Description

Door lock opening control method and system based on active security

Technical Field

The invention relates to the field of door locks, in particular to a door lock opening control method and a door lock opening control system based on active security.

Background

The door lock is a security device, but the traditional door lock, no matter a mechanical lock, a fingerprint lock, an IC card lock and the like, belongs to a passive management door lock, namely, the door lock and the environment inside and outside the door lock can not be actively monitored and managed. 10/2013, with the application number of 201310471169.0 named as "an active security entrance guard control method and a control system thereof", a system with an active security function is provided, which comprises a detection module, an alarm device and a relay for connecting the detection module and the alarm device; the detection module comprises a radar and a judgment device connected with the radar, the radar is connected with a power supply, the radar is used for detecting outdoor conditions in a detection range in real time, when people or objects are in the detection range, the judgment device immediately carries out logic judgment, the judgment device judges whether the objects trigger a doorbell system, and if yes, circulation is ended; otherwise, executing step S30; when the judgment result is that the inverter is not on, sending an electric signal to the input end of the relay; the relay is used for attracting and connecting the circuit to supply power for the alarm device after receiving the electric signal sent by the detection module; the alarm device is used for alarming after the power supply is switched on.

It can be known from the description in paragraph 0025 of the ZL201310471169.0 patent specification that the control core is to implement classification logic judgment on the movement track of a person who attempts to drive the doorbell system by a doorbell close to a front of a door, especially a front of a door, by using a detector and a logic algorithm, so as to determine whether to activate an alarm function, wherein the main classification logic given by the patent is the key logic judgment points such as the distance of the person or object to the door lock and the length of time of staying outside the door, for example, the distance of the moving object to the control system defined in claim 1, the first preset time period, the second preset time period, the alarm threshold, and the like. However, the behavior of the person who really has the intention of destruction is usually prepared or has multiple ends, and various possibilities cannot be included only by a limited number of judgment logic elements, such as unlocking by a person who steals an unlocking instruction, accessing a door lock by shielding a radar signal, accessing a front fly or starting a doorbell by adopting a multiple fraud signal mode, or directly unlocking by adopting violence; secondly, the control system for setting logic operation has difficulty in setting and debugging the accuracy of the control logic, for example, the optimal setting of the alarm threshold value is uncertain, because the alarm threshold value of the patent is a reference value for judging the intensity degree of a radar transmission signal and further determining whether to start the alarm action, namely, the alarm threshold value is a radar signal value with certain intensity, the size of a radar reflection signal is not only related to the distance between a moving object and a door lock, but also related to the external shape (the size of a reflection surface) of the moving object and the characteristics of a surface material (whether to absorb the radar signal), one reference value (threshold value) is far from meeting the actual environment requirements of various fields (namely, although the environment in a laboratory is feasible, the deviation occurs in various actually applied environments, and at least the wall decoration materials adopted in each different environment are different, the strength of the reflected signal is different), while the signal strength caused by the distance is only used as a judgment reference in the patent, the radar technology is obviously very inaccurate, and the alarm threshold value selection of the patent is basically impossible to realize or has practicability and is influenced by too many environmental factors. Secondly, the distance between the door bell system and the front fly and the length of the stay time outside the door cannot become the basic standard for judging whether the person is good or bad, which is not feasible in law. Therefore, the security effectiveness of the active security method and the control system thereof is obviously insufficient and even difficult to apply, and further improvement of the active security system is obviously necessary. Secondly, frequent alarming not only hinders normal life but also causes the electric energy consumption of the front fly to be very large, and the frequent alarming is almost an unusable scheme for door locks such as a door lock which adopts a door leaf and adopts a dry battery for power supply.

Disclosure of Invention

According to the defects of the prior art, the inventor provides a new idea and scheme for realizing the door lock opening control method and the door lock opening control system based on active security, so that the door lock opening control method and the door lock opening control system are simple, intelligent and convenient to use, and the specific conception is as follows:

1. the method has the advantages that complex logic operation methods such as time, threshold values and the like in the prior art are abandoned, attention is paid to door lock operation behaviors, namely whether a person unlocks and destroys the door lock or does not close the door leaf in time, whether a moving object approaches the door lock or stays beside the door leaf or whether the moving mode, the track and the stay time of the moving object are not considered in a key mode, and in management logic, one logic parameter of whether the moving object exists is mainly selected; for a moving object which approaches a door lock but does not perform abnormal door lock opening action, the unnecessary burden of a door lock manager can be increased by monitoring and recording the information of the moving object regularly but not necessarily adopting an extremely violent management means such as an alarm.

