The rapid development of blockchain technology is exerting a profound impact on all walks of life. Blockchain, which is a decentralized and distributed technology architecture, has inspired people to think about the social development model. However, blockchain technology has not been applied to health monitoring. Therefore, this study proposes a distributed health monitoring system based on blockchain technology, which realizes data security, information transparency, efficient sharing, and independent decision making with smart contracts. First, the system is designed as a blockchain network for structural health monitoring (SHM), and a series of smart contracts for health monitoring is developed to achieve monitoring authority verification, structural damage identification, and other functions. Based on the strength of the Ethereum private chain and Guangzhou New TV Tower benchmark model, smart contracts for health monitoring were deployed, and a series of tests of the proposed system were performed. The results indicate that the proposed system can provide monitoring authority verification, generate abnormal alerts, immutability of data, attack resistance, and traceability query.

土木结构健康监测系统的区块链技术与智能合约

区块链技术的快速发展正在对各行各业产生深远的影响。区块链作为一种去中心化、分布式的技术架构，激发了人们对社会发展模式的思考。然而，区块链技术尚未应用于健康监测。因此，本研究提出了一种基于区块链技术的分布式健康监测系统，通过智能合约实现数据安全、信息透明、高效共享和自主决策。首先，将系统设计为结构健康监测（SHM）区块链网络，开发一系列健康监测智能合约，实现监测权限验证、结构损伤识别等功能。基于以太坊私有链和广州新电视塔基准模型的优势，部署了健康监测智能合约，并对提出的系统进行了一系列测试。结果表明，所提出的系统可以提供监控权限验证、异常警报生成、数据不变性、抗攻击性和可追溯性查询。
