Description

TECHNICAL FIELD The present invention relates to a command and control device, and more specifically to a command and control device used in office equipment such as copying machines and office computers, and educational equipment.

A conventional command control device controls the execution of an execution device according to commands input from an input device and the state of equipment according to rule data stored in a storage device. In other words, it determines whether an event such as a command or device status input from an input device matches the rules stored in the storage device, searches for a rule that can be applied to the event, and uses this rule to control the input/output device or Controls the execution unit.

However, conventionally, the rule data stored in the storage device is fixed, so when performing complex control, the control algorithm becomes complex, and the same operation is always performed.
Flexible control that changes the control method depending on the situation has been difficult.

Furthermore, in a control method that searches for rules to be applied in response to data that changes due to events, the contents of the rules are fixed, so all data must be referenced at all times, which is inefficient. Another drawback is that when the number of rules increases, it becomes difficult to determine inconsistencies between the rules.

As described above, in conventional control devices, it is not possible to flexibly change the command state in response to operational inputs or changes in the state of the execution device, and it is particularly difficult to make corrections when the execution device is changed.

OBJECTS It is an object of the present invention to eliminate the drawbacks of the prior art and to provide a command control device that can perform efficient control with a small number of command operations using a simple control algorithm.

Configuration In order to achieve the above object, the present invention includes a detection means for detecting the state of the device, an input means for inputting an operation command, a display means for displaying an explanation for inputting the operation command, and an explanation display. In addition to storing input control data, it also stores change data that changes depending on the state of the equipment detected by the detection means and the operation command inputted by the input means,
Furthermore, there is a storage means for storing rule data for controlling the equipment, the input means, and the display means according to the change data, and a storage means for storing rule data for controlling the equipment, the input means, and the display means according to the change data, and a storage means for storing rule data for controlling the equipment, the input means, and the display means according to the state of the equipment detected by the detection means and the operation command inputted by the input means. and a control means for searching the rule data stored in the storage means for rules that can be applied according to the stored change data, and controlling the equipment, the input means, and the display means according to the rules, and the rules are used to control and operate the equipment. It is characterized by the fact that it includes things that can change over time. Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 shows a system to which an embodiment of the command control device of the present invention is applied. The command control device of the present invention includes an input/output device 2, a control device 4, and a storage device 6, and is connected to an execution device 8 made up of various devices.

As shown in FIG. 2, the input/output device 2 has an explanation display screen 20, which is an output device, on which an explanation display, for example, "Please press the button" is displayed. The input/output device 2 also has an input operation command switch 22 for inputting an operation command and an explanation display 24 corresponding to the long operation switch.

The command displayed on the explanation display 24 is input using the input operation switch 22 .

The control device 4 is connected to the input/output device 2, and the storage wave N6 and the execution device 8 are connected to the control device 4, respectively. The control device 4 retrieves data stored in the storage device 6 and executes a predetermined procedure based on the input of a command from the input/output device 2 or the signal indicating the status from the execution device 8. Show description.

The storage device 6 stores a database of fixed rules, variable rules, operation input control data, fixed rule execution data, variable rule execution data, explanation display data, and the like.

An example of the explanation display data is shown in FIG. 3(a). In this example, "Please press the button" is stored as data for the explanation display screen, and as a result, "Please press the button" is displayed on the explanation display screen.

An example of a fixed rule is shown in FIG. 3(b). In this example, for example, if an event occurs in the condition part (IF part) that says "the state of the execution device becomes an error state",
The execution unit (THEN unit) executes an execution process of ``saving the explanation display screen data and displaying an error on the explanation display screen''. In addition, when an event such as "the state of the execution device recovers from an error state" occurs, "Set the saved explanation display screen data and
An execution process of "clearing 0" is executed.

An example of fixed rule execution data is shown in FIG. 3(c). Fixed rule execution data stores variable names and their values. In this example, for example, the value corresponding to the variable name "execution device status" is "normally operating", which indicates that the execution device is operating normally. If an error occurs in the execution device, the variable name is ``Execution device status.''
The value corresponding to is changed to, for example, "error state".

