Latest Patents

Miao is credited with 1 patent: “Method and Device for Testing Positioning and Speed Measuring System Main Unit.” The invention simulates signals from absolute and relative position sensors and sends them to the system’s main unit. It then compares the result calculated by the main unit with a reference result based on the same simulated signal. If the difference exceeds a preset range, the main unit is determined to be abnormal.

This approach allows the main unit to be tested without using physical absolute and relative position sensors. It is designed to simplify testing and make it possible to establish a test environment without substantial investment in large-scale equipment.

Career Highlights

Miao’s listed patent reflects work on testing methods for positioning and speed measurement systems. Her association with CRRC Qingdao Sifang Co., Ltd. connects her patent activity with a company in the rail transportation sector.
