Description

 The present invention relates to a display operation device that performs processing according to the pressed coordinates of a pressing operation by performing a click operation or a drag operation on a touch panel using an input unit such as a finger or a pen.

  Conventionally, as this type of display operation device, there is a display operation device having a function as an operation terminal for controlling electrical equipment such as equipment and home appliances. For example, in the field of air conditioning management systems, a display operation device as a centralized controller for air conditioning equipment in a building is provided with a touch panel integrated with the screen in consideration of the convenience of the user, and the user performs a press operation on the touch panel. In addition, individual device control and collective control are possible.

  In recent years, in the field of home networks, which have been widely spread, touch panels have been used as home controllers that collectively manage household electrical appliances (IH cooking heaters, air conditioners, lighting, etc.) in the home.

  An example of a display operation device using a conventional touch panel will be described. The display operation device is based on a touch panel controller that detects a press operation on the touch panel by an input unit such as a finger or a pen, a display integrated with the touch panel, and a press coordinate detected by the touch panel controller. And a CPU that performs (pressed coordinate processing).

  The touch panel controller outputs an interrupt signal to the CPU upon detection of the pressing operation. Upon detecting the interrupt signal, the CPU stops the main process and starts the interrupt process, acquires the pressed coordinates from the touch panel controller, and stores the pressed coordinates in the buffer (coordinate acquisition process). Then, the CPU performs processing (pressed coordinate processing) corresponding to the pressed coordinate stored in the buffer. In the pressed coordinate processing, it is confirmed that the pressed coordinates are stored in the buffer, and control information communication processing to the electric device (controlled device) and drawing update processing to the display are performed.

  In the conventional display operation device, since the processing is performed as described above, even when the processing load of the CPU is high due to processing other than the interrupt processing, the interrupt processing is preferentially executed. As a result, other processes may be affected.

  Therefore, there is a technique that makes it possible to reduce the influence on other processes by performing an interrupt process with a processing capacity corresponding to the current load of the CPU (see, for example, Patent Document 1). In Patent Document 1, the processing interval of the pressed coordinate processing that changes according to the current processing load of the CPU is detected on the touch panel controller side, and the interval at which an interrupt signal is output from the touch panel controller to the CPU according to the processing interval, that is, The interval at which the CPU performs the pressed coordinate processing is dynamically changed.

JP 2003-84907 A (4th page)

  In the technique of Patent Document 1, the touch panel controller side determines the processing interval of the pressed coordinate processing, in other words, the time interval for acquiring the pressed coordinate in accordance with the processing load of the CPU. For this reason, when the CPU load is high due to other processes, for example, when a character input is performed by dragging the touch panel with a pen or a finger, the acquisition interval of the pressed coordinates becomes long, and character recognition is performed. There is a possibility that the pressed coordinates with sufficient accuracy cannot be obtained. Therefore, when it is necessary to detect the locus of the pressed coordinates in a drag operation such as character input, it is desirable that the pressed coordinates can be acquired at short intervals in preference to other processing.

  On the other hand, when the user presses an icon on the touch panel, a pressed coordinate process corresponding to the icon arranged at the pressed coordinate is executed as the operation of the CPU. Therefore, it is sufficient if the first pressed coordinates can be acquired, and then the pressed coordinate acquisition process when the user continues to press the same position on the touch panel is unnecessary. For this reason, it is only necessary to acquire the coordinate acquisition process only at the start of pressing, and thereafter, the CPU performance can be effectively used by assigning the CPU capability to other processes.

  The present invention has been made in view of the above points, and allows the CPU that controls the entire display operation device to set the acquisition processing interval for acquiring the pressed coordinates, with priority given to the acquisition number of the pressed coordinates, or the CPU. An object of the present invention is to provide a display operation device capable of flexibly selecting whether to reduce the processing load.

A display operation device according to the present invention is a display operation device that performs processing according to the pressed coordinates of a pressing operation on a touch panel, and includes a display unit that displays a screen, a touch panel formed on the screen of the display unit, Press detection means for detecting coordinates pressed on the touch panel, and processing means for performing processing according to the press coordinates detected by the press detection means and controlling the entire apparatus , and switching a user input method to the touch panel according to the press coordinates And an interrupt control means for outputting an interrupt signal to the processing means, and the processing means determines the interrupt interval based on the input method corresponding to the pressed coordinates detected by the press detection means, and performs interrupt control. Having an interrupt interval determining means for notifying the means, and upon receiving an interrupt signal output at an interrupt interval from the interrupt control means in response to the notification, obtains the pressed coordinates from the press detecting means. It is intended.

According to the present invention, the processing means for controlling the entire apparatus determines the interrupt interval for acquiring the pressed coordinates from the pressed detection means based on the input method corresponding to the pressed coordinates detected by the pressed detection means. It is possible to flexibly select whether to give priority to the number of acquired pressed coordinates or to reduce CPU processing load according to the pressing operation on the touch panel.

  The present invention is a display operation device that has a touch panel and performs processing according to the pressed coordinates by a pressing operation on the touch panel. Here, in particular, electric appliances such as home appliances and equipment in a home network. A display operation device that is connected to these electric devices and functions also as an operation terminal for controlling them in the system to be configured will be described. The present invention enables the CPU that controls the entire display operation device to set the acquisition processing interval for acquiring the pressed coordinates from the touch panel controller connected to the touch panel, not by the touch panel controller but by the CPU, and can be pressed at short intervals. In the case where it is necessary to acquire coordinates, one feature is that the acquisition processing of the pressed coordinates is performed by the CPU in preference to other processing. In the following first to third embodiments, various configurations for controlling the number of times pressed coordinates are acquired under CPU initiative will be described in order.

Embodiment 1 FIG.
The display operation device according to the first embodiment draws a power supply icon, a strength switching icon, and the like on the display screen, and selects and presses these icons to change the input method when the user inputs data on the touch panel, depending on the icon. Run the application. Here, there are two types of input methods, for example, a “selection input mode” in which icons are simply selected / deselected and a “pen input mode” in which characters can be input by an input means such as a pen. The display operation device according to the first embodiment dynamically changes the acquisition interval of the pressed coordinates of the touch panel according to the input method.

