[0017] With the rapid development of the smart home industry, smart locks and smart doors, as important carriers of home security and convenient life, their remote control and sensing unlocking technology have become a research and development hotspot. Among them, remote sensing technology, which can realize signal transmission and control without physical contact, is widely used in the field of smart locks. In particular, Bluetooth technology is often used as the core communication method for remote sensing unlocking due to its low power consumption and strong compatibility. The basic principle of the existing smart lock unlocking scheme based on Bluetooth technology is usually to transmit a Bluetooth signal by a transmitter (such as a mobile phone), and then the Bluetooth receiving module on the smart lock receives the signal and transmits it to the micro control unit (MCU). The MCU controls the door lock to perform corresponding actions according to the relevant parameters of the signal (judges whether the unlocking condition is met, and then controls the door lock to perform corresponding actions, so as to realize the complete control process from signal reception to instruction execution.

[0018] However, the Bluetooth remote sensing unlocking technology in the related art still has many problems to be solved in practical application.

[0019] In one aspect, the related Bluetooth transmission and reception are mostly in 360-degree omnidirectional mode, which is a signal transmission method without direction restriction and is extremely easy to cause misoperation risk in a fully automatic induction scene. For example, when the user places the mobile phone indoors, the continuously transmitted Bluetooth signal of the mobile phone may be captured by the receiving module of the smart lock. If the system does not effectively distinguish the location of the signal source, it will misjudge that the user triggers the unlocking outside, thereby executing the automatic unlocking action. This not only violates the basic requirement of the user for the safety of the door lock, but also may cause potential safety hazards.

[0020] On the other hand, in order to achieve accurate positioning of the transmitter, the related technology often relies on multiple receiving slaves cooperating with a master receiver, or uses the phase difference of the received signal to position through multiple antennas at different positions. The former needs to deploy multiple receiving devices, which not only increases the hardware cost, but also is limited by the space conditions of the installation of the smart lock. The latter has extremely high requirements for the antenna layout and the calculation accuracy of the signal phase difference, and is easy to have positioning deviation in complex environments (such as wall shielding and electromagnetic interference), which affects the reliability and stability of the unlocking.

[0021] In order to solve the above problems, the present disclosure provides a differential positioning directional anti-misoperation remote sensing smart door lock device, which comprises: an outdoor antenna installed on one side of the smart door lock located outdoors, which is a directional antenna for receiving radio frequency signals from the transmitting end within a preset effective range of the outdoor environment; an indoor antenna installed on one side of the smart door lock located indoors, for receiving radio frequency signals from the transmitting end within the full range of the indoor environment; a Bluetooth receiving module connected to the outdoor antenna and the indoor antenna, for extracting the outdoor signal strength value and the indoor signal strength value and sending them to the MCU; a PCBA control board containing the MCU, configured to perform the following steps: calculating the real-time difference between the outdoor signal strength value and the indoor signal strength value; when the real-time difference is greater than a preset threshold, determining that the transmitting end is located outdoors; when the real-time difference is less than the preset threshold, determining that the transmitting end is located indoors; when the transmitting end is located outdoors and the transmitting end is within the preset effective range, issuing an unlocking instruction; and a door lock motor for executing the unlocking action of the smart door lock according to the unlocking instruction.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0023] Please refer to Figure 1 ,Figure 1 is an exemplary schematic diagram of an architecture of a differential positioning directional anti-mis-touch remote sensing intelligent door lock device according to an embodiment of the present disclosure. As shown in Figure 1 the differential positioning directional anti-mis-touch remote sensing intelligent door lock device 100 includes an outdoor antenna 101, an indoor antenna 102, a Bluetooth receiving module 103, a PCBA control board 104, and a door lock motor 105, wherein:

[0024] The outdoor antenna 101 is installed on the side of the intelligent door lock located outdoors and is a directional antenna for receiving radio frequency signals from the transmitting end within a preset effective range of the outdoor environment.

[0025] In this embodiment, the door on which the intelligent door lock is installed is used to distinguish between indoor and outdoor environments; the intelligent door lock installed on the door is divided into a side located outdoors and a side located indoors. Among them, the outdoor antenna 101 is installed on the side of the intelligent door lock located outdoors and is used to receive radio frequency signals located outdoors.

[0026] The outdoor antenna 101 is a directional antenna, that is, an antenna that can only effectively receive signals within a specific preset effective range outdoors, and signals beyond the preset effective range cannot be effectively received.

