  The invention relates first of all to a method of actuating and learning the end of travel of a device for closing and opening an opening, such as in particular a rolling shutter, blind or the like.

  Said device for closing and opening 1 of an opening comprises a movable member, such as in particular an apron 2 of the shutter, in particular guided by slides 10, moving between two extreme positions and having two physical stops, in particular low 3 and high 4.

  Thus, said device according to the invention has means for constituting two low and high physical stops.

  To do this, the opening and closing device may comprise a locking device 7 ensuring the attachment of the deck 2 roller shutter to the drum 6 and allowing the abutment of the deck at the bottom stop 3 (Figure 1). Such devices are known and in particular disclosed in patent FR-2,584,130.

  The opening and closing device may also include projections 9 located at the bottom of the deck 2 of the shutter abutting in particular against a trunk 8 of said roller shutter in the upper position.

  Said device according to the invention also has means for actuating the movable member, such as in particular an electric motor 5, control means of the movable member, such as a remote remote control or a wired control .

  The device has means for detecting the period of variation of the movable member. It may be in particular a magnetic counting device as presented for example in the patent FR-2.780. 090 consists of a multipole magnetic ring attached to the drum 6 and two Hall effect sensors to identify the direction of variation of the period.

  The device furthermore has logic processing means, such as in particular a logic processing unit comprising a microprocessor and at least one memory.

  The method according to the invention has a normal mode of actuation of the movable member and a learning mode for the recognition of the limit switches.

  According to the invention, the limit switches are recognized automatically by the logic processing means during the operation of the device according to the following steps: the logic processing means causes the transition from the normal operating mode to the learning mode for end-of-stroke recognition as soon as a physical abutment is detected, - the two end positions are recognized successively, in particular by the logical processing means, - and as soon as the end of the step is over, it is possible to pass, in particular by the means processing logic, the learning mode for the recognition of end positions to the normal mode of actuation of the movable member.

  According to one embodiment of the method according to the invention, when the logic processing means observe a physical stop encountered by the movable member in any first direction of actuation, the successive and automatic recognition of the two limit switches takes place. according to the following steps: - the movable member is stopped, in particular by the logic processing means, - the operator, in particular by a manual order of the operator, is actuated in the opposite direction of movement, namely the second direction of actuation, - the movable member is stopped, in particular by the logic processing means, as soon as a physical stop is detected and the configuration of the kinematic link is initialized, - it is actuated, in particular by a manual order of the operator, the movable member in the first actuating direction, - the movable member is stopped, in particular by the logic processing means, as soon as a physical stop is detected and stored ise the configuration of the kinematic link.

  According to a first embodiment, the configuration of the kinematic link consists in taking as origin a first stop, in particular high, and counting and storing the displacement of the movable member between said first stop and a second stop.

  According to another embodiment, for the configuration of the kinematic link, it may be to memorize the end position, particularly high end and the end position, including low.

  According to an embodiment according to the invention, when the method returns to the normal mode of actuation of the movable member, after memorizing, in learning mode, the configuration of the kinematic link, said movable member can no longer be moved only in said second direction of operation.

  Therefore, according to one embodiment, in the normal mode of actuation of the movable member, the logic processing means cause the stop of the movable member for corrected limit values of a value more or less e for said movable member to stop slightly before the two physical stops.

  According to an advantageous embodiment, the logic processing means detect a physical stop by observing the speed drop of the movable member.

  According to another embodiment, the presence of a physical stop is detected by any other means and for example, the measurement of an overcurrent in the winding of the motor, the measurement of an overtorque or the catch-up of a game angular.

  According to one embodiment, the logic processing means readjustment of the limit switches by automatically triggering the transition from the normal mode of actuation of the movable member to the programming mode for the recognition of the limit switches after a predetermined number of steps. 'events.

