Description

heart rate monitor

technical field

The invention relates to a heart rate tachometer with audio output.

Background technique

Traditional heart rate monitors usually have a chest strap to detect continuous heartbeats, and a watch-shaped display from which the measured heart rate can be read at the time. Communication between the chest strap and the display is accomplished by suitable wireless communication transmissions, such as radio frequency signals. It is also possible to connect by wires, but this hinders the user's freedom of movement, so it is not ideal. Monitors are typically worn on the wrist and attached to the handlebars of a bicycle or exercise machine.

There are many different heart rate monitors, but a common defect of these products is that the user can only read the results from the display. We know that reading values on a watch-sized display can be difficult when the user is engaged in high-intensity activities, due to the impact of sweating and fatigue on human vision. In addition, if the display is fixed at a certain position, it is of course difficult for the user who is exercising to read the displayed results due to the distance. Users can also choose to wear the display on the wrist, such as wearing a watch, but even then, the display needs to be moved into their line of sight, which will break the movement rhythm; and the wrist relative to the head when exercising in relative motion.

Another difficulty lies in reading the value of the display, especially at this time when the user will be tired, so it is necessary to concentrate on reading the value, which may lead to an accident or collision if the user is running or cycling. Therefore, a heart rate monitor without an audio output can be said to be somewhat dangerous.

There is a need for a heart rate prompting method that overcomes the above disadvantages and can maintain the user's ideal exercise rhythm.

Contents of the invention

The heart rate tachometer proposed in the present invention includes a device for detecting the beating of the heart and continuously sending out the heart rate signal, and a processor for converting the above signal into audio output at fixed intervals.

In order to ensure the measurement results, pulse and pulse rate are introduced in this measurement technique as a reference for heartbeat and heart rate.

The processor is preferably separated from the detection means so that the processor can be placed in a convenient location, for example somewhere on the garment. The communication between the detection device and the processor can be transmitted through radio frequency, but in order to ensure the accuracy of signal transmission, it is better to realize the communication through wire connection.

A radio, music player and/or visual display device may be incorporated into the processor. It is also possible to incorporate a real-time clock in the processor.

Processors can contain a built-in speaker and/or output for earbuds or headphones.

The most suitable way to embody a heartbeat detector is a chest strap, although it has been observed that a pulse detector can also provide an adequate signal for a wrist-mounted heartbeat tachometer.

Additional features of the invention can be seen from the description of several inventive examples, which are illustrated as follows:

Description of drawings

Figure 1: shows the first embodiment of the present invention;

Figure 2: shows a second embodiment of the present invention;

Figure 3: shows a third embodiment of the invention.

Detailed ways

In FIG. 1, the chest strap 11 contains a heart rate monitor. The processor is connected to the chest strap through a wire 13 and a plug 14, and a display screen 15 and a speaker 16 are also included in the figure.

In use, useful information such as elapsed time is provided in the display, and a built-in processor for converting heartbeats into audible audio output is included in the invention. Therefore, a timing clock is also included in the processor, and the measured consecutive heartbeats are compared with the timing of the clock, thereby generating an audible audio output using next-generation speech technology. Thus, the output of the heart rate meter may contain continuous electrical pulses which are compared with the timing pulses of the timer to form a beats per second (bpm) signal. Generally, the processor contains a memory, and a viewing platform is installed inside, and a predetermined sounding audio output is generated according to the bpm signal, or a signal is generated by several partial audio parts.

In this way, the user can obtain the audible audio output information without interrupting the rhythm of the movement or turning the gaze to the display screen. A volume/tone controller can be added as needed.

In the example of FIG. 1, the processor 12 is connected by wires that can be clipped to a convenient location, such as the back strap of an undershirt. Another option is to place the processor in a chest strap, in which case a wired speaker is used, which can also be placed in the chest strap.

The processor may also contain the usual ancillary functions found in conventional heartbeat tachometers, including, for example, some or all of the following:

1. Real-time function

-Year, day of the week, month, purpose, hour, minute, second.

- Choose to use 12/24 hour timing.

In these functions, references to 'laps' refer to the repetitive portion of a movement state, measured in terms of distance, time or number of repetitions. The 'stroke' mentioned in the function also refers to the complete course of motion measured in distance, time or repetitions. A 'trip' usually consists of multiple turns.

The above-mentioned functions can be selectively input by using the conventional buttons 17, 18, 19 shown in Fig. 1, and then displayed according to the needs of the user.

The audio output through the speaker allows multiple sounds or voice messages to be delivered to the user, also selected/activated by the above three buttons. If all the above functions are provided, some buttons can be added.

The display can display a variety of functions so that the user can review, for example, the total time spent exercising to determine their own performance or simply check the time. After exercising, audio information is issued according to the displayed functions, and sports performance can be reviewed. For example, the maximum heart rate can be displayed and reported by audio at the same time.

The audio output can be repeated according to the user's ideal time interval, and the user can also properly operate the buttons 17, 18, 19 to change the time interval according to his own wishes.

Another unique feature of the present invention is that it can give an audible signal of whether the user is or is not in an 'active state'. In this way, when the user is exercising according to the predetermined progress, the user will be encouraged to speed up, suggested to slow down or reminded that the user has reached an appropriate pace through sound information. In addition, if the user's exercise method is unreasonable, such as maintaining an excessively high heart rate for a long time, a sound signal will also be generated to report to the user.

A second embodiment of the present invention is shown in FIG. 2 , comprising a chest strap 21 and a watch device 22 , which includes a display screen 23 and a speaker 24 . The functions of the watch device are the same as those described above with respect to the processor 12, and the data is transmitted wirelessly, for example by radio frequency.

The third embodiment of the present invention is shown in FIG. 3 , which is similar to FIG. 1 . A wired earphone 31 is used instead of the speakers, and a radio/music player is included in the processor 32 for user relaxation and entertainment. Consider using traditional barge-in techniques to interrupt the radio/music output to report heart rate to the user at desired intervals, or to warn the user if the heart rate is too high. The music player may be of any suitable type, but due to its small size an MP3 player is well suited for use.

The earphone can be connected to a wireless processor fixed on the clothes, as in the description related to the watch device in FIG. 2 , or it can be a wireless earphone. But for reliability reasons, and to avoid dropping individual components, it's best to use a wired connection. In addition to the speakers installed on the processor, additional headphones can be added.
