DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display for automatically changing a display range according to a data value and displaying data.
The present invention relates to a control device and a data display control method .

[0002]

2. Description of the Related Art Conventionally, there are known wristwatches having sensors for measuring atmospheric pressure, temperature, etc., and wristwatches for measuring lap time, which display and notify measured sample data stored in a memory. The method of displaying these data is to display the data as it is digitally or as a graph.

[0003]

Generally, when data is displayed in a graph form, there is an advantage that continuous changes in data can be recognized at a glance. However, if all data having a wide range of values are displayed on a display screen of a limited size such as a wristwatch, it is necessary to increase the scale of the display. The range of values represented by individual pieces must be increased. For this reason, there is a drawback that even if the data slightly changes, the data is displayed in the same manner as the previous data, the display does not change, and a subtle change in the data cannot be displayed.

[0004] Further, if the scale of the display is made fine in order to change the display in response to a subtle change in the data, when the data to be newly displayed changes greatly, the display becomes the upper limit (or lower limit) of the display range. There is a problem that the user jumps out and cannot know how different the data is compared with other data.

An object of the present invention, data can be displayed by setting the always appropriate display range within the bounded display screen data
It is an object to provide a display control device and a data display control method .

[0006]

The means of the present invention are as follows. In the data display control device according to the first aspect, first, a plurality of data are simultaneously obtained along the column direction in the order in which the data are obtained.
And the old data column every time new data is imported
The position in the direction is shifted by one column and displayed.

Next, the display upper limit changing means enlarges or reduces the upper limit of the display range according to the value of the newly fetched data. The means comprises, for example, a microprocessor or the like.

[0008] In the data display control device according to the second aspect,
In addition to the display control means and the display upper limit changing means, the display range changing means predicts a tendency of data to be taken next time based on a predetermined number of latest data every time new data is taken, and based on the predicted tendency. The upper and lower limits of the display range are changed. The means comprises, for example, a microprocessor or the like.

In the data display control device according to the third aspect,
In addition to the display control means , the range enlarging means and the range changing means, when the data being displayed does not fall within the range of the current display, the display of the position corresponding to the data is blinked to notify the user. The means comprises, for example, a display drive circuit or the like.

[0010]

The operation of the means of the present invention is as follows. In the data display control device according to the first aspect of the invention, every time new data is taken in, old data is moved by one column and displayed, and the upper limit of the display scale is expanded according to the value of the newly taken data. Or reduced. Thus, new data can always be read at an appropriate display position.

A data display control device according to a second aspect of the present invention.
In addition to the above operation, the tendency of data to be taken in next time is predicted every time new data is taken, and the upper and lower limits of the display range are changed based on the prediction.
Thus, the tendency of data to change can be easily recognized.

A data display control device according to a third aspect of the present invention.

Thus, when new data is displayed at an appropriate position, the presence of other old data located outside the display screen can be easily known.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an external view of a wristwatch according to one embodiment of the present invention.

Referring to FIG. 1, a wristwatch 11 includes a liquid crystal segment display device, which is provided on substantially the entire upper surface thereof and is described later, and includes a graph display unit 12 for displaying measured data in a graph, It is provided horizontally below the section 12 and is about one-fourth the size of the graph display section 12, and is composed of six 7-segment displays and two colon displays, for displaying time in seconds. And a time display unit 13. The watch 11 has a preset, sampling time setting,
It has three push-button switches 14a, 14b and 14c for instructing the start / stop of measurement and the like. Bands for wearing on the wrist are provided on the side of the 12 o'clock side and the 6 o'clock side. 15 are mounted respectively.

FIG. 2 is a block diagram of the internal circuit of the wristwatch 11. In FIG. 2, an oscillating circuit 21 generates a clock signal having a fixed period, and divides the clock signal into a frequency dividing circuit 2.
Output to 2.

The frequency dividing circuit 22 divides a clock signal input from the oscillating circuit 21 by a predetermined period to obtain a frequency of 1 Hz (Hertz).
, And outputs the clock signal to one input terminal of the control unit 20 and the AND gate circuit 24.

