Description

Technical Field

[0001] This invention relates to the field of smart lock technology, and in particular to a method, system, smart lock, and computer-readable storage medium for express delivery based on a smart lock. Background Technology

[0002] In today's society, every household receives numerous packages. When no one is home to sign for them, they are often left at the door. This raises questions about the exact number of packages received, whether any were lost while left at the door, and the hassle of tracking purchases from different online shopping platforms. Furthermore, when valuable items require a signature code, it's difficult to contact the recipient, which also hinders the courier's ability to handle the situation. Similarly, when returning goods, if the recipient leaves the package at the door but the courier needs the pickup code, they are unable to contact the recipient and thus cannot complete the process.

[0003] Therefore, current delivery personnel contact users by phone to communicate about package delivery, delivery codes, and pickup codes. When they cannot reach the user, they cannot process the package. In other words, there are significant loopholes and inconveniences in the current package delivery and return process. Existing technology does not utilize smart door locks for corresponding package processing.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The main objective of this invention is to provide a method, system, smart lock, and computer-readable storage medium for express delivery processing based on smart locks, aiming to solve the problem that existing technologies cannot effectively manage the signing and return of express deliveries using smart locks, thus failing to provide convenience for users in express delivery management.

[0018] The delivery tracking number can be entered by the courier typing on the keyboard, scanning the barcode on the waybill through the courier's camera, or by the courier's voice input.

[0019] The specific steps for entering the returned express tracking number are as follows:

[0020] The returned package tracking number can be entered by the courier typing on the keyboard, scanning the barcode on the waybill through a peephole, or by the courier using voice input.

[0021] Optionally, the express delivery processing method based on smart door locks, wherein if the courier's requirement is for the user to sign for the express delivery or to obtain a signature code, the courier enters the express delivery tracking number to be signed for, matches the signature code according to the express delivery tracking number to be signed for, and broadcasts the signature code, specifically includes:

[0022] According to the courier's confirmation operation, if the courier needs the user to sign for the package or needs a signature code, the courier will enter the package number to be signed for through keyboard input, scanning the barcode on the package slip through the courier's camera, or voice input.

[0023] The system matches the pending delivery tracking number with the stored delivery code. If a matching delivery code is found, the code is broadcast so that the courier can confirm and complete the delivery signing.

[0024] Optionally, the express delivery processing method based on smart door locks, wherein if the courier's requirement is a pickup code, the returned express tracking number is entered, a pickup code is matched according to the returned express tracking number, and the pickup code is broadcast, specifically includes:

[0025] If the courier confirms that the courier needs a pickup code, the returned package tracking number can be entered by the courier by typing it on the keyboard, scanning the barcode on the waybill through the courier's camera, or by the courier's voice input.

[0026] The returned package tracking number is matched with the stored pickup code. If a matching pickup code is found, the pickup code is broadcast so that the courier can confirm and complete the return of the package.

[0027] Optionally, the express delivery processing method based on smart door locks further includes:

[0028] Once the courier has completed delivery or pickup, the courier information will be updated and displayed on the APP or mini-program page so that users can know the delivery or pickup information.

[0029] Furthermore, to achieve the above objectives, the present invention also provides a smart door lock-based express delivery processing system, wherein the smart door lock-based express delivery processing system includes:

[0030] The visitor recognition module is used to wake up the peephole for visitor recognition when the smart door lock's delivery assistant function is activated, based on doorbell triggering or sensor detection.

[0031] The voice prompt module is used to prompt the courier whether the user needs to sign for the package, whether a signature code is needed, and whether a pickup code is needed if the courier is detected.

[0032] The demand confirmation module is used to detect the number keys entered on the keypad of the smart door lock or to recognize the courier's voice response and determine whether the courier's demand is for the user to sign for the package, for a signature code, or for a pickup code.

[0033] The signature processing module is used to input the tracking number to be signed for or to match the signature code with the tracking number if the courier needs the user to sign for the package or to provide a signature code. The module then announces the signature code.

[0034] The return processing module is used to input the returned package tracking number if the courier requires a pickup code, match the pickup code according to the returned package tracking number, and announce the pickup code.

[0035] In addition, to achieve the above objectives, the present invention also provides a smart lock, wherein the smart lock includes: a memory, a processor, and a smart lock-based express delivery processing program stored in the memory and executable on the processor, wherein when the smart lock-based express delivery processing program is executed by the processor, it implements the steps of the smart lock-based express delivery processing method as described above.

