The first sensor includes a door closing position sensor that detects a door closing position signal, which may include any of the following embodiments.

The door closing in-place sensor comprises a control piece and a sensor, the control piece is arranged on the latch bolt, the sensor is arranged on the lock body, and the sensor detects an incomplete latch bolt popup signal to judge that the door is closed in place.

As shown in the schematic diagram of the bolt extension and retraction in the door opening and closing process shown in fig. 3 to 5, in the door opening state, the main bolt 15 retracts into the lock body 19, the lock body 19 leaves the door frame, the latch bolt 11 is completely ejected out of the lock body 19 under the action of the spring 12, in the door closing process, the lock body 19 is close to the door frame, the latch bolt 11 is pressed by the door frame and retracts into the lock body 19, when the door is closed in place, the lock body 19 is aligned with the door frame, the latch bolt 11 is ejected out of the lock body 19 again by the spring 12 and extends into the latch bolt groove 17 of the door frame, and simultaneously, the main bolt 15 extends out of the main bolt groove 18.

The depth of the latch bolt groove 17 on the door frame is controlled to be smaller than the length of the latch bolt 11, when the door is closed in place, the latch bolt 11 is popped out of the latch bolt groove 17 of the door frame, the latch bolt 11 can not be popped out completely due to the limitation of the depth of the latch bolt groove 17, and the length popped out of the latch bolt groove 17 is smaller than the length popped out completely when the door is opened, as shown in fig. 5.

In the embodiment of the photoelectric first sensor shown in fig. 3 to 5, the control member is a light shielding sheet 13 disposed on the latch bolt 11, the sensors are opposed photoelectric switches 14 and 16 fixed on the lock body 19, and disposed at positions corresponding to the light shielding sheet 13 when the latch bolt 11 is ejected into the latch bolt recess 17 and is completely retracted into the lock body 19, and are electrically connected to a processing controller (not shown), the photoelectric switch 14 includes a light emitting tube 141 and a receiving tube 142, and the photoelectric switch 16 includes a light emitting tube 161 and a receiving tube 162. When the door is closed in place, as shown in fig. 5, the latch 11 is partially ejected into the latch recess 17 due to the depth control of the latch recess 17 of the door frame, and the light-shielding plate 13 is located at the position of the photoelectric switch 14, so that the light emitted from the light-emitting tube 141 in the photoelectric switch 14 is shielded by the light-shielding plate 13, and the photoelectric switch 14 is turned off, and meanwhile, the light emitted from the light-emitting tube 161 in the photoelectric switch 16 is irradiated to the receiving tube 162 to be turned on.

In the door opening process, the latch 11 is firstly pulled back to the lock body 19 by the user rotating or a sliding door lock, so that the light shielding sheet 13 leaves the position of the photoelectric switch 14 and moves to the position of the photoelectric switch 16, and the photoelectric switch 14 is switched on and the photoelectric switch 16 is switched off; when the door is opened, the lock body 19 is staggered with the door frame, a user releases the door lock handle, the latch bolt 11 is completely ejected out of the lock body 19 by the spring 12, and the light shielding sheet 13 is separated from the positions of the photoelectric switches 14 and 16, so that the photoelectric switches 14 and 16 are both in a conducting state.

During the door closing process, the latch bolt 11 is pressed by the door frame and is completely retracted into the lock body 19, so that the light shielding sheet 13 is in the position of the photoelectric switch 16, the photoelectric switch 16 is turned off, and the photoelectric switch 14 is not affected and is turned on. When the door is closed to the proper position, the photoelectric switch 14 is turned off, and the photoelectric switch 16 is turned on.

The processing controller judges that the latch bolt 11 is completely ejected according to the simultaneous conduction signals of the photoelectric switches 14 and 16, is in a door opening state, judges that the latch bolt 11 is completely retracted according to the conduction signals of the photoelectric switch 14 and the photoelectric switch 16, is in a door opening and closing process, judges that the latch bolt 11 is not completely ejected according to the disconnection signals of the photoelectric switch 14 and the conduction signals of the photoelectric switch 16, and is in place when the door is closed.