FIG. 1 is a block diagram of the display operation device according to the first embodiment.
The display operation device in FIG. 1 includes a touch panel 1, a touch detection controller 21 including a press detection unit 21, an interrupt interval setting unit 22, an interrupt control unit 23, and a coordinate transmission unit 24, an interrupt interval determination unit 31, and coordinate reception. A CPU 3 as a processing means including a means 32, a central processing means 33, an interrupt receiving means 34 and an input method storage means 40, a display means 4, and a communication means 5 are provided.

  The touch panel 1 is an interface that accepts a pressing operation by an input means such as a user's finger and pen, and is formed on the screen of the display means 4.

Hereinafter, the configuration of the touch panel controller 2 will be described first.
The press detection unit 21 detects that the touch panel 1 is pressed, outputs the pressed state to the interrupt control unit 23, and sets the pressed coordinates in accordance with a request from the coordinate transmission unit 24. It outputs to the coordinate transmission means 24 by a time interval (interrupt interval mentioned later).

  The interrupt control means 23 outputs an interrupt signal to the interrupt reception means 34 that the CPU 3 has. The output timing of the interrupt signal to the interrupt receiving means 34 is determined by the interrupt interval determining means 31 on the CPU 3 side and is based on the interrupt interval set in the interrupt interval setting means 22. Further, the interrupt control means 23 stops outputting the interrupt signal when receiving an instruction to stop the interrupt signal output from the coordinate transmitting means 24 after the output of the interrupt signal is started.

  The interrupt interval setting unit 22 sets the interrupt interval determined by the interrupt interval determination unit 31 included in the CPU 3.

  The coordinate transmission unit 24 outputs the pressed coordinates detected by the pressing detection unit 21 to the coordinate receiving unit 32 of the CPU 3 in response to the pressed coordinate acquisition request from the coordinate receiving unit 32 of the CPU 3. Further, after the output of the pressed coordinates is completed, the interrupt control means 23 is instructed to stop outputting the interrupt signal.

Next, the configuration of the CPU 3 will be described.
The central processing means 33 performs software processing in the display operation device. Software processing is classified into main processing that is normally executed and interrupt processing that is executed when an interrupt occurs. In the main process, based on the pressed coordinates received by the coordinate receiving means 32, the display contents updating process displayed by the display means 4, the input method switching process of the display operation device, and the transfer of control information to and from the electrical equipment are communicated. 5 performs communication processing performed through 5. The interrupt process is a process that starts when an interrupt signal is received from the touch panel controller 2 via the interrupt acceptance means 34, and the pressed coordinates are obtained from the coordinate transmission means 24 of the touch panel controller 2 via the coordinate reception means 32. Coordinate acquisition processing is performed.

  When the interrupt receiving means 34 detects an interrupt signal during execution of the main process, the central processing means 33 interrupts the main process and starts the interrupt process. Then, after the interruption process is completed, the interrupted main process is resumed. Further, when receiving the pressed coordinates, the central processing means 33 determines an input method based on the icon arranged at the pressed coordinates, and stores the determined input method in the input method storage means 40.

  The interrupt receiving unit 34 detects an interrupt signal output from the interrupt control unit 23 included in the touch panel controller 2 and notifies the central processing unit 33 of the detection.

  In response to a request from the central processing means 33, the coordinate receiving means 32 transmits a pressed coordinate acquisition request to the coordinate transmitting means 24 on the touch panel controller 2 side and receives the pressed coordinates.

  The input method storage means 40 stores the currently set input method. As described above, the input method includes the “pen input mode” and the “selection input mode”. The input method is set in advance for each icon on the screen displayed on the display unit 4, and the setting contents are as follows. It is stored in the central processing means 33.

  The interrupt interval determination means 31 stores therein an interrupt interval preset for each input method, determines an interrupt interval corresponding to the input method stored and set in the input method storage means 40, The determined interrupt interval is output to the interrupt interval setting means 22.

  The interrupt interval determination means 31 monitors the change of the input method of the input method storage means 40, and when the input method is changed, the touch panel controller 2 has an interrupt interval defined in advance for each input method. To the interval setting means 22.

  The display means 4 is a display that displays images and characters.

  The communication unit 5 is connected to an electrical device via a network, and exchanges control information with the electrical device in response to a request from the central processing unit 33.

  Next, the operation of the touch panel controller 2 in the display operation device according to the first embodiment will be described.

FIG. 2 is a flowchart showing the operation of the touch panel controller 2 in the display operation device of the first embodiment.
After the power is turned on, the touch panel controller 2 checks whether or not the touch detection unit 21 detects a press on the touch panel 1 with the interrupt control unit 23 (S1), and waits until a press is detected. In other words, the press detection unit 21 detects a pressing state (starting pressing, during pressing) on the touch panel 1, and outputs the detection result to the interrupt control unit 23. The interrupt control unit 23 includes the press detection unit 23. It is checked whether or not a press on the touch panel 1 is detected according to the result from 21.

  The interrupt control means 23 checks whether or not it is the timing to output an interrupt signal based on the interrupt interval set by the interrupt interval setting means 22 when the press detection means 21 detects a press on the touch panel 1. To do. That is, it is checked whether the elapsed time from the start of the previous interrupt signal output is equal to or greater than the interrupt interval (S2), and if it is equal to or greater than the interrupt interval, the interrupt signal output is started (S3). If the elapsed time is less than the interrupt interval, no interrupt signal is output and the process returns to step S1.

  Then, the coordinate transmission unit 24 continues to wait for the pressed coordinate acquisition request output from the coordinate receiving unit 32 of the CPU 3 by outputting the interrupt signal from the interrupt control unit 23 to the CPU 3, and receives the pressed coordinate acquisition request. Then, it requests and receives the pressed coordinates from the pressing detection means 21 and outputs it to the coordinate receiving means 32 on the CPU 3 side (S5). After completing the output of the pressed coordinates, the coordinate transmission unit 24 instructs the interrupt control unit 23 to stop outputting the interrupt signal. Receiving the instruction, the interrupt control means 23 stops the interrupt signal (S6) and returns to step S1.

Next, the operation of the CPU 3 in the display operation device according to the first embodiment will be described.
FIG. 3 is a flowchart illustrating the operation of the CPU 3 in the display operation device according to the first embodiment.