The control unit 20 comprises a microprocessor or the like, and controls the entire system based on a program stored in a fixed memory (not shown). Further, a time measurement process is performed based on a clock signal input from the frequency dividing circuit 22, and the current time data is stored in a clock register 32 of the RAM 29 described later. Further, the control unit 20 includes three push-button switches 14a, 1 shown in FIG.
When a preset is instructed by a key operation signal input from 4b or 14c, when a start of altitude data measurement is instructed, or when sampling timing is reached by a timing signal input from a timer 25 described later, the signal a is output. Then, the A / D conversion circuit 27 and the atmospheric pressure / altitude calculation circuit 28 described later are started. When the start of the altitude data measurement is instructed, the signal b
Is output to the set terminal of the flip-flop 23 and the reset terminal of the timer 25, which will also be described later. Further, when the stop of the altitude data measurement is instructed by the key operation signal, the signal c is output to the reset terminal of the flip-flop 23.

The flip-flop 23 is set at its set terminal by a signal b applied from the control unit 20, and activates a signal Q output to the other input terminal of the AND gate circuit. In addition, the reset terminal is reset by a signal c applied from the control unit 20, and the signal Q is made inactive.

When the signal Q from the flip-flop 23 applied to the other input terminal is active, the AND gate circuit 24 sends the clock signal from the frequency dividing circuit 22 applied to one input terminal to the timer 25. The clock signal is cut off when the signal Q becomes inactive.

The timer 25 is, for example, a subtraction timer.
The measurement time set by the key input to the push button type switch 14b is reset by a signal b applied from the control unit 20,
The value is set to "0" every time the set time is counted by performing the subtraction by the clock signal input from the AND gate circuit 24, and the timing signal is output to the control unit 20 to be reset again. The counting process is stopped by stopping the input of the clock signal.

The pressure sensor 26 comprises a semiconductor strain gauge or the like, detects an air pressure, generates an analog voltage signal proportional to the detected air pressure, and outputs the generated analog voltage signal to the A / D conversion circuit 27. .

The A / D conversion circuit 27 converts the analog voltage signal output from the pressure sensor 26 into a digital signal, and outputs the converted digital signal to the atmospheric pressure / altitude calculation circuit 28.

An atmospheric pressure / altitude calculation circuit 28 performs a predetermined calculation based on the digital signal input from the A / D conversion circuit 27, calculates altitude data corresponding to the digital signal, and controls the calculated altitude data. The control unit 20 outputs the altitude data input from the atmospheric pressure / altitude calculation circuit 28 to a predetermined register of the RAM 29 as described later.

The RAM 29 is a random access memory and, as shown in FIG. 3, described later, is constituted by registers for storing predetermined data. The display drive circuit 30 decodes a combination of signals input from the control unit 20 and outputs a display drive signal to the display device 31.

The display device 31 has a graph display unit 2 and a time display unit 3 composed of the liquid crystal display device shown in FIG. 1, and based on a signal input from the display drive circuit 30, the graph display unit 2 Alternatively, a predetermined display is performed on the time display unit 3.

FIG. 3 is an external view of the graph display unit 12 of FIG. In the figure, there are 30 graph display units 12 in the vertical direction and 8 in the horizontal direction.
And a total of 240 segment display bodies 12-1, and one bar graph display is formed by the 30 segment display bodies 12-1 arranged in the vertical direction. Eight bar graph display surfaces are configured as a whole in eight rows. At the left end of the eight bar graph display surfaces,
At its upper end, an upper limit scale display section 12-2 composed of four 7-segment displays, a central scale display section 12-3 also composed of four 7-segment displays at the center,
Further, a lower limit scale display section 12-4, which also includes four 7-segment display bodies, is provided at the lower end.

Next, FIG. 4 shows an internal configuration diagram of the RAM 29 shown in FIG. In the figure, a register 41 stores clock data (current time data) generated based on a clock signal output from the frequency dividing circuit 22.

The register 42 stores upper and lower limit data indicating the display scale (data displayed on the upper limit scale display section 12-2 and the lower limit scale display section 12-4 shown in FIG. 3).

