为解决当前隧道瓦斯监控系统存在的不足和实现监控系统“多网合一”、信息化和智能化的迫切需求，建立基于物联网的瓦斯隧道安全监控系统架构，从功能上分为感知层、传输层和应用层3层结构，并就其中涉及到的无线传感器网络、人员定位、无线甲烷监测系统、MIMO无线传输技术、智能视频系统、手机短信报警系统、爆破监控系统等实现瓦斯隧道内环境、人员、设备状态等全面监控所用到的关键技术进行研究，对便携式甲烷检测报警仪和智能瓦斯报警矿灯等新设备在瓦斯隧道中的运用情况进行分析与总结。实现了瓦斯隧道全面感知，传感数据无线传输，瓦斯移动与定点监测，人员精确定位，爆破人、机、环闭锁，远程与多级多员监控，充分实现了施工过程的智能化和信息化，起到了科学有效的监测监控和预警作用，提升了瓦斯隧道施工安全管理水平。

Security Monitoring System for Gas Tunnel Based on Internet of Things

The present gas monitoring system for tunnel has many disadvantages, and it is urgent that multi network integration, informatization and intelligentialization of monitoring system be realized. Hence, the security monitoring system for gas tunnel based on Internet of things is established, which is functionally divided into 3 layers, i.e. perception layer, transport layer and application layer. And then the key technologies, i.e. wireless sensor network, personnel location, wireless methane monitoring system, MIMO wireless transmission technology, intelligent video system, SMS alarm system and blasting monitoring system, that used to realize overall monitoring on status of environment, personnel and equipment are studied. Finally, the applications of new equipments, such as portable methane detection and alarming device and intelligent gas alarm miner's lamp are analyzed and summarized. By adopting the monitoring system mentioned above, the overall perception of gas tunnel, wireless sensor network, mobile and fixed point monitoring of gas, accurate location of personnel, closure of blasting personnel machine ring, and remote and multilevel and multiplayer monitoring have been realized. The informatization and intelligentialization of the tunnel construction, and the scientific and effective monitoring and risk warning have leveled the security monitoring of gas tunnel.
