摘要
针对井下现有通信网络存在有线网络易损坏、无线网络通信质量较差等问题,设计了一种井下LED可见光通信系统。该系统利用煤矿井下现有的照明电力线作为传输介质,通过改造LED照明系统,建立可见光通信基站,并配合矿灯移动节点,构成了覆盖巷道和工作面的通信网络,实现了照明和通信双重功能。与井下现有的通信系统相比,该系统无自然光的干扰,且不受电磁波干扰,在安全性、可靠性和稳定性等方面具有明显优势,同时成本相对较低,在井下具有较高的实用价值。
In order to solve problems that wired network is easy to be destroyed and wireless network has bad communication quality existed in current communication network in underground coal mine,a LED visible light communication system was designed.The system uses existing lighting power line as transmission medium,establishes communication network covering roadway and working face through transforming the LED lighting system,and establishing a visible light communication base station,combining with the miner＇s mobile nodes,so as to realize dual functions of illumination and communication.Compared with existing communication system,the visible light communication system has not natural light interference and electromagnetic interference,so it has obvious advantages over security,reliability and stability.Furthermore,for its low cost,the system has high practical value in underground coal mine.