Also, in this example, the value corresponding to the variable name "input key" is r
bJ, which indicates that the key input from the input operation command switch 22 is rbJ.

An example of a variable rule is shown in FIG. 3(d). In this example, for example, if an event such as "the input count of input capo button a becomes 5" occurs in the condition part (CIF part), that is, if a of the input operation command switch 22 is pressed five times, the execution part ( THEN section) "R button will not work even if you press it any more 1 will be displayed on the explanation display screen"
The execution process is executed.

An example of the variable rule execution data is shown in FIG. 3(e). The variable rule execution data stores variable names and their values in the same way as the fixed rule execution data. In this example, for example, the value corresponding to the variable name "input capo button a input count" is "5", which means that the input count of input capo button a, that is, the number of times a of the input operation command switch 22 was pressed is 5. It shows that.

As shown in FIG. 3(f), the operation input control data refers to the button name of the input operation command switch 22 of the input/output device 2, the explanatory text displayed on the explanation display screen 24 corresponding to the button, and the procedure. A pointer is stored. In this example, for example, when button a of the input operation command switch 22 is pressed, a message "Selection l designation" is displayed on the explanation display screen 24, and the execution device 8 executes procedure 1. Further, when button b is pressed, "r HELP command" is displayed on the explanation display screen 24, and procedure 2 is executed by the execution device 8.

A variable rule is a fixed rule or a variable rule execution part (T
The contents are rewritten by the execution processing of the HEN section) or the processing of procedures 1, 2, etc. of the operation input control data. Further, the contents of the operation input control data and explanation display data are rewritten depending on the input from the input operation command switch 22 and the state of the execution device 8.

The operation of this device will be explained with reference to the flowchart shown in FIG.

First, the control device 4 stores the data stored in the storage device 8 in FIG. 3 (a).
) to (f) are initialized (100). Next, an explanation is displayed on the explanation display screen 20 of the input/output device 2 based on the explanation display data, for example, "Please press the button" (102).

The control device 4 waits for an event to occur, and when the event occurs, the control device 4 sets the contents of the event to a variable indicating the event in the data stored in the storage device 8 (104).

For example, if the state of the execution device 8 becomes an error state, the variable name of the fixed rule execution data is "execution device status".
Set the value to change from "normal operation" to "error state" as shown in FIG.

In addition, if the key input from the input operation command switch 22 of the input/output device 2 is "a", the value of the variable name "input key" of the fixed rule execution data is changed from rbJ in FIG. 3(c). Set it to change to "a". Also, if the a button of the input operation command switch 22 of the input/output device 2 is pressed five times, the value of the variable name "count of input capotan a" in the variable rule execution data is set to be changed to "5". do.

The control device 4 examines the contents of the database stored in the storage device 6, searches for a rule among the fixed rules that satisfies the condition of the value of the variable currently stored in the fixed rule execution data, and satisfies the condition. It is determined whether there is a fixed rule (10B). If there is a fixed rule that satisfies the condition, the execution part (T
HEN section) is executed by the execution device 8 (10B
).

For example, if the variable name "execution device status" of the fixed rule execution data is "error state", the fixed rule rlf execution device status = error state. THEN
Since the condition part (CIF part) "Save the explanation display screen data and display an error on the explanation display screen" is satisfied, the execution part (THEN part) of this rule is executed. After the execution part is executed, the process returns to step 102 and an explanation display is displayed on the explanation display screen 20 of the input/output device 2 again based on the explanation display data.

If there is no fixed rule that satisfies the conditions, the control device 4
examines the contents of the database stored in the storage device 8, searches for rules that satisfy the variable values currently stored in the variable rule execution data among variable rules, and finds variable rules that satisfy the conditions. It is determined whether there is one (110). If there is a variable rule that satisfies the condition, execute part (THEN part) of the variable rule that satisfies the condition.
The procedure is executed by the execution device 8 (112).

For example, the variable name of variable rule execution data is
If the variable rule rCount of IF input capotan a = 5 7HENrIf the button is pressed any further, it will not work.1 will be displayed on the explanation display screen. ), the execution part (THEN part) of this rule is executed. After the execution part is executed, the process returns to step 102 and an explanation display is displayed on the explanation display screen 20 of the input/output device 2 again based on the explanation display data.

