[0033] TLS, Transport Layer Security, Transport Layer Security Protocol.

[0034] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the present application provides a method for upgrading a phenotypic Internet of Things program, wherein the phenotypic Internet of Things program is applied to a phenotypic Internet of Things device, wherein the phenotypic Internet of Things program includes: a boot program and multiple application programs, the number of which is at least two. The method for upgrading the phenotypic Internet of Things program mainly implements OTA online upgrading.

[0036] like Figure 1 As shown, the method includes:

[0037] Step 101, after the phenotypic IoT device is powered on, a boot program is run, and a boot address of a target application to be run is read from a parameter storage area using the boot program, the target application is called through the boot address, and the target application is run, wherein the target application belongs to any one of a plurality of applications.

[0038] In specific implementation, the boot program has the function of booting and starting, can determine the target application to be started, and directly read the startup address of the target application from the parameter storage area, so as to achieve the purpose of running the target application. The boot program can well realize the control and operation of multiple applications, and the operation is simple and convenient.

[0039] Step 102, during the operation of the target application, a firmware data packet to be upgraded of the phenotype IoT program sent by the IoT cloud platform is received, wherein one firmware data packet to be upgraded corresponds to one new application.

[0040] In specific implementation, during the operation of the target application, if a firmware data packet to be upgraded of a phenotype IoT program sent by the IoT cloud platform is received, some identity information of the firmware data packet to be upgraded will be obtained before downloading.

[0041] Step 103, in response to the firmware data packet to be upgraded meeting the upgrade rule, determining the startup address of the new application corresponding to the firmware data packet to be upgraded, downloading the firmware data packet to be upgraded, and writing the firmware data packet to be upgraded into the startup address of the corresponding new application.

[0042] In the specific implementation, the identity information of the firmware data packet to be upgraded is determined using the corresponding upgrade rules. If it does not meet the requirements, the upgrade process is stopped. If it meets the requirements, the corresponding startup address will be determined for the new application. In this way, after the firmware data packet to be upgraded is downloaded, the firmware data packet to be upgraded can be better written according to the startup address, so that the new application can be read, started and run according to the startup address later.

[0043] Step 104, add the startup address of the new application to the application address index variable in the parameter storage area, determine that the initial upgrade of the phenotypic IoT program is completed, and restart.

[0044] In specific implementation, in order to facilitate the boot program to read the startup address of the new application, the startup address of the new application will be added to the application address index variable in the parameter storage area, thereby realizing the association with the boot program. This completes the initial upgrade process on the side of the phenotypic IoT device.

[0045] Step 105, the authentication information of the new application after restart is sent to the IoT cloud platform, so that the IoT cloud platform can judge the authentication information and determine whether the authentication information matches the firmware data packet to be upgraded of the sent phenotypic IoT program, and after determining the match, the phenotypic IoT program is upgraded successfully.

[0046] In specific implementation, after the initial upgrade of the phenotypic IoT device is completed, it is restarted and the authentication information of the upgraded new application can be sent to the IoT cloud platform for verification to determine whether the upgrade is successful. If the upgrade is successful, the upgraded new application can be used. If the upgrade is unsuccessful, the above steps 102 to 105 will be executed again for re-upgrade.

[0047] Through the above scheme, the phenotype Internet of Things program will be divided into a boot program and multiple applications, so that the boot program can be used to read the startup address of the target application to be run from the parameter storage area, and the target application is called through the startup address, so as to achieve the purpose of running the target application. During the operation, after receiving the firmware data packet to be upgraded of the phenotype Internet of Things program sent by the Internet of Things cloud platform, the firmware data packet to be upgraded will be automatically judged to determine whether it meets the corresponding upgrade rules. If it meets the rules, the startup address of the corresponding new application will be determined, and then the firmware data packet to be upgraded will be downloaded. After the download is completed, the firmware data packet to be upgraded will be written to the startup address of the corresponding new application; then the startup address of the new application will be added to the application address index variable in the parameter storage area, so as to complete the initial upgrade of the phenotype Internet of Things program, and then the phenotype Internet of Things program will be restarted. After restarting, the authentication information of the new application will be obtained and sent to the Internet of Things cloud platform; finally, after the Internet of Things cloud platform determines that the authentication information matches the firmware data packet to be upgraded of the sent phenotype Internet of Things program, it can be determined that the upgrade is successful. This process does not require human intervention and is simple and convenient to operate. It can enable the phenotypic IoT device to automatically upgrade when it is unattended for a long time, and continue to work after the upgrade, ensuring the continuity of the operation of the phenotypic IoT device during the upgrade process without affecting the collection or analysis of phenotypic data.

