Description

Display controller and screen pattern information update system

This invention relates to a display operation device and a screen pattern information update system.

The remote controller, that is, the display controller, displays the status of control devices such as home appliances and equipment on a display device such as an LCD (Liquid Crystal Display) or controls user operation information received by an input device such as a touch panel. It is a device that notifies devices. This display operation device includes a nonvolatile memory. This nonvolatile memory holds information related to display contents displayed on the display device (configuration information related to image and screen layout). When the user operates or the state of the control device changes, the display controller reads information on the display content from the nonvolatile memory and updates the display content on the screen.

∙ You may want to change the screen pattern of the display / operator screen after the product is shipped. For example, there is a case where the display language is desired to be changed from Japanese to another display language such as English after the product is shipped. In such a case, it is necessary to replace with another display controller for the screen pattern to be changed (device replacement), or to record screen information of various screen patterns in a large-capacity nonvolatile memory in advance.

Embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1 FIG.
First, a first embodiment of the present invention will be described.

FIG. 1 shows the configuration of the air conditioning system 1 during normal operation. As shown in FIG. 1, the air conditioning system 1 includes an air conditioner 10 and a display operation device 200.

The air conditioner 10 performs air conditioning control based on an operation command transmitted from the display / operator 200. The air conditioner 10 transmits its own state (for example, control state) to the display operation device 200.

The display operation device 200 is, for example, a remote controller. The display operation device 200 receives a user operation. The display operation device 200 transmits an operation command to the air conditioner 10 according to a user operation. Moreover, the display operation device 200 displays the state of the air conditioner 10 transmitted from the air conditioner 10 on the screen.

The display controller 200 can display a screen in any of a plurality of different screen patterns such as a Japanese display screen, an English display screen, and an uppercase font display screen. In this air conditioning system 1, it is possible to switch the screen pattern displayed on the display operation device 200. In this embodiment, a case where an operator who changes the screen pattern displayed on the display operation device 200 switches the screen pattern from Japanese display to English display will be described.

The configuration for switching the screen pattern of the display operation device 200 will be described with reference to FIG. In FIG. 2, an update information communication device 100 connected to the display operation device 200 is added to the air conditioning system 1 in FIG. 1. The update information communication device 100 is used when switching the screen pattern displayed on the display operation device 200. The update information communication device 100 transmits the update information of the screen pattern information to the display operation device 200. The air conditioning system 1 including the update information communication device 100 corresponds to a screen pattern information update system.

The display operation device 200 includes a communication unit 210, an operation control unit 220, a drawing unit 230, a recording unit 240, a display control unit 250, a display unit 260, and an operation input unit 270.

The communication unit 210 is a communication interface for transmitting and receiving various types of information between the display operation device 200 and the update information communication device 100. For example, the communication unit 210 receives update information of screen pattern information from the update information communication device 100.

The operation control unit 220 performs overall control of the display operation device 200. For example, the operation control unit 220 transmits an operation command to the air conditioner 10 according to the operation signal input from the operation input unit 270. Further, the operation control unit 220 selects a screen to be displayed on the display unit 260 according to the operation signal input from the operation input unit 270. Furthermore, the operation control unit 220 instructs the drawing unit 230 to perform screen drawing according to the input operation signal.

In addition, the operation control unit 220 performs rewrite control of the recorded contents (screen pattern information) of the recording unit 240 based on the received update information. Specifically, the operation control unit 220 causes the drawing unit 230 to rewrite the recording content (screen pattern information) of the recording unit 240 according to an instruction from the update information communication device 100. This rewriting process is also called a screen pattern information update process.

The drawing unit 230 performs screen drawing. The drawing unit 230 switches its internal operation according to the port control signal received from the operation control unit 220. Port control signals include port control signals A and B.

