The invention relates to a blockchain-based domain name resolution system. The domain name resolution system adopts a hierarchical structure, including a top-level domain name chain network, a second-level domain name chain network, a future network node and an original DNS system network, and the top-level domain name chain links the second-level domain name chain network, the future network nodeand the original DNS system network; the top-level domain name chain network is used for each professional organization to deploy reliable server nodes to form an allied blockchain network, each nodeserver records information about all current top-level domain names, second-level domain name chain nodes, future network nodes, and existing DNS system root nodes; the second-level domain name chainnetwork is used for domain name registration and management, and records a record of all second-level domain names and subdomain names to which they belong; the future network node is used for storing metadata and indexes thereof in the future network. The resolution request is reduced and the efficiency of domain name resolution is effectively improved.

The invention provides a manufacture link multi-entity security synergy method based on a blockchain. The method comprises the following steps that: firstly, creating a root certificate by the CA (Certificate Authority), and verifying a new certificate which applies to be added into an entity; then, when a bid inviting entity in a trusted network initiates a synergy requirement, releasing requirement information and the signature of the requirement information to the trusted network through ''a smart contract for bid inviting releasing''; when a bidding entity receives the synergy requirement,through negotiation between a ''smart contract for communication key negotiation'' and the bid inviting entity, forming a shared secret key for decrypting the bidding information of the correspondingentity, and releasing encrypted bidding information and singed bidding information into the trusted network; after the bid inviting entity receives the bidding information, checking the credit information of the bidding entity, combining with the credit of the bidding entity to comprehensively evaluate all bidding information, and preferentially selecting one bidding entity as a bid winning entity to carry out synergy product production with the bid inviting entity; and finally, checking and accepting a product delivered by the bid winning entity by the bid inviting entity, and after the product is qualified, carrying out credit evaluation on the bid winning entity.

The invention provides an anti-interference matrix information encoding and decoding method for merchandise outer packaging, and relates to the circulation merchandise anti-counterfeiting tracing technology. According to the method, a discretization information encoding matrix is used as the unique unit packaging identity information, and data processing such as odd-even check, encoding, discretization, decoding and the like is conducted on the matrix information, so that information labels on circulation merchandises have the advantages of being unique, resistant to interference, large in capacity, traceable and the like. By the adoption of the anti-interference matrix information encoding and decoding method for merchandise outer packaging, on the one hand, traceability of the circulation merchandises is improved; on the other hand, decoding of the matrix information is facilitated, and query efficiency is improved.

The invention discloses a gas cylinder cross-regional cloud retracing management system and a method thereof. The system comprises a barcode reader-writer module, a functional department client module, a cloud server end module, and an inquire device. By means of the technologies such as internet of things, cloud calculation and barcode recognition, the barcode recognition technology is used for serving as the only way of gas cylinder recognition. Through the methods of traceability and the cloud calculation, gas cylinders are traced and managed during the processes of leaving a factory, resister and use, a complete gas cylinder management platform is established, transparency and the traceability of gas cylinder management are enhanced, and potential risks of the gas cylinders during the circulation process are lowered.

The invention relates to the technical field of internet of things and information processing, in particular to an RFID-based key point supervision method and system for a vegetable production process. Specifically, various supervised objects are subjected to unified coding and unified management in a vegetable production environment; and key data generated by the objects is acquired by adopting a unified data acquisition interface. Persons, materials, equipment and planting land parcels are associated through EPC tags by utilizing an RFID system; RFID door control is set in a key operation area, so that behaviors of the persons and associated operation information can be tracked in real time; and for agricultural products with quality or safety problems, operation batches with the problems can be located through a few records, and finally the persons or key points are traced. While the data is efficiently and accurately acquired, the data can be effectively supervised and traced, so that information of the vegetable production process is disclosed and the quality safety level of vegetable planting is improved.

The invention concerns a system for monitoring a flight control actuator of an aircraft, including:an actuator (1),sensors (3a-3d) in the actuator (1) to collect, during each flight of the aircraft, series of measurements of parameters relative to the said actuator,processing means (5) to calculate a set of damage indicators using, cumulatively, the series of measurements observed during each of the aircraft's successive flights, anda memory (7; 7a) to store the said set of damage indicators, where the said memory is integrated in the actuator.

The invention provides an automatic operation and maintenance management system for a college cloud computing center. The automatic operation and maintenance management system comprises a monitoring system, an operation and maintenance system and a management system, and is characterized in that the monitoring system is used for monitoring state information of a cloud computing center and judgingwhether the cloud computing center has an abnormal event or not; the operation and maintenance system is used for analyzing the data of the abnormal event when the monitoring system detects the abnormal event, and matching corresponding problem information from a problem library; and the management system is used for generating a corresponding operation and maintenance task according to the problem information, synchronizing the operation and maintenance task information to one or more user terminals corresponding to the operation and maintenance task, and updating the operation and maintenance task information according to feedback information of the user terminals. The automatic operation and maintenance management system can find the problems existing in the cloud computing center in time, realizes refined distribution of operation and maintenance roles and effective tracing of operation and maintenance tasks, and can improve the operation and maintenance management effect of the cloud computing center.
