[0025] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0026] In order to solve the problem in the related art that there are a large number of inverters in the inverter system and that the traditional method of upgrading each inverter one by one takes a long time, an embodiment of the present invention provides a batch upgrade method for the inverter system.

[0027] Figure 1 is a flow chart of a batch upgrade method of an inverter system according to an embodiment of the present invention, such as Figure 1 As shown, the batch upgrade method of the inverter system provided by the embodiment of the invention comprises the following steps: Step S101, splitting the inverter upgrade package to obtain multiple partial files; Step S102, broadcasting multiple partial files to the inverters that need to be upgraded in batches by broadcasting, wherein after receiving the multiple partial files, the inverter detects and assembles them into an upgrade package, and feeds back the partial files with abnormal detection through a reply message; Step S103, receiving a reply message from the inverter for the missing part of the file; Step S104, in response to the reply message, the missing part of the file is resent to the corresponding inverter, wherein the inverter writes the missing part of the file into the upgrade package and uses the upgrade package for upgrading.

[0028] The batch upgrade method for the above-mentioned inverter system provided by the embodiment created by the present invention divides the upgrade package with a larger data volume into partial files with smaller data volume, transmits the partial files in batches by broadcasting, and detects the reply message of the partial files through the inverter to reissue the missing partial files, and sends the upgrade packages to the inverter in batches, thereby batch issuing the upgrade packages to multiple inverters in the inverter system, so that the inverters that need to be upgraded can be upgraded in parallel, thereby greatly shortening the upgrade time of multiple inverters in the inverter system and greatly reducing the time-consuming technical effect of upgrading multiple inverters of the inverter system.

[0029] The execution subject of the above steps may be an energy gateway of the inverter system, for example, ECC (Energy Control Center) and ECC_PLC (Power Line Carrier). The above inverter system may include a cloud server, an energy gateway, and an inverter.

[0030] The cloud server can store data in the form of cloud services, including upgrade packages, upgrade records, historical data, etc. The energy gateway can be used as the gateway of the inverter, set between the inverter and the cloud server, can run the control program, and can also serve as a communication medium between the cloud server and the inverter.

[0031] The above upgrade package can be stored in the cloud server, or edited by the remote terminal and uploaded to the cloud server. For the energy gateway, when upgrading, the cloud server can initiate an upgrade instruction and send the upgrade instruction to the energy gateway, carrying relevant upgrade information.

[0032] After obtaining the upgrade package, split the upgrade package into multiple partial files. The data size of the partial files must not exceed the maximum data size sent in a single broadcast batch. If it exceeds, a single broadcast batch may not be able to send a partial file. In other words, a single broadcast batch must send at least one partial file.

[0033] Then, multiple partial files can be broadcasted in batches to the inverters that need to be upgraded. It should be noted that the inverters that need to be upgraded can be described in the upgrade package, or described through the supporting files of the upgrade package, which can be the same as the way to obtain the upgrade package, or can be carried through the upgrade instruction and sent to the energy gateway.

[0034] After receiving multiple partial files, the inverter can perform tests. For example, completion check, safety check, bitmap check, etc. After passing the test, they can be assembled into an upgrade package, and the partial files with abnormal detection can be fed back through reply messages. The above detection abnormalities correspond to the above detection methods, that is, the completion check fails, the safety check fails, and the bitmap detection is missing.

[0035] The abnormal part of the files can be fed back to the energy gateway by replying messages. The energy gateway will resend the abnormal part of the files for a specific inverter according to the different situations of each inverter. This resending method can be through PLC communication, or through the existing one-to-one or one-to-many communication methods of the inverter such as broadcasting.

[0036] After receiving the reply message of the inverter for the missing partial files, the energy gateway responds to the reply message and resends the missing partial files to the corresponding inverter. After receiving the missing partial files resent by the energy gateway, the inverter writes the missing partial files into the upgrade package, improves the upgrade package, and uses the improved upgrade package for upgrading.

[0037] As an optional embodiment, before splitting the inverter upgrade package to obtain multiple partial files, the method also includes: downloading and parsing upgrade information from a cloud server, wherein the upgrade information includes device information that needs to be upgraded and upgrade package information for pulling the upgrade package; pulling the upgrade package from the cloud server according to the upgrade package information; and during the process of pulling the upgrade package, feeding back the download status of the upgrade package to the cloud server, wherein the download status includes whether the download has started, whether the download has been completed, and the degree of download completion.

