Control device for a solar protection means

Abstract

The device is meant to move the solar protection means from a first position, among at least two predetermined positions, toward a second position to adapt to a variation in sunshine. It comprises a logic (6) which breaks down movement from the first to the second position into a minimum of two steps separated by a time interval (T 1 ). A command (STOP) activated by a user during said interval (T 1 ) activates the following step and reduces the interval by a fraction. The activation of an order after the interval (T 1 ) and during the operation of the following step increases the interval (T 1 ) by a fraction. The control device is in this way capable of adapting to the behavior of the user.

1 . A control device for a motorized solar protection means, assuring the movement of the solar protection means from a first position, among at least two positions, towards a second position to suit a variation is sunshine, characterized in that the control device comprises 
 a logic (6) breaking down the movement from the first and the second position into at least two steps separated by a time interval (T 1 ) and capable of modifying a fraction of the interval (T 1 ), and    a stopping means (STOP), the actuation of which during said interval (T 1 ) activates a following step and reduces the said interval by a fraction and the actuation of which after the said interval and during the operation of the following step, increases the said interval by a fraction.    
     
     
         2 . The device according to  claim 1 , characterized in that the logic (6) is designed, and respectively programmed, in such a manner that movement in at least two steps is ordered only when the variation in intensity of the sun changes its direction from that of a monotone variation due to the singular course of the sun.  
     
     
         3 . The device according to  claim 1 , of which the logic comprises a memory in which is stored in stages a positioning function (P=f (E)) of a solar protection means as a function of the intensity of sunshine and comprising a voluntary control means ( 8 ) essentially having positioning priority in the solar protection means, characterized in that the positioning logic is capable of modifying in stages the positioning function stored in response to a manually-introduced positioning order, the logic not responding in all cases to such order if this order is given outside the said interval (T 1 ).  
     
     
         4 . The device according to  claim 3 , characterized in that the voluntary control means are control keys for activating an ascent-descent function of the solar protection means.  
     
     
         5 . The device according to  claim 3 , characterized in that the logic comprises a 
 command interpreter ( 1 ) for powering a motor, the command interpreter monitoring the positions of the solar protection means and the said interval (T 1 ) and executing manual positioning orders,    a course interpreter ( 2 ) having as a purpose learning the course of the step actuator for each cycle of the ascent-descent function and delivering to the command interpreter the minimum and maximum position of the solar protection means,    a position estimator ( 4 ) tasked with calculating the assumed position of different movement requests furnished by the command interpreter to the motor, between the minimum position (P 1 ) and the maximum position (P 16 ), and of communicating to the command interpreter the different estimated positions of the positioning function,    at least one decision block ( 6 ) which is associated with a solar panel ( 5 ), the decision block also allowing output positions, each having an associated output, which are foreseen in the positioning function, the said outputs being connected to the command interpreter and a    training block ( 7 ) associated with the decision block, the training block being tasked with progressive modification of the positioning function each time that the user manually intervenes.    
     
     
         6 . The device according to  claim 5 , characterized in that the device comprises a date and time recording means ( 9 ,  10 ) for the introduction of date and time information in the decision block and in that the decision block is designed in such a manner to modify the positioning function as a function of the amount of sunshine and the date and time, these variables being divided in predetermined portions into a series of discrete levels.  
     
     
         7 . The device according to  claim 5 , characterized in that the device comprises several decision blocks and a decision block selector ( 1 ).  
     
     
         8 . The device according to  claim 7 , characterized in that the device comprises a date and time recording means ( 9 ,  10 ) for the introduction of date and time information in the decision block and in that the decision block is designed in such a manner to modify the positioning function as a function of the amount of sunshine and the date and time, these variables being divided in predetermined portions into a series of discrete levels.  
     
     
         9 . The device according to  claim 1 , characterized in that the means by which the activation has as an effect the reduction or increase of said interval (T 1 ) is through a stop control key (STOP) of the solar protection means.