It should be noted that a complete retraction of the latch 11 is required both during opening and closing of the door, i.e. the on and off signals of the photoelectric switch 14 and the photoelectric switch 16 occur, except that the door opening process is started from the door closing in-place state, and the door closing process is started from the door opening state, i.e. the process controller can distinguish the door opening process from the door closing process according to the initial states of the photoelectric switch 14 and the photoelectric switch 16 before the door is opened and closed, if the photoelectric switch 14 is turned off and the photoelectric switch 16 is turned on (the door is closed in place), the state is changed into the state that the photoelectric switch 14 is turned on and the photoelectric switch 16 is turned off, the signal that the latch 11 is completely retracted in the door opening process is judged, if the photoelectric switch 14 is turned on and the photoelectric switch 16 is turned on (door opening state), the state is changed to that the photoelectric switch 14 is turned on and the photoelectric switch 16 is turned off, and the signal that the latch 11 is completely retracted is judged in the door closing process.

Obviously, 1 light-emitting tube can be used as a control element to be arranged on the latch bolt 11, 2 receiving tubes can be used as sensors to be arranged in the lock body 19, the light-emitting tubes are driven to move by the extension of the latch bolt 11 to further control the on-off states of the 2 receiving tubes, and the processing controller judges the door opening and closing process and the door closing in place according to the on-off signals of the 2 receiving tubes.

In addition, 1 magnet can also be regarded as the control piece and set up on the latch bolt, 2 hall sensors are fixed on the lock body to be connected with the processing controller electricity, judge the process of opening and shutting the door according to the magnetic induction signal change of 2 hall sensors. In the state of opening the door, the latch bolt is popped out completely outside lock body 19, magnet staggers 2 hall sensors, 2 hall sensors all can not detect magnetic strength and break off, the latch bolt is pushed by the door frame and retracts into lock body 19 completely in the in-process of closing the door, magnet is pressed close to 1 hall sensor and leaves another, make wherein switch on and another disconnection, when closing the door and target in place, latch bolt 11 part pops out lock body 19, the magnet position changes, the hall sensor disconnection that makes the in-process of closing the door switched on, the hall sensor of disconnection switches on.

Obviously, the positions of the control element and the sensor can be reversed, i.e. the sensor is arranged on the latch bolt and the control element is arranged in the lock body.

It will be appreciated that the position signals of the fully retracted and the incompletely ejected latch tongue may also be detected by other detection means such as a position switch, a contact switch, a travel switch, etc.

In another embodiment of the door closing in-place sensor for detecting a door closing in-place signal, the first sensor comprises a control element and a sensor, the control element is arranged on a door frame, the sensor is arranged on the lock body, the control element on the door frame is over against the sensor on the lock body in a door closing in-place state, and the sensor is used for detecting the over-against signal of the lock body and the door frame to judge that the door is closed in place.

Fig. 6 shows a schematic view of photoelectric detection of door closing position, taking a reflective photoelectric sensor as an example, the control element is a reflective mirror 21 disposed on the door frame 24, the sensor is a reflective photoelectric switch 22 fixed on the lock body 23 and electrically connected to the processing controller, the photoelectric switch 22 includes a light emitting tube 221 and a receiving tube 222, and the lock body 23 is disposed on the door 25. When the door is closed in place, the lock body 23 is attached to the door frame 24, the position of the reflecting mirror 21 is opposite to that of the photoelectric switch 22, light emitted by the light emitting tube 221 is reflected to the receiving tube 222 by the mirror 21 to be conducted, when the door is opened or closed in place, the lock body 23 is staggered or not opposite to the door frame 24, the receiving tube 222 cannot detect the light of the light emitting tube 221 reflected by the mirror 21 and is cut off, and the processing controller judges that the door is closed in place according to a conducting signal of the photoelectric switch 22.

It can be understood that the door closing in-place sensor can also be a door magnet, a contact switch and other detection devices for detecting the attaching right or staggered separation state between the door plate or the door lock and the door frame.

The door closing in-place sensor detects the further embodiment of the door closing in-place signal, the first sensor includes first control, second control and first inductor, second inductor, first control sets up on bumping the tongue, first inductor sets up on the lock body, bumps tongue compression signal through first inductor detection and judges to close the door, the second control sets up on the oblique tongue, the second inductor sets up on the lock body, and it puts in place to close the door to detect the oblique tongue pop-up signal through the second inductor and judge.

