[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0040] It is to be understood that terms such as “first”, “second”, etc. in the present application are only used to distinguish similar objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0041] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0042] It will be understood that “at least one” means one or more, and “plurality” means two or more.

[0043] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0044] Currently, smart door locks based on biometric technology are used, such as face and finger vein recognition door locks. However, the cost of biometric sensor components is higher than that of general communication components, which leads to greater limitations in long-term cost reduction of products. In addition, biometric unlocking technology also requires a lot of calculations and data processing, which requires high processor performance of product equipment, and further increases the application cost. In addition, many users also attach importance to protecting personal biological information and resist using smart door lock products based on biometric recognition technology.

[0045] Compared with biometric authentication unlocking technology, UWB unlocking technology is a low-cost unlocking solution that does not require the collection of biometric features. Currently, based on UWB, it is possible to achieve: 1. High-precision positioning of objects. In the process of unlocking smart door locks, UWB technology can accurately determine the position of the unlocking object by sending and receiving ultra-short pulse signals, so that the door lock can be opened accurately and quickly; 2. The installation of UWB modules is not easily restricted by the material, shape or installation position of the carrier, while the installation of related hardware of biometric technology may have high requirements for identification equipment or installation environment; 3. Compared with traditional Bluetooth or RFID technology (Radio Frequency Identification, radio frequency identification technology), UWB technology has a faster data transmission rate, so that unlocking instructions can be transmitted faster, improving the user's unlocking experience.

[0046] Traditional smart door locks cannot be powered by indoor adapters or power supplies for a long time, and can only be powered by dry batteries or lithium batteries. Since UWB technology requires high energy consumption to achieve accurate positioning and distance measurement of the unlocking object, if smart door locks use UWB technology, the life of the installed batteries may be short. In addition, smart door locks usually need to run for a long time, and frequent replacement of smart door lock batteries will obviously affect the user experience and increase the user's cost of use.

[0047] In order to solve the problem of high power consumption of UWB automatic unlocking technology, the following two solutions are usually adopted: ① Increase the number of dry batteries or the capacity of rechargeable batteries in smart door locks, however, this solution will cause battery pollution. ② Reduce the UWB scanning frequency or reduce the UWB recognition distance, however, this solution to reduce power consumption will also reduce the positioning accuracy and functional stability of the smart door lock UWB, which is equivalent to castrating the performance of UWB, making the original accurate UWB real-time positioning function greatly reduced.

[0048] The door lock opening method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in the figure, Figure 1A smart home system 10 is provided, which includes a terminal device 102, multiple sub-devices 104, a gateway 106, a router 108 and a server 110; wherein the terminal device 102 can be any device with communication and storage functions, and can be but not limited to various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0049] Optionally, a client that can manage multiple sub-devices 104 is installed in the terminal device 102. The client can be an application client (such as a mobile phone APP) or a web client, which is not limited here. As a method, the user can add the same account information to the terminal device 102 and the sub-device 104, and the data of the sub-device 104 and the terminal device 102 can be synchronized through the account.

[0050] The process of multiple sub-devices 104 accessing the gateway 106 through the local area network includes: the gateway 106 first establishes a local area network, and the sub-device 104 joins the local area network established by the gateway 106 by connecting to the gateway 106. This local area network includes but is not limited to: Zigbee or Bluetooth. Among them, the multiple sub-devices 104 can be smart printers, smart fax machines, smart cameras, smart air conditioners, smart door locks, smart lights, or human sensors equipped with communication modules, door and window sensors, temperature and humidity sensors, water immersion sensors, natural gas alarms, smoke alarms, wall switches, wall sockets, wireless switches, wireless wall sticker switches, magic cube controllers, curtain motors, smart speakers, smart doorbells, smart door locks and other devices.

[0051] The interaction between the terminal device 102 and the multiple sub-devices 104 can be achieved through a local area network or a wide area network. In some embodiments, when the terminal device 102, the router 108, and the gateway 106 are in the same local area network, the terminal device 102 can interact with the gateway 106 and the multiple sub-devices 104 connected to the gateway 106 through a local area network path, or can also interact with the gateway 106 and the multiple sub-devices 104 connected to the gateway 106 through a wide area network path. In addition, when the terminal device 102, the router 108, and the gateway 106 are not in the same local area network, the terminal device 102 can also interact with the gateway 106 and the multiple sub-devices 104 connected to the gateway 106 through a wide area network path. In addition, the terminal device 102 can also interact with the server 110 through a specified communication method, where the specified communication method includes: 2G (2-Generation wireless telephone technology, second-generation mobile phone communication technology specifications), 3G (3rd-Generation, third-generation mobile communication technology), 4G (the 4th generation mobile communication technology, fourth-generation mobile communication technology), 5G (5th-Generation Mobile Communication Technology, fifth-generation mobile communication technology) and wireless network communication technology WIFI, etc., which can be set specifically according to actual conditions.