[0027] Here, the radio frequency signals are continuously sent by the transmitting end in a broadcast manner to ensure that the outdoor antenna 101 can stably and timely receive the signals.

[0028] By way of example, the transmitting end can be a smart mobile terminal, for example, the transmitting end can include but is not limited to: a mobile phone, a tablet computer, a smart watch, etc.

[0029] Further, the preset effective range is the radio frequency signal receiving range set by the household in advance, which can be set according to actual application requirements.

[0030] The indoor antenna 102 is installed on the side of the intelligent door lock located indoors and is used to receive radio frequency signals from the transmitting end within the full range of the indoor environment.

[0031] In this embodiment, the indoor antenna 102 is an omnidirectional antenna, and the signal receiving range has no angle limitation and can cover the entire indoor area, that is, the indoor antenna 102 can be used to receive radio frequency signals from the transmitting end located at any position in the indoor environment in a 360-degree omnidirectional manner.

[0032] The Bluetooth receiving module 103 is connected to the outdoor antenna and the indoor antenna at the same time and is used to extract the outdoor signal strength value and the indoor signal strength value and send them to the MCU.

[0033] In the embodiment, the Bluetooth receiving module 103 is configured to simultaneously receive the radio frequency signal of the transmitting end from the outdoor antenna 101 and receive the radio frequency signal of the transmitting end from the indoor antenna 102, and determine the outdoor signal strength value and the indoor signal strength value, and send the extracted two signal strength values (Received Signal Strength Indicator, RSSI) to the MCU as the data basis for the MCU to determine the position of the transmitting end.

[0034] Specifically, the Bluetooth receiving module 103 simultaneously includes a master Bluetooth receiving module 1031 and a slave Bluetooth receiving module 1032, and the functions of the master receiver and the slave receiver can be realized in a single module, so that it is not necessary to additionally set up multiple independent receiving modules, thereby reducing the cost and reducing the space limitation.

[0035] The PCBA control board 104 contains the MCU, which is configured to perform the following steps: calculating the real-time difference value of the outdoor signal strength value and the indoor signal strength value; when the real-time difference value is greater than a preset threshold, determining that the transmitting end is located outdoors; when the real-time difference value is less than the preset threshold, determining that the transmitting end is located indoors; when the transmitting end is located outdoors and the transmitting end is within a preset effective range, issuing an unlocking instruction.

[0036] In the embodiment, the MCU contained in the PCBA control board is the control center of the system, which is used to execute the preset program to complete the determination of the position of the transmitting end and the triggering of the unlocking instruction.

[0037] Specifically, the MCU is configured to execute the following preset program: receiving the outdoor signal strength value and the indoor signal strength value of the Bluetooth receiving module 103 in real time, calculating the real-time difference value; when the real-time difference value is greater than a preset threshold, determining that the transmitting end is located outdoors; when the real-time difference value is less than the preset threshold, determining that the transmitting end is located indoors.

[0038] Here, when it is determined that the transmitting end is located indoors, it means that the resident is located indoors, and at this time the user does not need to open the door, so the unlocking instruction is not triggered, thereby preventing the door lock from being unlocked by mistake.

[0039] Further, when it is determined that the transmitting end is located outdoors and within a preset effective range, it means that the resident is within a specific angle and distance range in front of the smart door lock and has the intention to unlock and enter, and at this time the unlocking instruction is triggered to automatically unlock the door for the resident, so that the user can enter the indoor without manually unlocking, thereby greatly improving the boundary degree of the user entering the indoor.

[0040] Further, the PCBA control board 104 can be powered by a Low Dropout (LDO) power supply. Here, the LDO power supply can be 3.3V.

[0041] The door lock motor 105 is used to execute the unlocking action of the smart door lock according to the unlocking instruction.

[0042] In this embodiment, the door lock motor 105, as the actuator of the unlocking action of the smart door lock, drives the retracting of the lock tongue or the unlocking of the lock body of the smart door lock through its mechanical transmission structure (such as gears, connecting rods, and other auxiliary mechanisms) after receiving the unlocking instruction, to complete the physical unlocking action.

[0043] Further, the door lock motor 105 can be powered by an 8.4V battery.

