Abstract

Aiming at the output characteristic of fiber optics liquid-level sensor

the software method of high precision data processing is studied base on digital signal processor（DSP）.A method of real-time data processing which combining rejecting the mistake error

digital filtering and nonlinear fitting is presented

the photoelectric converter adopting TMS320C6711 is designed

the software flowchart is given also.The experiment shows that this method not only simplifies design

improves measurement precision and generality of sensor

but also is suitable for the application.
