Description

  Embodiments described herein relate generally to a state transition table display device and a display control program.

A state transition table is known as a technique for defining what action (action) a controlled object such as a robot performs in response to the occurrence of an event and, as a result, changes to what state.
The state transition table has a matrix-like table format, and the row (or column) represents an event for the controlled object, and the column (or row) represents the state of the controlled object before the event occurs. In a cell where a row and a column intersect, what action is taken when a controlled object in a state corresponding to that cell receives an event corresponding to that cell, and as a result changes to what state? Is displayed in the state transition table.

  The number of rows and the number of columns in such a state transition table depends on the type of event and the number of patterns of states to be controlled. For this reason, when the number of event types or state patterns increases with the diversification of events or the diversification of states, the size of the state transition table increases in proportion to the number. When the size of the state transition table is increased, the state transition table cannot be accommodated on one screen of the display. Therefore, it is difficult for the user to recognize the state transition of the control target only by looking at the table.

  The problem to be solved by the present invention is to provide a display device for a state transition table that allows a user to recognize a state transition of a controlled object with a glance.

In one embodiment, the state transition table display device includes display means, assignment means, width setting means, and control means. The display means displays an invitation transition table representing an event in either a row or a column and representing a state on the other. In the state transition table, the top of the row or column representing the event is an event title cell for recording the title of the event, and the top of the column or row representing the state is a state title cell for recording the title of the state. Further, the state transition table divides an intersecting cell where the row and the column intersect into a first cell and a second cell. The state transition table records an action when an event of the event title cell corresponding to the intersecting cell occurs in the state of the state title cell corresponding to the intersecting cell in the first cell, and A state transition table for recording a transition destination state to be a subsequent transition destination in the second cell is displayed. The assigning means assigns one of the states in association with the display mode of the cells that can be displayed by the display means. For each state, the width setting means sets the cell width as the default width for the state in which the display mode is assigned to the transition destination state after the action when the event occurs in the state. Set to a narrower width. The control means sets the display mode of each state title cell of the state transition table to the display mode assigned to the state of the state title cell, and sets the display mode of the second cell of each intersection cell to The title in the state where the title of the transition destination state recorded in the second cell matches the display mode of the recorded state title cell, and the title in which the narrow width is set by the width setting means is recorded. the width of the second cell of said cross-cells corresponding to the state title cell shall be the width less than the default width.

Hereinafter, an embodiment of a state transition table display device will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a block diagram showing a schematic configuration of the state transition table display device 1. The display device 1 includes a processor 11, a main memory 12, an auxiliary storage unit 13, an input unit 14, and a display unit 15.

  The processor 11 mainly includes a CPU (Central Processing Unit) and performs arithmetic processing according to various programs including a display control program. The main memory 12 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and temporarily stores programs and data. The auxiliary storage unit 13 includes an HDD (Hard Disk Drive) device, an SSD (Solid State Drive) device, or the like, and functions as an area for storing various programs and data such as the state transition table 20 (see FIG. 2). The input unit 14 is a mechanism that receives data input and operation instructions, and uses a keyboard, a mouse, or the like. The display unit 15 is a mechanism that displays the state transition table 20, input data, and the like. For example, a liquid crystal display is used.

  FIG. 2 is a layout example of the state transition table 20. The state transition table 20 represents events for the controlled object by rows, and represents the current state of the controlled object by columns. The top of the row is an event title cell 21 for recording the title of the event (event E1, event E2, event E3, event E4,...), And the top of the column is the title of the state (state S1, state S2, state S3). , State S4,...) Is a state title cell 22 for recording. Further, the state transition table 20 divides an intersecting cell 23 where a row and a column intersect into a first cell 23a and a second cell 23b in the column direction. Then, with respect to the control object in the state of the state title cell 22 corresponding to the intersecting cell 23, the action of the control object when the event of the event title cell 21 corresponding to the intersecting cell 23 occurs (action Axy: x, y = 1, 2, 3, 4,...) is recorded in the first cell 23a, and the state Sx of the control target that is the transition destination after the action is recorded in the second cell 23b.

