摘要
针对我国空气污染日益严重的现状以及监测点分布不尽合理、覆盖不全面等特点,重点研究了一种城市空气质量监测系统。考虑到传统供电系统受制于电网位置的缺点,以及提高系统电源稳定性与效率的需要,利用太阳能与风能互补发电,结合最大功率追踪算法(MPPT)进行电源管理,并通过GSM实现与上位机的通信。试验结果表明,系统的能量转换效率保持在70%以上,空气质量监测的结果有较高的准确性。
Aiming at the current situation of air pollution in our country is worsening and the distribution of monitoring points for air quality is not reasonable enough and the coverage is incomprehensive,the urban air quality monitoring system has been researched. Considering the traditional power supply system is subject to the power grid position,and the need of enhancing the stability and efficiency of power supply system,by adopting complementary power generation with the solar energy and wind energy,and combining the maximum power point tracking( MPPT) algorithm for power management,the communication with host computer is implemented via GSM. The experimental results indicate that the energy conversion efficiency of the system maintains above 70%,and the monitoring result of air quality is more accurate.
