Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0063] Embodiment 1

[0064] To facilitate understanding of this application, Figure 1 The flowchart of a photovoltaic inverter firmware upgrade method provided in the first embodiment of the present invention is shown to describe the contents of the embodiment of the present application in detail.

[0065] See also Figure 1 As shown, Figure 1 A flowchart of a photovoltaic inverter firmware upgrade method provided in the first embodiment of the present invention is shown, wherein the method comprises steps S101 to S103:

[0066] S101: Divide the memory of the photovoltaic inverter into a plurality of storage areas, wherein different firmware data is stored in each storage area.

[0067] Specifically, the memory of the inverter is first divided into multiple independent storage areas, each of which stores specific firmware data. This division method is conducive to organizing and managing firmware data, and can also ensure that different versions or types of firmware data will not interfere with or conflict with each other.

[0068] S102: Acquire an upgrade file of the photovoltaic inverter, and read a field storing an upgrade file type in the upgrade file to obtain an upgrade type of the upgrade file.

[0069] Specifically, when the firmware system starts, the boot program determines whether the PV inverter firmware needs to be upgraded, and determines the target upgrade type (algorithm upgrade and / or data upgrade). Obtain the upgrade file of the target upgrade type for upgrading the PV inverter, which usually contains new firmware data. After obtaining the upgrade file, use professional tools or algorithms to parse it to read the upgrade type, version number, storage area address, MD5 calibration and other fields. The upgrade type may include full upgrade (i.e. replacing the entire firmware), partial upgrade (updating only part of the firmware) or upgrade of specific modules.

[0070] S103: determining a target storage area among the plurality of storage areas according to the upgrade type of the upgrade file, and using the upgrade file to update the firmware data in the target storage area to implement firmware upgrade.

[0071] Specifically, the target storage area is located according to the upgrade type of the upgrade file. The target storage area is the area where the firmware data corresponding to the upgrade file is stored. For example, if the upgrade file is for upgrading the control algorithm of the inverter, then the target storage area is the area where the control algorithm firmware data is stored. The integrity of the upgrade data is judged by a partition verification mechanism (such as CRC or Hash verification) to ensure that the upgrades of different areas do not interfere with each other, and then the data in the upgrade file is used to update the firmware data in the area.

[0072] The present application divides the memory into areas, obtains and parses the upgrade file, and finally updates the firmware data of the target storage area according to the upgrade type. This can achieve partitioned and block upgrades of the firmware, improve upgrade efficiency, and enhance the flexibility and stability of photovoltaic inverter firmware upgrades.

[0073] In an optional implementation scheme, the storage area includes an algorithm area and a data area; the upgrade type includes an algorithm upgrade and a data upgrade; and the step of determining a target storage area from among the plurality of storage areas according to the upgrade type of the upgrade file includes:

[0074] When the upgrade type of the upgrade file is algorithm upgrade, the target storage area is determined to be the algorithm area; when the upgrade type of the upgrade file is data upgrade, the target storage area is determined to be the data area.

[0075] Specifically, the algorithm area is an area in the memory used to store the control algorithm code for the operation of the inverter. Updating the algorithm area can optimize the performance of the controller and thus improve the stability of the system operation. The data area is an area used to store the regulatory parameters, calibration parameters, and equipment information required for the operation of the inverter. Updating these data can optimize the operating parameters of the inverter and improve its adaptability and stability. The data area can also store historical real-time data, historical alarm data, and operation logs. The data area where this data is located can be separately divided into a read-only data area, but this area is not within the scope of the firmware upgrade of this application.

[0076] The purpose of this application is to distinguish the algorithm area from the data area so that the data in different areas can be upgraded separately. If the algorithm upgrade and data upgrade need to be performed at the same time, the files and data in both the algorithm area and the data area are upgraded.

[0077] In an alternative embodiment, see Figure 2 As shown, Figure 2 A flowchart of a method for generating an algorithm upgrade file provided in the first embodiment of the present invention is shown, wherein the method comprises steps S201 to S202:

[0078] S201: For an upgrade file whose upgrade type is algorithm upgrade, an algorithm binary file generator is used to generate an algorithm binary file.

[0079] Specifically, the algorithm binary file generator, that is, the algorithm bin file generator includes a compiler, which uses a GCC compiler or an ARMCC compiler to compile the algorithm source code to generate an original algorithm binary file (usually with a .bin extension), that is, the original algorithm bin file.

