为了突破传统Fe-Ni磁致伸缩材料测量量程的限制，采用了一种新型的Fe83 Ga17材料。讨论了传统硬件比较电路方法，为了解决硬件比较电路存在的问题，设计了基于数字信号处理器（ DSP）的磁致伸缩位移传感器信号处理系统，包括A/D采样模块、FIR滤波模块和位移测量模块。考虑到环境因素带来的误差，进行温度补偿设计，修正了测量结果。实验结果显示：基于DSP的信号系统能够达到较高的测量精度，对磁致伸缩位移传感器的实际应用有积极的意义。

In order to break through the limitation of measurement range of traditional Fe-Ni magnetostrictive material adopt a new kind of Fe83 Ga17 material,traditional hardware comparison circuit method is discussed. The digital signal processor( DSP)-based signal processing system for magnetostrictive displacement sensor,includes A/D sampling module,FIR filtering module and displacement measurement module is designed in order to handle the problems of the hardware comparison circuit. Considering the error caused by the environmental factor, temperature compensation is designed,measurement result is corrected. The experimental results show that the proposed system can achieve high measurement precision,it has a positive meaning in practical applications for magnetostrictive displacement sensor.