  After the power is turned on, the CPU 3 performs an initialization process such as displaying an initial screen on the display unit 4, initializing the communication unit 5, and initializing the input method to "selection input mode" (S11), and then performing a main process. Is activated (S12).

  The central processing unit 33 executes main processing, and repeatedly performs communication processing with control information with the electrical equipment, update processing of display contents on the display unit 4 based on the control information, and the like. In the main process, it is monitored that the pressed coordinates from the touch panel controller 2 are stored in the buffer 33a. If the pressed coordinates are not stored in the buffer 33a (S13), the main process is continued. (S14) When the pressed coordinates are stored in the buffer 33a, the pressed coordinates processing is performed (S15).

  By the way, when the touch panel controller 2 detects that the touch panel 1 is pressed, the touch panel controller 2 starts outputting an interrupt signal to the CPU 3 (step S3 in FIG. 2). When the start of output is detected, interrupt processing is performed.

FIG. 4 is a flowchart showing the flow of interrupt processing.
When the interrupt receiving means 34 of the CPU 3 detects the start of the output of the interrupt signal output from the interrupt control means 23 of the touch panel controller 2 (S21), it notifies the central processing means 33 of the detection, and the central processing means 33 In 33, the main process being executed in step S12 is interrupted (S22), and the coordinate acquisition process is started (S23).

FIG. 5 is a flowchart showing the flow of the coordinate acquisition process of FIG.
In the coordinate acquisition process, the central processing unit 33 requests the touched coordinate from the touch panel controller 2 via the coordinate receiving unit 32 (S23a), and receives the pressed coordinate transmitted from the touch panel controller 2 in response to the request (S23a). S23b). Then, the pressed coordinates are stored in the internal buffer 33a (S23c), and the coordinate acquisition process is terminated.

  When the coordinate calculation process is completed, the central processing means 33 resumes the main process from the interrupted process shown in FIG. 4, that is, the point where the process was interrupted before the coordinate acquisition process (S24).

  The CPU 3 performs the pressed coordinate processing (step S15 in FIG. 3) when the pressed coordinates are stored in the buffer 33a as described above. The pressed coordinate processing will be described below.

FIG. 6 is a flowchart showing the flow of the pressed coordinate processing of FIG.
The central processing means 33 performs a process corresponding to the icon arranged at the pressed coordinate stored in the buffer 33a (S15a). That is, for example, an input method switching process and a display content updating process on the display unit 4 are performed. Then, the central processing means 33 checks the input method corresponding to the icon arranged at the pressed coordinates stored in the buffer 33a (S15b), and the icon arranged at the pressed coordinates starts the input of the electric device name. If the requested icon, the content of the input method storage means 40 is rewritten to “pen input mode”, and a character input acceptance screen (pen input screen) as shown in FIG. 7 is displayed on the display means 4 (S15c). The interrupt interval determining unit 31 detects that the input method has been changed, and outputs and sets the interrupt interval (50 ms) in the “pen input mode” to the interrupt interval setting unit 22 of the touch panel controller 2. (S15d).

  On the other hand, if the result of step S15b is “selection input mode”, specifically, for example, if the icon arranged at the pressed coordinate is a pen input confirmation icon, the content of the input method storage means 40 is changed to “selection input mode”. " The interrupt interval determination unit 31 detects that the input method storage unit 40 has been updated, and outputs the interrupt interval (500 ms) in the “selection input mode” to the interrupt interval setting unit 22 included in the touch panel controller 2. (S15e). Note that if the pen input confirmation icon is pressed during the current pressed coordinate processing after the icon that requests the start of input of the electrical device name is pressed during the previous pressed coordinate processing, the contents of the input method storage unit 40 Is set to the “selection input mode”, and control is performed to return the screen of the display means 4 from the character input acceptance screen to the screen displayed before the display of the character input acceptance screen.

  According to the first embodiment, the input method is set according to the pressed coordinates when the touch panel 1 is pressed, and the CPU 3 determines the interrupt interval according to the input method. The insertion interval can be determined, and it is possible to flexibly select whether the priority is to obtain the number of pressed coordinates or to reduce the CPU processing load according to the pressing operation on the touch panel. Specifically, when the input method is “selection input mode”, by setting the interrupt interval to a long interval, the output interval of the interrupt signal of the touch panel controller 2 becomes longer, and the CPU 3 interrupts the main process. The number of times the interrupt process is activated can be suppressed. Therefore, the CPU processing load can be suppressed, and the influence of the interrupt process on other processes can be avoided. In other words, it is only necessary to know the pressed coordinates at the start of pressing, and for icons that do not require the pressed coordinates that are notified while continuing to press, the number of times that interrupt processing is started by increasing the interrupt interval is suppressed. This suppresses the CPU processing load.

  In addition, when the input method is “pen input mode” and it is necessary to acquire the pressed coordinates at a short interval for accurate character recognition, by setting the interrupt interval short, the touch panel controller 2 The output interval of the interrupt signal is shortened, and the pressed coordinates can be acquired at short intervals. At this time, the CPU processing load increases, which may affect other processes, but it is possible to perform character recognition accurately.

Embodiment 2. FIG.
The display operation device according to the second embodiment is configured so that the CPU 3 acquires the pressed coordinate from the touch panel controller 2 in accordance with the operation attribute (clickable and draggable) of the icon arranged at the pressed coordinate (number of times). And acquisition interval) are dynamically changed.

FIG. 8 is a block diagram of the display operation device according to the second embodiment.
The display operation device in FIG. 8 includes a touch panel 1, a press detection unit 21, an interrupt mode setting unit 25, an interrupt control unit 23, a coordinate transmission unit 24, an interrupt mode setting unit 25, and an operation state detection unit 26. CPU 3 including controller 2, interrupt mode determining means 35, coordinate receiving means 32, central processing means 33, interrupt receiving means 34, icon management means 36 and display control means 37, display means 4, communication means 5 It has.

  The touch panel 1 is an interface that accepts a pressing operation by an input means such as a user's finger and pen, and is formed on the screen of the display means 4.

Hereinafter, the configuration of the touch panel controller 2 will be described first.
The press detection unit 21 detects that the touch panel 1 is pressed, outputs the pressed state to the operation state detection unit 26, and coordinates the pressed coordinates in response to a request from the coordinate transmission unit 24. Output to the transmission means 24.

