METHOD FOR PROCESSING ACCELERATION MEASUREMENTS, ACCELERATION SENSOR AND ALARM SYSTEM EQUIPPED WITH SUCH SENSORS

摘要

The invention relates to a method for processing instantaneous acceleration measures furnished by an accelerometer (2) along at least one direction with the aim of detecting a condition of the initiation of an alarm signal in which, in a first operating mode, acceleration measures ?k are successively carried out at predetermined time intervals Tk, at each instant, at least one value, called state value, is calculated according to a function of at least a portion of the acceleration measures ?k, each state value is compared to a threshold value, characterized in that if this state value is greater than the threshold value, a second operating mode is switched to, called alarm mode, in which acceleration measures ?'k are successively carried out at predetermined time intervals T'k. The invention also relates to an acceleration sensor (1) that carries out a method of the aforementioned type and to an alarm system equipped with sensors of this type.
