Yet another embodiment of the second sensor detects lock.

The second sensor is a current sensor, is arranged in the motor driving circuit and detects the current of the motor. The full-automatic lock drives the main lock tongue 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, and its electric current is greater than normal rotation current. After the door closing action is finished or a user turns to leave the door lock, the locking state of the full-automatic door lock can be judged through the motor current detected by the current sensor, and if the motor current detected by the current sensor is larger than 0 and smaller than a set threshold value, the motor is judged to normally operate to drive a main bolt or a heaven and earth hook to extend out for locking; 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 or the top and bottom 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 has a problem; if the motor current is 0, the judgment circuit fails and cannot be locked. 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.

It can be understood that the second sensor may also be an angle measuring instrument or a stepping motor, and the locked state is determined by detecting a rotation angle of the motor, for normal locking, the motor needs to rotate a certain angle, for example, 2 turns, and if the rotation angle of the motor detected by the second sensor is 0 or less than a set threshold, it is determined that a problem occurs in locking.

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

The contact type human body sensor comprises a touch sensor arranged on a door inner or/and door outer door lock handle, and after the door is closed, if a handle touch signal detected by the touch sensor disappears, the user hand is judged to leave the door lock handle, the door closing action is finished, and the user is ready to leave the door lock.

In addition, the contact type human body sensor also comprises a photoelectric switch arranged on the door inner or/and door outer lock handle, and the progress of the door closing action of a user is judged according to the detection signal change of the photoelectric switch. For example, a correlation type photoelectric switch is provided between the handle and the panel, a light emitting tube is provided on the door lock handle, and a receiving tube is provided 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. After the door is closed, if the photoelectric switch is switched from off to on, the user hand is judged to leave the door lock handle, the door closing action is finished, and the user is ready to leave the door lock.

The non-contact human body sensor comprises a wireless communication module, and whether the user leaves the door lock or not is judged through wireless communication between the wireless communication module and a mobile terminal carried by the user.

The method for judging whether the user leaves the door lock through the mobile terminal is characterized in that the intelligent door lock is in near-field wireless communication with the mobile terminal through the wireless communication module, and after the door is closed, the intelligent door lock judges whether the user leaves the door lock according to the detected wireless signal intensity of the mobile terminal. The near field wireless communication comprises Wi-Fi, Bluetooth, infrared rays, ultra wide band, RFID, ZigBee, NFC and the like. The following description will take bluetooth technology as an example.

When the user closes the door, the intelligent door lock detects the intensity of a mobile terminal wireless signal carried by the user when the door is closed through the wireless communication module according to a door closing signal detected by the first sensor, the intensity serves as a leaving judgment threshold value, and after the door is closed, if the intensity of the mobile terminal wireless signal detected by the intelligent door lock is smaller than the detection value, the user is judged to have left the door lock. When a user closes the door, the intelligent door lock detects a signal intensity value of the mobile terminal and judges whether the mobile terminal leaves or not according to the comparison of the signal intensity value and the intensity value. Through the comparison of the signal intensity of the mobile terminal detected after the intelligent door lock is closed and the judgment threshold value when the intelligent door lock is closed, the distance from the door lock after the user is closed can be determined, the difference value between the two distances corresponds to the distance between the mobile terminal and the intelligent door lock, the larger the difference is, the farther the user leaves the door lock relatively, and according to the precision of the Bluetooth technology, the reminding can be triggered when the user leaves the door lock for 1 meter. The method is simple and has strong scene adaptability.

In addition, a signal intensity judgment threshold value can be preset in the intelligent door lock, and after the door is closed, if the Bluetooth signal intensity of the mobile terminal detected by the intelligent door lock is smaller than the set threshold value, the fact that the user carries the mobile terminal to leave the door lock is judged. The signal intensity judgment threshold value can be manually set in a setting mode, and can also be automatically established through a statistical method, for example, the intelligent door lock detects the Bluetooth signal intensity of the mobile terminal when the door is closed, a statistical value such as an average value is calculated through detection data in a certain period to serve as the judgment threshold value, and after the door is closed, if the Bluetooth signal intensity of the mobile terminal detected by the intelligent door lock is smaller than the statistical value, the user is judged to leave the door lock. The judgment threshold established based on the statistical method can be adapted to various different scenes or environments and can be adjusted according to later changes.

