A, three-axis gyroscope sensor: MEMS (MEMS) gyroscope can the positions in Simultaneously test 6 directions, and motion track, accelerates.The maximum effect of three-axis gyroscope is exactly that " measured angular speed, to differentiate the motion state of object; Sensing gyroscope instrument is used in the automatic control system of flying body motion, as level, vertical, pitching, course and angular-rate sensor.

The operation principle of B, triaxial accelerometer sensor: MEMS (MEMS) accelerometer is that the effect that mass is just subject to inertia force is moved in the opposite direction when accelerometer does accelerated motion together with external object (acceleration of this object is exactly acceleration to be measured).The displacement that mass occurs is subject to the restriction of spring and damper, just can record extraneous acceleration magnitude by output voltage.Based on the accelerometer of MEMS, feature richness, can support posture detection, image stabilization, click controls, antitheft, drop and the series function such as freely falling body detection.

Linear (rectilinear motion) and rotary motion (having the motion of change of turning) will be described exactly, need to use gyroscope and accelerometer simultaneously, just following the tracks of better and catch three-dimensional entire motion, is user's experience, accurate navigation system and other function that end user provides presence stronger.In addition, for allowing the gyroscope of designing and making have higher acceleration and lower mechanical noise, or being the rotation error of corrected acceleration meter, needing to use magnetometer to come traditionally with the sensing function that gyroscope realizes, to complete corresponding location.Therefore, the scheme that gyroscope, accelerometer and Gauss meter combine just is becoming the technological means of native system exercise data acquisition.If only use traditional accelerometer, that user obtains or be that reaction is quick but the output that noise is larger, or be react slowly but purer output, and combine with gyroscope as degree of will speed up meter, just can obtain not only pure but also react the output of agility.

MEMS triaxial accelerometer sensor, the characteristic that make use of its triaxial accelerometer is analyzed, and detects the acceleration change in three directions in sportsman's running.User is in horizontal road-work, vertical and two acceleration that advance can present cyclically-varying, as shown in the figure, in the action of running receipts pin, due to center of gravity upwards single pin contact to earth, vertical direction acceleration be in forward increase trend, continue afterwards forward, decentralization bipod touches the end, and acceleration is contrary.Horizontal acceleration reduces when receiving pin, increases when taking a step.Therefore, in road-work, the acceleration that vertical and advance produces and time are roughly a sine curve, and have a peak value at certain point, wherein the acceleration change of vertical direction is maximum, by carrying out detection computations and acceleration rate threshold decision-making to the peak value of track, the step number of user movement can be calculated in real time, also can estimate user's walking distance further according to this.Because it is upper that equipment is placed in sneakers by sportsman at the volley, so the placement direction of equipment is indefinite, we are by the vector length of calculating three acceleration for this reason, obtain the sinusoidal path of a road-work.Second step is peakvalue's checking, have recorded vector length and direction of motion last time, by the change of vector length, the direction of current acceleration can be judged, and compare with last acceleration direction of preserving, if contrary, be namely shortly past peak state, then enter meter step logic and carry out meter step, otherwise give up.By to the number of times of peak value, cumulative can to obtain user's paces of running be finally interference, body-worn equipment has some low amplitude and twitches state fast, if these interfering datas are not rejected, the exact value of note step can be affected, for this interference, can judge to filter by adding upper threshold value and cadence to detection.The fastest running frequency of human body is 5HZ, that is adjacent two steps the time interval be at least greater than 0.2 second, as shown in the figure, we are provided with timespan in note step process, have filtered high-frequency noise, the situation that namely cadence is too fast.Simultaneously by comparing with acceleration magnitude last time, set up certain threshold value Threshold to judge motion whether to belong to effective, effective exercise just can carry out note step.
