Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an analog quantity setting device using a calculator and a keyboard with a graphic display.

[Technical background and problems of the invention]

Conventionally, analog quantities such as current and voltage values have been set using potentiometers, digital switches, and the like. In addition, with the recent development of computer systems, C
It is not uncommon to set analog quantities via a man-machine system using an RT or keyboard.

When setting an analog quantity using a potentiometer, the operator may be aware of the absolute quantity that corresponds to one meter value. For example, in a system that outputs a maximum current capacity of 1801 for a certain power supply with a maximum value of 10.0 on the meter, it is easy for an operator to set the meter to 5°O in order to obtain an output of 50 cm. but,
When the output of 1000 people is obtained, it is necessary to convert the meter value corresponding to that output.

In addition, when using a digital switch, the operator must
Although it is easy to set the absolute value as 0OA, since the limit values such as the power supply rating cannot be grasped, it is inevitable to set an unreasonable value. Also, when making adjustments during operation, the operator raises or lowers the volume slightly, but each digit on the digital switch indicates the proportion of the total volume. Difficult to understand.

Furthermore, when setting analog quantities via a man-machine system using a CRT and keyboard, the absolute quantities are usually set by inputting them from the keyboard, as with digital switches, but irrational input data is eliminated. In order to do this, input data is checked, and a settable range is displayed to improve operator operability.

In this way, there are a wide variety of conventional setting devices, including those that are effective for setting absolute amounts and those that are effective for setting percentages (for example, to indicate a slight increase or decrease). It is used depending on the purpose, but there are few that have both functions. However, the analog quantity setting should be easy to operate both when setting it as an absolute quantity and when setting it according to human senses during adjustment, and it should also be possible to set it within one system. However, if the setting means were to be different for each item, the operations for the operator would be complicated and it would be difficult to understand.

[Purpose of the invention]

The purpose of the present invention is to display analog quantities on a graphic nice play both as a graph and as an absolute quantity, and to make it possible to set absolute quantities as well as settings based on human senses with one simple key operation. The object of the present invention is to provide an analog quantity setting device that reduces operator input errors and improves operability and visibility by displaying limit values and the like on the graph.

[Summary of the Invention] To achieve the above object, the present invention provides a graph in which arbitrary analog quantities are specified on the X-axis and Y-axis, one set point indicating a set value on the graph, and Using a graphic display with a digital display that numerically displays the analog quantity specified for the axis and a keyboard with arrow keys that indicate up, down, left, and right, the operator can display the digital display while pressing each arrow key. By increasing/decreasing the set value and moving the set point in the direction of the arrow at the same time and ending the increase/decrease of the set value when the key is pressed, it is possible to differentiate settings based on absolute amounts and settings based on human sensation. The present invention aims to provide an analog quantity setting device that achieves both and improves operability for operators.

[Refreshing example of invention]

An embodiment of the analog quantity setting method using a graphic display and a keyboard according to the present invention will be described below.

FIG. 1 shows an example of a graphic display screen for setting the voltage and current values of a certain power source.

On the graphic display 12, the X axis 1 is current (A)
, the scale of voltage (v) is displayed on the X-axis 2.

3.4 corresponds to the maximum voltage and maximum current values, respectively, that is, the area surrounded by the line 1.2.5.6 is the settable area. 7 is a set point representing the current set values EV and IA, and the coordinates (X, Y) are displayed.

Current setting value 1. IA is the set price digital display section 8゜9
It is displayed as a single value. When the operator presses the date key 11 on the keyboard 13 indicating an increase in the X-axis direction,
The digital display 8 of the X-axis, that is, the voltage value, is increased by a small resolution △E specified in advance in the program, and at the same time the set point 7 on the graph shows a voltage of E + △E until the location coordinates (x, y) are reached. Moving. While the day key is pressed,
The increase in the digital display and the increase in the set point on the graph are repeated continuously, and the process ends when the operator releases the key. When this program is repeated n times, the set point 7 before the start of setting has moved to the set point 1o after the end of setting, which represents a voltage of E1nΔE.

FIG. 2 shows a functional diagram for realizing the auxiliary statement. The pressed key monitor 3 constantly monitors whether the key fob is pressed. When it is detected that a key has been pressed, the pressed key determining means 4 determines whether the setting end key is an arrow key or another key.

If it is any other key, the monitor function will continue without any exception. If an arrow key is detected, the set value increasing/decreasing means increases/decreases analog amounts designated for the X-axis and Y-axis in correspondence with each arrow key. At this time, the increase/decrease is defined in advance on the program as the minimum settable resolution of each analog quantity. Depending on the increase or decrease,
When a new analog quantity is calculated, the setting value digital display section display means 7 changes the numerical value of either the X-axis or the Y-axis, whichever is requested to be increased or decreased. At the same time, the graph coordinate calculation means 6 calculates X and Y coordinates from the analog quantity, and the graph set point display means 8 displays them at the new set position. Also, at this time, the previously displayed set point has been erased by the previous set point erasing means 9, and these processes are repeated.

FIG. 3 shows an example of a flowchart of a program that can realize the above functions.

With the above process, while the operator is pressing the arrow key,
You can see the set point moving in the direction of the arrow, and you can also see changes in the absolute amount at the same time. In other words, operations equivalent to slightly raising or lowering can be performed while watching the movement of the set point on the graph without knowing the absolute amount.If you want to set an arbitrary absolute amount, for example 100OV, you can use the digital display. You can set it while looking at it.

In addition, the frame of the graph indicates the settable range to prevent inexperienced operators from setting unreasonable values and increasing the number of operations unnecessarily.

FIG. 4 shows another embodiment, in which the analog quantity calculated by the set value increasing means 5 is checked by the set limit value checking means 1 to see if it exceeds the limit value. If the limit value is not exceeded, use the previous setting point clear function, XY
Prompts the coordinate calculation function, but does not prompt if the limit value is exceeded.

Then, the set value increase/decrease means 5 returns the previously set analog amount again, and continues monitoring the keyboard. As a result, for example, after the set point has been moved to the top of the graph frame in Figure 1, even if you keep pressing the arrow key, the set point will remain on the frame and will not move out. become. This is effective in reducing operational errors by operators, and is also effective when displaying a function graph or the like on a graph to indicate a limit value.

Furthermore, by adding diagonal arrow keys to the keyboard, it is also possible to simplify the operation of increasing and decreasing X and Y simultaneously.

〔Effect of the invention〕

As explained above, 1. According to the present invention, when an operator sets an analog quantity, the operator can be informed of the change in the absolute quantity and the positional relationship between the proportion of the total quantity and the limit value at the same time. This makes it possible to set absolute amounts and make small increases or decreases, such as adjustments, with simple operations using only the arrow keys. Furthermore, since the positional relationship with the limit value is always clearly indicated, unnecessary operational errors are eliminated and a setting method with clearly high operability is provided.
