3results about How to "Reliable upgrade" patented technology

This application discloses a firmware upgrade system, method, storage medium, and embedded device for embedded devices. The firmware upgrade system includes a main control computer and multiple levels of control modules. The main control computer establishes a data transmission link with the first-level control module, and wired or wireless data transmission links are established between every two adjacent control modules. In response to a firmware upgrade request, the main control computer determines the target control module to be upgraded and distributes the firmware upgrade data level by level along the data transmission links from the main control computer to the target control module, enabling the target control module to perform a firmware upgrade based on the upgrade data. This system can achieve unified upgrades of control modules at all levels in a hybrid topology or independent upgrades of control modules at each level. Its topology and firmware distribution method can flexibly adapt to the firmware upgrade needs of various embedded devices, ensuring safe and reliable upgrades for embedded devices.

The application discloses an automatic upgrading method, system, platform and storage medium suitable for an intermediate version of an ONU. The method is used for obtaining an ONU version upgrade creation instruction, generating at least two ONU version upgrade rules in real time according to the creation instruction, obtaining source version data information and target version data information respectively, and matching data information between the source version and the target version in real time. According to the matching condition of the source version and the target version, the ONU version upgrade is completed in real time, and the system, platform and storage medium corresponding to the method can be changed from manual upgrading to automatic upgrading. The OLT is used for creating ONU automatic upgrading rules, and the CTC OAM is used for performing spiral automatic upgrading by matching an ONU model id and a software version number, so that the artificial maintenance cost is reduced, the failure rate caused by artificial upgrading is reduced, and the intermediate version of the ONU can be reliably, comprehensively and quickly upgraded.

This invention discloses a software upgrade method, system, device, and medium for a controller. In this software upgrade method, a communication connection is established between the controller and a host computer. The method can be applied to the host computer, which acquires the controller's associated parameter information, obtains a target software upgrade package matching the controller based on the associated parameter information, and sends it to the controller. The host computer receives several feedback messages sequentially sent by the controller during the upgrade operation based on the target software upgrade package. Different feedback messages correspond to different upgrade processing operations, and the controller's software upgrade status is determined based on the feedback information. This software upgrade method can also be applied to the controller itself. By real-time monitoring of each stage of the software upgrade process, this invention enhances the information interaction between the controller and the host computer during the software upgrade process, improves the efficiency and success rate of the software upgrade, and ensures the stability and reliability of the software upgrade within the controller.
