摘　　要：为解决高旋、高温等极端环境下旋转部件传感参数原位采集和实时传输的难题,研制了多通道传感参数遥测系统。系统包含转子组件、定子组件和可视化终端。转子组件通过空间光通信实现与定子组件的双向无线数据传输。转子组件圆周轴对称、叠层架构设计降低了高速惯性力的影响。通过搭建5 000 r/min转速的模拟旋转测试环境进行系统功能和性能验证,实现采集精度0.25%,无线传输距离50 cm,传输速率10 Mbit/s和128通道同步采样率5 kHz。该设计方案为旋转部件试验和优化设计提供稳定可靠的参数测量技术。To solve the challenges of in-situ acquisition and real-time transmission of sensing parameters for rotating compo-nents in extreme environments such as high rotation and high temperature,a multi-channel sensor parameter telemetry system was developed.The system comprises rotor component,stator component,and visualization terminal.Bidirectional wireless data trans-mission with the stator component was achieved via free spatial optical(FSO)communication.The circular axisymmetric laminat-ed structure design of the rotor component reduces the impact of high-speed inertial force.Building a simulated rotation testing en-vironment with a speed of 5000 r/min verified system functionality and performance.The acquisition accuracy of 0.25%,wireless transmission distance of 50 cm,transmission rate of 10 Mbit/s,and 128 channel synchronous sampling rate of 5 kHz were a-chieved.This design scheme provides a stable and reliable parameter measurement method for rotating component testing and op-timization design.
