A light emitting unit 260 to scan the 300 constitutes a remote control 200.

The display unit 270 may be configured as an LCD.

As shown in FIG. 4, the pulsation calculator 300 calculates a key value by decoding the light receiving unit 310 for receiving the light emission signal of the light emitting unit 260 and the output signal of the light receiving unit 310. The decoder 320, the level calculator 330 for calculating the output of the decoder 320 and outputting the output to the display device 400 as the level value, and the level value of the level calculator 330 in sequence with the reference value. A pulsation detection unit 340 for detecting pulsations per second in comparison, a pulsation coefficient unit 350 for counting the output value of the pulsation detection unit 340, and a count of the pulsation coefficient unit 350 when counting the clock CLK per minute It consists of the pulsation coefficient reset part 360 which clears a value.

The pulsation detection unit 340 outputs a comparator 341 that outputs 1 when the level value of the level calculator 330 is greater than a reference value, and a flip-flop 342 which latches the output of the comparator 341 at an edge of the clock CLK1. ), The output unit of the flip-flop 342 and the inverter 343, and the output signal of the inverter 343 and the output of the comparator 341, the pulsation coefficient unit 350 beats the beat per second The end gate 344 outputs to the end gate 344.

The pulsation counting unit 350 displays a counter 351 for counting pulsations per second of the pulsing detection unit 304 and the count value of the counter 351 by a clock CLK2 to display the number of beats per minute. It consists of a flip-flop 352 to output to.

The pulsation coefficient reset unit 360 includes a counter 362 for counting a clock CLK, and the counter 351 of the pulsation coefficient unit 350 when the count value of the counter 361 reaches a predetermined value 600. A comparator 362 that outputs a reset signal RST to and a reset signal RST of the comparator 362 and inverts the clock signal CLK2 to a flip-flop 352 of the pulsation coefficient unit 350. It consists of the inverter 363 output.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows. If the user wants to know the heartbeat of himself or another person, after inputting any key for setting the heartbeat checking mode on the key matrix, the voice sensor 210 attached to one side of the remote controller 200 may be used. In close contact with the heart, the voice sensor 210 detects a heartbeat and converts it into an electrical signal and outputs it to the voice amplifier 220.

When the voice amplifier 220 amplifies the electrical signal of the voice sensor 210 by a predetermined level, the analog / digital converter 230 samples a predetermined time interval (for example, 100 ms) and converts the digital signal into a digital signal.

As the analog / digital converter 230 sequentially samples the output signal of the voice amplifier 220, the comparator 240 determines the level value by comparing with the reference level value Vref1. If any reference level value is set and the output value of the analog / digital converter 230 is between each reference level value, the reference level value is determined as the upper or lower level value.

That is, if the sampling value of the analog / digital converter 230 is the same as the waveform of FIG. 5, the comparator 240 determines the code (code1 or code2) as the level value in the case of p1, p2, p8, and p9, and p3, p6. In the case of p7, the code (code2 or code3) is determined as the level value, in the case of p4 and p5, the code (code3 or code4) is determined as the level value, and in the case of p10, the code (code0) is determined as the level value.

At this time, the microcomputer 250 converts the level value calculated by the comparator 240 into a display signal and outputs it to the display unit 270, and simultaneously emits an external kit value corresponding to the level value as a remote controller signal and emits light from the light emitting unit 260. Will be printed.

Here, the microcomputer 250 may not output the display signal obtained by converting the level value to the display unit 270.

The microcomputer 250 prepares an external key value corresponding to each level value determined by the comparator 240 as a table and stores it in an internal memory.

Accordingly, the display unit 270 displays the heartbeat waveform in accordance with the display signal from the microcomputer 250.

Meanwhile, when the light emitter 260 scans the infrared pulsation arithmetic unit 300 according to the remote controller signal of the microcomputer 250, the light receiver 310 receives the emitted light and converts the light into an electrical signal to the decoder 320. Will print.

When the decoder 320 decodes the electrical signal of the light receiver 310 and converts the signal into a code value, the level calculator 330 determines the level value of the corresponding code and outputs the level value to the display device 400.

The display device 400 displays the waveform of the heartbeat by sequentially displaying the level value of the level calculator 330 on one side of the screen.

In addition, when the pulsation detection unit 340 detects the level value of the level calculating unit 330, the comparator 341 compares the reference level value Vref2 and outputs a signal of 1 when the reference level value Vref2 is larger than the reference level value Vref2. 342 latches the output of the comparator 341 according to the clock CLK1.

Assuming that the clock CLK1 is 10 cycles per second, the flip-flop 342 latches the output value of the comparator 341 ten times.

When the output of the flip-flop 342 is inverted in the inverter 343, the AND gate 342 detects the number of beats per second by logically multiplying the output of the comparator 341 and the output of the inverter 343.

For example, when the level value as shown in FIG. 6 is input to the comparator 341, the output value is 0 during the interval t1 and t3 and the output value is 1 during the interval t2, and the output of the flip-flop 342 is 0 during the interval t1. When the output of the AND gate 351 becomes 0 and the interval t2 becomes the output value of the comparator 341 becomes 1, the AND gate 344 inverts the output of the flip-flop 342 which is 0 to the inverter 343. Outputs a value of 1 by logically multiplying the output of the comparator and the output of 1 by the comparator 341, and then outputs a value of 0 from the inverter 343 even though the output value of the comparator 341 remains 1. Therefore, the output value of the AND gate 344 is maintained at 0, and when the interval t3 is reached, the output value of the comparator 341 becomes 0 again, so the AND gate 344 maintains the output value of 0.

Accordingly, in the pulsation counting unit 350, the counter 351 increases the count by 1 whenever the output value of the AND gate 344 of the pulsation detecting unit 340 becomes 1.

When the counter 351 counts the pulsations detected by the pulsation detection unit 340, the pulsation coefficient reset unit 360 causes the comparator 362 to determine a predetermined value 600 as the counter 361 counts the clock CLK1. ) And when the count value of the counter 361 is 600, a signal RST of 0 is output.

When the output RST of the comparator 362 becomes 0, the flip-flop 352 of the pulsation coefficient unit 352, which is inverted by the inverter 363 and the clock CLK2 is inputted, counts the counter value of the counter 351. The counters 351 and 361 at the same time output RST of the comparator 362 will clear the count value.

The count value latched by the flip-flop 352 is input to the display device 400 as the number of beats per minute and displayed on the screen as a number.

As described in detail above, the present invention has an effect that the user can visually recognize the heartbeat state by detecting the heartbeat sound with a detection means attached to one side of the remote controller and displaying the waveform on the screen of the display device. .
