The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] See also Figure 1 , a flow chart of a FOTA upgrade stress test method provided in this application. The FOTA upgrade stress test method includes:

[0035] S10: Run the test tool, read the FOTA file, and divide the FOTA file into sub-files.

[0036] Testing tools are a collection of various tools and techniques used to verify whether software, hardware, networks, or other systems work as expected. They can help testers identify and fix defects, vulnerabilities, and performance issues. They can be used for automated testing, performance testing, security testing, compatibility testing, user interface testing, etc. Testers prepare the files to be upgraded in advance. After the files to be upgraded are successfully prepared, testers run the testing tools, and the testing tools upgrade the files.

[0037] FOTA (Firmware Over-The-Air) is a technology that provides firmware upgrade services for devices with networking functions through wireless networks. Testers can obtain smart terminal system upgrade packages through the network in a personalized and easily scalable way, and perform cloud upgrades through FOTA to complete system repairs and function optimization.

[0038] The test tool includes a user interface, on which the tester can configure the upgrade times to upgrade the FOTA file. The upgrade times are configured according to the needs of the tester, and a single function upgrade verification or repeated upgrade verification can be performed, saving test time and improving test efficiency.

[0039] In this embodiment, the Python OS module 110 lists the FOTA files in the current directory, reads the FOTA files in binary mode, and divides the FOTA files into sub-files of a fixed size of 1024 bytes, wherein the last package of sub-files is generated according to the size of the FOTA file.

[0040] Preferably, the Python OS 110 module lists the FOTA files in the current directory, and may use the os.listdir() function. Then, the FOTA files are read in binary format.

[0041] Split the FOTA file into sub-files of a fixed size of 1024 bytes. Binary operations can be easily performed, and 1024 bytes (1KB) is a reasonable data block size suitable for most application scenarios. In wireless network transmission, smaller data blocks are generally more efficient than large data blocks. This is because small data blocks can be retransmitted faster when problems are encountered during transmission, reducing waiting time. When processing large files, a large amount of memory resources may be occupied. Splitting files into small blocks can reduce memory usage, allowing devices to process data more efficiently, especially on embedded devices with limited memory resources. During the FOTA update process, if the update is interrupted, it can continue from the last successful data block instead of starting from the beginning, which improves the reliability of the update.

[0042] The FOTA file is split into sub-files of fixed 1024-byte size, which can be achieved by reading each 1024-byte block of the file and writing it into a new sub-file. The size of the final sub-file is generated according to the size of the FOTA file.

[0043] For example, if the size of the FOTA file is 4830 bytes, then five sub-files are generated, of which four sub-files are 1024 bytes in size and the last sub-file is 734 bytes in size.

[0044] Optionally, the FOTA file may be segmented into other power-of-two forms, such as 256 bytes, 512 bytes, 2048 bytes, etc. The specific block size may be adjusted according to actual needs.

[0045] Splitting the FOTA file can reduce the amount of data transmitted in a single transmission, which is especially important for transmission in wireless environments, because wireless networks often have limited and unstable bandwidth. The split sub-files can be transmitted in parallel, improving the overall transmission efficiency, especially in poor network conditions or when bandwidth is limited.

[0046] S20: Read each sub-file, combine the sub-files according to the station area fusion terminal protocol and generate a first protocol frame.

[0047] The area integration protocol refers to the communication technology specification used to regulate the distributed photovoltaic access integration terminal on the area side in the smart grid. The area integration terminal protocol stipulates the communication architecture and key equipment of the distributed photovoltaic access area integration terminal. The communication requirements mainly involve two aspects: the distributed photovoltaic station side and the integration terminal side, and stipulate the communication method and the standard specifications that need to be met.

[0048] The first protocol frame is a protocol frame generated by combining sub-files according to the station area fusion terminal protocol regulations, and is composed of a length field, a control field, and a data field. The length of the length field is read according to the file size; the data field is the data of each sub-file.

