminal 3 from the drawing support apparatus 1 and stores the screen information in the storage unit 23. The terminal 3 acquires screen information from the display 2, and performs screen display using screen data for the terminal 3 included in the screen information. The terminal 3 may acquire the image information from the drawing support apparatus 1 without going through the display 2.

Fig. 13 is a flowchart showing an example of the flow of the screen display process in the terminal 3. First, the terminal 3 acquires screen information from the display 2 (step S21). Specifically, the acquisition unit 322 of the terminal 3 transmits a screen information acquisition request to the display 2 via the communication unit 31. Then, the arithmetic unit 22 of the display 2 transmits the screen information stored in the storage unit 23 to the terminal 3 via the communication unit 21. The acquisition unit 322 of the terminal 3 receives the screen information transmitted from the display 2 via the communication unit 31 and stores the screen information in the storage unit 33. Note that, although an example in which the terminal 3 acquires the entire screen information is described here, screen data corresponding to a screen to be displayed and screen data called from the screen data may be acquired instead. In this case, specifically, for example, the terminal 3 checks whether or not the call screen exists in the screen data based on the screen information, and acquires the corresponding screen data when the call screen exists in the screen data.

Next, the display control unit 323 of the terminal 3 acquires object information of the call screen, which is information of the call screen, from the screen data as the display target (step S22). Specifically, the display control unit 323 extracts screen data as a display target from the screen information of the storage unit 33, and acquires object information of the call screen, which is information of the call screen, from the screen data. The object information of the call screen includes an object ID, a screen ID, a target object, a target area, and a scale, as illustrated in fig. 12. Among these pieces of information, information that is not set is stored with a blank or a value indicating that it is not set. For example, when a call is made on a screen-by-screen basis, the target object and the target area are information that is not set.

Next, the display control unit 323 acquires a screen ID from object information of the call screen, which is information of the call screen (step S23). Next, the display control unit 323 determines whether or not the target object ID is set in the object information of the call screen, which is information of the call screen (step S24). When the setting is made (step S24Yes), the display control unit 323 sets the object of the target object ID of the acquired screen ID as the display target (step S25). Specifically, the display control unit 323 searches the acquired screen data of the screen ID from the screen information of the storage unit 33, and searches the object information of the searched screen data for the one including the object ID corresponding to the target object ID. The display control unit 323 sets the object of the object ID obtained by the search as a display target.

Next, the display control unit 323 calculates the size and coordinates of the display target based on the ratio X, Y in the object information of the call screen, which is the information of the call screen (step S26). The size and coordinates of the display target are the size and starting point coordinates of the call screen or call target when the call screen or call target is displayed. Specifically, the display control unit 323 calculates the size and coordinates of the display target using the ratio X, Y in the object information. The calculation method of the size and coordinates for displaying the display target will be described later.

The display control unit 323 displays the display target on the display unit 34 based on the calculated size and coordinates (step S27), and ends the process. Further, when the created screen created for display on the terminal 3 displays a person other than the call screen, the object is displayed based on the screen data.

If the target object ID is not set in step S24 (step S24No), the display controller 323 determines whether or not the target area is set (step S28). When the target area is set (Yes in step S28), the display controller 323 sets the object in the target area of the screen corresponding to the screen ID acquired in step S23 as the display target (step S29), and proceeds to step S26.

If the target area is not set (step S28No), the display controller 323 sets all objects in the screen corresponding to the screen ID acquired in step S23 as display targets (step S30), and proceeds to step S26.

Here, a method of calculating the size and coordinates to be displayed in step S26 will be described. The display control unit 323 determines the size and the start point coordinates of each object to be displayed on the display unit 34 in the following manner. The size of the entire display screen to be displayed on the display unit 34, i.e., the size of the above-described creation screen, is DX and DY. When the display target is the object specified by the object ID, the display control unit 323 acquires the sizes rx1 and ry1 of the object corresponding to the object ID from the object information of the object corresponding to the object ID in the screen data corresponding to the screen ID acquired in step S23. The display control unit 323 extracts the start point coordinates PX1 and PY1 from the object information of the call screen acquired in step S22. The display control unit 323 calculates the dimensions OX1 ', OY 1' for displaying the object and the coordinates PX1 ', PY 1' of the starting points for displaying the object according to the following equations (3) and (4).