[0052] Among them, the server 110 can also be considered as the cloud, cloud platform, platform end, service end, etc. This server 110 can be a single server, or a server cluster composed of multiple servers, or a cloud computing center composed of multiple servers, so as to better provide background services to the terminal device 102. For example, the background service may include sub-device control services, etc.

[0053] Furthermore, the automation of the smart home system 10 is a linkage application built between the gateway 106 or multiple sub-devices 104 connected to the gateway 106, including a trigger device and a controlled device (or an execution device), which are connected to each other through the gateway 106. When the trigger device meets the trigger condition, the gateway 106 controls the controlled device to perform the corresponding execution action. Among them, the trigger device can be various sensors, such as pressure sensors, temperature sensors, humidity sensors, door and window sensors or smoke sensors, etc.; the controlled device can be various switches, sockets, electric lights, infrared transmitters and camera devices, etc. It should be noted that in some cases, the trigger device and the controlled device can be the same device, which can be set according to actual conditions.

[0054] For example, the sub-devices 104 are respectively a smart doorbell and a smart door lock. Figure 2 As shown, the smart doorbell can be installed outdoors. In some embodiments, the smart doorbell may include a control module and a communication module connected to the control module. Furthermore, the smart door lock may include a front lock (outdoor lock) for installation outdoors and a rear lock (indoor lock) for installation indoors; the door lock may also include a door lock main control module and a door lock communication module with the door lock main control module. The door lock can establish a wireless communication connection with the communication module of the smart doorbell through the door lock communication module.

[0055] Optionally, the sub-device 104 may include a long power supply device. It should be understood that the long power supply device used in the door lock opening method of the present application may include not only the above-mentioned smart doorbell, but also other application forms, such as long-power supply gun cameras near the gate, garage shutters, long-power supply password input keyboards and other electronic devices, and is not limited to the forms mentioned in the above embodiments, as long as the above-mentioned long power supply device can realize the function of long power supply for the UWB module.

[0056] Before introducing the specific embodiments of the present application, the professional terms involved in the present application are explained first:

[0057] UWB (Ultra Wide Band) technology: Ultra Wide Band technology is a wireless carrier communication technology that does not use a sinusoidal carrier but uses nanosecond non-sinusoidal narrow pulses to transmit data, so it occupies a wide spectrum range. UWB technology can also detect human body movements that are difficult to detect (such as breathing, slight movement).

[0058] Passive Infrared Radiation (PIR): Any object with temperature is constantly radiating infrared rays to the outside world. The surface temperature of the human body is 36-27°C, and most of its radiation energy is concentrated in the wavelength range of 8-12um. The passive infrared alarm can be structurally divided into an infrared detector (infrared probe) and an alarm control part.

[0059] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0060] In an exemplary embodiment, Figure 3As shown, a door lock opening method is provided, and the method is applied to the above-mentioned long power supply device as an example for explanation. The long power supply device includes a UWB module, and the long power supply device and the UWB module are in a long power supply state. The method includes the following steps 302 to 304. Among them:

[0061] Step 302: Acquire the UWB signal collected by the UWB module.

[0062] The UWB module in the long power supply device may refer to a module with UWB function, which can realize the UWB function by collecting and outputting UWB signals. Furthermore, the long power supply device and the UWB module are in a long power supply state, which can be understood as a state in which the required power can be obtained stably and continuously.

[0063] Specifically, the long power supply device collects UWB signals through the built-in UWB module. Based on the collected UWB signals, it can achieve accurate positioning of outdoor objects, and then cooperate with the door lock to achieve contactless unlocking.

[0064] Exemplarily, the UWB signal collected by the UWB module can be sent by the UWB signaling device of the outdoor object, and the UWB signaling device can refer to a terminal device with a UWB signaling function (or a UWB signaling function). For example, the UWB signaling device may include a mobile phone, a watch, a pet smart collar equipped with a UWB transmitter, etc. Furthermore, the UWB signaling device can establish UWB communication with a long-powered device. It can be understood that the specific type of the above-mentioned UWB signaling device is not limited to the implementation method mentioned in the above-mentioned embodiment. As long as it can realize the UWB function, the present application does not specifically limit the specific type of the UWB signaling device.

[0065] In actual applications, the long-power supply device can wake up the UWB module to collect UWB signals. Optionally, the operating mode of the UWB module may include a sleep mode and a wake-up mode. Among them, the sleep mode can be a standby state in which the UWB module turns off most power-consuming functions and only maintains power supply; the wake-up mode can be the working state of the UWB module after turning on the UWB function. In the case where it is not necessary to accurately locate the terminal device of the outdoor object, the UWB module in the long-power supply state can be controlled to enter the sleep mode to reduce the power consumption of the long-power supply device, thereby reducing the operating cost of the device. In the case of needing to locate the terminal device with unlocking authority, the UWB module in the long-power supply state can be controlled to be activated from the sleep mode and enter the wake-up mode, so that it can collect and output UWB signals, thereby achieving accurate positioning of the terminal device of the outdoor object.

