[0030] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] First, the basic concepts of professional terms involved in the present invention application are explained as follows:

[0032] See also Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a firmware upgrade method based on a multi-channel battery balancing device, wherein the multi-channel battery balancing device includes a host computer 10 and a plurality of balancing instrument modules 20 electrically connected to the host computer 10, and different balancing instrument modules 20 are associated with different module response identification codes.

[0033] The multi-channel equalizer device is composed of multiple equalizer modules 20, and the host computer 10 and each equalizer module 20 are connected to the same communication bus composed of RS485. Each equalizer module independently controls the equalization control of a battery channel. Each equalizer module has the same independent controller. Each equalizer module is hung on the RS485 bus. The host computer controls the equalization work and firmware upgrade function of each equalizer module through instructions. The host computer reads the compliant firmware upgrade file (referred to as the upgrade file) from the network or USB flash drive. The host computer divides the firmware upgrade file into multiple data packets, and sends them to all equalizer modules in accordance with the rules. After sending each package of upgrade package data, the response status of each module is queried according to the module number, and the corresponding processing method is performed according to the obtained status, that is, the upgrade package data is sent according to a certain time interval.

[0034] The firmware upgrade method based on the multi-channel battery balancing device is applied to the host computer 10. If the host computer 10 sends an upgrade detection instruction to all the equalizer modules 20, so that each equalizer module 20 performs a compliance detection on the basic information of the upgrade file in the upgrade detection instruction, thereby obtaining corresponding compliance detection information; the host computer 10 also sends a first upgrade query instruction to all the equalizer modules 20, so that each equalizer module 20 returns corresponding compliance detection information, and determines the equalizer module to be upgraded according to the compliance detection information; the host computer 10 also sends an upgrade matching instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded detects whether the characteristic information of the upgrade file in the upgrade matching instruction matches the characteristic information of the current upgrade process; the host computer 10 also sends a second upgrade query instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded returns corresponding matching result information, and determines the target equalizer module according to the matching result information; the host computer 10 also completes the firmware upgrade of the target equalizer module when it is detected that the upgrade file sent to the target equalizer module is complete. Therefore, the above method effectively improves the efficiency, security and reliability of firmware upgrades and saves firmware upgrade time and cost by detecting and controlling the firmware upgrade process of all equalizer modules through the host computer 10. At the same time, firmware upgrades can ensure that all devices run on the same version, optimize the collaborative work of each equalizer module, improve the overall performance and reliability of multi-channel battery balancing equipment, and enhance user experience.

[0035] like Figure 1 As shown, in one embodiment, the multi-channel battery balancing device includes a host computer and a plurality of balancing instrument modules electrically connected to the host computer, different balancing instrument modules are associated with different module response identification codes, and the method is applied to the host computer. The firmware upgrade method based on the multi-channel battery balancing device is applied to the host computer of the multi-channel battery balancing device, and the method includes steps S110 to S150.

[0036] Step S110 , sending an upgrade detection instruction to all equalizer modules, so that each equalizer module performs compliance detection on the basic information of the upgrade file in the upgrade detection instruction, thereby obtaining corresponding compliance detection information.

[0037] In this embodiment, the upgrade detection instruction usually includes basic information of the upgrade file. When the upper computer sends the upgrade detection instruction to all equalizer modules, each equalizer module can parse the upgrade detection instruction to obtain the basic information of the upgrade file at this time. By performing compliance detection on the basic information of the upgrade file, the corresponding compliance detection result can be obtained.

[0038] Among them, the upgrade detection instruction can also include a public flag code, which can be 0, and 0 represents the ID set of all equalizer modules. ID (identification) is used to identify the uniqueness of an object, and each object has a unique ID. Usually, different equalizer modules correspond to different instruction module response flag codes, such as, each number in 0-64 can represent the ID of the equalizer module. When the upgrade detection instruction includes a public flag code, it means that the upgrade detection instruction package needs to be sent to all equalizer modules.

