摘　　要：监测煤矿井下瓦斯浓度并及时把数据传输到地面,减小爆炸事故发生的可能性,应用Adhoc网络体系结构设计了无线数据采集系统。对系统的下三层进行了设计与实现,物理层应用超低功耗微控制器实现对无线收发模块的工作状态控制;MAC层、网络层分别采用IEEE802.11协议和按需驱动路由协议实现,并对CSMA/CA协议进行了改进。系统经验证运行良好。The coal mine under the ground concentration of gas transmitted up the surface of the earth in time for reason of decreasing probability of exploding accident happens, and designing the wireless data acquisition system by using Ad hoc network architectural structure. The under three layers of the system are designed and implemented. The physical layer of system accomplished by super low energy consumption micro controller unit to control receiving and launch module working state; MAC layer and network layer adopt IEEE802.11 protocol and on-demand routing protocol, and improving up CSMA/CA protocol. System runs well by certification.
