基于电力线载波技术的白鹤梁水下照明控制系统

Application of underwater lighting control system based on power line carrier in in-situ protection works for White Crane Ridge Inscription

长江三峡库区白鹤梁水下照明工程是国内唯一投入使用的深水照明工程。在阐述电力线载波通讯最新技术成果的基础上,结合水下题刻文物保护工程的特点,提出了采用电力线载波通讯技术实施水下照明工程升级改造的方案,并验证了方案的可行性。详细介绍了控制系统组成、电力线载波芯片和应用模块的原理、电力线载波通讯的组网结构特点、LED灯具等关键技术设备。可为今后水下照明工程设计提供参考。

The underwater lighting project of White Crane Ridge Inscription in Three Gorges Reservoir Area is the only deepwater lighting project that has been put into use in China. On the basis of presenting the newest power-line carrier communication technology and in combination with the characteristics of protection project of White Crane Ridge Inscription, we put forward the solutions using power line carrier for underwater lighting engineering upgrading and reconstruction, and the feasibility of the scheme is verified by series of experiments. The composition of control system and principle of chips and module of the power-line carrier, and the network characteristics of the power-line carrier, LED lamps and lanterns are introduced in detail, which could provide significant reference for other underwater lightening system.
