Abstract

A system may include temperature sensors configured to measure temperatures of devices within an industrial automation system. The devices may be disposed within enclosures separate from one or more spaces of an ambient space of the industrial automation system. The system may include thermal image sensors configured to acquire thermal imagery data associated with the ambient space. The system may include a processor configured to receive a first set of temperature data acquired by the temperature sensors over a period of time. The processor may further generate a second set of temperature data representative of one or more predicted temperatures associated with one or more additional spaces of the ambient space. The temperature model may represent expected temperatures of the one or more spaces with respect to the temperatures within the enclosures. The processor may generate a heat map visualization including one or more thermal indicators representative of the predicted temperatures.
