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
