Master electronics apparatus, electronic apparatus and controlling method thereof

Abstract

A master electronic apparatus, an electronic apparatus, and a controlling method thereof where the master electronic apparatus includes a communication interface and a processor. The processor receives first data and second data regarding predicted power consumption amounts corresponding to respective tasks of a first electronic apparatus and a second electronic apparatus, calculates summed-up values of the predicted power consumption amounts for respective times, and compares the summed-up values with instantaneous power amount limits for the respective times. The processor, based on the summed-up values being smaller than the instantaneous power amount limits, transmits a task approval signal to the second electronic apparatus, and based on identifying a time a summed-up value is greater than or equal to the instantaneous power amount limit, transmits a control signal controlling an operation in the identified time to at least one of the first electronic apparatus and the second electronic apparatus based on priorities.
