| Abstract: | Aiming at the requirement of high-precision and non-contact displacement sensing in tower crane torque monitors,selecte Honeywell＇s HMC1501 magnetoresistive sensor to achieve accurate measurement of displacement.. The magnetoresistive sensor has a small size, high precision, anti-interference ability, can achieve non-contact measurement. and the BP neural network is used to compensate the nonlinear of magnetoresistive sensor＇ s output. It improves the system＇s accuracy,reliability,and reduces costs. |
