【摘要】 针对矿井瓦斯事故频发、现有矿井瓦斯监测有线通信系统急需向无线通信系统改进的实际情况,文章提出了将分布于井下的所有瓦斯传感器节点纳入一个智能化、结构灵活的无线网络系统,组成以传感器节点为依托的层次化且具有本安特性的瓦斯传感器网络系统。该系统在主井中以光纤为传输通道,在巷道中以无线电为传输通道,可随时根据井巷结构变化改变节点位置或者增加和减少节点数量。更多还原

【Abstract】 Aiming at the practical situations of frequent accidents on mine gas and existing mine gas wire communication system needs to be improved towards wireless communication system,the paper put forward all nodes of gas sensor distributed in underground were brought into an intelligent and flexible wireless network system, so as to form a gas sensor networks system with layering and characteristic of (intrinsical) safety which relayed on the sensor’s node.The system had transmission channels of fiber-optic in main shaft and wireless in road,and could change the location of node or increase or decrease the number of node at any moment according to the structure change of mine.更多还原
