Abstract
Systems and methods of monitoring the health of an emergency power source for a luminaire node that is a node of a wireless mesh network utilized by a process control system include: utilizing, by the luminaire node, mains power to (i) route process control messages utilized by the process control system via the wireless network to thereby control an industrial process, and (ii) energize an illumination source of the luminaire node and/or maintain communications with another luminaire; storing, by the luminaire node, energy in an energy storage device configured to perform these functions during a loss of mains power; monitoring, by the luminaire node, the energy storage device to determine a health status associated with the energy storage device; and sending, by the luminaire node, an indication of the health status associated with the energy storage device via the wireless mesh network utilized by the process control system.