2. Considering that the door lock is mainly used for an indoor or a gate and is not a passage with very large people flow, on the basis of reasonably setting a detection range (such as 0.2-2 meters) from the angle of hardware, any moving people or objects in the detection range are directly recorded and stored without paying attention to the running track mode of the door lock and complex logic judgment and operation, and can further upload a feedback signal to a network for future reference, and upload the feedback signal to an alarm, send prompt information and the like when abnormal unlocking, lock damage or door leaf non-closing behaviors occur. Therefore, for any moving person or object, the security measures are implemented when the door lock is approached, no time dead angle is left, the management is simple, complex logic judgment and algorithm in the prior art, such as threshold setting and time setting, are omitted, and the control precision is high.

3. The mode of breaking the normal management order of the door lock to enter the room is various, wherein the mode mainly comprises violent unlocking, holding the family to unlock and technical unlocking (unlocking by a high-hand lock key but adopting a technical method), therefore, the control on the unlocking modes not only can improve the recourse and monitoring performance of the unlocking modes, but also meets the modern intelligent life requirement.

4. The operation of unlocking is monitored in multiple dimensions, such as sound, image and fingerprint picking and recording, and the content can be transmitted and recorded in real time, so that the traceability of personnel entering the room by using the door lock can be further improved.

According to the technical idea, the invention provides a door lock opening control method based on active security, the door lock comprises a central controller, a moving target detector, an unlocking instruction pickup device, a camera device, a wireless networking device and a locking control mechanism, wherein the moving target detector is used for transmitting detection signals and receiving detection signals reflected by objects in a space outside the lock and transmitting feedback signals corresponding to the received reflection detection signals to the central controller, the unlocking instruction pickup device is used for picking up unlocking instructions and transmitting unlocking signals corresponding to the unlocking instructions to the central controller, the camera device is used for shooting scenes outside the door and transmitting shot pictures or images to the central controller, the wireless networking device is used for realizing information exchange between the central controller and an external network, the locking control mechanism is used for enabling the door lock to be unlocked under the control of the central controller; the method is characterized by comprising the following steps:

step 4, on the basis of the step 1, if it is determined that the moving object has entered the detection range of the moving object detector but the moving object does not leave the detection range of the moving object detector within a set first time period but any trigger action including triggering the unlocking instruction pickup device is not performed, starting the camera device within a set second time period after the first time period;

step 5, on the basis of the step 4, if the mobile object does not perform any triggering action including triggering the unlocking instruction pickup device within the second time period and leaves the detection range of the mobile object detector, returning to the detection state;

step 6, on the basis of the step 4, if the mobile object does not leave the detection range of the mobile object detector in the second time period and the normal unlocking action is implemented, the camera device takes a picture; if the central controller verifies that the command belongs to an authorized unlocking command, the locking control mechanism is opened, and the locking control mechanism returns to a detection state after being opened;

step 7, on the basis of the step 4, if the mobile object does not leave the detection range of the mobile object detector in the second time period but does not perform any triggering action including triggering the unlocking instruction pickup device, the camera device starts to shoot after the second time period;

step 8, on the basis of the step 7, if a normal unlocking action is implemented after the second time period and the unlocking action is later than the shooting time started by the shooting device in the step 7, the shooting device is started again and shoots; if the central controller verifies that the command belongs to an authorized unlocking command, the locking control mechanism is opened, and the locking control mechanism returns to a detection state after being opened;

and 9, on the basis of the step 7, if the moving animal does not leave the detection range of the moving target detector after the second time period but does not perform any triggering action including triggering the unlocking instruction pickup device all the time, after the shooting of the camera device is finished, returning to the detection state.

Correspondingly, the invention also provides a door lock control system based on active security, which comprises a moving target detector, a central controller, an unlocking instruction pickup device, a camera device, a wireless networking device and a locking control mechanism, wherein the moving target detector, the central controller, the unlocking instruction pickup device, the camera device, the wireless networking device and the locking control mechanism are arranged on a door lock; the method is characterized in that:

the moving target detector is used for transmitting a detection signal, receiving the detection signal reflected by an object in the space outside the lock and transmitting a feedback signal corresponding to the received reflected detection signal to the detector management module, and when a moving object appears in the detection range set by the moving target detector, the moving target detector transmits the feedback signal corresponding to the moving object to the detector management module;

the unlocking instruction pickup device is used for picking up an external unlocking instruction and transmitting an unlocking signal corresponding to the unlocking instruction management module; the unlocking instruction management module is used for verifying an unlocking instruction and controlling to open the locking control mechanism after verifying that the unlocking instruction belongs to an authorized unlocking instruction;

the camera shooting device is used for shooting pictures or dynamic images of outdoor scenes and transmitting the shot pictures or images to the camera shooting management module; the camera shooting management module is used for starting the camera shooting device when the moving object detector detects a moving object and the moving object does not leave or implement any triggering action comprising triggering the unlocking instruction picking device within a set first time period, and controlling the camera shooting device to shoot when the moving object does not leave or implement any triggering action comprising triggering the unlocking instruction picking device within a set second time period; the camera shooting management module is also used for starting the camera shooting device to shoot when an unlocking instruction is received or an external network sends an environment query instruction to the door lock;

the wireless networking device is used for realizing real-time information exchange between the central controller and external network signals;

the locking control mechanism is used for acting under the control of the locking control management module to enable the door lock to be unlocked when an authorized unlocking instruction is received or an external network sends an unlocking instruction to the door lock.