The measurement data area 43 has eight registers 4
3-1 to 43-8, each of which has a sampling
Altitude data measured based on barometric pressure at each immersion
D₁, D _Two... D₈Is stored. And the latest data
Each time is measured, the altitude data D measured up to the previous time
₁~ D₇Are sequentially transferred to the registers 43-2 to 43-8.
Altitude data D_Two~ D₈As the latest measurement data
Data is altitude data D₁Stored in register 43-1
Is done.

The display data area 44 also has eight registers 4
Consists of 4-1～44-8 are respectively calculated based on the eight altitude data D ₁ stored in the register 43-1～43-8 of, D ₂ · · · D ₈ of the measurement region 43 The display data 1 to the display data 8 are stored which include the lighting number data of the segment display body 12-1 and flag data indicating an overflow (or underflow).

The scale area 45 stores a scale table in which the display range of the altitude data is set in steps of 100 m (meter). The work area 46 temporarily stores intermediate data and the like during calculation at the time of calculation.

Next, the display in the two kinds of display modes of the wristwatch 11 having the above configuration, that is, the display upper limit changing mode and the display range changing mode will be described. First,
FIGS. 5A, 5B, 5C, and 5D show examples of display in the display upper limit change mode.

FIG. 3A shows that the display scale has a lower limit of 0 m, an upper limit of 100 m, and a median of 50 m. Therefore, the data increment of one segment display body 12-1 is set to 3.3 m. Altitude data h based on
-1, h-2, ..., h-7, h-8 are displayed in a graph.

FIG. 6B shows a display when the altitude data h-9 measured next after the above becomes 113 m. (a) Since the display cannot be performed with the upper limit of the display scale of 100 m, the upper limit is changed to 200 m to expand the display range, and the data increment of one segment display body 12-1 is set to 6.6 m. Measurement data h-9 is displayed at the right end of the screen. Since the old data h-1, h-2,..., H-7, h-8 have each moved left by one column, the data h-1 disappears off the screen and h-2.
~ H-8 are displayed on the enlarged display scale (the visual display is reduced).

FIG. 3C shows that the upper limit of the display scale is 200.
m (the data increment of one segment display unit 12-1 is 6.6 m), and the altitude data h-7 and h-8 are displayed near the upper limit.

FIG. 3D shows a display when the altitude data h-9 measured next after the above becomes 83 m. Since this altitude is 100 m or less, the upper limit of the display scale is 100 m.
m, the display range is reduced (the data increment of one segment display body 12-1 is 3.3 m), and the new measurement data h-9 is displayed at the right end of the screen. Also in this case, the old data h-1 disappears, and the data h-2 to h-8 move one column to the left and are displayed on the reduced display scale. And
Since the data h-7 and h-8 are higher than the upper limit 100 m of the reduced display scale, the data display protrudes above the screen.
-7, h-8 at the top of the display position
7 'and h-8' are blinking.

As described above, in the display upper limit changing mode, the upper limit of the display scale is changed so that the latest measured data always falls within the display screen, and the display range is enlarged or reduced.

Next, FIGS. 6A to 6I show examples of display in the display range change mode. Also in this case, the old data display sequentially moves to the left, and the oldest data display disappears.

FIG. 7A shows that the median of the display scale is 20.
0 m, the lower limit is 185 m and the upper limit is 215 m. Therefore, the display range width is 30 m, and one segment display body 12-1 corresponds to a data increment of 1 m. The data h-1 (186 m) and h-2 (187
m)... h-8 (203 m) are displayed.

FIG. 7B is based on the assumption that the altitude data h-9 measured next is 214 m, which is displayed on the display scale shown in FIG. From the change in the altitude data, an altitude of 231 m is predicted in the next measurement, and the difference from the minimum value h-2 of 187 m is 44 m, which cannot be displayed with the current display range width of 30 m. Therefore, it is necessary to increase the display range width of the display scale. For this reason, the display of (b) is canceled, and the median of the display scale is changed to 209 m, the lower limit is changed to 179 m, and the upper limit is changed to 239 m, as shown in FIG.
Is set to 2 m to expand the display range width to 60 m and display.

FIG. 4D shows that the median of the display scale is 50.
0 m, the lower limit changes to 470, and the upper limit changes to 530, the display range width is 60 m, and the data increment of one segment display body 12-1 is 2 m. And
This is an example of a case where all measurement data changes near an altitude of 500 m.