As shown in FIG. 3, when the operation control unit 220 displays a screen on the display unit 260, the operation control unit 220 outputs a port control signal A as a first port control signal and a drawing instruction to the drawing unit 230. When the port control signal A and the drawing instruction are input, the drawing unit 230 reads information (screen pattern information 400) necessary for screen drawing processing from the recording unit 240, and displays the display data according to the read screen pattern information 400. The image is output to 250 and the screen is displayed on the display unit 260. The screen pattern information 400 includes a screen configuration information table 420 and an image data group 440 corresponding to the screen instructed by the operation control unit 220. The screen configuration information table 420 is a table in which information indicating a screen configuration using the image data group 440 is registered. This series of processing is referred to as screen drawing processing.

On the other hand, as illustrated in FIG. 4, when the operation control unit 220 rewrites the screen pattern information 400 recorded in the recording unit 240, the operation control unit 220 outputs a port control signal B as a second port control signal to the drawing unit 230. Output to. When the port control signal B is input, the drawing unit 230 rewrites the screen pattern information 400 recorded in the recording unit 240 with the update information received by the communication unit 210 and input from the operation control unit 220.

As described above, the drawing unit 230 causes the display unit 260 to display a screen according to the screen pattern information 400 recorded in the recording unit 240, and based on the update information of the screen pattern information 400 received by the communication unit 210, the recording unit The screen pattern information 400 recorded in 240 is rewritten.

When rewriting the screen pattern information 400, if the screen is being displayed on the display unit 260, the operation control unit 220 rewrites the screen pattern information 400 after the screen display is completed. To control.

Details of the operation of the drawing unit 230 will be described later.

The screen configuration information table 420 records screen configuration information for each screen. In FIG. 7, screen configuration information of

screen numbers

0, 1, 2,... Is shown as screen configuration information for each screen.

Furthermore, in the screen configuration information table 420, a screen number for identifying the screen, the number of images constituting the screen, an image number for each image constituting the screen, and drawing coordinates corresponding to the image number are registered. In FIG. 7, screen configuration number 0 includes image number 1 and its drawing coordinates (x1, y1), and image number 3 and its drawing coordinates (x3, y3).

In the image attribute table 430, an image number, an image size, and an image address are registered in association with each other. In FIG. 7, the image sizes ((100, 100), (200, 100), (100, 200)) corresponding to the

image numbers

1, 2, and 3 and the image addresses (a, b, c) are shown. ing. The image address is an address indicating a storage location of image data corresponding to the image number in the recording unit 240.

The image data group 440 includes image data in which the display color of each image is stored in a predetermined format, for example, BMP (bitmap). FIG. 7 shows that image data 1 is stored at address a, image data 2 is stored at address b, and image data 3 is stored at address c.

Returning to the explanation of FIG. The update information communication device 100 includes a communication unit 110, an update unit 120, an update flag table creation unit 130, a full screen information recording unit 140, a screen pattern selection unit 150, and an update flag table 160.

The communication unit 110 is a communication interface that is connected to the communication unit 210 included in the display operation device 200 wirelessly or by wire. The communication unit 110 transmits and receives various types of information between the display operation device 200 and the update information communication device 100.

FIG. 8 schematically shows the communication unit 210 of the display operation device 200 and the communication unit 110 of the update information communication device 100. As illustrated in FIG. 8, the communication unit 210 includes a communication coil 211 and a serial I / F 212. On the other hand, the communication unit 110 includes a communication coil 111 and a serial I / F 112. Communication between the display operation device 200 and the update information communication device 100 is performed by contactless communication using electromagnetic induction between the communication coil 211 and the communication coil 111.

The update unit 120 creates update information based on the update flag table 160 created by the update flag table creation unit 130. The update unit 120 transmits the created update information to the display operation device 200 via the communication unit 110.

The update flag table creation unit 130 compares the screen pattern information in the current screen pattern displayed by the display operator 200 with the screen pattern information in the updated screen pattern selected by the operator in the screen pattern selection unit 150. . The update flag table creation unit 130 creates the update flag table 160 based on the comparison result.