[0044] The directional anti-misoperation remote sensing smart door lock device and the remote sensing unlocking method according to the above embodiments of the present disclosure use a directional receiving design through an outdoor antenna, receive only outdoor signals within a preset effective range, and ensure that the unlocking can be triggered only when the transmitting end is in a specific area directly in front of the outdoor environment, thereby avoiding the problem of mistaken unlocking and improving the safety of the door lock. The use of one Bluetooth receiving module and two antennas greatly reduces the number of hardware and production costs. Meanwhile, the compact structure design avoids the space limitation of multiple device installation, and is particularly suitable for application scenarios of small-sized products such as smart locks and smart doors. Through the angle and distance limitation of the directional antenna and the real-time signal difference judgment, it is ensured that the door lock can be automatically unlocked only when the resident is in a specific area directly in front of the outdoor environment, which not only meets the convenience of hands-free operation, but also ensures the reliability and safety of the unlocking action through precise positioning.

[0045] In one possible implementation of the above embodiment, the outdoor antenna 101 is a horn-shaped directional antenna receiving device, which is used to receive radio frequency signals from the transmitting end in a specific area within a preset angle and a preset distance in the outdoor environment as a preset effective range.

[0046] In this embodiment, the outdoor antenna 101 is a horn-shaped directional antenna receiving device, and its physical structure determines the directional characteristics of signal reception, which is used to receive radio frequency signals within a preset effective range.

[0047] Here, the horn-shaped directional antenna design divides the area within a preset angle and a preset distance in the outdoor environment as a preset effective range. Among them, the preset angle is the directional receiving angle range of the horn-shaped outdoor antenna 101, and signals beyond this angle range will be naturally attenuated by the antenna structure of the outdoor antenna 101 and cannot be effectively received.

[0048] The preset distance can be pre-set according to actual needs, for example, the preset distance can be set to within 5 meters, and signals beyond this distance cannot be effectively identified due to insufficient strength.

[0049] Please refer to Figure 2, Figure 2 is a preset effective range schematic diagram of a differential positioning directional anti-mis-touch remote sensing intelligent door lock device according to an embodiment of the present disclosure. As shown in Figure 2 , the A area represents a non-effective range; the B area represents a preset effective range corresponding to the horn-shaped directional antenna receiving device as the outdoor antenna 101.

[0050] Through the differential positioning directional anti-mis-touch remote sensing intelligent door lock device and the remote sensing unlocking method according to the above embodiments of the present disclosure, the horn-shaped directional antenna naturally forms a preset effective range with a preset angle and a preset distance through the physical structure, and only receives the radio frequency signals in the range. Signals beyond the preset angle are attenuated by the antenna structure, and signals beyond the preset distance cannot be identified due to insufficient strength, which limits the spatial range that can trigger the unlocking from the hardware level, and solves the problem of mis-unlocking caused by the signal boundary of the 360-degree omnidirectional antenna. The horn-shaped directional antenna realizes directional reception through its own structure, and can complete the positioning of the outdoor effective area of the transmitting end by combining with the signal difference value of the indoor omnidirectional antenna, without the need for additional receiving equipment, reducing hardware costs and installation space limitations.

[0051] In one possible implementation of the above embodiment, microwave absorbing materials are arranged at both sides of the outdoor antenna 101, for attenuating radio frequency signals in the side area outside the preset effective range in the outdoor environment.

[0052] In the present embodiment, the microwave absorbing materials are installed at both sides of the outdoor antenna 101, for attenuating radio frequency signals in the side area outside the preset effective range in the outdoor environment.

[0053] Specifically, the microwave absorbing materials are used to attenuate radio frequency signals emitted by the side area outside the preset effective range, and radio frequency signals propagated to the side area after the indoor transmitting end signals are reflected by glass and objects.

[0054] Exemplarily, the microwave absorbing materials can be, but are not limited to, ferrite wave-absorbing materials, carbon fiber composite materials, etc.

[0055] Further, the microwave absorbing materials can be installed at both sides of the outdoor antenna 101 by means of bonding or embedding, etc.

