Definitions

  • the present invention relates to a method and a device for monitoring a person carrying the device and for detecting falls of this person, in particular for the elderly but also isolated workers, athletes and any person where the situation of falling represents a risk.

  • Fall detection devices exist and in particular the document EP 1 642 248 A1 discloses a portable device that detects a fall by detecting a difference in height by means of a barometric measurement. Such a measure requires the use of an external reference to eliminate false detections caused by natural variations in pressure, such as those caused by door closures, drafts, particularly those resulting from building ventilation / heating systems. and temperature variations. In addition the power consumption of a permanent barometric device remains significant and much greater than that of an accelerometer.
  • the extraction of the gravity component consists in estimating the gravity vector g by using a sphere of unit radius discretized in several vertices to model the set of possible directions of the unit vector g, and a stochastic calculation to determine the probability carried by each vertex that the vector g is in the direction indicated by this vertex.

  • the detection of a worn state and an unworn state of the device by a user is performed by measuring the variation of the I / Q signal of a radio component of the device.
  • the invention may in particular provide a modeling of the wearer's steps by the analysis of the small recurrent shocks due to the steps which gives the manner in which it moves, said modeling comprising the modeling of the parameters speed of walking, amplitude of the steps, regularity, imbalance possible gait and having one or more signaling stages of significant variations of said parameters may reflect a lack of balance that may lead to a risk of falling.
  • the method of the invention may include the activation of a vibrator at the end of the fall detection validation step.
  • the invention further relates to a portable device for monitoring and detecting falls of a person adapted to implement the method of the invention and which comprises a three-axis accelerometer for detecting falls, a deactivation sensor of alarm, a pressure sensor, a buzzer, calculation means and alarm means.

  • the device and the method of the present invention have the primary objective of helping to keep elderly people at home by preventing the risks of falling by step analysis, by detecting falls if they happen anyway and by sending alarms by radio. to a base connected to a monitoring center or to a mobile telephone equipped with a remote monitoring application in the event of a fall or abnormal behavior. They can also be used for the protection of lone workers or outdoor sportsmen and anyone who is in danger of falling.
  • the device of the invention comprises a sealed housing, similar to a watch case for example, powered by a rechargeable battery or battery which can be worn as a medallion, a bracelet or a belt but which can be miniaturized to be incorporated into a garment or in any item worn.
  • the device is equipped with radio components 5 and an antenna 8 for transmitting alarms and operating data of the device either in low energy Bluetooth (Bluetooth Low Energy) to a mobile phone for example, or in radio in the ISM band 868 Mhz for the dialogue with a base of tele-assistance or a LPWAN network (Low Power Wide Area Network) for example.
  • Bluetooth Bluetooth Low Energy
  • ISM band 868 Mhz for the dialogue with a base of tele-assistance
  • LPWAN network Low Power Wide Area Network

  • the device further comprises two LEDs 11, red LEDs to signal a fall detection and / or the sending of an alarm, a green LED 12 linked to the operation and a push button 13 for manually triggering an alarm.
  • a pseudo-vertical position is set up to reduce false alarms as long as this orientation model is valid.
  • the modeling of the position can be performed since the device maintains a pseudo verticality.

This detection makes it possible to cancel a fall, if the orientation of the device respects the established model, or to confirm it if the model is no longer validated.
  • the device will model the wearer's steps by analyzing, using the accelerometer 3 small recurring shocks due to the steps that gives the manner in which it moves and in particular, the walking speed, the amplitude steps, their regularity, the possible imbalance of the march and to announce important variations likely to translate a lack of equilibrium which could lead to a risk of falling.
  • the fall detection itself is performed by analyzing the measurements acquired by the accelerometer 3.

  • the measurements given by the accelerometer for the 3 axes are a combination of the gravity component and motion components.
  • the fall detection principle of the present invention is schematized in the figure 2 . It consists in analyzing the measurements through three study prisms: the search for the free fall of the device 100 corresponding to a cancellation of the gravity which is symptomatic of a free fall, the analysis of the movements 200 of the person, the fact that the fall of a person is accompanied by movements, and the detection of shocks 300 by detection of the rebound of the accelerometer weight and the variation of the angle of the vector represented by X, Y and Z in the time by means of a computation of the solid angle formed between 2 temporally close samples, this detection being necessary to determine an end of fall.
  • a first series of computations corresponds to the search for the free-fall and comprises a calculation 101 of the norm squared N 2 of the positions X 2 + Y 2 + Z 2 , a storage 102 of n1 values of N 2 .
  • step 205 the free-fall indicator of step 106 is taken into account, which, if it is set, will set the value N 2 ⁇ to a predetermined maximum value.

  • N 2 ⁇ When Va is greater than the threshold Sa, the value of N 2 ⁇ is validated at 207 and the values N 2 , N 2 ⁇ are used in a mathematical function 400 giving a drop relevance value itself compared to a threshold 410 to characterize the fall.
  • the mathematical function which takes into account the value filtered in step 105 of c and the square standard of ⁇ (N 2 ⁇ ) validated (207), integrates in particular a multiplication of these 2 values (y 1 ), the subtraction of a constant to the multiplication result to eliminate minor events (y 2 ).
  • This function makes it possible to detect an exceeding of the threshold followed by a return to a normal state in a determined time characteristic of a fall or at least the end phase of a fall (before even stopping briefly when it is followed by convulsions )
  • the principle of squared standard data analysis makes it necessary to take into account a certain number of phenomena and to filter them. In particular the scaling of noise (amplified by the square), the recovery of signed values when necessary
  • the accelerometer will detect an acceleration which can be interpreted as a return of the gravity component while we are in front of a fall. For this we will isolate the sequences, loss of gravity, return of gravity, loss of gravity.
  • This filtering integrates an autocorrelation of the signals X, Y, Z taken separately on different time scales to detect several characteristic frequency spectra eg in a range of 0.3 to 3 Hz
  • the device acquires the data of the accelerometer in X, Y, Z between 20Hz and 30Hz and more particularly around 25Hz and the accelerometer comprises a low pass filter between 1000Hz and 2000Hz, typically at 1500Hz.
  • the latter is equipped with connection means to the telephone network, radio means compatible with the radio means of the device, processing and calculation means adapted to perform an alarm management and monitoring the device.
