摘要
针对飞机发动机专用测振仪器的缺点,设计出基于单片机MSP430F133的振动测量仪,详细介绍了它的测量原理及软、硬件设计。该测振仪采用16位AD转换芯片ADS7809进行A/D转换,并在软件上针对传感器的频率响应对测量结果进行补偿,将部分硬件功能软件化,简化电路,减小仪器调试的难度,保证仪器的精度。
The article refers the principle of the vibration meter based on MSP430F 133 and also introduces its hardware and software designs. This apparatus uses ADS7809 which is the 16-bit sampling A/D converter to complete A/D conversion. The frequency responses of sensor also have been compensated in the software design. The circuits of the vibration measuring meter are simplified greatly and this also makes the instrument＇s debugging more convenient.
