Description

Detailed Description of the Invention <Technical Field of the Invention> The present invention includes a heart rate detection means for detecting the heart rate of a user, and measures the amount of exercise of the user based on the heart rate detected by the heart rate detection means. The present invention relates to an exercise management device that performs exercise management.

<Prior art> In conventional exercise management devices of this kind, the heart rate detection sensor used as the heart rate detection means includes one that uses an optical sensor to monitor blood flow, and one that uses electrodes to monitor electrocardiograms. In the latter case, blood flow itself is greatly affected by the movement of the body during exercise that involves large body movements such as jogging, and measurement during exercise is considered impossible; Although measurements can be taken even during exercise, each method has its drawbacks, such as the need to attach electrodes to bare skin, making it less convenient.

As mentioned above, it is difficult to efficiently measure heart rate during exercise, but within a certain range of purposes, it is not necessary to monitor heart rate throughout exercise in driving management. It is. In other words, how much exercise did you get by doing a certain exercise, for example jogging?
If you want to know how effective the effect is, you can at least roughly calculate it from the heart rate immediately after jogging and the time you jogged, but if it is calculated only from the heart rate immediately after jogging, The disadvantage is that the error is large because changes during the process are completely ignored.

<Object of the Invention> The present invention has been made in view of the above points, and an object of the present invention is to obtain an exercise management device that can efficiently measure heart rate with less error and accurately manage exercise.

<Embodiments of the Invention> An embodiment of the exercise management device of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of the usage state of the exercise management device of the present invention, where 1 is a heart rate sensor which is attached to the user's earlobe and sends the user's heart rate signal to the main body 2 of the exercise management device of the present invention. . 3 is a belt that fixes the main body 2 to the user's body.

FIG. 2 is a schematic configuration explanatory diagram of the main body of the exercise management device of the present invention, and 5 is a vibration detection sensor provided in the main body 2 to detect vibrations of the user, for example, a spring and weight called a pedometer. It uses the inertia of the oscillator to derive an electrical signal, that is, a vibration signal.
Reference numeral 6 denotes a clock section for timekeeping, which may be a commercially available clock section which is generally known as a real-time clock IC and is designed to be connected to a microcomputer. Numeral 7 is a key switch for the user to set each operation, and has a start key, an end key, etc. 8
is comprehensively controlled based on the heart rate signal from the heart rate sensor 1, the vibration signal from the vibration detection sensor 5, the clock signal from the time clock section 6, and the key signal from the key switch 7, and provides predetermined data for exercise management. This is a general control unit that prints out the information using the printer 9, for example.

The general control section 8 is composed of a microcomputer as shown in FIG. 3, and each external signal is exchanged through an I/O section 93. In Figure 3, 80 is the CPU, 81 is the ROM, 82
is a RAM, and 84 is a timer.

Next, the operation of the exercise management apparatus of the present invention constructed as described above will be explained with reference to the flowchart shown in FIG.

When the start key of the key switch 7 is pressed, the comprehensive control section (microcomputer) 8 measures the heart rate. Since various methods and configurations of this heart rate measurement are known, their explanation will be omitted, but for example, the cycle of pulse input may be measured by the integrated control unit 8.
Period measurement is performed using a counter and timer 84 set in RAM 82 in general control section 8. The number of nights per night data calculated in this way is stored in the RAM 82 as a pair of data with a time value that is set to 0 at the time or when the start key is pressed. Here, the time or time value is the clock part 6.

When you start jogging like this,
The vibration detection sensor 5 generates pulses according to the movement of the user's body, and the comprehensive control unit 8 determines that the user is not stationary based on the fact that the pulses are continuously input. Then a predetermined period of time (e.g. 2 seconds)
When the pulse from the vibration detection sensor 5 stops, it is determined that the device is in a stationary state. This stationary state occurs when you stop at a stop signal or take a short break while jogging. However, since it is not always necessary to know the heart rate continuously, in order to make effective use of the memory, the heart rate is measured here only when a predetermined time (for example, one minute) has elapsed since the previous heart rate measurement.

After repeating the above operations, the heart rate and time or time data at a predetermined point in the resting state until the key switch 7's off key is pressed are stored in the RAM 8.
2, and when the off key is pressed, the 5th
The heart rate data 10 as shown in the figure is printed on the printer 9.
It will be printed and output.

It goes without saying that the data stored in the RAM 82 can be used not only as a printout but also as data for checking cardiopulmonary function and training.

As described above, the vibrations of the user's body are detected and the heart rate is measured when the user is in a resting state, so there is no possibility of taking false data, and the continuous measurement as shown in Figure 6 is possible. Since the heart rate can be measured without much difference, a simple and efficient exercise management device can be provided.

<Effects of the Invention> Since the exercise management device of the present invention measures the heart rate when the person is in a stationary state, the measurement is not much different from that when the heart rate is measured intermittently and continuously. In addition to this, there is also less error in heart rate measurement, and it is simpler than the case where data is taken continuously, yet it allows for accurate exercise management.

Furthermore, the storage capacity for storing the above data can be reduced, and the storage means can be used effectively.
