基于RFID的公路危岩智能安全监测与现场报警系统

Intelligent Safety Monitoring and Hazard Warning System of Highway Dangerous Rock based on RFID

山区公路边坡危岩体崩塌、落石灾害频发,对公路交通的安全运营具有重大影响。危岩崩塌具有多发性、突发性、强破坏等特点,且危岩分布点多、线长、面广,在有限的公路养护费用下投入大量的人力、财力、物力对公路危岩进行监测是十分困难的。文中基于无线射频识别技术(RFID)提出了一种新的危岩监测预警方法,提出了工作原理与流程,构建了监测、预警系统的基本架构,研发了声、光报警装置及时将崩塌灾害信息告知来往车辆,避免二次事故发生。该监测方法成本低,易于安装布设,可丰富危岩监测方法,为危岩监测预警和治理决策提供技术支持。

Rock collapse disasters in mountainous highway have tremendous impact on traffic safety. The rock collapse frequently and suddenly occurs with strong damage, and dangerous rocks have many distribution points on long lines and wide range. It is difficult to input many manpower, material resource and funds to monitor the dangerous rocks under the current limited road maintenance cost. In this paper based on radio frequency identification technology （RFID）, a new method of dangerous rocks monitoring and warning is proposed, and working principle and procedures are put forward, the basic structure for monitoring and early warning system is constructed, sound and light alarm devices can ＂inform collapse information to vehicles timely so as to avoid the occurrence of the secondary accidents. The monitoring method has many characteristics such as lower cost, easy installation and can provide technical support for dangerous rock monitoring, hazard warning and management decision.
