[0002] When upgrading the firmware of devices such as inverters, a mobile Wifi device is usually used to send a newer version of the firmware to the inverter. After the user terminal sends an upgrade instruction to the server, the server compares the server's firmware version with the device's firmware version based on the upgrade instruction. If the server has a newer version of the firmware, the newer version of the firmware is transmitted to the mobile Wifi device through the mobile data network, and the newer version of the firmware is transmitted to the device through the Wifi link between the mobile Wifi device and the device.

[0051] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0052] In order to illustrate the above technical solution of the present application, a specific embodiment is provided below for illustration.

[0053] When upgrading the firmware of devices such as inverters, mobile Wifi devices are usually used to transmit the latest version of the firmware. When the user initiates an upgrade request command, the server will receive this command and compare the firmware version on the server with the current firmware version of the device. If there is a newer firmware version on the server, the newer version of the firmware is sent to the mobile Wifi device via the mobile data network, and then the mobile Wifi device transmits the firmware to the device to be upgraded via the Wifi link. After the device to be upgraded receives the firmware, it will feedback the upgrade status, allowing the user to track the upgrade progress in real time.

[0054] However, when updating the upgrade status, if the upgrade status is judged only based on the download progress of the device or the stability of the communication connection between the device and the mobile Wifi device, inaccurate results may be obtained. This status update method may not truly reflect the actual completion of the firmware upgrade, thereby affecting the precise control and monitoring of the device upgrade process. Therefore, a more precise method is needed to ensure the accuracy of the upgrade status and the reliability of the upgrade process.

[0055] Figure 1 A schematic diagram of an implementation scenario of a method for determining a firmware upgrade status provided in an embodiment of the present application. The scenario includes a mobile Wifi device, a device to be upgraded, a server, and a user terminal. Among them, the mobile Wifi device includes a mobile communication module and a Wifi module. The mobile Wifi device can be connected to the server through the mobile communication module, and connected to the device to be upgraded through the Wifi module. The user terminal can be connected to the server through the mobile Wifi device, or the user terminal can also be directly connected to the server through a mobile communication network. The user terminal can upload the firmware to be upgraded (usually the latest version of the firmware) to the server. After the user terminal triggers the firmware upgrade instruction, the server can send a firmware upgrade instruction to the device to be upgraded through the mobile Wifi device, obtain the firmware version information cached by the device to be upgraded, compare the cached firmware version information with the version information of the firmware to be upgraded, and when it is determined that an upgrade is required, the server will update the version of the firmware and transmit it to the device to be upgraded through the mobile Wifi device to complete the firmware upgrade of the device to be upgraded, and return the upgrade status to the server, and transmit the upgrade status to the user terminal, so that the user can understand the upgrade progress in time.

[0056] Figure 2 A schematic diagram of the implementation flow of a method for determining a firmware upgrade status provided in an embodiment of the present application, the execution subject of the method may include a server and other devices, and the method is described in detail as follows:

[0057] In S201, a firmware upgrade instruction is sent to a device to be upgraded via a mobile Wifi device.

[0058] The mobile Wifi device in the embodiment of the present application may include portable Wifi, Wifi stick and other portable Wifi devices. Through the mobile Wifi device, convenient network services can be provided for the device to be upgraded, so as to obtain the firmware to be updated from the server, and the firmware of the device to be upgraded can be updated according to the downloaded firmware.

[0059] The device to be upgraded in the embodiment of the present application may include a device with a Wifi module, such as an inverter. In general, the device to be upgraded is within the coverage of home Wifi or public Wifi, and the staff needs to upgrade it through a mobile Wifi device. For example, for the inverter in a distributed photovoltaic power station, the staff needs to use a mobile Wifi device, including a Wifi stick, to upgrade the inverter.

[0060] When the server sends a firmware upgrade instruction to the device to be upgraded, the firmware upgrade instruction can be triggered when the server receives an updated version of the firmware uploaded by the user terminal, or the firmware version is updated through other means, or the server can send the firmware upgrade instruction to the device to be upgraded through a mobile Wifi device after receiving the firmware upgrade instruction issued by the user terminal.

[0061] In S202, the firmware type of the firmware to be upgraded included in the firmware upgrade instruction is determined.

[0062] The firmware types in the embodiments of the present application may have different types of firmware types depending on the device to be upgraded. For example, when the device to be upgraded is an inverter, the firmware types included in the device to be upgraded may include AC (Alternating Current in English, alternating current in Chinese) side firmware, DC (Direct Current in English, direct current in Chinese) side firmware, BMS (Battery Management System in English, battery management system in Chinese) firmware, and MPU (Microprocessor Unit, microprocessor unit in Chinese) firmware, etc.

[0063] The AC-side firmware is responsible for managing the inverter's conversion of DC into AC and synchronization with the grid, including the use of pulse width modulation (PWM) technology to control the on and off time of the switching devices to generate the required AC output waveform.

