针对煤矿工人下井后难以了解所处环境安全性的问题,提出了一种基于矿山个人双向信息终端的解决方案。介绍了基于Wi-Fi的矿山个人双向信息传输系统结构与功能,以低功耗GS1011智能芯片为核心,设计并实现智能矿灯嵌入式个人信息终端,分析了双向信息终端的工作原理,设计并实现了智能终端的实时定位算法,利用智能终端技术与三维井巷建模技术构建了煤矿三维虚拟现实系统。系统主要功能为主动感知周围安全环境、与地面及其他矿工信息交流、对矿工进行实时定位跟踪管理。本系统应用于徐州夹河煤矿物联网示范工程,取得良好效果。

A two way information transmission terminal is proposed to solve the problem that underground miner is unable to understand his surrounding environment well. The structure and features of the embedded personal information terminal based on Wi-Fi network technology are given in detail; a low power consumption chip of GS1011 is used as the key chip of smart terminal embedded in a mine-lamp. The main principle of the smart terminal is analyzed and the algorithm of real time location and tracking for the underground miners is designed. Combining with the modeling technique of 3D mine tunnel, a virtual reality displaying system is built. The system is adopted by the internet of things demonstration project in Jiahe Coal Mine, Xuzhou, and obtained a good effect. The main functions of the system include initiative perception of the miner security based on his surrounding environment, the communication with ground and other miners, and real-time location and the tracking management for the miners.
