摘要地铁由于其运量大、动力足、无污染等优点，正日益风靡各中大城市，成为政府解决城市交通问题的首选。但铁路隧道作为一类隐蔽的地下设施，结构复杂，通风状态不良，且出入口少，疏散线路长，发生事故后后果严重，会造成惨重的人员伤亡和经济损失，故有效提高隧道环境监测装置的科学性和智能性，是确保隧道施工顺利进行的保障。69188

本文针对当前铁路隧道施工中，面临的环境监测系统中网络布线困难、成本高、实时性差等诸多问题，提出了一种在无线传感器网络基础上的安全监控系统。它通过实时感知、监测和采集网络分布区域内的微观信息，对火灾、突水和有害气体的实时数据进行监控，并在数据超出安全阀值时提供报警，提高了监控系统的自动化程度。

本文设计的基于无线传感网络的隧道环境无线监控系统，具体介绍了有关硬件电路模块组成和软件流程设计过程。其中硬件模块以CC2430芯片为核心，由气体浓度传感器模块、温湿度检测传感器模块、无线传输网络模块、数据处理模块、报警模块和电源模块组成，详细阐述了它们的芯片设计和功能实现。接着，根据系统运作的流程以及需要实现功能的估计分析，设计了每个模块相应的软件流程。其中无线监控系统中的数据采集节点以ZigBee技术完成隧道环境实时信息的采集，无线数据传输网络以GPRS技术完成数据采集节点和路局监控中心的通信。

Design of Railway Tunnel Environment Monitoring System based on Wireless Senior Network

Abstract

Metro is increasingly popular in major cities, as its large capacity, enough power, pollution, and the government has made it as the first choice to solve urban traffic problems. But railway tunnel is complex, poorly ventilated premise, and fewer entrances , evacuation routes ,can cause heavy casualties, so the advanced monitoring equipment is the guarantee for tunnel construction successfully carried out.

Aiming railway tunnel operators monitor facing the current environmental monitoring network wiring difficulties, high costs, and poor real-time problems, proposed a wireless sensor networks based on the safety monitoring system.It does this by sensing real-time, all kinds of microscopic tunnel monitoring and gathering information distribution network in the region.

  Based on the design of this essay tunnel environment monitoring system wireless wireless sensor networks, specifically introduced the related hardware and software flow circuit module design process. The hardware module consists of various sensor modules, wireless network transmission module, data processing module, alarm module and power module, and elaborated on their chip design and function realization process.Next, the process operation of the system and the need to realize the function of the estimated analysis, design the corresponding software processes. In this paper, a wireless monitoring system data acquisition nodes ZigBee technology to complete real-time information collected tunnel environment, wireless data transmission network with GPRS communication technology to complete data collection node and the railway bureau monitoring center.
