实现道路科学照明、绿色照明的关键问题是能够测量和控制到每一盏路灯,无线传感网络是解决这一问题最好的技术之一。选择Freescale公司MC13213芯片,设计了一种嵌入式无线通信模块,使整条道路的每一盏路灯自主联网,接受控制中心的指令,反馈路灯的各种状态,根据环境光强度和时段自动调节照明亮度,在保证道路照明质量和视觉舒适的情况下,节约电能20%~30%。
The ability to measure and control each street-lamp is the key issue to realize road scientific lighting and green lighting. Wireless sensor network is one of the best technologies to solve this problem. MC13213 chip is used to design an embedded wireless communication module in this paper. Each street lamp on the whole road could independent network, receive instruction from control center, send various states feedback of street lamps, and automatically adjust lighting levels according to the ambient light intensity. This technology could ensure the quality of road lighting, visual comfort and save energy 20% -30%.
