- step S9 The principle of the running motion pitch detection operation executed in step S9 This will be briefly described.
- the body motion signal in the body motion detection unit 104 is superimposed with (i) an acceleration signal associated with the vertical movement and (ii) an acceleration signal associated with the swing of the arm.
- the acceleration associated with vertical movement appears equally when the left foot is stepped on and when the left foot is stepped, so one cycle of the acceleration signal associated with the vertical movement is It is considered to be equivalent to one step in running exercise.
- the pendulum motion pulls back the left hand from the front when the left foot is stepped out, and descends the left hand from the back when the right foot is stepped.
- the acceleration signal is synchronized with the acceleration signal accompanying the vertical movement, and that one cycle is equal to two steps in the running motion. For this reason, in the body motion signal in which the acceleration component of the vertical motion and the arm swing motion is superimposed, the first harmonic component is due to the vertical motion, and the second harmonic component is the arm swing motion. It is thought to be due to.
- the pitch in the running motion can be detected, for example, by the CPU 201 processing the body motion signal from the body motion detection unit 104 as follows. That is, first, the CPU 201 performs the FFT processing on the body motion signal in the body motion detection unit 104, and second, the harmonic component having the largest peak is determined as the second harmonic component.

- step Sa6 the CP controller 201 determines whether a linear relationship is established between them. At this time, it may be considered that the exercise intensity and the beat rate include some errors. If the linear relationship is established, the running motion is performed before the appearance of the mutation point Hlltp, and satisfies the application condition in the nomogram of Astrand-Ryhmmg.

- the upper / lower limit value setting unit 21 shown in FIG. 17 performs the processing described in “Basic Configuration and Operation” to obtain the pulse rate. Find the upper limit UL and lower limit LL of.
- the user wears the finger belt 15 shown in FIG. 16 on his / her finger, and starts running at the time shown in FIG. 27, for example.
- the pulse Z pitch detector 22 shown in FIG. 17 detects the pulse and the pitch of the user by performing the processing described in “(2) Pulse nobiti detector” earlier, and calculates the values.
- a pulse detection signal BS and a pitch detection signal PS are output.
- the upper / lower limit comparing section 23 compares the pulse detection signal B S with the upper limit value UL and the lower limit value LL, and outputs a signal SS corresponding to the comparison result.
- the initial pitch setting unit 33 (see FIG. 18) does not output the signal Sa, and the control unit 34 does not set the initial pitch. Therefore, the pitch control signal PCS is not generated, and the sound emitting section 25 does not generate the pitch sound.
- pulse rate indicated by pulse detection signal BS exceeds lower limit value LL.
- the signal SS output from the upper / lower limit comparing section 23 indicates “exceeding the lower limit value”, and the initial pitch setting section 33 (see FIG. 18) outputs the signal Sa.
- the control section 34 takes in the user's pitch indicated by the pitch detection signal PS, sets this as an initial pitch, and outputs a pitch control signal PCS corresponding to this pitch.
- the sound output section 25 generates the pitch sound at the pitch corresponding to the pitch control signal PCS (in this case, the current user's pitch, and in the example shown in FIG. 27, 160 steps / minute). appear. That is, when the user's pulse exceeds the lower limit LL, a pitch sound is generated for the first time, and the sound emission interval is equal to the user's pitch at that time.
- PCS the pitch control signal
- the stop control section 35 sends the control section 34 a command.
- the pitch control signal PCS is stopped, and the pitch sound of the sound output section 25 is stopped. Accordingly, sound of the pitch sound at sound emitting part 2 5 is performed by the time from the time t 2 shown in FIG 7.
- the reason that the pitch sound is cut off after the lapse of the time Ti is that the user's pitch after entering a steady running state is generally stable, and is almost constant even if there is no indication of pitch sound etc. This is to save power consumption because unnecessary pitch instructions are not given because the vehicle runs at the same pitch.
- the pulse of the user was traveling at the initial pitch, soars as shown in FIG. 2 7, it exceeds the upper limit UL at time t 3, the output signal SS of the upper and lower limit comparison unit 2 3 This indicates “exceeding the upper limit value”, and the control unit 34 (see FIG. 18) controls the pitch control signal PC so that the pitch drops at a predetermined rate until the user's pulse falls below the upper limit value UL.
- the control unit 34 when changing the pitch, the control unit 34 outputs the pitch control signal PCS again, and causes the sound emitting unit 25 to output a pitch sound. This is because the user needs to be aware of the pitch change. Then, at time t, the user's pulse falls below the upper limit UL, and the control unit 34 stops adjusting the pitch control signal PCS. Therefore, the set pitch of the control unit 34 is fixed to the pitch immediately before the time (145 steps / minute). When the changed pitch and the user's pitch match for a predetermined time, this is detected by the stop control unit 35, and the pitch control signal PCS is stopped again.
- the stop control unit 35 causes the control unit 34 to output the pitch control signal PCS.
- the sound output section 25 outputs the pitch sound again, and the user changes his / her own running pitch according to the pitch sound.
- the generation of the pitch control signal PCS is stopped by the stop control section 35.
- the pulse of the user is reduced gradually, for example, at time t 6, when drops below the lower limit LL, the output signal SS of the upper and lower limit comparison unit 2 3 will denote the following lower limit value, the control unit 3 Step 4 adjusts the pitch control signal PCS so that the pitch increases at a predetermined rate until the user's pulse exceeds the lower limit LL.
- the control unit 34 when changing the pitch, the control unit 34 outputs the pitch control signal PCS again, and causes the sound emitting unit 25 to output a pitch sound.
- pulse rate there is a slight time lag until the time t 7 the adjustment is started pitch control signal PCS from a time that falls below the lower limit LL, which is the control unit 3 4 monitors signal SS at predetermined intervals and because doing, in this example, the timing t 7 the monitoring is carried out is delayed from the time t 6 by the short evening Imi ring.
- the pitch instruction to the user has a sufficiently fast cycle.
- the pitch sound generated at the time 7 is stopped after the elapse of the time T i, which is controlled by the stop control unit 35 as in the above-described case.
