Patent ID: 11957087

Abstract:
An internet of things (IoT) based hydroponic farm system is described. The hydroponic farm system includes a cloud server, a plurality of hydroponic farms, and a plurality of user computing stations. The cloud server includes a data distribution service domain that includes data distribution service middleware configured to use a real-time publish-subscribe protocol to wirelessly communicate hydroponic farm information. Each of the hydroponic farms is divided into a plurality of hydroponic plant growing zones that are configured to grow at least one species of plant. Each hydroponic plant growing zone includes a zone controller. A farm controller is assigned to each of the hydroponic farms. The plurality of user computing stations are subscribed to the data distribution service middleware and are configured to communicate, through the data distribution service domain, with the zone controller, the farm controller, a process controller, a production planning controller, and an enterprise resource planning controller.