The full screen information recording unit 140 stores screen pattern information corresponding to all screen patterns.

The screen pattern selection unit 150 accepts operator input. The screen pattern selection unit 150 outputs the updated screen pattern label selected by the operator through the operation input to the update flag table creation unit 130.

The structure of the update flag table 160 is shown in FIG. As shown in FIG. 9, in the update flag table 160, an image number corresponding to each image, a screen number list, and an image data update flag are registered in association with each other.

The image number is a number assigned to each image. The screen number list stores one or more screen numbers of screens in which the predetermined image is one of the constituent images. The image data update flag is a flag indicating whether or not the recording unit 240 needs to be updated for each image.

In the above configuration, it is desirable to configure the operation control unit 220 from a microcomputer. Further, it is desirable that the drawing unit 230 is constituted by a drawing-dedicated IC that performs screen drawing processing. It is desirable that the recording unit 240 is a serial ROM (Read Only Memory), the display control unit 250 is an LCD controller, and the display unit 260 is an LCD. The display unit 260 is desirably disposed integrally with the operation control unit 220 (same housing), but may be disposed separately. Furthermore, it is desirable that the operation input unit 270 is a contact switch. However, it is not limited to these.

The communication unit 210 may be a communication interface that communicates wirelessly, such as infrared or WiFi (Wireless Fidelity). The communication unit 210 may be a communication interface connected to the communication unit 110 via a wire. Examples of such communication interfaces include RS-232C or Ethernet (registered trademark).

Further, as the display control unit 250, other display controllers such as a VFD (fluorescent display tube) controller, an organic EL controller, and an electronic paper controller may be used. Further, as the display unit 260, other display devices such as a VFD, an organic EL (Electro-Luminescence) display, and electronic paper may be used. Furthermore, as the operation input unit 270, other input switches such as a charging switch, a photoelectric switch, and a piezoelectric element switch may be used.

Next, the screen drawing operation will be described.

FIG. 10 shows the screen drawing operation of the drawing unit 230.

As shown in FIG. 10, the drawing unit 230 first waits until it receives the port control signal A (step S10; No). When the port control signal A is received (step S10; Yes), the drawing unit 230 waits until the drawing start flag 310 is set (step S11; No). When a drawing instruction is output from the operation control unit 220 and the drawing start flag is set (step S11; Yes), the drawing unit 230 performs screen drawing of the screen number set in the screen number register 320 as follows. Perform the action.

First, the drawing unit 230 reads the screen number from the screen number register 320 (step S12). The screen currently displayed on the display unit 260 can be identified by the read screen number.

Subsequently, the drawing unit 230 reads the screen configuration information table 420 corresponding to the screen number from the recording unit 240 and writes the number n of screen configuration images included in the screen configuration information table 420 in the image counter 330 (step S13). .

Subsequently, the drawing unit 230 performs a drawing process (step S14). Specifically, the drawing unit 230 reads image information (image number, drawing coordinates) for one image included in the image configuration information from the recording unit 240 and sets the drawing coordinates in the drawing coordinate register 370. Then, the drawing unit 230 specifies an image size and an image address corresponding to the image number from the image attribute table 430 and sets them in the image size register 350 and the image address register 360. Further, the drawing unit 230 reads the image data stored at the image address from the image data group 440 of the recording unit 240, and writes the display data to the VRAM area determined by the drawing coordinates and the image size.

Subsequently, the drawing unit 230 subtracts 1 from the value n stored in the image counter 330 and stores it again in the image counter 330 (step S15).

Subsequently, the drawing unit 230 determines whether n> 0 is satisfied (step S16). If the value (n) of the image counter 330 is 1 or more (step S16; Yes), the drawing unit 230 performs a drawing process on the next image included in the screen configuration information (step S14).

