That is, the mode register M has M = “0”.
Is the time display mode, the year of the clock register 31,
The current time data of month, day, hour, minute, second are sent to the display register 30 and displayed on the display device 5. When the push button K1 is operated in this time display mode, the value of the mode register M is incremented by 1 to M = “1”, and the mode is switched to the physical strength measurement mode. The operation and display in this physical strength measurement mode will be described later.

In the time display mode, the push button K
When 2 is operated, the value of the mode register M is incremented by 2 to M = “2”, and when the push button K2 is operated in the physical fitness measurement mode, the value of the mode register M is incremented by 1 and M = It becomes "2" and the setting mode is set.

When the push button K2 is operated in this setting mode, the value of the mode register M is decremented by 1 and M = “1”, and the mode is switched to the physical strength measuring mode.

Next, FIGS. 5 and 6 show a processing program of a flow chart in the physical strength measuring mode. In this example, the stepping up and down exercises are performed twice at different paces (pitch) for 3 minutes each with a 20 second time interval (rest time), and the pulse at the end of each exercise is measured. Thus, the maximum exercise load and the appropriate exercise load of the person to be measured are obtained in the physical strength measurement mode.

Therefore, in the ROM 2, the maximum heart rate determined according to the age of the person to be measured and the appropriate heart rate corresponding to a predetermined percentage (here, 65%) of the maximum heart rate are associated with each other. Have table data stored. The appropriate heart rate refers to a heart rate during moderate exercise that allows the subject to perform exercise to a certain extent without shortness of breath, and can be used for physical fitness training for endurance.

Then, when the time display mode is switched to the physical fitness measuring mode, or when the setting mode is switched to the physical fitness measuring mode, the flow of FIG. 5 is started.

Step A1 is a process of storing pitch data of two exercises in the registers S1 and S2 based on the age data stored in the age register 32. That is, as shown in the table below, the ROM 2 prestores the pitch data per minute to be stored in the registers S1 and S2 corresponding to the age, and the pitch data is read and stored in the registers S1 and S2 of the RAM3. Let

Register S1 Register S2 Age 13 to 29 years 90 110 Age 30 to 39 years 80 100 Age 40 to 79 years 70 90 For example, when the age is in the range of 13 to 29 years 90 pitches per minute for the first lifting movement
Is stored in the register S1, and the pitch 110 per minute of the second lifting motion is stored in the register S2.

As is clear from the above table, the pitch is faster in the second time than in the first time, which is stronger in the second time than in the first time. It shows that it is exercise.

In the next step A2, the timer register T2 for 20 seconds is cleared and then the timer operation is started. Then, in the next step A3, the pulse detection circuit 9
Is detected to detect the presence / absence of a pulse signal, and if there is a pulse signal, the pulse per minute is calculated from the detected pulse signal, stored in the register P0, and displayed on the display device 5. That is, at this time, the person to be measured can measure and display the pulse before exercise by putting his / her finger on the light emitting diode 24 and the phototransistor 25. Therefore, even if the user wants to know the pulse at an arbitrary time regardless of the exercise for measuring the physical strength, the pulse can be measured and displayed by touching the finger at this time.

After measuring the pulse in step A3, or if no pulse signal is detected, the process proceeds to step A4, and it is determined whether or not the value of the timer register T2 is up, that is, whether 20 seconds have elapsed. When 20 seconds have not passed since the timer operation was detected, the steps A3 and A4 are repeated.

Next, when 20 seconds have elapsed, the process proceeds from step A4 to step A5 in FIG. In step A5, the alarm unit 10 causes the alarm unit 10 to generate an alarm sound for starting the stepping up / down motion. Then, in step A6, it is determined whether or not the value of the number-of-times storage register N is N = “0”. At this point in time, N = “0”, so the process proceeds to step A7.

In step A7, the pitch alarm sound based on the pitch sound data of the first motion stored in the register S1 is started. This warning sound is made by the warning sound unit 10 with a different sound (for example, different frequency, different volume, etc.) from the above-mentioned warning sound for starting the stepping up / down motion of step A5, and will be described later. Step A
3 until the sound is stopped by the pitch sound stop processing at 11
Done for a minute.

That is, in the next step A8, the 3-minute timer register T1 is cleared and the 3-minute timer operation is started.

