Method for setting a safety threshold above which an awning should be wound up
A method for setting a safety threshold that triggers the sending, by an acceleration or movement sensor device ( 20 ), of a safety signal that causes a safety movement of a motorized screen ( 11 ) used as a closure or as a sunshade or for privacy, said method comprising the following steps: manual shaking of the screen, recording of a signal produced by a sensor means ( 33 ) during the manual shaking step, and determination of the safety threshold from this recording.
1. A method for setting a safety threshold comprising the following steps:
manual shaking of a motorized screen linked/connected to an acceleration or movement sensor device and used as a closure or as a sunshade for privacy,
automatic recording during the manual shaking step of a signal produced by the sensor device that sends a safety signal when the sensed acceleration or movement sensor device exceeds a safety threshold, the safety signal causing a safety movement of the motorized screen; and
automatic determination and setting of the safety threshold from said recording processed by a microcontroller.
2. The setting method as claimed in claim 1 , also comprising a step of recording the safety threshold in a memory.
3. The setting method as claimed in claim 2 , in which the sensor device automatically enters an operating mode at the end of the recording step.
4. The setting method as claimed in claim 1 , in which the step of determining the safety threshold includes a step of determining the greatest amplitude of the signal in the recording and a step of making said signal amplitude the safety threshold.
5. The setting method as claimed in claim 1 , in which the step of determining the safety threshold includes a step of determining the mean of the ten strongest amplitudes of the signal in the recording and a step of making said mean the safety threshold.
6. The setting method as claimed in claim 1 , including a preliminary step of switching to setting mode, said switching being caused by:
at least one first action of removing and/or opening a housing containing the acceleration or movement sensor, followed by
a second action of putting the housing back in place and/or closing it, within a predetermined time interval.
7. The setting method as claimed in claim 1 , in which the end of the recording step results from the end of a time period triggered at the start of the recording or from a particular action on a remote control acting on the motorized screen.
8. A sensor device for transmitting a safety signal causing a safety movement of a motorized screen used as a closure or as a sunshade or for privacy, said device comprising hardware and software for implementing the setting method as claimed in claim 1 .
