Described heart rate detection module comprises the high-brightness LED that penetrates finger high light for launching, high-pixel camera head.Because capillary in finger is constantly congested along with heartbeat, the brightness presenting is along with heart rate constantly changes, and the brightness that camera receives also constantly changes.And extract pixel value, and by Kalman filter, carry out the optimum estimate of signal, effectively follow the trail of changes in heart rate.
Described automatic power handover module comprises power-supply battery automatic converting module and DC/DC level switch module.LTC4414 modular converter formula system can switch to powered battery in the situation that of power-off, and DC/DC level switch module can provide 3.3V voltage for DSP peripheral hardware, for kernel provides 1.6V voltage.
Described display module comprises LCD.What LCD adopted is FYD12864-0402B module, and embedded Chinese character base is supported serial ports and parallel data transmission.
Described total control module comprises dsp processor.Dsp processor adopts TMS320VC5510A chip.This chip is for Miniature Terminal equipment application scenario, to design especially, and the power consumption of its kernel is little, efficiently the extraction of carries out image data and processing.
The beneficial effects of the utility model are:
Capacitance type fingerprint identification is combined with illuminated heart rate detection, by capacitance type fingerprint, identify and determine one's identity, and by illuminated heart rate detection, judgement card reader's exercise intensity, to determine whether with car for running or running to walk generation.This Novel running device of registering utilizes double check to guarantee the person's of registering the validity of identity and the validity of running.Can effectively stop generation and beat, with car for race, to walk the behavior of generation race.Ensure the amount of exercise of student's every day, in the normal teaching of school, promoted again student's fitness.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.Comprise finger print acquisition module, heart rate detection module.11 is capacitive fingerprint sensing device, for gathering the person's of registering finger print data.13 is high-brightness LED light source, and light transmission finger is irradiated to camera 12, camera by the image transmission gathering to TMS320VC5510A.
Fig. 2 is the utility model hardware block diagram.The utility model is to take TMS320VC55IOA as hardware platform, being equipped with the peripherals such as Flash, SDRAM, fingerprint sensor FPCI011C, high-brightness LED, minisize pick-up head, LCD forms, and connection data storehouse, by the data importing gathering at every turn, set up personal information database.
Fig. 3 is the utility model embodiment process flow diagram.This flow process comprises the following steps.
Step 301,302, system initialization, waits for and interrupting.
