基于物联网技术的矿山井筒安全监测系统设计

摘要

An intelligent safety monitoring system of mineshaft based on internet of things is designed and developed to improve the transmission rate of HD videos and realize the video data sharing. Based on the three-layer architecture model,the functions and interconnection schemes of the four sub modules which are front-end video capture device,mineshaft control de-vice,mineshaft video data (MVD) server and management software are introduced. The system adopting H. 264 compression codec algorithm to compress the video data improves the efficiency of video transmission. The MVD server is used to share vid-eo data,and multiple threads are used to deal with video data transmission among multiple mineshafts simultaneously. The sys-tem adopts the internet of things technology integrating the video capture,storage and analysis together,which can simplify the operation and improve the transmission rate of HD video data. It can also share the video data between different mines.%为解决矿山井筒安全监测系统中高清视频数据传输效率低及数据不能共享问题，设计了一个基于物联网技术的矿山井筒安全监测系统。系统基于物联网的3层架构，由前端视频采集装置、井上控制装置、视频数据服务器和后台管理软件4个模块组成，介绍了各个模块的功能及其互联方案。系统采用H．264编码协议对高清监控视频进行编码压缩提高传输效率，利用视频数据服务器实现数据共享，并使用多线程并发数据传输方案解决同时接收多个矿井的视频数据传输问题。该系统将视频采集、存储和分析部分通过物联网技术有机结合在一起，有效简化了系统的操作，提高了高清视频数据的传输速率，实现了不同矿井间视频数据的共享。
