The Research Of Perilous Rock Monitoring Method Based On RFID

With the rapid development of the national highway traffic construction, building scale in southwest mountain road is also growing rapidly, along with a variety of geological disasters are increasing road construction, especially roads dangerous rock mass destruction will collapse and highway operations management safe use caused great impact. Highway road accidents each year due to dangerous rock mass collapse caused uncommon, so the current control measures for the prevention and treatment of highway slope there are many dangerous rock mass. Due to the principle of prevention and treatment of various control measures used vary, it also has some characteristics have differences. Crag road use as a monitoring and early warning systems disaster warning technology, disaster prevention measures to effectively monitor real-time warning, the strong growth in recent years. Radio Frequency Identification(RFID) as a high-tech, and is widely used in logistics, security, asset tracking and other aspects, this paper based on radio frequency identification technology, build a new highway crag monitoring and early warning systems, and its for focus on relevant experimental research.â‘ The paper describes the mechanism of highway slope disaster dangerous rock body, dangerous rock stability analysis and evaluation of monitoring and early warning of dangerous rock technology, mechanisms and conditions inside and outside influence, introduces more typical of existing domestic and international crises by studying unstable rock formation rock monitoring and early warning method for monitoring and early warning of dangerous rock radio frequency identification technology to make technical comparison.â‘¡Dissertation on the basic theory and key technologies of radio frequency identification technology is analyzed, including: basic concepts of RFID technology, key technology, radio frequency identification technology research status, trends and possibilities apply to monitoring and early warning of dangerous rock.â‘¢With RFID technology and GPRS technology as the core, based on the establishment of a road slope of things dangerous rock mass monitoring and early warning systems. The system is composed of RFID tags, readers, software systems, and back-end storage systems and other appropriate management structures.Based on field tests and simulation analysis and comparison of the test results to demonstrate the feasibility of RFID technology in geological disaster monitoring and early warning systems, and has been following results:1) The system in general environmental monitoring in the range of reasonable 30m(and device performance related);2) Identification device(RFID) systems need obverse signal transmitting apparatus;3) Rain relatively large impact on the system, when rainfall is large, 30 m from the packet loss rate monitor serious;4)Crossing barrier system is poor, electronic tags and readers need coplanar run;5) Temperature had no effect on the system monitoring efficiency;6) System for electronic label is missing and that the responses are strong.â‘£Through simulation experiments, to verify the radio frequency identification technology in the field of monitoring and early warning systems crag road is feasible to provide effective support for the improvement of the experimental data to upgrade the system and put into use.
