摘　　要：主要介绍了应变电阻式张力传感器结构原理,重点针对当今在微小力传感器设计开发过程中遇到的温漂、时漂、噪声干扰等问题,提出了通过软件进行机器学习、数字滤波等技术的原理。设计开发了一种基于SPCE061A单片机和张力传感器的微小动态张力检测系统。通过最小二乘法实现对传感器的自动建模,用软件方法解决温漂问题并用数字滤波滤除干扰的尝试。在解决温漂问题上,引用了数据融合技术,将原本需要曲面拟合的问题转化成一个拟合过程和一个插值过程。This paper introduces the theory of the circuit configuration of resistance strain sensor for tension measuring.It focuses on the problems we have to face in small tension measuring,as drifting over time,drifting over temperature,noise.And gives some solutions about machine learning,digital filtering area. This design develop an instrument for measuring small tension based on SPCE061A microcontroller and tension transducer.The model of the sensor is developed by using least square regression method.The temperature-shifting problem is solved automatically through programming.This design also use digital filter to filter noise.A data fusion algorithm for sample set transforms surface problem into a curve fitting problem and a curve interpolation problem.
