BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data setting device for a control device in industrial equipment.

[0002]

2. Description of the Related Art Conventionally, a control device for digitally controlling industrial equipment using a microcomputer or the like is provided with a setting device for inputting data necessary for digital control. Conventional setting devices of this type generally use a number key from 0 to 9, that is, a so-called numeric keypad, and a so-called up / down key for increasing / decreasing a set value with two types of up / down keys.
Two schemes using the down key have been widely used.

[0003] However, in the case of the ten-key system, ten switches are required only by the numeric keys, occupying a large area of the setting panel, making it difficult to miniaturize the apparatus, and having a large number of parts, cost, and reliability. There was a problem in terms of gender.

In the case of the up / down key system, the number of switches is at least two, one for up and one for down.
However, when the range of the value of the setting data is wide, that is, when the value of the setting data covers a large number of digits, the movement amount of the data is large. That is, when changing from a very small value to a large value, or from a large value to a small value, the operation time is long and the speed is poor.

[0005] In order to solve this problem, an up / down key is provided for each digit of the set value to improve operability.
A method of providing two types of low-speed keys is conceivable,
Then, the number of switches inevitably increases, and the same problem as in the case of the ten-key system occurs.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems. Specific technical means include a variable setting device, an A / D converter for converting an output of the variable setting device into a digital value, and a current setting value in a data setting device of a control device for industrial equipment. A control device comprising: a display to be displayed; and a unit that reads a rotation speed and a rotation direction of the variable resistor, performs a predetermined calculation, stores the calculation result, and outputs the result to the display.

Even if the variable resistor is reversed immediately afterwards, the operation result is retained.
In addition, the calculation is continued by continuing to rotate at high speed in the forward direction.
And increased .

FIG. 1 is a schematic view of a setting panel showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a setting panel of the control device. Numeral 2 is a dial-type variable resistor, which has a finite rotation angle of one rotation or less. 3 is a display. Reference numeral 4 denotes a switch of the storage device. Reference numeral 5 denotes an item selection switch for selecting a required control element from a plurality of items. Reference numeral 6 denotes an item display lamp corresponding to the selected item.

FIG. 2 is an example of the configuration of an electric block circuit diagram using a variable resistor. In this figure, 1 to 6 are the same as those in FIG. Reference numeral 7 denotes an A / D converter for converting the output of the variable resistor 2 into a digital signal. Reference numeral 8 denotes a microcomputer which stores the item number designated by the item selection switch 5 through the input port 9 and outputs the data to the item display lamp 6 via the output port 10 to display the data and to rotate the variable resistor. The speed and rotation direction are read to perform a predetermined calculation, and the result is displayed on the display 3 via the display drive circuit 11.

When data is input to the setting device, when the variable resistor 3 is operated by a dial, the rotation speed and the rotation direction are read by the micro computer 8 via the A / D converter, and FIG. High speed rotation from A to B as shown in (a)
When it is moved to, the value displayed on the display changes at high speed as shown in the display data in the figure. Also, when moving from the same A to B at low speed rotation as shown in FIG. 4B, the numerical value displayed on the display changes to low speed. That is, the microcomputer detects a change in the rotation speed when the dial is turned quickly and when the dial is turned slowly, and when the dial is turned rightward quickly, the data value is increased at a high speed, and when the dial is turned leftward, the dial is turned leftward. When it is turned quickly in the direction, it operates to reduce the data numerical value at high speed.

In this case, the change speed of the display 3 is not proportional to the rotation speed of the variable resistor 2, but is made to be sharper, for example, proportional to the square, so that a large value change can be performed by the variable resistor 2. By rotating the data instantaneously to the target value by the high-speed rotation of 2, and then turning slowly after approaching the target value, reliable fine adjustment setting can be performed for each digit.

If the variable resistor 2 requires a large value change, it may not be possible to achieve the single-rotation type. In order to cope with this, the present invention is configured to ignore the high-speed reverse rotation immediately after the high-speed rotation that is equal to or higher than a certain value. For example,
Rotate the dial clockwise to the limit of rotation to increase the value, and then rotate the dial in the opposite direction (left), the increased data does not decrease. -Further increase the data. That is,
Even if the rotation angle range of the variable resistor 2 is within one rotation, the dial is held and the high-speed forward / reverse rotation is repeated within the rotation movement range, during which the high-speed change in the rotation direction initially turned is maintained in one direction Thus, a large value change is possible.
After confirming that the displayed value has reached the target value, the storage switch 4 is pressed to store the data in the microcomputer 8.

Next, the embodiment of FIG. 3 is an example of a configuration of an electric block circuit diagram when an infinitely rotating encoder 12 is used instead of the variable resistor. In this case, the operation is the same as in the case of using a variable resistor, except that the function of ignoring reverse rotation immediately after high-speed rotation of a certain speed or more is omitted.

[0014]

As described above, according to the setting device of the present invention, the rotation speed and the rotation direction of the variable resistor are read by the microcomputer, and the contents of the display are determined according to the rotation speed and the rotation direction. When increasing or decreasing the value , a large value change or a small value change may occur within one rotation of the dial of the variable resistor.
The rotation angle can be set easily, quickly and accurately by high-speed forward / reverse rotation . As a result, operability is improved, and reliability is improved and the cost is reduced by reducing the number of components. In addition, the setting device of the present invention can be applied to a control device for other uses to expand operability of input setting.
