Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a control system 1a according to the first embodiment.
As shown in this figure, the control system 1a includes a device control module 10, a display control device 20, a display panel 220, and a touch panel 230. Among these, the device control module 10 includes a device control unit 100 such as a microcomputer, a RAM (Random Access Memory) 102, a ROM (Read Only Memory) 104, and a target device 110 to be controlled. . Here, the target device 110 is, for example, a compressor motor if it is assumed to be applied to an air conditioner. In this case, the device control unit 100 is configured to execute a device control program stored in the ROM 104 to control on / off of the motor, the number of rotations (air flow rate), and the like.

  On the other hand, the display panel 220 is a flat display such as a liquid crystal display device or an organic EL (Electro Luminescence) device. On the other hand, the touch panel 230 detects a touch position (XY coordinate value) on the screen displayed by the display panel 220 and outputs position information indicating the detected touch position.

The display control device 20 performs a display instruction for the display panel 220 or a control instruction for the device control module 10 based on the position information output from the touch panel 230. The UI control unit 200, the RAM 202, ROMs 204 and 214 and a drawing unit 210 are included.
The UI control unit 200 is a microcomputer that executes a control program stored in the ROM 204 while using the RAM 202 as a temporary storage area, and displays display components such as operated buttons and numeric dials from position information from the touch panel 230. And instructing the drawing unit 210 what to draw (including animation) according to the drawing sequence program described later stored in the ROM 204, interpreting the script corresponding to the specified display component, Control information such as instructions and numerical information, which are descriptive information, is transmitted to the device control unit 100.
The ROM 214 stores image information to be described later. The drawing unit 210 reads out image information designated by the UI control unit 200 from the ROM 214 and causes the display panel 220 to draw an image.

  In this way, on the display panel 220, the contents according to the drawing sequence program are displayed. On the other hand, when an operation such as a touch operation is performed on the touch panel 230, control information corresponding to the operation is displayed on the UI control unit 200. Is output from. In the device control module 10, the device control unit 100 controls the target device 110 according to the control information by executing a device control program.

FIG. 2 is a diagram illustrating a software hierarchy in the control system 1a.
As shown in this figure, in the device control module 10, the device control program 12 is located on the hardware driver 162. The hardware driver 162 includes firmware on the device control module 10 side, an operating system, a device driver for controlling the target device 110, and the like.
On the other hand, in the display control device 20, the UI interpretation unit 264 and the drawing sequence program 64 are sequentially positioned on the hardware driver 262. The hardware driver 262 includes firmware on the display control device 20 side, an operating system, a device driver for the display panel 220, and the like. The UI interpretation unit 264 interprets a display component on which an operation such as touch is performed.
The drawing sequence program 64 arranges display parts such as buttons, number dials, and pictograms in what layout, and in what size and how they are changed (transitioned) with respect to the display area of the display panel 220. And the like, and the display contents are associated with control information to the device control unit 100 such as numerical information and instructions.

FIG. 3 is a diagram showing creation of a drawing sequence program. In this figure, the production tool 32 and the conversion tool 34 are each installed in a personal computer and are executed as application programs.
The operator arranges display parts such as buttons, numbers, and pictograms in the production tool 32 in any size and in any layout by quoting or processing the image material 40 prepared in advance. The content 50 to be displayed on the display panel 220 is created by defining how the transition is made. At this time, the display component also defines a command and numerical information to be output corresponding to the operation when the display component is operated. The content 50 created in this manner draws image information 52 that is a set of a plurality of pieces of image information (including animation) indicating various display components and the like, displays display contents, and outputs commands, numerical information, and the like. The drawing sequence program 54 is included. Note that the display content including animation is determined by the interaction between the content included in the image information 52 and the content related to the display defined by the drawing sequence program 54. It can be arbitrarily determined.

The content 50 can be played back if the condition is satisfied in the personal computer, but high computing power is required for the playback. In the present embodiment, the target for display control of the content 50 is the display control device 20, and its computing capability is inferior to that of a personal computer.
For this reason, in order to cause the display control device 20 to perform display control of the contents defined by the content 50, the operator converts the drawing data 60 into a dedicated format by the conversion tool 34. The converted drawing data 60 includes image information 62 and a drawing sequence program 64. The image information 62 is the image information 52 and the drawing sequence program 64 is a drawing sequence program 54 specialized for execution on the display control device 20.
The drawing data 60 is transferred to and stored in the ROM of the display control device 20 in FIG. 1 by connecting the display control device 20 to a personal computer and performing a predetermined operation. Specifically, the drawing sequence program 64 is stored in the ROM 204 and the image information 62 is stored in the ROM 214.

  FIG. 4 is an example of a display screen on the display panel 220, and is an example in which the drawing unit 210 is made to draw on the display panel 220 in accordance with the drawing sequence program 64 read from the ROM 204 by the UI control unit 200. This figure is a display example when an air conditioner is assumed as the target device 110, and a display area 222 for setting a set (target) temperature with three significant digits starting from the first decimal place and an operation mode are set. Software buttons 225-227. In this example, the three-digit number wheel in the display area 222 is associated with information indicating that the number represented by the three digits is the set (target) temperature in addition to the respective numeric information. In addition, each of the software buttons 225 to 227 is associated with an instruction for setting the operation mode to cooling, drying, or blowing.

For example, when the operator touches the touch panel 230, the UI control unit 200 acquires the touched position information from the touch panel 230, and corresponds to which display component the position information corresponds to the drawing content by the drawing unit 210. Determine whether you are doing.
When the touch is on a part that does not correspond to the display component, the UI control unit 200 determines that the operation is invalid and does not output a command or information to the drawing unit 210 or the device control unit 100. . Therefore, the invalid operation is not reflected on the display content by the drawing unit 210 or the control of the target device 110 by the device control unit 100.

