Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0020] like Figure 1-10 As shown, this embodiment of the invention provides a system status maintenance system for complex multi-platform devices, used for system maintenance and online upgrades of multiple devices on multiple platforms, including... Multiple status maintenance software units are used to perform status maintenance on different devices; The host computer software unit is used to realize data interaction, command interaction, and status interaction with various status maintenance software units; The configuration file functional unit is used to differentiate configurations between different systems; The data verification function unit is used to perform data verification. The online upgrade unit is used to upgrade different devices online.

[0021] The host computer software unit is deployed on the host computer and enables data interaction, command interaction, and status interaction with the status maintenance software in various devices of the system. The host computer software unit mainly includes interface display, data loading, communication protocols, data verification, and configuration files.

[0022] In some embodiments, the host computer software unit is configured to display the interface, save configuration information for different models and products, load upgrade data and verification files during the upgrade process using the configuration information, and communicate with the multiple status maintenance software units via Ethernet.

[0023] Interface display: Includes display area, configuration area, upgrade operation, status display, etc., with excellent operability; Data loading: Configures the storage directory of each configuration item, and loads upgrade data and verification files during the upgrade process; Communication protocol: Based on Ethernet communication interface, it uses communication protocols such as UDP, FTP, or WFTP for communication; Data verification: MD5-based data verification function ensures the correctness of data loading; Configuration file: Saves configuration information of different models and products in the form of configuration files.

[0024] In some embodiments, the interface display includes a display area, a configuration area, an upgrade operation display, and a device status display.

[0025] In some embodiments, the configuration file resides primarily in the host computer software unit. Each system can configure different components, modules, configuration items, IP addresses, data transmission protocols, configuration item storage directories, and other information according to its own composition status, offering the convenience of "configure once, use multiple times." The configuration file differentiates configurations between different systems, including different configurations for components, modules, sub-cards, and the number of modules, configuration items, configuration item types, and IP addresses in secondary and tertiary devices. Once the configuration file for the same model is configured and saved for the first time, it can be used for device status maintenance and online configuration item upgrades both in-house and in the field.

[0026] In some embodiments, the state maintenance software unit includes: UDP communication functional unit: used to complete the initialization, data sending and data receiving functions of UDP communication; Handshake function unit: used for handshaking with the host computer loader software; Command parsing function unit: used to parse the instructions transmitted by the host computer loader; Data transmission and parsing function unit: used for data transmission, parsing, and packet assembly between the host computer loader; Verification function unit: used for CRC check and MD5 check; Status reporting function unit: used for status reporting during handshake interaction, command interaction, and data interaction with the host computer.

[0027] The equipment status maintenance function primarily implements the function of querying the configuration item status of the target equipment, including version information, date information, etc. After the host computer software unit completes the equipment status query, it can determine whether upgrades, maintenance, or other operations are required based on the current version information of the configuration items, which can improve the work efficiency during field maintenance.

[0028] In some embodiments, the system performs two-level verification during implementation. This two-level verification method ensures the security and correctness of data interaction and transmission between the host computer software unit and various modules in the system. The first verification of the secondary verification occurs during the data loading process of the host computer software unit. It compares the loaded verification file with the local verification of the loaded data to ensure the correctness of the data during the host computer loading process. The second verification of the secondary verification occurs during the data transmission process between the host computer software unit and multiple status maintenance software units. The verification result transmitted by the host computer is compared with the local verification structure of the status maintenance software unit to ensure the correctness of the data during the data transmission process.

[0029] In some embodiments, a system status maintenance method for complex multi-platform devices is provided, including: S1: Configuration file for the host computer software unit; S2: The host computer and the target device complete a handshake; S3: Initiate data transfer via UDP or WFTP; S4: Determine whether the configuration item is the upgrade data of the current device or the upgrade data of the downstream device. If it is the upgrade data of the current device, proceed to S5; if it is the upgrade data of the downstream device, proceed to S6. S5: Perform the upgrade operation and report the upgrade results; S6. Data is distributed through a data interaction interface, and the upgrade operation is completed by downstream devices.

[0030] In some embodiments, the configuration file includes the IP address of the configuration item to be upgraded, the upgrade file directory, the burning address, and other content.

[0031] In some embodiments, the method further includes secondary verification. The first verification of the secondary verification is performed during the data loading process of the host computer software unit by comparing the loaded existing verification file with the local verification of the loaded data. The second verification of the secondary verification is performed during the data transmission process between the host computer software unit and multiple status maintenance software units by comparing the verification result transmitted by the host computer with the local verification structure of the status maintenance software unit.

[0032] In some embodiments, the state maintenance software consists of self-developed code and standard C language functions, which reduces the software's platform dependence and can be used in devices and products on various software development platforms.

[0033] The technical solutions provided in the above embodiments enable system status maintenance and online upgrades for complex equipment across multiple platforms, and facilitate status maintenance and online upgrades for different products, components, and modules within multiple systems. By standardizing and universalizing the system status maintenance and online upgrade methods, a user-friendly interface for equipment status maintenance and configuration item online upgrades is achieved, improving the convenience of equipment delivery and field support, enhancing operator workflow, and effectively saving labor and maintenance costs.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
