US 2019/0159007 A1 · Control System With Smart Devices For Hazardous Environments

Abstract

A control system for hazardous environments decreases flame paths, decreases punctures to the control system when installing interfaces, and increases safety. The control system may be characterized as a “one size fits all” controller that is able to automatically recognize a plurality of user interfaces. The controller has an enclosure to which the interfaces can be attached. The interfaces may interact with control electronics wholly contained in the enclosure using a variety of “wireless” mechanisms. Such mechanisms include reflecting light waves, infrared (IR) communication, radio-frequency identification, inductive coils, short-range wireless communication, camera images, piezoelectricity, and magnetism, and the like. The interfaces may include switches, indicator lights, smoke detectors, and the like.
