Embodiment 1

[0032] Such as figure 1 Shown, a kind of drop detection alarm method of the present invention comprises the following steps:

[0033] (1) System initialization, use the acceleration sensor to collect X, Y, Z three-axis acceleration data, and use the current three-axis acceleration data to set the attitude data before falling;

[0034] (2) Continue to collect X, Y, Z three-axis acceleration data;

[0035] (3) Determine whether the acceleration threshold of at least one axis is between -256 and -2560, if yes, return to step (2), if not, execute step (4);

[0036] (4) Determine whether the drop impact occurs, if so, then perform step (6), if not, then perform step (5);

[0037] (5) update the attitude data before falling, and return to step (2);

[0038] (6) Set or update the post-fall attitude data with the current triaxial acceleration data;

[0039] (7) Judging whether the posture data before falling is consistent with the posture data after falling, if so, then return to ...

Abstract

The invention discloses a falling detecting and alarming method. The falling detecting and alarming method comprises the following steps: (1) initializing a system, collecting acceleration data of X-axis, Y-axis and Z-axis by utilizing an acceleration sensor, and configuring data of posture before falling according to the acceleration data of the X-axis, the Y-axis and the Z-axis at the moment; (2) continuously collecting the acceleration data of the X-axis, the Y-axis and the Z-axis; (3) judging whether an acceleration threshold of at least one axis is within -256 to -2,560 or not, and if yes, returning to perform the step (2); otherwise, performing a step (4) that comprises judging whether falling collision occurs or not, and if yes, performing a step (6) that comprises configuring or updating data of the posture after the falling according to the acceleration data of the X-axis, the Y-axis and the Z-axis at the moment; otherwise, performing a step (5) that comprises updating data of the posture before the falling, and returning to step (2); (7) judging whether the data of the posture before the falling and the data of the posture after the falling are consistent or not, and if yes, returning to step (2); otherwise, performing a step (8) that comprises transmitting falling alarm and returning to step (2).

Description

technical field [0001] The invention belongs to a data detection and alarm method, in particular to a drop detection and alarm method. Background technique [0002] In people's lives, falling is a very dangerous situation, especially for special groups of people, such as the elderly, children, and people suffering from certain diseases. There are many reasons for falls, such as trips caused by inconvenient activities, falls caused by certain diseases, etc. If such falls are not treated and rescued in time, the consequences are often serious. The fall detection device realizes the detection of human falls by detecting the acceleration values ​​of the human body wearing the device in three directions when it is moving, and reports in time through the attached communication module to achieve the purpose of early detection and reporting of human falls. [0003] The present invention also uses an acceleration sensor, which is an electronic device capable of measuring accelerati...