The collision tongue is generally designed into a triangular form, and is pressed by colliding with a door frame in the door closing process, and retracts into the lock body to be unchanged until the door is opened, and the collision tongue is ejected out of the lock body by a spring. Unlike the latch tongue, the latch tongue is ejected into a latch tongue groove on the doorframe when the door is closed in place, including being ejected completely or partially.

It should be noted that, the latch bolt may be completely ejected in the door opening state, so that the complete ejection signal of the door closing in place needs to be determined by combining the door closing signal detected by the retraction of the latch bolt, and the complete ejection signal in the door opening state needs to be distinguished from the complete ejection signal in the door opening state.

Compared with the automatic locking controlled by a door closing signal or a key input signal, the automatic locking controlled by a door closing in-place signal can avoid scratching a door frame caused by too early extension of a main bolt or false locking caused by improper door closing. The door closing position detection is preferably described below.

The automatic door lock firstly controls the main bolt and/or the top and bottom hook to lock firstly according to a door closing in-place signal detected by the first sensor. The first lock comprises at least one of the following partial locks: locking a part of the main bolt extending out; or the locking of a part of the top hook and the bottom hook; or the top and bottom hooks are locked without extending out; or the main bolt is fully extended and the top and bottom hook is not extended.

The main bolt is different from the auxiliary bolt such as the oblique bolt or the touch bolt, and generally drives the top and bottom hook to stretch out and draw back, and is the main locking part of the door lock, including the square main bolt or the round main bolt. The fully extended length of the main bolt is generally about 2 cm. The partial extension of the main bolt is relative to the full extension, and the extension length is less than the full extension length, such as a half-lock state extending 1 cm.

The automatic door lock can control the main bolt to partially extend out through controlling the rotation angle of the motor, if the motor rotates for 2 circles, the main bolt can be completely extended out, and half of the main bolt extending out can be achieved by controlling the motor to rotate for 1 circle.

The partial lock also comprises a lock with a hook part extending out. Because the main lock tongue usually links with the world hook, if the main lock tongue part stretches out, the world hook that drives also can only stretch out a part.

In addition, the main lock tongue and the top and bottom hook can be arranged separately and controlled by a main lock tongue driving motor and a top and bottom hook driving motor respectively, the partial locking can control the main lock tongue to partially or completely extend through the main lock tongue driving motor, and the top and bottom hook does not extend. The stretching of the top and bottom hook is usually more energy-consuming than the stretching of the main bolt, and only the main bolt is driven to stretch out without driving the top and bottom hook in a partial locking stage, so that the energy consumption for driving the top and bottom hook to stretch is saved.

Obviously, the part of the top hook and the bottom hook can be controlled to extend out only by driving the rotation angle of the top hook and the bottom hook motor, and the main bolt does not extend out, so that the partial locking of the automatic door lock is realized, and the energy consumption for driving the main bolt to extend and retract is saved by the method.

Through partial locking, the energy consumption for driving the main lock tongue and/or the balance hook to extend out of the rest part can be saved, meanwhile, the subsequent unlocking process is shortened, and the subsequent unlocking energy consumption is saved. For example, in the time period of going out and working, after the first family goes out, the automatic door lock controls the rotation of the motor to partially lock according to the door closing in-place signal, such as half-locking, so that half of locking energy consumption is saved, meanwhile, the family who goes out is facilitated, half of unlocking energy consumption is saved, and the time processes of unlocking and locking are respectively shortened by half. Obviously, the same energy consumption can be saved during the process of entering the door from work. The more family members, the more obvious energy-saving effect.

The automatic door lock controls the main lock tongue and/or the top and bottom hook to partially lock according to the door closing position, and then secondary locking is performed according to a second locking control signal detected by the second sensor on the basis of partial locking, so that the main lock tongue and/or the top and bottom hook are controlled to extend out of the rest part, and complete locking is realized.

The second sensor comprises an intelligent camera, image identification information of family members is established in the intelligent camera, the intelligent camera shoots a doorway area, people entering and leaving the doorway are identified through video image information, a second locking control signal is sent to the processing controller according to the last person entering the doorway, and a second locking control signal is sent to the processing controller according to the last person leaving the doorway.

The automatic door lock is provided with a first wireless communication module, the intelligent camera is provided with a second wireless communication module, and the automatic door lock is in wireless communication connection with the intelligent camera through the first wireless communication module and the second wireless communication module.