Thereafter, steps S14 → S15 → S16 are repeated until n> 0. When the value n of the image counter 330 becomes 0 or less (step S16; No), the drawing unit 230 clears the drawing start flag 310 (step S17) and ends the screen drawing process.

(Screen pattern information update process)
Next, a screen pattern information update process in which the update information communication device 100 is connected to the display operation device 200 and the screen pattern information stored in the recording unit 240 is rewritten with another screen pattern information will be described.

FIG. 11 is a flowchart showing screen pattern information update processing of the update information communication device 100 when the screen pattern information 400 is updated.

As shown in FIG. 11, first, the screen pattern selection unit 150 selects the update screen pattern information 400 by outputting the screen pattern label 410 selected by the operator to the update flag table creation unit 130 (step S20). ).

Subsequently, the update flag table creation unit 130 executes a subroutine for creating the update flag table 160 by comparing the contents of the screen pattern information before and after the update (step S21).

Subsequently, based on the update flag table 160, the update unit 120 transmits update image data (only image data that needs to be rewritten) to the display operation device 200, and a subroutine (update image data) that instructs rewriting of the recording unit 240. (Transmission and rewrite instruction) are executed (step S22).

FIG. 12 shows a subroutine in which the update flag table creation unit 130 in step S21 in FIG. 11 creates an update flag table.

As shown in FIG. 12, first, the update flag table creation unit 130 acquires the current screen pattern label from the display controller 200 (step S30).

Subsequently, the update flag table creation unit 130 substitutes 1 for the variable i (step S31).

The update flag table creation unit 130 reads, from the full screen information recording unit 140, the screen pattern information 400 for which the operator has designated updating and the current screen pattern information 400, and the image data corresponding to each image number i is read. It is determined whether or not they match (step S32).

The update flag table creation unit 130 turns on the image data update flag corresponding to the image number i in the update flag table 160 only when the image data is different (Step S32; No) (Step S33). That is, when the image data matches (step S32; Yes), the image data update flag corresponding to the image data remains off.

Subsequently, the update flag table creation unit 130 increments the variable i by 1 (step S34).

Subsequently, the update flag table creation unit 130 determines whether or not comparison of image data corresponding to all image numbers has been completed (step S35). If not completed (step S35; No), the update flag table creation unit 130 repeats steps S32 → S33 → S34 → S35.

When the comparison of the image data corresponding to all the image numbers has been completed (step S35; Yes), the update flag table creation unit 130 ends the update flag table creation process.

FIG. 13 shows a subroutine for transmitting update image data and instructing rewriting of screen pattern information in step S22 in FIG.

As illustrated in FIG. 13, the update unit 120 first transmits the screen pattern label selected by the worker received by the screen pattern selection unit 150 to the display operation device 200 via the communication unit 110, and the screen pattern label is displayed. 410 is updated (step S40).

Subsequently, the update unit 120 substitutes 1 for the variable i (step S41).

Subsequently, the update unit 120 reads the update flag table 160 and acquires the screen number k corresponding to the image number i from the screen number list (step S42). The acquired screen number is stored in the built-in ROM of the update unit 120.

Subsequently, the update unit 120 reads the update flag table 160 and determines whether or not the image data update flag corresponding to the image number i is on (step S43).

If the image data update flag of image number i is on (step S43; Yes), the update unit 120 sends the write destination address to the recording unit 240, the image size, and the updated image data via the communication unit 110. Is transmitted to the display controller 200 (step S44).

Subsequently, the update unit 120 determines whether or not the screen with the screen number k is being drawn (step S45). If drawing is in progress (step S45; Yes), the process waits until screen drawing is completed.

When the drawing of the screen with the screen number i is completed from the display operation device 200 (step S45; No), the update unit 120 stores the image stored in the full-screen information recording unit 140 in the display operation device 200 via the communication unit 110. A rewrite instruction command for updating the data group 440 is transmitted (step S46).

Subsequently, the update unit 120 increments the variable i by 1 (step S47).