Wherein the moving object detector is a detector capable of automatically transceiving a detection signal such as infrared or microwave so as to detect a moving object in front of the detector. Any moving object, such as a person or a moving object (collectively referred to herein as a mover), that is close to the door lock can be found by the moving object detector. The detection distance of the moving target detector is generally set to be 0.2 to 2 meters away from the lock, and the specific range can be adjusted according to the use type of the door lock. Secondly, the transmitted signal can be continuous or intermittent, in order to reduce the energy consumption of the door lock, the invention adopts an intermittent detection mode, the interval time can be between 10 milliseconds and 200 milliseconds, and the energy consumption can be greatly saved by adopting an intermittent detection technology. In addition, the intensity of the detection signal may be gradual, that is, the signal intensity is the lowest and the time interval is the longest in the standby mode (also referred to as the detection mode), and when the moving object is found by the initial detection, the signal intensity is properly increased or the detection frequency is encrypted so as to improve the accuracy of determining whether the moving object exists.

The central controller is a control center of the door lock, and comprises various functional modules, an operation center and a memory, wherein the functional modules, the operation center and the memory are mentioned in the text, so that the central controller not only can receive signals transmitted by various sensors, but also can receive various instructions given by an external network, and can upload various sensing information to the external network and terminal equipment thereof, such as a computer, a mobile phone or an APP (application) in real time. The central controller may be an integrated controller or a general term for controllers which are distributed corresponding to the respective controlled functional units but have information communication with each other, so that when one of the functional units is controlled to operate, the other functional units may be in a sleep state.

The unlocking instruction pickup device is a device capable of picking up an unlocking instruction, such as a fingerprint detection head capable of picking up a fingerprint signal, a sensor capable of picking up an IC card signal, a sound control sensor capable of picking up a sound instruction signal, a facial makeup recognizer capable of picking up a facial makeup signal, an induction device capable of picking up a key unlocking signal, or/and a door lock vibration induction device capable of picking up a vibration signal caused by destructive unlocking, and the like, wherein the unlocking instruction pickup device picks up a related unlocking instruction signal, arranges the signal and transmits the signal to the central controller. Generally, for different signal characteristics, corresponding and different sensors or detectors are required to be arranged on the door lock to respectively monitor and pick up different signals. It should be noted that the unlocking instruction pickup device picks up the unlocking instruction is only one way of unlocking, and actually, the unlocking instruction can be sent to the central controller through the APP in the external network to directly unlock the door lock, so that when a visitor comes from a foreign country, for example, the door can be directly opened through remote operation without physically returning to home to open the door.

The normal unlocking command is a start command action performed to achieve normal unlocking, and for example, when the unlocking command pickup device has a start button or a proximity sensor, the start button or the proximity sensor is triggered to operate. The unlocking instruction pickup device has different structural types, and the starting mode can be different. Therefore, the normal unlocking instruction refers to an unlocking instruction for unlocking by authorized personnel such as family members in a normal mode, and the normal unlocking instruction comprises direct normal unlocking or network remote instruction normal unlocking. The normal unlocking instruction in which the authorized person unlocks in a normal manner is determined as an erroneous instruction because an input error is not always acceptable, and thus repeated verification is required, for example, in the case of fingerprint identification, since the finger is placed too far, the finger is not recognized successfully. Therefore, the authorized unlocking instruction can be verified to pass, and otherwise, the unauthorized unlocking instruction is verified to belong to. The authorized unlocking command includes a hijacking unlocking command, which will be described below.

In the technical scheme including the step 2, the technical feature that "any triggering action including triggering the unlocking instruction pickup device is not implemented" is included, and the feature defines two aspects, one aspect is that the triggered object includes but is not limited to the unlocking instruction pickup device, and can also be a doorbell, a special starting key, a voice control sensor and the like, and the other aspect is "triggering", and includes both directly triggering the starting action such as pressing a key and indirectly triggering whether the starting action exists or not such as non-contact sensing through a position sensor, and non-contact identifying the door opening voice action and the instruction thereof through the voice control sensor and the like.

The locking control mechanism can be an electric control device which can directly drive a lock tongue piece which plays a locking function to act, and can also be a driving piece of a handle clutch in the door lock.