[0038] Since the upgrade package is stored in the cloud server, before the upgrade package of the inverter is divided into multiple partial files, the upgrade package needs to be obtained from the cloud server first.

[0039] Figure 2 : is a timing diagram of the upgrade package downloading of the embodiment created by the present invention, such as Figure 2 As shown, the cloud server sends the upgrade information to the energy gateway ECC through the MQTT communication protocol. The upgrade information includes the device information that needs to be upgraded, such as the upgrade device SN table, and the upgrade information, such as the upgrade file URL.

[0040] It should be noted that Figures 2 to 6 In the above description, both ECC and ECC_PLC belong to the energy gateway, and can be understood as different parts of the energy gateway. In other embodiments, both ECC and ECC_PLC can be used as energy gateways alone.

[0041] After the energy gateway ECC downloads and parses the upgrade information from the cloud server, it pulls the upgrade package from the cloud server according to the upgrade package information. Figure 2 In the process, HTTP (Hyper Text Transfer Protocol) is used to request the cloud server to pull the upgrade package. The cloud server responds to the HTTP request and sends the upgrade package back.

[0042] After receiving the data of the upgrade package, ECC reports the download status of the upgrade package through the MQTT (Message Queuing Telemetry Transport) protocol. The download status includes whether the download has started, whether the download has been completed, and the degree of download completion. Figure 2The word "loop" means "cycle". This is because the download of the upgrade package is a cyclic process of multiple rounds. The cycle ends when the download is completed. Figures 3 to 6 are the same in all.

[0043] As an optional embodiment, after pulling the upgrade package from the cloud server according to the upgrade package information, the method also includes: verifying the upgrade package; if the verification fails, providing feedback to the cloud server, re-downloading the upgrade information, and pulling the upgrade package; if the verification passes, notifying the corresponding device to upgrade according to the device information.

[0044] like Figure 2 As shown in the figure, after ECC downloads the upgrade package from the cloud server, it verifies the integrity and legality of the downloaded upgrade package file to ensure the accuracy and security of the upgrade package, which guarantees the subsequent batch distribution.

[0045] As an optional embodiment, upgrading the device corresponding to the device information notification includes: sending a start upgrade instruction to the inverter corresponding to the device information, wherein the inverter initializes the device after receiving the start upgrade instruction, and after the initialization is completed, feeds back a notification message that it is ready to receive the upgrade package; based on the inverter that receives the notification message, determining the initialization process of multiple inverters of the device information; and feeding back the initialization process to the cloud server.

[0046] Figure 3 : is a timing diagram of the inverter initialization of the embodiment of the present invention, such as Figure 3 As shown, when notifying the corresponding device to initialize in preparation for upgrading, the ECC sends a start upgrading instruction to the inverter corresponding to the device information. Figure 3 It can be forwarded through ECC_PLC.

[0047] After receiving the upgrade start command, the inverter initializes the device and sends a notification message that it is ready to receive the upgrade package after the initialization is completed. Figure 3 The notification message is forwarded to ECC through ECC_PLC. When ECC receives the notification message of a certain inverter, it can be clear that the initialization of the inverter is completed.

[0048] Since there are probably multiple inverters that need to be upgraded, the time for receiving different inverters is different. ECC can determine the initialization process of multiple inverters in device information based on the inverters that received the notification message. Initialization process (%) = number of inverters that received the notification message / total number of inverters that need to be upgraded.

[0049] After the initialization calculation is completed, ECC can feedback the initialization process to the cloud server through the MQTT protocol.

[0050] As an optional embodiment, multiple partial files are broadcasted in batches to the inverter that needs to be upgraded, including: broadcasting partial files to the inverter that needs to be upgraded in batches at a preset frequency, wherein an integer number of partial files are broadcast in each batch, and after the inverter receives the partial files, an abnormality check is performed, and if the check passes, the partial files are assembled into an upgrade package, and if the check fails, the abnormal partial files are replied; after the partial files of the upgrade package are broadcast, the step of receiving the inverter's reply message for the missing partial files is executed.