[0049] Reading each subfile, combining the subfiles according to the area fusion terminal protocol and generating the first protocol frame is based on the area side distributed photovoltaic access fusion terminal communication technical specifications, and it is necessary to ensure that data transmission follows the established communication architecture and requirements. This means that during data transmission, the data must be formatted according to the prescribed protocol to ensure that the data can be correctly received and parsed. By combining subfiles into protocol frames, the integrity and correctness of the data can be ensured. The generation of protocol frames allows data to be transmitted in frames, which helps to improve the efficiency of data transmission. At the receiving end, data can be processed quickly by identifying the specific format of the protocol frame without reorganizing the data stream. The area fusion terminal may need to transmit data through different communication media (such as power lines, wireless, etc.). Combining subfiles into protocol frames ensures that the data can adapt to different communication media and environments.

[0050] The Python OS module 110 traverses the generated sub-files, and then reads each sub-file in turn, combines the read sub-file data according to the specific specifications of the station area fusion terminal protocol, and then generates a complete protocol frame according to the protocol specification.

[0051] Read each subfile, combine the subfiles according to the area fusion terminal protocol and generate the first protocol frame to ensure that all subfiles are combined according to the unified area fusion terminal protocol, realize standardized communication process, and improve the compatibility and interoperability of the system. At the same time, through the combination of protocol frames, the integrity of data during transmission is ensured, and errors caused by data loss or damage are reduced. And through the reasonable framing of protocol frames, the transmission of invalid data can be reduced and the efficiency of data transmission can be improved.

[0052] Before the step of reading each of the sub-files, combining the sub-files according to the station area fusion terminal protocol and generating a first protocol frame, the step further includes:

[0053] S21: List the serial ports of the test tool, find the control port, return and open the control port.

[0054] The control port is a port used for management and control. In this embodiment, the control port is used for data exchange between the Python OS module 110 and the communication module 120 to transfer protocol frames.

[0055] By listing the serial ports of the test tool and finding the control port, device testing and data monitoring can be easily performed, improving test efficiency and accuracy, and an intuitive user interface can be provided so that non-professionals can easily perform serial port communication and device control. Supporting the use of virtual serial ports increases the flexibility and application scope of the test tool. The process of listing serial ports, finding the control port and opening the control port not only improves the efficiency of testing and communication, but also enhances the reliability and flexibility of the system.

[0056] S30: The first protocol frame is packaged according to the file system table and the verification algorithm to generate a second protocol frame.

[0057] File system tables are a set of data structures used to maintain file system structure and data in computer file systems. These tables contain metadata of all files and directories in the file system, as well as the location information of file data blocks on storage devices.

[0058] Checksum algorithms are methods used to detect and correct errors that occur during data transmission or storage. These algorithms achieve error detection and / or correction by adding redundant information to the data.

[0059] The second protocol frame is generated by the first protocol frame according to the file system table and the verification algorithm, and is composed of a start marker, a length field, a control field, a data field, a frame check sequence (FCS) and an end marker. The start marker helps the receiving device determine the starting position of the data frame and synchronizes the receiving clock. In different communication protocols and data formats, the length of the start marker may be different. In this embodiment, the length of the start marker is 68. The length of the length field, the length and reserved bits of the control field, and the data content of the data field are the same as those of the first protocol frame.

[0060] The frame check sequence is a verification mechanism used to detect whether errors occur during data transmission. The frame check sequence is a binary code added at the end of the data frame, usually calculated using a cyclic redundancy check algorithm. After receiving the data frame, the receiver will recalculate the frame check sequence value and compare it with the frame check sequence value in the data frame to verify the integrity of the data.

[0061] The terminator is used to identify a specific character or character sequence at the end of a data frame or message. Its function is to help the receiving device determine the boundary of the frame and ensure the integrity and correctness of the data. The use of the terminator is very important for both synchronous and asynchronous communication. In this embodiment, the length of the terminator is 16.

[0062] The data length of the second protocol frame is the sum of the data length, the start marker, the frame check sequence and the end marker length of the first protocol frame.

