  • the electromechanical lock actuation device 10 also comprises a position sensor 19 capable of determining an angular position of the drive mechanism 14 and capable of delivering position information ⁇ representative of the angular position of the drive mechanism 14 thus determined. by the position sensor 19.
  • the control unit 17 is configured to trigger, when a condition is verified according to which the position information ⁇ is representative of a locking and / or an unlocking of the lock 100 of opening it 200, the emission of at least one of the first beam of waves F by the first distance sensor 15 and of the second beam of waves F 'by the second distance sensor 15' and to monitor the evolution of at least one of the first distance d and of the second distance d 'during the determined period of time.
  • the position information ⁇ representative of the angular position of the drive mechanism 14 thus determined by the position sensor 19 corresponds to an initial condition, capable of triggering the emission of the beam F by the first distance sensor 15 and / or of the beam F 'by the second distance sensor 15' and to activate the monitoring of the distance d and / or the distance d '.
  • the distance control step is implemented automatically by the control unit 17 when a condition is verified according to which the position information ⁇ is representative of a locking and / or unlocking the lock 100 of the leaf 200.
  • the monitoring of the evolution of the distance d, d determined by the operational distance sensor makes it possible to establish a safety check.
  • the control unit 17 will thus be able to monitor a position or the state (among the partial open state, the total open state or the closed state). partial) of the leaf 200 after unlocking of the lock 100 has been ordered.
  • the control unit 17 will also be able to check that after a command to lock the lock 100, the distance d, determined by the operational distance sensor does not change: otherwise, this could mean that the lock 100 was locked although the opening 200 was not in a position to cooperate with the fixed frame 401 and although the bolts 103, 103 were not able to fulfill their respective roles.
  • the movement sensor 16 undergoes a recalibration step to configure it to its environment after the determined period of time, whether or not a movement of the opening 200 has occurred.
  • environmental conditions such as ambient light, for example, the change in the state of reflection of surfaces, can have an impact on the distance measured by the operational sensor.
  • This recalibration can also be carried out automatically each time the position information ⁇ is representative of a locking and / or an unlocking of the lock 100 of the leaf 200.
  • the electromechanical lock actuator 10 comprises an electric actuator 18 capable of rotating the drive mechanism 14.
  • the control unit 17 is configured to drive the electric actuator 18 in rotation. taking into account the evolution and / or the value of at least one of the first distance d and of the second distance d 'during the determined period of time.
  • the method can include a control step implemented by the control unit 17 after the distance control step, during which the electric actuator 18 is controlled by the control unit 17 taking into account the 'evolution and / or the value of at least one of the first distance d and of the second distance d' during the determined period of time.
  • control unit 17 can thus decide to condition the control of the lock 100 towards its locking or its unlocking by a suitable control of the electric actuator 18, to a condition linked to the distance d, d 'determined by the operational distance sensor.
  • a control of the electric actuator 18 inducing the passage of the lock 100 towards its locking or its unlocking will be conditioned on the determination of a distance by the operational distance sensor confirming that the opening is closed in order to guarantee the correct operation of the lock 100 with respect to a keeper secured to the fixed frame 401.
  • the motion sensor 16 comprises at least one element chosen from the group comprising a magnetometer and an accelerometer, and at least one of the first distance sensor 15 and of the second distance sensor 15 'comprises at least at least one element selected from the group consisting of an ultrasonic beam distance sensor and an optical beam distance sensor
  • sensors 15, 15 ', 16 of this nature advantageously makes it possible to have all the advantages presented above: high measurement precision, good reliability and the guarantee of low power consumption.
  • the electromechanical device for actuating the lock 10 for this purpose comprises a clutch mechanism interposed between the drive mechanism 14 and the electric actuator 18 and varying between a disengaged configuration in which the electric actuator 14 is not coupled to the drive mechanism 14 and at least one engaged configuration in which the electric actuator 18 is coupled to the drive mechanism 14.
  • the electromechanical lock actuator 10 comprises an electrical energy storage device 21, such as stand-alone batteries, for supplying the electrical actuator 18 and the control unit 17.
  • the control unit 17 is suitable for communication with the outside via means of communication of the radiofrequency, wifi, Bluetooth, or equivalent type such as for example ZIGBEE, Zwave or proprietary protocols, in particular with a view to receiving instructions. external to the control unit 17 and the transmission of outgoing information from the control unit 17.
  • the control unit controls the electric actuator 18 from these external instructions and this outgoing information and as a function of distance sensors 15, 15 ', of the movement sensor 16 and of the position sensor 19 in the manner described above.
  • sensors can optionally be integrated into the electromechanical device for actuating the lock 10, for example to determine the mechanical torques of rotation of the rotor 101, the absolute angular position of the rotor 101, its speed of rotation or for determining the presence of a key 106 or of any other element necessary for the operation of the lock 100 or of the electromechanical device for actuating the lock 10.
  • control unit 17 emits an alarm signal in certain identified cases of operation: for example if the state of the opening 200 is considered to be partially (or almost) closed according to the information supplied by the 'one of the distance sensors 15, 15' and that the lock 10 is activated to lock the leaf 200, an alarm signal will be sent to the attention of a user to signal that the leaf 200 cannot be Locked. Likewise, an alarm signal may be emitted if the opening 200 remains in a partially open or partially closed state for a period greater than a predetermined period.