  The operation state detection unit 26 detects the operation state of the user with respect to the touch panel 1 based on the detection result of the press detection unit 21. The operation states include “release”, “pressing start”, and “pressing”, and each represents a state where the touch panel 1 is not pressed, a state where pressing is started, and a state where pressing continues without being released. .

  The interrupt control means 23 outputs an interrupt signal to the interrupt reception means 34 that the CPU 3 has. The output timing of the interrupt signal to the interrupt receiving means 34 is determined by the interrupt mode determining means 35 on the CPU 3 side, and an interrupt mode described later set in the interrupt mode setting means 25 and the operation state detecting means 26. Is based on an output condition (interrupt interval) corresponding to the combination with the detected operation state, and is preset in the interrupt control means 23 as an interrupt interval. Further, the interrupt control means 23 stops outputting the interrupt signal when receiving an instruction to stop the interrupt signal output from the coordinate transmitting means 24 after the output of the interrupt signal is started.

  The interrupt mode setting unit 25 sets the interrupt mode determined by the interrupt mode determination unit 35 included in the CPU 3. Here, the interrupt mode includes a “simple mode” and a “detail mode”, which are set in advance for each operation attribute to be described later of the icon displayed on the screen, and when the touch panel 1 is pressed. It is determined by the interrupt mode determining means 35 of the CPU 3 according to the operation attribute of the icon arranged at the pressed coordinate. Specifically, in the interrupt mode, for example, an icon that cannot be dragged such as a background image or a determination button is set to “simple mode”, and an icon that can be dragged is set to “detailed mode”.

  The coordinate transmission unit 24 outputs the operation state detected by the operation state detection unit 26 and the pressed coordinate detected by the press detection unit 21 to the coordinate reception unit 32 in response to a request from the coordinate reception unit 32 of the CPU 3. . In addition, after completion of the output of the operation state and the pressed coordinates, the interrupt control means 23 is instructed to stop outputting the interrupt signal.

Next, the configuration of the CPU 3 will be described.
The central processing means 33 performs software processing in the display operation device. Software processing is classified into main processing that is normally executed and interrupt processing that is executed when an interrupt occurs. In the main processing, based on the operation state and the pressed coordinates received by the coordinate receiving means 32, the display contents displayed on the display means 4 are updated via the display control means 37, and the pressed coordinate interrupt mode determining means 35 is updated. Notification processing, update operation of the icon managed by the icon management means 36 and display coordinates where the icon is arranged, communication processing for transmitting / receiving control information to / from the electric device through the communication means 5 and the like. The interrupt process is a process that is started when an interrupt signal is received from the touch panel controller 2 via the interrupt accepting unit 34. A process for acquiring the pressed coordinates is performed.

  Further, when the interrupt receiving means 34 detects an interrupt signal during execution of the main process, the central processing means 33 interrupts the main process and starts the interrupt process. Then, after the interruption process is completed, the interrupted main process is resumed.

  The interrupt receiving unit 34 detects an interrupt signal output from the interrupt control unit 23 included in the touch panel controller 2 and notifies the central processing unit 33 of the detection.

  In response to a request from the central processing unit 33, the coordinate receiving unit 32 transmits an operation state and pressed coordinate acquisition request to the coordinate transmitting unit 24 on the touch panel controller 2 side, and receives the operation state and the pressed coordinate.

  The icon management unit 36 manages icons arranged on the screen of the display unit 4. The icon here refers to a power button for switching the power state of the electric device when the user presses on the touch panel 1, a strength button for switching the strength of the operation output, and the like. In the icon management means 36, the image data of the icon, the current operation state (release, pressing start and pressing) of the icon, display coordinates indicating the position currently displayed on the display means 4, and the icon can be clicked. An operation attribute indicating whether drag movement is possible is stored for each icon. The contents of the icon management means 36 are updated in real time by the central processing means 33.

  The interrupt mode determination unit 35 searches the icon management unit 36 for an icon arranged at the pressed coordinate received from the central processing unit 33, determines the interrupt mode based on the operation attribute of the icon, and the interrupt The mode is output to the interrupt mode setting means 25 included in the touch panel controller 2.

  The display control unit 37 displays an image such as a background image on the display unit 4 according to an instruction from the central processing unit 33. Further, in accordance with an instruction from the central processing means 33, the icon image displayed on the display means 4 is changed based on the operation state and operation attribute of the icon managed by the icon management means 36. For example, when the operation state of the icon whose operation attribute is “drag moveable” is “pressing”, the icon image appears to float from the background with a shadow as shown in FIG. 9B described later. And an image different from the image when the icon is “release” (FIG. 9A) is displayed. In addition to adding a shadow, the image may be drawn by slightly swinging up and down, left and right, or may be drawn by changing the color scheme or shading of the icon image or the line type of the frame line.

  The display means 4 is a display that displays images and characters.

FIG. 9 shows an example of a display screen displayed on the display means. FIG. 9A is a screen showing a “release” state where the touch panel is not pressed, and FIG. 9B is a diagram showing a “pressing” state where the touch panel is pressed.
A plurality of icons 100 (100a, 100b) are displayed on the display screen. Among the icons 100, 100a is an icon that can be dragged, and 100b is an icon that cannot be dragged (clickable). FIG. 9B shows a state in which the “1F distribution board trip” icon is pressed, and black shadows are added to the left and bottom of the icon, indicating that dragging is possible.

  The communication unit 5 is connected to an electrical device via a network, and exchanges control information with the electrical device in response to a request from the central processing unit 33.

  Next, the operation of the touch panel controller 2 in the display operation device according to the second embodiment will be described.

FIG. 10 is a flowchart showing the operation of the touch panel controller 2 in the display operation device of the second embodiment.
After the power is turned on, the touch panel controller 2 checks whether or not a press on the touch panel 1 is detected by the press detection means 21 using the interrupt control means 23 (S31), and waits until a press is detected. That is, the press detection unit 21 detects a pressing state (starting pressing or pressing) on the touch panel 1 and outputs the detection result to the interrupt control unit 23 via the operation state detection unit 26. The control means 23 checks whether or not a press on the touch panel 1 is detected according to the result from the press detection means 21. Here, when the touch panel 1 is pressed, the operation state detection unit 26 changes the operation state from “release” to “start pressing” based on the output from the press detection unit 21, and starts pressing. Is output to the interrupt control means 23.

