【摘要】：煤田火灾分布很广，中国、印度、美国、俄罗斯、中亚等国家和地区都普遍存在。中国由于特殊的地理位置和气候条件，成为世界上煤田自燃灾害最为严重的国家。据初步估算，，我国煤田火灾每年至少造成200亿元的经济损失。现有的煤田火灾温度监测主要是人工测温法，测温法由于是点接触，预测预报范围小，安装、维护工作量大、不能提供实时监测和预警，特别是探头、引线极易破坏，在实际应用中受到技术和经济的限制，不宜大面积探火采用，不能很好的满足煤矿安全生产的要求。由于煤田发火区域有隐蔽性、着火点分散、被测点多、距离远等特点，使得对煤田火灾的预防、监控和治理非常困难。无线感知网络技术与温度传感器相结合的监测方法，是近几年来一个新的发展趋势，改变了传统温度传感器系统拓扑结构，适应更多温度测量的应用场合。大峰矿开采的太西煤是我国为数不多，具有“三低六高”特点的优质无烟煤，长期以来大峰矿区由于煤层自然发火的原因，火区面积达上万平方米，国家资源遭到重大损失。同时，火区形成的高温给煤炭开采和安全生产带来严重影响。为了抢采高温区的煤炭资源，大峰矿与西安科技大学合作，提出了大峰矿火区无线温度监测预警系统的研究，在现场应用取得了较好的效果。本文根据大峰矿火区温度监测的实际需求，设计了集ZigBee技术、嵌入式计算机控制技术、传感器技术、数据采集技术、数据库技术于一体的大峰矿火区无线监测预警系统。本文给出了系统的整体组成框架，对系统的功能和性能需求、工作原理和工作方式进行了分析，设计了无线温度监测节点、主控节点的硬件和软件，以及上位机监控软件，描述了监控系统的应用环境，给出了现场布置方法，论述了系统的无线感知网络的监控机制，分析了工业性试验和现场应用效果。
[Abstract]:Coal fires are widely distributed in China, India, the United States, Russia, Central Asia, and other countries and regions. China, due to its special geographical location and climatic conditions, The coal field spontaneous combustion disaster is the most serious in the world. According to the preliminary estimate, the coal field fire in our country causes at least 20 billion yuan of economic loss every year. The existing coal field fire temperature monitoring is mainly manual temperature measurement method, and the temperature measurement method is point contact. The prediction and forecast range is small, the installation and maintenance work is heavy, the real-time monitoring and early warning can not be provided, especially the probe, the lead wire is easy to destroy, and it is restricted by technology and economy in the practical application, so it is not suitable for large area fire detection to be used. It can not meet the requirements of coal mine safety production well. Because of the characteristics of coal field fire area with concealment, scattered ignition point, many measured points and long distance, the prevention of coal field fire is made. Monitoring and management is very difficult. The monitoring method which combines wireless sensing network technology with temperature sensor is a new development trend in recent years, which has changed the topology of traditional temperature sensor system. Suitable for more applications of temperature measurement. Taixi coal mined in Dafeng Mine is a few high-quality anthracite coal with the characteristics of "three low and six high" in our country. For a long time, due to the natural combustion of coal seam, the area of fire area in Dafeng mining area amounts to ten thousand square meters. At the same time, the high temperature formed in the fire area has seriously affected coal mining and safety production. In order to seize the coal resources in the high-temperature areas, Dafeng Mine cooperated with the Xi'an University of Science and Technology. The research of wireless temperature monitoring and warning system in Dafeng mine fire area is put forward, and good results are obtained in the field application. According to the actual demand of temperature monitoring in Dafeng mine fire area, this paper designs ZigBee technology, embedded computer control technology, sensor technology, data acquisition technology. The wireless monitoring and warning system of Dafeng mine fire area is integrated with database technology. This paper presents the overall framework of the system, analyzes the function and performance requirement, working principle and working mode of the system, and designs the wireless temperature monitoring node. The hardware and software of the main control node and the monitoring software of the host computer are described, the application environment of the monitoring system is described, the method of field arrangement is given, and the monitoring mechanism of the wireless perceptual network of the system is discussed. The industrial test and field application effect are analyzed.