[0048] In some embodiments, in response to the firmware data packet to be upgraded meeting the upgrade rule in step 103, the step includes:

[0049] Step 1031, obtaining the first device name and the first product key value in the firmware data packet to be upgraded.

[0050] Step 1032, comparing the first device name with the second device name of the phenotypic IoT device.

[0051] Step 1033, comparing the first product key value with the second product key value of the phenotypic IoT device.

[0052] Step 1034, determine that the first device name matches the second device name, and the first device name matches the second device name, and obtain the version number in the firmware data packet to be upgraded.

[0053] During specific implementation, the first device name and the first product key value are checked. If they match the second device name and the second product key value of the phenotypic IoT device respectively, it is determined that the firmware data packet to be upgraded is for the phenotypic IoT device, and the version number in the firmware data packet to be upgraded is obtained for further inspection.

[0054] Step 1035: Determine whether the version number in the firmware data package to be upgraded satisfies the upgrade rule.

[0055] In the specific implementation, the version number in the firmware data package to be upgraded is compared with the pre-set upgrade rules. If the upgrade rules are met, the firmware data package to be upgraded is acceptable and the next step of upgrade preparation is entered. In this way, if any of the name, key value, and version number does not match, the upgrade will be stopped.

[0056] Through the above solution, the name, key value, and version number can be compared and checked layer by layer, thus ensuring the accuracy of the upgrade process.

[0057] In some embodiments, step 1035 includes:

[0058] Step 10351, obtaining first digital information of the last predetermined number of digits (for example, the last 3 digits) in the version number of the firmware data packet to be upgraded, and determining the parity of the first digital information.

[0059] Step 10352, obtain the second digital information of the last predetermined number of digits (for example, the last 3 digits) in the version number of the current phenotypic IoT program, and determine the parity of the second digital information.

[0060] Step 10353: In response to the parity of the first digital information being different from the parity of the second digital information, determining that an upgrade rule is satisfied.

[0061] In a specific implementation, if the first digital information is an odd number and the second digital information is an even number, or if the first digital information is an even number and the second digital information is a random number, the upgrade rule will be met.

[0062] Through the above scheme, using parity for judgment can better ensure that the firmware data packet to be upgraded is a different version of the currently running phenotype IoT program and needs to be upgraded before the upgrade process is executed, thereby ensuring the accuracy of the upgrade process.

[0063] In some embodiments, determining the startup address of the new application corresponding to the firmware data packet to be upgraded in step 103, downloading the firmware data packet to be upgraded, and writing the firmware data packet to be upgraded into the startup address of the corresponding new application includes:

[0064] Step 103a, determining index data of the new application in the internal storage area of ​​the phenotypic IoT device.

[0065] Step 103b: Determine the startup address of the new application based on the index data of the new application.

[0066] Step 103c, downloading the firmware data package to be upgraded, and writing the firmware data package to be upgraded into the corresponding startup address.

[0067] During specific implementation, in order to ensure that the firmware data packet to be upgraded can run normally, the index data of the internal storage area of ​​the phenotype IoT device will be determined for the corresponding new application, so that the startup address of the new application can be determined based on the index data, and then the firmware data packet to be upgraded after downloading is written into the startup address of the new application, so that it can be associated with the boot program.

[0068] In addition, if Figure 2 As shown, the phenotypic IoT device and the IoT cloud platform are encrypted via TLS. Specifically, the MCU of the phenotypic IoT device interacts with the communication module via the serial port using TLS encrypted transmission, and the communication module interacts with the IoT cloud platform via wired and / or wireless TLS encrypted transmission. This ensures the correctness of the firmware data packet to be upgraded received by the phenotypic IoT device, and when downloading the firmware data packet to be upgraded, it can ensure that each sub-data packet of the received firmware data packet to be upgraded is correct.

[0069] Through the above scheme, the corresponding startup address can be determined for the firmware data packet to be upgraded, and then written into the startup address of the corresponding new application, so as to realize the association between the new application and the boot program. In this way, if the boot program wants to start the new application later, it can directly read the corresponding startup address to call the corresponding new application to start running, which is convenient and quick to operate.

