【摘要】：我国是地质灾害多发的国家之一,其中西南地区尤为严重,危岩崩塌、边坡滑坡等地质灾害频发,严重影响我国道路建设的大力发展和道路交通的安全运营。我国公路的大力发展建设同时也使得危岩体崩塌等地质灾害持续增加,国内目前对于公路边坡危岩体的防治治理措施有很多种,但是各种防治治理措施使用的原理不尽相同,则其特点也有一定得差异。公路危岩监控预警系统作为一种灾害预警技术,是对灾害进行实时有效监控预警的防治措施,在近些年得到大力的发展。射频识别技术(RFID)作为一种高新技术,已经在物流、安保、物品追踪等方面被广泛应用,本文以射频识别技术为基础,构建一套新型的公路危岩监控预警系统,并以其为重点开展相关试验研究工作。①论文阐述了公路边坡危岩体的成灾机制、危岩稳定性评价分析和危岩的监控预警技术,研究了危岩崩塌体成灾的基本原理与各种影响因素,然后对国内外现有较为典型的危岩体监控预警方法进行研究,从而为基于射频识别技术的危岩监控预警系统做技术支持。②论文对射频识别技术的基本原理和标准体系进行了论述,包括:射频识别技术的基本定义、技术原理与使用的标准体系,射频识别技术的研究现状、当前各产业应用的情况及发展方向,最后对射频识别技术能否应用于地质灾害预警做了论述。③以射频识别技术与移动通信技术为系统重点,构建以射频识别技术为核心的公路危岩体地质灾害监控预报系统。该系统是由RFID电子标签、阅读器、后台软件系统以及相应的管理储存系统等结构组成。通过野外模拟试验以及对试验结果的分析和对比,来论证射频识别技术在地质灾害监控预警系统的可行性,并得到以下成果:1)该系统的在一般环境下合理监控范围为30m(与设备性能有关);2)系统的标识设备(电子标签)需正面朝向信号发射设备(阅读器);3)雨天对系统影响相对较大,当雨量较大时,30m监控距离丢包率严重;4)系统的穿越障碍能力很差,电子标签和阅读器需共面运行;5)温度对系统监控效率基本没有影响;6)系统对电子标签丢失和出现的反应能力很强。④通过模拟试验的结论和成果,对该系统提出相应的升级改造建议和措施,如加装雨量计、采用拉线式天线等,并且对该系统未来发展进行展望。
[Abstract]:China is one of the countries with frequent geological disasters, especially in southwest China, where dangerous rock collapses, slope landslides and other geological disasters occur frequently. It seriously affects the development of road construction and the safe operation of road traffic in our country. The great development and construction of highways in China also make geological disasters such as collapse of dangerous rock mass continue to increase. At present, there are many kinds of prevention and treatment measures for dangerous rock mass of highway slope in China, but the principles of various prevention and treatment measures are not the same. As a kind of disaster early warning technology, highway dangerous rock monitoring and early warning system is a prevention and control measure for the real time and effective monitoring and early warning of disasters. RFID technology has been widely used in logistics, security and object tracking as a kind of high and new technology in recent years. This paper is based on RFID technology. A set of new highway dangerous rock monitoring and warning system is constructed, and relevant experimental research work is carried out with emphasis on it. 1. The disaster formation mechanism of dangerous rock mass on highway slope, the evaluation and analysis of dangerous rock stability and the monitoring and warning technology of dangerous rock are expounded in this paper. In this paper, the basic principle and various influencing factors of dangerous rock collapse are studied, and then the typical monitoring and warning methods of dangerous rock mass at home and abroad are studied. In this paper, the basic principle and standard system of radio frequency identification technology are discussed, including: the basic definition of radio frequency identification technology, the basic definition of radio frequency identification technology, and the technical support for the monitoring and warning system of dangerous rock based on radio frequency identification technology. The technical principle and the standard system used, the current research status of RFID technology, the current situation and development direction of the application of various industries, Finally, the paper discusses whether radio frequency identification technology can be applied to early warning of geological hazards. 3. The system focuses on radio frequency identification technology and mobile communication technology. A monitoring and forecasting system for geological hazards of dangerous rock mass of highway based on radio frequency identification (RFID) technology is constructed. The system is composed of RFID tag, reader, The background software system and the corresponding management and storage system are composed. Through the field simulation test and the analysis and comparison of the test results, the feasibility of radio frequency identification technology in the geological hazard monitoring and warning system is proved. The following results are obtained: (1) the reasonable monitoring range of the system in general environment is 30m (related to the performance of the equipment) the marking equipment (electronic label) of the system needs to face the signal transmitting equipment (reader 3), which has a relatively large impact on the system on rainy days. When the rainfall is high, the ability of the system to pass through obstacles is very poor when the monitoring distance is 30 m and the rate of packet loss is serious. The temperature of electronic tag and reader running on the same plane has no effect on the monitoring efficiency of the system. (6) the system has strong ability to react to the loss and appearance of electronic tag. 4. The conclusion and results of the simulation test are very strong. Some suggestions and measures for upgrading the system are put forward, such as installing rain gauge, using wire antenna and so on. The future development of the system is also prospected.