The other method for judging that the user leaves the door lock through the mobile terminal is to position the mobile terminal through a wireless positioning technology, and after the door is closed, if the distance between the position of the positioned mobile terminal and the position of the intelligent door lock is larger than a set threshold value, the user is judged to leave the door lock. Wireless location includes outdoors and indoor, and outdoor location technique includes LBS, WIFI etc. and indoor location technique includes WIFI, bluetooth, UWB etc. wherein to UWB's positioning accuracy is highest, can reach 10 centimetres, and the real-time is the strongest. Indoor positioning needs enough positioning nodes, and besides the intelligent door lock, the positioning devices can be arranged at other fixed positions in a room to construct a complete indoor positioning system.

The position relation between the intelligent door lock and the mobile terminal is judged through wireless positioning, a judgment range is set by taking the position of the intelligent door lock as a center, for example, a radius range of 0.5-1.0 meter can be set by taking the intelligent door lock as the center based on a UWB positioning technology, after the door is closed, an indoor position coordinate of the mobile terminal is monitored, and if the indoor position coordinate is out of the set range or the distance between the intelligent door lock and the mobile terminal is larger than a set radius threshold value, the fact that a user leaves the door lock is judged.

It is worth noting that if the user enters and exits the door without carrying the mobile terminal, the mobile terminal bluetooth signal intensity detected by the intelligent door lock is 0 when the door is closed and after the door is closed, or the system cannot determine the position coordinate of the mobile terminal, the intelligent door lock can judge that the user leaves the door lock when the door is closed and after the door is closed (and the corresponding signal intensity is 0 at a longer distance or cannot be positioned at infinity), and if the locking signal is not detected, the intelligent door lock immediately triggers the reminding.

By monitoring the process that the user leaves the door lock, such as the intelligent door lock detects the change process of the Bluetooth signal intensity of the mobile terminal, or the position change process of the mobile terminal monitored by the system, the speed of the user entering or exiting the door can be judged, therefore, the reminder may be triggered at an appropriate distance from the door lock based on user characteristics, such as for an acute user with a fast speed of entering or exiting the door, the locking speed is also high, after the door is closed, a prompt is sent out immediately when the signal intensity of the mobile terminal is smaller than the judgment threshold value, or a smaller position reminding range is set, so that reminding delay caused by remote reminding is avoided, and for the old users with low speed, the locking speed of the mobile terminal can be slow, and the mobile terminal can send out a prompt after the signal intensity of the mobile terminal is smaller than the judgment threshold value by a certain range or set a slightly larger position prompting range, so that the prompt is avoided being sent out in the locking process of a user.

The non-contact human body sensor further comprises an intelligent camera for shooting a doorway area, and the intelligent camera analyzes and identifies that a user leaves the door lock according to a video image of the user in the doorway area. The intelligent door lock is in wired or wireless communication with the intelligent camera, after the door is closed, the intelligent camera analyzes and identifies user behaviors through video images, judges whether a user turns or leaves the door lock, and sends the intelligent door lock.

The setting mode of intelligent camera has three kinds, one is that setting up somewhere in the room for on the wall or the desk, towards the room door and shoot the gate region, can shoot the room door image, another kind is the setting on the wall at room door horizontal door frame or room door place, for example in the door or on the outer horizontal door frame or the door paring of door, can shoot the gate region downwards, but can not shoot the room door image, another kind is in setting up cat eye or the intelligent lock on the door again, transversely shoots before the door or behind the door video image.

The user behaviors comprise turning or moving behaviors of a user at the door, and the intelligent camera judges the end of the door closing action through the turning of the user or identifies the user to leave the door lock through the moving process.

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. The indoor intelligent camera can shoot the whole process of opening the door, entering the door and closing the door to leave the door lock of a user entering the door, the user faces the camera when entering the door, the camera faces back to or is laterally opposite to the camera when closing the door, and the door turns around and moves away from the door lock after being closed.

The indoor intelligent camera can also be combined with a door opening and closing signal detected by the intelligent door lock, the intelligent camera is sent in a wireless mode when the intelligent door lock detects a door closing signal, and the indoor intelligent camera judges that the door closing action is finished or the user leaves the door lock according to the turning action or the moving process of the user who enters the door after the door is closed.

The intelligent camera that sets up on door internal horizontal door frame or door paring wall shoots downwards, can overlook the user that enters the door, and intelligent camera can combine the switch door signal that intelligent lock detected, sends intelligent camera through wireless mode when intelligent lock detects the signal of closing the door, and the door is closed according to the turn-around action or the removal process of user after closing the door to the interior camera, and the judgement is closed the door and is moved the end or the user leaves the lock. Obviously, the intelligent camera arranged on the transverse door frame or the door top wall outside the door can look down the user who goes out of the door, and the user can judge that the door closing action is finished or the user leaves the door lock by recognizing the turning action or the moving process of the user who goes out of the door.

