Shown in Fig. 3, a kind of Falls in Old People warning system of the present invention, it forms primarily of sensing unit, microprocessor unit and wireless communication module, described microprocessor unit mainly comprises the SMT32 series monolithic 1 being furnished with data-carrier store 14 outside, be provided with A/D converter 2, high speed SPI bus and USART interface outside this SMT32 series monolithic 1, bus on chip comprises DMA passage; Described A/D converter 2 is connected with 3-axis acceleration sensor 4 and dual spindle gyroscopes 5 respectively by external two-way low-pass filter circuit 3, and described 3-axis acceleration sensor 4 and dual spindle gyroscopes 5 form described sensing unit; Described SMT32 series monolithic 1 is connected to the host computer of data upload that can will handle well by wireless communication module.
Shown in figure, described SMT32 series monolithic 1 is also connected to LCD display 6, button 7, bluetooth 8, ACPS module 9, by voicefrequency circuit 10 external loudspeaker and receiver 11; Described SMT32 series monolithic 1 is connected with the charge power supply 13 of a configuration SIM card 12.
Specific embodiments of the invention are: described dual spindle gyroscopes 5 selects double-shaft MEMS gyroscope IDG-300 of InvenSense company, its range to be ± 500 °/s; Described 3-axis acceleration sensor 4 adopts the 3 axis MEMS acceleration transducer MMA7260Q of TM, and its maximum range is ± 6gn; When ± 6gn range, sensitivity is 200mV/g.
A kind of alarm method utilizing described Falls in Old People warning system to carry out, described alarm method is: based on the recognizer of falling of human motion characterisitic parameter, 3-axis acceleration sensor is utilized to monitor acceleration signature, utilize the change of dual spindle gyroscopes monitoring angle speed, receive accekeration and magnitude of angular velocity by the STM series monolithic be connected and extract characteristic quantity as basis for estimation, the magnitude of angular velocity monitored in time by angular-rate sensor is distinguished as fall sign and daily routines, and judge finally whether fall in conjunction with the posture analysis that acceleration signal obtains, and report to the police after judgement is fallen.
Described recognizer of falling is: first set up human body coordinate system, can produce larger difference in the process of falling with between standard reference system; Fall in process at human body, no matter towards which direction, the speed of vertical direction and position can change, and acceleration and the angle of depression also all can produce change in a big way, and therefore, extracting characteristic quantity with accekeration and magnitude of angular velocity can as the foundation judged;
By to the analysis of falling down data, the design of threshold value diagnostic method is adopted to fall down detection algorithm, α
nfor resultant acceleration value, θ is the value of the angle of pitch, and θ is current time relative to the recruitment of the angle of pitch starting to judge the moment.Minimal value when threshold value thresholding FT1 is for falling down, gets 0.20g
n; To fall down in process accekeration within a certain period of time to increase rapidly, the angle of pitch also can increase simultaneously, makes threshold value FT2 be taken as 3.90g
n; Threshold value FT3 gets 4.80g
n, increase at the angle of pitch and approach to 75
.time, can be judged to fall down more than the situation of FT3.As shown in Figure 4.
The present invention is the technique improvement carried out on the basis of existing technology; what the angle information of human motion judged as behavior of falling by it effectively supplements; construct with 3-axis acceleration sensor MMA7260Q; dual spindle gyroscopes IDG-300; STM32 microprocessor and wireless communication module are behavior of the falling real-time detecting system of core; and utilize the model machine of development to carry out human body daily routines and the research of behavior of falling, propose the recognizer of falling based on human body motion feature parameter.
Sensing unit selection and arrangement.Acceleration signature is an Important Parameters in human body motion feature, during human normal walking, acceleration periodically rule change, and falling the moment, acute variation can be there is in acceleration, the change of acceleration can reflect the change of human motion state, therefore, adopt 3-axis acceleration sensor monitoring acceleration signature, old man is before causing danger property is fallen, there will be a series of warning, the particularly sense of equilibrium worse and worse.The basic characteristics of the elderly's gait are that lower limb muscles convergent force declines, and heelstrike, ankle, knee flexing are slow in one's movements, stretch hip insufficient, and cause walking slowly, stride shortens, and walks discontinuous, and pin can not be lifted to a suitable height; Utilize angular-rate sensor to detect in time to fall sign and distinguish with daily routines.In the process of falling, the change of the angle of pitch is the most obvious, and in addition, the attitude after falling down to the ground is relevant with flip angle, therefore, adopt the change of dual spindle gyroscopes detection angle speed.
