說明書
The present disclosure relates to a self-contained hydrogen power system for a smart farm.
As the era of the fourth industrial revolution elapses and IT technologies are converged regardless of the type of business, a farm is also developed into a smart farm. As the population of seaside towns is reduced and aging continues, at timing at which earnings are stalled, a movement to increase fishery productivity through the convergence of IT technologies in various fields is actively started, and thus the smart farm is activated. The smart farm can increase efficiency and convenience of production because a growing environment for aquatic products can be properly maintained and managed through the construction and operation of an integrated monitoring system using a smartphone application or a PC and the system can be remotely managed. However, with the development of the smart farm, power consumption is increased and it is difficult to supply power adrift. Accordingly, there is a need for a technology capable of producing energy eco-friendly and independently.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