In addition, the intelligent camera can also identify that the user leaves the door lock through the distance between the user at the door and the door of the room.

The intelligent camera arranged in the house can judge the distance between the user and the house door by comparing the image relative relationship between the house door and the user. Firstly, the intelligent camera collects videos of a user entering a door independently, when the user closes the door, for example, a door closing signal is detected in the intelligent door lock, the intelligent camera establishes a user door closing recognition model according to the relative relation between the user image size and the room door image size, then the user leaves the room door and moves towards the intelligent camera, the user image size is increased, the relative relation between the user image size and the room door image size is changed, and the distance between the user and the room door can be corresponding to the ratio between the user image size and the room door image size. If the intelligent camera does not face the room door, the deviation angle between the intelligent camera and the room door is large, the left and right positions of the user relative to the room door in the image are also considered in the user door closing recognition model, and the user is recognized to leave the room door through the left and right deviation of the user image relative to the room door image.

The intelligent camera that sets up on horizontal door frame or door headwall can't shoot the room door, but camera position itself is on the room door, sets up the below that can make the room door be in the image through the installation, to same model intelligent camera, sets for when setting up height and camera lens angle, and arbitrary pixel coordinate in the image just can also be known with the relation of room door. Through the mounting height and the shooting angle that set up intelligent camera, can make image lower boundary be close to the room door as far as possible, when the user is in certain distance from the room door, for example when 30 centimetres, or 50 centimetres, get into and shoot the scope.

In order to improve the image plane coordinate precision and reduce errors caused by lens mapping, the height of the intelligent camera on the wall can be improved, for example, the intelligent camera is 2.0-2.5 meters away from the ground or is vertically shot downwards as far as possible, so that the overlooking effect is improved.

To the intelligent camera that sets up in cat eye or intelligent lock, can only transversely shoot the user video image information that is in the room door front and back, can not shoot the room door, can be connected with intelligent lock through wired or wireless mode. The setting is shot to the door outside in the intelligent camera in the cat eye or the intelligent lock panel of door outside, the video image when the user closed the door is shot to the signal of closing the door that detects according to the intelligent lock, then according to the image change of this user after closing the door, judge user's turn around action or removal process, for example can discern user's turn around process by the change of front to the side or to the back by the face or the health that the user faced the camera when passing through the contrast and closing the door, or can discern the process of closing the door through the reduction of contrast and user's image size when closing the door, the user of going out leaves the process of lock.

Furthermore, the intelligent camera arranged in the door outer peephole or the door lock panel can determine the relation between the human body image size reduction proportion and the distance between the human body and the camera through tests when the door is closed, a model for judging the distance between the user and the camera through the user image size reduction proportion when the door is closed is established, and the distance between the user and the door lock is identified after the door is closed.

Obviously, if the intelligent camera in the door inner peephole or the intelligent door lock panel is arranged to shoot the video image of the door entering user, the turning or leaving action or process of the door entering user can be identified after the door is closed.

Relative and the intelligent camera who sets up in the room, set up the intelligent camera on horizontal door frame or the door crown wall or in cat eye or the intelligent lock, can set up the recognition effect that improves the intelligent camera through the installation to make the installation standardized, reduce the requirement to video analysis software.

Also can combine the time factor, video image analysis discernment user to the regional user in gate leaves the lock process through intelligent camera, judge the speed that the user went in and out the door, select to leave the lock in the user suitable opportunity according to the user characteristic and trigger the warning, for example to the urgent user of fast speed, it is also fast to lock speed on it, should close the door and turn back the user and prepare to leave the time and remind, avoid causing the warning delay, to the old user that the speed is slow, it is also possible slowly to lock the speed, after closing the door, can leave the room door after the certain distance at the user and send the warning, avoid sending the warning at the user in-process of locking.

The non-contact human body sensor also comprises a distance detector.

The distance detector comprises an ultrasonic distance meter, an ultrasonic transmitter and an ultrasonic receiver are arranged on a panel of the intelligent door lock, the intelligent door lock controls the ultrasonic transmitter to transmit ultrasonic waves and the ultrasonic receiver to receive reflected ultrasonic waves according to a door closing signal, the distance of a user is judged through a phase method, an amplitude method, a time method and the like according to reflected echoes received by the ultrasonic receiver, and if the distance exceeds a set threshold value, the user is judged to leave the door lock.

