Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a display device capable of quickly selecting and displaying a required screen from a large number of screens.

[0002]

2. Description of the Related Art Conventionally, in a display device such as a CRT,
If there are many screens to be displayed on the display screen, first create a menu area on the display screen and assign a screen name that identifies the screen to this menu area, then select from the screen names in this menu area. The required screen name is selected and the required screen is displayed.
However, since the size of the menu area on the display screen is usually limited, it is difficult to assign the screen names of all the screens to the menu area.

Therefore, at present, there are a method in which the menu structure of the screen names assigned to the menu area has a hierarchical structure, and a method in which the screen names are sequentially assigned and updated in the menu area according to the frequency of use of the screen.

Of these two methods, the former method, in particular, registers the screen names of these screens with a group of a plurality of screens assumed to be higher screens out of a large number of screens as a menu of the first layer. In addition, a group of lower screens connected to the screens of the first layer is used as a menu of the second layer, the third layer, ... And those screen names are registered.

Therefore, when displaying a screen using such a hierarchical structure, if there is no screen name of the corresponding screen in the menu of the first layer, the menu of the second layer is displayed, and the menu of the second layer is displayed. If there is no screen name of the corresponding screen, the menu of the next lower hierarchy is displayed, that is, a so-called corresponding screen is sequentially lowered to find a desired screen. Further, when the corresponding screen is composed of a plurality of pages, the page is displayed by performing a page change operation as necessary.

[0006] Next, the latter method is to successively update the screen name of the menu area according to the frequency of use, and will be described below based on the block shown in FIG. 7. That is, according to this method, a fixed menu display section 51 arranged along the horizontal direction on the upper side of the screen and an automatic allocation menu display section 52 for allocating screen names (screen numbers) in descending order of frequency of use along the vertical direction on the right end. Display screen 5 with
3, a screen call detection unit 54 that detects which screen name is being called when a screen name on the automatic allocation menu display unit 52 is touched, specified with a mouse or keyboard, and a buffer memory 55 is used. After incrementing the screen call count of the screen name being called,
A frequency-of-use update setting unit 57 is provided for performing a sorting process in descending order of the number of screen calls and setting the number of times of screen calls corresponding to screen names in the frequency of use of the frequency-of-use table 56.

The use frequency update table 56 is used so that the use frequency table 5 corresponds to the number of m screens, for example.
8. A screen name table 59 and a screen call count table 60 are provided so as to make pairs.

That is, in the case of a menu incorporating a conventional hierarchical structure, a screen which is assumed to be frequently used is preset to 1
About 0 items are selected and assigned to the automatic assignment menu display unit 52, and correspondingly registered in the usage frequency table 56. When the screen call detection unit 54 detects that the screen name is called from the automatic allocation menu or the conventional fixed menu, the usage frequency update setting unit 57 counts the number of times the screen name of the called screen is called, After rearranging in the order of the number of times of calling, the screen name and the number of times of calling the screen are updated in a pair according to the usage frequency ranking of the usage frequency table 56. Here, the usage frequency table 56
Sequentially assigns screen names to the automatic assignment menu display section 52 according to the updated contents of the table 56.

[0009]

Therefore, the display device such as the CRT described above sequentially updates the order of the screen names assigned to the automatic assignment menu display section 52 according to the frequency of use of the screen. The following inconvenient problems occur when the person or work content changes.

A. That is, the automatic allocation menu display unit 52
Since the order of assigning screen names is changed according to the frequency of use of the screen, if the screen user changes or the work content changes, the menu content of the screen name assigned to the menu display section 52 also changes significantly. Will end up. For example, screen user A assigns a screen name that is convenient for him / herself, but if another screen user B uses the screen under different work content, the screen name that is convenient for screen user B is Since the allocation is performed, when the user A tries to use the screen again, the order of the screen names in the menu area is completely changed, and as a result, the advantage of updating the order of the screen names according to the frequency of use is fully realized. There is a problem that cannot be used.

