Title:
SELF-DIAGNOSIS METHOD AND NON-NEGATIVE PRESSURE ADDITIVE PRESSURE WATER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/098372
Kind Code:
A1
Abstract:
The present application provides a self-diagnosis method and a non-negative-pressure additive pressure water supply device. The method comprises: obtaining measurement data of a plurality of operation parameters of the non-negative-pressure additive pressure water supply device; upon detection that the measurement data of at least one of the operation parameters is not in a preset range corresponding to the operation parameter, taking the measurement data of the plurality of operation parameters as a first input of a fault detection model, and outputting a predicted fault type and a predicted similarity corresponding to the first input; and when the predicted similarity corresponding to the first input is less than a preset similarity threshold, determining that no fault occurs, and when the predicted similarity corresponding to the first input is not less than the preset similarity threshold, determining that a fault occurs. Whether a fault occurs is determined by using a two-stage detection process, where upon detection, in a first stage, that a fault possibly occurs, the occurrence of the fault is not directly determined, instead, fault detection of a second stage is performed, such that mis-determination is avoided.
