  As will be described in detail later, when receiving a collective drawing instruction on the display screen from the central processing unit 41, the drawing calculation device 42 sequentially reads element information from the screen configuration table 402 corresponding to the display screen to be updated. Then, the drawing calculation device 42 draws an element image corresponding to the read element information. The element information includes at least one element candidate.

  When the read element information includes a plurality of element candidates, the drawing operation device 42 outputs an inquiry signal to the central operation device 41 to inquire which element candidate should be selected. Based on the response data transmitted from the central processing unit 41 in response to such an inquiry, the drawing processing unit 42 selects one of the plurality of element candidates and based on the selected element candidate. Draw element images. On the other hand, when there is one element candidate included in the read element information, the image calculation device 42 draws an element image based on the element candidate without making an inquiry to the central calculation device 41.

  An example of the screen configuration table 402 is shown in FIG. The screen configuration table 402 shown in FIG. 3 corresponds to the comfort selection screen (see FIG. 4). In this screen configuration table 402, No. Six pieces of element information 1 to 6 are registered.

The drawing area information includes a drawing start position (x: horizontal position, y: vertical position), a horizontal width (dx), and a vertical width (dy). ").

  Returning to FIG. 1, the central processing unit 41 is a microcomputer that controls the operation of a device to be controlled such as an air conditioner or changes the content displayed on the display device 3 in accordance with the content operated by the user. is there.

  As shown in FIG. 6, the central processing unit 41 stores a control unit 410 that centrally controls the central processing unit 41, a communication unit 411 for communicating with the drawing processing unit 42, and various tables that will be described later. A data storage unit 412, a ROM 413 that stores a program, data used when the program is executed, a RAM 414 used as a work area of the control unit 410, and an operation signal output from the operation reception unit 2 are input. An input port 415.

  In addition to the above-described components, the central processing unit 41 includes an interface (not shown) for communicating with a control target device such as an air conditioner.

  The control unit 410 includes a CPU (Central Processing Unit) and the like, interprets a program read from the ROM 413, and performs arithmetic processing and controls each component according to the contents. As shown in FIG. 7, the control unit 410 includes a batch drawing instruction unit 4100, an individual drawing instruction unit 4101, and an inquiry handling unit 4102 as functions unique to the present invention.

  The batch drawing instruction unit 4100 (first drawing instruction unit) determines whether or not the display screen needs to be updated when there is a user operation or when there is a change in specific information to be managed. The specific information includes, for example, measurement values such as the current time (in minutes) and a temperature sensor. When the display screen needs to be updated, the batch drawing instruction unit 4100 instructs the drawing arithmetic unit 42 to batch display the display screen.

  When the individual drawing instruction unit 4101 receives an interruption signal indicating interruption of batch drawing from the drawing arithmetic unit 42, the individual drawing instructing unit 4101 sequentially instructs the drawing arithmetic unit 42 to draw character strings set by the user by character.

  When receiving the above-mentioned inquiry signal from the drawing operation device 42, the inquiry corresponding unit 4102 generates response data for the inquiry based on the current time and control state, and sends the generated response data to the drawing operation device 42. Send.

  The data storage unit 412 is a readable / writable nonvolatile memory composed of, for example, a flash memory. As illustrated in FIG. 8, the data storage unit 412 stores an update condition table 4120, a query interpretation table 4121, and a user setting image table 4122.

  The update condition table 4120 is a data table in which conditions regarding display screen update are defined. The update condition table 4120 includes, for example, information indicating the relationship between the user operation content and the display screen transition. The update condition table 4120 shows the relationship between the user's operation content and the display screen to be redrawn, and the relationship between the change in the current time and the change in the measured value of the temperature sensor and the display screen to be redrawn. Contains information.

  More specifically, in the update condition table 4120, for example, when “comfort selection” is selected as the operation mode by the user while the “operation setting screen” is displayed, the “comfort selection screen” (see FIG. 4). Information indicating switching to is included. Also, for example, if the current time (in minutes) changes while the “operation setting screen” is displayed, the “operation setting screen” may be redrawn, or the menu item may be changed by the user while the “comfort selection screen” is displayed. When the selection operation is performed, information indicating that the “comfort selection screen” is redrawn is included.

