The client APP 100 may be installed on a terminal device, such as a mobile phone, a tablet computer, and the like. The client APP100 has a firmware upgrade module, which can actively detect whether a new version is available on the server. When a new version is available, it will prompt the user that there is a new firmware version, and at the same time show the user the version number and new functions of the current firmware. The function can include the function introduction of this upgrade and the modified problems, for example, the new function is the newly added remote unlock function and the solution of running bugs. Users can issue firmware upgrade instructions through the client APP100.

The cloud 200 can also issue door lock instructions, such as an instruction to control the opening or closing of the door lock, or receive status information of the smart door lock 400 under its control reported by the wireless/wired gateway in the network device 300 .

The network device 300 may include a wireless/wired gateway and a router/switch, and the wireless/wired gateway may communicate with the router/switch through WiFi or wired, and establish a ZigBee network, and deliver the data to the ZigBee module of the smart door lock 400 through the ZigBee network Door lock instruction, or receive the status information reported by the smart door lock 400 , and transmit the status information to the cloud 200 .

The smart door lock 400 may include a ZigBee module, a door lock mainboard and a camera module. The ZigBee module, the door lock mainboard and the camera module communicate through a uart serial port, and the ZigBee module is used to communicate with the network device 300 to obtain the network device 300 The issued door lock command, and the door lock command is sent to the door lock main board through the uart serial port, and the status information of the door lock main board or the camera module is received through the uart serial port, and reported to the wireless/wired gateway in the network device 300. If the door lock command is to control the camera module, the door lock motherboard sends the door lock command to the camera module through the uart serial port. The camera module is used to download the firmware upgrade information from the cloud through the WiFi network, and send the firmware upgrade information to the door lock main board through the uart serial port, and also transmit the status information of the camera module to the door lock main board through the uart serial port. Make the door lock motherboard send the status information to the ZigBee module through the uart serial port.

After the upgrade service module passes the verification of the firmware data package according to the data check code, the downloaded firmware upgrade information can be sent to the firmware receiving module of the motherboard through the UART serial port.

It should be noted that the structure shown in FIG. 1 above is only an example, which is not limited in this embodiment of the present invention.

Based on the above description, FIG. 2 shows in detail a flow of a method for upgrading the firmware of a smart door lock provided by an embodiment of the present invention, and the procedure may be executed by an apparatus for upgrading the firmware of a smart door lock. The firmware upgrade process will be described below through the interaction between the main control chip and the camera module.

As shown in Figure 2, the process specifically includes:

Step 201, after acquiring the firmware upgrade instruction issued by the client APP, the camera module downloads the firmware upgrade information of the new version from the cloud through the WiFi module.

In this embodiment of the present invention, the firmware upgrade information may include a firmware data packet and a data check code. The firmware upgrade instruction is issued by the client APP through the cloud when the user confirms that a new version of the firmware is currently available. Before receiving this instruction, the camera module will be turned on after receiving the wake-up instruction and sent to the client APP. Wake-up success message. First, the client APP sends a wake-up command to the camera module. After the camera module receives the wake-up command, it is in a working state, and sends a successful wake-up response message to the client APP. After the client APP receives the wake-up successful response message, Send firmware upgrade instructions to the camera module through the cloud.

The user can use the client APP to detect whether a new version of firmware currently exists in the cloud, and if so, can issue a firmware upgrade instruction. Due to power consumption, the camera module is in a standby state, and the camera module needs to be woken up first. The camera module will return the wake-up successful status to the client APP, and the client APP will issue a firmware upgrade instruction to the camera module according to the wake-up successful status. .

After the camera module receives the firmware upgrade instruction issued by the client APP, it starts the upgrade service module, opens the cloud service connection, and downloads the firmware upgrade information of the new version. The cloud service connection refers to connecting to the firmware file and upgrade server in the cloud in the cloud.

Since the camera module itself can access the network through the WiFi module to send the camera video stream to the client APP through the cloud, the upgrade service module can easily reuse the WiFi module and interface for server connection and authentication in the cloud. Among them, the server connection in the cloud refers to connecting to the firmware file and upgrade server in the cloud. At the same time, based on the WiFi communication protocol, the transmission rate is high, and the retransmission and verification mechanism is provided, which can realize the transmission of firmware upgrade information efficiently and safely, which solves the shortcomings of the ZigBee protocol for large data transmission.

Since the download of firmware upgrade information is realized by multiplexing the WiFi module, in the process of downloading the firmware upgrade information, the video stream collected by the camera module cannot be sent to the cloud through the WiFi module. , the video stream can be sent.

