Abstract

PURPOSE:To facilitate a change in design and specification by determining a picture transiting destination from picture transition information and outputting picture display information. CONSTITUTION:When an input is received from a keyboard, the picture transition information corresponding to a picture identifier currently during conversation stored in the table of an information memory part in advance is referred, and it is judged whether the key input is coincident with a key input to start picture transition or not. When the key inputs are coincident with each other, it is decided that the picture transition is established, and an arithmetic formula defined in advanced in advance is calculated while referring to variable and arithmetic formula information corresponding to the picture identifier of the transiting destination stored in the table of the information memory part in advance. Continuously, picture display data corresponding to the picture identifier of the transiting destination are referred and the display data are outputted to a place designated by display position data. Thus, since concrete processing contents can be realized by the arbitrary definition of the variable and arithmetic formula in the unit of a picture without depending on calling parts, the design and specification can be easily changed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a conversation processing control method and device in a conversation processing system such as a PO8 terminal or a bank branch terminal, and particularly to a conversation processing control method and device for conversation screen transitions, displays, etc. The present invention relates to a conversation processing control method and device suitable for changing designs and specifications regardless of differences.

[Prior Art] Conventionally, conversation processing systems that proceed with processing in the form of conversation between an operator and a terminal have been widely introduced in retail stores, supermarkets, department stores, banks, and the like. For example, P.

In S terminals, bank branch terminals, etc., the operator inputs data into the terminal, and based on the input data, the terminal prompts the operator to input the next data, and so on.

Conversation processing systems like this often require unique processing for each customer due to differences in the business structure of the customer and how they are characterized relative to competitors, so they are designed and developed based on customer-specific specifications. I was going. Furthermore, even after the system is operational, because processing proceeds in a conversational format between the operator and the terminal, there may be requests for specification changes in terms of operating procedures or usability, which requires a great deal of effort to respond to. Ta.

To address these problems, a control method has been proposed that does not depend on specific processing content and can be formulated by repeating the same procedure.

For example, as described in Japanese Unexamined Patent Publication No. 1-99160, each conversation screen includes a pre-processing table that specifies the process to be performed before conversation processing, a key processing table that specifies the process to be performed during conversation processing, It has been proposed to provide post-processing tables that define the processing to be performed after the end of conversation processing, perform processing during the conversation state based on these tables, and change the conversation state using screen identifiers.

As a result, it is possible to formulate a control method for conversation processing that was dependent on the processing content by repeating the same procedure, and it is possible to improve the productivity and maintainability of conversation processing system development.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, no consideration is given to the design and specification changes of specific processing contents controlled by the same procedure.

That is, since the specific processing content is registered as a called component, detailed design and specification changes to the specific processing content require remaking or reworking of the called component. Therefore, although it is possible to improve productivity and maintainability by reusing called parts and formulating calling procedures, specific intra-processing decisions that depend on called parts are as complicated as in the past.

The purpose of the present invention is to improve such problems, formulate a control method for conversation processing by repeating the same procedure, and
It is an object of the present invention to provide a conversation processing control method and device whose specific processing contents do not depend on called components and whose design and specifications can be easily changed.

[Means for Solving the Problems] In order to achieve the above object, the conversation processing control method and device of the present invention provide key inputs that trigger screen transitions and transition destinations for each screen identifier defined for each conversation screen. screen transition information consisting of a screen identifier, screen display information consisting of display position data and display data, arithmetic expressions based on combinations of variables and numerical values, and variables to which calculation results of each arithmetic expression are substituted. Variables and calculation formula information are stored in advance in each table of the information storage unit, and each time a key is input, screen transition information corresponding to the screen identifier currently being spoken is referred to,
Depending on whether the key input matches the key input that triggers the screen transition, it is determined whether the screen transition is successful or not. If it is not successful, the key input is waited until it is successful, and if it is successful,
Refer to the variable/arithmetic expression information corresponding to the transition destination screen identifier, calculate the expression in advance, assign the calculation result to the corresponding variable, and then calculate the screen display information corresponding to the transition destination screen identifier. , and if the display data includes a variable, refer to the value of the assigned variable and output the display data to the location specified by display position, then select the key that will trigger the next screen transition. It is characterized by waiting for input.

[Operation] In the present invention, when there is an input from the keyboard, the conversation processing system refers to the screen transition information corresponding to the screen bug currently being conversed, stored in advance in the tableware, and changes the operator's key Determine whether the input matches a key input that triggers a screen transition.

As a result, if they do not match, it is determined that the screen transition has not been established, and the process waits until the operator performs a key input to establish the screen transition.

If they match, it is determined that the screen transition has been established, and the predefined calculation is performed by referring to the variable/operation expression information corresponding to the transition destination screen identifier stored in the table of the information storage section in advance. Calculate the formula.