[0066] Regarding long power supply equipment, in some embodiments, the long power supply equipment may include smart doorbells, long power supply gun cameras near the gate, garage shutters, long power supply password input keyboards and other electronic devices. The specific types of the above-mentioned long power supply equipment are not limited to the implementation methods mentioned in the above-mentioned embodiments. As long as it is in a long power supply state with the UWB module, this application does not make specific limitations on the specific implementation form of the long power supply equipment.

[0067] It should be noted that the smart door lock and the long power supply device are respectively packaged as two independent devices; the long power supply device is powered by the mains, while the smart door lock is powered by a battery or other energy storage unit. For example, if the long power supply device is a smart doorbell with long power supply, the smart doorbell with long power supply and the smart door lock are respectively packaged in two independent shells, and a wireless communication connection is established between the two.

[0068] Step 304: If it is determined according to the UWB signal that an outdoor object is close to the door lock, an unlocking instruction is sent to the door lock; the unlocking instruction is used to instruct the door lock to perform an unlocking operation.

[0069] In one embodiment, the door lock (smart door lock) and the long power supply device are both installed on the outdoor side of the door. The long power supply device can obtain the relative position information between the outdoor object and the door lock (smart door lock) / long power supply device by parsing the UWB signal. Exemplarily, the relative distance and / or relative orientation of the terminal device of the outdoor object relative to the door lock / long power supply device can be parsed according to the UWB signal. It can be understood that by parsing the UWB signal, it is possible to accurately locate the outdoor object, thereby determining whether to send an unlocking instruction to the door lock based on the accurate positioning information.

[0070] Specifically, the long power supply device accurately locates the outdoor object according to the UWB signal, and when it is determined according to the UWB signal that the outdoor object is close to the door lock / long power supply device, it sends an unlocking instruction to the door lock to instruct the door lock to perform an unlocking operation.

[0071] Further, the unlocking instruction can be used to instruct the door lock to perform an unlocking operation when it is determined that an outdoor object is close to the door lock. Optionally, the unlocking instruction can be sent via a wireless communication connection such as Bluetooth communication.

[0072] Exemplarily, an outdoor object may refer to an object within a certain range of the area outside the smart door lock. In some possible implementations, the outdoor object may be a passerby passing by the area outside the smart door lock, a resident or a visiting guest who is about to unlock the door and enter the house, or an animal carrying a UWB signaling device (e.g., a cat or dog wearing a smart collar with UWB function).

[0073] It should be noted that the types of outdoor objects are not limited to the implementation methods mentioned in the above embodiments. As long as they are within a certain range of the area outside the smart door lock and hold a UWB signaling device, they can be regarded as outdoor objects. This application does not specifically limit the specific types of outdoor objects. It should be noted that the certain range of the area outside the smart door lock can be delineated according to the actual application needs of the door lock, and this application does not specifically limit the above range.

[0074] Optionally, the door lock can be a smart door lock that establishes a communication connection with a long power supply device. After receiving the unlocking instruction from the long power supply device, the door lock can perform a corresponding unlocking operation. Optionally, the unlocking instruction can also be used to instruct the door lock to perform operations such as playing a door opening prompt sound and lighting a door lock prompt light to remind outdoor objects that the door lock has been opened. It can be understood that in addition to being used to instruct the door lock to perform an unlocking operation, the unlocking instruction can also be used to instruct the door lock to perform other types of actions. The specific action type can be determined according to the specific hardware configuration of the door lock and the requirements of the application scenario, and this application will not go into details here.

[0075] It is understandable that the realization of UWB functions requires high energy consumption for precise positioning and distance measurement. In traditional technologies, smart door locks are powered by energy storage devices such as batteries. This method is difficult to maintain a long battery life, and this problem is often alleviated by actively reducing the positioning performance of the UWB module or increasing the cost to purchase a larger capacity battery. However, this application enables the long power supply device and the UWB module to be in a long power supply state, and then enables the long power supply device to communicate with the smart door lock. This can not only solve the problem that the performance of the UWB module is limited by the battery life, but also enable the UWB module to maintain long-term operation in a high-performance state, and can provide accurate positioning services, thereby realizing the convenient unlocking of the smart door lock.

[0076] In one embodiment, determining that an outdoor object is close to a door lock according to a UWB signal includes:

[0077] If it is determined based on the UWB signal that the outdoor object meets the unlocking condition, then it is determined that the outdoor object is close to the door lock; wherein the unlocking condition represents the position condition that the relative position of the outdoor object relative to the door lock needs to meet;

[0078] The relative position includes the relative distance of the terminal device of the outdoor object relative to the door lock, and the position condition includes the distance condition; and / or, the relative position includes the relative orientation of the terminal device of the outdoor object relative to the door lock, and the position condition includes the orientation condition.