FIG. 11E shows that the altitude data h-9 measured next to the above becomes 500 m similarly to the previous measured value, and
It is assumed that the image is displayed with the display scale of (d). From this change in altitude data, 49
The lowest value of 8m is predicted and the highest values h-5 and h-6 are 5
The difference from 04m is 6m. This change amount is one tenth of the current display range width of 60 m, and the state of the change may not be read well. Therefore, the display of (e) was canceled and the median of the display scale was changed to 5 as shown in (f) of the same figure.
01m, the lower limit is changed to 486m, and the upper limit is changed to 516m to reduce the display range width to 30m.
By setting the data increment represented by 2-1 to 1 m, the display is performed so that even a small change amount can be displayed large. Therefore, the highest values h-5, h
-6 is also displayed separately in 503m and 504m.

Next, in FIG. 9G, the median of the display scale is 285 m, the upper limit is 330 m, and the lower limit is 240 m. The display range is 90 m, and one segment display 12-1 is shown. The data increment is 3 m. In this example, the latest several data fluctuate around 300 m.

FIG. 7H shows a case where the altitude data h-9 (290 m) measured next is displayed on the display scale of FIG. From the change of this altitude data, the next measurement value is expected to be 280m and the highest value h-8
Is 320 m, which is 40 m. In such a case, the display of (h) is canceled because the state of the change may not be well read, and the median of the display scale is 300 m, the upper limit is 330 m, and the lower limit is 270 m, as shown in FIG.
And the display range width is reduced to 60 m, and the data increment represented by one segment display body 12-1 is set to 2 m so that a large change amount can be displayed, and display is performed. Also, since h-2 of the previous display data is lower than the lower limit and does not appear on the display surface, the segment display body h-2 'at the lower end of this display position is flashed.

Next, the operation of the embodiment having the above configuration will be described with reference to FIG.
This will be described with reference to flowcharts in FIGS. 9 (a) and 9 (b). FIG. 7 is a flowchart of a process in the display upper limit changing mode, and FIG. 8 is a flowchart of a process in the display range changing mode. In these processes, it is assumed that the sampling interval is set in advance by key input of the push-button switch 14b.

In the processing in the display upper limit changing mode shown in FIG. 7, the control unit 20 first performs an initialization processing in step S1. Thereby, all the segment display bodies 12-1 of the graph display unit 12 are turned off, the display is erased, and the RAM is turned off.
The 29 registers 42, measurement data area 43, display data area 44, work area 46, etc. are cleared to "0".

Then, the process proceeds to a step S2, wherein it is determined whether or not a timing signal is output from the timer 25, and if not, this determination is repeated. Thus, data measurement does not start until the next data measurement timing.

If it is determined in step S2 that the timing signal is output from the timer 25, the process proceeds to step S3, where the signal a
Is output to activate the A / D conversion circuit 27 and the atmospheric pressure / altitude calculation circuit 28, thereby converting the atmospheric pressure data detected by the pressure sensor 26 into altitude data and taking it in. Thus, every time the set time elapses, the altitude is measured and the altitude data is taken.

Subsequently, the flow advances to step S4 to perform a shift process described later in detail. As a result, RA
The old altitude data in the measurement data area 43 of M29 is sequentially moved down, and the new altitude data is stored at the top.

Next, in step S5, a scale search process, which will be described in detail later, is performed. Thereby, the upper limit value (S _MAX ) of the scale corresponding to the newly measured altitude data is detected.

In step S6, an increment dh (= S _MAX ÷ 30) of the altitude data represented by one segment display 12-1 on the scale set based on the detected upper limit value S _MAX is calculated. .

Then, the process proceeds to a step S7, where the RAM 29
Altitude data D _{1 to} D ₈ stored in the measurement data area 43 of FIG.
Is read out, converted into display data 1 to 8, respectively, and stored in the RAM 29.
Are stored in the registers 44-1 to 44-8 of the display data area 44. As a result, display data (data indicating the number of lighting of the segment display body 12-1) corresponding to the altitude data is stored in the RAM 29. These display data 1 to 8 are obtained by the following formulas.