The intelligent camera judges whether the user enters or leaves the door according to the door opening and closing state and the movement detection of the user by combining the directions inside and outside the door.

The intelligent camera is arranged on a certain position in a room, such as a wall or a desk, and faces a door to shoot a doorway area so as to shoot a door image, and the intelligent camera is arranged on a wall where the door is located, such as a transverse door frame or a doorway wall in the door, and can shoot the doorway area downwards but cannot shoot the door image.

The indoor intelligent camera can establish a door opening and closing identification model through the collected image information of the opening and closing states of the door, and can identify the door opening and closing state of the door according to the door opening and closing model. In addition, the indoor intelligent camera can also judge the on-off state of the door by combining a door opening and closing signal detected by the intelligent door lock, and the intelligent door lock sends the intelligent camera in a wireless communication mode through the opening and closing signal detected by the first sensor. The indoor intelligent camera can identify the entrance and exit of a user through a video image in the door opening and closing process.

To the user entering, when the door is opened, the indoor intelligent camera can shoot the user entering the door and enter the camera from the outside of the door, turn to close the door, then leave the door lock, move to the indoor until disappearing from the shooting area. For the person who enters the door along with the door, after the door is opened, the intelligent camera shoots that the user enters the camera from the outside of the door and moves towards the indoor direction until the person disappears from the shooting area.

To the user departure, the indoor intelligent camera can shoot the user that departs and get into the camera from the room, and move to the gate until the departure, the user image disappears after closing the door. For the person who goes out along with, after opening the door, the intelligent camera shoots that the user gets into the camera from the indoor, moves to the gate until disappearing from the outdoors.

The intelligent camera in the door, which is arranged on the inner transverse door frame or the door wall in the door, shoots downwards, can look down users entering and exiting the door, and can judge that the users enter and exit according to the moving direction of the users by combining the door opening and closing signal detected by the intelligent door lock.

To the user entering, when the door is opened, the intelligent camera in the door can shoot the user entering the door and enter the camera from the outside of the door, and the door turns to leave the door lock after being closed, moves towards the inside of the room and disappears. For the personnel who enter the door along with, after opening the door, the intelligent camera shoots that the user enters the camera from outdoors, then moves to the room and disappears.

To the user go out, before opening the door, the user that goes out can be shot to the indoor intelligent camera and get into from the room to move to the gate, disappear from the door after opening the door. For the people who go out along with the door, after the door is opened, the intelligent camera shoots that the user enters the camera from the inside of the room, moves towards the door, and then disappears from the outside of the door.

The intelligent camera is arranged on an indoor transverse door frame or a doorway wall, so that the recognition effect of the intelligent camera can be improved through installation, the installation is standardized, and the requirement on video analysis software is reduced.

And establishing image identification information of family members in the intelligent camera, and identifying members entering or leaving according to preset image identification information. The establishing method is that after the intelligent camera is set, the image identification information, especially the image information when the key node is established by collecting the video image of the user in the process of independently entering and exiting the home, such as the image when the user enters the camera, or the image before leaving the camera, or the image when the user opens or closes the door, or the image when the user is at a certain specific position in the shooting area, etc.

The image recognition information is used for distinguishing family members, not for identity authentication, and thus may be face image information, body characteristics such as height and weight, sex characteristics of men and women, and the like. In addition, according to different setting modes of the intelligent camera, the angle for acquiring the image identification information of the user is different, and the image can be a front image, a side image or a top view image.

The intelligent camera identifies the family members entering and exiting the door according to the preset family member information, and sends a second locking control signal of the automatic door lock in a wireless mode.

And the automatic door lock locks for the second time according to the second locking control signal sent by the intelligent camera.

The secondary locking comprises locking of the part of the main bolt extending out of the rest part, for example, the partial locking state of the automatic door lock is a half-lock which drives the main bolt to extend out of a half by rotating a circle through a motor, and the secondary locking can realize complete locking by driving the main bolt to extend out of the half by rotating a circle through a motor.

The secondary locking comprises locking of the part, extending out of the rest part, of the top and bottom hook, for example, the part, locked state of the automatic door lock is that the top and bottom hook extends out by half, and the secondary locking can be realized by rotating the motor by one circle to drive the top and bottom hook to extend out of the back half.

