Capacitance sensing detecting method for emergency stopping of moving part, processor for approaching or touching detection, and system thereof

Abstract

A capacitance sensing detecting method for emergency stopping of moving part, which is applicable to a capacitance sensing processor for detecting approaching or touching object, wherein the method comprising: providing driving signals to a driving electrode and sensing the driving signals induced by a sensing electrode for detecting an external conductive object approaching or touching a protection shield of the moving part, wherein a first capacitor is formed between the protection shield and the driving electrode, a second capacitor is formed between the protection shield and the sensing electrode; determining signal strength of the sensed driving signals; and notifying a controller of the moving part to stop the moving part when the signal strength of the driving signals exceeds a threshold.