Step 202, after the camera module verifies the firmware data package according to the data verification code and passes the verification, sends the firmware upgrade information to the main control chip.

Optionally, if the camera module fails to verify the firmware data package according to the data check code, it will send a download failure message to the cloud and request retransmission, and after determining that the number of retransmissions is greater than the second threshold, confirm that the firmware upgrade failed. , and feedback the upgrade failure message to the client APP through the cloud. The second threshold can be set empirically.

When the firmware upgrade information is downloaded, first use the data check code to check the integrity of the firmware data package in the firmware upgrade information based on the MD5 hash algorithm. Only after the verification is successful, the subsequent firmware upgrade operation can be continued. Otherwise, a download failure message will be reported. , request retransmission, and set the number of times. When the retransmission exceeds the set number of times, it is determined that the upgrade has failed, and the upgrade failure message is fed back to the client APP through the cloud.

When the firmware data packet verification is successful, the upgrade service module transmits the firmware upgrade information to the firmware receiving module of the door lock mainboard through the UART serial port, and the firmware receiving module completes the receiving of the firmware upgrade information and saves the firmware upgrade information in the memory, so that the firmware can be upgraded During the operation, the firmware upgrade information is read from the memory for burning.

Step 203, the main control chip verifies the firmware data packet according to the data verification code.

The main control chip obtains the firmware upgrade information sent by the camera module. The integrity of the firmware data packet can be checked according to the MD5 check using the data check code. If it is determined that the verification of the firmware data package fails, feedback to the camera module and request for retransmission.

It should be noted that the firmware receiving module of the main control chip will receive the firmware upgrade information according to the agreed baud rate and parity after detecting the interrupt message that the UART serial port has data. The working mode of the device will be affected, so in the process of receiving the firmware upgrade information, the main control chip will actively display the prompt information on the display screen "The door lock firmware is being downloaded and upgraded, please perform the door lock operation later...", as shown in Figure 3.

When the firmware receiving module of the main control chip completes the reception of the firmware upgrade information, it first uses the data check code to check the data integrity of the firmware data packet according to MD5. , and continue with subsequent upgrade operations.

Step 204: After confirming that the verification is passed, the main control chip burns the firmware data package that has passed the verification to the Flash.

Before the main control chip burns the verified firmware data package to Flash, it needs to judge whether the current power is greater than the first threshold, and if so, perform firmware upgrade and display firmware prompt information to the user through the display screen, otherwise, pause The firmware is upgraded and the warning message of the current low battery is displayed to the user through the display screen, as shown in Figure 4. The first threshold may be set empirically, for example, the first threshold may be 10%. The firmware upgrade of the main control chip refers to burning the firmware data package into the Flash.

The erasing service of the main control chip reads the verified firmware data package from the memory, and then burns the verified firmware data package into the Flash. This process is realized by erasing, that is, flashing the Flash. The original firmware data package is erased, and then the new version of the firmware data package is written into the Flash. Due to the high safety requirements of this process, the system power required for the upgrade needs to be guaranteed. Therefore, it is necessary to judge whether the current power meets the upgrade requirements, and after confirming that the upgrade requirements are met, the screen prompts the user not to power off or do other operations, as shown in Figure 5 shown.

In addition, after burning the verified firmware data package into Flash, the main control chip shows the user the prompt information of the completion of the firmware upgrade through the display screen, and controls the camera module and the display screen to enter the standby state after a preset time. . The preset time can be set empirically. In order to achieve low power consumption, it is necessary to control the camera module and the display screen to enter the standby state.

That is to say, when the firmware upgrade is completed, the main control chip displays "Firmware upgrade complete, version number 2020.01.01" on the display screen, as shown in Figure 6. And the camera module and the display screen are automatically turned off after a specified time delay in standby, and the camera module and the display screen enter a low-power standby state.

The above embodiment shows that the main control chip of the smart door lock obtains the firmware upgrade information sent by the camera module of the smart door lock, the firmware upgrade information includes the firmware data package and the data check code, and the firmware upgrade information is the user confirming that there is a new version currently. When the firmware is available, the firmware upgrade instruction is issued to the camera module through the client APP, and the camera module downloads it from the cloud through the WiFi module, and the firmware data package is verified according to the data verification code. After the verification is passed, the firmware data package that has passed the verification is burned into the Flash. Through the WiFi module in the camera module of the smart door lock to download firmware from the cloud and upgrade the firmware, it can provide the security and upgrade efficiency of firmware upgrade, reduce the cost of firmware upgrade, and eliminate the need for staff to upgrade on-site, improving user experience.
