Abstract
A pressure signal fitting method comprises applying a pressure to each sensing point in a pressure sensor, measuring and integrating a relationship between the pressure and a resistance of each sensing point to obtain a pressure-resistance relationship; correcting the pressure-resistance relationship through a numerical filtering algorithm, and fitting the corrected pressure-resistance relationship to obtain an optimized pressure-resistance relationship; switching sensing points of a voltage sensing circuit to measure voltages of a plurality of arrayed sensing points pressurized; calculating resistances of the plurality of arrayed sensing points according to the measured voltages; calculating pressures of the plurality of arrayed sensing points through the optimized pressure-resistance relationship; and based on areas of pressure zones and non-pressure zones of the plurality of sensing points, calculating actual pressures of the plurality of arrayed sensing points from the calculated pressures thereof.
