This invention relates to the field of aluminum foil performance testing technology, and discloses a performance testing system for hydrophilic aluminum foil used in air conditioning heat dissipation, including a data acquisition module and an intelligent testing module. The system acquires stamping management data, operating condition simulation data, and application testing data of all aluminum foil samples through the data acquisition module, and classifies them into datasets. The intelligent testing module evaluates the distortion degree of each aluminum foil sample after stamping, generates a distortion index, and provides accurate basis for service reliability. The multi-dimensional testing has high accuracy. The intelligent testing module evaluates the performance quality of each aluminum foil sample under simulated operating conditions, generates a performance index, eliminates the limitations of single indicators, and achieves comprehensive characterization of core properties such as hydrophilicity and corrosion resistance. It analyzes the uniformity of application performance of each aluminum foil sample, generates an application index, accurately quantifies the uniformity of coating thickness and roughness, sets fixed thresholds, and outputs corresponding evaluation and management suggestions, demonstrating strong adaptability for hierarchical management.

This application provides a method and apparatus for adjusting the noise shielding window of an ultrasonic flow meter. The method includes: obtaining the spacing for the current measurement based on the echo signal of the current measurement; wherein the spacing is the distance between the sampling start point and the characteristic position of the sampling signal; if there is a difference between the spacing in the current measurement and the spacing in the previous measurement, then based on the difference, adjusting the noise shielding window of the previous measurement to obtain the noise shielding window for the current measurement; and if there is no difference between the spacing in the current measurement and the spacing in the previous measurement, then using the noise shielding window of the previous measurement as the noise shielding window for the current measurement; and performing the current ultrasonic flow measurement according to the noise shielding window of the current measurement. By adjusting the noise shielding window in real time, the time period of the effective signal is limited, avoiding the distortion caused by noise interference at the front end of the effective signal, and reducing the error caused by noise in fluid flow detection.
