Abstract
Method, together with the devices implementing said method, for controlling the closing and opening movements of a movable barrier (103) so as to prevent a dangerous impact with an obstacle or crushing thereof, said movable barrier (103) comprising a closing edge having, positioned thereon, one or more sensors (108) connected to a first transceiver (27b) able to exchange a signal with a second fixed transceiver (27a) in communication with a control unit which manages the movement of the barrier (103), comprising a step defining for said signal a communications protocol consisting of more than two signal configurations (A, B, C, D).
Claims18
A method for controlling closing and opening movements of a movable barrier for preventing accidental impact with an object, said movable barrier comprising a closing edge having, positioned thereon, one or more sensors connected to a first transceiver for exchanging a signal with a second fixed transceiver in communication with a control unit which manages the movement of the barrier;
- the method comprising the steps of:
- (a) defining for said signal a communications protocol consisting of more than two signal configurations;
- (b) detecting with a movement sensor the movement status of the barrier;
- and
- (c) varying the transmission period of said signal configurations after the movement status of the barrier is detected, wherein a first value of the transmission period is used when the barrier is stationary and a second value of the transmission period is used when the barrier is moving, the first value being higher than the second value;
- wherein the second value is greater than zero.
A method for controlling closing and opening movements of a movable barrier for preventing accidental impact with an object, said movable barrier comprising a closing edge having, positioned thereon, at least one sensor connected to a first transceiver for exchanging a signal with a second fixed transceiver in communication with a control unit which manages the movement of the barrier;
- the method comprising the steps of:
- (a) defining for said signal a communications protocol consisting of more than two signal configurations;
- (b) detecting with a movement sensor the movement status of the barrier;
- and
- (c) varying the transmission period of said signal configurations after the movement status of the barrier is detected,
- wherein a first value of the transmission period is used when the barrier is stationary and a second value of the transmission period is used when the barrier is moving, the first value being higher than the second value, and
- when the transmission period has the second value at least two different configuration signals are used depending on the state of the at least one sensor;
- the first and second value being greater than zero.

- the method comprising the steps of:
- (a) defining for said signal a communications protocol consisting of more than two signal configurations;
- (b) detecting with a movement sensor the movement, status of the barrier;
- and
- (c) varying the transmission period of said signal configurations after the movement status of the barrier is detected, wherein a first value of the transmission period is used when the barrier is stationary and a second value of the transmission period is used when the barrier is moving, the first value being higher than the second value;
- the first and second value being greater than zero.
