Intelligent Fault Diagnosis for Laboratory Equipment
ABSTRACT Traditional laboratory management relies heavily on manual oversight and static threshold‐based fault diagnostics, which are inadequate for addressing the dynamic, individualised needs of contemporary environments. To address these challenges, we proposed an intelligent laboratory management framework, designed to enable secure and autonomous ...