[0039] In one embodiment, the upgrade detection instruction includes a public flag code and basic information of the upgrade file, the basic information of the upgrade file includes a module upgrade enable identification code, a firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and the number of upgrade packages, the compliance detection information is the first response flag information, and the step S110 includes the following sub-steps:

[0040] The upgrade detection instruction is sent to all equalizer modules according to the public flag code in the upgrade detection instruction; each equalizer module is controlled to determine whether the module upgrade enable identification code in the upgrade detection instruction is valid; the equalizer module with a valid module upgrade enable identification code is controlled to record the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and number of upgrade packages in the upgrade detection instruction, and perform compliance judgment; the equalizer module with a compliance judgment result is controlled to clear the data in the firmware backup area and the upgrade information area, and designate the corresponding first response mark information as the information code waiting for the upgrade package data; the equalizer module with a non-compliant judgment result is controlled to designate the corresponding first response mark information as the non-compliant information code.

[0041] The upper computer will send the upgrade detection instruction to all equalizer modules according to the public identification code in the upgrade detection instruction, so as to control all equalizer modules to perform compliance detection on the basic information of the upgrade file in the upgrade detection instruction.

[0042] When the equalizer module receives the upgrade detection instruction, it will perform corresponding analysis and determine whether the module upgrade enable identification code is valid. If it is invalid, no processing will be performed. If it is valid, the firmware upgrade file checksum, upgrade file version information, upgrade file size, upgrade package maximum upgrade package size, and the number of upgrade packages will be recorded and compliance will be determined.

[0043] Among them, the module upgrade enable identification code has 8 bytes, a total of 64 bits, each bit represents a corresponding module, and the module upgrade enable identification code can indicate whether the module is included in the upgrade list. If there is no problem with the module upgrade enable identification code, it means that the equalizer module at this time is the module that needs to be upgraded.

[0044] The firmware upgrade file checksum refers to a verification process for the firmware upgrade file to ensure the integrity and correctness of the file. Checksum is a technology used to verify data integrity. It calculates the data of the firmware file to generate a specific value (checksum). Then, during the firmware upgrade process, the equalizer module as the receiver will recalculate this value and compare it with the checksum provided by the sender. If the two match, it means that the firmware file has not been tampered with or damaged during transmission.

[0045] Upgrade file version information usually refers to updates or improvements to the software product, and its version number is adjusted accordingly to reflect these changes.

[0046] Upgrade file size usually refers to the size of the software upgrade package or update file, which is an important indicator to measure the amount of upgrade content and the required storage space.

[0047] In addition, the relationship between the firmware upgrade file, upgrade package and data packet can be summarized as follows: a firmware upgrade file usually contains one or more upgrade packages, and an upgrade package is composed of multiple data packets.

[0048] A firmware upgrade file is a file that contains the firmware update content of a device. Common formats include binary images (.bin), compressed packages (.zip, .tar, .gz, .xz), image files (.img), Intel HEX files (.hex), and Motorola S-record files (.srec, .s19). These files are commonly used in routers, cameras, IoT devices, etc., and contain all the code and data required for the device to operate.

[0049] The upgrade package is a further subdivision of the firmware upgrade file, usually in the form of an update.zip file. The upgrade package is an extension and enhancement of the base package, containing a series of auxiliary tools and services for updating and optimizing the base package.

[0050] Data packets are the specific implementation units of the upgrade package. The firmware file is usually disassembled into 512 bytes, and the end of the file is padded with 0 if it is less than 512 bytes. Each data packet needs to be confirmed by the client before the next data packet is pushed.

[0051] Therefore, it can be seen that the firmware upgrade file is the largest unit, which contains one or more upgrade packages; the upgrade package is composed of multiple data packets, and each data packet contains a part of the firmware update content.