  The query interpretation table 4121 is a data table that is referred to by the query handling unit 4102 to interpret the content of the query from the drawing arithmetic device 42. More specifically, in the query interpretation table 4121, as shown in FIG. 9, information in which the number of queries from the drawing arithmetic unit 42 and the query contents are associated is registered for each display screen. For example, when a first inquiry signal is received from the drawing operation device 42 during batch drawing on the comfort select screen, it is indicated that the inquiry is an inquiry related to cursor drawing. Further, when a second inquiry is received from the drawing operation device 42 during the batch drawing of the comfort selection screen, it is indicated that the inquiry is an inquiry related to the drawing of the explanatory pattern.

  Returning to FIG. 8, the user setting image table 4122 is a data table in which information on an arbitrary character string set by the user is registered. The user can set an arbitrary name (for example, “Dad's study”) as the room name on the operation setting screen. In addition, the user can set an arbitrary name (for example, “dad”) as the setting name on the comfort selection screen.

  In the user setting image table 4122, information (set character string information) related to the name (character string) arbitrarily set by the user as described above is registered for each display screen. As shown in FIG. 10, the set character string information includes a font ID, a character code string, a starting point of a drawing area, a maximum number of characters, and an arrangement mode. The font ID is an ID (identification) indicating a font type, and is selected by a user when inputting a character string from among a plurality of font types prepared in advance. The character code string indicates a character string input by the user. The starting point of the drawing area indicates the position that is the starting point (starting point) of the drawing area where the character string can be displayed. This position is uniquely determined according to the display screen, and is automatically set by the control unit 410 when the user inputs a character string.

  The maximum number of characters indicates the maximum number of characters that can be set by the user and is uniquely determined according to the display screen, and is automatically set by the control unit 410 when the user inputs a character string. The arrangement mode is selected by the user when inputting a character string from among “left justified”, “centering”, and “right justified”.

  When receiving the interruption signal from the drawing calculation device 42, the individual drawing instruction unit 4101 draws a drawing of each character of a character string (for example, “dad”) set by the user according to the registered contents of the user setting image table 4122. The device 42 is instructed sequentially.

  FIG. 11 is a flowchart illustrating a procedure of processing (drawing instruction processing) executed by the control unit 410 of the central processing unit 41. This drawing instruction process is repeatedly executed at a predetermined cycle.

  The batch drawing instruction unit 4100 determines whether or not the display screen needs to be updated (update necessity) (step S101). For example, when there is an operation by the user, the collective drawing instruction unit 4100 refers to the update condition table 4120 based on the information (for example, screen No.) for specifying the currently displayed display screen and the content of the operation. Thus, it is determined whether or not the display screen needs to be updated (ie, display screen switching or redrawing). Alternatively, when there is a change in the current time (in minutes), the update condition table 4120 is referenced to determine whether or not redrawing of the currently displayed display screen is necessary.

  When it is determined that the display screen needs to be updated (step S102; YES), the batch drawing instruction unit 4100 instructs the drawing arithmetic unit 42 to batch display the display screen (step S103). At this time, the batch drawing instruction unit 4100 receives a drawing command (first command) that stores information indicating a batch drawing instruction and the storage destination (memory address) of the screen configuration table 402 corresponding to the display screen to be updated. Generate. Then, the batch drawing instruction unit 4100 transmits the generated drawing command to the drawing arithmetic device 42 via the communication unit 411. In the data storage unit 412 of the central processing unit 41, a data table (not shown) in which information for specifying the display screen (for example, screen No.) is associated with the storage location of the screen configuration table 402 is stored in advance. It is remembered. After instructing batch drawing, the control unit 410 ends the drawing instruction processing in this cycle.

