SUN Gui-rong, WANG Jun, LI Hui-peng, et al. Research on signal acquisition system for inductive sensor based on USB[J]. 2008, (2): 56-58. DOI: 10.13873/j.1000-97872008.02.029.
An inductive sensor signal acquisition system based on USB interface is introduced.It takes the inductive sensor as the sensing component
and the P89C61 single chip micro-processor as the core
and data communication is realized by USB interface.The construction and working principle for the system are introduced.The measuring circuit of inductive sensor
USB interface circuit and software design are presented in detailed.The firmware of the system is written by KeilC51 language and the USB driver and application by VC++.Experiment results show that measuring accuracy of the system may be 0.01μm in the range of ±10μm.The system has stable performance
good effect and good convenience when it is used in data acquisition of surface roughness and roundness measurement signals and so on.