[0070] In some embodiments, step 103a includes:

[0071] Step a1, determining the initial index data of the target application running in the phenotypic IoT device in the internal storage area of ​​the phenotypic IoT device , the specific formula is:

[0072] ,in, is the actual startup address of the target application running in the phenotype IoT device, The base address of the application area in the internal storage area of ​​the phenotype IoT device. The amount of space of the storage block corresponding to each application divided in the internal storage area of ​​the phenotypic IoT device;

[0073] Step a2, based on the initial index data , determine the index data of the new application in the internal storage area of ​​the phenotypic IoT device , the specific formula is:

[0074]

[0075] in, is the version number of the current phenotype IoT program, is the version number of the firmware data package to be upgraded, and N is the number of memory blocks in the internal storage area of ​​the phenotypic IoT device used to store application programs. The internal storage area of ​​the MCU of the phenotypic IoT device is divided as follows: Figure 3 shown.

[0076] Through the above solution, the index data can be accurately calculated, which facilitates the subsequent determination of the startup address based on the index data.

[0077] In some embodiments, step 103b includes:

[0078] Step b1, determining the amount of space of the storage block corresponding to each application divided in the internal storage area of ​​the phenotypic IoT device .

[0079] Step b2, determining the base address for storing the application area in the internal storage area of ​​the phenotypic IoT device .

[0080] Step b3, index data of the new application in the internal storage area of ​​the phenotypic IoT device The amount of space associated with the storage block Multiply to obtain a multiplication result, and add the multiplication result to the base address Add together to get the startup address of the new application .

[0081] When implementing, the startup address of the new application The corresponding formula is: .

[0082] Through the above scheme, the startup address of the new application can be accurately calculated .

[0083] In some embodiments, downloading the firmware data package to be upgraded in step 103 includes:

[0084] Step S1, erasing the flash memory area corresponding to the firmware data package to be upgraded.

[0085] Step S2, downloading the firmware data package to be upgraded in sub-packages according to the preset sub-package space amount.

[0086] Step S3: each time a sub-data package is downloaded, the downloaded sub-data package is placed in the flash memory area.

[0087] Step S4, comparing the sub-data package put into the flash memory area with the downloaded sub-data package to obtain a comparison result.

[0088] Step S5, in response to the comparison result being successful, determining that the sub-data package placed in the flash memory area is correct, continuing to download the next sub-data package of the firmware package to be upgraded until all sub-data packages in the firmware package to be upgraded are downloaded.

[0089] Alternatively, in step S6, in response to the comparison result being a comparison failure, the upgrade process of the firmware data packet to be upgraded is terminated, and the upgrade process is restarted. After the restart, the firmware data packet to be upgraded sent by the IoT cloud platform is received again, and the process returns to the step of downloading the sub-packets according to the preset sub-packet space until all sub-packets in the firmware data packet to be upgraded are downloaded.

[0090] Through the above solution, the download process of the firmware data package to be upgraded can be ensured to be completed smoothly, and the accuracy of the downloaded firmware data package to be upgraded can also be ensured.

[0091] The following is a specific description of the phenotypic IoT program upgrade method using an embodiment in which the number of application programs N is 2:

[0092] 1. Division of FLASH storage area inside the MCU of phenotypic IoT devices

[0093] When N=2, the internal FLASH storage area of ​​the microcontroller is divided into four parts, namely the boot program storage area, parameter storage area, application storage area 1, and application storage area 2. Figure 4 As shown:

[0094] 2. Validity determination of the firmware data package to be upgraded

[0095] Assume that there is a phenotypic IoT device that can work normally. The boot program storage area of ​​the FLASH inside the microcontroller stores the boot program, the parameter storage area stores the parameters required for the normal operation of the device, and the application storage area 1 stores the application, whose version number is V1.00.001. In order to add a certain function to the device, it is decided to initiate an OTA remote upgrade from the IoT cloud platform. The version number of the firmware data package to be upgraded is V1.01.001.

[0096] According to the validity judgment method of the firmware data package to be upgraded, the program version currently running on the phenotypic IoT device is V1.00.001, and the last three digits of its version number are odd numbers. Therefore, the last three digits of the version number of the next valid and upgradeable firmware data package to be upgraded should be even numbers. In this embodiment, the version number of the firmware data package to be upgraded pushed by the IoT cloud platform is V1.01.001, and the last three digits of its version number are odd numbers. Since it does not meet the upgrade rules, when the phenotypic IoT device receives the upgrade message pushed by the IoT cloud platform, it will not perform OTA upgrade.