  The interrupt control means 23 receives the fact that the detection result of the operation state detection means 26 has been changed to “start pressing”, determines that the touch panel 1 has been pressed, and starts outputting an interrupt signal (S32).

  Then, the coordinate transmission unit 24 waits for an operation state and a press coordinate acquisition request output from the coordinate reception unit 32 of the CPU 3 when the interrupt control unit 23 outputs an interrupt signal to the CPU 3. If the request is received (S33), the operation state detected by the operation state detection unit 26 and the pressed coordinates detected by the press detection unit 21 are output to the coordinate receiving unit 32 on the CPU 3 side (S34). Then, after completing the output of the operation state and the pressed coordinates, the coordinate transmission unit 24 instructs the interrupt control unit 23 to stop outputting the interrupt signal. Receiving the instruction, the interrupt control means 23 stops the interrupt signal (S35).

  Then, the interrupt control unit 23 checks the interrupt mode at this time with reference to the interrupt mode setting unit 25 (S36), and in the case of the “detail mode”, the current operation state of the touch panel 1 is detected as the operation state. A check is made based on the detection result of the means 26 (S37). When the current operation state of the touch panel 1 is “pressing”, the process returns to step S32, and the processes of steps S32 to S37 are repeated until the operation state of the touch panel 1 becomes “release”. As a result, when the interrupt mode is “detail mode”, the pressed coordinates detected by the press detection means 21 are sequentially transmitted to the CPU 3 side from when the touch panel 1 is started to be released. Become.

  On the other hand, if the interrupt mode is “simple mode” in step S36, the process returns to the first step S31. As a result, if the touch panel 1 is pressed and the interrupt mode corresponding to the pressed coordinates is “simple mode”, the pressed coordinates are transmitted after the pressed coordinates are once transmitted to the CPU 3 in step S34. Without waiting for the next press.

Next, the operation of the CPU 3 in the display operation device of the present embodiment will be described.
FIG. 11 is a flowchart showing the operation of the CPU 3 in the display operation device according to the second embodiment.

  After the CPU 3 is turned on, initialization processing such as display of an initial screen on the display means 4, initialization of the communication means 5, and initial setting of the interrupt mode to the “simple mode” is performed (S41), and then the main processing is performed. Start up (S42).

  The central processing means 33 executes main processing, and performs communication processing with control information with the electric equipment, update processing of display contents on the display means 4 via the display control means 37 based on the control information, and the like. Repeatedly. In the main process, it is monitored that the operation state and the pressed coordinates from the touch panel controller 2 are stored in the buffer 33a. If the pressed coordinates are not stored in the buffer 33a (S43), the main process is performed. It continues (S44), and when the pressed coordinate is stored in the buffer 33a, the pressed coordinate process is performed (S45).

  By the way, when the touch panel controller 2 detects that the touch panel 1 is pressed, the touch panel controller 2 starts outputting an interrupt signal to the CPU 3 (step S32 in FIG. 10). When the start of output is detected, interrupt processing is performed.

FIG. 12 is a flowchart showing the flow of interrupt processing.
When the interrupt receiving means 34 of the CPU 3 detects the start of the output of the interrupt signal output from the interrupt control means 23 of the touch panel controller 2 (S51), it notifies the central processing means 33 of the detection, and the central processing means 33 In 33, the main process being executed in step S42 is interrupted (S52), and the coordinate acquisition process is started (S53).

FIG. 13 is a flowchart showing the flow of the coordinate acquisition process of FIG.
In the coordinate acquisition process, the central processing means 33 requests the touch panel controller 2 for the operation state and the pressed coordinates via the coordinate receiving means 32 (S53a), and the pressed coordinates transmitted from the touch panel controller 2 in response to the request are obtained. Receive (S53b). Then, the pressed coordinates are stored in the internal buffer 33a (S53c), and the coordinate acquisition process is terminated.

  When completing the coordinate acquisition process, the central processing means 33 resumes the main process from the interrupted process, that is, the point interrupted before the coordinate acquisition process (S54).

  Note that, when the operation state and the pressed coordinates are stored in the buffer 33a as described above, the CPU 3 performs the pressed coordinate processing based on the operation state and the pressed coordinates. Hereinafter, the pressed coordinate processing will be described.

FIG. 14 is a flowchart showing the flow of the pressed coordinate processing.
When the operation state stored in the buffer 33a is “start pressing” (S45a), the central processing unit 33 performs a process corresponding to the icon arranged at the pressed coordinates stored in the buffer 33a (S45b). Then, the central processing means 33 notifies the interrupt mode determining means 35 of the pressed coordinates stored in the buffer 33a. The interrupt mode determination unit 35 searches the icon management unit 36 for an icon arranged at the pressed coordinate received from the central processing unit 33, and when the operation attribute of the icon is “drag moveable”, the interrupt mode is set. The “detailed mode” is determined, and in other cases, the “simple mode” is determined and output to the interrupt mode setting means 25 of the touch panel controller 2 (S45c).

  When the operation state in the buffer 33a is “start pressing”, the central processing unit 33 instructs the icon management unit 36 to indicate the operation state of the icon in which the pressed coordinates in the buffer 33a are arranged. (S45d). This operation state returns to “Release” when no pressed coordinates are received for a certain period of time or when the pressed coordinates corresponding to “Start pressing” are received next.

  On the other hand, when the operation state in the buffer 33a is “pressing”, the central processing unit 33 instructs the icon management unit 36 to display the “display coordinates” of the icon where the pressed coordinates in the buffer 33a are arranged. The pressed coordinates stored in the buffer 33a are changed (S45e). The central processing means 33 instructs the display control means 37 to redraw the icon whose display coordinates have been changed by changing the display coordinates (S45f). The central processing means 33 instructs the display control means 37 to shadow the icon image for the icon whose operation attribute is “drag moveable” and whose operation state is “pressing”. To make it appear to float.

