In response to the requirements for in-situ synchronous measurement and wireless data transmission of temperature parameters of rotating components,wireless power transmission technology and space optical communication technology were stu-died,and an 8-channel small-scale temperature parameter telemetry system was designed.The system achieved high-precision and accurate measurement of 8 temperature parameters through thermocouples and platinum resistor sensors,and synchronously wire-less transmitted electrical energy and collected data through electromagnetic induction and infrared light communication technolo-gy.The system analysis software completed real-time storage,parsing,and visualization of data.A simulated rotating environment testing platform with a speed of 20 000 r/min was built to verify system functionality and performance.The temperature acquisi-tion accuracy of the system is better than 0.15%,the wireless transmission distance is 15 mm,electric energy transmission peak power can reach 5 V/400 mA,the measured communication rate is 10 Mbit/s,and the 8-channel synchronous sampling rate is 56 kHz.The system achieves distributed and high-precision acquisition of temperature parameters,providing accurate temperature basis for the development and maintenance of rotating components.
