A thermal monitoring system includes thermal monitoring devices that generate sensor data including thermal images depicting monitored elements (e.g. of an electrical switchgear system). The sensor data for all monitoring devices installed at a local deployment is collected by a gateway device, and relevant data from multiple local deployments is further aggregated by a cloud management system for further analysis. New event triggering rules determining how the thermal monitoring devices filter or record the sensor data are generated based on the aggregated data during a continuous learning process. The system detects patterns in the sensor data for the monitoring devices and/or local deployments as a whole and tracks deviations from these patterns, improving the accuracy of the event detection over time.

Universal programmable optic/acoustic signaling device with self-diagnosis
A signaling system includes a universal, programmable, and customizable signaling device. The signaling device includes light indicators, such as a colored light-emitting diode (LED) screen with pixels distributed on an indicating surface of the device facing all directions. A segmented assembly with driver, light, sound, and diagnostic sections allows customization of the device to accommodate different size requirements in different contexts. The signaling device includes both analog and digital inputs for receiving control signals from a monitored system, as well as additional inputs for receiving signaling instructions from a configuration device. Based on the signaling instructions and the control signals, the signaling device presents status information for the monitored system via programmed audible and visual alarms and signaling patterns, including animations. Diagnostic monitors of the signaling device determine a diagnostic status for the device, and a diagnostic indicator presents diagnostic information to ensure that the signaling device is operating normally.

A safety system for high-voltage electrical cabinetry presents alarm indications representing alarm conditions of the electrical switchgear cabinet system at every electrical switchgear cabinet during maintenance. The system includes encoder and decoder devices connected to existing switchgear cabinet lighting infrastructure. The encoder devices receive alarm signals from a control system of the electrical switchgear cabinet system and send encoded alarm signals to the decoder devices by modulating power relayed from the encoder devices to the decoder devices and possibly to lamps. The decoder devices decode the encoded alarm signals and present the alarm indications audibly and/or visually using light and sound indicators. A technician performing maintenance can evaluate instantly the importance of the alarm based on the alarm indications and act accordingly.

High voltage safety system and method for electrical cabinetry
A safety system for high-voltage electrical cabinetry provides active visual and/or audible warnings during maintenance. Load monitors evaluate electrical loads of dedicated power circuits used by an existing automatic lighting system. Light and sound indicators present status information (e.g. indicating maintenance status or normal operating status) to persons in signaling areas based on whether the evaluated electrical loads indicate that at least one lamp is turned on. A common power supply can be used to power the lighting circuit and the indicators. Bridge modules can also be used to monitor the electrical load for different group lighting circuits and report discrete group status information to a programmable logic controller while also sharing the group status information with the other bridge modules. In this case, the indicators present combined status information, for example, indicating a maintenance status if any lamps from any group is turned on.

Sensing and alert system for electrical switchgear
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.
