Solar Powered Automatic Controlled Advertising Light Box System
This paper introduces a solar powered automatic controlled advertising light box system functioning box rotation and poster cycling displaying of each panel, which overcomes the disadvantages .of ordinary advertising light boxes of humdrum displaying and high energy consumption. The system includes three parts which are box rotation system, poster scrolling system and single-axis sun tracking system which can improve the solar energy efficiency and reduce energy consumption. Sun tracking system which effectively combined the sun angle tracking and photoelectric tracking method can automatically switch between the work mode and hibernate mode according to time and weather condition so as to maximize energy efficiency. A hierarchical control strategy which contained main control system and sun tracking system is adopted to control light box rotation, panel displaying and sun tracking at the same time. The solar advertising light box system was verified by tests that with the hierarchical control strategy the power generated by solar panel increased 38.2％ than fixed panel. Experiment results show that the light box works stably and has potential to apply under the situations where cable laying is not convenient.