  When the interruption signal is received from the drawing arithmetic unit 42 (step S104; YES), the individual drawing instruction unit 4101 executes individual drawing instruction processing (step S105). Details of the individual drawing instruction process will be described later. After the completion of the individual drawing instruction process, the control unit 410 ends the drawing instruction process in this cycle.

  When the display screen does not need to be updated (step S102; NO) and no interruption signal has been received (step S104; NO), and no inquiry signal has been received from the drawing arithmetic unit 42 (step S106; NO). The control unit 410 ends the drawing instruction process in this cycle. On the other hand, when an inquiry signal is received from the drawing operation device 42 (step S106; YES), the inquiry corresponding unit 4102 generates response data for the inquiry, and the generated response data is sent to the drawing operation device 42 via the communication unit 411. (Step S107). More specifically, the inquiry handling unit 4102 displays the screen No. of the display screen during batch drawing. And the query interpretation table 4121 on the basis of the number of queries after instructing batch drawing, and interprets the contents of the query. Then, the inquiry corresponding unit 4102 acquires information corresponding to the interpreted content.

  For example, when the inquiry indicates a drawing of the current time (minute) on the operation setting screen, the inquiry corresponding unit 4102 acquires a current time (minute) (not shown) from the clock function provided in the central processing unit 41. Alternatively, when the inquiry indicates the drawing of the cursor on the comfort selection screen, the inquiry corresponding unit 4102 reads the comfort from the data table (not shown) for managing the control state stored in the data storage unit 412. The menu item selected by the user on the select screen is acquired.

  The inquiry handling unit 4102 displays the element candidate No. corresponding to the information acquired as described above. Is determined. For example, when the inquiry from the drawing arithmetic unit 42 indicates the drawing of the cursor, and “I want to sterilize and deodorize” is selected in the menu item of the comfort selection screen (see FIG. 4), the determination is made. Element candidate No. Becomes “1”.

  The inquiry corresponding unit 4102 receives the element candidate No. determined as described above. Is transmitted to the drawing arithmetic unit 42. After transmitting the response data, the control unit 410 ends the drawing instruction process in this cycle.

  FIG. 12 is a flowchart showing the procedure of the individual drawing instruction process executed by the individual drawing instruction unit 4101 of the control unit 410. The individual drawing instruction unit 4101 reads set character string information corresponding to the display screen during batch drawing from the user setting image table 4122. Then, one character code is acquired from the beginning of the character code string included in the read set character string information (step S201).

  The individual drawing instruction unit 4101 calculates the storage destination (memory address) of the font data corresponding to the acquired character code (step S202). At this time, the individual drawing instruction unit 4101 determines the font data corresponding to the character code based on the storage destination of the font table 401 determined from the font ID included in the read set character string information and the acquired character code. Calculate the storage location of. Specifically, when the character codes are stored in ascending order in the font table 401, the storage destination of the font data is calculated by the following formula 1.

(Formula 1)
Font data storage location = font table 401 storage location + character code storage order N × individual font data size

  In the above equation 1, N = 0, 1, 2,..., And the individual font data size is the same for each font data (for example, 32 bytes) for the same font ID. A data table (not shown) in which the font ID, the storage location of the font table 401, and the individual font data size are associated with each other is stored in advance in the data storage unit 412 of the central processing unit 41.

  Next, the individual drawing instruction unit 4101 calculates the drawing start position of the character corresponding to the acquired character code (step S203). Specifically, when the arrangement mode is “right-justified”, the drawing start position (X) of each character is calculated by the following Expression 2. When the arrangement mode is “left-justified”, the drawing start position (X) of each character is calculated. ) Is calculated by Equation 3 below. The drawing start position (Y) is the same as the starting point (y) of the drawing area regardless of the arrangement mode.

(Formula 2)
X = starting point of drawing area (x) + (maximum number of characters-number of drawn characters + character order N-1) x font width

(Formula 3)
X = starting point of drawing area (x) + (order of characters N-1) x font width

  In the above formulas 2 and 3, N = 0, 1, 2,.