Subsequently, the update unit 120 transmits to the display controller 200 all the image data corresponding to the image number i for which the image data update flag of the update flag table 160 is turned on, and determines whether or not the update is completed. (Step S48). If the update has not been completed (step S48; No), the update unit 120 repeats steps S42 to S48.

If the update has been completed (step S48; Yes), the update unit 120 turns off all the image data update flags and transmits an update completion command to the display operation device 200 (step S49). The drawing unit 230 that has received this command redraws the screen of the current screen number in accordance with the updated screen pattern information 400 after the rewriting of the screen pattern information 400, and displays a screen based on the updated screen pattern information 400. It is displayed on the display unit 260.

FIG. 14 shows an example of updating the screen pattern information 400 using the update flag table 160. First, in step S20 of FIG. 11, the screen pattern label 410 is updated from [Japane] to [English]. Next, based on the update flag table 160, update information is transmitted and updated. FIG. 14 shows how image data 1 is updated to image data 1 '.

15A to 15C show the configuration of the screen pattern information 400 recorded in the updated recording unit 240. FIG. 15A to FIG. 15C show examples of screens displayed on the display unit 260 before and after the screen pattern information 400 is updated.

FIG. 15A shows a display screen 500 of screen number 0 before update. As shown in FIG. 15B, the display screen 500 includes two

images

510 and 520.

As shown in FIG. 15B, the image 510 is an image with an image number 1, and the image 520 is an image with an image number 3. By updating the screen pattern information 400 of the recording unit 240, the image 510 is updated to the image 511, but the image 520 is not updated. As a result, the display screen with the screen number 0 after the update becomes a display screen 501 shown in FIG. 15C.

In this embodiment, the full screen information recording unit 140 is provided inside the update information communication device 100. However, a network connection function may be added to the update information communication device 100 and the full screen information recording unit 140 may be provided outside the update information communication device 100 such as a server. Thus, when new screen pattern information 400 is created, the new screen pattern information 400 is displayed on the display controller 200 via the network without updating the contents of the full screen information recording unit 140 inside the update information communication device 100 one by one. Can be written on.

In this embodiment, the drawing unit 230 is provided as a drawing-dedicated IC having a drawing processing function different from the microcomputer of the operation control unit 220. This is because when the remote control communication control and the drawing operation are executed by one microcomputer, the data transfer amount of the drawing operation is large, so that the processing load of the microcomputer is increased, and a highly functional microcomputer is required. However, the processing load on the microcomputer can be reduced by separately executing the two functions of remote control communication control and drawing operation by the microcomputer and the drawing-dedicated IC. As a result, it is possible to perform remote control communication control without delay even with a low-performance microcomputer.

In this embodiment, communication between the communication unit 210 provided in the display operation device 200 and the communication unit 110 provided in the update information communication device 100 is performed by non-contact communication. As a result, it is not necessary to connect the display operation device 200 and the update information communication device 100 by wire, and the screen pattern information 400 can be updated simply by overlaying the update information communication device 100 on the display operation device 200. The update operation can be easily performed in a short time.

In this embodiment, a microcomputer is used as the operation control unit 220, and a drawing-dedicated IC is used as the drawing unit 230. In this case, the drawing unit 230 performs drawing processing according to a drawing instruction from the operation control unit 220. For this reason, an interface between the operation control unit 220 and the drawing unit 230 is required. In order to perform high-speed drawing, the drawing unit 230 needs to be directly connected to the recording unit 240 without passing through other components such as the operation control unit 220. For this reason, an interface between the drawing unit 230 and the recording unit 240 is required.

If the update information is to be directly rewritten from the operation control unit 220 to the recording unit 240, an interface between the operation control unit 220 and the recording unit 240 is newly required. In this case, as shown in FIG. 16, a changeover switch 290 between the operation control unit 220 and the drawing unit 230 is required. The changeover switch 290 has a function of switching the connection destination of the recording unit 240 from the operation control unit 220 to the drawing unit 230 in accordance with a switching control signal received from the operation control unit 220. When such a changeover switch 290 is not provided, a dual access system of the recording unit 240 is required so that the operation control unit 220 and the drawing unit 230 can be connected to the recording unit 240 at the same time. In this case, the cost of the recording unit 240 is increased.

