[0002] The energy storage valve control protection device adopts a multi-plug design. In order to enable the plug to implement new functions and solve problems encountered in applications, it is inevitable to upgrade the plug. Currently, when upgrading the software of the lower-level microcontroller unit (MCU) plug, the product needs to be disassembled and a simulator is used for upgrading. The upgrade steps are relatively cumbersome and time-consuming. Moreover, when the application program in the plug is in an infinite loop or the application program jump bootloader entry is damaged, the internal plug cannot be upgraded. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a method, device, system, and terminal device for plug-in upgrade, which solves the problem that the product must be disassembled to upgrade the software in the plug in the prior art.

[0004] In a first aspect, the present application provides a method for plug-in upgrade. A bootloader and an application program are loaded on the plug. The method for plug-in upgrade includes:

[0005] Start the bootloader, read the startup flag from the plug and judge the startup flag;

[0006] In response to the startup flag being a warm start, accumulate the number of warm starts;

[0007] Based on the accumulated number of warm starts, determine that the bootloader or the application program in the plug establishes a communication connection with the server to receive the target upgrade package sent by the server;

[0008] The bootloader in the plug upgrades the application program based on the target upgrade package.

[0009] In the technical solution of the embodiment of the present application, when the startup flag in the plug is a warm start, the number of warm starts is counted and accumulated, and based on the accumulated number of warm starts, it is determined that the bootloader in the plug mobilizes the application program to establish a communication connection with the server, or the bootloader directly establishes a communication connection with the server without mobilizing the application program, so that the plug obtains the target upgrade package sent by the server, and the bootloader upgrades the application program based on the target upgrade package, thereby realizing the online upgrade of the application program without disassembling the product and simplifying the upgrade process.

[0010] In some embodiments, based on the cumulative number of warm boots, determining that the bootloader or application in the plugin establishes a communication connection with the server to receive the target upgrade package sent by the server includes:

[0011] In response to the cumulative number of warm boots reaching a preset number, the bootloader does not need to invoke the application, and the bootloader establishes a communication connection with the server;

[0012] The bootloader in the plugin receives the target upgrade package sent by the server.

[0013] In the technical solution of the embodiments of the present application, when the cumulative number of warm boots reaches the preset number, it indicates that the application has a fault. The bootloader does not need to start the application, and the bootloader can directly establish a communication connection with the server to receive the target upgrade package sent by the server, improving the situation where the application in the plugin has a fault and cannot be upgraded.

[0014] In some embodiments, the plugin upgrade method further includes:

[0015] In response to the startup flag being a cold boot, the bootloader invokes the application, and the application establishes a communication connection with the server;

[0016] Based on the cumulative number of warm boots, determining that the bootloader or application in the plugin establishes a communication connection with the server to receive the target upgrade package sent by the server includes:

[0017] In response to the cumulative number of warm boots not reaching the preset number, the bootloader invokes the application, and the application establishes a communication connection with the server;

[0018] The application queries the current running information of the application;

[0019] Based on the current running information of the application, determine the target upgrade package of the application.

[0020] In the technical solution of the embodiments of the present application, when the startup flag is a cold boot, the bootloader directly invokes the application to establish a communication connection with the server; when the cumulative number of warm boots does not reach the preset number, the bootloader invokes the application, and the application establishes a communication connection with the server, enabling the application to query the current running information, and then obtaining the target upgrade package of the application based on the current running information, facilitating the bootloader to upgrade the application of the plugin based on the target upgrade package, reducing the complexity of the upgrade, and improving the success rate of the upgrade.

[0021] In some embodiments, the current running information includes the current version number;

[0022] The application queries the current running information of the application, including:

[0023] The application programs of each plugin respectively send the feature information of the plugin to the server; the feature information includes the location information of the plugin.

[0024] The application programs of each plugin respectively receive the query instructions sent by the server, and query the current version number of the corresponding application program based on the query instructions.

[0025] The application program of the plugin sends the current version number of the application program to the server for the server to save.

[0026] In the technical solution of the embodiment of the present application, the application programs of each plugin send the feature information of the plugin to the server, so that the server can implement obtaining the current version numbers of the application programs in multiple plugins, which is convenient for subsequent upgrading of multiple plugins; at the same time, the number of plugins can also be adjusted.

[0027] In some embodiments, determining a target upgrade package for an application program based on the current running information of the application program includes:

[0028] Receiving an upgrade package sent by the server; the upgrade package includes files to be upgraded and a verification code; the upgrade package is an installation package obtained by the server according to the current version number of the application program after receiving the upgrade instruction sent by the client.

[0029] In response to the verification code being consistent with the preset information, taking the file to be upgraded as the target upgrade package of the application program.

