[0027] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0028] The following describes a smart door lock firmware package upgrade method, device, electronic device, storage medium and smart door according to embodiments of the present disclosure with reference to the accompanying drawings.

[0029] In the rapidly changing and developing IoT market, new product demands are constantly emerging. IoT platforms support device firmware upgrades via Over-the-Air (OTA) technology, which is a means for smart devices to repair system vulnerabilities and implement system upgrades. More and more devices require OTA upgrades to optimize firmware, so the demand for updates for smart hardware devices has become unprecedentedly high.

[0030] Over-the-Air Technology (OTA) allows users to program parts of the User Flash memory while the user is running. This allows users to easily update the firmware of a product through a reserved communication port after the product is released.

[0031] Specifically, existing solutions for modules with algorithm models are generally large (over 10MB after compression). For example, the upgrade package for a 3D face recognition module can exceed 10MB. The algorithm module is typically powered by dry-cell batteries, while the video recording module is typically powered by a lithium battery, both of which are managed by independent battery management systems. The algorithm module is connected to the microcontroller's main control chip via a serial port; OTA data packets are transmitted through the serial port to upgrade the module.

[0032] However, the smart door lock firmware package upgrade method in the existing technology is affected by factors such as the control link being too long and requiring multiple main control chips to transfer, which greatly reduces the OTA transmission efficiency.

[0033] In addition, due to the resource limitations of the microcontroller main control chip, the entire OTA data packet of the algorithm module cannot be cached, so the integrity of the OTA data packet cannot be verified.

[0034] To this end, in response to the above-mentioned problems of the prior art, the present invention proposes a method for upgrading the firmware package of a smart door lock, which controls the closure of the serial port switch through the single-chip microcomputer chip, responds to the upgrade instruction and switches the firmware package transmission path and working mode to the big data interaction mode, and uses the video main control chip to transmit the firmware package to the algorithm module at a high baud rate, reducing link transit, improving data transmission efficiency, and not being limited by the resources of the single-chip microcomputer.

[0035] The smart door lock firmware package upgrade method proposed in the present disclosure can be applied to video solutions (such as video door locks, doorbells, cat-eye devices, etc.), and the application scenarios are not limited in the embodiments of the present disclosure.

[0036] The following describes in detail with reference to the accompanying drawings a method, device, electronic device, storage medium, smart door, and program product for upgrading the smart door lock firmware package proposed in the present disclosure.

[0037] Figure 1 This is a flow chart of a method for upgrading the firmware package of a smart door lock provided by an embodiment of the present disclosure. Figure 1 As shown, the method comprises the following steps:

[0038] Step 101, in response to the upgrade instruction, the serial port switch is closed by the single-chip microcomputer chip, the firmware package transmission path is determined, and the working mode switching notification corresponding to the firmware package transmission path is sent to the video main control chip. The video main control chip and the serial port switch are both connected to the single-chip microcomputer chip.

[0039] In one implementation of the present disclosure, an upgrade instruction refers to transmitting a data set for data update. The upgrade instruction can be issued from the cloud, in other words, issued by a user via a mobile terminal app, or directly issued by a user via voice control, all of which are not limited in the present disclosure. Furthermore, the upgrade instruction can be a fixed signal set by the device at the factory. When the device recognizes the upgrade signal, it can automatically upgrade the smart door lock firmware package.

[0040] The present disclosure can control the closing of the serial port switch through the single-chip microcomputer chip, adjust the data transmission path, determine the current data transmission path as the firmware package transmission path, and realize the transmission of the firmware package. Specifically, the firmware package transmission path in the present disclosure needs to pass through the video main control chip, the switch and the algorithm module.

[0041] It is understandable that when no upgrade command is issued from the cloud, the MCU chip in the present disclosure controls the serial port switch to be turned on, and the data transmission path is the normal transmission path. This normal transmission path needs to pass through the video main control chip, MCU chip, switch and algorithm module.

[0042] Among them, in order to further improve the transmission efficiency of the firmware package in the present disclosure, the present disclosure can use the single-chip microcomputer chip to control the closing of the serial port switch, and at the same time, send a working mode switching notification corresponding to the firmware package transmission path to the video main control chip to instruct the video main control chip to switch the working mode to a working mode suitable for firmware package transmission.

[0043] Step 102: Based on the working mode switching notification, the video master chip switches the normal working mode to the big data interaction mode. The normal working mode means that the video master chip transmits data at a low baud rate, and the big data interaction module means that the video master chip transmits data at a high baud rate.

[0044] In one embodiment of the present disclosure, the video master control chip can switch from a normal low-baud-rate data transmission mode to a high-baud-rate large-data interaction mode based on a working mode switch notification, thereby achieving more efficient data transmission. This improves the transmission speed of large data such as firmware packages and optimizes system performance.

[0045] Step 103: The video main control chip transmits the firmware package to the algorithm module according to the firmware package transmission path and the big data interaction mode. The algorithm module is connected to the video main control chip through the serial port switch.