This calculation result is assigned to the corresponding variable.

Next, the screen display data corresponding to the transition destination screen identifier stored in advance in the tableware is referred to, and the display data is output to the location specified by the display position data. At this time, if the display data includes a variable, the value of the assigned variable is referenced and output.

After the display data is output in this manner, the conversation processing system waits for the operator to perform a key input that will trigger the next screen transition. On the other hand, the operator can know that the screen has finished transitioning by completing the output of the display data, and inputs a key into the terminal to trigger the next screen transition.

As described above, the control method for conversation processing between the operator and the conversation processing system can be formulated by repeating the same procedure, and the specific processing content can be controlled on a screen-by-screen basis for variables and arithmetic expressions without depending on the called component. Since it can be realized by definition, design and specification changes are easy.

Furthermore, as a result of screen transition establishment determination, 3, which is the transition destination screen,
The display data is output with reference to the screen display information table 52 of the screen. At this time, if the display data includes variables, the values of the variables in the variable/arithmetic expression information table 53 of the three screens are referred to and output. Note that the value of the variable is changed to the screen ID immediately after the screen transition is established and the screen ID of the transition destination is determined.
This can be obtained by calculating the arithmetic expression in the variable/arithmetic expression information table 53 corresponding to , and assigning the calculation result to the variable.

In FIG. 12, the variable/arithmetic expression information table 53 on three screens is shown.
In item numbers 1 to 3, the variables "price", "price bow amount", and "selling price" are defined, and each has a value of "300".
","゛Price
, discount amount = price X0, 1 = 300xO, 1 = 30, selling price = price - discount amount = 300-270 = 30.

Therefore, the value of the variable ``Sales price'', which is the display data in item number 2 of the screen display information table 52 for the two screens, is ``270''.
”The value will be output as is.

In this way, when all the display data (including variables) defined in the screen display information table 52 for the three screens is output to the CR1 screen, the screen from the X screen (CRT display screen 54) to the third screen (

In items 1 to 4 of 5, the variables “total”, “price”, “subtotal”°, and “total” are defined.The values of these variables can be obtained in the same manner as in the eighth embodiment. .moreover,
The display data of the screen display information table 68 of the X screen is output and displayed with reference to the calculation results of the preprocessing variable/arithmetic expression information table 65 of the X screen. An example of this display is shown in CR7 display screen 70.

After outputting the display data of this X screen, the post-processing variables of the
Calculation of the arithmetic expression information table 66 is executed. In this case, the variables “tax” and “total amount” are defined in item numbers 1 and 2 of the post-processing variable/arithmetic expression information table 66 on the X screen, and each tax = price x0.03 = 100
X0,03=3, total=total+tax=,100+3=1
We get a result of 03. Note that, as the initial values of "price" and "total", the values calculated in the preprocessing variable/arithmetic expression information table 65 are referred to as they are. In other words, ``price''
, the initial values of ``total'' are ``100'' and ``100'', respectively.
” becomes.

In this way, similarly to the first embodiment, when the screen transition to the second screen is established, the screen display information table 69 for the seven screens is referred to and display data is output. At this time, in item numbers l to 3 of the preprocessing variable/arithmetic expression information table 67 on the 7 screens,
Variables ``Price, Subtotal, and Total'' are defined, and respectively, price = 170, subtotal = subtotal + price =
O+ 170=170, total=total+price=103+1
We get a result of 70=273. Note that ``Subtotal'' is a screen white variable and its initial value is O, but ``Total'' is an inter-screen variable, and its initial value is directly referenced from the value on the previous screen, X screen. In other words, the initial value of "total" for the 7th screen is "103", which is the final value calculated using the post-processing variable/calculation information table 66 of the X screen.
becomes.

Furthermore, 7 screens of preprocessing variable/arithmetic expression information table 67
With reference to the calculation results of
The screen transition from the screen (CR7 display screen 70) to the seventh screen (CR7 display screen 71) is completed.

(Tenth Example) In this example, only when the display conditional expression is satisfied,
The method for outputting display data will be described.

FIGS. 17 and 18 are side views of the screen output in the 1oth embodiment of the present invention.

In FIG. 17, 72 is a screen display information table, 73
is a variable/arithmetic expression information table, and 74 is a CR7 display screen. In this screen display information table 72, display position data, display data (including variables), and display condition expressions based on combinations of variables and numerical values are defined in advance. Further, in the variable/arithmetic expression information table 73, arithmetic expressions, variables, and variable attributes (numeric values or characters) are defined in advance.

In this embodiment, as a result of the screen transition establishment determination shown in the first embodiment, display data is output with reference to the screen display information table 72 of two screens that are transition destination screens. At this time, the variables included in the display data are output in the same manner as in the seventh embodiment. However, the display data is output only when the display conditional expression of the screen display information table 72 is satisfied.