[0079] The unlocking condition refers to the position condition that the relative position of the terminal device of the outdoor object relative to the smart door lock needs to meet when the outdoor object needs to control the smart door lock to perform related actions. In some embodiments, the position condition may include a distance condition and / or an orientation condition.

[0080] Exemplarily, the distance condition may be that the relative distance between the terminal device of the outdoor object and the door lock meets a certain distance requirement. For example, when the relative distance between the terminal device of the outdoor object and the door lock is less than a specified distance threshold, it is determined that the outdoor object meets the unlocking condition.

[0081] Furthermore, the orientation condition may be that the relative orientation of the terminal device of the outdoor object relative to the door lock meets a certain orientation requirement. For example, when the relative orientation of the terminal device of the outdoor object relative to the door lock is within a specified orientation angle range, it is determined that the outdoor object meets the unlocking condition.

[0082] Specifically, based on the collected UWB signal, when the relative position of the terminal device of the outdoor object meets the preset position condition, the long power supply device can determine that the outdoor object meets the unlocking condition, and thus can send an unlocking instruction to the door lock to instruct the door lock to perform the unlocking operation. In this way, the accuracy of controlling the intelligent door lock to perform the unlocking operation is improved.

[0083] In one embodiment, the distance condition may include a preset unlocking distance; before determining that the outdoor object meets the unlocking condition based on the UWB signal, the process includes:

[0084] Receiving configuration information from a terminal device; the configuration information is generated by the terminal device based on the configuration instructions obtained from the unlocking distance configuration interface;

[0085] The preset unlocking distance is obtained based on the configuration information.

[0086] Among them, when the distance between the terminal device of the outdoor object and the door lock meets the preset unlocking distance, it can be determined that the terminal device of the outdoor object meets the distance condition. It can be understood that the preset unlocking distance can be set according to the detection performance of the UWB module and the specific application scenario requirements, and the present application does not specifically limit the specific numerical range of the preset unlocking distance.

[0087] Specifically, the user can set the preset unlocking distance in the unlocking distance configuration interface on the terminal device. After the preset unlocking distance is set, the terminal device for which the user sets the preset unlocking distance will send a configuration instruction to the long power supply device. The long power supply device sets the distance condition based on the configuration information of the preset unlocking distance contained in the configuration instruction, so that when the distance of the terminal device of the outdoor object relative to the door lock meets the preset unlocking distance, it is determined that the outdoor object meets the distance condition. In the above manner, the present application enables the user to flexibly configure the unlocking distance through the unlocking distance configuration interface on the terminal device, effectively improving the flexibility and personalization of the unlocking function.

[0088] It should be noted that the terminal device for setting the preset unlocking distance and the terminal device for the outdoor object can be the same terminal device or different terminal devices. Exemplarily, the terminal device for setting the preset unlocking distance can be a terminal device with administrator privileges, such as a mobile phone, tablet computer, smart watch, etc. of the owner of the house with an unlocking distance configuration interface; the terminal device for the outdoor object can be a terminal device with UWB function, such as a mobile phone, tablet computer and smart watch of a visiting guest, or a terminal device such as a smart collar with UWB signaling function worn by a pet.

[0089] It can be understood that the terminal device of the above-mentioned outdoor object does not have to have the function of setting a preset unlocking distance, and the terminal device for setting a preset unlocking distance is not limited to the implementation method mentioned in the above-mentioned embodiment. As long as it can realize the function of configuring a preset unlocking distance, the present application does not specifically limit the specific implementation form of the terminal device for setting a preset unlocking distance.

[0090] In one embodiment, before acquiring the UWB signal collected by the UWB module, the method includes:

[0091] When the outdoor object is determined to be the unlocking object, the UWB module is started;

[0092] After sending the unlock command to the door lock, including:

[0093] Turn off the UWB module.

[0094] The unlocking object may be an outdoor object with unlocking authority of the smart door lock. Optionally, whether the outdoor object has unlocking authority may be confirmed by pre-stored key information to determine whether the outdoor object is an unlocking object. Exemplarily, the pre-stored key information may include a UWB key.

[0095] Specifically, before accurately locating an outdoor object through the UWB module, it is necessary to first determine whether the outdoor object is an unlocking object with unlocking authority. If the outdoor object is an unlocking object, the outdoor object is accurately located through the UWB module. When the outdoor object is determined to be close to the door lock based on the collected UWB signal, an unlocking instruction is sent to the door lock to instruct the smart door lock to perform the unlocking operation. In this way, the security of automatic unlocking is improved.

[0096] In addition, when the long power supply device sends an unlocking command to the smart door lock, the UWB module is turned off to stop the UWB module from accurately locating outdoor objects, thereby reducing the energy consumption of the long power supply device.

[0097] In one embodiment, if Figure 4 As shown, the long power supply device also includes an identification module; determining that the outdoor object is an unlocking object includes the following steps S402 to S404. Among them:

[0098] Step S402: obtaining an identification signal of a terminal device of an outdoor object by an identification module.

