MDR-3715 智能落石防护网监测报警系统

        在自然环境复杂多变的山区、边坡地带，落石滑坡灾害是威胁交通安全与人民生命财产安全的一大隐患。为了有效预防和减轻此类自然灾害带来的影响，现代科技手段——智能落石防护网监测报警系统应运而生，成为保障道路安全、提升防灾减灾能力的重要工具。该系统通过在易发落石区域安装高科技防护网，并配备先进的倾斜碰撞监测终端，实现了对潜在灾害的实时监测与报警，极大地提高了应对自然灾害的效率与准确性。
        In the mountainous and slope areas with complex and changeable natural environment, rockfall landslide disaster is a hidden danger threatening traffic safety and people's life and property safety. In order to effectively prevent and mitigate the impact of such natural disasters, modern scientific and technological means - rockfall landslide monitoring system came into being, and has become an important tool to ensure road safety and improve disaster prevention and reduction ability. The system can realize real-time monitoring and early warning of potential disasters by installing high-tech protective nets in areas prone to falling rocks and equipped with advanced tilt collision monitoring terminals, which greatly improves the efficiency and accuracy of dealing with natural disasters.
       系统能够实时监测易落石区域防护网护栏的状态，自动识别护栏是否发生倾斜、损坏，并第一时间通知相关部门进行处理。如此一来，不仅可以显著提升道路交通安全管理水平，减少因落石而引发的各类事故，还有助于降低边坡、隧道沿线的道路交通运维成本，营造更为安全和谐的道路交通环境。
        The system can monitor the status of the protective fence in the rockfall area in real time, automatically identify whether the fence is tilted and damaged, and notify the relevant departments for processing at the first time. In this way, not only can significantly improve the level of road traffic safety management, reduce all kinds of accidents caused by falling rocks, but also help to reduce the cost of road traffic operation and maintenance along the slope and tunnel, and create a more safe and harmonious road traffic environment.

        （一）总体设计/Overall design

        基于“窄带物联网”技术，我司专门研发了集北斗/GPS定位、姿态检测（三轴加速度计或三轴陀螺仪）、振动检测、电量提醒于一体的“智能护栏碰撞监测终端”（简称“终端 ”），并将其安装在易落石区域所需的主被动防护网上；当所安装的主/被动防护网被落石撞击或损毁时，由于相应主/被动防护网发生了姿态变化、产生振动或发生位移、角度等变化时，则“终端”通过NB-IoT信号发出报警信息到“系统”平台；管理人员通过平台或手机APP或微信公众号可对相关设施进行监控，一旦平台收到“终端”发出的警示信息后，立即自动转发到用户手机产生报警，使用户第一时间知晓落石塌方路段，可以尽快采取措施，恢复路面清洁和保证道路畅通。
        Based on "narrowband Internet of Things" technology, our company specially developed the "intelligent guardrail collision monitoring terminal" (referred to as "terminal"), which integrates Beidou /GPS positioning, attitude detection (three-axis accelerometer or three-axis gyroscope), vibration detection and power reminder, and installed it in the active and passive protection network required by the rockfall area; When the installed main/passive protection network is hit or damaged by falling rocks, the corresponding main/passive protection network has a change in attitude, vibration or displacement, Angle, etc., then the "terminal" sends an alarm message to the "system" platform through NB-IoT signal; The management personnel can monitor the relevant facilities through the platform or mobile APP or wechat public number. Once the platform receives the warning information issued by the "terminal", it will automatically forward it to the user's mobile phone to generate an alarm, so that the user will know the rockfall section at the first time, and can take measures as soon as possible to restore the road clean and ensure that the road is smooth.
