我国煤矿事故频出，严重影响了正常的生产工作和井下人员的生命安全，因此更加显示出井下安全信息系统对于煤矿安全生产的重要性。 现今的井下安全信息系统都是以工业总线为基础，构成有线的通信传输网络。但是伴随煤矿开采速度的加快，有线网络存在覆盖率，扩展性，灵活性方面的不足，为了更好的解决这个问题，引入无线个人区域网络(wireless personal area network，简称WPAN)，为近距离范围内的设备建立无线连接，把几米范围之内的多个设备通过无线方式连接在一起，使它们可以相互通信甚至通过网关设备接入局域网或者互连网。 ZigBee技术作为一个新近出现的WAPN通信技术，以其协议简单、功耗低、组网容易等特点，在家庭自动化、智能建筑、工业监控领域具有广阔的市场空间。 论文首先全面分析研究ZigBee协议架构、网络拓扑以及组网技术，认识ZigBee的技术优势和应用，针对井下环境的需要，设计以ZigBee技术为基础，适用于煤矿井下巷道局部区域的无线网络模型。 本文重点研究Ad hoc网络两种典型路由协议的路由建立方式:AODV(Ad Hoc on-demand Distance Vector Routing，Ad Hoc按需距离向量协议)、DSR(Dynamic Source Routing Protocol，动态源路由协议)。针对不同的网络容量（移动节点密度）对两种路由协议进行了模拟，选取数据分组投递率、端到端的平均延时、平均跳数、路由开销作为参数，在网络仿真平台NS2上进行仿真，对仿真结果进行详细的分析，分析移动节点密度对网络性能的影响，其结果对于工程应用，无线网络的部署有现实的指导意义。

The colliery accident occur frequently in our country,which affects the normal work and shows the importance of colliery security information system. Nowdays,colliery security information system is based on industry bus,and Composed of communication network. With the development of colliery exploitation, wired networks exist the lack of covering,expansibility,agility. Therefore,using the wireless network in the system becomes more important .The concept of Wireless Personal Area Networks (WAPN) has been brought. ZigBee technology is an up-to-date communication technology,with the characteristics of simple Protocol,less power and so on. It illustrates a good broad space in the field that automation system for home, intelligence for building and monitoring system. The ZigBee protocol construction, network topology and network technology were analyzed comprehensively.Besides,the ZigBee technical superiority and application were knew. The wireless network model of partial region that is suitable in the shaft tunnel were desighed base on the ZigBee technology, in accordance with requirements of security environment in the mine. The way of routing build about two typical routing protocols that AODV and DSR were mainly researched in Ad Hoc networks. Basing on the different capacity network (mobile node density), the packet delivery ratio, average delay,mean hop and route load were selected as the parameter on NS. The simulate results of protocols mentioned above were provided and analyzed,which has much practical guidance to the application of engineering and deploying of wireless network.