  In the state transition table 20 having such a configuration, in the present embodiment, the display mode of each state title cell 22 of the state transition table is made different for each cell, and the display mode of the second cell 23b of each intersecting cell 23 is The title of the state to be the transition destination recorded in the second cell 23b is made to match the display mode of the state title cell 22 recorded. Specifically, the background color of each state title cell 22 in the state transition table is made different for each cell, and the background color of the second cell 23b of each intersecting cell 23 is recorded in the second cell 23b. The title of the state to be the transition destination is matched with the background color of the state title cell 22 in which the title is recorded.

  In order to display such a state transition table 20 on the display unit 15, the state transition table display device 1 stores the event table 31, the state table 32, and the action table 33 having the area structure shown in FIG. 3 in the auxiliary storage unit 13. To do.

  The event table 31 records a title (event name) representing the event in association with the event codes E1, E2, E3, E4,... Assigned for each event in order to individually identify various events for the controlled object. .

  The state table 32 is associated with the state codes S1, S2, S3, S4,... Assigned to each state in order to individually identify various state patterns in the control target, and the state names and color codes C1, C2,. .. And C3, C4,... And the number of appearances N1, N2, N3, N4,. The color codes C1, C2, C3, C4,... Are codes that specify the background color of the state title cell 22 in which the state names specified by the corresponding state codes S1, S2, S3, S4,. The number of appearances N1, N2, N3, N4,... Is the number of times the state of the state name specified by the corresponding state code S1, S2, S3, S4,.

  The action table 33 records an action name and a transition destination state code for each combination of the event codes E1, E2, E3, E4,... And the state codes S1, S2, S3, S4,. The action name indicates the action of the control target when the event specified by the corresponding event code occurs with respect to the control target in the state specified by the corresponding status code. The transition destination state code is a state code corresponding to the state of the control target after the action with the corresponding action name is performed. If the state of the control target does not change after the action with the corresponding action name is performed, the transition destination state code is indicated by “−”. In addition, when the control target does not act even if the event specified by the corresponding event code occurs for the control target in the state specified by the corresponding state code, both the action name and the transition destination state code are It is indicated by “−”.

  Also, the state transition table display device 1 forms a background color table 41 having an area structure shown in FIG. 4 in the main memory 12 in order to determine the background color of each state title cell 22 in the state transition table 20. The background color table 41 includes a color code area and a status code area for each color ID. The color ID is an identification code of a cell background color that can be displayed on the display unit 15.

  Furthermore, the state transition table display device 1 determines the width of the second cell 23b of each intersecting cell 23 in the state transition table 20, that is, the so-called transition destination cell 23b, in a cell width table 51 having an area structure shown in FIG. Are formed in the main memory 12. The cell width table 51 includes a transition destination cell width area for each status code. In the transition destination cell width area, a default value D1 of the transition destination cell width is set in advance. In the information processing according to the display control program described later, the default value D1 is selectively replaced with the cell width minimum value MIN. Incidentally, the default value D1 is set to a value equal to the width of the first cell 23a in which the action name of each intersecting cell 23 is recorded, that is, the so-called action cell 23a. On the other hand, the cell width minimum value MIN is a width that allows the user to visually recognize the background color of the transition destination cell 23b, and is an arbitrary value (0 <MIN <D1) that is sufficiently small.

  The state transition table display device 1 having such a configuration mounts the editing program for the state transition table 20 and the display control program in the main memory 12 or the auxiliary storage unit 13 which is a program storage unit. When an editing job for the state transition table 20 is selected via the input unit 14, the processor 11 executes data reception processing for the event table 31, the state table 32, and the action table 33 according to the editing program.

  The data reception process includes an event name reception mode, a state name reception mode, and an action name and a transition state code reception mode. When the event name reception mode is selected, the processor 11 stores the event names input via the input unit 14 in the event table 31 in ascending order of event codes, for example.

  When the state name acceptance mode is selected, the processor 11 stores the state names input via the input unit 14 in the state table 32, for example, in ascending order of the state codes. In addition, unique color codes C1, C2, C3, C4... Are assigned and stored in advance in the color code area of the state table 32, and the appearance counts N1, N2, N3. “0” is stored as the initial value of N4.