[0030] The boot program in the plugin upgrades the application program based on the target upgrade package, including:

[0031] The boot program overwrites the application program based on the file to be upgraded to upgrade the application program.

[0032] In the technical solution of the embodiment of the present application, the plugin verifies the verification code in the upgrade package sent by the server to detect whether the file to be upgraded is correct, improving the success rate of the application program upgrade.

[0033] In some embodiments, after the step of the boot program in the plugin upgrading the application program based on the target upgrade package, it further includes:

[0034] The plugin queries the upgrade version number of the upgraded application program.

[0035] In response to not querying the upgrade version number of the application program, it indicates that the application program has fallen into an infinite loop.

[0036] Reset the plugin to start the boot program.

[0037] In the technical solution of the embodiment of the present application, by querying the upgrade version number of the application program, when the upgrade version number of the application program is not queried, it indicates that the upgrade of the application program fails, and the current application program falls into an infinite loop. The plug-in is reset to the bootloader, so that the plug-in can start the bootloader again to upgrade the application program.

[0038] In some embodiments, the current running information includes the current version number;

[0039] After the step of the bootloader in the plug-in upgrading the application program based on the target upgrade package, it further includes:

[0040] In response to querying the upgrade version number of the application program, compare the upgrade version number with the current version number;

[0041] In response to the upgrade version number corresponding to the application program being consistent with the current version number, it indicates that the entry for the application program to jump to the bootloader is damaged;

[0042] Reset the plug-in to the bootloader.

[0043] In the technical solution of the embodiment of the present application, by querying the upgrade version number of the application program in the plug-in and comparing the queried upgrade version number of the application program with the current version number before the upgrade, when the upgrade version number is consistent with the current version number, it indicates that the upgrade of the application program fails, and the entry for the application program to jump to the bootloader is damaged. The plug-in is reset to the bootloader, so that the plug-in can start the bootloader again to upgrade the application program.

[0067] In this embodiment, the plug-in refers to a Microcontroller Unit (MCU), also known as a Single Chip Microcomputer or a microcontroller. It appropriately reduces the frequency and specifications of the Central Processing Unit (CPU), and integrates peripherals such as memory, timer, USB, A / D conversion, UART, PLC, DMA, and even the LCD driver circuit on a single chip to form a chip-level computer for different combinations of control in different application scenarios.

[0068] The energy storage valve control protection device adopts a multi-plug-in design. With the continuous change of requirements, the functions of the plug-ins need to be continuously updated and upgraded to meet the requirements in applications. Since the plug-ins are set inside the product, when upgrading the plug-ins, it is necessary to remove the cover of the product, update the boot program in the plug-ins through an emulator, and then upgrade the application programs on the plug-ins. The upgrade steps are cumbersome and time-consuming.

[0069] This embodiment provides a method for upgrading a plug-in, where a boot program and an application program are loaded on the plug-in. The method for upgrading the plug-in includes the following steps.

[0070] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of the method for upgrading a plug-in provided by an embodiment of the present application.

[0071] S1: Start the boot program, read the start flag from the plug-in and judge the start flag.

[0072] S2: In response to the start flag being a warm start, accumulate the number of warm starts.

[0073] S3: Based on the accumulated number of warm starts, determine that the boot program or the application program in the plug-in establishes a communication connection with the server to receive the target upgrade package sent by the server.

[0074] S4: The boot program in the plug-in upgrades the application program based on the target upgrade package.

[0075] In the technical solution of the embodiment of the present application, when the startup identifier in the plugin is a hot startup, the number of hot startups is counted and accumulated, and based on the accumulated number of hot startups, it is determined that the bootstrap program in the plugin mobilizes the application to establish a communication connection with the server, or the bootstrap program directly establishes a communication connection with the server without mobilizing the application, so that the plugin obtains the target upgrade package sent by the server, and the bootstrap program upgrades the application based on the target upgrade package, thereby realizing the upgrade of the application without opening the cover of the product and without updating the bootstrap program, and simplifying the upgrade process.

[0076] In some embodiments, the step of reading the startup identifier from the plugin and judging the startup identifier in S1 specifically includes the following implementation manners.

[0077] By starting the bootstrap program in the plugin, each time the bootstrap program in the plugin is started, there is a corresponding hot startup variable in the plugin. Among them, the hot startup variable is the startup identifier stored in the plugin. Starting the plugin in the shutdown state is called a cold startup; starting the plugin when it is powered on is called a hot startup.

[0078] When the hot startup variable corresponding to the current startup of the bootstrap program in the plugin is the set value, it is determined that the startup identifier corresponding to the current startup is a hot startup; when the hot startup variable corresponding to the current startup of the bootstrap program in the plugin is inconsistent with the set value, it is determined that the startup identifier corresponding to the current startup is a cold startup.