[0051] Figure 4 : is a timing diagram of the broadcast transmission upgrade package of the embodiment created by the present invention, such as Figure 4 As shown, ECC broadcasts partial files to the inverters that need to be upgraded in batches according to a preset frequency. An integer number of partial files are broadcast in each batch to avoid further segmentation of the partial files during transmission, thereby ensuring the accuracy of partial file transmission.

[0052] Figure 3 After receiving the partial files, the inverter directly writes the upgrade package, which means that the partial files are safe and complete by default. In other embodiments, the inverter can perform an abnormality check after receiving the partial files. If the check passes, the partial files are assembled into an upgrade package. If the check fails, the abnormal partial files are replied to ensure the integrity and accuracy of the partial files and the upgrade package.

[0053] The above-mentioned abnormality check can be one of the above-mentioned completion check, security check, bitmap detection, etc. After the test is passed, it can be assembled into an upgrade package, and the part of the file with the detection abnormality can be fed back through a reply message. The above-mentioned detection abnormality corresponds to the above-mentioned detection method, that is, the completion check fails, the security check fails, and the bitmap detection is missing.

[0054] After ECC broadcasts some files of the upgrade package in each batch, it can report the broadcast progress of the upgrade package to the cloud server through the MQTT protocol. The broadcast progress is actually the ratio of the distributed partial files to the total partial files. After the partial files of the upgrade package are distributed as a whole through cyclic broadcast, the step of receiving the inverter's reply message for the missing partial files is executed.

[0055] As an optional embodiment, after broadcasting partial files of the upgrade package and before executing the step of receiving the inverter's reply message for the missing partial files, the step includes: querying a bitmap through multiple partial files of the upgrade package to obtain bitmap information of the multiple partial files, wherein the bitmap information includes information for characterizing whether the multiple partial files are missing; sending the bitmap information to the inverter that receives the upgrade package, wherein after receiving the bitmap information, the inverter processes the bitmap information according to the received partial files to obtain a reply bitmap message, wherein the reply bitmap message characterizes whether the partial files received by the inverter are missing.

[0056] Figure 5 It is a timing diagram of querying the bitmap re-issuing the upgrade package according to the embodiment of the present invention, such as Figure 5 As shown, when verifying some files based on bitmap detection, the inverter needs to first obtain accurate bitmap information of some files of the upgrade package, and use the bitmap information to perform abnormality detection.

[0057] ECC queries the bitmap to obtain bitmap information of the multiple partial files based on the multiple partial files of the upgrade package. The bitmap information records all the partial files of the upgrade package in a bitmap manner. By searching based on the bitmap information, it can be determined whether there is a missing file and which partial file is missing.

[0058] ECC sends the bitmap information to the inverter that receives the upgrade package. After receiving the bitmap information, the inverter processes the bitmap information according to the received partial files to obtain a reply bitmap message. The reply bitmap message indicates whether the partial files received by the inverter are missing.

[0059] It should be noted that the above Figure 5 In the process, the contents sent by ECC to the inverter are all forwarded by ECC_PLC. The information returned by the inverter to ECC is also forwarded by ECC_PLC.

[0060] As an optional embodiment, receiving a reply message from the inverter for missing partial files includes: receiving a reply bitmap message, determining whether the corresponding inverter is missing partial files and identifying the missing partial files if the partial files are missing according to the reply bitmap message; responding to the reply message and resending the missing partial files to the corresponding inverter includes: when determining that the partial files are missing, obtaining the corresponding partial files and generating a missing package according to the missing partial file identifier; sending the missing package to the corresponding inverter, wherein after receiving the missing package, the inverter writes the corresponding partial files into an upgrade package and feeds back the reception completion information of the upgrade package; determining the sending progress of the missing package according to the inverter that receives the reception completion information and all inverters that receive the upgrade package, and feeding back the progress to the cloud server.

[0061] like Figure 5As shown, after determining the reply bitmap message of each inverter, the missing packet is resent to the corresponding inverter. Specifically, after receiving the reply bitmap message of the inverter, the ECC can determine whether the corresponding inverter is missing some files according to the reply bitmap message, and which files are missing if some files are missing.

[0062] When determining that a partial file is missing, the ECC obtains the corresponding partial file according to the missing partial file identifier, generates a missing packet, and sends the missing packet to the corresponding inverter.