[0064] The DC-side firmware is used for the inverter's DC input management, including the implementation of maximum power point tracking and interface control with DC power sources such as solar panels.

[0065] The BMS firmware is responsible for monitoring and managing the status of the battery pack, including battery cell voltage and temperature monitoring, battery balancing, and charge and discharge management.

[0066] The MPU firmware can be used in the inverter to implement advanced control methods, including fuzzy logic control methods or neural network control methods, to optimize the performance and efficiency of the inverter.

[0067] This is not limited to inverters; other types of devices to be upgraded may have different firmware types.

[0068] In S203, the delay time corresponding to the firmware type of the firmware to be upgraded is determined according to the preset correspondence between the firmware type and the delay time.

[0069] The delay time is the duration of the effective upgrade status detection after the firmware upgrade instruction is sent.

[0070] The delay time refers to the delay time after the server sends the firmware upgrade instruction. Within the time range of the delay time, it can be used to detect the effective upgrade status, including the upgrade success status and the upgrade failure status. If it exceeds the delay time, it is directly determined as the upgrade failure status.

[0071] The corresponding relationship between the firmware type and the delay time in the embodiment of the present application can be set in advance by the staff. For example, the corresponding relationship between the firmware type and the delay time can be determined based on the empirical statistical data of the upgrade time required by the firmware type.

[0072] In a possible implementation, the embodiment of the present application can determine the delay time corresponding to the firmware type according to the firmware transmission path corresponding to the firmware type, so as to determine the upgrade result status of the device to be upgraded according to the delay time. The method for determining the delay time corresponding to the firmware type according to the firmware transmission path corresponding to the firmware type can be as follows: Figure 3 As shown, including:

[0073] In S301, a firmware transmission path corresponding to the firmware type of the firmware to be upgraded is determined.

[0074] When the device to be upgraded is an inverter, the firmware types of the firmware to be upgraded may include AC side firmware, DC side firmware, PMU firmware and BMS firmware. The locations of the firmware to be upgraded for each firmware type are different, so the firmware transmission paths corresponding to each firmware are also different.

[0075] Generally, during the inverter upgrade process, the downloaded firmware needs to pass through the monitoring PMU component and then be sent to the AC side component, DC side component or BMS component. After the PMU component obtains the firmware to be upgraded, if the firmware to be upgraded is used to upgrade the PMU component, it does not need to be forwarded and can be directly used for PMU component upgrade, and the time used to upgrade the PMU component is shorter. When the firmware to be upgraded is used to upgrade the AC component or DC component, the firmware to be upgraded needs to pass through the PMU component first, and then be sent to the AC component or DC component through internal transmission, and then the AC component or DC component is upgraded. Since the DC component or AC component is located inside the inverter, when the deviation of the data volume of different firmware to be upgraded is within a predetermined range, the upgrade time of the AC component or DC component is longer than the upgrade time of the PMU component. When upgrading the BMS components, after the inverter downloads the firmware to be upgraded of the BMS components, it needs to be forwarded to the BMS components through the PMU components. And because the amount of data transmitted each time when the BMS components set the transmission data frame is small, such as 256b, therefore, compared with the AC side components, DC side components and PMU components, the upgrade time of the BMS components is the longest.

[0076] When determining the firmware delivery path corresponding to each firmware type, the following may be included:

[0077] The first firmware transmission path of the PMU firmware is determined to be transmitted from the mobile Wifi device to the MPU component.

[0078] It is determined that the second firmware transmission path of the AC side firmware is transmitted from the mobile Wifi device to the MPU component, and then sent to the AC side component in the MPU component.

[0079] After determining that the third firmware transmission path of the DC side firmware is transmitted from the mobile Wifi device to the MPU component, it is sent down to the DC side component in the MPU component.

[0080] It is determined that the fourth firmware transmission path of the BMS firmware is transmitted from the mobile Wifi device to the MPU component, and then forwarded to the BMS component through the MPU component.

[0081] In S302, the delay time after the firmware upgrade instruction is sent is determined according to the firmware transmission path.

[0082] According to the difference of each firmware transmission path, the time required to complete the firmware upgrade of different transmission paths is also different. When the deviation of the firmware data volume meets the predetermined deviation range, the longer the firmware transmission path is, the longer the time required to complete the firmware upgrade is. Therefore, different delay time lengths can be determined according to different firmware transmission paths, which may include:

[0083] According to the first firmware transmission path, a first delay time length of the PMU firmware after the firmware upgrade instruction is sent is determined.

[0084] According to the second firmware transmission path, a second delay time length of the AC side firmware after the firmware upgrade instruction is sent is determined.

[0085] According to the third firmware transmission path, a third delay time length of the DC-side firmware after the firmware upgrade instruction is sent is determined.

[0086] According to the fourth firmware transmission path, a fourth delay time length of the BMS firmware after the firmware upgrade instruction is sent is determined.