PX1′＝PX1，PY1′＝PY1…(3)

OX1′＝rx1×X，OY1′＝ry1×Y…(4)

When the display target is an object within the target area, the display control unit 323 extracts the start point coordinates and the end point coordinates of the target area from the object information of the call screen acquired in step S22. From the extracted start point coordinates and end point coordinates and the object information of the screen data corresponding to the screen ID acquired in step S23, the object information of the object included in the target area in the screen data corresponding to the screen ID is extracted. Then, for each object, the start point coordinates bx1, by1 of the object and the sizes rx1, ry1 of the object are obtained. The display control unit 323 calculates the sizes OX1 'and OY 1' for displaying the objects and the starting point coordinates PX1 'and PY 1' for displaying the objects by the following expressions (5) and (6) for each object to be displayed. PX1 and PY1 are start point coordinates included in the object information of the call screen acquired in step S22.

PX1′＝PX1+bx1×X，

PY1′＝PY1+by1×Y…(5)

OX1′＝rx1×X，OY1′＝ry1×Y…(6)

When the display target is an object in the target area, the display control unit 323 calculates the size OX1 ', OY 1' for displaying the object and the coordinates PX1 'and PY 1' of the starting point for displaying the object by the above equations (5) and (6) based on the object information for all the objects constituting the screen data corresponding to the screen ID acquired in step S23.

The drawing support device 1 according to the present embodiment may automatically perform the resizing when a plurality of screens are arranged by screen call as described below. Fig. 14 is a flowchart showing an example of the flow of the automatic resize process in the case where a plurality of screens are arranged by screen call. The processing shown in fig. 14 is started if an instruction to start creation of a screen to be displayed on the terminal 3 is input via the input unit 15. The creation unit 122 first displays a creation screen for creating a new screen on the display unit 14 (step S41). Next, the calling unit 123 determines whether or not the multi-screen call is selected (step S42). The selection of the multi-screen call is performed by providing a button for selecting the multi-screen call in the menu bar 102 shown in fig. 7 and clicking the button. When the multi-screen call is not selected (step S42No), the calling unit 123 ends the process.

When the multi-screen call is selected (step S42Yes), the calling unit 123 displays the screen image list on the display unit 14 (step S43). Fig. 15 is a diagram showing an example of the screen displayed in step S42. On the left side of fig. 15, a screen 500 including a screen image list 501 is displayed on the display unit 14. On this screen 500, a checkbox 502 for setting whether or not to designate and display the number of divisions, an input field 503 for inputting the number of divisions in the vertical direction, and an input field 504 for inputting the number of divisions in the horizontal direction are displayed. When the user designates and displays the number of divisions, the user can check the check box 502 and input numerical values into the input field 503 and the input field 504. The division number is a value indicating that the created screen is divided into several parts and displayed. For example, when the number of horizontal divisions is designated as 2 and the number of vertical divisions is designated as 2, a total of 4 divided regions in which the creation screen is divided into 2 in the horizontal direction and 2 in the vertical direction are specified. The call screens can be arranged in the divided regions.

When the call screen and the division number, which are screens, are selected (step S44Yes), the call unit 123 determines the ratio and the arrangement corresponding to the division number for the call screen arranged in each of the divided regions (step S45). The configuration is represented by, for example, starting point coordinates. Based on the determined ratio and arrangement, the calling unit 123 arranges the selected calling screen on the creation screen (step S46). On the right side of fig. 15, a state in which a plurality of call screens are displayed in the creation screen 101 is shown.

Here, the number of divided regions is equal to the number of selected screens. When the number of selected screens is larger than the number of divided regions, the calling unit 123 may display an error or may place a part of the number of selected calling screens on the creation screen. When the number of the selected call screens is smaller than the number of the divided regions, the call unit 123 does not place a call screen in a part of the divided regions.

In step S45, the calling unit 123 determines the ratio X, Y and the start point coordinates for each calling screen, for example, as follows. The created screen has a size DX × DY, the number of horizontal divisions KX, the number of vertical divisions KY, and the original sizes of the call screens created for the display 2 are SX1 and SY 1. At this time, the ratio X, Y is calculated by the following equation (7).

