AI Technical Summary
Existing demagnetizing switch testing systems suffer from problems such as dispersed equipment, cumbersome operation, weak anti-interference capability, low synchronization accuracy, and insufficient automation, making it difficult to achieve high-precision contact resistance testing and action timing testing.
An intelligent integrated testing method for demagnetizing switches is adopted. By integrating the FPGA hardware execution layer, intelligent algorithm layer and application interaction layer, the method realizes the integration of automatic contact resistance testing and action timing testing. Combined with adaptive Kalman filtering, multi-dimensional feature extraction and confidence weighted fusion, the measurement accuracy and synchronization accuracy are improved.
It enables high-precision contact resistance and action timing testing in environments with strong electromagnetic interference, improving measurement accuracy from milliseconds to microseconds. The testing process is automated, reducing human error and increasing testing efficiency.