  According to the second embodiment, the interrupt mode is determined according to the operation attribute of the icon arranged at the pressed coordinate of touch panel 1, and the CPU controls the number of times the interrupt process is activated according to the interrupt mode. As a result, it is possible to control the start of interrupt processing under the initiative of the CPU, and it is possible to select flexibly according to the pressing operation on the touch panel whether priority is given to the number of pressed coordinates or priority to reduce the CPU processing load. It becomes. Specifically, when an icon that cannot be dragged, such as a background image or a decision button, is pressed by the user, the interrupt mode is set to “simple mode”, and the interrupt process is started only at the first press, The number of times the coordinate acquisition process is activated can be suppressed. Therefore, the CPU processing load can be suppressed, and the influence of the coordinate acquisition process on other processes can be avoided.

  On the other hand, when an icon that can be dragged is pressed by the user, the interrupt mode is set to the “detail mode” to prioritize the interrupt process. That is, the pressed coordinates are acquired at regular intervals. Thereby, it is possible to perform drawing in which the icon is moved following the drag operation.

  Further, in a general display operation device that includes a mouse like a personal computer and moves the mouse cursor following the user's mouse operation, the mouse cursor image is changed when a draggable icon image is selected (for example, normally an arrow is used). The user can easily recognize that the selected icon can be dragged by pressing the palm of the hand when pressed, but the display operation device having the touch panel as in this example does not include a mouse. In many cases, it is difficult for the user to recognize that the selected icon can be dragged.

  However, in the second embodiment, since the operation state and the operation attribute are managed for each icon, when a clickable icon is simply clicked, for example, a palm is displayed and can be dragged. When a simple icon is in a pressed state, it is possible to draw with a different expression from the normal time, such as adding a shadow to the icon or slightly shaking it. This makes it easy for the user to recognize that the pressed icon can be dragged.

Embodiment 3 FIG.
In the display operation device according to the third embodiment, the CPU changes the transfer speed when transmitting the pressed coordinates from the touch panel controller 2 to the CPU 3 according to the operation attribute of the icon arranged at the pressed coordinates. This adjusts the acquisition interval.

FIG. 15 is a block diagram of the display operation device according to the third embodiment.
15 includes a touch panel controller 2, a touch panel controller 2 including a press detection unit 21, an interrupt control unit 23, a coordinate transmission unit 24, and an operation state detection unit 26, a coordinate reception unit 32, a central calculation unit 33, The CPU 3 includes an interrupt reception unit 34, an icon management unit 36, a display control unit 37, a transfer rate setting unit 38, and an abnormality detection unit 39, a display unit 4, and a communication unit 5.

  The touch panel 1 is an interface that accepts a pressing operation by an input means such as a user's finger and pen, and is formed on the screen of the display means 4.

Hereinafter, the configuration of the touch panel controller 2 will be described first.
The press detection unit 21 detects that the touch panel 1 is pressed, outputs the pressed state to the operation state detection unit 26, and coordinates the pressed coordinates in response to a request from the coordinate transmission unit 24. Output to the transmission means 24.

  The operation state detection unit 26 detects the operation state of the user with respect to the touch panel 1 based on the detection result of the press detection unit 21. The operation states include “release”, “pressing start”, and “pressing”, and each represents a state where the touch panel 1 is not pressed, a state where pressing is started, and a state where pressing continues without being released. .

  The interrupt control unit 23 outputs an interrupt signal to the CPU 3 when the press detection unit 21 detects a press operation on the touch panel 1. Further, the interrupt control means 23 stops outputting the interrupt signal when receiving an instruction to stop the interrupt signal output from the coordinate transmitting means 24 after the output of the interrupt signal is started.

  The coordinate transmission unit 24 exchanges data with the coordinate reception unit 32 of the CPU 3 by a clock synchronous serial communication method. In the clock synchronous serial communication system, the coordinate transmission unit 24 and the coordinate reception unit 32 are connected by three signal lines of a clock signal line, a transmission signal line, and a reception signal line, and the coordinate reception unit 32 is placed on the clock signal line. The command data is transmitted from the CPU 3 to the touch panel controller 2 on the transmission signal line at the timing of the transmitted clock, and the pressed coordinates are output bit by bit from the touch panel controller 2 to the CPU 3 on the reception signal line. After receiving the command data requesting the pressed coordinates from the coordinate receiving means 32, the coordinate transmitting means 24 acquires the pressed coordinates from the pressing detection means 21, and outputs the pressed coordinates to the reception signal line at the timing of the clock. Further, after the output of the pressed coordinates is completed, the interrupt control means 23 is instructed to stop the output of the interrupt signal.

Next, the configuration of the CPU 3 will be described.
The central processing means 33 performs software processing in the display operation device. Software processing is classified into main processing that is normally executed and interrupt processing that is executed when an external event occurs. In the main processing, based on the pressed coordinates received by the coordinate receiving means 32, the display content displayed on the display means 4 is updated via the display control means 37, the transfer coordinates setting means 38 notifies the pressed coordinates, and the icon. An operation state of the icons managed by the management means 36 and the coordinates at which the icons are arranged are updated, and communication processing for performing control information exchange with the electric device via the communication means 5 is performed. The interrupt process is a process that is started when an interrupt signal is received from the touch panel controller 2 via the interrupt reception unit 34, and the operation state and the operation state from the coordinate transmission unit 24 of the touch panel controller 2 via the coordinate reception unit 32. A process for acquiring the pressed coordinates is performed.

  Further, when the interrupt receiving means 34 detects an interrupt signal during execution of the main process, the central processing means 33 interrupts the main process and starts the interrupt process. Then, after the interruption process is completed, the interrupted main process is resumed.

  The interrupt receiving unit 34 detects an interrupt signal output from the interrupt control unit 23 of the touch panel controller 2 and a reception completion interrupt signal described later output when the coordinate receiving unit 32 completes reception of the pressed coordinate, The central processing means 33 is notified of the detection.

  In response to a request from the central processing unit 33, the coordinate receiving unit 32 transmits an operation state and pressed coordinate acquisition request to the coordinate transmitting unit 24 on the touch panel controller 2 side, and receives the operation state and the pressed coordinate. In this reception operation, the output of the pressed coordinate request command to the coordinate transmission means 24 of the touch panel controller 2, the reception of the pressed coordinates output from the coordinate transmission means 24, and the clock transmission on the clock signal line that is the output timing of the command and the pressed coordinates. I do. The frequency at which the clock is transmitted follows the transfer rate set by transfer rate setting means 38 described later.