For example, in the screen display information table 72 for two screens, the display condition expression ``number=bi'' is defined in item number 2, and ``number>1'' is defined in item numbers 3 to 5. Further, since no display conditional expression is defined for item number 1, the display data of item number 1 is output unconditionally.

On the other hand, when the calculation of the two-screen variable/arithmetic expression information table 73 is executed in the same manner as in the sixth embodiment, the number of items=1 is obtained. Therefore, among the display conditions of the two-screen screen display information table 72, only item number 2 is satisfied, and the display data of item number 2 is output and displayed. A display example thereof is shown on the CRT display screen 74.

Further, in FIG. 18, 75 is a screen display information table, 76 is a variable/arithmetic expression information table, and 77 is a CR7 display screen.

FIG. 18 shows the configuration of the screen display information table 75, the variable/arithmetic expression information table 76, the procedure for determining whether a screen transition is established,
The calculation of variable values, the reference procedure, and the output method of display data are explained in the first part.
This is similar to FIG. 7, and only the calculation results of the variable/arithmetic expression information table 76 on the two screens are different.

In other words, the variable/arithmetic expression information table 76 on the ziii surface
When the calculation is executed, the number of pieces = 2 is obtained. Therefore, among the display conditional expressions of the two-screen screen display information table 75, item numbers 2 to 5 are satisfied, and the display data of item numbers 3 to 5 are output and displayed. A display example thereof is shown on the CR7 display screen 77.

(Eleventh Embodiment) In this embodiment, a method of executing screen transition only when a transition conditional expression is satisfied will be described.

FIG. 19 is an explanatory diagram showing the process of determining whether a screen transition is established in the eleventh example of this embodiment.

In FIG. 19, 78 is a screen transition information table, 79
is a variable/arithmetic expression information table. This screen transition information table 78 includes key inputs that are key to screen transitions,
A transition destination screen ID and a transition conditional expression that is a combination of variables and numerical values are defined in advance. Further, in the variable/arithmetic expression information table 79, arithmetic expressions and variables are defined in advance.

In this embodiment, the screen currently being used for conversation is the X screen, and the calculations in the variable/arithmetic expression information table 78 for the X screen have already been performed. That is, similarly to the sixth embodiment, a result of price=1500 is obtained. Here, when the operator inputs a key such as Il bI+, the conversation processing system refers to the screen transition information table 78 of the X screen and determines whether the screen transition is successful or not in the same manner as in the first embodiment. . However, the establishment of screen transition is recognized as follows:
This is limited to the case where the transition conditional expression of the screen transition information table 79 is satisfied.

For example, in the screen transition information table 79 of the
” is defined, but price = 150
Since the result is 0, only item number 3 that satisfies the transition conditional expression is valid.

That is, at the stage when the operator 21 inputs the key "b", the x@1iijili screen transition information table 79
The screen transition is established in item number 3, and it can be determined that the screen ID of the transition destination is Z. Furthermore, as a result of the screen transition establishment determination, display data is output with reference to the screen display information table (not shown) for the two screens that are the transition destination screens.

(Twelfth Embodiment) In this embodiment, a method will be described in which calculation of an arithmetic expression is executed only when the arithmetic conditional expression is satisfied.

FIG. 20 is a view of the screen output side in the twelfth embodiment of the present invention.

In FIG. 20, 80 is a screen display information table, 81
is a screen display information table, and 82 is a CR7 display screen. In this screen display information table 80, display positions and display data (including variables) are defined in advance. Also,
In the variable/arithmetic expression information table 81, arithmetic expressions, variables, attributes of variables (numeric or character), variables whose attributes are numeric, and arithmetic condition expressions based on combinations of numeric values are defined in advance.

In this embodiment, as a result of the screen transition establishment determination shown in the first embodiment, display data is output with reference to the screen display information table 80 of two screens that are transition destination screens. At this time, the variables included in the display data are output by executing calculations in the variable/arithmetic expression information table 8 in the same manner as in the seventh embodiment and by referring to the values. However, the calculation is executed only when the calculation conditional expression in the variable/arithmetic expression information table 81 is satisfied.

For example, in the variable/arithmetic expression information table 81 on two screens,
The calculation conditional expression ``'Price >1000'' is defined in Item No. 2, and the calculation in Item No. 1 yields price = 300. Therefore, the calculation conditional expression in Item No. 2 is not satisfied, and Item No. 2 calculation is not performed.

Therefore, in the calculation of the variable/arithmetic expression information table 81 on the two screens, price = 300, selling price = price - discount amount = 300 - 0
= 300, product name = Kutsky.

