The application relates to the technical field of blockchains, in particular to a building information model cross-professional evidence storage and cooperation method based on a hierarchical alliance blockchain and application thereof. A central file and a blockchain synchronization strategy are proposed in units of single BIM models, BIM models are acquired in units of files, and then the models are divided according to their professions and stored in different node sub-clusters. Each sub-cluster maintains an independent sub-alliance chain, and the blockchain sub-network is responsible for processing intermediate drawing models generated by professional collaborative design. The upper main chain is responsible for model data exchange between sub-networks, and is responsible for processing and transmitting final version drawing models generated by all professional cooperation after being audited, so that the hierarchical alliance multi-chain form is used to overcome the problems of low BIM data storage efficiency and poor privacy in traditional single blockchains.

The utility model discloses a kind of cylinder core temporary storage devices suitable for cigarette machine auxiliary material, it is related to tobacco processing equipment technical field.The device includes base, center support component and outer peripheral limiting structure, the center support component is vertically arranged in the center position of base, for supporting tipping paper cylinder core;The outer peripheral limiting structure is arranged in the periphery of the center support component, and is fixedly connected with base, for limiting the outer sleeve space of cigarette paper cylinder core.The inside storage area formed between the center support component and the outer peripheral limiting structure is used for the sleeving stacking of tipping paper cylinder core, and the outside area of the outer peripheral limiting structure is used for the annular sleeving of cigarette paper cylinder core.The device is simple in structure, clear in classification, can realize intensive classified storage of different specifications cigarette auxiliary material cylinder core, improve on-site space utilization efficiency, reduce management cost, facilitate subsequent centralized recovery and processing, with good applicability and popularization value.

The invention discloses a data center data cold storage system, which relates to the technical field of data center storage management, and comprises the following steps: S1, constructing a data center cold storage object set; s2, performing object structured mapping by using the cold storage object set; s3, medium association construction is carried out by using the cold storage object identification structure; s4, performing system consistency constraint by using a cold storage medium association unit; and S5, carrying out system capability solidification by using the cold storage medium association unit and the cold storage system association state. By setting the object structured mapping based on the cold storage object set, each cold storage object can be subjected to unified coding and structured management in logic and physical levels. Specifically, logic numbers, physical storage positions, medium types and association relationships among objects of the cold storage objects are mapped into a uniform identification structure, so that the system can clearly identify the storage state of each object and the position of each object in the whole cold storage network.