[0056] The directional anti-mis-touch remote sensing intelligent door lock device and the remote sensing unlocking method through differential positioning of the above-mentioned embodiments of the present disclosure further weaken the strength of these non-target signals through the absorption characteristics of the microwave absorbing material to the microwave signals, so that they cannot be effectively received by the outdoor antenna 101, reducing signal interference from the source. The microwave absorbing material attenuates the signals reflected to the side area, and cooperates with the directional receiving characteristics of the outdoor antenna itself, double-ensuring that indoor signals cannot trigger unlocking even if they are reflected, completely avoiding the problem of indoor misoperation. The structure attenuation of the microwave absorbing material and the horn-shaped directional antenna are complementary, further clearly defining the signal boundary between the preset effective range and the non-effective range. After the signals in the side area are effectively weakened, the outdoor antenna 101 can only stably receive the target signals within the preset angle and distance, ensuring that the MCU judges the position of the transmitting end more accurately, reducing the misjudgment caused by signal mixing, and improving the reliability of the overall operation of the intelligent lock.

[0057] In one possible implementation of the above-mentioned embodiments, the transmitting end is a mobile phone, which transmits a radio frequency signal with a preset registration identification code through broadcasting; the Bluetooth receiving module 103 is configured to only respond to the radio frequency signal containing the preset registration identification code, and ignore the unregistered radio frequency signal.

[0058] In the present embodiment, the preset registration identification code is generated by the householder through the operation interface of the intelligent door lock, and corresponds to the mobile phone as the transmitting end one by one, and is used to identify the mobile phone as an authorized device.

[0059] The Bluetooth receiving module 103 is configured to directly ignore the radio frequency signal that does not contain the preset registration identification code (i.e. the signal transmitted by the unregistered mobile phone), and does not extract the signal strength value and subsequent processing.

[0060] Through the differential positioning directional anti-mis-touch remote sensing intelligent door lock device and the remote sensing unlocking method of the above-mentioned embodiments of the present disclosure, the preset registration identification code corresponds to the mobile phone one by one, and is generated by the householder through the operation interface, only the authorized mobile phone can transmit a radio frequency signal containing the identification code. The Bluetooth receiving module 103 only responds to the signal containing the identification code, and directly ignores the signal of the unregistered device, which prevents non-authorized devices (such as other people's mobile phones) from triggering unlocking by transmitting radio frequency signals from the source, ensuring that the intelligent lock only responds to the householder's authorized mobile phone, greatly improving the security. The householder can complete the binding of the mobile phone and the registration identification code through the operation interface without complex settings; and the automatic filtering mechanism of the Bluetooth receiving module does not require human intervention, which ensures that only authorized devices can trigger unlocking while not affecting the full-automatic induction unlocking experience of the authorized mobile phone within the effective range, achieving a balance between security and convenience.

[0061] Further reference is made to Figure 3 , Figure 3is a flowchart of a remote sensing unlocking method provided by the embodiments of the present disclosure, which is applied to the above-mentioned Figure 3 As shown in the directional anti-mis-touch remote sensing intelligent door lock device 100 of differential positioning, the flow of the method can include the following steps:

[0062] In step S301, the transmitting end and the Bluetooth receiving module are pre-configured through the operation interface of the intelligent door lock, so that the Bluetooth receiving module only responds to the radio frequency signal containing the preset registration identification code, and the preset angle and the preset distance included in the preset effective range outdoors are configured.

[0063] In step S302, the transmitting end continuously transmits the radio frequency signal with the preset registration identification code in a broadcast manner.

[0064] In step S303, the radio frequency signal is received in the preset effective range outdoors through the outdoor antenna, and an outdoor signal is generated.

[0065] In step S304, the radio frequency signal is received indoors through the indoor antenna, and an indoor signal is generated.

[0066] In step S305, the Bluetooth receiving signal is used to extract the strength value of the outdoor signal and the strength value of the indoor signal, and the two sets of strength values are sent to the MCU in real time.

[0067] In step S306, the real-time difference value between the outdoor signal strength value and the indoor signal strength value is calculated through the PCBA control board containing the MCU, when the real-time difference value is greater than the preset threshold, it is determined that the transmitting end is located outdoors; when the real-time difference value is less than the preset threshold, it is determined that the transmitting end is located indoors.

[0068] In step S307, when it is determined that the transmitting end is located outdoors, and the radio frequency signal is received by the outdoor antenna within the preset effective range, the MCU controls the door lock motor to perform the unlocking action of the intelligent door lock.

[0069] In this embodiment, the preset threshold can be 0, when the real-time difference value is greater than 0, it indicates that the transmitting end is located outdoors; when the real-time difference value is less than 0, it indicates that the transmitting end is located indoors.
