Abstract
The utility model discloses a kind of portable heart rate tester.Mainly solve the problem that people test heart rate inconvenience at any time.Described single-chip microcomputer is connected by circuit catenation principle with signal acquisition module, clock circuit, alarm, display module, power supply, LED respectively, and be arranged in airtight light tight cuboid housing, on housing, the position of corresponding display module and LED is transparent plastic sheet, housing side is provided with the detect aperture of diameter 2.5CM, and light emitting diode and the light sensitive diode of signal acquisition module are oppositely arranged in detect aperture.There is structure simple, with low cost, portable feature.
Description
Technical field
This utility model relates to electronic technology field, specifically a kind of portable Cardiotachometer.
Background technology
Nowadays the method detecting heart rate volatility is innumerable, but the operation of these methods is very complicated, and it is expensive, and need very accurate instrument and equipment, it constrains it and can only use in clinical studies, current heartbeat detection device is on the market usually expensive, and carries inconvenience, cannot meet the needs that people carry out heart rate test at any time.
Utility model content
For solving Problems existing in background technology, the utility model proposes a kind of with low cost, portable portable heart rate tester.
The technical scheme that this utility model adopts is: a kind of portable heart rate tester, comprise single-chip microcomputer, described single-chip microcomputer is connected by circuit catenation principle with signal acquisition module, clock circuit, alarm, display module, power supply, LED respectively, and be arranged in airtight light tight cuboid housing, on housing, the position of corresponding display module and LED is transparent plastic sheet, housing side is provided with the detect aperture of diameter 2.5cm, and light emitting diode and the light sensitive diode of signal acquisition module are oppositely arranged in detect aperture.
The beneficial effects of the utility model are: this utility model structure is simple, be convenient for carrying, with low cost, ordinary electronic table can be used as use when without the need to testing, meet people at any time to the requirement of heart rate test, effective prevention cardiovascular and cerebrovascular disease and the daily inspection to self heart intensity simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model system block diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
A kind of portable heart rate tester as shown in Figure 1, comprise a single-chip microcomputer, on described single-chip microcomputer respectively with signal acquisition module, clock circuit, alarm, display module, power supply, LED is pressed circuit catenation principle and is connected, and be arranged in airtight light tight cuboid housing, effective minimizing ambient light is on the impact of signal acquisition module, on housing, the position of corresponding display module and LED is transparent plastic sheet, housing side is provided with the detect aperture of diameter 2.5cm, light emitting diode and the light sensitive diode of signal acquisition module are oppositely arranged in detect aperture, housing is also provided with the key circuit be connected with single-chip microcomputer.
Be connected with the amplification and rectification circuit be made up of LM358N and 74HC14 between described signal acquisition module and single-chip microcomputer, the signal collected be transformed into the output signal of clear non-jitter, remove external interference signal.
Concrete, utilize when without the need to carrying out heart rate test, ordinary electronic table can be used as use, when carrying out heart rate test, finger is stretched into detect aperture, there will be two kinds of different situations, during one is blood stasis, although finger has blocked the infrared ray that infrared diode is launched, but, because have dark current in photosensitive receiving tube, it is made to cause output potential lower, two is beat pulse phases, when pulse is with heartbeat time, blood flow makes the translucidus of tissue die down, dark current in photosensitive reception diode reduces, output potential raises, collection for heart rate signal is exactly rely on photosensitive receiving tube in fact, the minor alteration of dark current when blood stasis phase and beat pulse phase, amplified by signal again thus obtain the periodic signal of beat pulse, when signal acquisition module collects signal, often gather a heartbeat signal, LED is once glittering, start timing counting simultaneously, when the beats detected is too high or too low, LED is long bright, buzzer siren is reported to the police, this utility model power acquisition 5V lithium battery power supply, can charge, electric power is lasting.
Claims (1)
1. a portable heart rate tester, comprise single-chip microcomputer, signal acquisition module, it is characterized in that: described single-chip microcomputer is connected by circuit catenation principle with signal acquisition module, clock circuit, alarm, display module, power supply, LED respectively, and be arranged in airtight light tight cuboid housing, on housing, the position of corresponding display module and LED is transparent plastic sheet, housing side is provided with the detect aperture of diameter 2.5cm, and light emitting diode and the light sensitive diode of signal acquisition module are oppositely arranged in detect aperture.