B. Furthermore, since all the screens are subject to updating, there is a problem that even a screen name that does not need to be allocated to the automatic allocation menu display unit 52 is allocated to the menu display unit 52 in the form of the screen name. For example, if there is a second level menu screen under the first level menu screen and many screens are under the second level menu, the screen name of the second level menu is always selected each time a certain screen is expanded. Therefore, there is a problem that the number of times of calling the menu screen of the screen of the second layer increases, and the menu screen is always assigned to the higher order of the automatic assignment menu display unit 52.

C. When the screen user sequentially selects and operates the screens according to the work content, the allocation order of the screen names of the automatic allocation menu display unit 52 changes every time the screen selection operation is performed. As a result, the screen names assigned to the automatic assignment menu display unit 52 are constantly changed, which makes the screen users inconsistent in screen selection.
There is a problem that the features of the hierarchically structured menu are impaired and the handling operation becomes complicated.

The present invention has been made in view of the above circumstances, and a display device capable of assigning a screen name of a frequently used screen to each screen user and, in turn, selecting and displaying a desired screen quickly. The purpose is to provide.

Another object of the present invention is to provide a display device in which a screen name which is frequently used can be assigned to each screen user and which screen user can be appropriately identified. It is in.

Still another object of the present invention is to provide a display device capable of allocating screen names of screens while maintaining a predetermined order without updating even screens that do not require allocation.

Still another object of the present invention is to provide a display device in which screen names of screens can be assigned at an appropriate time and the workability of screen selection by a screen user can be improved.

[0017]

In order to solve the above-mentioned problems, the invention according to claim 1 has a display screen having an automatic allocation menu display section to which frequently-used screen names are allocated, and each screen user. Each screen user is identified based on the screen user identification data input from the outside and the screen user identification frequency storage means for storing the screen name and the number of screen calls for each screen.

The screen user identification section 6 identifies the current screen user while comparing the user identification data input from the outside with the reference data defined in the screen user reference memory 8, and According to the identification result, the display portion of the screen user identification display unit 4 corresponding to the screen user is displayed.

The screen call detection unit 7 has a function of detecting which screen name is called when a certain area of the menu display units 2 and 3 on the display screen 1 is designated by a touch or a mouse. . For example, if the relationship between the coordinate data of each screen name area of each menu display section 2 and 3 and the coordinate data rank is known in advance, touching an area portion of the menu display section 2 and 3 will cause the touch coordinate data to be touched. It is possible to easily determine the screen name and the like from the order of the screen and the screen use frequency order in the screen user-use frequency table described later.

Reference numeral 9 denotes a screen-user-by-screen-user-use frequency update setting unit, which is based on the screen user identification result of the screen user identification unit 6 and the screen name detection result of the screen call detection unit 7.
A function of updating the screen call frequency corresponding to the screen name by selecting the screen user correspondence table in the screen user frequency of use table 10 and changing and setting the screen usage frequency order from the size of these screen call frequencies It has a function.

This screen usage frequency table for each user 10
Preferably has the same number of tables 10 ₁ , as the number of screen users.
10 ₂ , ..., 10 _n are provided, and each of these tables 10
_1, the ... respectively screen numbers table 11 as shown in FIG. 4, a screen name table 12, a screen call number table 13 is sequentially updated, the screen update target flag table 14, the frequency of use order pointer table 15 Are provided in a number corresponding to the number of screens in pairs.

The screen number table 11 is simply provided with serial numbers for distinguishing the screens, and the screen name table 12 shows the screen names of the screens to be displayed on the display screen 1 with appropriate characters, numbers, and numbers. It is described in a form that can be distinguished from other screens by using an alpha bed or the like. The screen call count table 13 is + when the screen name is called.
It is incremented by 1.

