The specific embodiment
For the purpose, technical scheme and the advantage that make invention is clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.
Referring to Fig. 1 to Fig. 3; Bicycle based on mobile phone tests the speed and heart rate monitoring unit; Comprise heart rate measurement device 30, can test the speed sensing device 40 of bicycle speed, the mobile telephone interface device 20 that is electrically connected with mobile phone 10, and the monitoring system 12 that is installed on mobile phone 10; Heart rate measurement device 30 comprises that heart rate inductive probe 31, heart rate signal amplify Shaping Module 32, wireless sending module 33 and power module 34; Power module 34 provides power supply for heart rate measurement device 30; Heart rate inductive probe 31 is sent to heart rate signal amplification Shaping Module 32 with the heart rate signal that monitors and handles, and passes through wireless sending module 33 wireless transmit again; Mobile telephone interface device 20 comprises wireless receiving module 21, signal processing module 22 and data transmitting module 23; Wireless receiving module 21 receives the signal of wireless sending module 33 and speed sensing device 40 transmissions; Signal processing module 22 receives from the signal of wireless receiving module 21 and handles to the received signal, and the signal that data transmitting module 23 will be handled is sent to monitoring system 12; Monitoring system 12 comprises to the supply module 122 of mobile telephone interface device 20 power supplies, data acquisition module 123, filtration module 124, heart rate computing module 125, preserves module 127, heart rate curve plotting module 126, consults module 128, manages the administration module 129 of the data signal of preserving, and the main control module 121 of controlling whole monitoring system 12.
Wherein, Mobile phone 10 is a smart mobile phone; Earphone interface 11 comprises ground terminal 11a, L channel terminal 11b, R channel terminal 11c and mike terminal 11d, and supply module 122 is supplied power to mobile telephone interface device 20 through the L channel terminal 11b and the R channel terminal 11c of earphone interface 11.The sine wave signal that it is 64K that supply module 122 is exported a sample frequency incessantly provides the electric current of about 2.5V voltage and about 100uA to mobile telephone interface device 20.Mobile telephone interface device 20 is electrically connected with the sound channel terminal of the earphone interface 11 of mobile phone 10, with the sine wave signal of the sound channel of mobile phone 10 output behind rectifying and wave-filtering as power supply, need not additional power source, thereby reduce use cost.
Wherein, data acquisition module 123 is the pulse signals that read in data transmitting module 23 transmissions through the mike terminal 11d of mobile phone 10.Gatherer process is exactly the process of recording this pulse signal as audio signal.LPCM (being the linear impulsive coded modulation) technology has been adopted in recording, is a kind of non-compressed audio digitizing technique.Each signal that adopts this technology to collect is an incompressible heart rate signal that sign is arranged.Because when recording is made as 8K, monophonic, heart rate signal to sample frequency and accounts for the 2byte size, so the time span between two heart rate signals is (1/8K) * 1 second=0.000125 second.The function of filtration module 124 is exactly to filter clutter and find out real heart rate signal.When having a length in the pulse signal and be about the heart rate signal of 60ms, the heart rate signal of this moment will fluctuate very big, and always to its extreme value (maximum 32767 and minimum-32768) fluctuation, otherwise fluctuation is just very little.Utilize these characteristics to remove clutter just, find out heartbeat signal.
Bicycle based on mobile phone tests the speed and the rhythm of the heart method, may further comprise the steps:

Step 33: the heart rate signal after 125 pairs of filtrations of heart rate computing module calculates;
Step 34: heart rate curve plotting module 126 is drawn heart rate curve and rate curve; The heart rate curve: the time is the X axle, and heart rate value is the Y axle; Rate curve: the time is the X axle, and speed is the Y axle.
Further, said step 32 specifically may further comprise the steps:
A, obtain N with the heart rate signal S that collects square;
The meansigma methods of b, 10 adjacent N of calculating obtains G;
C, comparison G and constant n, n are 100000000;
When G >=n, the heart rate signal of correspondence is made as 1;
When G < during n, is made as 0 with the heart rate signal of correspondence;
D, when the heart rate signal continuously occurs 480 1, this signal is a heart rate signal; Otherwise this signal is assorted signal.
Sample frequency is that 8K and heart rate signal length are about 60ms during recording, so about 480 (8000*0.06) to occur continuously individual 1 the time when the heart rate signal, this signal is a heart rate signal; Otherwise less than 480 or all be assorted signal greater than 480.So just can obtain a real heart rate signal pulse.
Further, said step 33 specifically may further comprise the steps:
Time span between e, two the adjacent heart rate signals is T, and heart rate value HR is:
HR=1 minute/(T+60ms);
If this HR value between 40-240, then keeps this HR value; Otherwise, give up this HR value.The unit of HR is time/minute.
Further, said step 3 also comprises the preservation data and consults historical data; Be specially:
Step 35: preserve data, preserve module 127 heart rate computing module 125 data processed are stored in mobile phone 10 disks;
Step 36: consult historical data, consult the data that module 128 reading and saving modules 127 are preserved, heart rate curve plotting module 126 is depicted as heart rate curve and rate curve with these data.
Further, said step 3 also comprises the data that management process 35 is preserved; Be specially:
Step 37: the data that management process 35 is preserved, 129 pairs of administration modules are preserved data to be increased, deletes or retouching operation.