H _Dn = D _n ÷ dh where n = 1 to 8 H _Dn = display data 1 to 8 D _n = altitude data D _{1 to} D ₈ .

Next, the process proceeds to step S8, in which the display data 1 to 8 are sequentially read from the RAM 29, and it is determined whether or not any of the data exceeds the upper limit or falls below the lower limit of the set scale. If there is any, the flag data indicating this is added to the display data, and the data is stored again in the registers 44-1 to 44-7 or 44-8 of the display data area 44 of the RAM 29 from which the data has been read.

Subsequently, in step S9, the RAM 2
9, the display data 1 to 8 are read out, a display drive signal is created based on the display data 1 to 8, and output to the display drive circuit 30. Thereby, for example, FIGS. 5 (a), (b),
As shown in (c) and (d), a graph is displayed on the display device 31.

Then, in step S10, start /
It is determined whether or not a key input of the stop key (push button type switch 14c) has been made. If no key input has been made, the process returns to step S2 to wait for an output from the timer 25 again. As a result, if there is no key input of the start / stop key, the measurement of the altitude data is continued at each sampling timing.

When the key input by the start / stop key is detected in the step S10, the processing is terminated. Next, the processing of the shift process in step S4 will be further described with reference to the flowchart of FIG. In this process, although not particularly shown, the control unit 2
A built-in register n is used for 0.

First, in step S21, "8" is set in the register n. Subsequently, in step S22,
After confirming that the value of the register n is not “1”, the process proceeds to step S 24, and the measurement data area 43
From the register 43-i (i = n-1)
_n-1 is read and the read altitude data D _n-1 is stored in the register 43-n of the measurement data area 43.
Stored as Then, the process proceeds to step S25, where the register n is decremented by "1" and the above-described step S22 is performed.
And the steps S22 to S25 are repeated. As a result, the old altitude data D _n-1 (n = 2 to 8) in the measurement data area 43 of the RAM 29 is sequentially moved to the lower position.

"1" repeated at step S25
If it is detected in step S22 that the value of the register n has become “1” by the decrement, step S23
The process proceeds, the altitude data fetched in step S3 (see FIG. 7), and stores the data D ₁ in the register 43-1 of the measurement region 43. As a result, the acquired new altitude data is stored at the top of the measurement data area 43.

Next, the processing of the scale search process in step S5 (see FIG. 7) will be further described with reference to the flowchart shown in FIG. 9 (b). First, step S
In 31 sequentially searches the upper data of the scale table of the scale areas 45 of RAM29 from the lower, the process proceeds to step S32, the upper limit data to determine whether or not the newly acquired altitude data D ₁ or more, D If it is ₁ or more, it is determined that the scale having the upper limit data is an appropriate scale, the scale data is fetched, and the process ends. The upper limit value of this scale data is used as _SMAX described above.

If the upper limit data is smaller in step S31, the process returns to step S31 and returns to step S3.
1. Repeat S32. Thus, the scale area 45
Are sequentially searched from the bottom.

Next, the processing in the display range change mode will be described with reference to the flowchart shown in FIG.
The processing from step S11 to step S14 in FIG.
Steps S1 to S1 in the display upper limit change mode, respectively.
The processing exactly the same as the processing of S4 (see FIG. 7) is performed.

Next, in step S15, a new altitude data D _1, reads the altitude data D _2, and altitude data D ₃ of the second last of the previous, details expected value of altitude data will be described later next (D _NEXT) Is calculated, and an altitude data increment dh newly set for each segment display unit 12-1 is calculated from the expected value D _NEXT .

Then, the process proceeds to step S16, which will be described later in detail, and calculates the predicted value D _NEXT and the maximum value (D _MAX ) or the minimum value (D _MAX ) of the data currently displayed.
_MIN ) and the center value of the new scale (S _CENT )
_Is calculated, and the upper limit (S _MAX ) and the lower limit (S _MIN ) of the new scale are calculated from the center value S _CENT and the height data increment dh calculated in step S15. Then, based on the calculated data, the altitude data Dn (n
= 1 to 8) are converted into display data 1 to 8 and stored in the registers 44-1 to 44-8 of the display data area 44.