[0079] When the startup identifier of the current startup of the bootstrap program is a hot startup, add 1 to the count of hot startups to accumulate the number of hot startups.

[0080] In one embodiment, the plugin upgrade method further includes: in response to the startup identifier being a cold startup, the bootstrap program mobilizes the application, and the application establishes a communication connection with the server.

[0081] Specifically, when the startup identifier of the current startup of the bootstrap program is a cold startup, the hot startup variable corresponding to the current startup is reset so that the hot startup variable corresponding to the current startup is the set value.

[0082] When a failure occurs in the application in the plugin itself or a communication failure occurs between the plugin and other ports, the application cannot be upgraded. In this embodiment, by accumulating the above-mentioned accumulated hot startup times, the application can be directly updated online after a preset number of times.

[0083] In some embodiments, the step of determining to receive the target upgrade package sent by the server in S3 specifically includes the following implementation manners.

[0084] In a specific embodiment, in response to the cumulative number of warm boots reaching a preset number, the bootloader does not need to start the application. The current application has a fault and the target upgrade package cannot be obtained through the application. The bootloader establishes a communication connection with the server so that the bootloader in the plugin can receive the target upgrade package sent by the server.

[0085] In the technical solution of the embodiment of the present application, when the cumulative number of warm boots reaches the preset number, it indicates that the application has a fault. The bootloader does not need to start the application. The bootloader can directly establish a communication connection with the server and receive the target upgrade package sent by the server, improving the situation where the application in the plugin has a fault and the application cannot be upgraded.

[0086] In a specific embodiment, the specific steps of obtaining the target upgrade package through the application are as follows.

[0087] Please refer to Figure 2 , Figure 2 For Figure 1 a schematic flowchart of a specific embodiment of step S3 in a plugin upgrade method provided.

[0088] S31: In response to the cumulative number of warm boots not reaching the preset number, the bootloader starts the application, and the application establishes a communication connection with the server.

[0089] S32: The application queries the current running information of the application.

[0090] Specifically, after the application establishes a communication connection with the server, the applications of each plugin respectively actively send the feature information of the plugin to the server; the feature information includes the location information and type of the plugin, and the type of the plugin can include an interface board, an open circuit board, etc. The server saves the feature information of each plugin respectively. Among them, the location information of the plugin is the slot set for the plugin.

[0091] The server receives the feature information sent by each plugin, and the server sends a query instruction to each plugin. Among them, the query instruction is to query the current version number of the application in the plugin.

[0092] The applications of each plugin respectively receive the query instruction sent by the server, and query the current version number of the corresponding application based on the query instruction; the application of the plugin sends the current version number of the application to the server, and the server receives the current version numbers sent by each plugin and saves them so that the server can associate the feature information of the plugin with the current version number of the application.

[0093] In the technical solution of the embodiment of the present application, the application programs of each plugin send the characteristic information of the plugin to the server, so that the server can implement obtaining the current version numbers of the application programs in multiple plugins, which is convenient for subsequent upgrading of multiple plugins; at the same time, the number of plugins can also be adjusted.

[0094] When the client needs to query the characteristic information of each plugin and / or the current version number of the application program corresponding to the plugin, it can send a query request to the server. After receiving the query request, the server displays the characteristic information of each plugin and the current version number of the application program corresponding to the plugin to the user.

[0095] The user selects the upgrade package corresponding to the plugin according to the displayed characteristic information of the plugin and the current version number of the application program. The upgrade package is sent to the server through the client so that the server can save the upgrade package. The upgrade package includes the file to be upgraded and the verification code. After receiving the upgrade package, the server verifies the file to be upgraded in the upgrade package based on the verification code.

[0096] When the verification code is consistent with the preset verification code, the file to be upgraded is correct, and the file to be upgraded is saved to the area to be upgraded of the server. When the verification code is consistent with the preset verification code, the file to be upgraded is incorrect. The verification result obtained by the server is sent to the client. Among them, the preset verification code is pre-stored in the server. By setting the preset verification code, the security of data transmission can be improved and the problem of misoperation can be improved.

[0097] When the client detects that the current version number corresponding to the plugin is inconsistent with the version number corresponding to the file to be upgraded, the client sends an upgrade instruction to the server. After receiving the upgrade instruction sent by the client, the server generates an upgrade package based on the file to be upgraded and the check code and sends it to the corresponding plugin. The client in this embodiment can be a display panel with a communication function. The user side can remotely update or send the file to be upgraded to the server. The server can send the upgrade package to the application program in the plugin according to the preset time. So as to facilitate the maintenance personnel to control the upgrade time of the plugin.

[0098] S33: Determine the target upgrade package of the application program based on the current running information of the application program.

