Shoes are the articles that everyone must wear, and are not in the case where other wearable devices equally forget wearing, this Utility model is embedded in warning device in shoes and is very convenient for old man.The utility model uses low-power consumption bluetooth Chip detects without entering suspend mode when activity, has movable brief acceleration sensor to detect that acceleration value is greater than setting When threshold value, an interruption can be generated, wakes up Bluetooth chip.Due to sufficiently by the positioning of mobile phone and remote communicating function, one The button cell of CR2032 can continue a journey three months, hardware size small volume and less weight, remove the cumbersome of lithium battery charging from.Bluetooth core Piece determines that the strategy fallen down determines using double-legged motion information redundancy, reduces erroneous judgement, fails to judge, improves accuracy rate.

The intelligent shoe of warning function is fallen down in order to better understand having for the utility model, below in conjunction with Fig. 1 to Fig. 5 pairs The judgment mode of the intelligent shoe of the utility model is illustrated:

Warning device hardware uses low power dissipation design, without entering suspend mode when activity.Due to sufficiently by means of mobile phone Positioning function and remote communicating function, intelligent shoe itself do not need locating module and remote communication module, power consumption, volume and It is substantially reduced in cost.The hardware of left and right foot intelligent shoe constitute it is the same, by button cell, Bluetooth chip and its peripheral circuit, The compositions such as acceleration sensor chip U2 and its peripheral circuit, temperature-sensitive element and interlock circuit and bluetooth are wireless,

As shown in Fig. 2, although the hardware of left and right foot intelligent shoe constitutes identical, the software journey on the Intelligent hardware of left and right foot Sequence design is different, and left foot is slave, and function is different to host report left foot acceleration abnormality and inclination angle by bluetooth equipment Normal state, right crus of diaphragm are host, and by Bluetooth antenna Y1 module to slave and mobile communication, function is that the acceleration of acquisition right crus of diaphragm is different Then normal state and inclination angle abnormality are fallen down using the abnormality of left and right foot according to falling down decision plan and determine whether to exist Phenomenon finally falls down message of seeking help to mobile phone transmission.The present invention is by the testing result of slave, for host as auxiliary judgment, The case where its detection accuracy is higher, avoids the occurrence of erroneous judgement.

Slave programming flowchart is as shown in figure 4, intelligent shoe needs to calibrate six-axle acceleration sensing after first powering on Device enters suspend mode if data maximin varies less the duration greater than threshold value T1 according to 3-axis acceleration data Otherwise mode acquires the information of voltage of thermistor RT, judges whether shoes are put on by people, only put on just meeting by people in shoes Judge acceleration with the presence or absence of abnormality.Coordinate system such as Fig. 2 is established, when X-axis positive acceleration is greater than threshold value TH1, X-axis negative sense When acceleration is greater than threshold value TH2 or Z axis positive acceleration greater than threshold value TH3, then ACC_ is sent to host by bluetooth Status set indicates that left foot has acceleration abnormal.Then, the inclination angle between acceleration of gravity direction and Z axis negative sense is calculated, i.e., For the angle of sole plane normal orientation and horizontal plane normal orientation.3-axis acceleration data pass through public affairs after low-pass filtering Formula calculates resultant accelerationWhen Z axis acceleration is less than 0, calculating inclination angle is arccos (- z/acc), When Z axis acceleration is greater than 0, calculating inclination angle is 180-arccos (z/acc).When inclination angle is greater than threshold value TH4 and duration When greater than T2, ang_status set is sent to host by Bluetooth antenna Y1, indicating left foot, there are inclination angle exceptions, then constantly Circulation executes the action message of above procedure detection left foot.

Mainframe program design flow diagram is as shown in figure 5, first half acceleration is abnormal and inclination angle abnormality detection is held with slave Row process is the same, then initially enters and falls down decision process.It falls down to be divided into and trips, slips and original place is fallen down three types, trip With slip that abnormal with acceleration and inclination angle is abnormal, original place only inclination angle of falling down is abnormal.When host A CC_status set or After person's slave ACC_status set, in time threshold T3, host ang_status set or slave ang_status are set Position, then determine to be tripped or slipped event, otherwise enters original place and falls down decision process.In time threshold T4, host Ang_status set and slave ang_status set occur simultaneously, then determine that original place, which occurs, falls down event, otherwise constantly follows Ring executes above procedure and carries out falling down detection.When being determined with fall events generation, host is fallen down by bluetooth to mobile phone transmission Help information, mobile phone pop-up, which is shown, falls down message of seeking help, if not cancelling the message in the person of falling down 60 seconds, automatically appeal letter Breath and GPS positioning information are sent to guardian.

It should be noted that the judgement for the type fallen down is real by the software controlled in chip U1 being solidificated in the foot of left and right It is existing, since it is the prior art, nor the protection point of the utility model, is not described in detail herein.

In conclusion provided by the utility model have the intelligent shoe for falling down warning function, is received and added by control module The detection data that velocity measuring module, temperature detecting module are sent, and when judging that user falls down according to detection data, by wireless Warning message is sent to binding terminal by transmitting module, by way of temperature detection and acceleration detection, whether judges user Shoes are worn, judge whether user falls down further according to acceleration detection module detection acceleration information, detection accuracy is high, enables users to It is given treatment in time.

Meanwhile the utility model uses the insertion in two shoes in left and right to fall down detection Intelligent hardware, the left side be slave, The right is host, acquires the action message of left and right foot respectively.It is main under the premise of temperature-sensitive element detects that intelligent shoe is put on by people Machine and slave learn that either party has the acceleration greater than threshold value by acceleration transducer, and in stipulated time threshold range It is interior that either party detects that the inclination angle of acceleration of gravity direction and sole plane normal orientation is greater than greater than the threshold duration time Time threshold then determines to be slipped or tripped；Under the premise of heat-sensitive sensor detects that intelligent shoe is put on by people, Host and slave detect that acceleration of gravity direction and the inclination angle of sole plane normal orientation are big in stipulated time threshold range In threshold value and the duration is greater than time threshold, then determines that original place, which occurs, falls down, and will fall down the mobile phone for being sent to binding, lead to The household of user is crossed, old man can give treatment in time after falling down.

It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to appended by the utility model Scope of protection of the claims.