[0080] S202: Using a firmware packager to package the algorithm binary file to obtain an upgrade file whose upgrade type is algorithm upgrade.

[0081] Specifically, the firmware packager is used to read the binary file and may add some additional information, such as version number, checksum, configuration file, etc., to finally obtain an algorithm file for upgrading. This file not only contains the original algorithm binary code, but also contains all necessary upgrade information and metadata, and finally obtains the algorithm file for upgrading (upgrade type is an upgrade file for algorithm upgrade).

[0082] In an alternative embodiment, see Figure 3 As shown, Figure 3 A flow chart of a method for generating a data upgrade file provided in the first embodiment of the present invention is shown, wherein the method further comprises steps S301 to S302:

[0083] S301: For an upgrade file whose upgrade type is data upgrade, a data binary file is generated by using a data binary file generator.

[0084] Specifically, a data binary file generator, that is, a data bin file generator (including a parameter selector and a parameter generator) is used to create a data binary file, that is, an original data bin file. This file stores all necessary upgrade information in binary form, ensuring efficient processing and storage of data.

[0085] S302: Using a firmware packager to package the data binary file to obtain an upgrade file whose upgrade type is data upgrade.

[0086] Specifically, it is further processed by the firmware packager. The firmware packager not only packages the data binary file as the core content, but also adds a series of metadata. After the firmware packager completes the packaging process, the data file for the upgrade (the upgrade file with the upgrade type of data upgrade) is finally obtained.

[0087] The data binary file generator and firmware packager can be implemented through shell scripts, host computers, etc. The firmware packager processes the original binary file and appends a 96-byte file header field. The file header contains: record the upgrade target (algorithm or data), version number and storage area address, CRC check, MD5 check and other fields.

[0088] In an optional embodiment, the data binary file generator includes a parameter selector and a parameter generator.

[0089] Specifically, the parameter selector is the first part of the data binary file generator. Its main task is to select the parameters that need to be included in the binary file from a series of available parameters according to specific requirements or conditions. Figure 4 As shown, Figure 4 A schematic diagram of a storage area division provided by the first embodiment of the present invention is shown, wherein the storage area is divided into a user boot area, an algorithm area, a read-write data area (i.e., the data area described in this application), a read-only data area, and a download area. The user boot area includes a secondary boot area, the algorithm area includes a control algorithm area, the read-write data area includes a regulatory parameter area, a calibration parameter area, and a device information area, and the read-only data area includes a historical real-time data area, a historical alarm area, and an operation log area. The read-write data area contains various types of parameters, such as regulatory parameters, calibration parameters, and device information parameters. The parameter selector allows the user or system to select the part that needs to be updated or upgraded from these parameters according to actual needs.

[0090] Once the parameter selector determines the parameter type that needs to be included in the binary file, the parameter generator takes over the next task. The main function of the parameter generator is to perform format matching and conversion according to the type of the selected parameter to generate binary data that meets the device requirements. For different types of parameters (such as regulatory parameters, calibration parameters, or device information parameters), the parameter generator applies different format rules and conversion algorithms to ensure that the generated binary file can be correctly read by the device and burned into the corresponding data partition.

[0091] exist Figure 4 In the scenario shown, the data area is divided into multiple partitions, each of which stores a specific type of parameter data. The parameter generator ensures that the generated binary file matches the format requirements of these partitions so that during the firmware upgrade process, the new parameter data can be accurately written to the corresponding partition.

[0092] See also Figure 5 As shown, Figure 5 A flowchart of a method for generating a data binary file provided by the first embodiment of the present invention is shown, wherein the method of generating a data binary file by using a data binary file generator comprises steps S501 to S502:

[0093] S501: Determine target parameter data from a number of optional parameter data using the parameter selector.

[0094] Specifically, the parameter selector and parameter generator work together in the data binary file generator to complete the entire process from parameter selection to binary data generation. First, the parameter selector selects the parameter type that needs to be included in the binary file from the read-write data area according to user requirements or system instructions.

[0095] S502: Utilize the parameter generator to generate the data binary file according to the target parameter data.