[0036] Furthermore, to achieve the above objectives, the present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a smart lock-based express delivery processing program, which, when executed by a processor, implements the steps of the smart lock-based express delivery processing method described above.

[0037] In this invention, when the smart lock's delivery assistant function is activated, the doorbell trigger or sensor detection activates the peephole for visitor identification. If a delivery person is identified, a voice prompt is sent asking if the user needs to sign for the package, require a signature code, or need a pickup code. After detecting the numeric keypad input on the smart lock or recognizing the delivery person's voice response, the system determines the delivery person's request: a signature, a signature code, or a pickup code. If the request is for a signature or a signature code, the system enters the tracking number, matches it with a signature code, and announces the signature code. If the request is for a pickup code, the system enters the returned tracking number, matches it with a pickup code, and announces the pickup code. This invention effectively handles package signing and returns via smart locks, facilitating package management and greatly improving security, convenience, and efficiency.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] The preferred embodiment of the express delivery processing method based on smart door locks described in this invention, such as... Figure 1 and Figure 2 As shown, the express delivery processing method based on smart door locks includes the following steps:

[0047] Step S10: When the smart door lock’s delivery assistant function is detected to be activated, the doorbell is triggered or the sensor is detected to wake up the peephole for visitor identification.

[0048] Specifically, the smart lock receives an operation command from the user via APP, mini-program, Internet, or Bluetooth to activate the courier assistant function (the courier assistant function can be understood as a program for managing couriers, installed on the smart lock for courier management). The smart lock then activates the courier assistant function according to the operation command. When the courier assistant function is activated, the lock continuously checks whether a doorbell trigger operation (i.e., a courier presses the doorbell while the courier assistant function is activated) or sensor detection (such as radar, PIR, etc., to detect whether there is someone outside the door) occurs. If a doorbell trigger operation or sensor detection occurs, the courier assistant function is triggered to wake up the peephole for visitor identification.

[0049] When the delivery assistant function is turned off, the smart lock function returns to normal. The doorbell function is normal but cannot trigger the delivery assistant function, or the sensors (radar, PIR, etc.) cannot wake the peephole to identify the delivery person. That is... Figure 3 As shown, first determine whether the Express Assistant function is enabled. If the Express Assistant function is enabled, the smart door lock will enable the functions of signing for orders and responding with the signature code or pickup code; if the Express Assistant function is disabled (or not enabled), the smart door lock will disable the functions of signing for orders and responding with the signature code or pickup code.

[0050] Step S20: If the courier is identified, the courier will be prompted by voice whether the user needs to sign for the package, whether a signature code is required, and whether a pickup code is required.

[0051] Specifically, when the courier assistant function is triggered to wake up the doorbell and identify visitors, if the identification result determines that the person outside the door is a courier (e.g., based on the courier's attire), the smart door lock can provide voice prompts (i.e., voice inquiries) to the courier to ask whether the user needs to sign for the package (for ordinary packages), whether a signature code is needed (for valuables), and whether a pickup code is needed (for returned packages).

[0052] Step S30: After detecting the number keys input on the keypad of the smart door lock or recognizing the courier's voice response, determine whether the courier's request is for the user to sign for the package, for a signature code, or for a pickup code.

[0053] Specifically, after the smart lock prompts the courier via voice whether the user needs to sign for the package, whether a signature code is required, or whether a pickup code is required, the courier can input number keys on the smart lock's keypad according to the voice prompts. For example, the number 1 indicates that the user needs to sign for the package, the number 2 indicates that a signature code is required, and the number 3 indicates that a pickup code is required. Alternatively, the courier can directly select whether the user needs to sign for the package, whether a signature code is required, or whether a pickup code is required by voice reply. The smart lock determines the courier's needs as requiring the user to sign for the package, whether a signature code is required, or whether a pickup code is required based on the courier's number input or voice reply.

[0054] Step S40: If the courier's requirement is for the user to sign for the package or to obtain a signature code, enter the package tracking number to be signed for, match the signature code according to the package tracking number to be signed for, and announce the signature code.

