A control method is described, said method being used within an operating system () for roller blinds () or the like having an output shaft (SH) of a motor (M) which transfers rotational movement to a drum () onto which the roller blind is wound, said method comprising the following steps: &#x2014;(i) detecting directly or indirectly the force acting on the drum, or on a member connected thereto, and/or the relative position of the drum, or of a member connected thereto, with respect to a part which is fixed and/or integral with the operating system; &#x2014;(ii) obtaining from the detection operation performed in step (i) a zero value (RZ) representing a stable rest condition of the roller blind; &#x2014;(iii) starting an automatic closing movement of the roller blind should said force and/or said relative position (RR) vary, with respect to the value (RZ) obtained during step (ii), beyond a predefined threshold (T). The method simplifies the constructional design and installation of the operating system, while providing it with protection against wind and impacts.

Operating system for roller blinds with protection against excessive wind

Motor-driven actuating system for roller shutters or sliding barriers or the like, provided with an obstacle-sensing safety device for acquiring samples (&#x3b6;(&#x3c6;n)) of at least one main physical parameter (&#x3b6;) relating to operation of the actuating system, preferably the torque supplied by the motor, sampled in a set of positions (&#x3c6;n) 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 (&#x3b6;(&#x3c6;k)) for the same main parameter (&#x3b6;) 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 (&#x3a8;(&#x3c6;k)) of a variable (&#x3a8;) acquired in real time, and, depending on the result, modify the points of the profile (M; W) with operations based on previously memorized values.

Safety device for an actuating system for roller shutters or sliding barriers

An apparatus for radio-controlled automation systems for opening/closing curtains, entrance doors, rolling shutters, gates, barriers, electrical switches or the like, comprising a radio receiver which is coupled to an electric motor or to an electrical switch and comprising at least one radio transmitter for the remote actuation. The radio receiver comprises means for actuating the electric motor or the electrical switch on the basis of the content of an actuation radio signal which originates from the radio transmitter. The radio receiver comprises a memory storing a certificate which identifies the radio receiver and is adapted to provide an authorization for any operation at the radio receiver. The actuation means comprise stored instructions to perform the operation if the actuation signal comprises, in encoded form, the certificate in addition to a recognition code of the radio transmitter and a control code which corresponds to the operation to be performed.

Method, together with the devices implementing said method, for controlling the closing and opening movements of a movable barrier () so as to prevent a dangerous impact with an obstacle or crushing thereof, said movable barrier () comprising a closing edge having, positioned thereon, one or more sensors () connected to a first transceiver () able to exchange a signal with a second fixed transceiver () in communication with a control unit which manages the movement of the barrier (), comprising a step defining for said signal a communications protocol consisting of more than two signal configurations (A, B, C, D).

Method and device for automatic systems designed to operate movable barriers

Method&#x2014;and device for the implementation thereof intended to provide a protection system for barriers which are movable along an operating path and actuated by a motor, such as roller blinds, gates or the like, comprising the steps of connecting the barrier, with play, to a fixed part () so that the barrier is able to move independently of the action of the motor over a travel section (); defining within the section () a set of safety positions corresponding to a safety position for the barrier; detecting along the travel section () the actual position of the barrier with respect to the fixed part (); preventing or reversing the action of the motor and/or the movement of the barrier when the barrier, inside the travel section (), does not have a position included within the set of safety positions.