The processing in the following steps S17 to S19 is also performed in step S17 in the display upper limit changing mode.
The processing is performed in the same manner as the processing of 8 to S10 (see FIG. 7). As a result, the next altitude data is predicted by the latest three altitude data D _{1 to} D ₃ , a scale suitable for the predicted altitude data is set, and the current display data is, for example, shown in FIG. It is displayed as shown in (f) and (i).

Here, for reference, each data stored in the measurement data area 43 and the work area 46 of the RAM 29 corresponding to the display shown in FIGS. 6 (c), (f) and (i) is shown in FIG. . D _NEXT , increment, center, upper limit, and lower limit shown at the bottom of the figure are the expected value D _NEXT of the next measurement altitude data, the increment dh of the altitude data in the new scale, and the scale Central value S
_{CENT is} the upper limit S _MAX and lower limit S _MIN of the scale. The altitude data D _{1 to} D ₈ shown in the upper part of FIG.
This corresponds to the graph displays h-9 to h-2 described in FIGS. 6 (c), (f), and (i).

Next, steps S15 and S16 described above are performed.
In the following, an algorithm for calculating the expected value D _NEXT , increment dh, center value S _CENT , upper limit S _MAX and lower limit S _MIN will be described.

The expected value D _NEXT is the latest value of the altitude data
₁ , the previous data is D ₂ , and the data before last is D ₃
“D _NEXT = D ₁ + ((D ₁ −D ₃ ) − (D ₁ −D ₂ ))
+ (D ₁ −D ₂ ) ”. Here, ((D ₁
−D ₃ ) − (D ₁ −D ₂ )) is the data growth rate, (D ₁
−D ₂ ) is the increment this time.

The increment dh is defined as D _MAX and D _{MIN as} the maximum value and the minimum value of the currently displayed data, respectively, and calculates the calculated expected value D _NEXT and the number of one segment graph 12-1 in one graph. since the 30 ", when the expected value D _NEXT is higher than the current value D ₁ is" _{dh = (D NEXT -D MIN)} ÷ 30 ", when the expected value D _NEXT is lower than the current value D ₁ is" dh = (D _{MA X}
−D _NEXT ) ÷ 30 ”.

When the expected value D _NEXT is higher than the current value D ₁ , the center value S _CENT is calculated as “S _CENT = (D _NEXT +
D _MIN) ÷ 2 ", when the expected value D _NEXT is lower than the current value D ₁ is obtained from each" _{S CE NT = (D NEXT +} D MAX) ÷ 2 ".

The upper limit S _MAX is expressed as “S _MAX = S _CENT +
dh × 15 ”, and the lower limit S _MIN is
It is determined from “S _MIN = S _CENT −dh × 15”. The conversion from the altitude data D _n to the display data n (n = 1 to 8) is calculated from “display data n = (D _n −S _MIN ) ÷ dh” based on the data obtained above.

In the above embodiment, the pressure data is taken in by the pressure sensor, and the taken-in pressure data is converted into altitude data and displayed. However, the display data is not limited to the altitude and may be the pressure itself. , Also pressure,
Humidity, temperature, lap time and the like may be used. In addition, although the segment display 12-1 at the upper end or the lower end of the graph position is blinked for display data outside the display screen, a separate display may be provided instead of blinking. Further, the conversion formula from the altitude data to the display data and the calculation method of the upper and lower limit data of the display screen are not limited to those described in the above embodiment.

Although a semiconductor strain gauge is used for the pressure sensor, a metal strain gauge, a differential transformer,
An indirect type pressure sensor such as a capacitance type may be used.
It may be a direct type pressure sensor such as a piezoelectric element.

[0074]

According to the present invention, each time new data is fetched, the position of the old data in the column direction is moved by one column and displayed.
Since the upper limit of the display scale is enlarged or reduced according to the value of the newly acquired data, new data can always be read at an appropriate display position.

Further, each time new data is fetched, the tendency of the next fetched data is predicted, and the upper limit and the lower limit of the display range are changed based on the prediction, so that the tendency of the data to change is easily recognized. be able to.

When there is data that does not fit in the current display range of the display screen, the corresponding display is notified by flashing. When new data is displayed at an appropriate position, other data located outside the display screen are displayed. Can easily know the existence of old data.
