A kind of data processing that algorithm obtains six-axle acceleration sensor is present embodiments provided to prevent from judging by accident: being fallen
It is poured on and hits ground stage resultant acceleration value and reach peak value 3g and resultant acceleration value and fall back to 1g rapidly after tumble.Compared to
The resultant acceleration curve of daily behavior is found: sit down stand up, walk, stair activity, the resultant acceleration maximum bent over are no more than 2g；
The resultant acceleration of running and jump in place is bigger, and highest is close to 3g.In order to which the size of given threshold distinguishes tumble and ADL (day
Normal life activity ability) behavior, setting decision threshold TH1 is 2.5g, in this way major part ADL (daily life active ability) behavior
It can distinguish, so can be set as doubtful tumble as acceleration value > TH1.However running and the motion amplitude jumped
Larger, resultant acceleration amplitude is similar with the resultant acceleration of tumble, and the two is easy to obscure.Therefore use single and acceleration rate threshold
Judgement has unicity.To improve detection accuracy, False Rate is reduced, introduces the angle parameter of six-axle acceleration sensor as two
Secondary judgement.Theoretically, when people falls after a period of time, human body can remain static, and human body and ground should be at this time
Horizontality, Z axis acceleration are 0.Simultaneously after human body is fallen forward or backward, human body X shaft angle degree should be attached in -90 degree and 90 degree
Closely；After human body is fallen to the left or to the right, human body Y-axis angle should nearby float in -90 degree and 90 degree.By testing repeatedly, this
Practical example chooses ± 70 degree and is used as second decision condition threshold value.Although human normal posture can reach sometimes in strenuous exercise
Threshold value, but certainly cannot continue to maintain this value.So this practical example selection requires all to keep this value in 3s, thus may be used
To judge tumble situation in the short time.
In the present embodiment, shape of raising one's hat is judged by two kinds of sensors of six-axle acceleration sensor and heart rate blood oxygen transducer
State, it is intended that raising judges precision, prevents from judging by accident.The reasons why designing in this way is as follows: heart rate blood oxygen transducer is in human vas
Oxyhemoglobin and hemoglobin are by the infrared light near the feux rouges and 900nm near transmitting 660nm, due to arteriopalmus
Congested volume variation causes the light transmittance of light to change, and obtains the heart rate of human body, blood oxygen by volume of data processing operation
Data.When unmanned wear, valid data will not be collected, in ideal circumstances this can be used as whether safe wearing cap according to
According to, however the situation at scene is that operating personnel can largely perspire because of manual labor, due to the appearance of sweat, heart rate sensor
The light of sending can be refracted, it is more likely that can not be acquired valid data, be easily caused erroneous judgement, therefore, six-axle acceleration be added and passes
Sensor auxiliary judgment, when operating personnel's safe wearing cap, roll angle, pitch angle, course angle can be changed significantly, and pass through this
The judgement of a little angle changes can make up above-mentioned deficiency.
