Abstract
The disclosure provides a pressure sensing signal processing method and system thereof. The pressure sensing signal processing method includes the below steps: acquiring the resistance; first-order differentiation on the recorded resistance-time curve and acquiring the corresponding slope value; matching the slope value with at least one predetermined database to acquire a pressing force gradient corresponding to the slope value; calculating and acquiring a pressing force based on the pressing force gradient. The system includes resistance detection module, differentiation processing module, comparison reference module and calculation module.
