The invention provides an RFID data acquisition method and device, and the method comprises the steps: enabling an RFID reading client to be connected with RFID equipment through a local HTTP service, receiving RFID tag information transmitted back by the RFID equipment through a callback interface, and carrying out the caching operation; the service system obtains RFID tag information through a local access address by using an HTTP interface, calls SSE service, controls opening or closing of message pushing of the SSE service through the HTTP interface, filters and encapsulates the cached RFID tag information through equipment coding, and performs rotation training on the SSE service through an asynchronous pushing thread so as to select a pushing mode of message pushing; and the service system reads the RFID tag array of the RFID reading client, carries out data check, and carries out data verification according to different service requirements. The data transmission and storage security can be effectively improved, the development cost is reduced, and the production efficiency is improved.

The invention provides a constellation software batch automatic upgrading method and system based on a laser link. Firstly, a ground control center generates a plurality of reconstruction packets, and the reconstruction packets are sequentially sent to a low-orbit earth satellite through a high-bandwidth microwave communication channel. Then, after the satellite receives the reconstructed packets, the correct reconstructed packets are reserved, and data increment packets are extracted at the same time; after the database receives the information that the satellite completes reconstruction, other satellites with software version numbers lower than those of the satellites in the constellation network to which the satellites belong are counted immediately, and the models of the satellites are transmitted to the satellites. And the satellite divides the incremental packet into a plurality of small packets, and after forward error correction coding and numbering processing, the small packets are multiplexed by using a DVB-S2 protocol and transmitted to a target satellite through an optimal laser link. The target satellite restores the complete incremental package, software updating is carried out in the dynamically determined idle time period, meanwhile, unified updating of ground database configuration is carried out, and therefore efficient and reliable batch upgrading is achieved.

The present application discloses an analog camera upgrade method and an upgrade device, the analog camera upgrade method comprising: after receiving a trigger instruction sent by a host computer, searching for a preset position in a video signal sent by the analog camera; corresponding to the preset position, sending an upgrade instruction to the analog camera to make the analog camera enter an upgrade mode, wherein after the analog camera enters the upgrade mode, corresponding to each video line in the video signal, the upgrade device can send data to the analog camera; in response to the analog camera successfully entering the upgrade mode, sending the upgrade package data sent by the host computer to the analog camera. The upgrade method provided by the present application can efficiently upgrade the analog camera without increasing the cost.

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.