If there is no variable rule that satisfies the conditions, the control device 4
examines the contents of the operation input control data stored in the storage device 6, searches for a procedure that satisfies the conditions, and determines whether there is a procedure that satisfies the conditions (110). If there is a procedure that satisfies the conditions, it is executed by the execution device 8 (liB). For example, when button a "selection 1 command" is pressed, procedure l is executed.

A procedure that satisfies the conditions of the operation input control data, for example, procedure 1, first rewrites the operation input control data and the explanation display data (122), as an example is shown in FIG. As a result, the explanation display screen 2 of the input/output device 2
The data indicating the explanation displayed at 0 changes to the content according to the following situation, and each button a of the input operation command switch 22
The data indicating the display on the explanation display screen 24 corresponding to -d also changes to the content according to the next situation. Next, the variable rule is rewritten according to the current situation (124), and then an execution command is sent to the execution device 8 (1213).

Returning to FIG. 4, after the procedure is executed in step 11B, the process returns to step 102, and the rewritten operation input control data and explanation display data are used to display the explanation display screen 20 of the input/output device M2 and the input operation command. A new explanation display is displayed on the explanation display screen 24 corresponding to each button a to d of the switch 22.

According to this embodiment, by rewriting the operation input control data and the explanation display data, the next command to be input is displayed and the explanation control procedure is performed, and the variable name and explanation display data of the fixed rule execution data are The variable names of the variable rule execution data are changed depending on the situation, and the execution device 8 is controlled by rules that satisfy these variable names. Therefore, even when performing complex control, the control algorithm does not become complicated unlike conventional control using fixed procedures.

Further, according to this embodiment, since the variable rule is rewritten in the procedure corresponding to the operation input, the variable rule is always rewritten with content that can accurately respond to the next operation input or change in the state of the execution device. Therefore, since the variable rule always has contents that correspond to changes in the state, control can be performed using the variable rule by referring to the data for executing the variable rule.

Conventional devices perform control through operations as shown in FIG. 6 or 7.

In the example shown in Figure 6, initial settings are made (200), the system waits for an event to occur, and when an event occurs, the event content is set to a variable indicating the event (202), and display and control are performed according to the event content. (204)
. By not repeating steps 202 and 204 multiple times, control is performed using a fixed procedure.

Further, in the example of FIG. 7, initial settings are performed (300), and an explanation display is displayed on the explanation display screen of the input/output device based on the explanation display data (302). Wait for an event to occur, and when an event occurs, set the event content to a variable that indicates the event (304), search for a fixed rule that satisfies the variable values currently stored in the fixed rule execution data as a condition, and It is determined whether there is a fixed rule that satisfies (3013).

If there is a fixed rule that satisfies the condition, the execution unit 8 executes the procedure of the execution unit (THEN unit) of the fixed rule that satisfies the condition (308). After the execution part is executed, the process returns to step 102, and an explanation display is displayed on the explanation display screen of the input/output device again based on the explanation display data. If there is no fixed rule that satisfies the condition, the process returns to step 304, waits for an event to occur, and when an event occurs, sets the event content to a variable indicating the event.

Conventionally, rules were fixed in this way, so when controlling by referring to execution data, all data had to be referenced at all times.

Therefore, it was inefficient, and when there were a large number of rules, it was difficult to determine inconsistencies between the rules.

According to this embodiment, since the variable rules have contents that correspond to state changes, there is no need to perform control using a large number of rules, and therefore there is no need to refer to many unnecessary rules, resulting in efficient control. This enables efficient control with a small number of operation command switches 22.

Furthermore, since the contents of the variable rules can be added, deleted, etc., the control method and explanation method can be easily changed.

According to this embodiment, since the command state can be changed flexibly, accurate control can be performed even when the execution device is changed.

Effects According to the present invention, rules for controlling devices, input means, etc. are stored in the storage means, and the rules include those that can be changed. Control can be performed efficiently with a small number of commands. Furthermore, it is easy to change the control method and explanation method, and can also be applied to changing the execution device.