  When the action name and transition state code reception mode is selected, the processor 11 sets the event code E1, E2, E3, E4,... In which the event name is set in the event name reception mode, and the state name reception mode. For each combination of the state codes S1, S2, S3, S4,... In which the state names are set, the input of the action name and the state code of the transition destination is accepted. When an action name and a transition destination state code are input via the input unit 14, the action name and the transition destination state code are changed to the corresponding event codes E1, E2, E3, E4,. It stores in the combination area with codes S1, S2, S3, S4,. Further, the number of appearances of the state code set as the transition destination state code in the state table 32 is incremented by “+1”.

  Thus, when the event name, state name, action name, and transition destination state code are stored in the event table 31, the state table 32, and the action table 33, respectively, the state transition table display device 1 displays the state transition table 20. Can be executed. When a display job is selected via the input unit 14, the processor 11 executes display control processing of the state transition table 20 according to the display control program.

  The procedure of this display control process will be described in detail with reference to the flowcharts of FIGS. That is, when the display control program is activated, the processor 11 checks whether or not the number of state names stored in the state table 32 exceeds the number of cell background colors that can be displayed on the display unit 15 (ST1). If the number of state names does not exceed the number of cell background colors (NO in ST1), processor 11 determines the color code set for the state code storing the state name in state table 32. Are extracted together with the corresponding status code, and a pair of data of the extracted color code and status code is stored in the background color table 41 (ST2). At this time, there is no particular limitation on which color ID of the background color table 41 stores the pair of data of the color code and the status code. The processor 11 may store a pair of data of a color code and a status code in the background color table 41 according to an arbitrary rule.

  If the number of state names exceeds the number of cell background colors (YES in ST1), processor 11 refers to state table 32 and appears as color codes C1, C2, C3, C4. Number of times N1, N2, N3. N4... Are acquired (ST3). Then, the processor 11 assigns each color code C1, C2, C3, C4... To the corresponding appearance count N1, N2, N3. It rearranges in order with many N4 ... (ST4). Thereafter, the processor 11 determines that the appearance count N1, N2, N3. A pair of data of the color codes C1, C2, C3, C4... Rearranged in the descending order of N4 and the status codes S1, S2, S3, S4. . N4... Are stored in the background color table 41 in descending order (ST5). Also in this case, there is no particular limitation on which color ID of the background color table 41 stores the pair of data of the color code and the status code. The processor 11 follows the arbitrary rules, and the number of appearances N1, N2, N3. A pair of data of color code and status code may be stored in the background color table 41 in the order of N4.

  When the color code and the status code are stored in the background color table 41 by the process of step ST2 or step ST5, the processor 11 resets the counter n to “0” (ST6). Next, the processor 11 counts up the counter n by “1” (ST7). Then, the processor 11 checks whether or not the counter n is equal to or smaller than the number of state names stored in the state table 32 (ST8).

  If counter n is equal to or less than the number of state names (YES in ST8), processor 11 searches action table 33 and for each of event codes E1, E2, E3, E4,. All the transition destination state codes stored corresponding to the value of the counter n) are acquired (ST9). Then, the processor 11 checks whether or not each acquired transition destination state code exists in the state code area of the background color table 41 (ST10).

  When all the acquired transition destination state codes are present in the state code area of the background color table 41, all the background colors are set for the state title cells 22 in the state specified as the transition destination by the transition destination state code ( YES at ST10). In this case, the processor 11 rewrites the transition destination cell width corresponding to the state code in the cell width table 51 from the default value D1 to the minimum value MIN (ST11). After that, the processor 11 returns to the process of step ST7. Then, the processor 11 further increments the counter n by “1”, and executes the processes after step ST8 again.

  On the other hand, when at least one of the acquired transition destination status codes does not exist in the status code area of the background color table 41, the status title cell 22 in the state specified by the transition destination status code as the transition destination Includes a cell whose background color is not set (NO in ST10). In this case, the processor 11 returns to the process of step ST7 without executing the process of step ST11. Then, the processor 11 further increments the counter n by “1”, and executes the processes after step ST8 again.

  Thus, until the counter n exceeds the number of state names, the processor 11 repeatedly executes the processes of steps ST9 to ST11. That is, the processor 11 acquires all the transition destination state codes stored corresponding to the state code Sn for each event code E1, E2, E3, E4,..., And the acquired transition destination state codes are all stored in the background color table. Only when it exists in the state code area 41, the transition destination cell width corresponding to the state code in the cell width table 51 is rewritten from the default value D1 to the minimum value MIN.