  The icon management unit 36 manages icons arranged on the screen of the display unit 4. The icon here refers to a power button for switching the power state of the electric device when the user presses on the touch panel, a strength button for switching the strength of the operation output, and the like. In the icon management means 36, the image data of the icon, the current operation state (release, pressing start and pressing) of the icon, display coordinates indicating the position currently displayed on the display means 4, and the icon can be clicked. An operation attribute indicating whether drag movement is possible is stored for each icon. The contents of the icon management means 36 are updated in real time by the central processing means 33.

  The transfer speed setting unit 38 searches the icon management unit 36 for an icon arranged at the pressed coordinate received from the central processing unit 33, and receives the operation state and the pressed coordinate from the touch panel controller 2 based on the operation attribute of the icon. The transfer speed at the time of the transmission, specifically, the frequency at which the coordinate receiving means 32 transmits the clock on the clock signal line is set. This transfer speed is set faster when the operation attribute is “drag moveable” than when it is “clickable”.

  The anomaly detection means 39 stores the pressed coordinates collected during the last day as a history, calculates the average coordinates of the pressed coordinates from the history, and the average coordinates and the reference coordinates set at the time of shipment of the display operation device When the difference is equal to or greater than the threshold, it is detected that a hardware abnormality has occurred on the touch panel. In this case, when the average coordinate is away from the reference coordinate, it is determined that the pressed coordinate cannot be detected correctly, and it is determined that a hardware abnormality has occurred.

  The display control unit 37 displays an image such as a background image on the display unit 4 according to an instruction from the central processing unit 33. Further, in accordance with an instruction from the central processing means 33, the icon image displayed on the display means 4 is changed based on the operation state and operation attribute of the icon managed by the icon management means 36. For example, when the operation state of the icon whose movement attribute is draggable is “pressing”, the icon image is drawn so as to appear to float from the background with a shadow as shown in FIG. , An image different from that when no icon is selected is displayed. In addition to adding a shadow, the image may be drawn by slightly swinging up and down, left and right, or may be drawn by changing the color scheme or shading of the icon image or the line type of the frame line. Further, when the abnormality detection means 39 detects an abnormality of the touch panel 1, an abnormality notification LED (not shown) provided on the display means 4 is blinked.

  The display means 4 is a display that displays images and characters. In addition, an abnormality notification LED (not shown) for notifying the user of an abnormality of the touch panel is provided.

  The communication unit 5 is connected to an electrical device via a network, and exchanges control information with the electrical device in response to a request from the central processing unit 33.

  Next, the operation of the touch panel controller 2 in the display operation device of the present embodiment will be described.

FIG. 16 is a flowchart illustrating the operation of the touch panel controller 2 in the display operation device according to the third embodiment.
After the power is turned on, the touch panel controller 2 checks whether or not a press on the touch panel 1 is detected by the press detection means 21 using the interrupt control means 23 (S61), and waits until a press is detected. That is, the press detection unit 21 detects the pressing state on the touch panel 1 and outputs the detection result to the interrupt control unit 23 via the operation state detection unit 26. The interrupt control unit 23 It is checked whether or not a press on the touch panel 1 is detected according to the result from the press detection means 21. Here, when the touch panel 1 is pressed, the operation state detection unit 26 changes the operation state from “release” to “start pressing” based on the output from the press detection unit 21, and starts pressing. Is output to the interrupt control means 23.

  The interrupt control means 23 receives that the detection result of the operation state detection means 26 has been changed to “start pressing”, determines that the touch panel 1 has been pressed, and starts outputting an interrupt signal (S62).

  Then, the coordinate transmission means 24 continues to wait for the operation state and pressed coordinate acquisition request output from the coordinate receiving means 32 of the CPU 3 by outputting the interrupt signal from the interrupt control means 23 to the CPU 3 side. Is received (S63), the pressed coordinates detected by the pressing detection means 21 are output to the reception signal line according to the clock transmitted by the coordinate receiving means 32 (S64). Then, after completing the output of the operation state and the pressed coordinates, the coordinate transmission unit 24 instructs the interrupt control unit 23 to stop outputting the interrupt signal. Receiving the instruction, the interrupt control means 23 stops the interrupt signal (S65).

Next, the operation of the CPU 3 in the display operation device of the present embodiment will be described.
FIG. 17 is a flowchart illustrating the operation of the CPU 3 in the display operation device according to the third embodiment.

  After the CPU 3 is turned on, initialization processing such as display of an initial screen on the display means 4, initialization of the communication means 5, and initial setting of the transfer rate to 1 MHz is performed (S71), and then the main process is started (S72). ).

  The central processing means 33 executes main processing, and performs communication processing with control information with the electric equipment, update processing of display contents on the display means 4 via the display control means 37 based on the control information, and the like. Repeatedly. In the main process, it is monitored that the operation state and the pressed coordinates from the touch panel controller 2 are stored in the buffer 33a. If the pressed coordinates are not stored in the buffer 33a (S73), the main process is performed. It continues (S74), and when the pressed coordinate is stored in the buffer 33a, the pressed coordinate process is performed (S75).

  By the way, when the touch panel controller 2 detects that the touch panel 1 is pressed, the touch panel controller 2 starts outputting an interrupt signal to the CPU 3 (Step S62 in FIG. 16). When the start of output is detected, interrupt processing is performed.

FIG. 18 is a flowchart showing the flow of interrupt processing.
When the interrupt receiving means 34 of the CPU 3 detects the start of the output of the interrupt signal output from the interrupt control means 23 of the touch panel controller 2 (S81), it notifies the central processing means 33 of the detection, and the central processing means 33 In 33, the main process being executed in step S72 is interrupted (S82), and the coordinate acquisition process is started (S83).

FIG. 19 is a flowchart showing the flow of the coordinate acquisition process of FIG.
In the coordinate acquisition process, the central processing unit 33 requests the operation state and the pressed coordinates from the touch panel controller 2 via the coordinate receiving unit 32 (S83a). Then, the main process is resumed from the point interrupted in step S82 (S83b). At this time, the central processing unit 33 executes the main process, but the coordinate receiving unit 32 performs a process of acquiring the operation state and the pressed coordinates from the touch panel controller 2 according to the set transfer speed (S83c). When the reception of the operation state and the pressed coordinates is completed, the coordinate receiving unit 32 outputs a reception completion interrupt signal to the interrupt receiving unit 34. When detecting the reception completion interrupt signal, the interrupt receiving unit 34 notifies the central processing unit 33 of the detection.