[0099] The identification module can be used to identify whether the terminal device of the outdoor object has the unlocking authority. For example, if the identification module identifies that the terminal device of the outdoor object has the unlocking authority, it outputs an identification signal of having the unlocking authority; if the identification module identifies that the terminal device of the outdoor object does not have the unlocking authority, it outputs an identification signal of not having the unlocking authority.

[0100] Exemplarily, the recognition module can set a preset period for scanning and recognition according to the environmental conditions of the area in front of the smart door lock. Optionally, when the environment of the area in front of the smart door lock is relatively complex, for example, when there are many obstacles (such as large potted plants, shoe cabinets, etc.) piled up in the area in front of the door, the preset period for scanning by the recognition module can be set to be smaller, thereby improving the recognition efficiency of the recognition module; when the environment of the area in front of the smart door lock is relatively open and flat, the preset period for scanning by the recognition module can be set to be larger, thereby reducing the power consumption of the long power supply equipment and saving electricity. Optionally, the value range of the preset period for scanning by the recognition module can include scanning once every 100~500ms.

[0101] In some possible implementations, if it is identified that the terminal device of the outdoor object has logged into an application client account with unlocking authority, the identification module can confirm that the terminal device of the outdoor object is a registered device, and correspondingly output an identification signal indicating that the terminal device has unlocking authority. In some embodiments, the registered device can be a terminal device holding pre-stored key information as described in the above embodiments, or it can be a terminal device with shared unlocking authority. Optionally, the identification module can identify whether the terminal device of the outdoor object has logged into an application client account with unlocking authority through Bluetooth.

[0102] Specifically, the identification module outputs a corresponding identification signal according to the identification result of the outdoor object, so as to determine whether the outdoor object has the unlocking authority according to the identification signal. It can be understood that the terminal device of the outdoor object is authenticated by the identification module, which effectively improves the security of the unlocking function.

[0103] Step S404: If it is determined according to the identification signal that the terminal device of the outdoor object has the unlocking authority, the outdoor object is confirmed as an unlocking object.

[0104] Specifically, when the terminal device of the outdoor object is confirmed to have unlocking authority according to the identification signal, the outdoor object identified above is determined to be the unlocking object, and the UWB module is started accordingly to accurately locate the outdoor object. The present application uses the identification module to identify the unlocking authority of the outdoor object, effectively improving the security and reliability of the unlocking function.

[0105] In one embodiment, the identification module includes a Bluetooth module; the identification signal includes a Bluetooth signal between the Bluetooth module and a terminal device within a Bluetooth scanning range;

[0106] Before obtaining the identification signal of the identification module for the terminal device of the outdoor object, it includes:

[0107] The Bluetooth module performs Bluetooth signal scanning at a preset period, and when a Bluetooth signal of a terminal device of an outdoor object is scanned, a Bluetooth connection is established with the terminal device of the outdoor object through the Bluetooth module.

[0108] Among them, the Bluetooth module can be used to scan Bluetooth signals at a preset period, and establish a Bluetooth connection with the terminal device when scanning the Bluetooth signal of the terminal device of the outdoor object, and collect the Bluetooth signal emitted by the terminal device of the outdoor object as an identification signal output.

[0109] Optionally, in the case where the UWB module has very high power consumption, it can be made to enter an extremely low power sleep mode when there is no need to measure the distance and position the terminal device, and the Bluetooth module with relatively low power consumption can be scanned at a preset period.

[0110] Specifically, the Bluetooth module can scan the designated area at a preset period. If a terminal device of an outdoor object enters the scanning area of ​​the Bluetooth module, the Bluetooth module establishes a Bluetooth connection with the terminal device of the outdoor object and outputs the Bluetooth signal sent by the terminal device as an identification signal to determine whether the outdoor object has the unlocking authority based on the Bluetooth signal. It can be understood that the use of the Bluetooth module has the advantages of low power consumption and low production cost.

[0111] In one embodiment, before obtaining the UWB signal collected by the UWB module, the following steps S502 to S504 are included. Among them:

[0112] Step S502, receiving a pairing instruction sent by the terminal device; the pairing instruction is obtained by the terminal device based on the device configuration interface.

[0113] Among them, the pairing instruction can be used to instruct the long power supply device to establish a wireless communication connection with the smart door lock.

[0114] Specifically, after completing the pairing of the long power supply device and the smart door lock in the device configuration interface of the terminal device, the terminal device will send a corresponding pairing instruction to the designated long power supply device; after receiving the pairing instruction, the long power supply device will establish a wireless communication connection with the smart door lock.

[0115] It should be noted that the terminal device for pairing the device in the device configuration interface and the terminal device of the outdoor object can be the same terminal device or different terminal devices. Exemplarily, the terminal device that sends the pairing instruction can be a terminal device with administrator privileges, such as the mobile phone, tablet computer, smart watch, etc. of the house owner that has a device configuration interface.

