Title:
WATER COOLING SYSTEM LEAKAGE MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/240821
Kind Code:
A1
Abstract:
A water cooling system leakage monitoring method, comprising: acquiring liquid level value change data, and constructing a scale function; decomposing the liquid level value change data into low-order high-frequency components and low-order low-frequency components by using a wavelet transform; reconstructing a high-order scale function by using the low-order low-frequency components; obtaining a liquid level change trend curve according to the high-order scale function, and monitoring, according to the liquid level change trend curve, whether leakage occurs. By means of a wavelet transform method, liquid level fluctuations caused by temperature can be filtered so as to obtain liquid level change trend data, so that the leakage of a valve cooling system can be effectively and accurately determined, defects of valve cooling monitoring means in the prior art can be overcome, and the stability of the valve cooling system is improved.