The external network not only refers to the internet, but also refers to a fixed terminal or a mobile terminal connected with the internet, an operating APP controller and the like.

The first time period and the second time period are preset time periods, the first time period is set, the camera device is started after the set first time period is over, most of moving objects which are in the detection range of the moving target detector and are mistakenly intruded can be filtered, and therefore the frequency of starting the camera device is greatly reduced, such as passing neighbors or playing children. The second time period is set mainly for setting a sufficient start time for the image pickup apparatus (generally, the start time of the image pickup apparatus is between 1 second and 5 seconds, and image pickup can be performed after the start), and for filtering out the outside mistaken entry person again. The length of the first time period is set, and is also related to the detection distance set by the moving object detector, and if the detection distance is long, the set length of the first time period may be longer. In practice we generally set the first period of time between 3 seconds and 10 seconds and the second period of time between 1 second and 5 seconds.

The detection state mainly means that except for the moving target detector and a central control module for driving the moving target detector to work, other energy consumption components are in a dormant state as much as possible, so that energy consumption is saved as much as possible, but not all other electric devices do not work, for example, a power indicator lamp can be in a light-emitting state all the time, a proximity sensor and a voice control sensor for sensing whether a starting action exists can be in working all the time, and the proximity sensor and the voice control sensor can also be in working under the condition that a key is started. Therefore, when in the detection state, the central controller preferably controls the unlocking instruction pickup device, the camera device and the wireless networking device to be in the dormant state, so that the energy consumption is saved as much as possible, and the service life of the product can be prolonged.

According to the technical scheme, compared with the prior art, the intelligent door lock has the beneficial technical effects that any moving object and normal unlocking action within the detection range can be found on the basis of reasonably setting the detection range from the angle of hardware, invalid moving object signals are filtered by adopting the time period without complex logic operation, energy consumption is saved, misoperation can be greatly reduced, and safety can be guaranteed, and the intelligent door lock can not become an annoying thing for frequent alarming.

The further technical scheme can also be that if the central controller verifies that the command belongs to an unauthorized unlocking command and still cannot be verified within verification delay time, the locking control mechanism cannot be started, and after the verification delay is finished, the door lock enters a detection state.

The further technical scheme can also be that after the central controller verifies that the time delay is finished, the normal unlocking instruction management module of the central controller enters a dormant state, and the normal unlocking instruction management module can be waken up after the time delay is carried out for the third time period again. The third time period is set to filter out the human-induced interference trigger action. The third time period is generally about 3 minutes.

The further technical scheme can also be that the unlocking instruction is divided into a normal unlocking instruction and an abnormal unlocking instruction, wherein the abnormal unlocking instruction comprises a hijack unlocking instruction or/and a destructive unlocking instruction; when the central controller receives an abnormal unlocking instruction, the camera device is started and shoots, and an alarm signal is synchronously transmitted to an external network through the wireless networking device. Correspondingly, in the door lock control system, the unlocking instruction management module comprises a normal unlocking instruction management module and an abnormal unlocking instruction management module, and the abnormal unlocking instruction management module comprises a hijack unlocking instruction management module or/and a destructive unlocking instruction management module; and the abnormal unlocking instruction management module is used for starting the camera device to pick up the image and transmitting the picture to an external network through the wireless networking device after receiving the abnormal unlocking information, and transmitting an alarm signal to the external network through the wireless networking device.

The abnormal unlocking instruction is defined relative to the normal unlocking instruction, and comprises a hijacking unlocking instruction or/and a destructive unlocking instruction.

The hijacking unlocking instruction is a crisis use management instruction which is preset in the central controller in advance (for example, in a door lock adopting fingerprint management, the fingerprint of the right index finger can be input as a normal unlocking fingerprint, the fingerprint of the right middle finger can be input as a crisis use fingerprint in advance; for example, a string of key numbers used by a crisis, a sentence of special language such as 'tired today' and the like are set in advance); normally, a crisis instruction used under the crisis control condition is preset in the central controller in advance, the crisis instruction is only known by a setter or relatives but unknown by others, when a crisis occurs, a hijacked person can unlock the door without using a normal unlocking instruction but additionally using a preset crisis unlocking instruction to open the door (certainly, the crisis unlocking instruction can also be set as a function incapable of opening the door), although the door can be opened according to the instruction of the hijacker, after receiving the hijacked unlocking instruction, the unlocking instruction picking device transmits a corresponding hijacking signal to an abnormal unlocking instruction management module arranged in the central controller, and after receiving the signal, the abnormal unlocking instruction management module synchronously sends a hijacked unlocking warning signal to an external network in real time, so that a manager, a police or a family can try to rescue a managed object or inquire urgently, but such alarm information is present at a remote location and the bad person is not aware that the central controller has alarmed. When various warnings are given, the camera shooting data of the illegal user can be checked through an external network. For this purpose, the hijacking unlocking instruction can be conveniently used for the central controller to identify and transmit the hijacking behavior, but a special sensor or a pickup device is not necessarily required to be arranged for picking up the hijacking unlocking instruction, for example, a fingerprint pickup head can pick up both a normal unlocking instruction and a hijacking unlocking instruction.