[0046] In one embodiment of the present disclosure, data transmission is performed through the video main control chip according to the adjusted data transmission path (ie, the firmware package transmission path) and the switched working mode (ie, the big data interaction mode).

[0047] It can be understood that when the working mode is the big data interaction mode, the video master chip can quickly transmit the firmware package to the algorithm module through the switch at a high baud rate; when the working mode is the normal working mode, the video master chip first transmits the data to the microcontroller chip at a low baud rate, and the microcontroller chip then transmits the data to the algorithm module through the switch to achieve the need to reduce power consumption.

[0048] Therefore, according to the embodiment of the present disclosure, by responding to the upgrade instruction, the serial port switch is controlled to be closed through the single-chip microcomputer chip, the firmware package transmission path is determined, and the working mode switching notification corresponding to the firmware package transmission path is sent to the video main control chip, and the video main control chip and the serial port switch are both connected to the single-chip microcomputer chip; based on the working mode switching notification, the video main control chip switches the normal working mode to the big data interaction mode, the normal working mode means that the video main control chip transmits data at a low baud rate, and the big data interaction module means that the video main control chip transmits data at a high baud rate; the video main chip transmits the firmware package to the algorithm module according to the firmware package transmission path and the big data interaction mode, and the algorithm module is connected to the video main control chip through the serial port switch, so that when the upgrade instruction is received, the firmware package transmission path and the working mode are switched to reduce the link transit during big data interaction, and at the same time, it is not limited by the resources of the single-chip microcomputer main control chip, thereby improving the data transmission efficiency.

[0049] Figure 2 A flowchart of a smart door lock firmware package upgrade method provided in an embodiment of the present disclosure. Figure 2 based on Figure 1 In the embodiment shown, step 101 and step 103 are further defined. Figure 2 In the embodiment shown, step 101 includes steps 201 and 202, and step 103 includes step 206. Figure 2 As shown, the method includes the following steps:

[0050] Step 201 , in response to an upgrade instruction, a baud rate mode adjustment notification is sent to an algorithm module via a single-chip microcomputer chip, and the single-chip microcomputer chip is connected to the algorithm module via a serial port switch.

[0051] In step 202 , the algorithm module adjusts the low baud rate mode to the high baud rate mode based on the baud rate mode adjustment notification, so as to receive the firmware package transmitted by the video main control chip through the algorithm module according to the high baud rate mode.

[0052] In one embodiment of the present disclosure, the present disclosure can respond to an upgrade instruction and send a baud rate mode adjustment notification to the algorithm module through the single-chip microcontroller chip. After receiving the baud rate mode adjustment notification, the algorithm module can adjust the low baud rate mode to the high baud rate mode. The baud rates of the high baud rate mode and the low baud rate mode in the present disclosure are pre-set when the device leaves the factory and are not limited in the embodiments of the present disclosure. The baud rate corresponding to the low baud rate mode in the present disclosure can be 115200bps, etc., and the baud rate corresponding to the high baud rate mode can be 1.5Mbps, 3Mbps, or even higher.

[0053] Step 203: The single-chip microcomputer chip controls the serial port switch to be closed, determines the firmware package transmission path, and sends a working mode switching notification corresponding to the firmware package transmission path to the video main control chip.

[0054] In one embodiment of the present disclosure, a serial port switch is added to the hardware architecture to determine the firmware package transmission path. The serial port switch can be a UART switch, which is not limited in this disclosure. UART stands for Universal Asynchronous Receiver / Transmitter, an asynchronous receiver / transmitter that is part of computer hardware and converts data to be transmitted between serial and parallel communication.

[0055] After the baud rate mode is adjusted to the high baud rate mode through the algorithm module, the present invention can control the serial port switch (UART switch) to be closed through the single-chip microcomputer chip, thereby obtaining the firmware package transmission path, and at the same time, the working mode switching notification corresponding to the firmware package transmission path can be sent to the video main control chip through the single-chip microcomputer chip.

[0056] That is, when the UART switch is turned on, the algorithm module is directly connected to the MCU main control chip; when the UART switch is turned off, the algorithm module is directly connected to the video main control chip, and the video main control directly sends the firmware package to the algorithm module to complete the firmware transmission, thereby improving OTA transmission efficiency.

[0057] In addition, in an embodiment of the present disclosure, the present disclosure can also determine the working status of the video main control chip and the door lock sensor respectively through the single-chip microcomputer chip, and the door lock sensor is connected to the single-chip microcomputer chip; if the single-chip microcomputer chip determines that the working status of the video main control chip and the door lock sensor are both idle, the serial port switch is controlled to close, the firmware package transmission path is determined, and the working mode switching notification is sent to the video main control chip; if the single-chip microcomputer chip determines that the working status of the video main chip is busy and / or the working status of the door lock sensor is busy, then after a preset period of time, the serial port switch is controlled to close, the firmware package transmission path is determined, and the working mode switching notification is sent to the video main control chip.