[0055] Specifically, based on the courier's confirmation, if the courier needs the user to sign for the package or requires a signature code (both indicating the user needs to sign for the current package), the courier will input the tracking number to be signed for via keyboard input, scanning the barcode on the waybill using the smart lock, or voice input (the method of inputting the tracking number can vary). The system will also pre-assign all unprocessed package signature codes based on the user's settings in the app or mini-program, or by linking the smart lock to the courier platform. The pickup code is automatically entered into the smart lock for storage (this can be set by the user or automatically entered by linking the user's mobile phone number to the courier platform; input parameters include order number, signature code or pickup code, time, etc.). Entering the signature codes and pickup codes of all unprocessed packages is to facilitate matching with the tracking numbers entered by the courier later. The tracking numbers to be signed for are matched with the stored signature codes. If a matching signature code is found, the signature code is announced so that the courier can confirm and complete the package signing.

[0056] Step S50: If the courier requires a pickup code, enter the returned courier tracking number, match the pickup code according to the returned courier tracking number, and announce the pickup code.

[0057] Specifically, if the courier confirms that their request is for a pickup code (indicating a return or exchange), the courier enters the returned tracking number via keyboard input, scanning the barcode on the waybill using a peephole, or voice input. The returned tracking number is then matched with the stored pickup codes. If a matching code is found, it is announced so the courier can confirm and complete the return process.

[0058] For example, in a return scenario, the user leaves the package at their doorstep, the courier rings the doorbell to trigger the process, and the smart lock will give a voice prompt asking if the package needs to be picked up. Then, the courier enters the tracking number via voice prompt and the lock will announce the pickup code. After verifying the pickup code, the courier successfully retrieves the package and leaves. If the pickup code is not set in the app, the lock cannot announce the code. For example, if the user forgets to set the pickup code in the app, the smart lock cannot obtain the pickup code and therefore cannot announce the code.

[0059] Furthermore, such as Figure 2 As shown, after broadcasting the delivery code or pickup code, the system can prompt the courier whether they need to listen to the delivery code or pickup code again. If they need to listen to the delivery code or pickup code again, the system can broadcast the delivery code or pickup code again according to the courier's request.

[0060] Furthermore, such as Figure 4As shown, the smart door lock completes the order signing and uploads the signed order to the APP, enabling users to view the signed order on the APP. That is, when the courier completes the delivery or pickup, the courier information is updated and displayed on the APP or mini program page so that users can understand the delivery or pickup information (i.e., the signed order display page function, the APP page can display the order number, signing time and other information signed today).

[0061] like Figure 5 As shown, the APP sets the delivery code or pickup code: The APP must first set the delivery code and pickup code, and the order number must correspond to the delivery code or pickup code; The smart door lock obtains the delivery code or pickup code: The smart door lock submits the order number, and the platform verifies whether the order number and the delivery code or pickup code correspond. If they correspond, the smart door lock will broadcast the delivery code or pickup code.

[0062] This invention effectively manages package signing and returns via a smart door lock. When the smart door lock activates the package assistant function, it triggers the doorbell camera for visitor identification based on the courier's action or sensor detection. Once the courier is identified, the system determines their request based on their confirmation: a package signature, a signature code, or a pickup code. If the request is for a signature or a signature code, the tracking number is entered, a signature code is matched, and the signature code is announced. If the request is for a pickup code, the tracking number is entered, a pickup code is matched, and the pickup code is announced. This facilitates package management, reduces or eliminates user intervention, and greatly improves security, convenience, and efficiency.

[0063] Furthermore, such as Figure 6 As shown, based on the above-described express delivery processing method based on smart locks, the present invention also provides an express delivery processing system based on smart locks, wherein the express delivery processing system based on smart locks includes:

[0064] The visitor recognition module 51 is used to wake up the peephole for visitor recognition when the smart door lock’s delivery assistant function is detected to be activated, based on the doorbell trigger operation or sensor detection.

[0065] The voice prompt module 52 is used to prompt the courier whether the user needs to sign for the package, whether a signature code is needed, and whether a pickup code is needed if the courier is detected.

[0066] The demand confirmation module 53 is used to detect the number keys input on the keypad of the smart door lock or to recognize the courier's voice reply and determine whether the courier's demand is for the user to sign for the package, for a signature code, or for a pickup code.

[0067] The signature processing module 54 is used to input the courier's pending signature tracking number, match the signature code according to the pending signature tracking number, and broadcast the signature code if the courier's requirement is for the user to sign for the courier or to need a signature code.

[0068] The return processing module 55 is used to enter the returned express tracking number if the courier requires a pickup code, match the pickup code according to the returned express tracking number, and broadcast the pickup code.