The destructive unlocking instruction is a violent unlocking instruction which directly destroys a mechanical structure of the door lock. In extreme cases, the vandals generally enter the house by means of violence for directly destroying the door lock, such as directly smashing and unlocking the door lock, directly drilling the lock head by using a percussion drill, and the like, and the destructive actions can cause the door lock to be severely vibrated. For this purpose, a door lock vibration sensing device can be arranged in the door lock to pick up the unconventional door lock vibration signal and directly transmit the vibration signal to an abnormal unlocking instruction management module arranged in the central controller; the abnormal unlocking instruction management module receives the signal and then synchronously sends a destructive unlocking warning signal to an external network in real time, so that a management unit, a police or a family can conveniently seek rescue or emergency inquiry, and a manager can comprehensively judge whether the condition of the existing place of the door lock is abnormal or not by means of the destructive unlocking signal and the camera data.

The alarm signal is a special prompt signal, a picture or a short message, an alarm telephone, a flashing signal and the like which can particularly remind people such as a door lock manager, a property manager or a police and the like.

The further technical solution may be that, when the central controller receives an instruction for external inquiry of the outdoor environment through the wireless networking device, the central controller starts the camera device and takes a picture and transmits the taken picture or image to the external network through the wireless networking device, and returns to the detection state after the inquiry is completed or after the central controller opens the locking control mechanism through the external instruction after the inquiry is completed.

The further technical scheme can also be that after the camera device takes the picture, the picture or the dynamic image taken by the camera device is directly stored in the memory of the central controller or/and is transmitted to an external network through the wireless networking device.

The door leaf closing sensing device is used for sensing a signal indicating whether the door leaf is closed in place or not; when the central controller receives a signal that the door leaf is not closed in place through the door leaf closing induction device and does not solve the problem within a reasonable time, the central controller starts a buzzer of the door lock to send out prompt sound or/and transmits an alarm signal that the door leaf is not closed in place to an external network. Correspondingly, in the door lock control system of the further invention, the central controller is also provided with a door leaf closing management module and further comprises a door leaf closing induction device connected with the central controller, and the door leaf closing induction device can sense a signal indicating whether a door leaf is closed in place or not; the door leaf closing management module is used for receiving a door leaf not-closed-in-place signal through the door leaf closing induction device and transmitting a door leaf not-closed-in-place alarm signal to an external network through the wireless networking device when the door leaf not-closed-in-place signal is not solved in reasonable time. The door leaf closing sensing device is a sensing device which can sense whether the door lock is locked and closed when the door leaf is closed or in a virtual state. Such a sensing action is generally not required when the door leaf is fully open. According to the scheme, the door leaf closing sensing device directly transmits the information of whether the door leaf is closed or not to a door leaf closing management module arranged in the central controller; if the door leaf is closed but the door lock is not locked and closed for more than a reasonable time, such as more than 10 seconds, or the door leaf is in a virtual state for more than a reasonable time, such as more than 10 seconds, the door leaf closing management module receives the signal and then synchronously transmits the signal to an external network in real time. The manager can carry out a safety check by means of this signal whether a blocking anomaly is present.

The technical scheme can be that the system further comprises a display device connected with the central controller, when a display button is triggered, the camera device and the display device are started, and the camera device takes a picture and transmits the taken picture or image to the display device. Correspondingly, the door lock control system further comprises a display device connected with the camera shooting management module, and the display device can transmit outdoor scene pictures or dynamic images shot by the camera shooting device to the display device through the camera shooting management module when a display button is triggered. The display button and the starting button for starting the unlocking instruction pickup device can be the same button or can be two separate buttons. Under the condition that the display button and the starting button for starting the unlocking instruction pickup device are the same button, the unlocking action can be synchronous with the shooting and displaying when the display button is started.

The technical scheme is that the system further comprises a sound pickup device and a sound reproduction device which are connected with the central controller, and when the talkback button is triggered, the sound pickup device and the sound reproduction device are started to realize talkback communication. Thus, the sound control and the video control can be combined. Wherein the talk-back button may be integrated with the display button.

The technical scheme is that the device also comprises a detection indicator lamp in signal connection with the central controller, and when the moving object detector detects the moving object target, the light of the detection indicator lamp is on, so that the light of the detection indicator lamp is used for indicating that the moving object detector detects the moving object target.

