Title: Daofu Hu: Innovator in Magnetic Levitation Technology
Introduction
Daofu Hu is a prominent inventor based in Zhuhai, China, known for his contributions to magnetic levitation technology. With a total of 7 patents to his name, he has made significant advancements in the field of displacement sensors and correction systems.
Latest Patents
One of his latest patents is a fault processing system for displacement sensors. This innovative method involves receiving multiple detected signals from various detecting probes and a given signal from a spare probe. The detecting probes are designed to measure the displacement value of a rotation shaft in a magnetic levitation motor. The system determines if any probes are faulty and connects the spare probe's signal to the faulty one when necessary.
Another notable patent is a displacement correction apparatus, which includes a reference circuit and a correction circuit. The reference circuit provides a reference signal, while the correction circuit performs a logarithm operation on a nonlinear displacement signal to produce a corrected linear displacement signal. This apparatus addresses the issue of poor detection accuracy caused by the non-linear relationship between the position signal from an eddy current sensor and the displacement signal of a shaft.
