The Design of Ship Shaft Power Measuring System Based on Inductive Power Supply and 2.4GHz Wireless Data Transmission

This system is designed to solve the wireless inductive power supply, the high precision torque measurement, and the reliability wireless data transmission in ship shaft power measurement. In order to realize the high-precision torque measurement, the system adopts 24-bit high-precision and low-noise AD conversion chip CS5532. At the same time, in order to ensure the real-time and reliability wireless data transmission, the system use 2.4GHz wireless data transmission technology. The system calibration accuracy was verified by the torque calibration test on the 50 kNm (U = 0.05%, k = 3) standard machine in Shanghai Marine Equipment Research Institute Torque Calibration/Test Laboratory. The tests shows that the system meets the design requirements and meets the requirements of ship shaft power measurement.