According to the scheme, the abnormal condition is particularly uploaded to an alarm, alarm type prompt information is sent out and the like. That is, the key point is to manage and control the state of the door lock itself, and for any behavior that does not belong to abnormal unlocking of the door lock, such as a behavior of approaching the door lock, a behavior of not leaving the door lock for a long time, a behavior of triggering a doorbell, or a behavior of normally unlocking the door lock, only a common monitoring measure (recording and saving information) is taken, and an alarm management mode is not necessarily adopted. Therefore, any moving object can be directly monitored as long as the moving object approaches the door lock, no time and dead angle is left, managers cannot be frequently disturbed, complex logic algorithms in the prior art such as threshold setting and time setting are omitted, and control precision is high. Wherein, from the appearance of the moving object to the end of the control process (unlocking the door into the room and closing the door or the passerby leaves), the central controller is always in a working control state, namely, the process of the moving object, the process of unlocking the door, closing the door or destroying the lock is controlled and monitored in the whole process.

The camera device is generally a camera mounted on the outer side plate of the door lock, and the display device can be mounted on the back plate of the door lock or other places in a room. After the camera device is started, the dynamic image situation of the outdoor scene can be visually checked on the display device, and the dynamic situation of the outdoor scene can also be remotely observed through the APP.

The display button is a manual button arranged on a door lock back plate or other indoor places, and outdoor scene dynamic conditions can be observed through the camera device when the display button is manually pressed.

Generally speaking, management module, camera device and display device all can be in the sleep state, but when needs pass through external network for example APP inquiry, when the removal thing appears, when the signal of unblanking appears (including normal unlocking instruction, when robbing the unlocking instruction and appearing the police dispatch newspaper), start the display button, or when the lock is strikeed by the machinery or the striking signal of violent vibrations, just start camera device and display device to not only can record the personnel information who uses the lock, whether the specific user personnel that is convenient for the lock administrator to inquire the lock through long-range mode for example APP belongs to legal authorization personnel or bad person moreover. When the moving object appears in the detection range, the camera management module, the camera device and the display device are not required to be started synchronously, the camera management module, the camera device and the display device can be started after the moving object is detected and determined clearly, and the like, generally, a certain time is needed from the detection of the moving object to the complete determination, and the delay action is set, so that the control management logic is simplified, and the accuracy of judgment can be ensured.

The further technical scheme can also be that after the central controller receives the low-voltage signal, the central controller synchronously transmits a low-voltage alarm signal to an external network. Correspondingly, the intelligent security control system is further characterized in that a low-voltage management module is further arranged in the central controller, and the low-voltage management module is used for synchronously transmitting a low-voltage alarm signal to an external network after the central controller receives the low-voltage signal, so that a user is prompted to replace a power supply battery immediately.

According to the technical scheme and the intentional technical effect thereof, the intelligent door lock can be applied to intelligent door lock products.

The control structure and control logic adopted by the invention are simple, so the corresponding control process is very simple, and the speed, the precision and the reliability of the control operation are greatly improved compared with the prior art. Wherein:

the moving target detector is used for transmitting detection signals, receiving the detection signals reflected by the object in the space outside the lock and transmitting feedback signals corresponding to the received reflection detection signals to the central controller. The moving object detector can automatically transceive a signal such as infrared rays or microwaves so that a moving object in front of the detector can be detected. Any moving object such as a person or a moving object that is constantly in close proximity to the door lock can be found by the moving object detector. The detection distance of the moving target detector is generally set to be 0.2-2 meters away from the lock, such as 0.2 meter, 0.3 meter, 0.5 meter and the like, the specific range can be adjusted according to the use type of the door lock, the detection distance which is too far is large in energy consumption and has no practical significance, and the moving target detector is also a short-distance detector. Secondly, the transmitted signal can be continuous or intermittent, in order to reduce the energy consumption of the door lock, the invention adopts an intermittent detection mode, and the interval time is between 10 milliseconds and 200 millimeters; in addition, the intensity of the detection signal can be gradual, that is, the signal intensity is the lowest in the standby mode, the interval time is the longest, when the moving object is found by initial detection, the signal intensity is properly increased or the detection frequency is encrypted, so that the accuracy of judging whether the moving object exists is improved, and at this time, the situation that whether the moving object needs to be alarmed or not needs to be determined after the moving mode of the moving object is judged first as in the prior art is not needed.

The central controller is a control center of the door lock, comprises various functional modules and an operation center mentioned in the text, and also comprises a memory for storing instruction information and various detection induction information data, can receive, operate and schedule signals transmitted by various sensors, can also receive various instructions given by an external network, and can also upload various sensing information to terminal equipment of the external network such as a computer, a mobile phone or an APP in real time.

