Aiming at problems that torque measurement of large vehicle load spectrum need to be carried out in challenge of high rotation speed

large range of torque and temperature and smeary environment

wireless Zig Bee-based torque measurement device for rotating shaft is set up.Strain gauge is used as sensitive element and measuring device are mounted to rotating shaft and wirelessly send measured datas to receiver device fixed on internal wall of the closed system and transmit to computer through serial port.Experimental analysis show that the measurement equipment works well in high sampling frequency and complicated environment.The measurement scheme is verified feasible and reliable.It is adequate for high-speed rotation non-contact and low power consumption torque measurement.
