Description of drawings
Fig. 1 detects the dispensing device structural representation for this utility model;
Fig. 2 is this utility model infrared sensor and signal processing chip electrical block diagram;
Fig. 3 is this utility model receiving and processing device structural representation.
The specific embodiment
With embodiment this utility model is described in further detail with reference to the accompanying drawings below:
This utility model adopts wrist formula wireless test instrument to detect heart rate, this checkout gear comprises two parts, and one is to detect dispensing device, and one is receiving and processing device, after the detection dispensing device detects processing to human heart rate's signal, send to receiving and processing device by wireless mode; Receiving and processing device receives this heart rate signal, this signal is handled, and regulated according to the operation of this heart rate signal application device (as the speed of service of treadmill or exercycle, the resistance of motion etc.), makes it adapt to the heart rate of human body.Like this, just can make the people that on treadmill, exercycle, move compare scientific exercise, and can not reach train on, also avoid the danger that brings because sports load is too high owing to sports load is low excessively.
As shown in Figure 1, detecting dispensing device is fixed in the human aortic place and (as making the wrister shape, wears on human body wrist; Or the finger ring shape, wear on finger; Perhaps make the shape of headgear, be worn on the head; Perhaps make the shape of ankle guard, band is on the human body ankle.), detect dispensing device and comprise heart rate sensor, signal processing chip, microprocessor, wireless signal transmitter, heart rate sensor adopts the SG-105F type, by infrared ray human heart rate's signal detection is carried out in the variation of blood pressure on the wrist and blood fluidity, this micro-signal is input in signal processing chip (adopting the OSW5809 type) the real-time operation amplifier, by operational amplifier signal is carried out sending in the PIC microprocessor after filtering, the amplification, carry out filtration treatment by the PIC microprocessor, carry out wireless transmit by wireless signal transmitter then.
The detection principle of infrared ray heart rate sensor is described as follows:
The infrared ray heartbeat detection is mainly finished by the intravital microvascular volumetric blood of the person.When heart shrinks, during diastole, pulse relaxes with heart at arteries and contracts and periodically beat, and periodically beating causes the variation of volumetric blood.When volumetric blood changes, can cause variation to reflection of light rate and light transmittance.Therefore, if the variation that comes this light of sensing with a photosensitive device measurement just can be come out the cycle identification of heart rate.
Measuring the volumetrical pick off of pulse is made up of light source and optical-electrical converter two parts, the light beam that light source sends sees through the human peripheral blood pipe, when arteriopalmus hyperemia volume-variation, changed this bundle reflection of light rate and absorbance, by optical-electrical converter the optical signal that receives has been converted to the signal of telecommunication then.The infrared ray heart rate sensor utilizes blood that heart is being shunk, causing that the difference of blood light reflex rate detects during diastole.Why adopt infrared ray to detect the situation of volumetric blood change, the method can be avoided the interference of visible light than photoconductive resistance and other visible light coupled apparatus, makes measurement more reliable and more stable.
As shown in Figure 2, A is a heart rate sensor, B is a signal processing, comprise signal processing chip (OSW5809 chip) and peripheral circuit, heart rate sensor is by the pin 10 of signal processing chip, 11 drive, the detected heart rate signal of heart rate sensor is input in the signal processing chip (OSW5809 chip) and carries out filtering, processing and amplifying, the OSW5809 signal processing chip can be according to the power that receives heart rate signal, adjust amplification in real time, has the high processing precision, the OSW5809 chip internal is integrated with the circuit at the infrared ray heart rate measurement, heart rate sensor is driven and handle the faint heart rate signal of identification, and export the pulse confession PIC microprocessor processes of the representative heart beating of a standard.Among the figure: pin 12 is power supply input VDD; Pin 14 is power supply ground VSS; Pin 13 is pulse signal output HPOUT; Pin 15 is for enabling control signal input HIEN.
Pulse signal is input to microprocessor (can adopt the PIC single-chip microcomputer) by pin 13,15, carries out filtration treatment by microprocessor, and microprocessor remains complete heart rate signal according to the characteristics of signal, and those more weak incomplete signals are removed.For example, the too by force or too weak signal that does not belong to the human heart rate is removed, improved the precision of signal processing like this.Signal input wireless signal transmitter after microprocessor processes is launched by wireless signal transmitter.
Receiving and processing device can be arranged on separately outside the application apparatus, also can be directly installed in the application apparatus, receiving and processing device comprises wireless signal receiver, wireless signal receiver receives heart rate signal, in the control chip of the signal input application apparatus that receives, signal is handled, preserves, utilizes, exported by control chip.This control chip is regulated according to the operation of heart rate signal application device, makes it adapt to the heart rate of human body.For example, in the treadmill application apparatus,, reduce movement velocity, the human heart rate is lowered, when the human heart rate is low, can improve movement velocity when detecting runner's heart rate when too high.Also can change the gradient of running board in the treadmill, increase exercise intensity, also can change the resistance of motion of exercycle, can carry out Based Intelligent Control very easily like this.
Detect dispensing device in the technical solutions of the utility model and can make the wrister shape, be worn on the wrist; Also can make the finger ring shape, wear on finger; Perhaps make the shape of headgear, be worn on the head, as long as can detect in the place of human aortic process, and adopt wireless transmission method, very easy to use like this, not needing takes off clothes wears, and does not have the restriction of line; And signal in detecting dispensing device through Combined Processing, improved the precision of signal like this.