The unlocking instruction pickup device is used for picking up an external unlocking instruction and transmitting an unlocking signal corresponding to the unlocking instruction management module; the unlocking instruction management module is used for verifying an unlocking instruction and controlling to open the locking control mechanism after verifying that the unlocking instruction belongs to an authorized unlocking instruction; the unlocking instruction pickup device is a device capable of picking up an unlocking instruction, for example, a fingerprint detection head capable of picking up a fingerprint signal, a sensor capable of picking up an IC card signal, a facial makeup recognizer capable of picking up a facial makeup signal, an induction device capable of picking up a key unlocking signal or/and a door lock vibration induction device capable of picking up a vibration signal caused by destructive unlocking, and the like, and the unlocking instruction pickup device can be normally started by triggering the display button, so that the unlocking instruction pickup device wakes up to be powered on to pick up a related unlocking instruction signal, and transmits the unlocking instruction signal to the central controller after signal processing. Generally, corresponding and different sensors or detectors are required to be arranged on the door lock to respectively monitor and pick up different signals according to different signal characteristics, and different unlocking instructions can be picked up through the same sensor, for example, a fingerprint pickup head or a digital key can be used for picking up a normal unlocking instruction and a hijack unlocking instruction.

If a moving object close to the door lock implements an unlocking instruction close to the door lock, an external unlocking instruction is picked up through the unlocking instruction pickup device and an unlocking signal corresponding to the unlocking instruction is also transmitted to the central controller, and the central controller continues to work and implements corresponding control; aiming at an input unlocking instruction, distinguishing a normal unlocking instruction and an abnormal unlocking instruction and correspondingly making two judgments; when the central controller receives a normal unlocking instruction and verifies that the central controller belongs to an authorized unlocking instruction, the locking control mechanism is opened, otherwise, if the central controller verifies that the central controller belongs to an unauthorized unlocking instruction, the locking control mechanism is not opened; when the central controller receives an abnormal unlocking instruction (abnormal information), the central controller can record and store the abnormal information and synchronously transmit an alarm signal to an external network. The abnormal unlocking instruction mainly comprises a hijacking unlocking instruction, a destructive unlocking instruction and the like.

The hijacking unlocking instruction is a crisis use management instruction which is preset in the central controller in advance (for example, in a door lock adopting fingerprint management, the fingerprint of the right index finger can be input as a normal unlocking fingerprint, and the fingerprint of the right middle finger can be input as a crisis use fingerprint in advance); normally, a crisis command used under the crisis control situation is preset in the central controller in advance, the crisis command is only known by a setter or relatives but unknown by others, when a crisis occurs, a hijacked person can unlock the door without using a normal unlocking command but using a preset crisis unlocking command in addition, although the door can be opened according to the command of the hijacker, after receiving the hijacked unlocking command, the unlocking command picking device transmits a corresponding hijacked signal (abnormal information) to an abnormal unlocking command management module arranged in the central controller, and after receiving the abnormal signal, the abnormal unlocking command management module not only records and stores the abnormal unlocking signal information, but also sends a warning signal of hijacked unlocking to an external network in real time through synchronization, so that a health management unit, a police or a family can try to rescue or inquire urgently, but such alarm messages are present at remote locations and the bad person is not aware that the central controller has sent an alarm message. When various warning messages are sent out, the camera shooting data of the illegal behavior person can be checked through an external network. For this purpose, the hijacking unlocking instruction can be conveniently used for the central controller to identify and transmit the hijacking behavior, but a special sensor or a pickup device is not necessarily required to be arranged for picking up the hijacking unlocking instruction, for example, a fingerprint pickup head can pick up both a normal unlocking instruction and a hijacking unlocking instruction.

The destructive unlocking command is a violent unlocking action which directly destroys a mechanical structure of the door lock. In extreme cases, the vandals enter the house by means of violence which directly damages the door or the door lock, such as directly smashing the door lock, directly drilling the lock head by using a percussion drill, and the like, and the damage actions can cause the door lock to be severely vibrated. For this purpose, a door lock vibration sensing device can be arranged in the door lock to pick up the unconventional door lock vibration signal (abnormal information) and directly transmit the vibration signal to an abnormal unlocking instruction management module arranged in the central controller; after receiving the abnormal signal, the abnormal unlocking instruction management module not only records and stores the abnormal unlocking signal information, but also sends a destructive unlocking warning signal to an external network in a synchronous and real-time manner, so that a management unit, a police or a family can conveniently try to rescue or inquire urgently, and a manager can comprehensively judge whether the condition of the door lock in the place is abnormal or not by means of the destructive unlocking signal and the camera data. The sound management module can be driven to realize pickup and playback talkback functions. Of course, after the mobile object appears and the remote APP obtains the information prompt, the central controller may instruct the remote APP to transmit the shooting and recording information to the APP.