  If counter n exceeds the number of state names (NO in ST8), processor 11 creates state transition table 20 based on the data of event table 31, state table 32, and action table 33 (ST12). ).

  Specifically, the processor 11 expands the format of the state transition table 20 in the work area of the main memory 12. Then, the processor 11 records the event names of the event table 31 in the order of the event codes in each cell of the first row in the state transition table 20 and sets it as the event title cell 21. Further, the processor 11 records the state names of the state table 32 in the order of the state codes in each cell of the first column in the state transition table 20, and sets the state title cell 22.

  Further, the processor 11 stores the event code Ey (y = 1, 2, 3, 4,...) Of the event name recorded in the corresponding event title cell 21 in the first cell (action cell) 23a of each intersection cell 23. And the action name stored in the action table 33 in association with the state code Sx (x = 1, 2, 3, 4,...) Of the state name recorded in the corresponding state title cell 22 is recorded. Further, the processor 11 associates the action name recorded in the action table 33 with the action name recorded in the second cell (transition destination cell) 23b of each intersecting cell 23. Record the state name.

  After creating the state transition table 20 in this way, the processor 11 adjusts the cell width of the second cell 23b in the intersecting cell 23 for each column to which the state title cell 22 is assigned. That is, the processor 11 searches the cell width table 51 to find a status code in which the transition destination cell width is updated to the minimum value MIN. Then, the processor 11 sets the width of the second cell 23b of each crossing cell 23 corresponding to the state title cell 22 in which the state name of the state code whose transition destination cell width has been updated to the minimum value MIN to the minimum value. Adjust to MIN (ST13). Further, the processor 11 erases the transition destination state name recorded in the second cell 23b in order to make the transition destination state name invisible from the second cell 23b whose cell width is adjusted to the minimum value MIN (ST14). ). Further, the processor 11 reads the status codes from the background color table 41 in the order of color IDs, for example. The processor 11 then sets the background color for the state title cell 22 in which the state name of the state code is set and the second cell 23b of the intersecting cell 23 in which the state code is set as the transition destination state code. The color of the color ID corresponding to the status code is set (ST15).

  Here, the processor 11 that executes the processes of steps ST13, ST14, and ST15 constitutes control means. In addition, the processing order with step ST13, ST14, ST15 is not limited to the said embodiment, You may perform in any order.

  Thereafter, the processor 11 causes the display unit 15 to display the state transition table 20 created by the process of step ST12 and adjusted by the processes of steps ST13 to ST15 (ST16). Here, the display unit 15 for displaying the state transition table 20 constitutes display means.

  After that, the processor 11 waits for the display end of the state transition table 20 to be input via the input unit 14 (ST17) or for one of the second cells 23b in each intersection cell 23 to be instructed ( ST18). For example, when a pointer that moves on the screen by an operation input of the input unit 14 is placed on any of the second cells 23b, the processor 11 considers that the second cell 23b has been selectively input. Here, the input unit 14 constitutes input means.

  If one of the second cells 23b is instructed (YES in ST18), the processor 11 confirms whether or not the cell width of the instructed second cell 23b is the minimum value MIN ( ST19). If the cell width is not the minimum value MIN (NO in ST19), the processor 11 proceeds to the process of step ST22 without executing the processes of steps ST20 and ST21.

  On the other hand, when the cell width of the second cell 23b input as an instruction is the minimum value MIN (YES in ST19), the processor 11 erases from the second cell 23b in the process of step ST14. The made transition destination state name is displayed in the form of a balloon for the second cell 23b (ST20). Further, the processor 11 thickens the frame of the state title cell 22 in which the transition destination state name erased from the second cell 23b is recorded, and highlights the state title cell 22 (ST21). Thereafter, the processor 11 proceeds to the process of step ST22.

  In step ST22, the processor 11 determines the width of the state column other than the state column including the state cell including the input second cell 23b and the state name of the state code recorded in the second cell 23b. Is contracted to approximately “0”. That is, the processor 11 assigns the state transition table 20 displayed on the display unit 15 to the state string including the second cell 23b that has been instructed and the state name of the state code recorded in the second cell 23b. Filters only to the specified status column.