[0116] It can be understood that the terminal device for device pairing is not limited to the implementation methods mentioned in the above embodiments. As long as it can perform device pairing between a specified long power supply device and a specified smart door lock, this application does not specifically limit the specific implementation form of the terminal device for device pairing.

[0117] Step S504: establishing a wireless communication connection with the door lock based on the pairing instruction.

[0118] Among them, the wireless communication connection between the long power supply device and the smart door lock can be used to transmit control signals such as unlocking instructions. Optionally, the wireless communication connection between the long power supply device and the smart door lock can be a P2P (Peer-to-Peer) communication connection, through which the long power supply device and the smart door lock can achieve point-to-point communication, thereby improving system performance and stability.

[0119] Specifically, after receiving the pairing command sent by the terminal device, the long power supply device can establish a wireless communication connection with the smart door lock. It can be understood that the UWB module in the traditional technology requires the built-in power supply of the smart door lock for line power supply, which greatly limits the installation position of the UWB module and greatly affects the battery life of the smart door lock. The long power supply device with a built-in UWB module in this application establishes a wireless communication connection with the smart door lock, which gets rid of the restrictions of the smart door lock on the installation position of the UWB module, improves the flexibility of the UWB module, and does not affect the battery life of the smart door lock.

[0120] Furthermore, sending an unlock instruction to the door lock may include:

[0121] Send unlocking instructions to the door lock via wireless communication connection.

[0122] Specifically, based on the wireless communication connection between the long power supply device and the smart door lock, the long power supply device can send an unlocking instruction to the smart door lock when it is determined that an outdoor object is approaching the door lock, so as to instruct the smart door lock to perform an unlocking operation.

[0123] In a possible implementation, sending an unlock instruction to a door lock further includes the following steps:

[0124] The unlocking instruction is encrypted to obtain an encrypted unlocking instruction, and the encrypted unlocking instruction is transmitted to the door lock via a wireless communication connection; wherein the encrypted unlocking instruction can be used to instruct the door lock to decrypt to obtain a decryption instruction, so as to perform an unlocking operation based on the decryption instruction.

[0125] Exemplarily, the long power supply device may encrypt the unlocking instruction using a preset encryption algorithm to obtain an encrypted unlocking instruction. Optionally, the preset encryption algorithm may be an Advanced Encryption Standard (AES) algorithm.

[0126] Specifically, the wireless communication connection between the long power supply device and the smart door lock can be encrypted by the AES algorithm. By encrypting the wireless communication connection between the long power supply device and the smart door lock, the security and reliability of the unlocking function can be effectively improved.

[0127] In one embodiment, obtaining a UWB signal collected by a UWB module includes:

[0128] Decrypting the UWB signal using pre-stored key information to obtain a decrypted UWB signal;

[0129] The pre-stored key information includes key information corresponding to the registered terminal device; wherein the registered terminal device indicates that the terminal device has the unlocking authority.

[0130] The pre-stored key information can be used to encrypt and decrypt UWB communication between the UWB module and the terminal device of the outdoor object. Optionally, the pre-stored key information can include a UWB key, and the terminal device holding the corresponding UWB key can have the unlocking authority to open the smart door lock.

[0131] In some possible implementations, the terminal device can register the device on the long-power supply device in a preset registration method to enter the pre-stored key information into the long-power supply device. Exemplarily, the preset registration method can be to register the device through NFC (NearField Communication), so that the long-power supply device registers that the terminal device has the unlocking authority.

[0132] In some embodiments, the pre-stored key information can also be shared with other terminal devices through the application client of the terminal device (such as a mobile phone APP) to share the unlocking authority with other terminal devices. Optionally, the terminal device that can share the unlocking authority needs to have the management authority of the long power supply device and the smart door lock.

[0133] Specifically, when the long power supply device collects UWB signals through the UWB module, the collected UWB signals are decrypted through the pre-stored key information, and the terminal device of the outdoor object is accurately located based on the decrypted UWB signal. The communication between the UWB module and the terminal device of the outdoor object is encrypted and decrypted through the pre-stored key information, which effectively improves the reliability and security of UWB positioning.

[0134] In one embodiment, if Figure 5 As shown, the long power supply device further includes an image acquisition module; the method further includes the following steps S602 to S604. Among them:

[0135] Step S602: If it is determined according to the UWB signal that an outdoor object is close to the door lock, an image acquisition module is started to obtain image information.

[0136] The image acquisition module may be used to acquire and output image information. Exemplarily, the image information may be image information of a specified image acquisition area. In some possible implementations, the image acquisition area may be a certain area outside the smart door lock, and the specific situation of the outdoor object may be known based on the image information within the area. Optionally, the image acquisition module may include a camera.