[0052] Specifically, if the module upgrade enable identification code is invalid, no processing is performed. If the module upgrade enable identification code is valid, record the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and number of upgrade packages, and make a compliance judgment. If it is not compliant, designate the first response mark as a non-compliant information code, that is, designate the first response mark as an information code that is not waiting for the upgrade data packet. If it is compliant, the equalizer module clears the data in the firmware backup area and the upgrade information area, and designates the first response mark as the information code waiting for the upgrade data packet, and then waits for the host computer to query the status.

[0053] The firmware backup area is mainly used to store firmware backups so that they can be restored when problems occur during firmware upgrades, while the upgrade information area is used to store firmware upgrade related information, including the storage location of the new firmware and upgrade instructions.

[0054] Step S120: sending a first upgrade query instruction to all equalizer modules, so that each equalizer module returns corresponding compliance detection information, and determines the equalizer module to be upgraded according to the compliance detection information.

[0055] In this embodiment, the host computer sends the first upgrade query instruction to all the equalizer modules in sequence according to the instruction module response flag code corresponding to each equalizer module, thereby controlling each equalizer module to respond to the first upgrade query instruction and return corresponding compliance detection information to the host computer. The host computer can determine the equalizer module to be upgraded based on the returned compliance detection information.

[0056] In one embodiment, the step S120 includes the following sub-steps:

[0057] According to the instruction module response flag codes of all equalizer modules, the first upgrade query command is sent to the corresponding equalizer modules in turn; the equalizer module that has received the first upgrade query command is controlled to return the corresponding first response flag information; if the received first response flag information is an information code waiting for upgrade package data, the equalizer module corresponding to the first response flag information is determined as the equalizer module to be upgraded; if the received first response flag information is an illegal information code, the equalizer module corresponding to the first response flag information is determined as not being the equalizer module to be upgraded.

[0058] The host computer sends the first upgrade query instruction in sequence according to the response identification code of the equalizer module to be upgraded, and the instruction module response identification code can be the ID of the equalizer module. After receiving the first upgrade query instruction, the equalizer module will respond to the response information generated by the upgrade detection instruction, that is, the compliance detection information response to the host computer.

[0059] The host computer removes the module upgrade enable identification code corresponding to the equalizer module that responds to the information code of the waiting upgrade data packet, and makes a corresponding prompt, so as not to include the equalizer module in the upgrade list, ensuring that the equalizer module will not be upgraded. At the same time, when the received first response flag information is the information code of the waiting upgrade package data, the host computer can also determine the equalizer module corresponding to the first response flag information as the equalizer module to be upgraded.

[0060] Step S130: sending an upgrade matching instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded detects whether the characteristic information of the upgrade file in the upgrade matching instruction matches the characteristic information of the current upgrade process.

[0061] In this embodiment, the upper computer can send an upgrade matching instruction to the equalizer module to be upgraded based on the determined equalizer module to be upgraded, thereby controlling the equalizer module to be upgraded to detect whether the characteristic information of the upgrade file in the upgrade matching instruction matches the characteristic information of the current upgrade process, thereby determining whether the equalizer module to be upgraded is suitable for upgrading.

[0062] In one embodiment, the upgrade matching instruction includes a public identification code and characteristic information of the upgrade file, and the characteristic information of the upgrade file includes a module upgrade enable identification code, an upgrade package data number, and upgrade package data; the step S130 includes the following sub-steps:

[0063] According to the public flag code in the upgrade matching instruction, the upgrade matching instruction is sent to all the equalizer modules to be upgraded; each equalizer module to be upgraded is controlled to determine whether the module upgrade enable identification code in the upgrade matching instruction is valid; the equalizer module to be upgraded with the valid module upgrade enable identification code is controlled to determine whether the upgrade package data number in the upgrade matching instruction it receives matches the number of the data packet it currently needs; if they match, the equalizer module to be upgraded is controlled to write the upgrade package data in the upgrade matching instruction into the firmware backup area, and designate the corresponding response mark information as the information code waiting for the upgrade package data.