The distance detector comprises a microwave radar distance meter, a microwave radar transmitter and a microwave radar receiver are arranged on the intelligent door lock panel, the processing controller calculates the distance between a human body and the door lock according to the transmitting and receiving time difference of microwave radar signals, and if the distance exceeds a set threshold value, the user is judged to leave the door lock.

In addition, the intelligent door lock can also judge that the user leaves the door lock according to the human body distance change that the distance detection appearance detected, detects the human body distance when the record was closed the door promptly, if the human body distance grow after closing the door, judges that the user leaves the door lock.

The speed that the user leaves the lock through the distance detector monitoring can combine the time factor equally, and it is different according to the user speed of leaving, can set for different warning judgement distance, for example to the user of rapidity fast, it is short to leave the judgement distance, for example 30~50 centimetres, to the old user that the speed is slow, it is slightly longer to leave the judgement distance, for example 50~100 centimetres.

The non-contact human body sensor also comprises a human body infrared sensor arranged on the door lock panel, and the processing controller judges that the user leaves the door lock according to the change of the human body infrared signal sensed by the human body infrared sensor from the existence to the nonexistence after the door is closed. In order to prevent the user from being far away from the door lock to trigger the reminding, the sensing range of the human body infrared sensor can be 0.5-1.0 m, so that when the user leaves the door lock by 0.5-1.0 m, the human body infrared signal sensed by the human body infrared sensor changes, and the user is judged to leave the door lock.

When the first sensor detects a door closing signal, if the human body sensor monitors that the door closing action of the user is finished or the user leaves the door lock, but the second sensor does not detect a locking signal, the user is judged to leave the door when the door is not locked, and the reminder is triggered to send out reminding information. The human body sensor detects the user behavior and judges whether the user leaves, and the detection of the locking signal by the human body sensor and the detection of the locking signal by the second sensor are not in sequence and can be carried out after the door closing signal is detected.

When the door is closed, if the human body sensor monitors that the door closing action of the user is finished or the door lock is left, and the second sensor does not detect a locking signal, the user forgets to lift the locked door after the door is closed, or the automatic door lock stretches out of the main bolt, fails to be closed and is not locked, and the reminder is triggered to send out unlocking 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.

For an automatic door lock, if a user does not close the door in place or the door deforms, the door frame blocks the extension of the main bolt or the top and bottom hook, and under the continuous effort of a motor or a spring, the main bolt or the top and bottom hook overcomes the door frame to extend, and pushes the door to stagger the door frame, so that the false locking phenomenon of locking and door virtual masking is caused.

If the first sensor detects a door closing signal, the user is judged to finish the door closing action or leave the door lock according to the detection information of the human body sensor, then the second sensor detects a locking signal, the door closing signal detected by the first sensor disappears, a false lock is judged to appear, and the automatic door lock sends out reminding information. The false lock phenomenon usually occurs under the condition that the problem occurs in locking and the problem is not timely remedied, namely, the main lock tongue or the heaven and earth hook does not extend out when the door is closed, then the main lock tongue or the heaven and earth hook extends out and the door is hidden, and the processing controller triggers the reminder to send out false lock reminding information.

The unlocking or false locking can be reminded through the voice of the loudspeaker, the unlocking or false locking can also be reminded through different buzzing modes of the buzzer, for example, the buzzing interval can also be reminded through the buzzer along with different light-emitting modes, for example, the LED lamp flickers in buzzing are distinguished.

Furthermore, the reminder comprises a first reminder and a second reminder which are respectively arranged on the door inner panel and the door outer panel, the controller controls the first reminder and the second reminder to simultaneously send out the reminding information of not locking, and no matter whether a user is located in the door or outside the door, the user can hear or see the reminding information.

Furthermore, according to monitoring signals of users inside or outside the door, the intelligent door lock analyzes and judges that the users are inside or outside the door when the door is closed, and respectively controls the reminder inside or outside the door to send out a prompt.

The intelligent door lock judges whether the user is in the door or out of the door according to the wireless signal intensity of the mobile terminal detected when the door is closed. Taking bluetooth communication as an example, set up bluetooth module on intelligence lock every external panel, shelter from interior bluetooth signal through the burglary-resisting door, or set up a metal and shelter from the ware on intelligence lock every external panel, weaken interior bluetooth signal intensity. When the door is closed, the intensity of the Bluetooth signal of the mobile terminal outside the door detected by the intelligent door lock is greater than that of the Bluetooth signal of the mobile terminal inside the door. Set for the intensity judgement threshold value outside the door in one, when closing the door, if the mobile terminal bluetooth signal intensity that intelligent lock detected is greater than and sets for the threshold value, judge and be in outdoors, be less than and set for the threshold value, judge and be in indoors.

