CAPACITIVE WIRE SENSING FOR GUARDING APPLICATIONS

摘要

A system, method and device for capacitive sensing of a guarding application is provided. A capacitive sensing module is coupled to one or more features of a guard system having capacitive guard panels and protective grids. Based on a user contacting at least a portion of the guard system, a determined indication of contact and/or presence may trigger a corresponding response by the guard system via the capacitive sensing module. A baseline level of noise is calibrated over time to adjust for varying conditions that do not correspond to a triggered, user-detection measurement. Corresponding outputs are generated based on a type of detection information received and/or user identity associated with the received capacitance detection. A capacitive sensing module may be configured to receive one or more items of capacitance change data and determine an appropriate triggered response based on an amount of capacitance change and threshold detection duration.

1. A method for detecting presence with respect to a guard, the method comprising:
receiving information provided by at least one capacitive component associated with the guard; determining that a change in voltage satisfies a threshold amount; and based on determining that the threshold amount is satisfied, initiating a corresponding response.
