Research on high-speed torque measurement system based on FPGA
In response to the issue of accurately detecting torque on transmission shaft platforms rotating at high speeds,a torsional deformation-based torque measurement system designed for high-speed operational environments was introduced.The system comprises three main components:Hall sensors,Field Programmable Gate Array(FPGA),and an upper computer.Belonging to the phase difference torque measurement instrument category,this torque measurement system acquires deformation signals from the shaft and utilizes the FPGA as a processing chip to achieve accurate and efficient information processing.Additionally,an interactive interface based on PYQT5 was designed to display the final torque measurement results.Under high-speed rotating conditions,this system could effectively and precisely read the torque applied to the shaft at the current speed.Experimental results demonstrated that the proposed torque measurement system maintained a measurement accuracy error of within 1%for transmitted shaft torque,meeting the requirements of practical engineering measurements.