[0096] Specifically, the parameter generator then performs format matching and conversion according to the type of the selected parameter to generate binary data that meets the device requirements. Finally, these binary data are combined into a complete binary file for subsequent firmware upgrade operations.

[0097] In an alternative embodiment, see Figure 6 As shown, Figure 6 A flowchart of a firmware data updating method provided by the first embodiment of the present invention is shown, wherein the storage area includes a download area; the firmware data in the target storage area is updated by using the upgrade file, including steps S601 to S602:

[0098] S601: storing the upgrade file in the download area for verification.

[0099] Specifically, the prepared upgrade file is transferred to the download area of ​​the device. As a temporary storage point, the download area mainly receives and temporarily stores files to be used for firmware updates. Once the upgrade file is successfully stored in the download area, it will be verified immediately.

[0100] S602: If the upgrade file passes the verification process, the original firmware data in the target storage area is deleted, and the upgrade file is written into the target storage area to implement firmware data update.

[0101] Specifically, once the upgrade file passes the verification process, the original firmware data in the target storage area is deleted to ensure that the new firmware data can be written smoothly and occupy the original space to avoid conflicts between the new and old data. Next, the upgrade file in the download area is written to the target storage area. This writing process needs to ensure the accuracy and integrity of the data, and usually includes additional steps such as data format conversion and checksum verification. Once the writing is completed, the device's firmware is successfully updated.

[0102] At this point, some additional initialization steps or restarts may be performed to load new algorithms or data to ensure that the new firmware can run properly and function. The verification processing method includes but is not limited to MD5 verification.

[0103] In an optional embodiment, the method further comprises:

[0104] Use the linker script to specify different storage areas for upgrade files of different upgrade types.

[0105] Specifically, different storage areas are specified for upgrade files of different upgrade types through a link script, including: defining a link script, specifying each storage area in the memory storage of the photovoltaic inverter in the link script; in the link script, allocating a storage address and a storage size to each storage area, and marking different types of upgrade files as belonging to the corresponding storage area defined in the link script.

[0106] Furthermore, the storage addresses of the upgrade files of the algorithm type and the data type are specified through the link script, so as to control the storage of different types of upgrade files into the corresponding target storage area of ​​the device. Figure 7 As shown, Figure 7A schematic diagram of a storage area link script provided by the first embodiment of the present invention is shown, wherein the user boot area (size is 16KB) is loaded into the fixed code segment 0x08000000-0x08004000; the algorithm area (size is 222KB) is loaded into the fixed code segment 0x08004000-0x0803B800; the regulatory parameter area (size is 2KB) in the read-write data area is loaded into the fixed code segment 0x0803B800-0x0803C000; the calibration parameter area (size is 2KB) in the read-write data area is loaded into the fixed code segment 0x0803C000-0x0803C800; the device information area in the read-write data area (size is 2KB) is loaded into the fixed code segment 0x0803C800-0x0803D000; the historical real-time data area in the read-only data area (size is 4KB) is loaded into the fixed code segment 0x0803D000-0x0803E000; the historical alarm area in the read-only data area (size is 4KB) is loaded into the fixed code segment 0x0803E000-0x0803F000; the operation log area in the read-only data area (size is 4KB) is loaded into the fixed code segment 0x0803F000-0x08040000; the download area (size is 256KB) is loaded into the fixed code segment 0x08040000-0x0807FFFF. Generate independent algorithm and data loading image files (*.bin or *.hex) through link scripts, divide the firmware into multiple logical areas (such as control algorithm area, regulatory parameter area, calibration parameter area, device information area, etc.), and load data and algorithms into specific memory addresses respectively to avoid mutual interference.

[0107] When the firmware is upgraded through the photovoltaic inverter firmware upgrade method provided by the present application, an independent checksum mechanism can also be designed for each area to ensure the integrity of the data during the upgrade process. And dynamically load data through a pointer or a configuration structure, where the data loading address is determined by the runtime configuration file. When the algorithm area calls the parameters of the data area, it is directly accessed through the configuration table address to avoid hard-coded coupling. By dynamically loading data through a pointer or a configuration structure and determining the data loading address according to the runtime configuration file, the system can be highly flexible and configurable, avoiding hard-coded coupling, making the code easier to modify and maintain. At the same time, a structured way to manage and access configuration information is also provided, thereby improving the reliability and maintainability of the system.