[0097] Similarly, suppose that the above-mentioned phenotypic IoT device has a program BUG and needs to be repaired. Therefore, it is necessary to push the repaired program firmware from the IoT cloud platform to the phenotypic IoT device. Assuming that the version number of the firmware is V1.01.002, since the last three digits of the version number of the firmware to be upgraded are even numbers, it meets the rules described in 3.1. Therefore, when the phenotypic IoT device receives the OTA upgrade of the firmware pushed by the IoT cloud platform, it will determine that the firmware to be upgraded is a valid firmware and prepare for the next step of upgrading.

[0098] 3. Determination of the storage area of ​​the firmware data package to be upgraded

[0099] If the version number of the program currently running on the phenotypic IoT device is V1.00.001, and the last three digits are odd numbers, when the phenotypic IoT device receives a firmware data packet with version number V1.01.002 pushed to it by the IoT cloud platform, since the last three digits are even numbers, it will be determined that the firmware data packet to be upgraded complies with the upgrade rules and is a valid and upgradeable firmware data packet, and the storage area required to be burned for the firmware data packet to be upgraded will be further calculated.

[0100] According to the storage area allocation strategy of the firmware data package to be upgraded, it can be calculated that the firmware to be upgraded that passes the validity check will be burned into the application storage area 2.

[0101] Assuming that the version number of the target application currently running on the phenotypic IoT device is V1.01.002, and the application is stored in application storage area 2, then when the phenotypic IoT device receives the firmware data packet to be upgraded with version number V1.02.005 pushed by the IoT cloud platform, the phenotypic IoT device will determine that the firmware data packet to be upgraded is a valid and upgradeable firmware data packet, and according to the formula given in the above embodiment, calculate that the storage area required to burn the firmware data packet to be upgraded is application storage area 1.

[0102] 4. Download the firmware package to be upgraded

[0103] After the phenotypic IoT device calculates the storage area to be burned for the firmware to be upgraded (assuming that the calculated storage area to be burned is application storage area 2), it will perform the following operations:

[0104] 1. Erase the application storage area 2 of the FLASH inside the microcontroller.

[0105] 2. Set the size of each downloaded data packet to 1024 bytes.

[0106] 3. Write the received 1024 bytes of data into application storage area 2 in sequence.

[0107] 4. Read the 1024 bytes of data written in step 3 from the FLASH inside the microcontroller, and compare the read data with the data written in step 3.

[0108] 5. If all the data are the same, the data is written correctly, and the next 1024-byte data packet is requested from the IoT cloud platform, and the download progress of the firmware data packet to be upgraded is reported to the IoT cloud platform.

[0109] 6. If the data comparison shows a discrepancy, it is determined that the firmware data packet to be upgraded has failed to be written, the current upgrade process is terminated, and the phenotypic IoT device is restarted.

[0110] 7. After restarting the phenotypic IoT device, repeat steps 3 to 5 until the firmware data package to be upgraded is downloaded.

[0111] According to the above steps, after the download of the entire firmware to be upgraded is completed, the data of the firmware to be upgraded has been written into the internal FLASH of the microcontroller. Since the data interaction between the phenotypic IoT and the IoT cloud platform is encrypted by TLS, it can be guaranteed that every firmware data packet to be upgraded received by the phenotypic IoT device is correct. In addition, in the process of writing the firmware data packet to be upgraded into the internal FLASH of the microcontroller, the written data is compared with the read data to ensure that the written firmware data packet to be upgraded is correct.

[0112] 5. Firmware upgrade success judgment

[0113] When the phenotypic IoT device has downloaded all the data of the firmware data package to be upgraded and successfully written the firmware data package to be upgraded into the FLASH inside the microcontroller, it will update the application startup address in the parameter storage area of ​​the FLASH inside the microcontroller and then restart. When the phenotypic IoT restarts, it will retrieve the latest application startup address, jump to the latest application startup address, and execute the corresponding program code. After restarting, the phenotypic IoT device will report the version number of the currently running target application to the IoT cloud platform. The IoT cloud IoT cloud platform determines whether the OTA upgrade of the phenotypic IoT device is successful based on this.

[0114] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or an IoT cloud platform. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