[0064] The host computer can send the upgrade matching instruction to all equalizer modules to be upgraded according to the public identification code in the upgrade matching instruction. For example, if the instruction module response identification code is 0, the equalizer module does not respond autonomously.

[0065] The equalizer module receives the upgrade matching instruction sent by the host computer and parses it. First, it determines whether the module upgrade enable identification code is valid. If it is invalid, no processing is performed. If it is valid, it determines whether the upgrade package data number in the characteristic information of the currently issued upgrade file matches the number of the data packet required in the current upgrade process. If it does not match, the information of the response failure of the data packet mismatch is recorded. If it matches, the upgrade package data is written to the corresponding position in the firmware backup area, and the count of the upgrade package data is increased by one, and the response mark is designated as the information code waiting for the upgrade data packet. Finally, wait for the host computer to query the status.

[0066] Step S140: sending a second upgrade query instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded returns corresponding matching result information, and determines the target equalizer module according to the matching result information.

[0067] In this embodiment, the host computer can send the second upgrade query instruction to each equalizer module to be upgraded in sequence according to the instruction module response flag code of the equalizer module to be upgraded, so as to control the equalizer module to be upgraded to return the corresponding matching result information, and determine the target equalizer module according to the matching result information. If the matching result information is not matched, the equalizer module to be upgraded will no longer be upgraded. If it is matched, the next step of operation will be performed.

[0068] In one embodiment, the matching information result is second response flag information, and step S140 includes the following sub-steps:

[0069] According to the instruction module response flag codes of all equalizer modules to be upgraded, the second upgrade query command is sent to the corresponding equalizer modules in turn; the equalizer module that has received the second upgrade query command is controlled to return the corresponding second response flag information; if the received second response flag information is an information code waiting for upgrade package data, the equalizer module corresponding to the second response flag information is determined as the target equalizer module.

[0070] Among them, the host computer sends the second upgrade query instruction to the module in sequence according to the instruction module response identification code, and this instruction module response identification code is the module ID. The equalizer module receives the second upgrade query instruction and responds to the host computer with the second response information in response to the upgrade matching instruction. The host computer removes the module upgrade enable identification code corresponding to the equalizer module whose response is not the information code of waiting for the upgrade data packet, and records the ID of the module that failed to respond. If the received second response flag information is the information code of waiting for the upgrade package data, the equalizer module corresponding to the second response flag information is determined as the target equalizer module.

[0071] Step S150: If it is detected that the upgrade file sent to the target equalizer module is complete, the firmware upgrade of the target equalizer module is completed.

[0072] In this embodiment, if the host computer detects that the upgrade file sent to the target equalizer module is complete, the firmware upgrade of the target equalizer module is completed.

[0073] In one embodiment, step 150 may further include the following steps:

[0074] Determine whether the upgrade package data sent to all target equalizer modules is the last package data in the upgrade file; if so, control each target equalizer module to calculate the data checksum of all upgrade package data written to the firmware backup area; determine whether the calculated data checksum matches the firmware upgrade file checksum; if the match is successful, write the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and number of upgrade packages included in the upgrade detection instruction into the upgrade information area to complete the firmware upgrade of the target equalizer module.

[0075] Among them, after the host computer determines the target equalizer module, it determines whether the upgrade package data sent to all target equalizer modules is the last package data in the upgrade file. If not, return to continue to execute step S130 and step S140. If so, control each target equalizer module to calculate the data checksum of all upgrade package data written to the firmware backup area, and determine whether the calculated data checksum matches the firmware upgrade file checksum. If the match is successful, the firmware upgrade file checksum, upgrade file version information, upgrade file size, upgrade package maximum upgrade package size, and number of upgrade packages included in the upgrade detection instruction are written into the upgrade information area to complete the firmware upgrade of the target equalizer module. If the match is unsuccessful, it means that the upgrade failed. If the upgrade fails, the host computer will restart the upgrade process at this time.