  After that, the processor 11 waits for the instruction input to the second cell 23b to be released (ST23). For example, when the pointer moves from the second cell 23b, the processor 11 considers that the instruction input to the second cell 23b has been released. When the instruction input in second cell 23b is canceled (YES in ST23), processor 11 confirms whether or not the transition destination state name has been displayed in a balloon format (ST24).

  If the transition destination state name is not displayed in the balloon format (NO in ST24), the processor 11 proceeds to the process of step ST27. On the other hand, when the transition destination state name is displayed in a balloon format (YES in ST24), processor 11 deletes the balloon display (ST25). Further, the processor 11 releases the highlighted display of the state title cell 22 in which the transition destination state name is recorded (ST26). Thereafter, the processor 11 proceeds to the process of step ST27.

In step ST27, the processor 11 restores the state sequence contracted in the process of step ST22 to the original size.
Thereafter, the processor 11 returns to the process of step ST17 and waits for the display end of the state transition table 20 to be input or for one of the second cells 23b to be input. When the second cell 23b is input again (YES in ST18), the processor 11 repeatedly executes the processes in steps ST19 to ST27.

  On the other hand, when the display end of state transition table 20 is input (YES in ST17), processor 11 stores the data of state transition table 20 in auxiliary storage unit 13 (ST28). Further, the processor 11 deletes the state transition table 20 from the display unit 15 (ST29). This completes the information processing according to the display control program.

  FIG. 8 is an example when the state transition table 20A created in the process of step ST12 is displayed on the display unit 15 as it is. At step ST12, the action name is recorded in the first cell 23a of the intersecting cell 23, and the transition destination state name is recorded in the second cell 23b. For this reason, as shown in FIG. 8, since both the first cell 23a and the second cell 23b have a width necessary for recording names, the state transition table 20A becomes longer in the column direction. As a result, the number of status title cells 22 (four in the figure) that can be displayed on one screen is small.

  FIG. 9 is an example of the state transition table 20B displayed on the display unit 15 in the process of step ST16. However, since the background color of the cell cannot be expressed in the drawing, a color code Cj (j = 1, 2, 3, 4,...) Representing the color is described in the cell for which the background color is set. Incidentally, the example of FIG. 9 shows a case where no color ID is set for the state S30. In this case, for the column of the state S1 in which the state S30 is included in the transition destination, the cell width of the second cell 23b remains the initial value D1. However, for the columns of the other states S2, S3, S4, S5, and S6 in which the state S30 is not included in the transition destination, the cell widths of the second cells 23b are all the minimum value MIN. For this reason, as shown in FIG. 9, the length of the state transition table 20B in the column direction is shorter than that of the state transition table 20a. As a result, the number of status title cells 22 (six in the figure) that can be displayed on one screen increases.

  Here, the transition destination state name is erased from the second cell 23b having the minimum value MIN. However, the background color is set in the second cell 23b. The background color matches the background color of the state title cell 22 in which the same state name as the transition destination state name recorded in the second cell 23b is recorded. Therefore, the user performs any action by the control target in the state of the state title cell 22 corresponding to the second cell 23b in response to the event occurrence of the event title cell 21 corresponding to the second cell 23b. It is possible to visually grasp the state of change. Although the transition destination state name cannot be confirmed from the second cell 23b, the transition destination recorded in the second cell 23b is the state name of the state title cell 22 of the same color. The state name can be recognized correctly.

  10 and 11 are display examples when the user selectively inputs an arbitrary second cell 23b-3 to the state transition table 20B. As shown in FIG. 10, when the user inputs an instruction for the second cell 23b-3 in which the transition destination state name is not displayed, the state transition table display device 1 records the second cell 23b-3 in the second cell 23b-3. The transition destination state name is displayed in a balloon 24 format. Further, the border line of the state title cell 22-1 in which the state name displayed in the form of the balloon 24 is recorded becomes thick and highlighted.

  Subsequently, in the state transition table display device 1, a column other than the column including the state title cell 22-3 including the input second cell 23b-3 and the column of the highlighted state title cell 22-1. Is shrunk. As a result, as shown in FIG. 11, the state columns displayed in the state transition table 20 are narrowed down to the columns before the transition and the columns after the transition. Therefore, the user transitions to any state as a result of the control target in the state title cell 22 corresponding to the selected second cell 23b-3 acting in response to the event occurrence in the corresponding event title cell 21. Can always be confirmed visually on one screen.