The display operation device 200 according to this embodiment switches the internal operation of the drawing unit 230 by a port control signal received from the operation control unit 220 without providing the changeover switch 290 or the dual access system. In this way, image drawing and screen information updating can be performed at low cost.

In this embodiment, when updating the information recorded in the recording unit 240, only necessary image data is updated based on the update flag table 160, and the screen configuration information table 420 and the image attribute table 430 are rewritten. Not done. As a result, the update time can be shortened compared to updating all the screen pattern information 400.

In step S44 in FIG. 13, the screen configuration information table 420 and the image attribute table 430 may be transmitted for rewriting.

In this embodiment, after the update of the screen pattern information 400 is completed, the screen currently displayed on the display controller 200 is redrawn using the updated screen pattern information (step S49 in FIG. 13). Thereby, the user can confirm the update of the screen pattern without performing a special operation.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described.

In the first embodiment, the internal operation of the drawing unit 230 (drawing-dedicated IC) is switched by the port control signal received from the operation control unit 220. The first embodiment is different from the first embodiment in that an operation state output unit 780 is provided in the display operation device 700.

FIG. 17 shows the configuration of the air conditioning system 1 according to the second embodiment. As shown in FIG. 17, the air conditioning system 1 includes an update information communication device 600, a display operation device 700, and an air conditioner 10.

The display operation device 700 differs from the display operation device 200 according to the first embodiment in that the display operation device 700 includes an operation control unit 720 instead of the operation control unit 220, and further includes an operation state output unit 780.

Based on the operation signal received from the operation input unit 270, the operation control unit 720 selects an operation command to the air conditioner 10 or a remote control such as selecting a screen to be displayed on the display unit 260 and instructing the drawing unit 230 to perform screen drawing. Do. Further, the operation control unit 720 performs screen pattern information update processing for rewriting the contents of the recording unit 240 via the drawing unit 230 according to an instruction from the update information communication device 600. Further, the operation control unit 720 controls update processing of the screen pattern information 400 based on the operation signal output from the operation state output unit 780.

The operation state output unit 780 outputs an update off signal to the operation control unit 720 when the drawing unit 230 starts reading the screen pattern information 400 from the recording unit 240 (when drawing is started). On the other hand, the operation state output unit 780 outputs an update on signal to the operation control unit 720 when reading is completed.

18 and 19 show the operation of the operation state output unit 780.

As illustrated in FIG. 18, when the drawing unit 230 starts reading information (screen pattern information 400) necessary for screen drawing processing from the recording unit 240, the operation state output unit 780 sends an update off signal to the operation control unit 720. Output. When the update off signal is input, the operation control unit 720 prohibits the drawing unit 230 from rewriting the recording unit 240.

As shown in FIG. 19, when the drawing unit 230 finishes reading the screen pattern information 400 from the recording unit 240, the operation state output unit 780 outputs an update on signal to the operation control unit 720. When the update on signal is input, the operation control unit 720 permits the drawing unit 230 to rewrite the recording unit 240.

The operation control unit 720 is provided with a reception buffer. In the reception buffer, update information of the screen pattern information 400 transmitted from the update information communication device 600 and received by the communication unit 210 is temporarily stored.

The operation control unit 720 rewrites the recording unit 240 via the drawing unit 230 based on the update information extracted from the reception buffer. The operation control unit 720 transmits an update prohibition signal for prohibiting update by update information to the update information communication device 600 via the communication unit 210 when the empty size of the reception buffer becomes a predetermined size or less. Thereafter, when the rewriting process of the information stored in the reception buffer to the recording unit 240 is completed, the operation control unit 720 transmits an update permission signal to the update information communication device 600 via the communication unit 210.

