The invention provides a nuclear power plant radiation monitoring server platform safety verification method and system. And when an old server with redundant setting is replaced, obtaining configuration information, and carrying out configuration and offline simulation verification on a new server. After verification is passed, staged online verification is carried out: in the first stage, an old server is replaced by a first new server, and batch online verification is completed by carrying out communication data packet comparison with another old server which is still online; and in the second stage, another old server is replaced by a second new server, and the same batch comparison verification is carried out. And after all verification is passed, formally switching to two new servers. According to the method, through staged cooperation and batch verification, safe and undisturbed replacement and upgrading of the server platform are realized on the premise of ensuring continuous and safe operation of the nuclear power station.

The invention discloses a method for supporting multi-protocol firmware upgrading, and relates to the technical field of intelligent equipment of the Internet of Things, and the method comprises the specific steps of file package generation and issuing, adaptation degree calculation and association establishment, upgrading strategy matching, transmission data volume calculation and upgrading evaluation and closed loop. Through the firmware upgrading technology supporting multiple protocols, the efficiency and flexibility of firmware upgrading are improved, the cloud server is used for collecting information of all intelligent devices accessed by the target home gateway and generating the standardized upgrading file package, the target of'one-time generation and multi-device application 'is achieved, meanwhile, the upgrading file package is intelligently analyzed through the home gateway, and the upgrading efficiency is improved. According to the method, the multi-protocol adaptation degree is calculated, and the equipment-protocol type-corresponding firmware data association mapping table is established, so that corresponding upgrading strategies are matched for different intelligent equipment, and the intelligent upgrading strategy matching mechanism not only reduces manual intervention, but also greatly improves the upgrading efficiency, so that firmware upgrading is more flexible and efficient.

This application discloses a firmware upgrade method, device, storage medium, and program product, relating to the field of server technology. It ensures module storage alignment between versions through fixed-length module design, eliminating the impact of address drift; generates reversible difference data through XOR operations, enabling the same differential packet to support upgrades and rollbacks, simplifying version management and reducing storage overhead; verifies the compatibility of the differential packet with the device firmware structure before upgrades through layout verification of the metadata area and verification area, preventing accidents caused by version errors; and performs lightweight operations only on the difference bits through in-situ bit-level modification, reducing resource consumption and improving upgrade efficiency. These features work synergistically to reduce data volume and alleviate network pressure during transmission, enhance operational security during verification, and achieve efficient upgrades and reliable rollbacks during execution. It is suitable for weak network environments, large-scale concurrent upgrades, and high-reliability embedded firmware management scenarios.

The embodiment of the invention provides a vehicle upgrading method and device, vehicle equipment, a medium and a product. The method comprises the steps that under the condition that the vehicle is in a first mode, a control unit of the vehicle is awakened in a timed mode so as to search a wireless network of a vehicle storage library, and the first mode is used for representing that the vehicle is located in the vehicle storage library; under the condition that the wireless network is searched, the control unit is connected to the wireless network of the vehicle storage library; a remote update operation is performed by a control unit of the vehicle. According to the method provided by the embodiment of the invention, the vehicle updating efficiency can be improved, and the vehicle updating cost can be reduced.
