Process/Equipment performance management is considered to be a challenging task because processes we aredealing with are mostly dynamic, nonlinear in nature and interconnected. Incipient changes in relationshipbetween underlying variables are not easy to detect and identify through simple process data trending. For asystem/process, fault detection and diagnosis (FDD) should be done at different levels (e.g. sensor level,equipment level, unit level, etc.), since at each level the information and resources available for conductingFDD are different, and algorithms and design objectives of FDD are usually different too. Clearly for a trulyautonomous and intelligent health monitoring system, a metastrategy needs to be developed to integratedifferent design schemes based on specific design objectives at different asset hierarchy. Furthermore,application of data driven FDD at both equipment and unit-level is deemed novel. In this Engage Plus Grantproject, we aim to work closely with Honeywell Process Solutions to investigate and develop an innovativedata-driven fault detection and diagnosis framework by applying a hierarchical deep learning approach.

过程/设备的性能管理被认为是一项具有挑战性的任务，因为我们所处理的过程大多是动态的、非线性的、相互关联的。通过简单的过程数据趋势分析，不容易检测和识别潜在变量之间关系的早期变化。对于系统/过程，故障检测和诊断(FDD)应该在不同的级别(如传感器级别、设备级别、单元级别等)进行，因为在每个级别上可用于进行FDD的信息和资源不同，FDD的算法和设计目标通常也不同。显然，对于一个真正自主和智能的健康监测系统，需要开发一个元战略，以在不同的资产层次上基于特定的设计目标整合不同的设计方案。此外，数据驱动软驱在设备级和机组级的应用都被认为是新颖的。在这个Engage Plus Grant项目中，我们的目标是与Honeywell Process Solutions密切合作，通过应用分层深度学习方法，研究和开发创新的数据驱动的故障检测和诊断框架。
