摘要:
结合信息网络技术发展的趋势,从提倡绿色阅读、节约能源的角度,分析了将可见光通信技术应用于图书馆信息网络建设的可行性;并结合实际条件对采用可见光通信网络接入技术所带来的节能效果进行评估。结果表明,与无线局域网相比,采用可见光通信网络接入技术可获得约4%的总体节能效果。

Abstract: A new trend in the area of information network technology appears. Aiming at providing green reading for readers and decreasing energy consumption, the feasibility of applying visible light communication to accessing the information networks in libraries is analyzed. Also, the effects of energy conservation of applying VLC to library network are evaluated. Numerical examples show that in comparison with present wireless local network, the visible light communication access network can save 4% energy consumption on the whole.