The update information communication device 600 is different from the update information communication device 100 according to the first embodiment in that an update unit 620 is provided instead of the update unit 120.

The update unit 620 transmits update information created based on the update flag table 160 created by the update flag table creation unit 130 to the display operation device 700 via the communication unit 210. In addition, when the update unit 620 receives an update prohibition signal from the display operation device 700, the update unit 620 temporarily stops transmission of update information from the update information communication device 600 to the display operation device 700. When receiving the update permission signal from the display operation device 700, the update unit 620 resumes transmission of update information.

FIG. 20 shows a screen pattern information update process of the update information communication device 600.

As shown in FIG. 20, steps S20 and S21 are the same as those in the first embodiment.

After execution of step S21, the updating unit 620 executes a subroutine for transmitting updated image data that transmits only the image data that needs to be rewritten to the display operation device 200 based on the generated update flag table 160 (step S52). .

FIG. 21 shows a subroutine of step S22 in FIG. 20, that is, a subroutine for transmitting update image data by the update unit 620.

As shown in FIG. 21, the screen pattern update process according to this embodiment differs from the screen pattern update process according to the first embodiment in that step S62 is executed instead of step S42. In step S <b> 62, the update unit 620 transmits the screen number k of the image number i to the display operation device 200.

Also, the screen pattern update process according to this embodiment differs from the screen pattern update process according to the first embodiment in that steps S45 and S46 are not executed.

Next, the operation of the display operation device 700 corresponding to the screen pattern update process will be described.

21. When the screen pattern label transmitted in step S40 of FIG. 21 is received from the update information communication device 600, the operation control unit 720 rewrites the screen pattern label 410 to the screen pattern label selected by the operator.

Next, the operation control unit 720 rewrites the image data based on the received update information. At this time, the operation control unit 720 pauses rewriting during drawing of the screen corresponding to the screen number k received in step S62. For example, when the update is performed using the update flag table 160 in FIG. 9, the operation control unit 720 pauses the rewriting of the image data of the

image numbers

1 and 3 while the screen of the screen number 0 is being drawn.

In addition, when an update off signal is input from the operation state output unit 780, the operation control unit 720 temporarily stops rewriting. On the other hand, when an update on signal is input from the operation state output unit 780, the operation control unit 720 resumes rewriting.

Furthermore, when the update information received from the update information communication device 600 reaches the set reception buffer size, the operation control unit 720 transmits an update prohibition signal to the update information communication device 600. Thereafter, when the rewriting process of the information stored in the reception buffer is completed, the operation control unit 720 transmits an update permission signal to the update information communication device 600. Thereafter, when receiving the update completion command, the operation control unit 720 sets the drawing start flag 310 to the drawing start, and redraws the screen having the currently displayed screen number.

In this embodiment, by providing the operation state output unit 780, the screen pattern information 400 stored in the recording unit 240 can be updated even when the screen is being updated. In addition, since the timing of rewriting the recording unit 240 is controlled on the display operation device 700 side, the update procedure of the update information communication device 600 can be simplified.

In this embodiment, the display operation unit 700 transmits an update prohibition signal to the update information communication unit 600 when the empty size of the reception buffer of the display operation unit 700 is equal to or smaller than a predetermined size. The update information communication device 600 that has received the update prohibition signal temporarily stops transmission of update information until an update permission signal is received from the display operation device 700. As a result, the reception buffer size required by the display operation device 700 can be reduced, and the memory used by the operation control unit 720 can be reduced.

In the above embodiment, the program to be executed is a computer-readable recording such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), and an MO (Magneto-Optical Disk). A system that executes the above-described processing may be configured by storing and distributing the program on a medium and installing the program.

Further, the program may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded, for example, superimposed on a carrier wave.

Further, when the above functions are realized by sharing an OS (Operating System), or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. You may also download it.