X＝(DX÷KX)÷SX1，Y＝(DY÷KY)÷SY1…(7)

Starting point coordinates PX arranged in the ith (i is an integer of 1 or more) from the left and the jth (j is an integer of 1 or more) from the top of the call screen_i，j、PY_i，jThe calculation is performed by the following equation (8).

PX_i，j＝(i－1)×(DX÷KX)，

PY_i，j＝(j－1)×(DY÷KY)…(8)

As to which calling screen is arranged in which area, an arbitrary rule determined in advance may be used, or the user may select it.

Returning to the explanation of fig. 14, after step S46, it is determined whether or not an instruction to complete screen creation is received (step S47) in the same manner as step S10 of fig. 6, and if so (step S47Yes), screen data corresponding to the created screen is stored in the storage unit 13, and the processing is terminated. At this time, the data generation unit 125 generates object information corresponding to the call screen using the calculated ratio and the start point coordinates, and adds the object information to the screen data. If the screen creation end instruction has not been received (step S47No), the drawing assistance processing unit 121 repeats the processing from step S42. In general, the calling process is the process of step S2 and thereafter in fig. 6.

As described above, the screen information including the screen data corresponding to the creation screen on which the plurality of call screens are arranged is received by the terminal 3 via the display 2, similarly to the screen information including the screen data created by the processing of fig. 6. The terminal 3 can display a screen on which a plurality of call screens are arranged by the processing shown in fig. 13 using the screen information. That is, in this case, the calling image is a plurality of 1 st screens, the calling unit 123 receives an input of the number of divisions for dividing the new screen, calculates the arrangement positions and sizes of the plurality of 1 st screens for arranging the plurality of 1 st screens on the new screen based on the number of divisions, and arranges the plurality of 1 st screens on the 2 nd screen based on the calculated arrangement positions and sizes.

The drawing support device 1 of the present embodiment may also set the editing permission/non-editing permission information for each screen. The creation unit 122 receives, from the user via the input unit 15, for each screen, a setting of whether or not to edit the screen when the screen is called as a calling screen. That is, when the 1 st screen is used as the call image, the creation unit 122 receives input of information indicating whether the call image can be edited or not. Fig. 16 is a diagram showing an example of a setting screen for editing permission. The setting screen 401 shown in fig. 16 is displayed on the display unit 14 at the time of screen creation, for example. The setting screen 401 includes: a checkbox 402 for setting whether or not size change is permitted; and a checkbox 403 for setting whether or not color change is permitted. The setting screen 401 further includes: a checkbox 404 for setting whether or not to allow a change of the position; a checkbox 405 for setting whether or not addition of an object is permitted; and a checkbox 406 for setting whether deletion of the object is permitted. The creation unit 122 receives settings for the possibility of various kinds of editing, for example, via a setting screen 401 shown in fig. 16.

Fig. 17 is a diagram showing an example of screen data in the case of setting whether to allow editing. As shown in fig. 17, the screen data includes information indicating whether editing is possible or not, for each editing item for which editing is possible or not. That is, the 1 st screen data includes information indicating whether editing is possible or not. The information indicating whether the editing is editable or non-editable is set to 1 in the case of being editable, and set to 0 in the case of being non-editable, for example. Fig. 17 shows an example in which the color of each object can be changed, and the attribute information includes a color. Fig. 18 is a diagram showing an example of a creation screen in a case where a screen whose size is set to be unchangeable is called as a call screen. In the example shown in fig. 18, a handle for changing the size is not displayed on the call screen 600. When a screen set to be changeable in size is called, a handle is displayed to allow the size to be changed.

As described above, in the present embodiment, when creating a new screen for display on a device different from the device on which the existing screen is displayed, using the existing screen, a change in the size of the existing screen placed on the new screen is received. This makes it possible to easily change the size of the existing screen data when creating the display screen by using the existing screen data. In the present embodiment, the objects arranged on the new screen can be selected in units of areas or in units of objects in the existing screen. This allows a new screen to be created flexibly according to the size, application, and the like of the device to be displayed.

The configuration shown in the above embodiment is an example of the contents of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or modified without departing from the scope of the present invention.
