Title:
METHOD AND SYSTEM OF SENSOR FAULT MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2022/165792
Kind Code:
A1
Abstract:
A method and a system of sensor fault management for a chiller plant is disclosed. The method comprises the steps of: obtaining (S310) a fault-free dataset of sensors for the chiller plant; generating (S320) a faulty dataset by introducing instantaneous sensor signal errors into the fault-free dataset; running (S330) a system model with the fault-free dataset and the faulty dataset as inputs to obtain a modeled dataset, wherein the system model is set up by deep learning with operating parameters and the fault-free dataset; building up (S340) a fault pattern database including fault-free profiles and faulty profiles based on the modeled dataset; evaluating and reconstructing (S350) sensor data for evaluation with reference to the fault pattern database. This is a smart sensor fault detection and diagnosis solution through big data analytics and it is applicable for multiple sensors for various chiller plants.