  The individual drawing instruction unit 4101 instructs the drawing arithmetic device 42 to draw an individual character corresponding to the acquired character code (step S204). At this time, the individual drawing instruction unit 4101 generates a drawing command (second command) that stores information indicating an individual drawing instruction and the font data storage destination and drawing start position calculated as described above. To do. Then, the individual drawing instruction unit 4101 transmits the generated drawing command to the drawing calculation device 42 via the communication unit 411.

  If acquisition of all character codes from the character code string has not been completed (step S205; NO), the processing of the individual drawing instruction unit 4101 returns to step S201. On the other hand, when the acquisition of all the character codes from the character code string is completed (step S205; YES), the individual drawing instruction unit 4101 instructs the drawing arithmetic unit 42 to resume batch drawing (step S206). At this time, the individual drawing instruction unit 4101 generates a drawing command (third command) that stores information indicating a batch drawing restart instruction, and transmits the generated drawing command to the drawing arithmetic device 42 via the communication unit 411. To do.

  Returning to FIG. 1, the drawing operation device 42 is configured by an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or the like, and is displayed by the display device 3 according to the drawing command from the central processing device 41. Perform batch drawing of screens and individual drawing of characters.

  Functionally, the image calculation device 42 includes a drawing execution unit as shown in FIG. The drawing execution unit includes a batch drawing execution unit 4200 and an individual drawing execution unit 4201. When the batch drawing execution unit 4200 receives a drawing command indicating a batch drawing instruction from the central processing unit 41, the screen configuration table 402 corresponding to the display screen to be updated, which is stored in the storage device 40 (see FIG. 3). The execution of batch drawing is started in which each element information is sequentially read out and drawn.

  When the read element information indicates interruption information, the collective drawing execution unit 4200 interrupts execution of the collective drawing and outputs an interruption signal to the central processing unit 41. Whether or not the read element information indicates interruption information indicates whether or not a predetermined value (for example, 0xFFFFFFFF) is stored in the screen area information (4 bytes) of element candidate 1 in the element information. It is determined by.

  When receiving a drawing command indicating a batch drawing restart instruction from the central processing unit 41, the batch drawing execution unit 4200 restarts the interrupted batch drawing.

  The batch drawing execution unit 4200 outputs an inquiry signal to the central processing unit 41 when the read element information includes a plurality of element candidates. When receiving the response data from the central processing unit 41 with respect to the inquiry signal, the collective drawing execution unit 4200 selects an element candidate No. included in the received response data from among a plurality of element candidates. Select the one corresponding to. Then, the collective drawing execution unit 4200 draws an element image based on the selected element candidate.

  When receiving the drawing command indicating the individual drawing instruction from the central processing unit 41, the individual drawing execution unit 4201 reads the font data from the storage device 40 based on the storage destination of the font data stored in the received drawing command. The individual drawing execution unit 4201 then draws characters based on the read font data and the drawing start position stored in the received drawing command.

  FIG. 14 is a flowchart illustrating a procedure of processing (drawing processing) executed by the drawing arithmetic device 42. This drawing process is repeatedly executed at a predetermined cycle.

  When the data from the central processing unit 41 is not received (step S301; NO), the drawing arithmetic unit 42 ends the drawing process in this cycle. On the other hand, when a drawing command or response data related to batch drawing is received from the central processing unit 41 (step S302; YES), the batch drawing execution unit 4200 executes batch drawing processing (step S303). Thereafter, the drawing arithmetic unit 42 ends the drawing process in this cycle.

  If NO in step S302, that is, if a drawing command related to individual drawing is received from the central processing unit 41, the individual drawing execution unit 4201 draws the character specified by the drawing command (step S304). Thereafter, the drawing arithmetic unit 42 ends the drawing execution process in this cycle.

