摘要
为了对瓦斯浓度进行全方位、无人值守的实时监测,降低煤矿生产安全隐患,将无线传感器网络与现代VOIP网络相结合,设计出了一种适合瓦斯监测和语音通信的综合业务数字网;通过对瓦斯涌出的动态变化特性、实际环境特征的分析,提出了一种用于煤矿瓦斯监测系统,研究了一种切实可行的瓦斯传感器网络的体系结构,包括物理通信模型、MAC协议、路由协议,并提出了瓦斯传感器网络的感知节点和监控中心的结构和功能.
To monitor the gas strength with whole orientation, real time and unmanned, and reduce the hidden safe trouble, a gas monitor and voice communication Integrated Services Digital Network （ISDN） was designed by using wireless sensor network and wireless communication and voice on IP technology. By analyzing the gas pulling up dynamic characters and the surroundings in coal mine, a gas monitor system was presented. The structure of the gas monitor network was studied include the physical layer, MAC protocol, routing protocol etc. The structures and functions of node controller and monitor center were designed.