[0099] Specifically, the application program within the plugin receives the upgrade package sent by the server. The upgrade package includes the file to be upgraded and the verification code; the upgrade package is the installation package obtained by the server according to the current version number of the application program after receiving the upgrade instruction sent by the client; in response to the verification code being consistent with the preset information, the file to be upgraded is used as the target upgrade package of the application program, and the verification result is sent to the server for storage. In response to the verification code being inconsistent with the preset information, the file to be upgraded is incorrect, and the verification result is sent to the server, and the server sends the verification result to the client. Among them, the preset information is pre-stored in each plugin. By setting the preset information, the security of data transmission can be improved and the problem of misoperation can be alleviated.

[0100] In the technical solution of the embodiment of the present application, when the startup flag is a cold startup, the bootstrap program directly invokes the application program to establish a communication connection with the server; when the cumulative number of hot startups does not reach the preset number, the bootstrap program invokes the application program, and the application program establishes a communication connection with the server, enabling the application program to query the current running information, and then obtaining the target upgrade package of the application program based on the current running information, which facilitates the bootstrap program to upgrade the application program of the plugin based on the target upgrade package, reduces the complexity of the upgrade, and improves the success rate of the upgrade.

[0101] In some embodiments, the steps of upgrading the application program in S4 specifically include the following implementation manners.

[0102] Specifically, the bootstrap program upgrades the application program by overwriting the application program with the file to be upgraded.

[0103] In the technical solution of the embodiment of the present application, the plugin verifies the verification code in the upgrade package sent by the server to detect whether the file to be upgraded is correct, which improves the success rate of the application program upgrade.

[0104] In some embodiments, after the step of the bootstrap program in the plugin upgrading the application program based on the target upgrade package, it further includes: the plugin queries the upgrade version number of the upgraded application program; in response to the upgrade version number of the application program not being queried, it indicates that the application program has fallen into an infinite loop; the plugin is reset to the startup bootstrap program.

[0105] In the technical solution of the embodiment of the present application, by querying the upgrade version number of the application program, when the upgrade version number of the application program is not queried, it indicates that the upgrade of the application program has failed, and the current application program has fallen into an infinite loop, and the plugin is reset to the startup bootstrap program, so as to facilitate the plugin to start the bootstrap program again to upgrade the application program.

[0106] In some embodiments, after the step of upgrading the application program by the bootstrap program in the plugin based on the target upgrade package, the following steps are further included: in response to querying the upgrade version number of the application program, comparing the upgrade version number with the current version number; in response to the upgrade version number corresponding to the application program being consistent with the current version number, it indicates that the entry for the application program to jump to the bootstrap program is damaged; resetting the plugin to start the bootstrap program. Wherein, the current version number is the version number of the application program before the upgrade.

[0107] In the technical solution of the embodiment of the present application, by querying the upgrade version number of the application program in the plugin and comparing the queried upgrade version number of the application program with the current version number before the upgrade, when the upgrade version number is consistent with the current version number, it indicates that the upgrade of the application program fails, the entry for the application program to jump to the bootstrap program is damaged, and the plugin is reset to start the bootstrap program, so as to facilitate the plugin to start the bootstrap program again to upgrade the application program.

[0108] Through the above real-time method, when a failure occurs in the application program in the plugin, it can be reset by an external watchdog so that the plugin starts the bootstrap program again to upgrade the application program.

[0109] Based on the above Figure 1 and Figure 2 corresponding to the plugin upgrade method described in the embodiment, the following is an embodiment of the device of the present disclosure, which can be used to execute the method embodiment of the present disclosure.

[0110] Please refer to the attached Figure 3 , Figure 3 which is a schematic framework diagram of an embodiment of the plugin upgrade device provided by the present invention.

[0112] The start module 61 is used to start the bootstrap program, read the start flag from the plugin and judge the start flag.

[0113] The counting module 62 is used to accumulate the number of warm starts in response to the start flag being a warm start.

[0114] The analysis module 63 is used to determine that the bootstrap program or the application program in the plugin establishes a communication connection with the server based on the accumulated number of warm starts, so as to receive the target upgrade package sent by the server.

[0115] The upgrade module 64 is used to upgrade the application program by the bootstrap program in the plugin based on the target upgrade package.

[0116] In the technical solution of the embodiment of the present application, when the start flag in the plug-in is a warm start, the number of warm starts is counted and accumulated, and based on the accumulated number of warm starts, it is determined that the bootstrap program in the plug-in either invokes the application program to establish a communication connection with the server, or the bootstrap program directly establishes a communication connection with the server without invoking the application program, so that the plug-in obtains the target upgrade package sent by the server, and the bootstrap program upgrades the application program based on the target upgrade package, thereby realizing the online upgrade of the application program without opening the cover of the product and simplifying the upgrade process.
