Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a heart rate monitor.

[Background technology]

Recently, the number of obese people has been increasing due to improvements in eating habits, but this trend is not a positive one because obesity weakens resistance to various adult diseases.

Jogging and various sports are popular in order to prevent this, or to relieve the lack of exercise in daily life and actively maintain one's health. In that case, if a person who does not exercise much on a daily basis exercises suddenly, it may actually cause serious problems, so it is necessary to control the amount of exercise to an appropriate level. What happens is the change in heart rate (also called pulse rate) during exercise. In other words, remember your normal heart rate when you are not exercising, compare it with your heart rate during exercise, and control the amount of exercise you do so that your heart rate does not increase beyond a certain level. It is. In this way, you can avoid unnecessary overload exercise.
It is possible to prevent serious failures from occurring. In order to facilitate such control, various heart rate monitors (also called pulse needles) have been developed.

For example, there is a conventional heart rate monitor as shown in FIG. That is, a sensor 2 that is attached to a part of the human body 1 (such as a cardiac potential induction site or a blood pulse wave detection site) that detects a heartbeat, a calculation unit 13 that calculates and counts a heartbeat from its output waveform, and a heartbeat It shows the number and the setting value (
It is composed of an alarm device (such as a buzzer), a row display 14, etc., which is designed to issue an appropriate alarm if the amount of exercise exceeds the amount of exercise (which is a guideline for effective momentum). Since such a heart rate monitor can be handled like a wristwatch, it can be easily used for jogging, etc., and the user can easily control the amount of exercise using the alarm as an indicator. In the figure, 15 is a counter. Furthermore, as another function of such a heart rate monitor, an upper and lower limit of the heart rate can be set, and when this value is compared with the actually measured heart rate, an overload alarm is issued when the upper limit is exceeded. On the other hand, a device equipped with an upper/lower limit heart rate setter 16 and a comparator 17 has also been developed so that an exercise insufficient alarm is issued at the lower limit. That is,
As seen in the heart rate progress graph during exercise shown in Figure 8,
After setting an upper limit heart rate A and a lower limit heart rate B on the heart rate monitor in advance and starting exercise, if the measured heart rate is in the exercise insufficiency warning area a and the exercise overload warning area C, the alarm 14 This will cause a warning to be output from the system. By sensing this alarm, the user can appropriately control his/her own exercise amount, so that the user can always keep the heart rate within the optimum exercise range.

However, it is not always the case that you only need to exercise once in - days, so if you want to know the total amount of effective exercise for that day, or you can use the total amount of effective exercise done for each week or month as a guide. In some cases, you may want to control your own momentum. Conventional heart rate monitors have not been able to meet such demands because they have no means for accumulating the amount of exercise.

[Purpose of the invention]

In view of the above points, the present invention accumulates the time during which the user maintains a heart rate equal to or higher than a predetermined heart rate set according to the user's exercise goal, making it possible to easily know the total amount of effective exercise. The purpose is to provide a heart rate monitor.

[Disclosure of the invention]

In order to achieve the above object, the present invention includes a sensor that is attached to a part of the human body to detect the heartbeat, a calculation unit that counts the heart rate based on a signal emitted from the sensor, and an output display of the result of the calculation unit. In the heart rate monitor comprising an output display section, the calculation section compares a set heart rate set in advance and the measured heart rate, and accumulates the time during which a heart rate higher than the former is generated. The gist of the present invention is a heart rate monitor characterized by being provided with an accumulation means.

This will be explained in detail below with reference to the accompanying drawings.

FIG. 1 shows an example of a heart rate meter according to the present invention. This heart rate monitor consists of the following components. That is, a sensor 2 is attached to a wrist or the like corresponding to a so-called cardiac potential induction site or a blood pulse wave detection site in a human body 1 to detect a heartbeat, and the detected signal is inputted and calculated to obtain a desired output. It consists of a calculation section 3, an output display section 11 to which its output is sent, a heart rate setter 6 for setting a heart rate as a reference in advance, and a counter switch 12 for setting an initial value of a counter 10, which will be described later.