The screen update target flag table 14 is
In particular, there are screens that do not need to update the number of screen calls, such as screen selection menu screens and screens that require the screen names to be ranked in advance according to their importance, and screens that require the screen call frequency to be updated. It has a function to set a flag for distinguishing. On the other hand, the use frequency order pointer table 15 sets a number indicating a screen number or a rank which is the next use frequency. Separately from this, in order to store the first screen number in order of frequency of use, a first screen number table 16 is provided separately. Therefore, in this device, the screen number or the order number set in the first-rank screen number table 16 indicates the first rank of the screen use frequency,
The screen number or order number set in the use frequency order pointer table 15 of the screen number table 11 set in the first place screen number table 16 indicates the screen use frequency order second place, and further the use frequency order pointer table. The screen number or rank number set in the frequency-of-use order pointer table 15 corresponding to the screen number table 11 of the screen number or rank number set to 15 indicates the screen use frequency rank 3rd place. Therefore, if the contents of the 1st place screen number table 16 and the use frequency order pointer table 15 are sequentially followed, the contents indicate the screen use frequency order.

The screen user-by-user usage frequency table 10
Is provided with an update time setting table 17. In this table 17, for example, 9:00 am and 5:00 pm are set for each screen user or for each screen user, or a required time is set in consideration of the working status of the screen to be used. When the time is exceeded, a screen name will be assigned to the automatic assignment menu display unit 3.

Reference numeral 18 compares the current time obtained from the clock built in the apparatus with the update time of the update time setting table 17,
When the current time exceeds the update time, it is a menu screen update time determination unit for instructing the screen user-specific use frequency update setting unit 9 to change the screen use frequency ranking. Therefore, when the screen user's usage frequency update setting unit 9 receives an instruction from the menu screen update time determination unit 18, the table 1
Based on the size of the screen call frequency of 0i (i is an integer) of the screen call frequency table 13, ..., the screen use frequency rank is sequentially assigned to the first screen number table 16 and the use frequency order pointer table 15 by the screen number or the order number. Change and set.

Next, the operation of the display device configured as described above will be described with reference to FIGS. First, when the apparatus is started up, the screen-user-by-user usage frequency update setting unit 9 sets a necessary portion of the screen-user-by-user usage frequency table 10, for example, the screen call count table 13, and a 1st screen screen number if necessary. The table 16, the use frequency order pointer table 15 and the like are initialized (ST1). Further, the screen user identification section 6 reads the current screen user identification data input from the keyboard or the like when the apparatus is started up and displays the corresponding portion of the screen user identification display section 4 of the display screen 1 (ST2).

Thereafter, the screen-user-specific usage frequency update setting unit 9 sets the first-screen screen number table 16 and the usage-frequency-ordered pointer table 15, ... As the initial values of the screen-user-specific usage frequency table 10, respectively. Set screen numbers or simple order numbers (numbers) in the order of screen names that are assumed to be high. That is, the tables 16 and 1 are arranged in the order of screen names which are assumed to be used frequently.
5, ... For example, “10”, “9”, “8”, ...
Set "2" and "1". “0” is set in the frequency-of-use pointer table 15, ... Corresponding to other screen names.
Set.

Here, when a screen allocation instruction is given to the table 10 from the use frequency update setting unit 9 for each screen user, the screen use set in the 1st place screen number table 16 and the use frequency order pointer table 15 ,. The screen name is read from the corresponding screen name table 12 based on the frequency ranking, the screen names are sequentially allocated to the automatic allocation menu display unit 3, and the screen names are displayed (ST3). The screen number or the order number set in the 1st screen number table 16 and the use frequency order pointer table 25, ... When the device is started up is set by the device manufacturer in consideration of the screen usage status of the user.

