Abstract
Abstract In this paper, we propose human detection and fuzzy temperature control system for energy reduction of cooling device in elevator. In order to improve problems of existing co oling device using the refrigerant, energy reduc-tion and efficient management are continuously achieved because of operation of thermoelectric cooling device using the human detection and fuzzy temperature control system. The proposed system confirms the number o fpassengers in elevator and temperature is then controlled by th ose numbers and an average temperature for the season in fuzzy system. The human detection method scans the nu mber of passengers using a head part as a feature based on bird's-eye view camera in elevator. The fuzzy system determines elevator internal temperature considering atmospheric temperature and the scanned passenger n umbers as a look-up table. The proposed sys-tem reduces energy of the cooling device through the human dete ction and temperature control. In experiment,energy reduction is confirmed and the performance of the propos ed system is verified.Key Words : Elevator, Cooling Device, Human Detection, Fuzzy System, Temperature ControlReceived: Feb. 2, 2015Revised : Apr. 6, 2015Accepted: Apr. 7, 2015
