System and method for structure health monitoring based on block chain technology and smart contract

Abstract

The invention provides a system and a method for structural health monitoring based on a block chain technology and a smart contract. The system comprises a data acquisition module, a data temporary storage and transmission module, a data analysis module and an intelligent monitoring module; the data acquisition module comprises a sensor and a digital camera which are arranged on a building structure, and the sensor and the digital camera are used for acquiring original data; the data temporary storage and transmission module comprises a local gateway, and the local gateway is in wireless connection with the data acquisition module and the data analysis module; and the data analysis module comprises a block chain network system and the health monitoring smart contract deployed in the blockchain network system. The information among the participants is accurate, efficient and shared, and the operation efficiency of the whole system is improved from the perspective of data management and application. The structure health monitoring system is effectively prevented from being paralyzed under the condition of a server fault or a network fault.

Description

technical field [0001] The present invention relates to the technical field of civil engineering structural health monitoring, and more specifically, to a structural health monitoring system and method based on blockchain technology and smart contracts. Background technique [0002] Since the construction of the engineering structure, with the increase of service time, it has been continuously affected by environmental erosion, various loads and natural disasters. Without proper maintenance, the state of civil engineering infrastructure will gradually deteriorate and become unhealthy. reliable. Structural health monitoring of civil engineering structures refers to the use of on-site non-destructive sensing technology to achieve the purpose of detecting structural damage or degradation through the analysis of structural system characteristics including structural response. [0003] However, the current monitoring systems are all developed based on a centralized architecture,...

AI Technical Summary

Problems solved by technology

[0003] However, the current monitoring systems are all developed based on a centralized architecture, which is prone to data security risks and network bottlenecks

Modern health monitoring projects often require the participation and cooperation of multiple parties such as the monitoring team, maintenance team, management, and customer groups, resulting in low efficiency of information sharing and multi-party cooperation in existing health monitoring methods, which in turn leads to low efficiency of the entire monitoring project

Moreover, traditional structural health monitoring adopts a centralized server solution. Whether it is cloud computing or the Internet of Things, once a server failure or network failure occurs, it may cause irreparable and serious consequences.

[0004] Therefore, there is an urgent need in the prior art for a technical solution that can effectively solve the problems of data insecurity, network bottlenecks, and low decision-making efficiency in existing methods in building structural health monitoring.