  FIG. 15 is a flowchart showing a procedure of batch drawing processing. When the data from the central processing unit 41 is a drawing command indicating a batch drawing start instruction (step S401; YES), the batch drawing execution unit 4200 uses the drawing command to display a screen configuration table corresponding to the display screen to be drawn. The storage location (memory address) of 402 is extracted, and the extracted memory address is stored in a first address register (not shown) as a read start address (step S402). The first address register is a register for storing a memory address (read start address) at which data reading is started, and is used by the batch drawing execution unit 4200 and the individual drawing execution unit 4201. Then, the batch drawing execution unit 4200 executes batch drawing main processing (step S403).

  When the data from the central processing unit 41 is response data (step S404; YES), the batch drawing execution unit 4200 executes response data reception processing (step S405).

  When the data from the central processing unit 41 is not a drawing command indicating a batch drawing start instruction (step S401; NO) and is not response data (step S404; NO), the data from the central processing unit 41 is batch drawing. Since the drawing command indicates a restart instruction, the batch drawing execution unit 4200 executes batch drawing restart processing (step S406).

  FIG. 16 is a flowchart showing the procedure of the batch drawing main process. The batch drawing execution unit 4200 reads one record of element information from the screen configuration table 402 stored in the storage device 40 (step S501). When the reading is completed, the collective drawing execution unit 4200 updates the reading start address stored in the first address register. That is, the size of element information for one record is added to the read start address.

  When there is no element information, that is, when reading of all element information from the screen configuration table 402 is completed (step S502; NO), the batch drawing execution unit 4200 ends the batch drawing main process.

  When the read element information indicates interruption information (step S503; YES), the batch drawing execution unit 4200 stores the read start address stored in the first address register in the second address register (not shown). (Step S504). The second address register is a register for temporarily saving the reading start address at the time of interruption. Then, the batch drawing execution unit 4200 outputs an interruption signal to the central processing unit 41 (step S505) and ends the batch drawing main process.

  When a plurality of element candidates are included in the read element information (step S506; YES), the batch drawing execution unit 4200 outputs an inquiry signal to the central processing unit 41, and the batch drawing main process is terminated.

  When the read element information does not indicate interruption information (step S503; NO) and there is one element candidate (step S506: NO), the collective drawing execution unit 4200 draws an element image based on this element candidate. This is performed (step S508). That is, the corresponding image data 400 is read from the storage device 40 based on the storage destination of the image data included in the element candidate, and the read image data 400 is drawn according to the drawing area information included in the element candidate.

  FIG. 17 is a flowchart showing the procedure of the response data reception process. The batch drawing execution unit 4200 selects an element candidate No. included in the received response data from among a plurality of element candidates. Is selected (step 601). The collective drawing execution unit 4200 draws an element image based on the selected element candidate (step S602). Then, the batch drawing execution unit 4200 executes a batch drawing main process (step S603). The contents of the batch drawing main process are the same as the contents of the batch main process (see FIG. 16) described above.

  FIG. 18 is a flowchart showing a procedure of batch drawing restart processing. The batch drawing execution unit 4200 stores the memory address stored in the second address register in the first address register (step S701). Thereby, batch drawing can be restarted using the reading start address at the time of interruption. Then, the collective drawing execution unit 4200 executes the collective drawing main process (step S702). The contents of the batch drawing main process are the same as the contents of the batch main process (see FIG. 16) described above.

  As described above, in the remote controller 1 of the present embodiment, when the display screen needs to be updated, the central processing unit 41 instructs the drawing processing unit 42 to perform batch drawing. Upon receiving such an instruction, the drawing calculation device 42 refers to the screen configuration table 402 corresponding to the display screen to be updated and performs batch drawing of the display screen. Thereby, the communication frequency between the central processing unit 41 and the drawing arithmetic unit 42 can be reduced, and the processing load for drawing an image can be reduced.

  In addition, when there is an area in which a character string arbitrarily set by the user can be displayed on the display screen to be updated, the corresponding screen configuration table includes interruption information. Therefore, batch drawing can be interrupted, and character strings set by the user can be drawn individually (individual drawing) for each character. When individual drawing is completed, batch drawing is resumed immediately. Therefore, it is possible to execute drawing of an arbitrary character string set by the user without causing a delay in drawing processing of another image.