[0063] The first protocol frame is packaged according to the file system table and the verification algorithm to generate the second protocol frame, making the generated protocol frame more accurate, improving the accuracy of the data, and improving the reliability of the system. And this process is completely completed by the test tool, reducing the difficulty of manual subpackaging, framing, and calculating the frame verification sequence.

[0064] S40: The second protocol frame is sent to the communication module through the control port. After the second protocol frame is sent, the communication module is upgraded.

[0065] After the second protocol frame is sent to the communication module through the control port, the upgrade function of the test tool is triggered, and the upgrade function automatically upgrades the communication module. This solution can upgrade the communication module without a network, which is particularly important for scenarios that require upgrades in remote or network-unreachable environments. In addition, this solution can realize remote upgrades. By remotely / pre-configuring the upgrade information, the upgrade can be automatically started when the second protocol frame is received, without the need for personnel to go to the site, saving manpower.

[0066] The second protocol frame is sent to the communication module through the control port. After the second protocol frame is sent, the communication module automatically upgrades by sending the protocol frame in an automated manner and triggering the upgrade, which reduces manual intervention and improves the efficiency and reliability of the upgrade process. In addition, remote upgrades reduce the need for on-site maintenance, save labor costs and time costs, and improve upgrade efficiency. Remote upgrades can be performed anytime and anywhere without physical connection, which is convenient and fast.

[0067] The second protocol frame is sent to the communication module through the control port. After the second protocol frame is sent, after the step of automatically upgrading the communication module, the step further includes:

[0068] S41: The communication module automatically restarts after successful automatic upgrade.

[0069] The communication module automatically restarts after a successful upgrade to load the new firmware version, so that the upgraded changes are immediately applied to the module.

[0070] The automatic restart of the communication module after a successful upgrade ensures that it can be restarted accurately when the communication module has a program error or anomaly, avoiding the communication module from being in a dead state, thereby improving the security and applicability of communication. The communication module automatically restarts after a successful upgrade, reducing manual intervention, realizing automated intelligent operation and maintenance, and improving operation and maintenance efficiency. In addition, users can remotely enjoy the functions and performance of the latest version without manually restarting the device, which improves the user experience.

[0071] S42: Determine the number of upgrades, and if the number of upgrades is greater than 1, run the test tool again.

[0072] The upgrade times are preset by the tester on the user interface of the test tool. The Python OS module reads the upgrade times and performs loop testing based on the upgrade times. Through loop testing, it can ensure that each upgraded version has been fully tested, increase test coverage, and help discover potential problems.

[0073] By executing test tasks in parallel, test efficiency can be improved and test time can be shortened. Reasonable division of the test scope, such as division by functional modules, executing test tasks for each module separately, and performing multi-threaded testing at the same time can improve test efficiency and reduce test pressure.

[0074] After the communication module automatically restarts, the upgrade times set by the tester are determined. If the upgrade times are greater than 1, the test tool is run again and the test steps are repeated until the upgrade times set by the tester are completed. This solution can flexibly perform single function upgrade verification or repeated upgrade verification according to the tester's configuration. It saves test time and improves test efficiency.

[0075] S43: If the number of upgrades is 1, then the running of the test tool ends.

[0076] The tester sets the upgrade count to 1, and the test tool performs a test on the file. After a test is completed, the communication module automatically updates and restarts, completing the entire test process.

[0077] The testing tool can flexibly adjust the testing process according to the number of upgrades, improving the tool's adaptability and user experience.

[0079] The FOTA upgrade stress test system 100 includes a Python OS module 110 and a communication module 120 to be upgraded. The Python OS module 110 is in communication connection with the communication module 120 .

[0080] The Python OS module 110 provides many functions for interacting with the operating system, including file and directory operations, environment variable management, process management, etc., and upgrades the communication module 120 through the FOTA upgrade stress testing method.

[0081] In this embodiment, the FOTA upgrade stress testing system 100 can support the testing and verification of 3G communication, 4G communication, and 5G communication of the station integrated terminal protocol, and has strong versatility.