  When the central processing unit 33 receives the reception completion interrupt signal from the interrupt receiving unit 34, the central processing unit 33 interrupts the main process being executed (S83d), and stores the operation state and pressed coordinates received by the coordinate receiving unit 32 in the buffer 33a. Store (S83e) and end the coordinate acquisition process.

  When the interrupt processing is finished, the central processing means 33 resumes the main processing from the interrupt end processing, that is, the point interrupted in step S83d (S84).

  When the operation state and the pressed coordinates are stored in the buffer 33a as described above, the CPU 3 performs a pressed coordinate process (step S75 in FIG. 17) based on the operated state and the pressed coordinates. Will be described.

FIG. 20 is a flowchart showing the flow of the pressed coordinate processing.
The central processing means 33 first notifies the abnormality detection means 39 of the pressed coordinates. The abnormality detection unit 39 accumulates the pressed coordinates notified from the central processing unit 33 as a history, calculates an average value of the pressed coordinates acquired from the present day to the previous day, and calculates the average value and the input operation device. It is determined whether or not the difference between the basic coordinate values set at the time of shipment is greater than or equal to a threshold value (S75a). If it is equal to or greater than the threshold value, it is detected that a hardware abnormality has occurred in the touch panel 1, and the abnormality detection LED of the display means 4 is turned on via the display control means 37 (S75b).

  Next, when the operation state in the buffer 33a is “depressing” (S75c), the central processing unit 33 subsequently sets the operation attribute of the icon displayed at the position of the pressed coordinate in the buffer 33a to “drag. It is checked whether or not “movable” (S75d). If “drag movement is possible”, the “display coordinates” in the icon management means 36 of the icon is changed to the pressed coordinates stored in the buffer 33a (S75e). Then, the display control means 37 is caused to redraw the icon at the new display coordinate position (S75f).

  On the other hand, when the operation state in the buffer 33a is “start pressing”, the central processing means 33 subsequently determines whether the operation attribute of the icon displayed at the pressed coordinate position in the buffer 33a is “drag moveable”. If it is “drag moveable”, the operation state of the icon is instructed to the icon management means 36 and changed to “pressing” (S75h). Further, the central processing means 33 instructs the display control means 37 to draw the icon image so as to appear as if it is floating from the background with a shadow (S75i). Further, the pressed coordinates in the buffer 33a are output to the transfer speed setting means 38.

  When the transfer speed setting unit 38 receives the pressed coordinate from the central processing unit 33, the transfer speed setting unit 38 searches the icon management unit 36 for an icon arranged at the pressed coordinate, and the operation attribute of the icon (here, “drag movement is possible”). ) Is set to, for example, “100 KHz” (S75j). That is, when the icon pressed on the touch panel 1 is an “drag moveable” icon, the CPU 3 performs interrupt processing (coordinate acquisition processing) in preference to other processing. As a result, the position of the pressed coordinates that change with the drag operation can be acquired at short time intervals, and the icon image can be displayed to move with the drag operation.

  On the other hand, when the operation attribute is “clickable” in step S75g, the central processing means 33 outputs the pressed coordinates in the buffer 33a to the transfer speed setting means 38 as described above. The transfer speed setting means 38 receives the pressed coordinates from the central processing means 33, and here, since the operation attribute of the icon is “clickable”, the transfer speed is set to a transfer speed corresponding to the clickable, for example, “10 KHz”. (S75k). That is, when the click is possible, it is not necessary to acquire the pressed coordinates at short time intervals as compared with the case where the drag movement is possible. Thereby, CPU3 can reduce the frequency | count of the acquisition process of a pressing coordinate, and can process a main process other than an interruption process with priority on CPU3 side.

  According to the third embodiment, the CPU 3 sets the transfer speed when transmitting the pressed coordinates from the touch panel controller 2 to the CPU 3 according to the operation attribute of the icon arranged at the pressed coordinates. The activation control of the interrupt processing can be led by the CPU. In addition, by controlling the transfer speed, the number of interrupt processing activations can be controlled, and whether to obtain priority for the number of pressed coordinates or to reduce the CPU processing load can be flexibly selected according to the pressing operation on the touch panel. It becomes possible. Specifically, when an icon whose operation attribute is clickable is pressed by the user, the number of interrupt processing activations can be suppressed by setting the transfer speed slower. Therefore, the CPU processing load can be suppressed, and the influence of the coordinate acquisition process on other processes can be avoided.

  On the other hand, when a draggable icon is pressed by the user, by setting the transfer speed faster, the number of times the interrupt process is started can be increased and the interrupt process can be preferentially processed. Thereby, it is possible to perform drawing in which the icon is moved following the drag operation.

  Further, in a general display operation device that includes a mouse like a personal computer and moves the mouse cursor following the user's mouse operation, the mouse cursor image is changed when a draggable icon image is selected (for example, normally an arrow is used). The user can easily recognize that the currently selected icon can be moved by dragging, but the display operation device having the touch panel as in this example does not include a mouse. In many cases, it is difficult for the user to recognize that the selected icon can be dragged.

  However, in the third embodiment, since the operation state and the operation attribute are managed for each icon, when a clickable icon is simply clicked, for example, a palm is displayed and can be dragged. When a simple icon is in a pressed state, it is possible to draw with a different expression from the normal time, such as adding a shadow to the icon or slightly shaking it. This makes it easy for the user to recognize that the pressed icon can be dragged.

  Further, by collecting the history of the pressed coordinates, it is possible to detect a hardware abnormality of the touch panel 1 and prompt the user to quickly repair or replace the display operation device.

The present invention is not limited to the above-described embodiment, and for example, the following modifications are possible.
1. In the first embodiment, the determination of the interrupt interval by the interrupt interval determination unit 31 is performed according to the input method, and is arranged at the position of the pressed coordinate detected by the press detection unit 21. It is determined according to the operation attribute of the icon.
2. In the second embodiment, the determination of the interrupt mode by the interrupt mode determination unit 35 is determined according to the operation attribute of the icon arranged at the pressed coordinate position detected by the press detection unit 21.