[0137] Specifically, when it is determined that an outdoor object is close to the door lock according to the UWB signal, the image acquisition module of the long power supply device is started to obtain image information of a certain area outside the door. Optionally, when the long power supply device does not perform UWB positioning on the outdoor object, the image acquisition module can be turned off by default to save energy.

[0138] Step S604: in response to receiving a stream pull request from a terminal device, sending image information to the terminal device.

[0139] The stream pull request may be a request for pulling image information issued by a terminal device. Optionally, the terminal device that issues the stream pull request needs to have management authority for a long power supply device and a smart door lock.

[0140] Specifically, when the long power supply device receives a streaming request from a terminal device, it can start the image acquisition module and instruct the image acquisition module to obtain image information of the image acquisition area, and send the acquired image information to the terminal device that issued the streaming request. It can be understood that the image acquisition module allows the terminal device to easily obtain image information of the outdoor designated area, thereby improving the security of the unlocking function.

[0141] In an exemplary embodiment, Figure 6 As shown, the present application also provides a door lock opening method, which is applied to Figure 2 Taking the door lock (smart door lock) in the example as an example, the door lock is connected to a long power supply device, the long power supply device includes a UWB module, and the long power supply device and the UWB module are in a long power supply state. The method includes the following steps S702 to S704. Among them:

[0142] Step S702, receiving an unlocking instruction from the long power supply device; the unlocking instruction is sent by the long power supply device when it determines that an outdoor object is close to the door lock based on the UWB signal collected by the UWB module.

[0143] Specifically, the smart door lock can receive an unlocking instruction sent by the long power supply device when it determines that an outdoor object is approaching the door lock based on the UWB signal collected by the UWB module.

[0144] Step S704: Execute the unlocking operation according to the unlocking instruction.

[0145] Specifically, the smart door lock can perform corresponding unlocking operations according to the received unlocking instructions, so that outdoor objects can enter the room.

[0146] In some possible implementations, receiving an unlocking instruction from a long power supply device includes the following steps:

[0147] The encrypted unlocking instruction is decrypted to obtain a decrypted unlocking instruction; the decrypted unlocking instruction can be used to instruct the door lock to perform an unlocking operation.

[0148] Optionally, the encrypted unlocking instruction may be encrypted using an AES algorithm.

[0149] Specifically, when the door lock receives the encrypted unlocking instruction from the long power supply device, the encrypted unlocking instruction is decrypted to perform the unlocking operation according to the decrypted unlocking instruction.

[0150] It can be understood that the implementation solution to the problem provided by the above-mentioned door lock opening method implemented from the perspective of the door lock is similar to the implementation solution recorded in the above-mentioned door lock opening method implemented from the perspective of the long power supply device. Therefore, the specific limitations in one or more embodiments of the door lock opening method implemented from the perspective of the door lock provided below can be referred to the above limitations on the door lock opening method implemented from the perspective of the long power supply device, and will not be repeated here.

[0151] In one embodiment, the method further includes the following steps S802 to S804.

[0152] Step S802, receiving a pairing instruction sent by the terminal device; the pairing instruction is obtained by the terminal device based on the device configuration interface.

[0153] Specifically, the smart door lock can receive a pairing instruction sent by the terminal device based on the device configuration interface, and the pairing instruction can be used to establish a wireless communication connection between the long power supply device and the smart door lock.

[0154] Step S804: establishing a wireless communication connection with the long power supply device based on the pairing instruction.

[0155] Optionally, the wireless communication connection between the long power supply device and the smart door lock can be a P2P (Peer-to-Peer) communication connection. Through the P2P communication connection, point-to-point communication between the long power supply device and the smart door lock can be achieved, thereby improving system performance and stability.

[0156] Specifically, the smart door lock can establish a wireless communication connection with a designated long power supply device based on a pairing instruction, thereby realizing device pairing between the smart door lock and the long power supply device.

[0202] For example, the long power supply device may be Fig.10 A smart doorbell installed outside a door is shown. Optionally, on the one hand, the smart doorbell can trigger the doorbell master control through the PIR module or the ultrasonic positioning module to control the smart door unlocking through the communication chip; on the other hand, when the smart doorbell detects that the unlocking object enters a certain distance in front of the door through the UWB module, the doorbell master control will also send a control signal to the smart door connected to it to instruct the smart door to unlock automatically.

When the long-power supply password input keyboard detects through the UWB module that the unlocking object is within a certain distance of the password lock, the long-power supply password input keyboard will send an unlocking command to the password lock connected to it for automatic unlocking, thus providing another convenient unlocking method.

[0208] It can be understood that the type of the above-mentioned long power supply device is not limited to the implementation method mentioned in the above embodiment. As long as it can realize long power supply to the UWB module, this application will not go into details here.