[0058] At the same time, the present invention can also receive preset idle period information; based on the preset idle period information, within the preset idle period, in response to the upgrade instruction, the serial port switch is closed through the single-chip microcomputer chip to obtain the firmware package transmission path, and the working mode switching notification is sent to the video main control chip.

[0059] Step 204: Based on the working mode switching notification, the video main control chip switches the normal working mode to the big data interaction mode.

[0060] In one embodiment of the present disclosure, when the video main control chip receives a working mode switching notification, it can switch the current normal working mode to the big data interaction mode.

[0061] Step 205: The video main control chip transmits the firmware package to the algorithm module according to the firmware package transmission path and the big data interaction mode.

[0062] In one embodiment of the present disclosure, the present disclosure may utilize a video master control chip to transmit the firmware package to an algorithm module based on the aforementioned determined firmware package transmission path and big data interaction mode.

[0063] In addition, in the embodiments of the present disclosure, the abundant resources of the video master can also be utilized. The video master chip can be connected to the server via WiFi or a wired network to ensure that the video is uploaded to the cloud service. The video master can also cache the algorithm module OTA firmware package via WiFi or a wired network and perform signature verification on it. That is, the video master chip receives the firmware package transmitted by the remote server via wireless communication, and performs signature verification on the firmware package to determine whether the firmware package is complete. If the video master chip determines that the firmware package is complete, the firmware package is transmitted to the algorithm module according to the big data interaction mode and the firmware package transmission path.

[0064] Step 206 : Send a baud rate mode adjustment notification to the algorithm module and a serial port switch opening notification to the single-chip microcomputer chip via the video main control chip, so that the algorithm module converts the high baud rate mode to the low baud rate mode and the single-chip microcomputer chip controls the serial port switch to open.

[0065] In one embodiment of the present disclosure, when the big data interaction ends, the present disclosure can use the video main control chip to notify the algorithm module to switch back to the normal working mode, and at the same time notify the low-power microcontroller to turn on the serial port switch.

[0066] To sum up, according to the embodiments of the present disclosure, it is possible to reduce link transit during big data interaction by switching between different working modes, without being restricted by the resources of the single-chip microcontroller main control chip, thereby improving data transmission efficiency. At the same time, by utilizing the rich resources of the video main control, the video main control can cache the algorithm module OTA firmware package and perform signature verification and other tasks on it to ensure the legitimacy of the OTA data packet.

[0067] based on Figure 1 、 Figure 2 In the embodiment shown, the present disclosure provides a smart door lock firmware package upgrade system, such as Figure 3 The figure shows a framework diagram of a smart door lock firmware package upgrade system provided by an embodiment of the present disclosure. Figure 4 As shown, the present disclosure also provides a framework diagram of a specific smart door lock firmware package upgrade system.

[0068] In some embodiments of the present disclosure, the system includes: an algorithm module, a video main control chip, a single-chip microcomputer chip, a serial port switch, a communication module and a cloud server; the single-chip microcomputer chip is connected to the video main control chip, and the single-chip microcomputer chip and the video main control chip are connected to the algorithm module; the serial port switch is connected to the single-chip microcomputer chip, the video main control chip and the algorithm module, and the single-chip microcomputer chip controls the closing and opening of the serial port switch; the video main control chip and the cloud server are connected through a communication module, and the communication module is used to realize remote communication between the main control module and the remote server.

[0069] Specifically, refer to Figure 4 As shown in the figure, a serial port switch (UART switch) is added to the hardware architecture to switch the UART path of the algorithm module: when the video main control chip is in normal working mode, the UART switch is turned on, and the algorithm module is directly connected to the MCU main control chip to complete the specific algorithm recognition function, namely the D->F path (UART); when executing the algorithm firmware upgrade, the UART switch is closed. At this time, the algorithm module is directly connected to the video main control chip. The video main control directly sends the firmware package to the algorithm module to complete the firmware transmission, thereby improving OTA efficiency. In other words, when the working mode is normal working mode, the downlink data flow is: A->B->C->D->F; when the working mode is big data interaction mode (algorithm module OTA upgrade), the downlink data flow is: A->B->E->F.

[0070] In summary, compared with the prior art, in the embodiments disclosed herein, the firmware upgrade time is reduced from 1 hour to less than 10 minutes. By switching different UART channels, the link transit during big data interaction is reduced, and it is not limited by the resources of the single-chip microcontroller main control chip, thereby improving data transmission efficiency. At the same time, by utilizing the rich resources of the video main control, the video main control can cache the algorithm module OTA firmware package and perform signature verification and other tasks on it to ensure the legitimacy of the OTA data packet.

[0073] A switching unit 520 is configured to switch the normal working mode to the big data interaction mode based on the working mode switching notification of the video main control chip.
