METHOD FOR REDUCING ROADLAMP POWER-CONSUMPTION BY USING MOBILE COMMUNICATION BASE STATION IN RELATION WITH VEHICLE MOVEMENTS

摘要

PURPOSE: A streetlight power saving method according to a vehicle operation which uses a mobile communication base station is provided to turn on a streetlight group which a vehicle passes through and a streetlight group thereafter and turn off a corresponding streetlight group if the vehicle passes through the corresponding streetlight group. CONSTITUTION: A vehicle information receiving unit (120) receives vehicle information which includes vehicle speed information and expected drive path information. A storage unit (110) stores streetlight information. A calculation unit (130) calculates a location of a vehicle which drives through the corresponding expected drive path within a base station coverage with reference to the streetlight information. The calculation unit determines one or more streetlight groups to be turned on among streetlight groups within the coverage. A first transmission unit (140) transmits the unique number of the streetlight group to be turned on.