  To do this, said opening and closing device comprises in particular an event counter, set to zero after each passage in programming mode for recognition of the end of travel, and which is incremented in particular at each descent or climb of the movable member in normal operation mode. The logic processing means then trigger the transition to programming mode as soon as the counter reaches a predetermined number N. According to another embodiment, the logic processing means perform a periodic readjustment of the limit switches. To do this, said device may in particular have a clock which is incremented, the logic means of processing causing the transition to programming mode for the recognition of the end positions for a given period of time.

  The invention also relates to a device for opening and closing an opening, such as in particular a shutter, blind or the like, said opening and closing device comprising a movable member, such as in particular a curtain or an apron roller shutter moving between two extreme positions and comprising two physical stops, actuating means, such as in particular an electric motor, control means of the movable member, such as in particular a remote control, means for detecting the period for moving the movable member, such as a Hall effect sensor identifying the rotation of said motor, and logic processing means, such as in particular a logic processing unit composed of a microprocessor and a memory, said device having a normal mode of actuation of the movable member and a learning mode for the recognition of the limit switches.

  According to the invention, the logic processing means further comprise two ASB and ASH state memories which define a normal mode and respectively a low end-of-travel learning mode and a high-end limit learning mode, the logic processing means causing, when the moving member encounters a high or low stop, setting the ASH and ASB memories to 1 and thus the transition from said normal mode of actuation of the movable member to a mode of learning for recognition of the limit switches, the ASB memory returning to zero upon recognition of the lower limit switch, the ASH memory returning to zero upon recognition of the high limit switch, thus causing the return to the normal mode of actuation of the movable member.

  Thus, when an order is given upwards, if the memory ASH is at zero, then the mode is said to be normal, otherwise the memory ASH is at 1 and then the mode is said learning of high limit. Conversely, when an order is given down, if the ASB memory is zero, then the mode is said to be normal, otherwise if the ASB memory is one, then the mode is called low end limit learning.

  Upon entering the learning mode, the system initializes the two state memories, up-learning (ASH = 1) and down-learning (ASB = 1) as illustrated in FIG. 4. When the system has recognized the two end positions, the two memories are at zero.

  FIG. 3 is a diagram representing the input, output and internal Boolean variables of the control device according to a nonlimiting example.

  The input variables are: - the command command direction high OH and the command command direction low OB. When OH = 1, the operator presses the operation key upwards, when OB = 1, the operator presses the operation key downwards.

  - the boolean variable FC_H and FC_B. When FC_H = 1, the movable member has reached its high end position. When FC_B = 1, the movable member has reached its high end position, - the Boolean variable BP representing the presence of a physical stop. When BP = 1, the logical processing means observe a physical stop.

  The internal Boolean variables are: the ASH and ASB state memories, the Boolean variable S representative of the last direction of actuation of the mobile member. When S = 1, the direction of operation was upwards. When S = 0, the direction of actuation was down.

  The output Boolean variables are the CMB and CMH variables for controlling the motor in the upward direction of movement of the movable member (CMB = 1) or the downward direction of movement of the movable member ( CMB = 1).

  According to one embodiment, said device for closing and opening an opening further comprises a real position counter CP R of the movable member and a limit position counter CP FC.

  Thus, the actual position counter CP_R is incremented or decremented in the direction of movement of the movable member in the normal operating mode.

  The end position counter CP_FC makes it possible to count and memorize the travel of the movable member between the two physical stops in the learning mode. In normal operation mode, its value is blocked. The system then continuously compares the value of the actual position counter with the constant value of the end position counter.

  According to one embodiment, the logic processing means continually compare the value of the actual position counter CP_R with the value of the end-of-stroke position counter CP_FC and causes the actuating means to stop when the actual position counter reaches a number close to zero equivalent to a position + E close to said upper end position, or when the actual position counter reaches a number close to the value of the end position counter equivalent to a position -E of said low end position.

  As shown in FIG. 6 and according to one embodiment, the Boolean variables FC_H and FC_B are defined as follows: FC_B = 1 if the value of the actual position counter CP_R is greater than or equal to the value of the counter end of the CP CP end position cut by an integer NE so that the movable member stops before said bottom stop, - FC_H = 1 if the value of the actual position counter CP_R is less than an integer NE so that the moving member stops before said high stop defined as the origin of the actual position counter CP_R.

