Abstract
Motor-driven actuating system for roller shutters or sliding barriers or the like, provided with an obstacle-sensing safety device for acquiring samples (ζ(φn)) of at least one main physical parameter (ζ) relating to operation of the actuating system, preferably the torque supplied by the motor, sampled in a set of positions (φn) of the roller shutter along its travel path; for generating from the samples the points of a memorized reference profile (M; W); processor able to calculate the deviation between the profile (M; W) and values subsequently acquired in real time (ζ(φk)) for the same main parameter (ζ) and able to modify the movement of the roller shutter depending on the deviation, wherein the device is designed to analyze and/or process the result of one or more arithmetic logic operations which have as the operand at least the value (Ψ(φk)) of a variable (Ψ) acquired in real time, and, depending on the result, modify the points of the profile (M; W) with operations based on previously memorized values.
