【摘要】:我國是地質(zhì)災(zāi)害多發(fā)的國家之一,其中西南地區(qū)尤為嚴(yán)重,危巖崩塌、邊坡滑坡等地質(zhì)災(zāi)害頻發(fā),嚴(yán)重影響我國道路建設(shè)的大力發(fā)展和道路交通的安全運(yùn)營。我國公路的大力發(fā)展建設(shè)同時(shí)也使得危巖體崩塌等地質(zhì)災(zāi)害持續(xù)增加,國內(nèi)目前對于公路邊坡危巖體的防治治理措施有很多種,但是各種防治治理措施使用的原理不盡相同,則其特點(diǎn)也有一定得差異。公路危巖監(jiān)控預(yù)警系統(tǒng)作為一種災(zāi)害預(yù)警技術(shù),是對災(zāi)害進(jìn)行實(shí)時(shí)有效監(jiān)控預(yù)警的防治措施,在近些年得到大力的發(fā)展。射頻識別技術(shù)(RFID)作為一種高新技術(shù),已經(jīng)在物流、安保、物品追蹤等方面被廣泛應(yīng)用,本文以射頻識別技術(shù)為基礎(chǔ),構(gòu)建一套新型的公路危巖監(jiān)控預(yù)警系統(tǒng),并以其為重點(diǎn)開展相關(guān)試驗(yàn)研究工作。①論文闡述了公路邊坡危巖體的成災(zāi)機(jī)制、危巖穩(wěn)定性評價(jià)分析和危巖的監(jiān)控預(yù)警技術(shù),研究了危巖崩塌體成災(zāi)的基本原理與各種影響因素,然后對國內(nèi)外現(xiàn)有較為典型的危巖體監(jiān)控預(yù)警方法進(jìn)行研究,從而為基于射頻識別技術(shù)的危巖監(jiān)控預(yù)警系統(tǒng)做技術(shù)支持。②論文對射頻識別技術(shù)的基本原理和標(biāo)準(zhǔn)體系進(jìn)行了論述,包括:射頻識別技術(shù)的基本定義、技術(shù)原理與使用的標(biāo)準(zhǔn)體系,射頻識別技術(shù)的研究現(xiàn)狀、當(dāng)前各產(chǎn)業(yè)應(yīng)用的情況及發(fā)展方向,最后對射頻識別技術(shù)能否應(yīng)用于地質(zhì)災(zāi)害預(yù)警做了論述。③以射頻識別技術(shù)與移動通信技術(shù)為系統(tǒng)重點(diǎn),構(gòu)建以射頻識別技術(shù)為核心的公路危巖體地質(zhì)災(zāi)害監(jiān)控預(yù)報(bào)系統(tǒng)。該系統(tǒng)是由RFID電子標(biāo)簽、閱讀器、后臺軟件系統(tǒng)以及相應(yīng)的管理儲存系統(tǒng)等結(jié)構(gòu)組成。通過野外模擬試驗(yàn)以及對試驗(yàn)結(jié)果的分析和對比,來論證射頻識別技術(shù)在地質(zhì)災(zāi)害監(jiān)控預(yù)警系統(tǒng)的可行性,并得到以下成果:1)該系統(tǒng)的在一般環(huán)境下合理監(jiān)控范圍為30m(與設(shè)備性能有關(guān));2)系統(tǒng)的標(biāo)識設(shè)備(電子標(biāo)簽)需正面朝向信號發(fā)射設(shè)備(閱讀器);3)雨天對系統(tǒng)影響相對較大,當(dāng)雨量較大時(shí),30m監(jiān)控距離丟包率嚴(yán)重;4)系統(tǒng)的穿越障礙能力很差,電子標(biāo)簽和閱讀器需共面運(yùn)行;5)溫度對系統(tǒng)監(jiān)控效率基本沒有影響;6)系統(tǒng)對電子標(biāo)簽丟失和出現(xiàn)的反應(yīng)能力很強(qiáng)。④通過模擬試驗(yàn)的結(jié)論和成果,對該系統(tǒng)提出相應(yīng)的升級改造建議和措施,如加裝雨量計(jì)、采用拉線式天線等,并且對該系統(tǒng)未來發(fā)展進(jìn)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.