  FIG. 5 represents a graph-type diagram illustrating the operation of the mobile element in the normal operating mode.

  Steps 11 and 31 represent the control of the motor respectively upward (CMH = 1) and downward (CMB = 1) after an upward actuation command (OH = 1) and respectively an actuation command to the bottom (OB = 1).

  During steps 11 and 31, the internal Boolean variable S is set to one or to zero in the direction of actuation of the movable member. This variable will keep this state after the end of said step 11 or 31.

  Switching to one of the Boolean high limit variable (FC_H = 1) or respectively the Boolean low limit variable (FC_B = 1) causes the motor to stop. If a physical stop is detected (BP = 1), the state memories ASH and ASB are set to one and the actual position counter CP_R and the end position counter CP_FC are set to zero (step 12).

  The return of the ASH and ASB status memories to zero will allow a new cycle in the operating mode of the movable member.

  According to one embodiment, when the logic processing means detect a physical stop encountered by the movable member 2 in a first direction of actuation, the recognition of the two limit switches takes place according to the following steps: - stop of the movable member, actuation of the movable member in the opposite direction of movement, namely the second direction of actuation, - stopping of the movable member as soon as a physical stop (BP = 1) is detected and set to zero actual position counter CP_R and the end position counter CP_FC, - actuation of the movable member in the first direction of actuation, the actual position counter CP_R remaining at zero, the end position counter CP_FC incrementing according to the movement of the movable member if the first direction of actuation is the upward direction of movement of the movable member (CMH = 1), the actual position counter CP_R and the counter of position of end-of-stroke CP_FC incrementing if the first direction of actuation is the downward direction of movement of the movable member (CMB = 1), - stopping of the movable member as soon as a physical abutment (BP = 1) 30 is detected, the value of the end position counter CP_FC being blocked, and the actual position counter CP_R being, if necessary, unlocked and able to increment or decrement according to the period of displacement of the movable member when returning to normal operation mode.

  Thus, according to FIG. 7, if the transition to the learning mode takes place during the displacement of the movable member upwards (S = 1), then an order is given downwards, and in particular by an order operator downward (OB = 1) operator's manual, to move the movable member (CMB = 1) down to the detection of a lower stop (step 21). As soon as the physical stop is reached (BP = 1), the motor stops and the ASB memory goes to zero, the counters CP_R and CP_FC remaining at zero (step 22).

  The bottom end of the race is found.

  The following order can only be upwards, and in particular by an operator manual up command (OH = 1), to move the movable member upwards (CMH = 1). As illustrated in step 23, the end position counter CP_FC increments (CP_FC + 1), the actual position counter CP_R remains at zero (CP_R = 0). As soon as the flap meets the upper stop (BP = 1), the motor stops and the ASH status memory goes to zero (step 24).

  If the transition to the learning mode is carried out during the movement of the movable member downwards (S = 0) then an order is given upwards, and in particular by an upward actuation command (OH = 1) operator manual, to move the movable member up (MH = 1) until the detection of the high stop (step 41).

  As soon as the stop is reached (BP = 1), the motor stops and the memory ASH goes to zero, the counters CP_R and CP_FC remaining at zero (step 42).

  The following order can only be downward, and in particular by an operator down command (OB = 1) command, to move the movable member down (step 43), the counter end position increments (CP_FC + 1), and is copied to the actual position counter (CP_R + 1). As soon as the flap meets the bottom stop (BP = 1), the motor stops and the ASB state memory goes to zero (step 44). The bottom end of the race is found.

  Thus, the system continuously compares the state of the position counter with the end position counter in combination with the state memories ASH and ASB and the given order. The system thus allows optimum adjustment of the low and high limit switch.

  Naturally, other modes of implementation, within the reach of those skilled in the art, could have been envisaged without departing from the scope of the invention.
