Compared with prior art, this utility model, by the detection being combined into pedestrian's body athletic posture of three-dimensional angular velocity sensor, three dimension acceleration sensor and dimensionally magnetic field sensor, detects precisely; Fixture in this utility model can be set to various ways, facilitates human body to dress.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, a kind of body motion detector, comprise the fixture 1 and detection box body 2 that are connected, detect in box body 2 and be provided with the sensing acquisition device 21 and single-chip microcomputer 22 that are connected, detect box surface and be provided with display 23, display 23 is connected with single-chip microcomputer 21, is connected with signal modulation circuit 24 between sensing acquisition device 21 and single-chip microcomputer 22.Fixture 1 can be wrist strap, belt or clip fixture, facilitate human body to be worn on hand or with it.
In the present embodiment, sensing acquisition device 21 is sextuple attitude transducer, and this sextuple attitude transducer comprises three axis angular rate sensors and 3-axis acceleration sensor, wherein, three axis angular rate sensors are three-axis gyroscope, and 3-axis acceleration sensor is three axis accelerometer.
Three-dimensional accelerometer can measurement target motion in front and back, up and down, the acceleration information in three directions, left and right, can monitor thus and obtain the acceleration of target in three directions, speed and positional information.These message reflections direction of motion of target, frequency, amplitude and rough motion track information.Three-axis gyroscope can obtain the attitude information such as angular displacement and angular velocity of target travel at three attitude deflections such as the angle of pitch, roll angle, course angle.
Detect box surface and be also provided with warning light, this warning light is connected with single-chip microcomputer.
Embodiment 2
Shown in figure 1, the difference of the present embodiment and embodiment 1 is, in the present embodiment, sensing acquisition device 21 is nine dimension attitude transducers, and this nine dimensions attitude transducer comprises three axis angular rate sensors, 3-axis acceleration sensor and three axle geomagnetic field sensors.Wherein, three axle geomagnetic field sensors (three dimensional magnetometer) can be moved the geomagnetic field variation brought by monitoring objective, earth's magnetic field is a vector, for a fixing place, this vector can be broken down into two components parallel with local level component vertical with local level with.If keep electronic compass and local plane-parallel, so in compass three axles of magnetometer just and these three components be mapped.
Acceleration sensor is then measurement target stressing conditions, in other words opposite outer reference substance, such as, relative to the situation of movement of ground target under power effect; But to the attitude of target relative to ground, then detect degree of accuracy not high.The effect of angular transducer is the rotary motion of measurement device self, but can not determine direction and the position of target.The strong point of magnetometric sensor is the orientation of positioning equipment, can measure the angle on target and all directions four direction, can obtain motion track information more accurately by calibration.Turn meter can have drift along with time lengthening, and accelerometer can provide certain correction; And angular velocity can revise the dynamic error that accelerometer is brought by signal noise at short notice.So both combinations not only can obtain the speed, distance, motion severity, attitudes vibration, period of motion change etc. of object space movement, static error each other or dynamic error mutually can also be corrected.Magnetometer then can give target move integrally azimuth information more accurately.The combination of this three classes sensor, can realize human body target motion in direction, position, displacement, operating frequency, movement range, the precise information such as own rotation angle, just can distinguish human locomotion further, jog, hurry up, jump, and the difference of other compound movements (as wushu, dancing etc.).