Then, it is judged whether or not maintenance is underway (ST4). When the screen user performs maintenance, the maintenance display section 5 is lit and displayed in advance by a key operation or the like, so that the presence or absence of maintenance is determined from the operating state of the display section 5 or the like. Here, when it is determined that maintenance is in progress, all the following processes are not performed even if there is a screen operation. When it is determined that the maintenance is not being performed, it is determined whether the screen user is changed (ST5). This compares the identification result of the screen user identification unit 6 with the current display state of the screen user identification display unit 4. If they are different, it is determined that the screen user has been changed, and the screen user identification display unit 4 is changed (ST6), the table 10i corresponding to the current screen user in the table 10 is selected based on the identification result of the screen user identification unit 6 (ST7), and the table related to the screen user is selected. Based on 10i, the screen names are allocated and displayed on the automatic allocation menu display section 3 in order of frequency of screen use (ST8). If the screen user is not changed in step ST5, the screen is selected according to the screen name already assigned to the automatic assignment menu display unit 3.

In this state, when there is a calling instruction by touching a screen name on the automatic allocation menu display section 3 of the display screen 1 with a mouse, a keyboard or the like, the screen call detecting section 7 detects that a screen operation has been performed. With (S
T9), it is judged which screen name has been called and whether or not to update from the update target flag table 14 corresponding to the screen name (ST10). The number of screen calls in the table 13 is incremented (ST11), and the screen waiting operation is again waited. On the other hand, if it should not be updated, the screen call count is not updated and the screen call operation waits.

At this time, the menu screen update time determination unit 1
8 compares the current time from a time generation source (not shown) with the update time of the update time setting table 17, and determines whether the current time has passed the update time (ST12). Here, when it is determined that the current time has passed the update time, the first screen number table 16 and the use frequency order pointer table 15, in descending order of the number of screen calls corresponding to the screen name already updated, A sorting process for sequentially rearranging the call use frequency ranking is performed (ST13). Thereafter, the screen-user-specific usage frequency update setting unit 9 sets the screen-user-specific usage frequency table 10
When the call use frequency order is assigned to the screen, the screen names are automatically assigned according to the call use frequency order.
And is displayed on the display screen 1 (ST14). After that, it again stands by in the state of waiting for a screen call operation.

Therefore, according to the configuration of the above embodiment, a table is provided for each screen user in the use frequency table 10, and the screen user is handled based on the screen user identification data from the outside. Table is selected, the number of screen calls corresponding to the screen name is updated, the screen usage frequency is sorted, and the screen names are sequentially allocated and displayed on the automatic allocation menu display section 3. Therefore, even if the screen user is different, The screen can be appropriately called and selected based on the screen usage order according to the work content.

Further, the display screen 1 is provided with the screen user identification display section 4, and the screen user identification section 6 compares the screen user identification data from the outside with the display state of the display section 4 and displays the contents. Is not the current screen user, the display of the screen user identification display unit 4 is changed, so that it is possible to easily grasp which screen user is currently operating the screen, and based on the identification of the current screen user, Similarly, since the screen names are allocated to the automatic allocation menu display unit 3 based on the number of times the screen is called, a menu structure unique to the screen user can be constructed, which greatly contributes to the efficiency of screen selection work and the improvement of operability.

Further, data for determining whether or not the screen use frequency ranking is updated based on the number of times the screen is called for each screen name is set in advance, and if this data is judged and not updated, the screen is called despite the fact that the screen is called. Since the number of times the screen is called and the screen use frequency ranking are not updated, it is possible to properly use the screen according to the contents of the screen or the importance of the screen, and it is possible to selectively fix the screen use frequency ranking to improve operability.

Further, the update time is set in advance, and the screen name is not assigned to the automatic allocation menu display section 3 at all times regardless of the change in the number of times the screen is called. When the current time exceeds the update time, the number of times the screen is called. Since screen names are assigned based on the screen usage frequency rankings associated with changes in screens, screen users can select screens based on screen usage frequency rankings that have been fixed to some extent, and it is possible to ensure consistency in screen selection. it can.

In the above embodiment, the use frequency table 10 is provided with the 1st screen number table 16 and the screen number or the order number of the 1st screen use frequency is set. However, the 1st screen number table 16 is eliminated. The screen usage frequency rankings may be set in all the usage frequency order pointer tables 15 ,.