The secondary locking comprises locking with the top and bottom hooks fully extending out, if the partial locking state of the automatic door lock is that the main bolt partially extends out, and the top and bottom hooks do not extend out, the main bolt can be driven to fully extend out through the rotation of the main bolt driving motor, and meanwhile, the top and bottom hooks are driven to fully extend out through the rotation of the top and bottom hook driving motor to realize the complete locking.

The secondary locking comprises locking with the top and bottom hooks fully extended, if the main bolt is fully extended in the partial locking state of the automatic door lock, and the top and bottom hooks are not extended, the top and bottom hooks can be driven to fully extend by rotating the top and bottom hook driving motor to realize the full locking.

In addition, the second sensor also comprises a clock module, a secondary locking control time period is preset in the automatic door lock, and the processing controller controls the automatic door lock to be locked for the second time according to the set time period of the secondary locking.

For example, setting 8:30 am to 17:30 pm as the daytime secondary locking control time period, and setting 18:30 pm to the next morning, 7:30 pm as the nighttime secondary locking control time period. When the user goes out of work in the morning, if the user goes out of work late or does not go to work, the intelligent camera recognizes that the time of the scene signal leaving home is late or cannot occur, and if the set daytime secondary locking time period is 8: 30-17: 30, the automatic door lock controls secondary locking according to the time; similarly, at the time of going home from work at night, if a person returns at night or is not going home on business, the intelligent camera recognizes that the time of the scene signal of the whole house is late or cannot occur, and if the scene signal is in the set night secondary locking time period of 18: 30-7: 30, the automatic door lock controls secondary locking according to the time.

The automatic door lock controls the main bolt and/or the top and bottom hook to perform partial locking and secondary locking every time a user enters or exits in a set secondary locking time period, and two steps of complete locking are completed at one time.

The secondary locking is controlled through the all-at-home scene and the all-away scene, the scene adaptability is strong, the time of the automatic door lock in a partial locking state can be shortened, and the safety is improved; the secondary locking setting time is used as a final control condition, so that the control of the scene of the whole house and the scene of the whole house can be perfected, and the secondary locking is ensured. The scene and the time are used as control conditions of secondary locking, complement each other and meet one requirement.

In the process of entering and exiting the door of a family, the automatic door lock firstly controls the motor to rotate through the driving circuit according to a first locking control signal detected by the first sensor, so that the main lock tongue and/or the top and bottom hook are controlled to partially lock, and then the main lock tongue and/or the top and bottom hook are controlled to secondarily lock according to a second locking control signal detected by the second sensor.

The second sensor detects the second locking control signal, and the second locking control signal can be independently carried out in the whole detection control process without being limited by other processes.

Further, a third sensor is provided in the automatic door lock body to detect a partial or secondary locking signal.

The third sensor comprises a position sensor arranged in the lock body, the position sensor is arranged at the position where the main lock tongue and/or the top and bottom hook partially or completely extend out, and the position sensor is used for detecting the position signal of the main lock tongue and/or the top and bottom hook partially or completely extending out. The position sensor comprises a photoelectric switch, a contact switch, a Hall sensor, a travel switch and the like.

In addition, the third sensor may further include a current sensor for detecting a motor operating current at the time of partial locking or secondary locking.

The current sensor is arranged in the motor circuit and used for detecting the current of the motor. The full-automatic lock drives the main lock tongue and/or the top and bottom hook to extend out for automatic locking through the rotation of the motor, and the current of the motor changes along with the rotation of the motor and the locking of the motor. If the circuit breaks down, and the motor current is 0, then the motor does not rotate, if the door frame takes place to warp or the spring bolt process of stretching out meets the hindrance, the processing controller need overcome the resistance through increasing the motor current to make the main spring bolt stretch out, its electric current is greater than normal operating current. If the current of the motor detected by the current sensor is larger than 0 and smaller than a set threshold value, judging that the motor normally operates to drive the main bolt and/or the top and bottom hook to extend out and lock; if the current of the motor detected by the current sensor is larger than a set threshold value, judging that the motor rotates to drive the main lock tongue and/or the heaven and earth hook to extend out to meet a block, if the current is reduced to a normal operation level, judging that the obstacle is overcome to drive the lock tongue to extend out, and if the current of the motor is continuously increased, judging that locking is in a problem; if the motor current is 0, the judgment circuit fails and cannot be locked.