The door lock vibration sensing device is used for sensing a knocking signal of a mechanical knocked door lock or violent vibration of the door lock and transmitting the knocking signal to the abnormal unlocking instruction management module arranged in the central controller, and after the knocking signal is received by the door lock vibration sensing device, the central controller not only records and stores the abnormal signal information, but also synchronously transmits an alarm signal of knocked door lock to an external network.

The door leaf closing sensing device is a sensing device which can sense whether the door lock is locked and closed when the door leaf is closed or in a virtual state. Such a sensing action is generally not required when the door leaf is fully open. According to this solution, if the door leaf is closed but the door lock is not locked closed for more than a reasonable time, for example more than 10 seconds, or if the door leaf is in a virtual state for more than a reasonable time, for example more than 10 seconds, the door leaf closing sensing means directly transmits such a signal to the door leaf closing management module provided in the central controller; the door leaf closing management module receives the signal and then synchronously transmits the signal to an external network in real time. The manager can carry out a safety check by means of this signal whether a blocking anomaly is present.

The camera device is a camera which is generally arranged on an outer side plate of the door lock, and the display device can be arranged on a back plate of the door lock or other places in a room. After the camera device is started, outdoor scene dynamic image conditions can be visually checked on the display device, and the outdoor scene dynamic image conditions can also be remotely observed through an APP. The camera device is used for taking pictures or dynamic images of outdoor scenes and transmitting the taken pictures or image signals to the camera management module; the camera shooting management module is used for starting the camera shooting device when the moving object detector detects a moving object and the moving object does not leave or implement any triggering action comprising triggering the unlocking instruction picking device within a set first time period, and controlling the camera shooting device to shoot when the moving object does not leave or implement any triggering action comprising triggering the unlocking instruction picking device within a set second time period; the camera shooting management module is also used for starting the camera shooting device to shoot when an unlocking instruction is received or an external network sends an environment query instruction to the door lock.

The display button is a manual button arranged on a door lock back plate or other indoor places, and when the display button is manually pressed, outdoor environment conditions can be observed through the display device.

Generally, camera device and display device can be in the sleep state, but when needing to pass through external network for example APP inquiry, when the removal thing appears, when the signal of unblanking appears (including normal unlocking instruction, unusual unlocking instruction appear when reporting an emergency), start to show when pressing the button, or when the lock is strikeed by the machinery or the striking signal of violent vibrations, just start camera device and display device to not only can record the personnel information who uses the lock, be convenient for the lock administrator through the long-range mode for example APP inquiry lock whether the specific user of lock belongs to legal authority personnel or bad person.

The wireless networking device is used for realizing real-time information exchange between the central controller and external network signals; after receiving the moving object signal or the unlocking signal, the central controller further synchronously transmits the signals to an external network through the wireless networking device, or transmits an instruction signal of the external network to the central controller through the wireless networking device, so that the central controller provides relevant information such as whether an outdoor moving object exists, camera shooting and pickup information to the external network.

The doorbell device is used for driving the doorbell management module arranged in the central controller when being triggered, and further can synchronously transmit sound signals to an external network or/and the sound reproduction device. Therefore, the doorbell device provides the function of prompting the visitor request for the visitor, and the information transmitted by the doorbell management module senses the visitor out of the door, and particularly the visitor can be inquired through an external network. For example, after knowing a signal that a person visits, a manager can send an instruction to the central controller in a remote manner through an external network to drive the camera or the voice intercom system to view and inquire the visitor. In the invention, the doorbell device and the display button can be combined into a whole.

Secondly, a low voltage management module is arranged in the central controller, and when the central controller receives a low voltage signal (abnormal information), the central controller synchronously transmits a low voltage alarm signal to an external network, thereby prompting a user to replace a power supply battery immediately. Secondly, since the information collection and storage contents are more, a mode of periodically clearing the information stored in the memory of the central controller or the information stored in the external network can be adopted, and generally, the mode is enough for storing normal information for one day to one month and the mode is enough for storing abnormal information for one year.

That is, for the moving object staying in the space outside the lock, although the staying time exceeds the second time period, if the action of triggering the door lock is not implemented, only the camera is shot, but the alarm signal is not required to be transmitted to the outside.

In the above steps, if the unlocking instruction management module of the central controller verifies that the unlocking instruction belongs to an unauthorized unlocking instruction and still cannot be verified within verification delay time, the locking control mechanism is not started, and after the verification delay is finished, the door lock enters a detection state. Further, after the central controller verifies that the time delay is over, and the normal unlocking instruction management module enters the dormant state, the normal unlocking instruction management module can be waken up after the time delay is performed for a third time period, for example, for about 3 minutes.