On the other hand, when the touch is on the part corresponding to the display component, the UI control unit 200 selects image information to be drawn according to the operation content on the touch panel 230, and issues an instruction to draw the selected image information. While being supplied to the drawing unit 210, a command or numerical information associated with the touched display component is supplied to the device control unit 100.
For example, in the case of a touch operation on the software button 225, the UI control unit 200 uses the operation information indicating that the software button 225 has been touched according to the drawing sequence program 64 stored in the ROM 204. The drawing unit 210 is instructed to draw image information corresponding to the touch operation. Then, the drawing unit 210 reads the instructed image information from the ROM 214 and causes the display panel 220 to display it. As a result, as shown in FIG. 5, the display contents of the display panel are moved to the back side of the drawing and the display color is changed so that the software button 225 is actually pressed. Is done.
Further, the UI control unit 200 generates a command associated with the software button 225 according to the drawing sequence program 64, here, a command for cooling the operation mode, and outputs the generated command to the device control unit 100. As a result, the device control unit 100 changes the control content to the cooling mode in the control operation of the target device 110 according to the device control program 12.

  Further, for example, in the case of a touch operation on the display area 222, the UI control unit 200 determines operation information indicating which digit is operated in which direction and at which speed, and the operation is performed according to the drawing sequence program 64. The drawing unit 210 is instructed to draw an image corresponding to. Then, the drawing unit 210 draws the display content corresponding to the touch operation according to the content instructed from the UI control unit 200. As a result, as shown in FIG. 6A, the display content of the display panel is displayed so that the touched numeric digit actually moves with the touch operation. When the set temperature is changed in the display area 222 as shown in FIG. 6B in this way, the UI control unit 200 simultaneously generates numerical information corresponding to the touch operation according to the drawing sequence program 64, The numeric information is output to the device control unit 100. As a result, the device control unit 100 changes the control content so as to achieve the newly set target temperature in the control operation of the target device 110 according to the device control program 12.

In the present embodiment, display control according to the drawing sequence program 64 on the display control device 20 side and control of the target device 110 by the device control program 12 in the device control module 10 are independent of each other. Therefore, according to the present embodiment, the contents of display control can be easily changed by updating the drawing sequence program 64 without affecting the contents of control on the target device 110.
In the present embodiment, the drawing sequence program 64 is obtained by converting the content 50 (drawing sequence program 54) produced by the production tool 32 of the personal computer with the conversion tool 34. In a personal computer or the like having a reproduction environment, the content 50 before conversion can be reproduced. Therefore, in the personal computer, the content of display control executed by the display control device 20, that is, the operation content of the drawing sequence program 64 is displayed. Can be confirmed.

  Next, a control system 1b according to the second embodiment of the present invention will be described. In the control system 1a according to the first embodiment, the instruction to the device control module 10 is given by the display control device 20, but in the control system 1b according to the second embodiment, the terminal device 80 in addition to the display control device 20 is also used. It is something that can be done.

FIG. 7 is a block diagram showing a schematic configuration of the control system 1b. In the control system 1b in this figure, a terminal device 80 and an interface (I / F) 106 are provided with respect to the control system 1a shown in FIG.
The terminal device 80 is a multi-function mobile phone, a tablet computer, or the like, and has communication functions such as infrared communication and short-range wireless communication. The terminal device 80 also includes a display panel 240 and a touch panel 250 superimposed on the display panel. Note that the specifications (display size and resolution) of the display panel 240 in the terminal device 80 may be different or the same as the specifications of the display panel 220 in the display control device 20. The I / F 106 transmits information transmitted from the device control unit 100 to the terminal device 80, while receiving information transmitted from the terminal device 80 and transfers the information to the device control unit 100.

FIG. 8 is a diagram illustrating a software hierarchy in the control system 1b.
As shown in this figure, in the terminal device 80, an emulator 90, a UI interpretation unit 264, and a drawing sequence program 64 are positioned in the hardware driver 862 in order. Among them, the drawing sequence program 64 is obtained by converting the content 50 (drawing sequence program 54) in FIG. 3 with the conversion tool 34 and installing it in the terminal device 80.
The hardware driver 862 includes firmware in the terminal device 80, an operating system (OS), a device driver for the display panel 240, and the like.
Further, the emulator 90 and the drawing sequence program 64 may be installed in the terminal device 80 by downloading from a specific server.

Since the terminal device 80 operates its own OS, and the drawing sequence program 64 assumes the operation of the display control device 20, the drawing sequence program 64 cannot operate correctly on the terminal device 80 as it is. Therefore, software that imitates the execution environment of the display control device 20 in the terminal device 80 is an emulator 90 (emulation program). The emulator 90 displays the content 50 on the display panel 240 of the terminal device 80, and outputs a command or numerical information according to a touch operation. The device control unit 100 receives numeric information, commands, and the like output from the terminal device 80 and inputs them via the I / F 106. Then, the device control unit 100 controls the target device 110 based on the input numeric information and commands.
In the second embodiment, as a matter of course, the instruction to the device control module 10 may be performed not by the terminal device 80 but by the display control device 20.

  In the second embodiment, the target device 110 is controlled by a terminal device 80 other than the display control device 20. For this reason, the operator can control remotely at a point away from the target device 110.

Note that in the second embodiment, the content contents when displayed on the display control device 20 and the terminal device 80 are the same. However, for example, the button shape, the size and arrangement of display components, and the like are matched to the specifications of the display panel 240. It may be changed.
Further, when the content 50 produced by the production tool 32 has a versatile format and the terminal device 80 is equipped with a program of the format, the terminal device 80 can be used without the emulator 90. 50 (drawing sequence program 64) can be reproduced (executed).