[0209] In one embodiment, the present application provides a door lock opening system, the system includes a smart door lock and a long power supply device; wherein the smart door lock is in a battery-powered state, the long power supply device includes a control module and a UWB module, a power module and a communication module respectively connected to the control module; the power module includes a mains power interface for connecting to the mains power; the UWB module is coupled to the power module, and the power module and the UWB module are in a long power supply state; the control module is used to obtain the UWB signal collected by the UWB module; and if it is determined according to the UWB signal that an outdoor object is close to the door lock, an unlocking instruction is sent to the door lock through the communication module; the unlocking instruction is used to instruct the door lock to perform an unlocking operation.

[0210] Specifically, the door lock opening system may include a smart door lock (such as a separate door lock device) and a long-power supply device (such as a doorbell device). Taking the door lock device and the doorbell device, and the UWB module using the UWB chip as an example, the doorbell device can be powered by the mains, and the door lock device is powered by a battery. The UWB chip will be built into the doorbell device that can be powered by the mains, and then the UWB high frequency can be used to scan the user's location; when the user is found near the doorbell and the door lock by sensing the UWB signal, the doorbell device can communicate with the door lock device in an encrypted manner and send an unlocking command to the door lock device to unlock the door for the user. Through the embodiments of the present application, the door lock device (smart door lock) can provide users with a more stable and fast automatic unlocking experience, realize non-sensing unlocking, and at the same time ensure that it does not affect the endurance of the door lock, thereby improving the user's experience and reducing endurance anxiety.

[0211] In order to further illustrate the present application, a specific example is described below. Fig. 9 The long-power supply device 40 shown is an example of a smart doorbell capable of long-power supply, and the present application provides an exemplary specific implementation. Fig.11 , the specific implementation is as follows:

[0212] ①User and equipment preparation stage:

[0213] First, users can use terminal devices (such as mobile phones, tablet computers, etc.) to open the application client (i.e. Fig.11 The smart doorbell (i.e. Fig.11 Device side shown) and door lock device (i.e. Fig.11 The smart door lock shown in the figure) is used, and the smart door lock and the smart doorbell are paired and P2P encrypted on the device configuration interface of the application client, thereby establishing a local AES encrypted communication connection for wireless communication between the smart door lock and the smart doorbell.

[0214] Then, the user can register the UWB signaling device (such as a mobile phone / watch) on the smart doorbell through the terminal device, thereby registering the corresponding UWB key on the smart doorbell; for example, the registration method can be similar to the NFC registration method, so that the device side knows that the terminal device has the unlocking authority. Optionally, the application client account can also be associated and bound with the smart door lock and the smart doorbell, so that the account can obtain the management authority of the smart door lock and the smart doorbell.

[0215] Next, the user can set the unlocking distance in the unlocking distance configuration interface of the application client, and can also share the UWB unlocking permission of the above smart door lock with other users in the unlocking permission management interface. After the relevant parameters of the above configuration are set, they will be sent to the smart doorbell and door lock through the terminal device or the cloud, so that the parameter changes are synchronized on each end.

[0216] ②Equipment activation phase:

[0217] Since the power consumption of the UWB module is very high, when the smart doorbell does not detect any registered device, it is put into sleep mode, and the smart doorbell is kept powered for a long time through the AC power interface of the power module.

[0218] The smart doorbell uses the Bluetooth module to scan the area near the door at a cycle of every 100-500ms. If the Bluetooth device does not find any terminal device of an outdoor object entering the scanning area, it will continue to scan. When the smart doorbell detects that an outdoor object carrying a terminal device (i.e., a user device) enters the scanning range, it establishes a Bluetooth communication connection with the user device through the Bluetooth module. Based on the Bluetooth communication connection, if the smart doorbell recognizes through the Bluetooth signal that the user device has logged in to a client application account with unlocking authority, it determines that the terminal device carried by the outdoor object is a registered device, wakes up the built-in UWB module of the smart doorbell, and turns on the UWB ranging function of the UWB module to accurately locate the outdoor object.

[0219] The smart doorbell communicates with the user device through the UWB module, and continuously uses UWB signals to determine whether the registered device (such as a mobile phone) has reached the preset unlocking distance and outdoor position. During the UWB communication process, after receiving the UWB signal sent by the user device, the smart doorbell first decrypts the received UWB signal using the pre-registered UWB key, and determines whether the user device has reached the preset unlocking distance and outdoor position based on the decrypted UWB signal, and maintains continuous and accurate positioning of the user device.

[0220] If the UWB module's ranging results show that the user device has reached the preset unlocking distance and outdoor position, and is still approaching the device, the smart doorbell sends an encrypted unlocking command to the smart door lock through wireless communication (such as Thread, Zigbee, BLE and other communication modules), and simultaneously ends the UWB ranging and turns off the UWB module (enters sleep mode).

[0221] After receiving the encrypted unlocking command (i.e., the encrypted command), the smart door lock first decrypts the encrypted command to verify the security of the command. If the unlocking command is successfully verified, the smart door lock will perform the unlocking operation, allowing the user to unlock and enter the house; if the unlocking command fails to be verified, an error will be fed back through the device.
