摘　　要：为了解决瓦斯监测节点部署制约开采进度和传统瓦斯传感器调校周期短的问题,采用JENIC5139模块架构了无线瓦斯传感器监控系统,该系统由红外瓦斯传感器节点、井下中心站和井上瓦斯监控计算机组成,通过红外瓦斯传感器实现瓦斯浓度的检测,基于无线传感网络的井下中间站实现检测数据的及时发送、瓦斯传感器的在线调校和参数动态设定,通过上位机不但可以随时了解瓦斯传感器的工作状态,还可以实现瓦斯传感器的动态调零、非线性动态修正。In the use of traditional gas detectors,the disposition of gas detecting nodes restricts the mining process and the period of gas sensors calibration is short.To solve such problems,a new wireless sensor gas monitoring system based on JENIC5139 modules is designed.This system is composed of infrared gas sensor nodes,underground center and gas monitoring computer on the surface.Infrared gas sensors are used to detect the density of gas and wireless sensor network（WSN） is used to send the data in time,calibrate gas sensors on line,and set parameters dynamically in the wireless sensor network based underground intermediate center.Additionally by using the supervisor computer,the operating state of gas sensors can be acquired whenever necessary and the dynamic zero modulation and nonlinear dynamic adjustment can be realized.