[0076] like Figure 3 As shown, in another embodiment of the invention, the present invention further includes the following steps:

[0077] S1, each equalizer module receives the upgrade instruction 1 (upgrade detection instruction) to match the upgrade information, and after determining that the match is successful, the equalizer module is ready for upgrading.

[0078] S2, the host computer sends upgrade instructions 2 (first upgrade query instructions) to the equalizer modules in sequence according to the equalizer module ID, so that the equalizer module returns the result to the host computer.

[0079] S3, the host computer receives the returned result and analyzes it.

[0080] S4, the host computer sends an upgrade instruction 3 (upgrade matching instruction) to the equalizer module, so that the equalizer module receives the upgrade data packet and saves it, and waits for the host computer to obtain the status.

[0081] S5, the host computer sends an upgrade instruction 4 (upgrade matching instruction) to the equalizer module, so that the equalizer module responds with corresponding status information;

[0082] S6, when the host computer receives the status information of the response in S5, it determines whether all the upgrade package data has been sent. If so, the upgrade is successfully completed. Otherwise, it returns to S4.

[0083] It can be seen from this that by detecting and controlling the firmware upgrade process of all equalizer modules by the upper computer 10, automatic upgrade of multiple equalizer modules in a multi-channel equalizer device can be achieved, that is, the firmware upgrade can ensure that all equalizer modules of the device run on the same version, thereby improving the overall performance and reliability of the system.

[0084] In summary, the method of the above embodiment can effectively improve the efficiency, security and reliability of firmware upgrades, save time and cost of firmware upgrades. At the same time, firmware upgrades can ensure that all devices run on the same version, optimize the collaborative work of each equalizer module, improve the overall performance and reliability of multi-channel battery balancing equipment, and enhance user experience.

[0085] The embodiment of the present invention also provides a firmware upgrade device based on a multi-channel battery balancing device, which can be configured in a host computer of the multi-channel battery balancing device, and is used to execute any embodiment of the firmware upgrade method based on the multi-channel battery balancing device. Specifically, please refer to Figure 4 , Figure 4 A schematic block diagram of a firmware upgrade device based on a multi-channel battery balancing device provided by an embodiment of the present invention.

[0086] like Figure 4 As shown, the firmware upgrade device 100 based on the multi-channel battery balancing device includes an upgrade detection unit 110 , a first upgrade query unit 120 , an upgrade matching unit 130 , a second upgrade query unit 140 and an upgrade processing unit 150 .

[0087] The upgrade detection unit 110 is used to send an upgrade detection instruction to all equalizer modules, so that each equalizer module performs a compliance detection on the basic information of the upgrade file in the upgrade detection instruction, thereby obtaining corresponding compliance detection information.

[0088] In this embodiment, the upgrade detection instruction usually includes basic information of the upgrade file. When the upper computer sends the upgrade detection instruction to all equalizer modules, each equalizer module can parse the upgrade detection instruction to obtain the basic information of the upgrade file at this time. By performing compliance detection on the basic information of the upgrade file, the corresponding compliance detection result can be obtained.

[0089] Among them, the upgrade detection instruction can also include a public flag code, which can be 0, and 0 represents the ID set of all equalizer modules. ID (identification) is used to identify the uniqueness of an object, and each object has a unique ID. Usually, different equalizer modules correspond to different instruction module response flag codes, such as, each number in 0-64 can represent the ID of the equalizer module. When the upgrade detection instruction includes a public flag code, it means that the upgrade detection instruction package needs to be sent to all equalizer modules.