[0087] Among them, the first delay duration is shorter than the second delay duration, the first delay duration is shorter than the third delay duration, the second delay duration is shorter than the fourth delay duration, and the third delay duration is shorter than the fourth delay duration.

[0088] That is, the longer the path for transmitting the firmware to the corresponding component of the device to be upgraded is, the more transmission time is required to complete the firmware transmission. Therefore, the longer the firmware transmission path is, the longer the time required to complete the firmware upgrade is, and the longer the delay time needs to be set.

[0089] In S204, the upgrade result status of the firmware to be upgraded is determined according to the cache version information of the device to be upgraded and the delay time.

[0090] The upgrade result status includes the upgrade success status and the upgrade failure status. The upgrade success status indicates that the device to be upgraded has successfully received and successfully installed the data of the firmware to be upgraded. The upgrade failure status indicates that the device to be upgraded has not successfully installed the firmware to be upgraded. The upgrade failure status may include that the firmware to be upgraded has been successfully received, but has not been transmitted to the component to be upgraded corresponding to the firmware to be upgraded, or has been successfully transmitted to the component to be upgraded but has failed to be successfully installed due to other reasons.

[0091] In order to improve the accuracy of the upgrade result status, the embodiment of the present application determines the upgrade result status based on the delay duration and cached version information, which can effectively reduce the error in the upgrade result status determined by the instruction returned by the mobile Wifi device and improve the user experience. After determining different delay durations according to different firmware types, the upgrade result status of the firmware to be upgraded can be determined within the delay duration based on the cached version information of the device to be upgraded. Specifically, Figure 4 As shown, including:

[0092] In S401, the cache version information of the device to be upgraded is obtained within the time range of the delay time.

[0093] The delay duration in the embodiment of the present application is the duration of the detection for determining that the firmware is in a valid upgrade state, and the duration is the duration starting after the firmware upgrade instruction is sent. If the delay duration is exceeded, it can be determined that the upgrade result state of the firmware to be upgraded is an upgrade failure state, and a status indicator of firmware upgrade failure can be sent to the user terminal.

[0094] If the device to be upgraded is in an upgrading state, the cached version information of the device to be upgraded is the version information of the firmware currently in the upgrading state.

[0095] In order to further improve the accuracy of the upgrade result status and reduce the possibility of mistakenly generating an upgrade failure status due to communication stability, the embodiment of the present application can also further obtain the status information of the cached version of the device to be upgraded after sending the firmware upgrade instruction for a predetermined time (the predetermined time is less than the delay time), and the status information may include the existence of updates within the predetermined time and the absence of updates within the predetermined time. If there is no update within the predetermined time, it means that the firmware to be upgraded has not been received, and the upgrade result status is updated to the upgrade failure status. If there is an update within the predetermined time, S402 can be continued to detect the consistency of the cached version information, thereby reducing the probability of mistakenly confirming the upgrade failure status due to network instability.

[0096] In S402, when the cache version information is consistent with the firmware version information included in the firmware upgrade instruction, the upgrade process is continued, and the upgrade result status is updated to an upgrade success status according to the upgrade success response result returned by the device to be upgraded.

[0097] In a possible implementation, during the firmware upgrade process of the device to be upgraded, there may be multiple different firmwares to be upgraded. In order to reduce the impact of other firmware upgrades on the upgrade result status, the cache version information can be compared with the firmware version information included in the firmware upgrade instruction to determine whether the two are the same firmware version. If they are the same firmware version, the upgrade process can continue, including continuing to send data of the firmware to be upgraded to the device to be upgraded, etc., until the download and installation of the firmware to be upgraded is completed, and a response result of the successful firmware upgrade returned by the device to be upgraded is received, and the upgrade result status is updated to a successful status according to the response result.

[0098] In S403, when the cache version information is inconsistent with the firmware version information included in the firmware upgrade instruction, the upgrade result status is updated to an upgrade failure status.

[0099] If the cached version information is inconsistent with the firmware version information included in the firmware upgrade instruction, it means that the firmware version information currently cached by the device to be upgraded is data of other firmware and is currently in the process of upgrading other firmware. Therefore, the upgrade result status of the upgrade failure status can be returned.

[0100] Since the embodiment of the present application determines the upgrade result status based on the comparison between the cached version information and the firmware version information of the firmware upgrade instruction within the delay period, it is not necessary to determine the upgrade result status based on the stability of the network status, whether the download is successful, etc., which can effectively improve the accuracy of the upgrade result status and is conducive to upgrading the device according to the upgrade status result.

[0101] In a possible implementation, in addition to determining the upgrade result status based on the delay duration and cached version information, the embodiment of the present application can directly determine the upgrade process status of the firmware to be upgraded based on the intermediate status returned by the mobile Wifi device for other intermediate states, including intermediate states such as starting to upgrade, starting to download, downloading, downloading completed, and downloading failed.

[0102] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