  In addition, this invention is not limited to the said embodiment, Of course, the various change in the range which does not deviate from the summary of this invention is possible.

  For example, in the above-described embodiment, there is one area in which a character string arbitrarily set by the user can be displayed on each display screen. However, in each of the plurality of areas, the character strings set by the user can be displayed separately. It may be.

  The remote controller 1 may display not only a character string as a user setting image arbitrarily set by the user but also an icon or other image arbitrarily set (selected) by the user. . Even in this case, the individual drawing instruction unit 4101 of the central processing unit 41 may instruct the drawing arithmetic unit 42 to perform individual drawing of the image when the batch drawing is interrupted. The drawing command at this time stores the storage destination of the image data 400 and the drawing start position in the storage device 40 corresponding to the image.

  In addition, although it is not necessary to switch the display screen, when a partial element image such as the current time needs to be updated, the batch drawing instruction unit 4100 of the central processing unit 41 sends a drawing command to the drawing calculation device 42. In addition, either the element information number corresponding to the element image that does not need to be drawn or the element information number corresponding to the element image that needs to be drawn may be stored. In this way, only the element images that need to be updated can be drawn in the batch drawing performed by the batch drawing execution unit 4200 of the drawing arithmetic unit 42, so that the display screen can be updated at high speed.

  Further, in the above embodiment, when the batch drawing is interrupted, the drawing arithmetic unit 42 temporarily saves the reading start address in the second address register and takes it out when the batch drawing is restarted. The read start address was obtained. However, the present invention is not limited to this, and there are various methods for obtaining the read start address at the time of restart.

  For example, the central processing unit 41 holds in advance a read start address at the time of restart corresponding to the number of batch drawing interruptions for each display screen, and notifies the drawing processing unit 42 when instructing the restart of batch drawing. May be. In this way, it is not necessary to provide an address register for temporarily saving the read start address, and the IC constituting the drawing arithmetic unit 42 can be further downsized.

  Alternatively, information (resume address information) defining a reading start address at the time of restart corresponding to the number of batch drawing interruptions is stored in advance in the storage device 40 for each display screen, and when the batch drawing is restarted, the central processing unit is stored. 41 may notify the drawing arithmetic unit 42 of the storage location of the read start address at the time of resumption. In this way, in the central processing unit 41, as described above, it is possible to save the memory capacity as compared with the configuration in which the reading start address at the time of restart corresponding to the number of batch drawing interruptions is held in advance for each display screen.

  Alternatively, the central processing unit 41 may acquire a reading start address from the drawing arithmetic unit 42 when the batch drawing is interrupted, temporarily store it in the RAM 414, and notify the drawing arithmetic unit 42 when the batch drawing is interrupted. Good. In this manner, the central processing unit 41 can reduce the static memory capacity.

  Also, as shown in FIG. 19, in the screen configuration table 402, information indicating the drawing area of each character when drawing a character string set by the user may be stored in advance as element information indicating interruption information. In the example of FIG. Element information 4-1 to 4-4 indicates interruption information, and each element candidate 1 stores information indicating a drawing area. In such a case, whether or not the interruption information is indicated is determined based on whether or not a predetermined value (for example, 0xFFFFFFFF) is stored in the “storage destination” (4 bytes) of the element candidate 1. The

  In this way, the central processing unit 41 does not need to hold information related to the drawing position of the character string set by the user, so that memory capacity can be saved. Further, since the central processing unit 41 does not need to notify the drawing processing unit 42 of the drawing start position of each character when instructing individual drawing, the processing speed can be increased.

  Various embodiments and modifications can be made to the present invention without departing from the broad spirit and scope of the present invention. Further, the above-described embodiment is for explaining the present invention, and does not limit the scope of the present invention. That is, the scope of the present invention is shown not by the embodiments but by the claims. Various modifications within the scope of the claims and within the scope of the equivalent invention are considered to be within the scope of the present invention.

  The present invention can be suitably employed in a remote controller for operating home appliances, equipment, and the like.