[0090] In one embodiment, the upgrade detection instruction includes a public flag code and basic information of the upgrade file, the basic information of the upgrade file includes a module upgrade enable identification code, a firmware upgrade file checksum, an upgrade file version information, an upgrade file size, a maximum upgrade package size, and the number of upgrade packages, the compliance detection information is the first response flag information, and the upgrade detection unit 110 is further used to perform the following steps:

[0091] The upgrade detection instruction is sent to all equalizer modules according to the public flag code in the upgrade detection instruction; each equalizer module is controlled to determine whether the module upgrade enable identification code in the upgrade detection instruction is valid; the equalizer module with the valid module upgrade enable identification code is controlled to record the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, number of upgrade packages in the upgrade detection instruction, and perform compliance judgment; the equalizer module with the judgment result of compliance is controlled to clear the data in the firmware backup area and the upgrade information area, and designate the corresponding first response mark information as the information code waiting for the upgrade package data; the equalizer module with the judgment result of non-compliance is controlled to designate the corresponding first response mark information as the non-compliant information code.

[0092] The upper computer will send the upgrade detection instruction to all equalizer modules according to the public identification code in the upgrade detection instruction, so as to control all equalizer modules to perform compliance detection on the basic information of the upgrade file in the upgrade detection instruction.

[0093] When the equalizer module receives the upgrade detection instruction, it will perform corresponding analysis and determine whether the module upgrade enable identification code is valid. If it is invalid, no processing will be performed. If it is valid, the firmware upgrade file checksum, upgrade file version information, upgrade file size, upgrade package maximum upgrade package size, and the number of upgrade packages will be recorded and compliance will be determined.

[0094] Among them, the module upgrade enable identification code has 8 bytes, a total of 64 bits, each bit represents a corresponding module, and the module upgrade enable identification code can indicate whether the module is included in the upgrade list. If there is no problem with the module upgrade enable identification code, it means that the equalizer module at this time is the module that needs to be upgraded.

[0095] The firmware upgrade file checksum refers to a verification process for the firmware upgrade file to ensure the integrity and correctness of the file. Checksum is a technology used to verify data integrity. It calculates the data of the firmware file to generate a specific value (checksum). Then, during the firmware upgrade process, the equalizer module as the receiver will recalculate this value and compare it with the checksum provided by the sender. If the two match, it means that the firmware file has not been tampered with or damaged during transmission.

[0096] Upgrade file version information usually refers to updates or improvements to the software product, and its version number is adjusted accordingly to reflect these changes.

[0097] Upgrade file size usually refers to the size of the software upgrade package or update file, which is an important indicator to measure the amount of upgrade content and the required storage space.

[0098] In addition, the relationship between the firmware upgrade file, upgrade package and data packet can be summarized as follows: a firmware upgrade file usually contains one or more upgrade packages, and an upgrade package is composed of multiple data packets.

[0099] A firmware upgrade file is a file that contains the firmware update content of a device. Common formats include binary images (.bin), compressed packages (.zip, .tar, .gz, .xz), image files (.img), Intel HEX files (.hex), and Motorola S-record files (.srec, .s19). These files are commonly used in routers, cameras, IoT devices, etc., and contain all the code and data required for the device to operate.

[0100] The upgrade package is a further subdivision of the firmware upgrade file, usually in the form of an update.zip file. The upgrade package is an extension and enhancement of the base package, containing a series of auxiliary tools and services for updating and optimizing the base package.

[0101] Data packets are the specific implementation units of the upgrade package. The firmware file is usually disassembled into 512 bytes, and the end of the file is padded with 0 if it is less than 512 bytes. Each data packet needs to be confirmed by the client before the next data packet is pushed.

[0102] Therefore, it can be seen that the firmware upgrade file is the largest unit, which contains one or more upgrade packages; the upgrade package is composed of multiple data packets, and each data packet contains a part of the firmware update content.

[0103] Specifically, if the module upgrade enable identification code is invalid, no processing is performed. If the module upgrade enable identification code is valid, record the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and number of upgrade packages, and make a compliance judgment. If it is not compliant, designate the first response mark as a non-compliant information code, that is, designate the first response mark as an information code that is not waiting for the upgrade data packet. If it is compliant, the equalizer module clears the data in the firmware backup area and the upgrade information area, and designates the first response mark as the information code waiting for the upgrade data packet, and then waits for the host computer to query the status.

