Patent attributes
A sensing and alert system is installed in a plurality of electrical switchgear cabinets. Each switchgear cabinet includes at least one high-voltage circuit breaker, and each switchgear cabinet is in communication with a central programmable logic controller (PLC) configured to activate and deactivate the high-voltage circuit breaker in the corresponding switchgear cabinet. The sensing and alert system includes a time of flight (ToF) sensor arranged to capture real-time image data, a lighting module affixed to an inside portion of the switchgear cabinet, and a processor operatively coupled to the ToF sensor and to the lighting module. The sensing and alert system is affixed to an inside portion of each switchgear cabinet. The processor compares real-time image data from the ToF sensor to the stored calibration image data and transmits an alarm if the difference is greater than a predetermined amount.
