Title:
FAULT DETECTION METHOD AND SYSTEM FOR WATER CHILLING UNIT, AND WATER CHILLING UNIT
Document Type and Number:
WIPO Patent Application WO/2021/008176
Kind Code:
A1
Abstract:
A fault detection method and system for a water chilling unit, and a water chilling unit. The fault detection method for a water chilling unit comprises: obtaining fault operation data of a water chilling unit (S101); oversampling the fault operation data to obtain fault missing data (S102); establishing a fault characteristic parameter prediction model according to the fault operation data and the fault missing data (S103); and determining, according to the fault characteristic parameter prediction model, whether operation data of the water chilling unit is abnormal (S104). The fault detection method for the water chilling unit has an advantage of accurate and reliable detection. In addition, the occupation of the detection on resources can be effectively reduced, so that the implementation of the fault detection method in the water chilling unit is facilitated, and the reliability of the water chilling unit is improved.