[0104] The firmware backup area is mainly used to store firmware backups so that they can be restored when problems occur during firmware upgrades, while the upgrade information area is used to store firmware upgrade related information, including the storage location of the new firmware and upgrade instructions.

[0105] The first upgrade query unit 120 is used to send a first upgrade query instruction to all equalizer modules, so that each equalizer module returns corresponding compliance detection information, and determines the equalizer module to be upgraded according to the compliance detection information.

[0106] In this embodiment, the host computer sends the first upgrade query instruction to all the equalizer modules in sequence according to the instruction module response flag code corresponding to each equalizer module, thereby controlling each equalizer module to respond to the first upgrade query instruction and return corresponding compliance detection information to the host computer. The host computer can determine the equalizer module to be upgraded based on the returned compliance detection information.

[0107] In one embodiment, the first upgrade query unit 120 is further configured to perform the following sub-steps:

[0108] According to the instruction module response flag codes of all equalizer modules, the first upgrade query command is sent to the corresponding equalizer modules in turn; the equalizer module that has received the first upgrade query command is controlled to return the corresponding first response flag information; if the received first response flag information is an information code waiting for upgrade package data, the equalizer module corresponding to the first response flag information is determined as the equalizer module to be upgraded; if the received first response flag information is an illegal information code, the equalizer module corresponding to the first response flag information is determined as not being the equalizer module to be upgraded.

[0109] The host computer sends the first upgrade query instruction in sequence according to the response identification code of the equalizer module to be upgraded, and the instruction module response identification code can be the ID of the equalizer module. After receiving the first upgrade query instruction, the equalizer module will respond to the response information generated by the upgrade detection instruction, that is, the compliance detection information response to the host computer.

[0110] The host computer removes the module upgrade enable identification code corresponding to the equalizer module that responds to the information code of the waiting upgrade data packet, and makes a corresponding prompt, so as not to include the equalizer module in the upgrade list, ensuring that the equalizer module will not be upgraded. At the same time, when the received first response flag information is the information code of the waiting upgrade package data, the host computer can also determine the equalizer module corresponding to the first response flag information as the equalizer module to be upgraded.

[0111] The upgrade matching unit 130 is used to send an upgrade matching instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded detects whether the characteristic information of the upgrade file in the upgrade matching instruction matches the characteristic information of the current upgrade process.

[0112] In this embodiment, the upper computer can send an upgrade matching instruction to the equalizer module to be upgraded based on the determined equalizer module to be upgraded, thereby controlling the equalizer module to be upgraded to detect whether the characteristic information of the upgrade file in the upgrade matching instruction matches the characteristic information of the current upgrade process, thereby determining whether the equalizer module to be upgraded is suitable for upgrading.

[0113] In one embodiment, the upgrade matching instruction includes a public identification code and characteristic information of the upgrade file, and the characteristic information of the upgrade file includes a module upgrade enable identification code, an upgrade package data number, and upgrade package data; the upgrade matching unit 130 is further used to perform the following sub-steps:

[0114] According to the public flag code in the upgrade matching instruction, the upgrade matching instruction is sent to all the equalizer modules to be upgraded; each equalizer module to be upgraded is controlled to determine whether the module upgrade enable identification code in the upgrade matching instruction is valid; the equalizer module to be upgraded with the valid module upgrade enable identification code is controlled to determine whether the upgrade package data number in the upgrade matching instruction it receives matches the number of the data packet it currently needs; if they match, the equalizer module to be upgraded is controlled to write the upgrade package data in the upgrade matching instruction into the firmware backup area, and designate the corresponding response mark information as the information code waiting for the upgrade package data.

[0115] The host computer can send the upgrade matching instruction to all equalizer modules to be upgraded according to the public identification code in the upgrade matching instruction. For example, if the instruction module response identification code is 0, the equalizer module does not respond autonomously.

