摘要
利用光纤光栅中心反射波长受应力变化灵敏度高、线性好的特性,构建了一种新型大范围、高灵敏度的测重系统.利用A/D转换芯片与单片机的接口技术将系统前端输出的模拟信号转化成数字信号,再用单片机编程实现应力的线性转换,还原出前端重力,给出了相应的算法和源程序代码.
Based on the properties such as fiber grating centre reflection wavelength stress high sensitivity and good linearity, a new large-scale and high-sensitivity measurement system is built. The output analog signals of front-end is converted into digital signals by using A/D converter chip and microcontroller interface technology and then stress linear conversion in implemented by MCU program to reduce the front of gravity and give the corresponding algorithms and source code.
