In this paper, we study the wind and solar hybrid lamps testing system which is based on wireless communication design. The collected data will be calculated. The paper analyses six typical points to research the solar energy, wind energy to the battery energy conversion. Moreover, the paper also analyses the scenery energy and fan speed data for four seasons, providing scientific basis for eco-city management analysis of local natural resources utilization.
