<p>To improve the efficiency and accuracy of temperature control by controlling the internal temperature of a greenhouse by corresponding to the external environment of the greenhouse, provided is a method of controlling a multiplex environment control system. It includes a first step which controls the opening width of the ventilation window of the greenhouse according to an opening/closing level which corresponds to a predetermined proportional control table, when a first deviation temperature calculated by a difference between the internal temperature of the greenhouse and a predetermined setting temperature according to the growth environmental data of crops, excesses a predetermined reference deviation temperature; a second step which calculates a second deviation temperature with a difference between the setting temperature and a re-measured internal temperature, when a waiting time calculated by corresponding to the setting temperature and the internal temperature of the greenhouse passes; and a third step which controls the opening width of the ventilation window of the greenhouse according to the opening/closing level induced by the proportional integration control, when the second deviation temperature excesses the first deviation temperature.</p> |
