It is performed under the control of the CPU of the PC.

Next, the operation of this basic example will be described. <Operation Description 1> First, referring to FIG. 5, a case is shown in which the screen of the display operation unit 6 provided in the main control device A is displayed and operated from a remote monitoring / display device B ... or a remote MMI device such as a personal computer PC. An example in which data access is performed in window units when the display is switched from an arbitrary screen to another screen will be described.

Now, when communication is started between the main control unit A and the remote MMI device (the sub-monitoring display unit B or the personal computer PC, the same applies hereinafter), when the communication having the format shown in FIG. Initial setting data is transmitted from the remote MMI device to main controller A. On the other hand, in main controller A,
Various conditions for the remote MMI device from the start of communication to the disconnection of the line are set based on the received data. Here, the initial setting data at the start of communication includes a download condition described below and a window object change transmission execution parameter. In this case, the download condition is set to “none”. Download of initial screen data at the time of starting communication from the control device A to the remote MMI device is executed. The case where the download condition is set to “present” will be described later.

If the window object change transmission execution parameter is set to "window change: execution, object change: execution", the properties of the window object data of main controller A after the initial screen data is downloaded. Every time a change occurs (for example, when any object is selected in a window in which a plurality of objects are displayed), change display event data for the entire window or for each object is transmitted from main controller A to remote MMI. Sent to the device. On the other hand, if the change transmission execution parameter is set to “window change: executed, object changed: not executed”, the property change of the window of the main control device A after the download of the initial screen data, as well as some object data Even when only a property change occurs, the change display event data is transmitted to the remote MMI device each time as a change in the entire window.

Here, the download communication data of the initial screen data has a data structure having window parameters as shown in FIG. 7 and parameters of all objects contained in the window, and the number of objects contained in the window. The data length differs depending on the type. The window change display event communication data transmitted from the main control device A is transmitted to the sub monitoring display device B and the personal computer PC in the processing B7, C7 shown in FIGS.
Processing B via (modem communication interface processing unit)

Sent to In these processes B1 and C1, each window
Processing B and C2 (window / object reproduction / drawing processing unit) using window or object reproduction / drawing processing from display data for each object
3, drawing parameters to be passed to C3 (screen output processing unit) are generated, and sent to the sub-display operation unit 16 and the display device 23 from processes B3 and C3 to display windows and objects. As a result, as shown in steps 1 and 2 of FIG. 5, the same window and object screen are displayed on the display operation unit 6 of the main control device A, the sub display operation unit 16 of the remote MMI device, and the display device 23. Is done.

Next, the sub display operation unit 1 of the remote MMI device
6 and _one of a plurality of objects O ₁ and O ₂ in the window W ₁ displayed on the screen of the display device 23 are selected by the user with the mouse 22 or the like (step 3), as shown in FIGS. 3 and 4. Through processes B4 and C4 (touch panel interface processing unit)
6 (object press event data generation processing unit for remote MMI device). Then, object press event communication data as shown in FIG. 8 is generated in processes B6 and C6, and one of the objects O ₁ and O ₂ on the screen is selected by the main controller A via processes B7 and C7. Event is sent.

In the main control unit A, the received object press event data is processed through a process A8 (modem communication interface processing unit) shown in FIG.
The processing is sent to the object pressing event data analysis processing unit from the MI device), and the display operation unit 6 of the main control device A is processed in process A6.
The same object O ₁ as displayed on, O ₂ depresses the processing A4 processed through the (touch panel interface processing unit) A1 (screen operation system main control processing unit) in the same and object pressing event data to be sent Event data is generated and sent to process A1. In process A1, the same screen control process as when the screen of the display operation unit 6 of the main control device A is operated is performed.

Here, steps 4 to 5 in FIG.
When a process of displaying another page is performed as shown in (1), a new screen drawing command is sent in process A5 (screen operation sub-control processing unit) shown in FIG. Work memory in which window object data being displayed in section 6 is stored (variable data storage section 4)
To return the load to the process A1 the specified screen data from the table Ta ₁ (drawing window object data storage section of the screen). In process A1, the screen data newly loaded in the variable data storage unit 4 is expanded into individual window data and object data, and the process A2 is executed.
(Drawing processing instruction) to (screen object drawing processing unit). Based on this drawing processing command, processing A2 is processing A
Another page (window W ₂ and object O ₁ ...) Is displayed on the display operation unit 6 of the main control device A via 3 (LCD screen output processing unit). Here, if the main controller A is communicating with the remote MMI device, the process A1 performs a window projection of a new screen to the remote MMI device according to the contents of the initial setting data received from the remote MMI device at the start of communication. The data is transmitted to the remote MMI device via processing A7 (window object drawing event data generation processing unit for remote MMI device) and processing A8 (modem communication interface processing unit) and A9 (sub-operation communication interface processing unit). . As a result, step 5
And as shown in step 6, the display operation unit 6 of the main control device A and the sub-display operation unit 16 of the remote MMI device according to the object selection operation performed on the remote MMI device side.
And the screen display of the display device 23 is switched. Hereinafter, the same processing is repeated until the line is disconnected. <Operation Description 2> Next, referring to FIG. 9, an example in which data access is performed in units of objects in which numerical values are input using numeric keys displayed on the screen will be described.

