Blockchain can ensure data security and reliability during the stage of building operation maintenance (BOM), provide reliable for decision-making. However, existing schemes based on single-chain architecture have problems storage limitation scalability, ignore impact event's priority real-time blockchain transaction. Therefore, BOM, this paper provides a BOM framework sharding (SBC-BOMF), which constructs two-layer master-chain multiple shards, relieves pressure nodes improves concurrency...
Sharding technology can address the throughput and scalability limitations that arise when single-chain blockchain are applied in Internet of Things (IoT). However, existing sharding solutions focus on addressing issues like malicious nodes clustering cross-shard transactions. Existing cannot adapt to performance disparities edge characteristic three-dimensional data queries building IoT. This leads problems such as shard overheating inefficient query efficiency. paper proposes a dual-layer...
The existing multi-person collaborative design scheme of Building Information Modeling (BIM) integrated with blockchain faces problems such as poor reliability BIM drawing, inconsistent drawing information, redundant and inaccurate protection copyright interests. This paper proposes a model for that combines InterPlanetary File System (IPFS). uses to store information protect the interests designers IPFS ensure drawing. A cycle division mechanism is designed solve problem synchronization...
<abstract><p>Community governance is the basic unit of social governance, and it also an important direction for building a pattern co-construction, co-governance sharing. Previous studies have solved problems data security, information traceability participant enthusiasm in process community digital by system based on blockchain technology incentive mechanisms. The application can solve low difficulty sharing tracing part multiple subjects regarding participation governance....
With the globalization of manufacturing industry, there is an increasing need for tools to capture, represent, and exchange product development knowledge. Collaborative engineering design has emerged support distributed collaborative development. Product process nowadays featured with workflow, complicated interaction intensive collaboration. In order shorten lifecycle, integration CAE functionalities environment necessary. However, due complex nature life cycle management (PLM) such may...
The forest fires are caused by extremely complex natural factors and human factors. How to convert from passive prevention taxed a lot of manpower material resources into the active management model with automatic monitoring alarming, it has been technical problem for department. In digital video surveillance system, we used image recognition technology track suspicious moving target alarm in period fire prevention, recognize monitoring. We selected two places do some test Laoshan system...

The collaborative construction method of knowledge graph based on blockchain is crucial for the safe and efficient Biomedical Knowledge Graph (BioKG), has received widespread attention from academic medical circles. At present, data sources are very wide. While using multi-source to collaboratively build a graph, redundancy problems often occur. Once large number available, it becomes difficult system ensure consistency in reliable way. In addition, increase inconsistent redundant also...
As an important part of digital building, building internet things (BIoT) plays a positive role in promoting the construction smart cities. Existing schemes utilize blockchain to achieve trusted data storage BIoT. However, full-copy mechanism and management requirements massive have brought computing challenges edge nodes with limited resources. Therefore, scheme for BIoT based on sharding is proposed. The proposes hybrid mechanism, which uses inter-planetary file system (IPFS) ensure...
Regarding the issues of shard overheating and low efficiency three-dimensional data queries caused by application blockchain sharding technology in Building Internet Things (BIoT). Therefore, a management method based on DAG has been proposed. Firstly, an adaptive balancing load algorithm is designed to periodically network, dividing nodes according their values interaction characteristics avoid problem aggregation low-load nodes. Secondly, S-DAG dual-layer architecture, which combines...