[0069] Furthermore, such as Figure 7 As shown, based on the above-mentioned express delivery processing method and system based on smart door lock, the present invention also provides a smart door lock, which includes a processor 10, a memory 20 and a display 30. Figure 7 Only some components of the smart lock are shown; however, it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

[0070] In some embodiments, the memory 20 may be an internal storage unit of the smart lock, such as a hard drive or memory. In other embodiments, the memory 20 may be an external storage device of the smart lock, such as a plug-in hard drive, smart media card (SMC), secure digital (SD) card, flash card, etc. Further, the memory 20 may include both internal and external storage units of the smart lock. The memory 20 is used to store application software and various types of data installed on the smart lock, such as the program code for installing the smart lock. The memory 20 can also be used to temporarily store data that has been output or will be output. In one embodiment, the memory 20 stores a smart lock-based express delivery processing program 40, which can be executed by the processor 10 to implement the smart lock-based express delivery processing method of this application.

[0071] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor, or other data processing chip, used to run program code stored in the memory 20 or process data, such as executing the express delivery processing method based on the smart door lock.

[0072] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an OLED (Organic Light-Emitting Diode) touchscreen. The display 30 is used to display information from the smart lock and to display a visual user interface. The processor 10, memory 20, and display 30 of the smart lock communicate with each other via a system bus.

[0073] In one embodiment, when the processor 10 executes the smart lock-based express delivery processing program 40 in the memory 20, the following steps are performed:

[0074] When the smart door lock's delivery assistant function is detected to be activated, the doorbell will be triggered or the sensor will detect the visitor and wake up the peephole for visitor identification.

[0075] If a courier is detected, the courier will be prompted via voice whether the user needs to sign for the package, whether a signature code is required, and whether a pickup code is required.

[0076] After detecting the number keys entered on the keypad of the smart door lock or recognizing the courier's voice response, it is determined whether the courier's needs are for the user to sign for the package, for a signature code, or for a pickup code.

[0077] If the courier needs the user to sign for the package or needs a signature code, the courier enters the package tracking number to be signed for, matches the signature code according to the package tracking number, and announces the signature code.

[0078] If the courier requires a pickup code, the courier enters the returned tracking number, matches the pickup code with the returned tracking number, and announces the pickup code.

[0079] Specifically, when the smart lock's delivery assistant function is detected to be activated, the doorbell is used to wake up the peephole for visitor identification based on the doorbell trigger or sensor detection.

[0080] Receive user commands to activate the courier assistant function via APP, mini-program, Internet or Bluetooth, and activate the courier assistant function according to the commands.

[0081] When the Express Assistant function is enabled, it will determine in real time whether the doorbell is triggered or the sensor is detected. If the doorbell is triggered or the sensor is detected, the Express Assistant function will be activated to wake up the peephole for visitor identification.

[0082] The process of detecting the numeric key input on the smart lock's keypad or recognizing the courier's voice response, and determining whether the courier's request is for the user to sign for the package, a signature code, or a pickup code, also includes:

[0083] Based on the user's settings in the APP or mini-program, or by linking with the courier platform, the smart lock automatically records and saves the signature codes and pickup codes of all unprocessed packages.

[0084] Specifically, entering the pending delivery tracking number involves:

[0085] The delivery tracking number can be entered by the courier typing on the keyboard, scanning the barcode on the waybill through the courier's camera, or by the courier's voice input.

[0086] The specific steps for entering the returned express tracking number are as follows:

[0087] The returned package tracking number can be entered by the courier typing on the keyboard, scanning the barcode on the waybill through a peephole, or by the courier using voice input.

[0088] Specifically, if the courier's requirement is for the user to sign for the package or for a signature code, the courier enters the tracking number to be signed for, matches the signature code based on the tracking number, and announces the signature code. This includes:

[0089] According to the courier's confirmation operation, if the courier needs the user to sign for the package or needs a signature code, the courier will enter the package number to be signed for through keyboard input, scanning the barcode on the package slip through the courier's camera, or voice input.

[0090] The system matches the pending delivery tracking number with the stored delivery code. If a matching delivery code is found, the code is broadcast so that the courier can confirm and complete the delivery signing.

[0091] Specifically, if the courier requires a pickup code, the courier enters the returned package tracking number, matches the pickup code based on the returned package tracking number, and announces the pickup code. This includes:

[0092] If the courier confirms that the courier needs a pickup code, the returned package tracking number can be entered by the courier by typing it on the keyboard, scanning the barcode on the waybill through the courier's camera, or by the courier's voice input.