[0063] After the inverter receives the missing package, it writes the corresponding part of the file into the upgrade package after abnormal detection, and feedbacks the reception completion information of the upgrade package. After the ECC receives the reception completion information of the inverter, it can determine that the inverter has completed the reception of the upgrade package.

[0064] Similarly, since the number of inverters that ECC is responsible for upgrading is usually multiple, the sending progress of the missing packets can be determined based on the inverters that have received the reception completion information and all the inverters that have received the upgrade packages. The sending progress is the ratio of the number of inverters that have received the reception completion information to the number of inverters that need to be upgraded.

[0065] like Figure 5 As shown in the figure, after the sending progress calculation is completed, ECC feeds back the sending progress to the cloud server cloud through the MQTT protocol so as to provide real-time feedback to the user.

[0066] As an optional embodiment, after responding to the reply message and resending the missing part of the files to the corresponding inverter, the method also includes: sending an upgrade result query request to the upgraded inverter, wherein after the inverter receives the missing part of the files, it completes the reception of the upgrade package, and upgrades according to the upgrade package. After the upgrade is completed, it responds to the upgrade result query request and feeds back the upgrade result; receives the upgrade result returned in response to the upgrade result query request; determines the upgrade process based on the inverter for which the upgrade result is successful and the inverter that needs to be upgraded, and feeds back to the cloud server.

[0067] Figure 6 It is a timing diagram of the query upgrade result of the embodiment created by the present invention, such as Figure 6 As shown, the inverter will be upgraded according to the upgrade package, and ECC can send an upgrade result query request to the upgraded inverter. Figure 6 Forwarding is performed through ECC_PLC.

[0068] After the inverter receives the query request, it may not be upgraded completely. You can wait for the inverter to complete the upgrade according to the upgrade package, and then respond to the upgrade result query request and feedback the upgrade result. Figure 6The upgrade result may include upgrade success or upgrade failure.

[0069] The ECC receives the upgrade result returned in response to the upgrade result query request. If the upgrade is successful, it determines that the corresponding inverter has been upgraded. If it fails, the upgrade package can be re-issued to the inverter separately for upgrading until the upgrade is successful or the number of cycles reaches the preset number.

[0070] Similarly, since the number of inverters that ECC is responsible for upgrading is usually multiple, ECC determines the upgrade progress based on the inverters that have received successful upgrade results and the inverters that need to be upgraded. The upgrade progress is the ratio of the number of inverters that have received successful upgrade results to the total number of inverters that need to be upgraded. Figure 6 As shown, ECC feeds back the upgrade process to the cloud server through the MQTT protocol so as to provide real-time feedback to users.

[0071] Based on the batch upgrade method of the inverter system provided by the embodiment of the invention, the embodiment of the invention further provides a batch upgrade device of the inverter system, which is applied to batch upgrade of multiple inverters of the inverter system. The batch upgrade device of the inverter system includes: A segmentation module is used to segment the upgrade package of the inverter to obtain multiple partial files; a broadcast module is connected to the above segmentation module and is used to broadcast the multiple partial files in batches to the inverter that needs to be upgraded, wherein the inverter detects and assembles the multiple partial files into an upgrade package after receiving the multiple partial files, and feeds back the partial files with abnormal detection through a reply message; a receiving module is connected to the above broadcast module and is used to receive the inverter's reply message for the missing partial files; a resending module is connected to the above receiving module and is used to respond to the reply message and resend the missing partial files to the corresponding inverter, wherein the inverter writes the missing partial files into the upgrade package and uses the upgrade package for upgrading.

[0072] The batch upgrade device for the above-mentioned inverter system provided by the embodiment created by the present invention divides the upgrade package with a larger data volume into partial files with smaller data volume, transmits the partial files in batches by broadcasting, and detects the reply message of the partial files through the inverter, reissues the missing partial files, and sends the upgrade packages to the inverter in batches, thereby batch issuing the upgrade packages to multiple inverters in the inverter system, so that the inverters that need to be upgraded can be upgraded in parallel, thereby greatly shortening the upgrade time of multiple inverters in the inverter system, and greatly reducing the time-consuming technical effect of upgrading multiple inverters of the inverter system.
