Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a digital display type pulse meter using a low power consumption type display such as a liquid crystal display.

(B) Conventional technology This type of pulse meter not only knows whether the user's pulse rate is within the normal range, but also uses the fact that the pulse rate increases when the user becomes fatigued to prevent the user from exercising too much. It is designed to easily detect overworked conditions, and for this reason, it is powered by batteries for good portability. However,
If such a pulse meter is left unused with the power turned on, it wastes power and the battery life becomes extremely short. There are some devices that turn off the power if no input signal is input for a predetermined period of time, but with these devices, the pulse rate display also disappears, making it inconvenient to use.

(C) Purpose of the Invention The present invention prevents the display of the pulse rate from disappearing even when no input signal is input for a predetermined period of time. This makes it possible to simultaneously extend the life of the battery power source and improve ease of use by retaining pulse rate data.

B) Structure of the Invention The pulse meter of the present invention detects the user's pulse P/V with a detection circuit, calculates the pulse rate with an arithmetic circuit, and displays the pulse rate on a low power consumption display. , the arithmetic circuit is characterized in that it is equipped with an auto-shutoff section that turns off other functions while displaying and holding the pulse rate on the display when no input signal is input for a predetermined period of time. The present value of the pulse rate displayed on the display unit is configured so that it does not disappear even if the unit operates.

((E) Implementation Example - (1) is a pulse meter, and 11 is a pulse rate sensor (2) detected by the clip-type pulse sensor (2) by holding it in the user's earlobe). This device electrically counts the person's pulse pulse and displays the pulse rate per minute on the liquid crystal display (3), which is a low power consumption display.
Measures the user's resting pulse rate, and uses beauty bicycles (4
) etc., it is possible to recognize the state of fatigue by knowing the pulse rate during exercise.

Next, FIG. 2(a) shows a front view of the pulse meter FTL with the display (3) fully lit. In the same figure, (5) is a four-digit numerical display for displaying a stopwatch ,(
6) is a 3-digit numerical display for displaying the measured value of pulse rate, (7) is a stopwatch indicator, (8) is a pacer indicator, (9) is a measurement stop indicator, (10) is a pulse indicator, (n) is the upper limit pulse rate indicator,
(I smell is a lower limit pulse rate indicator, (+3) is an error indicator that shows a false pulse signal, (I4) is a low battery indicator, and (+5) is a sliding power switch, and the ring is a set of buttons. In a group of switches,
In this switch group θ6), (17) is a pulse setting switch that sets the upper and lower limits of the pulse rate and sequentially calls the upper and lower set values, and the ring sets the target time of the stopwatch and also sets the set target time. (+9) is a pacer setting switch for setting the pacer pitch of the pacer that sounds every predetermined time.
(9) is an up switch that counts up the display on the display +51 (81), (211 is a down switch that counts down the display, (3) is a start/stop switch that starts and stops each measurement, ( 231 is the three setting switches (+7) αI
A set value reset switch that resets the upper and lower limit set values, set target time, and pacer pitch of the pulse rate set in I (19) to "0", respectively. A current value reset switch that resets the current value to "0", and □□□ is an all reset switch that resets all set values and current values to "0".

For example, to set the upper and lower limits of the pulse rate, first press the pulse setting switch O'6, and the upper limit pulse rate indicator (11) will light up to indicate that the upper limit is set. as well as a pulse indicator (l
O) lights up to indicate that the numeric display contents of the 3-digit numeric display (6) are in the process of being set, and then the above 3 digits are displayed by pressing the up switch and down switch 1). Now that the numeric display (6) is set to the upper limit setting, turn the pulse setting switch (1') again.
When you press 7), the lower limit pulse rate indicator α lights up to show that the lower limit set value is being set, and the pulse rate indicator (lO) also lights up, and then the up switch - and down switch (21) are pressed. By pressing, the display on the three-digit numerical display (6) is set to the lower limit set value.

If you press the start/stop switch (3) after setting the upper and lower limits of the pulse rate in this way, pulse measurement will start and the usage time from the start will be displayed on the 4-digit numerical display (5). and lights up the stopwatch indicator (7), as well as the three-digit numerical display (6).
) displays the measured value of the pulse rate, and also flashes the pulse rate indicator (lO) in synchronization with this pulse pulse, and if this measured value exceeds the upper limit setting value, the upper limit pulse rate indicator (11) It flashes to notify you of overwork,
On the other hand, if this measured value falls below the lower limit set value, the lower limit pulse rate indicator θ will blink to notify that the pulse rate is abnormal. As shown in the figure,
In the same figure, (Found) is a voltage generating section for liquid crystal, (Found) is a microcomputer for arithmetic processing, (281 is a system clock of 2'71 of this microcomputer consisting of a CR oscillation circuit, and (B) is a voltage drop detection section. , country is the auto shut-off section, (b) is the pulse detection circuit that detects the pulse bus/L' from the pulse sensor (2), and 匈 is the time that is the standard time for timing and measurement of this microcomputer Aki. The base circuit, the ring is a voice discrimination section, and (b) is a speaker for pacer pitch notification and alarm sound generation.

Then, the reduced voltage detection section detects that the capacity of the power supply battery has decreased and the voltage has become below a predetermined voltage, and flashes the dead battery indicator H 10 times to notify the user that the battery is dead. If the voltage has only temporarily decreased due to an overload or other reason, subsequent blinking is stopped to prevent false alarms.

Furthermore, the auto-shutoff section 00) receives input signals such as the pulse pulse and the key input signal from the operation switch group 06) from the microcomputer KN for a fixed period of time.
For example, when there is no input for more than 3 minutes, the current value such as the usage time or pulse rate measurement value displayed on the liquid crystal display (3) is displayed and held.
and other functions such as the audio discrimination section (to) are turned off to perform auto shutoff, and the measurement stop indicator (9) is blinked to notify the user that the auto shut off section is operating. This auto-shutoff section is designed to be released at any time when the input signal is input, and this series of operations is performed according to the number stored in the microcomputer □□□. The processing is performed based on the flowchart shown in FIG.

In addition, Fig. 3 (a) is an explanatory diagram of the state in which the measurement work is stopped by pressing the start/stop switch (4).

(f) Effects of the Invention Therefore, according to the present invention, if an input signal such as a pulse rate value or a key human input signal from an operation twitch group is not input to the arithmetic circuit for a predetermined period of time or more, the pulse rate displayed on the liquid crystal display. It is possible to significantly reduce power consumption by turning off other functions while displaying the current value, such as the measured value of pulse rate, and to extend the life of the battery power supply.In addition, the pulse rate data is retained on the LCD display. Therefore, even if the device is temporarily discontinued and then reused, it can be used timely, making it possible to obtain a pulse meter that is extremely easy to use.