In addition, the third sensor may also be an angle measuring instrument or a stepping motor, the locked state is determined by detecting a rotation angle of the motor, for both partial locking and secondary locking, the motor needs to rotate a certain angle, for example, the half lock rotates 1 turn, if the motor rotation angle detected by the third sensor is 0 or less than a set threshold, it is determined that the half lock has a problem, and if the motor rotation angle detected by the third sensor is 0 or less than the set threshold during the secondary locking, it is determined that the secondary locking has a problem.

Furthermore, the automatic door lock is provided with a reminder on an inner door panel or/and an outer door panel, and if the door closing in-place signal is detected and the third sensor does not detect part of the locking signal, the processing controller triggers the inner door reminder or the outer door reminder to send out reminding information.

The reminder comprises a sound generating device, such as a voice reminder through a loudspeaker or a buzzing reminder through a buzzer, and the reminder can also be a light emitting device, such as a flashing LED lamp, and the combination of the two is preferable.

According to the embodiment, after the first sensor detects a door closing in-place signal, if the current sensor does not detect the working current of the motor, the processing controller judges that the circuit fails and cannot be partially locked, the reminder is triggered to send out a reminder, or the current of the motor detected by the current sensor is larger than the normal working current, the situation that the door deforms to cause the main bolt and/or the heaven and earth hook to extend out and block and cannot be locked is indicated, the reminder is triggered, or the angle sensor cannot detect the rotation angle of the motor, the processing controller judges that the motor does not drive the main bolt and/or the heaven and earth hook to extend out and lock, the reminder is sent.

For circuit faults, on one hand, reminding can be sent out through the voice reminder, and on the other hand, reminding information can be sent to a mobile phone of a user through wireless communication to remind maintenance.

Further, the automatic door lock is provided with a human body sensor inside or outside the door to detect a human body signal when the door is closed, and the processing controller judges that the user is inside or outside the door according to the human body detection signal and respectively controls the reminder inside or outside the door to send out reminding information.

Further, the human body sensor includes a contact type sensor or a non-contact type human body sensor.

Optionally, the contact type human body sensor includes an input key arranged on a door lock panel inside or outside the door, and the processing controller determines that the user is inside or outside the door according to a key input signal.

Optionally, the touch human body sensor includes a touch sensor disposed on an inside door lock handle or/and an outside door lock handle, and the processing controller determines that the user is inside or outside the door according to a door lock handle touch signal detected by the touch sensor.

Optionally, the contact type human body sensor includes a photoelectric switch arranged on the door lock handle inside or outside the door, for example, a correlation type photoelectric switch is arranged between the handle and the panel, a light emitting tube is arranged on the door lock handle, and a receiving tube is arranged on the door lock panel corresponding to the light emitting tube. When the door is closed, a user holds the handle, due to the shielding of the hand, the light of the light-emitting tube cannot irradiate the receiving tube, the photoelectric switch is not switched on and is in a disconnected state, after the door is closed, if the user leaves the door lock handle, the handle and the panel are not shielded, the light of the light-emitting tube irradiates the receiving tube, and the photoelectric switch is switched on and is in an open state. The processing controller judges whether the user is in the door or out of the door according to the change of the photoelectric switch.

Optionally, the non-contact human body sensor includes an intelligent camera, and after the intelligent camera is closed in place, the user is identified through video image analysis, for example, the intelligent camera is arranged at a certain position in a room, such as on a wall or a table, and shoots a doorway area towards a door, so that an image of the door can be shot, or the intelligent camera is arranged on a transverse door frame or a top wall of the door, and the doorway area can be shot downwards. When closing the door, if the user is discerned to intelligent camera, judge that the user is in the door, if the user is not discerned to the camera in the door, judge that the user of closing the door is in outdoors.

Optionally, the non-contact human body sensor includes a human body infrared sensor, and the processing controller determines that the user is inside or outside the door according to a human body infrared signal sensed by the human body infrared sensor when the door is closed.

Further, the processing controller triggers the in-door reminder to send out reminding information according to detection signals of the clock module and the third sensor. The locking through time control is certain to occur in a scene that people do not go out or family members do not go home completely, people necessarily exist at home at this moment, and if the third sensor does not detect a corresponding locking signal in a set locking control time period, a reminder can be sent out directly through an in-door reminder.