Then, in the next step A9, it is detected whether or not the timer register T1 has timed out, that is, whether or not 3 minutes have elapsed from the start, and when it has not elapsed, the time is up in step A10. The remaining time of the display is displayed on the display device 5, and thereafter steps A9 and A1 are performed.
Repeat 0.

When three minutes have passed, the pitch sound stop processing is performed in step A11 to stop the alarm sound. Therefore,
The person to be measured moves up and down in the step S5 in accordance with the pitch sound of the pitch stored in the register S1 for 3 minutes after the sound of the step A5 for starting the step-up / down movement is issued, and the first exercise ends. To do.

When the pitch sound is stopped in step A11, the next 20-second timer T2 is cleared and started again in step A12. And the next step A
At 13, the pulse is detected, and the detected pulse data is stored in either of the registers P1 and P2.

In this case, which of the registers P1 and P2 is to store the measured pulse data depends on the value of the register N, and is measured when N = “0”, that is, immediately after the first exercise. The pulse is stored in the register P1, and the pulse measured when N = “1”, that is, immediately after the second exercise, is stored in the register P2. Since N = “0” at this point, the measured pulse data is stored in the register P1.

When the pulse is measured and stored in step A13, it is determined in next step A14 whether or not the 20-second timer T2 has timed out, and the pulse measured in step A15 is kept until 20 seconds have elapsed. indicate. This 20
The second is a predetermined rest time for the person to be measured.

When 20 seconds have elapsed, the process proceeds to step A16, the value of the register N is incremented by 1, and the process returns to step A5. At step A5, a warning sound is made to start the stepping up / down motion,
In the next step A6, it is determined whether N = “0”. At this time, N = “0” is not set, but the value of the register N is incremented by 1 in step A16 and becomes N = “1”, so the process proceeds to step A17.

In step A17, if N = "1" is determined, the process proceeds to step A18. In step 18, as in step A7, pitch sound is started. In this case, the point different from step A7 is that the pitch sound corresponding to the pitch data stored in the register S1 in step A7 is different from that in step A18.
That is, the pitch sound corresponding to the pitch data stored in is started.

When the pitch sound is started in step A18, the process returns to step A8 described above, and the processes from step A9 to A15 are performed. That is, a pitch sound is output for 3 minutes, and then a rest time of 20 seconds is reached. During that time, since the pulse data measured in step A13 is N = “1”, 2 is stored in the register P2.
The pulse data corresponding to the second exercise is stored.

When 20 seconds have passed, step A1
In step 6, the register N is incremented by 1 and N = “2” is set to step A.
Return to 5. In step A5, a sound is made to start the stepping up and down, but since the exercise has already been completed twice, no pitch sound is generated thereafter, and this sound functions as a sound to end the measurement. . That is, after step A5, since N = “2”, steps A6 and A17
And the value of the register N is N =
It is changed to "0". Then, in the next step A20, it is determined whether or not the measured pulse data or the like has an error.

The error detection in this step A20 is 4
It detects two errors. The first is register 3
This is the case where the weight, sex, height of the table, etc. are not included in 3, 34, 35, respectively, or even if they are included, extremely abnormal values different from normal values are entered.

The second case is that the pulse data is not stored in the registers P1 and P2, that is, the pulse measurement cannot be performed normally.

The third is a case where the stored pulse is extremely abnormally high or low even though the stored pulse is stored.

The fourth case is that the magnitude relation of the stored pulse data is abnormal. That is, register P
0, P1, P2 of the pulse stored in the register P0
The pulse stored in the register is the pulse before exercise and must be the smallest, and the pulse stored in each of the registers P1 and P2 is the pulse when the exercise load is increased by increasing the pitch. The pulse of the register P2 should be higher than the pulse of P1.
Therefore, when the pulse stored in the registers P0, P1 and P2 does not have such a relationship, it is processed as an error.

The data indicating the kind of error detected in step A20 is stored in the register E, and the display showing the content is displayed on the display unit in the next step A21, for example, "second measurement error". Is displayed in.
Then, a process of returning to the time display mode after a lapse of a predetermined time, for example, 1 minute, that is, the value of the register M is set to "0"
Is processed.

However, when the error is the second error and the pulse is not stored in any of the registers P1 and P2, after the above display, the value of the register N is changed to the corresponding value. Then, the flow is executed again from step A5. This makes it possible to execute the exercise again from the exercise in which the pulse is not stored.