[0116] The equalizer module receives the upgrade matching instruction sent by the host computer and parses it. First, it determines whether the module upgrade enable identification code is valid. If it is invalid, no processing is performed. If it is valid, it determines whether the upgrade package data number in the characteristic information of the currently issued upgrade file matches the number of the data packet required in the current upgrade process. If it does not match, the information of the response failure of the data packet mismatch is recorded. If it matches, the upgrade package data is written to the corresponding position in the firmware backup area, and the count of the upgrade package data is increased by one, and the response mark is designated as the information code waiting for the upgrade data packet. Finally, wait for the host computer to query the status.

[0117] The second upgrade query unit 140 is used to send a second upgrade query instruction to the equalizer module to be upgraded, so that the equalizer module to be upgraded returns corresponding matching result information, and determines the target equalizer module according to the matching result information.

[0118] In this embodiment, the host computer can send the second upgrade query instruction to each equalizer module to be upgraded in sequence according to the instruction module response flag code of the equalizer module to be upgraded, so as to control the equalizer module to be upgraded to return the corresponding matching result information, and determine the target equalizer module according to the matching result information. If the matching result information is not matched, the equalizer module to be upgraded will no longer be upgraded. If it is matched, the next step of operation will be performed.

[0119] In one embodiment, the matching information result is second response flag information, and the second upgrade query unit 140 is further configured to perform the following sub-steps:

[0120] According to the instruction module response flag codes of all equalizer modules to be upgraded, the second upgrade query command is sent to the corresponding equalizer modules in turn; the equalizer module that has received the second upgrade query command is controlled to return the corresponding second response flag information; if the received second response flag information is an information code waiting for upgrade package data, the equalizer module corresponding to the second response flag information is determined as the target equalizer module.

[0121] Among them, the host computer sends the second upgrade query instruction to the module in sequence according to the instruction module response identification code, and this instruction module response identification code is the module ID. The equalizer module receives the second upgrade query instruction and responds to the host computer with the second response information in response to the upgrade matching instruction. The host computer removes the module upgrade enable identification code corresponding to the equalizer module whose response is not the information code of waiting for the upgrade data packet, and records the ID of the module that failed to respond. If the received second response flag information is the information code of waiting for the upgrade package data, the equalizer module corresponding to the second response flag information is determined as the target equalizer module.

[0122] The upgrade processing unit 150 is used to complete the firmware upgrade of the target equalizer module if it is detected that the upgrade file sent to the target equalizer module is complete.

[0123] In this embodiment, if the host computer detects that the upgrade file sent to the target equalizer module is complete, the firmware upgrade of the target equalizer module is completed.

[0124] In one embodiment, the upgrade processing unit 150 may also be used to perform the following steps:

[0125] Determine whether the upgrade package data sent to all target equalizer modules is the last package data in the upgrade file; if so, control each target equalizer module to calculate the data checksum of all upgrade package data written to the firmware backup area; determine whether the calculated data checksum matches the firmware upgrade file checksum; if the match is successful, write the firmware upgrade file checksum, upgrade file version information, upgrade file size, maximum upgrade package size, and number of upgrade packages included in the upgrade detection instruction into the upgrade information area to complete the firmware upgrade of the target equalizer module.

[0126] Among them, after the upper computer determines the target equalizer module, it determines whether the upgrade package data sent to all target equalizer modules is the last package data in the upgrade file. If not, return to the upgrade matching unit 130 and the second upgrade query unit 140 to execute relevant steps. If so, control each target equalizer module to calculate the data checksum of all upgrade package data written to the firmware backup area, and determine whether the calculated data checksum matches the firmware upgrade file checksum. If the match is successful, the firmware upgrade file checksum, upgrade file version information, upgrade file size, upgrade package maximum upgrade package size, and number of upgrade packages included in the upgrade detection instruction are written into the upgrade information area to complete the firmware upgrade of the target equalizer module. If the match is unsuccessful, it means that the upgrade failed. If the upgrade fails, the upper computer will restart the upgrade process at this time.