Further, the display data of the screen display information table 80 of two screens is output and displayed with reference to the calculation results of the variable/arithmetic expression information table 81 of two screens. A display example thereof is shown on the CR7 display screen 82.

(Thirteenth Embodiment) In this embodiment, a case will be described in which a value input using a numeric keypad is assigned to a predetermined variable.

FIG. 21 is a flowchart showing the conversation processing procedure in the thirteenth embodiment of the present invention.

In FIG. 21, 20j is a variable/arithmetic expression information storage unit;
20 is a screen transition information storage section.

In this embodiment, after starting conversation processing, the screen ID is set to the screen ID of the initial screen (100).

Next, refer to the variable/arithmetic expression information corresponding to the screen ID from the variable/arithmetic expression information storage unit 20j (2100), calculate the arithmetic expression, and assign the calculation result to the variable (210).
1). At this time, variables to which the input numeric keypad values are assigned (hereinafter referred to as input variables) are treated in the same way as other variables, but it is prohibited to assign new values to the input variables.

Next, the screen display information corresponding to the screen ID is referenced from the screen display information storage unit 20g (2102), and the CRT 23
(2103). At this time, if the display data includes a variable, the substituted calculation result is referenced in advance in step 2102 and output.

Note that steps 103 and 104 are similar to the conversation processing procedure of the first embodiment.

Furthermore, after the determination in step 104, if the operator's key input does not instruct the end of the conversation process, the screen transition information storage unit 20 refers to the screen transition information corresponding to the screen ID (2104).

Subsequently, the key input from the operator is compared with the screen transition information, and it is determined whether the key input is a key input that establishes a screen transition (2105).

As a result, if the key input does not establish the screen transition, the process returns to step 103 and waits for a new key input.

In addition, if the key input is a screen transition establishment, it is determined whether the operator's key input includes a numeric key input (2106
).

If there is an input from the numeric keypad, the value of the numeric keypad is assigned to the input variable (2107), the screen ID is set as the screen ID of the transition destination screen (107), and the process returns to step 2100. In addition, if there is no numeric key input, step 210
7 and proceed to step 107.

FIG. 22 is an explanatory diagram showing the process of screen transition in the thirteenth embodiment of the present invention.

In FIG. 22, 83 is a screen transition information table, 84
is a screen display information table, 85 is a variable/arithmetic expression information table, and 86 and 87 are CRT display images. In this screen transition information table 83, key inputs that trigger screen transitions and screen IDs of transition destinations are defined in advance. In addition,
Among the key inputs that trigger a screen transition, any numeric key input is represented by °T'. Further, in the variable/arithmetic expression information table 85, arithmetic expressions and variables are defined in advance. This arithmetic expression includes an input variable, and the input variable is represented by T.

In this embodiment, the screen currently in conversation is the X screen. For example, when the operator inputs 2'' on the numeric keypad, the conversation processing system refers to the screen transition information table 83 of the X screen and determines whether the key input by the operator 21 matches the key input that triggers the screen transition. Decide whether or not.

In this case, in item number 2, T' is defined which means any numeric key input, and it can be seen that the operator's key input matches the key input that triggers the screen transition.

In other words, when the operator keys in "2",
In item number 2 of the screen transition information table 83 of the X screen,
It can be determined that the screen transition has been established and the screen ID of the transition destination is Z.

As a result of this screen transition establishment determination, display data is output with reference to the screen display information table 84 of the two screens that are the transition destination screens. At this time, the variables included in the display data are output by executing calculations in the variable/arithmetic expression information table and referring to the values in the same manner as in the sixth embodiment.

Note that the values of the input variables included in the arithmetic expressions in the variable/arithmetic expression information table 85 are assigned the values entered by the operator 21 using the numeric keypad.

For example, in the variable/arithmetic expression information table 85 on two screens,
The calculation formula of item number 2 includes an input variable (represented by T).

Since "2" keyed in by the operator 21 is assigned to this input variable, in the calculation of the variable/arithmetic expression information table 85 on the two screens, price is 300, quantity = T = 2, selling price = price x quantity = 300 x 2 =600 is obtained.

Furthermore, with reference to the calculation results of the variable/arithmetic expression information table 85 on the two screens, when all the display data in the screen display information table 84 on the two screens is output to the CR7 screen, the X screen (
CRT display screen 86) to 2 screens (CRT display screen 87)
) screen transition is completed.

[Effects of the Invention] According to the present invention, a control method for a conversation processing system can be formulated by repeating the same procedure, and specific processing contents can be realized without depending on called components.

Furthermore, the correspondence between definition data and calculation processing and conversation screens becomes clear, and it becomes obvious at a glance which screen the data and calculations affect, making it easier to design and change the specifications of the conversation processing system.