[Second Embodiment]
In the first embodiment, the cell width minimum value MIN of the second cell (transition destination cell) 23b is a width that allows the user to visually recognize the background color of the second cell 23b, and is a sufficiently small arbitrary value. (0 <MIN <D1). In the second embodiment, the cell width minimum value MIN is defined as “0”.

  In the first embodiment, in the process of step ST15 in FIG. 6, the processor 11 is in the same state as the state title cell 22 in which the state names of the state codes read from the background color table 41 in the order of the color IDs are set. For the second cell 23b of the intersecting cell 23 in which the code is set as the transition destination state code, the background color is set to the color ID corresponding to the state code. In the second embodiment, the processor 11 includes a state title cell 22 in which the state names of the state codes read from the background color table 41 in the order of color IDs are set, and an intersection in which the state codes are set as transition destination state codes. For the first cell 23a of the cell 23, the background color is set to the color of the color ID corresponding to the status code.

  FIG. 12 is an example of the state transition table 20C displayed on the display unit 15 in the process of step ST16 in the second embodiment. However, since the background color of the cell cannot be expressed in the drawing, a color code Cj (j = 1, 2, 3, 4,...) Representing the color is described in the cell for which the background color is set. Incidentally, the example of FIG. 12 shows a case where no color ID is set for the state S30, as in the example of FIG. 9 of the first embodiment. In this case, for the column of the state S1 in which the state S30 is included in the transition destination, the cell width of the second cell 23b remains the initial value D1. However, for the columns of the other states S2, S3, S4, S5, S6, and S7 in which the state S30 is not included in the transition destination, the cell widths of the second cells 23b are all the minimum value MIN. For this reason, as shown in FIG. 12, the second cell 23b is omitted from the columns of the states S2, S3, S4, S5, S6, and S7. As a result, the number of status title cells 22 (seven in the figure) that can be displayed on one screen is further increased than in the first embodiment.

  In the columns of the states S2, S3, S4, S5, S6, and S7 in which the second cell 23b is omitted, the background color of the first cell 23a is the transition destination state name recorded in the corresponding second cell 23b. Matches the background color of the state title cell 22 in which the same state name is recorded. Therefore, as in the first embodiment, the user can control whether the control target in the state of the state title cell 22 corresponding to the first cell 23a generates an event in the event title cell 21 corresponding to the first cell 23a. It is possible to visually grasp what kind of action is taken in response and what kind of state the result changes.

The present invention is not limited to the above embodiments.
For example, in each of the above embodiments, as shown in FIG. 2, the event for the control target is represented by a row, and the state transition table 20 representing the current state of the control target by a column is shown. However, the present invention is not limited to this. For example, an event for a control target may be represented by a column, and a current state of the control target may be represented by a row. Further, the intersecting cell 23 where the row and the column intersect may divide the first cell 23a and the second cell 23b in the row direction.

  In each of the above embodiments, the background color is changed in order to change the display mode of the state title cell 22 for each cell. However, the display mode to be changed is not limited to the background color. For example, the display mode of the state title cell 22 may be varied for each cell by changing the expression of the cell shading pattern, texture, frame line, or the like.

  Further, in each of the above embodiments, the state title cell 22 is highlighted by making the frame line thick, but the highlighting method is not limited to this. For example, the state title cell 22 may be highlighted by changing the characters displayed in the state title cell 22 (bold, italic characters, etc.), blinking a frame or background, and combinations thereof.

  Moreover, in each said embodiment, although the state transition table display apparatus 1 mounted the edit program of the state transition table 20, it is not necessarily required to mount. The state transition table display device 1 downloads each data of the event table 31, the state table 32, and the action table 33 edited by other devices to the state transition table display device 1 through the communication means, so that the state transition table display device 1 20 display tasks may be executed.

  In each of the above embodiments, a control program for realizing the functions of the invention is recorded in advance in a program storage unit in the apparatus. However, the present invention is not limited to this, and a similar program may be downloaded from the network to the apparatus. Alternatively, a similar program recorded on the recording medium may be installed in the apparatus. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by the apparatus. Further, the function obtained by installing or downloading the program may be realized in cooperation with an OS (operating system) in the apparatus.
