Precision dairy edge, albeit analytics driven: A framework to incorporate prognostics and auto correction capabilities for dairy IoT sensors

Abstract

Oxford English Dictionary defines Prognostics as “an advance indication of a future event, an omen”. Generally, it is confined to fortune or future foretellers, more have subjective or intuition driven. Data Science, on the other hand, embryonically enables to model and predict the health condition of a system and/or its components, based upon current and historical system generated data or status. The chief goal of prognostics is precise estimation of Remaining Useful Life (RUL) of equipment or device. Through our research and through industrial field deployment of our Dairy IoT Sensors, we emphatically conclude that Prognostics is a vital marker in the lifecycle of a device that can be deduced as inflection point to trigger auto-corrective, albeit edge analytics driven, in Dairy IoT Sensors so that the desired ship setting functions can be achieved with precision. Having auto-corrective capability, importantly, plays pivotal role in achieving satisfaction of Dairy farmers and reducing the cost of maintaining the Dairy sensors to the manufacturers as these sensors are deployed in geographically different regions with intermittent or network connectivity. Through this paper, we propose an inventive, albeit, small footprint, ML (Machine Learning) dairy edge that incorporates supervised and unsupervised models to detect prognostics conditions so as to infuse auto-corrective behavior to improve the precision of dairy edge. The paper presents industrial dairy sensor design and deployment as well as its data collection and certain field experimental results.