The processing up to step 2 in FIG.
Since the processing is the same as that up to step 2 in, the description is omitted. Here, when the user selects one of a plurality of objects O ₁ ... Displayed on the screen of the sub display operation unit 16 of the remote MMI device or the display device 23 with the mouse 22 or the like (step 3), FIG. And processing B6, C6 via processing B4, C4 (touch panel interface processing unit) shown in FIG.
Generates object press event communication data shown in FIG. 8, and transmits an event indicating that an object on the screen has been selected to main controller A via processes B7 and C7.

In the main controller A, the object press event sent from the remote MMI device is processed in the processing A8 shown in FIG.
Process A6 via (modem communication interface processing unit)
(Object pressing event data analysis processing unit from remote MMI device), process A6 is pressed by the object on display operation unit 6 of main control device A, and process A4 (touch panel interface processing unit) shown in FIG. Event data similar to the object press event sent to the process A1 (screen operation system main control processing unit) via the interface is generated and sent to the process A1. The process A1 performs the same screen control process as when the screen of the display operation unit 6 of the main control device A is operated.

The change Here, as shown in Step 4 of FIG. 9, the numeric input key setting value display 50 numbers from 0 on the object O ₂ (10-key) to change the object O ₁ ... figures selected An example in which a display process is performed is described. In this case, the processing A1 changes the display character property of the set value display object of the numeric input key which already exists on the work memory (variable data storage unit 4) for storing the window object data being displayed,
A drawing processing command for only the designated object is issued to the process A2 (screen object drawing processing unit), and the process A2 displays the screen of the display operation unit 5 of the main control device A via the process A3 (LCD screen output processing unit). Update display. At this time, if the main controller A is communicating with the remote MMI device, the process A1 is performed as shown in FIG. 10 for the remote MMI device according to the contents of the initial setting data received from the remote MMI device at the start of communication. Such a change display event of the target object data is transmitted via the processing A7 and the processing A8.
As a result, as shown in steps 6 to 8, the remote M
The display operation unit 6 of the main control device A, the sub display operation unit 16 of the remote MMI device, and the screen display (only object display) of the display device 23 are switched in accordance with the object selection operation performed on the MI device side. become. Hereinafter, the same processing is repeated until the line is disconnected.
However, if the change transmission execution parameter of the window object is “window change: executed, object change: not executed”, change display event data shown in FIG. 7 is transmitted as a change in the entire window in which the target object exists.

As described above, according to the first basic example , the remote MMI device (the sub-monitoring display device B or the personal computer PC) has programs for the screen display reproduction process and the screen control process for the number of screens of the main control device A. Instead, the screen display control can be executed on the remote MMI device with the same display content and operability as displayed on the display operation unit 6 of the main control device A. Further, in response to a change of an existing screen or the addition of a new screen in the display operation unit 6 of the main control device A, the data of the change and the new screen are transmitted from the main control device A to each remote M.
Since the information is transmitted to the MI device, display and operation can be performed without changing the program on the remote MMI device side. Further, all the screens of the main controller A can be displayed and operated on each remote MMI device without requiring a common or unique screen control program for each screen at the time of screen operation.

( Basic Example 2) Since the system configuration of this basic example is common to that of basic example 1,
Common parts are denoted by the same reference numerals, and illustration and description are omitted. In this basic example , each process of the window / object reproduction / display means and the key input judging means provided in the remote MMI device in the above basic example 1 (FIG. 3)
And having no processes B2 and C2 (window / object reproduction / drawing processing unit) in the software module configuration diagram of FIG. 4 and downloading a necessary executable program file from the main controller A to the remote MMI device at the start of communication, The feature is that the program file is expanded.

FIG. 11 shows an example of performing data access in units of windows when switching the display of the display / operation unit 6 provided in the main controller A from an arbitrary screen to another screen, and FIG. An example is shown in which data access is performed on an object basis by inputting a numerical value using the numeric keypad displayed above. Now, when communication is started between the main control device A and the remote MMI device (the sub monitoring display device B or the personal computer PC, the same applies hereinafter), the format as shown in FIG. The initial setting data at the start of communication is transmitted from the remote MMI device to the main control device A, and the main control device A performs various conditions for the remote MMI device from the start of communication to the disconnection of the line based on the received data. Set.

