Title: Dongyu Zhao: Inventor of a Positioning and Speed-Measurement Testing Method
Introduction
Dongyu Zhao is an inventor based in Qingdao, China. His work includes a patented method and device for testing the main unit of a positioning and speed-measuring system.
Latest Patents
Zhao is associated with 1 patent, titled “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 unit with a reference result for 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 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.