In addition, also can respectively set up a bluetooth module on the inside and outside both sides board of intelligence lock, when closing the door, the mobile terminal bluetooth signal intensity's that two bluetooth modules detected intensity is judged according to the intelligence lock, judges that mobile terminal is in the door or outdoors. For the indoor mobile terminal, the signal intensity detected by the indoor Bluetooth module is greater than that detected by the outdoor Bluetooth module. On the contrary, for the mobile terminal outside the door, the signal intensity detected by the indoor Bluetooth module is smaller than that detected by the outdoor Bluetooth module.

The intelligent camera can also judge whether the user is in the door or out of the door according to the existence of the identified user when the door is closed. When closing the door, set up in room (door) or to the user of discerning of the intelligent camera of shooting in the room (door), judge that the user is in the door, if the user is not discerned to the camera, judge that the user is in outdoors. On the contrary, when the door is closed, if the user is identified by the intelligent camera arranged outside the house (door) or shot outside the house (door), the user is judged to be outside the door, and if the user is not identified by the camera, the user is judged to be inside the door.

Moreover, whether the user is in the door or out of the door can be judged according to the existence of the induction signal of the human body infrared inductor. For example, when closing the door, if set up the human infrared signal of infrared human sensor on intelligent lock outer panel and detect human infrared signal, judge that the user is in outdoors, if do not detect human infrared signal, judge that the user is in indoors. And vice versa.

In addition, whether the user is in the door or out of the door can be judged according to the existence of the reflection signal detected by the distance detector. For example, when the door is closed, if a distance detector arranged on an outer panel of the intelligent door lock detects a human body reflection signal, the user is judged to be outside the door, and if the human body reflection signal is not detected, the user is judged to be inside the door. And vice versa.

Further, a human body sensor can be respectively arranged in the door and outside the door to detect whether a user closing the door is in the door or outside the door. The human body sensors arranged in the door and outside the door can be arranged in a mixed mode, for example, a human body infrared sensor is arranged outside the door, and a camera is arranged in the door.

The processing controller triggers the reminder to send out non-locking reminding information such as continuous buzzing according to the fact that the second sensor does not detect the locking signal, and controls the reminder to change to send out the locking reminding information such as continuous buzzing to be changed into one-time ringing of the bell and then stop reminding when the second sensor detects the locking signal.

And if the processing controller analyzes and judges that the user is far away from the door lock according to the detection information of the non-contact human body sensor, the reminder is controlled to stop sending out reminding information. For example, the signal intensity of the mobile terminal detected by the wireless communication module is greater than a set threshold value or the signal disappears, or the user is far away or disappears from a camera shooting area through camera image information recognition, or the user distance detected by the distance detector is greater than the set threshold value or the reflected signal cannot be detected, and the like, the fact that the user is far away from the door lock and exceeds a set reminding range or exceeds the detection range of the human body sensor and cannot hear the reminding information is judged, and the processing controller controls the reminder to stop reminding.

In addition, the reminding system can also be provided with a clock module electrically connected with the processing controller, the processing controller controls the reminder to trigger the clock module to time after sending out reminding information, and if the reminding duration reaches a set time period, such as 5 seconds or 10 seconds, the processing controller controls the reminder to stop reminding.

Further, the system also comprises a network communication module, and the network communication module comprises the Internet of things or the Internet. For example, a WiFi module is arranged in an intelligent camera or an intelligent door lock, if a user is far away from the door lock, the intelligent door lock controls a reminder to stop reminding, and remote reminding information is sent to an intelligent mobile phone associated with the user through network communication.

The utility model discloses a first sensor detects the signal of closing the door, detect the signal of locking through the second sensor, through human body sensor monitoring user's the action of closing the door, no matter be the intelligent lock that locks automatically or the manual intelligent lock that locks, no matter the user door closing process is that the length is short or the speed of closing the door is fast slow, close the door action end or turn over leave information as control node to the user that human body sensor detected, if go wrong or appear false lock, change according to human body sensor's detection information, hold the best warning opportunity, break away from the lock handle at the user hand, or close the door action and end, or turn over and remind when leaving the lock, avoid causing the warning delay, or remind premature phenomenon.
