Abstract：Inertial MEMS devices require testing and calibration during the production,acceptance,and use stages.The most commonly used testing equipment is the turntable,but the accuracy of performance indicators such as angle and speed provided by traditional testing turntables is difficult to exceed that of similar performance indicators of the tested inertial devices.This article de-signs an upper computer software system for turntable control to address this issue.Using Visual Studio2017+QT5.12 as the upper computer software development platform,the software design is programmed by using VC++language under VS2017.The upper com-puter interface is built using UI controls and graphic design tools under the QT framework.To ensure real-time control,the RTX re-al-time operating system is adopted.The upper computer sends,receives,converts,and displays real-time control instructions for the turntable through the RS422 serial port.Tests show that the angular position error of the turntable control is less than 0.56%,and the angular velocity error is less than 0.23%.