[0026] In this basic example where downloading condition of the initial setting data at the start of communication is set to "Yes", recorded in the table Ta ₂ processing A1 of the main control unit A shown in FIG. 2 manages All the object display program codes that can be displayed on the screen of the display operation unit 6 of the main control device A are used to download the initial screen data of the display data displayed on the screen of the display operation unit 6 of the main control device A. Previously, it is downloaded to the remote MMI device via process A7 and process A8. Then, the downloaded object display program code is developed on the processes B2 and C2 (window object reproduction / drawing processing unit) by the processing B8 and C8 (reproduction / drawing processing code download processing unit) of each remote MMI device. Then, the same process as that of the first embodiment can be executed.

As described above, according to this basic example , the remote MM
When accessing the main control unit A from the I device (the sub-monitoring display unit B and the personal computer PC), a program file for realizing the window object reproduction display function and the key input determination function is downloaded from the main control unit A to the remote MMI device. Thus, the display operation unit 6 of the main control device A can be changed without changing the processing program of the remote MMI device in response to a change in the type or version of the window or object displayed on the display operation unit 6 of the main control device A. Remote MMI with the same display content and operability as displayed on
The screen display control can be executed on the device. Further, there is an advantage that it is not necessary to change or add a program of the remote MMI apparatus to change and update the window / object reproduction / display function for reproducing / displaying the window or object data and the key input determination function.

[0028] (Embodiment type condition) In the present embodiment, in the configuration of the first basic example or basic example 2, depending on the amount of communication data object change display event data transmitted and received between the main controller A and the remote MMI device Thus, the object change processing is performed more efficiently.

As shown in the example of FIG. 12 in the basic example 2, the notification of the object change display event data to the remote MMI device due to the occurrence of the event of the main control device A after the start of the communication is performed within a specific time (for example, 1 In the case of a screen operation in which only one to several screens occur within a second), the amount of communication data between the main control device A and the remote MMI device is extremely small, so the rendering reflection time on the remote MMI device is a problem. Not done. However, for example, on a screen displaying the state of the facility loads 10 monitored by the main controller A by the color change of the graphic object (for example, on in red, off in green), the facility loads 10 are shown on one window. When several tens of objects are displayed, the equipment load 10... Simultaneously changes, and a change display event process occurs on the object on the screen. These are all object change display events, and the data shown in FIG. 10 is simultaneously transmitted to the remote MMI device, so that the main control device A and the remote MMI device C for the present processing temporarily.
The PU operation rate increases, and the display response efficiency deteriorates.

FIGS. 13 (a) and 13 (b) correspond to FIGS.
0 shows the data format of the change display event communication data at the time of the window change and the data format of the change display event communication data at the time of the object change. As the number of the object change display events occurring within a certain specific time increases,
In the case of the object change shown in FIG.
The total number of communication bytes increases by the M-byte header and the N-byte window management number.

Therefore, in the present embodiment, when an object change display event occurs within one window within a certain period of time, the process A1 (screen operation system main control processing unit) of the main controller A shown in FIG. Calculate the conditions described below, calculate the total processing time when transmitting event communication data converted to window change, and calculate the total processing time for the number of change events of the object change display event communication data, and calculate the object change. If the total processing time of the event communication data is longer than the total processing time of the window change event communication data, data transmission to the remote MMI device is performed using the window change event communication data.

Now, the data length of the window change event communication data shown in FIG. 13A is represented by the following equation (1) (unit is [byte]). W.Event.Data.Len = M + N + (V × 2) + P + (n1 + n2 + ...) ... (1) The data length of an object change event communication data shown in FIG. (B) is represented by the following formula (2) (Unit is [bytes]).

O.Event.Data.Len = M + N + n1 (2) Here, Obj.
Value Even time used to interrupt one packet data
Assuming that t.Loss.Time and the number of data bytes that can be transmitted per second by the communication used by the system is Comm.Rate, the window change event communication data transmission time W.Event.Send.Time and object change event communication data transmission Time O.
Event.Send.Time is represented by the following equations (3) and (4) , respectively.

W.Event.Send.Time = W.Event.Data.Len / Comm.Rate [sec] (3) O.Event.Send.Time = O.Event.Data.Len / Comm.Rate [sec] ] (4) Therefore, the transmission time of the window change event communication data
Between W.Event.Send.Time and the transmission time O.Event.Send.Time of the object change event communication data, W.Event.Send.
If the relationship of Time ≦ O.Event.Send.Time is established, the total processing time required for communication is shorter when data is transmitted using window change event communication data as a change in the entire window than when data is transmitted using object change event communication data. That is, it is possible to efficiently perform processing when an object changes.