If no error is detected in step A20, the process proceeds to step A22, the calculation of the physical strength is performed, and the calculation result is displayed on the display device 5 in step A23.

FIG. 7 is a flow chart showing a subroutine of calculation processing in step A22 of FIG. 6, and FIG. 8 is a flow chart showing a subroutine of pitch sound generation processing of proper exercise load in step A23 of FIG. 9 is a diagram showing the principle of calculation of physical fitness measurement, and FIG. 10 is a predicted pitch diagram showing the relationship between exercise pitch and heart rate.

Therefore, referring to the principle diagram of FIG.
8 will be described, and the pitch sound generation process of FIG. 8 will be described with reference to the predicted pitch diagram of FIG.

First, as shown in FIG. 9, the vertical axis (Y) indicates the heart rate and the horizontal axis (X) indicates the exercise load.
t). In the present embodiment, the amount of work W obtained when the exercise is performed twice, that is, when the stepping up / down movement is performed at the respective pitches stored in the registers S1 and S2, is obtained by the following formula.

W = weight (Kg) × 9.8 × height of table (m) × pitch ÷ (4 × 60) Here, the coefficient of 9.8 is the gravitational acceleration in consideration of the step-up / down movement. Yes, the unit is m / s · s. The unit of the pitch is steps / minute, and the stepping up and down is 1 in 4 steps.
Since this is a cycle exercise, the number of times one lifting / lowering cycle is performed per second is calculated by pitch / (4 × 60).

When the amount of work obtained in the first exercise is W1 and the pulse measured corresponding to the exercise, that is, the heart rate data stored in the register P1 is HR1 (see FIG. 7). Step A100), point B0 in FIG.
Is obtained.

Next, the work amount W obtained in the second exercise is W2, which is measured corresponding to the exercise and is registered in the register P.
When the heart rate data stored in 2 is HR2 (Fig. 7
Step A101) of FIG. 9, and a point B1 is obtained in FIG. Then, from the coordinate data of the points B0 and B1, Y = a
A predicted load line indicated by X + b is obtained (step A102 in FIG. 7).

Next, the maximum heart rate HRmax for that age is determined from the age of the subject. Generally, 220-age is said to be the maximum heart rate, and this may be used, but in this embodiment, HRmax (male) = 209−0.69 × age HRmax (female) = 205 for each gender. -0.75 x age is used. This is a calculation formula obtained by measuring the movements of many people. The maximum heart rate of the person to be measured can be sequentially obtained by using the above-described calculation formula, but the results calculated for all ages are stored in the ROM 2 in advance, and the measured heart rate input from the key input unit 12 is stored. The maximum heart rate corresponding to the age of the person may be read out. This maximum heart rate (HRmax) is HR4 in FIG. Then, the value of the maximum heart rate HR4 (HRmax) in FIG.
= AX + b is inserted in Y, and the maximum exercise load, which is the value of X (work load W4), is obtained (step A103 in FIG. 7). This maximum exercise load (W4) is a limit exercise load for the person to be measured, and if the exercise load of this level is continuously applied, shortness of breath will occur and a dangerous pulse rate will be required.

Next, a heart rate of 65% of this maximum heart rate (65% HRmax) is calculated, and the heart rate is set as an appropriate heart rate of the subject. This proper heart rate can be calculated by setting 65% of the maximum heart rate,
In the present embodiment, a table in which the proper heart rate is stored in advance corresponding to each maximum heart rate is formed in the ROM 2, and the desired proper heart rate is obtained only by inputting the age and sex of the subject or the maximum heart rate. May be understood. If this appropriate heart rate is HR3 in FIG. 7, this value is inserted into Y of Y = aX + b, and the value of X (workload W

Further, in this embodiment, the registers S1 and S2 are
Although the predicted load line (Y = aX + b) was obtained from the predetermined amount of exercise according to the first and second exercise pitches stored in the table and the heart rate measured during this exercise, three or more exercises with different amounts of exercise were performed. The heartbeat rate may be calculated by using the result, and the predicted load line may be calculated based on the result. In that case, a more accurate predicted load line can be obtained.

Furthermore, in the above embodiment, the appropriate heart rate was calculated as 65% of the maximum heart rate or stored in the ROM, but the present invention is not limited to this, and the maximum heart rate of 60% may be stored depending on the situation. % Or 70%, or other%
You can also use to set an appropriate heart rate.
