<p>PURPOSE: A flag raising system is provided to simplify the work of flag raising by enabling various kinds of flags to be raised simply and sequentially. CONSTITUTION: A box(16) is installed on the upper part of a lamp post by a bracket. A motor(18) is installed in the box and forward/backward driven depending on the applied direction of a current. A flag pole(20) fixes the upper edge of a flag, and displays the flag in parallel with the ground or raise the flag upwards while performing angular motion in the up/down direction by receiving the driving force of the motor. An illumination sensor(32) is installed on the outside of the box, measures the illumination of a surrounding area and outputs a signal according to the brightness of the surrounding area. A power generation component(34) is installed on the bracket and generates power by converting wind power and solar energy into electrical energy. A remote control device(46) transmits and receives wireless data to control the driving of the motor installed on the lamp post while being connected to an administrator computer.</p> |
