Structural Smart Sensors for LIVE Digital Twins of pipelines in Power Generation and Oil and Gas Industries (3S for LIVE Digital Twins)

一些结构性资产（如石油和天然气或发电行业的管道结构）的失效可能是非常昂贵的，危险的，并且对环境有害。有一个准确可靠的维护计划是非常重要的，以避免故障的发生。该项目的目标是开发一种诊断传感器，用于在线智能测量工作结构的各种健康监测相关参数，特别是石油和天然气或发电行业的管道。这种传感器在这里被称为结构智能传感器（3S），因为它们能够(i)从大量收集的原始数据中产生高质量的信息，（ii）与其他机器和物联网（IoT）平台通信，（iii）调整检查频率，传输调度和处理参数，智能地使用它们自己产生的信息。3S可以直接用于LIVE数字孪生（DT）平台，具有本提案中描述的特性。3S专门收集结构系统的振动数据，对数据进行处理，生成系统健康状况信息，并根据LIVE数字孪生系统中的预定义模型确定失效概率。当无数传感器需要收集大量原始数据时，它对DT应用非常有益，这些数据几乎不可能在多年的服务中动态传输。所述智能传感器是一个将物理感知机制和网络组件相结合的网络-物理微系统，根据经过验证的预定义模型处理收集到的数据。采用抽象的仿真公式动态完成现场处理，得到高质量的数据，在计算时间和传输频率方面降低了处理成本。考虑到第四次工业革命的要求以及工业向数字化和机器智能化发展的重大需求，在不久的将来，3S将是至关重要的，在加拿大拥有这项技术将提高加拿大在国际市场上的竞争力。

Failure of some structural assets such as the pipeline structures in oil and gas or power generation industries can be extremely expensive, hazardous, and dangerous to the environment. It is highly desired to have an accurate and reliable maintenance plan to avoid the failure. The goal of this project is to develop a diagnostic sensor for on-line smart measurements in various health monitoring- related parameters of a working structure, particularly the pipelines in oil and gas or power generation industries. This sensor is referred as Structural Smart Sensors (3S) here due to their capabilities in (i) producing high quality information from a significant volume of their collected raw data, (ii) communicating to other machines and in an Internet of Things (IoT) platform, (iii) adjusting their inspection frequency, transmission scheduling, and processing parameters, smartly using the information they produce themselves. 3S can be used directly in a LIVE Digital Twin (DT) platform with the characteristics described in this proposal. 3S specifically collects the vibrational data of the structural system, processes the data to produce the information regarding the health of the system, and determines the failure probabilities according to the predefined models in the LIVE digital twin system. It is highly beneficial for DT applications when a myriad number of sensors need to collect high volume of raw data which are almost impossible to be transmitted dynamically over the years of service. The described smart sensor is a cyber-physical micro-system with a combination of physical sensing mechanism and cyber component to process the collected data based on the validated predefined models. It dynamically completes on-site processing using the abstract simulation formula and produces high quality data which results in low processing cost in term of computational time and transmission frequency. Considering the requirements of the 4th industrial revolution and the significant needs of industries to move toward digitalization, and intelligence of machines, 3S will be vitally needed in a very near future and having this technology available in Canada will increase Canada's competency in the international markets.