As the sensor 2, a photoelectric type sensor that electrically detects heartbeat is often used, but it is not particularly limited to this. The calculation unit 3 calculates the difference between the actually measured heart rate and the preset heart rate in synchronization with the counter 5 that calculates and counts the signal emitted from the sensor 2 and the end of counting by the counter 5. a subtracter 7 having a function, a clock pulse generator 8 that emits a pulse once at regular time intervals, and a subtracter 7.
A gate 9 that allows clock pulses to pass only when the measured heart rate is larger in the result of , and a counter 1 that accumulates (counts) the clock pulses output from this gate 9.
0, and its cumulative value is displayed on the output display section 11. The subtracter 7 receives input from a heart rate setter 6 that can set a heart rate as a guideline in advance. counter 10
A counter clear switch 12 for initializing the counter is connected as necessary.

If this counter clear switch 12 is provided,
This is convenient because the cumulative time in a desired period can be easily determined.

Next, the operation of the heart rate monitor according to the present invention will be explained with reference to FIGS. 2 and 3.

Figure 2 shows changes in heart rate over time when a person performs a certain amount of exercise. Here, D is a preset heart rate, and T1 to T4 represent the time when the heart rate during exercise exceeds D (the time during which the effective amount of exercise is maintained). Taking as an example the case where such exercise is performed, the operation of the heart rate monitor will be explained based on FIG. 3.

Before starting the exercise, operate the counter clear switch 12 to set the initial value to zero (G). A counter 5 receives the signal emitted from the sensor 2 and counts the heart rate. When heart rate counting is completed, a heart rate calculation completion signal (C) is sent to the subtractor 7. The subtracter 7 compares and subtracts the measured heart rate B and the set heart rate A in synchronization with this signal (C) (in other words, the subtracter 7 has a function of comparing the sizes), and based on this subtraction result, When the measured heart rate B becomes larger, an output signal (D=borrow output) is generated that allows the clock pulse (E) to pass through the gate 9. While this pollo output is occurring, a clock pulse passes through gate 9. That is, the clock pulse (E) being transmitted from the clock pulse generator 8 passes through the gate 9 and is sent to the counter 10 only during this output period. The counter 10 counts (H) the clock pulses that have passed through the gate 9 and outputs the result to the output display section 11 .

The output display section 11 displays the total amount of exercise, which is the cumulative total of clock pulses, in terms of time. The display method at this time is not limited to displaying the cumulative time as a digital value, but the configuration of the calculation section described above is an analog circuit, and heart rate settings, calculations, etc. are processed analogously, and the result is may be displayed in analog form.

In this manner, the counter 10 counts only the time during which the heart rate exceeding the set heart rate is maintained among the actually measured heart rates, so the user can easily know the total amount of effective exercise.

Furthermore, the heart rate monitor according to the present invention may be provided with a heart rate setting device 19 as shown in FIG. That is, this heart rate setting device 19 includes a keyboard 20 that can input an arbitrary heart rate, and a keyboard controller 21 that converts the input heart rate into a predetermined signal. The signal is latched by the latch section 22. This is convenient because the set heart rate can be easily changed at any time.

In addition to the one shown in FIG. 4, as shown in FIG. 5, there is a heart rate setting device 23 that allows you to input your age and exercise load and set a predetermined heart rate by taking these into account. It may be provided. In other words, as shown in Figure 6, it is known that there is a certain relationship between heart rate at the maximum load (100%) that a person can exercise and age. You can check the relationship between load amount and heart rate according to your current needs. Figure (a) shows the relationship between age and heart rate at the maximum load (100%);
C1 shows a similar relationship for 60% and 50% loads, for example.

This relationship is shown in Table 1 using data (HR
II...HRnn) and set this to heart rate setting device 2.
When the user inputs his or her age and target load amount via the keyboard 20, the heart rate output device 24 detects the heart rate. By calculating the number and outputting it to the latch section 22, the set heart rate (HRnn) can be obtained.If such a heart rate monitor is used, it will be easier to ensure the amount of exercise according to one's own physical strength. Extremely convenient.

Table 1 [Effects of the Invention] Since the heart rate monitor according to the present invention has the above-described configuration, it is possible for the user to easily set an exercise goal for any desired period of time, and also to measure the cumulative amount of exercise during that period. It's easy to know, and it's easier to manage your own exercise goals.
Extremely convenient.

Moreover, since it becomes easy to set goals according to one's own physical strength, it can be used by a wide range of age groups.
