Case Study

结合技术的好处；雷达的检测速度和通过总站的测量来解释运动的可靠性。亚博5分钟快三
On 6 February 2020 at a landfill in Zaldibar, northern Spain, thousands of cubic metres of waste collapsed. Tragically, the collapse killed two employees of the refuse company responsible for the site. The landslide spread beyond the landfill and onto a highway, the busy AP-8 which runs from east to west across Basque Country. Interbiak, the public company in charge of managing the highway, immediately instructed engineering partner信息to set up a system to monitor the collapsed material. InfoTOP installed a Leica Geosystems automated monitoring system configured to alert the engineers – and via them, the rescue team and emergency services – of any further movement or instability.
增加稳定滑坡的人的安全性
滑坡从垃圾填埋场中拖动了数千立方米的材料（一些有毒和易燃），垃圾填埋场占据了宽30米，高约四米。为了开始救援行动，需要快速控制斜坡的稳定性所需的紧急服务。在不稳定且不稳定的情况下，他们需要一个警报系统来警告他们，如果废物再次移动。
这是一个具有挑战性的装置。由于该站点的危害，Infotop的监视系统需要完全遥远，而无需任何手动测量。它只能在滑坡的400 - 800米内安装，更重要的是，它必须在没有任何操作员的情况下24/7运行。在速度方面，系统收集的数据需要自动处理，并将报告生成并发送到Infotop的地质合作伙伴Ingekfor interpretation. For coordination with the distributed team, data had to be accessible from anywhere. Finally, the monitoring system needed to be configured to send alerts to the technicians in real-time by SMS and email.
两个监控系统用于完整图片
面对这些条件，Infotop设置了将总站与雷达结合的自动监测解决方案。亚博5分钟快三他们安装了两个Leica Nova TS60total stations with mobile communications provided by aLeica Comgate10router with 4G technology via a virtual private network (VPN). The total stations performed measurements using a series of more than 100 prisms installed in the area. Installed on concrete pillars, one total station was positioned next to the radar and the second one in an area near the landfill – to measure the prisms that were not visible from the first station. Measurements were then managed byLeica GeoMoSsoftware installed on a virtual cloud infrastructure.
In addition, anIDS HYDRA-G- 基于雷达技术的遥感监测系统安装了，以进行连续的测量扫描。水平覆盖率为120度，垂直覆盖30度，除了植被隐藏的区域外，这覆盖了大部分危险区域。Hydra-G设计用于预警和实时测量，用于剪裁中的亚毫米位移，Hydra-G提供了动作的实时数据，并传输到IDS Guardian为解释和报警管理软件。
Why were both systems combined? Speed, reliability and depth of data
The radar system allowed movements to be identified across hectares in seconds by comparing consecutive measurements through interferometry (the interference of waves) over a large distance range, detecting movements of ±0.1mm at up to 800m. While highly sensitive, it can only monitor within its line of sight. Not all areas of the landslide allowed radar measurement due to its inclination and parts being hidden by vegetation. Therefore, multiple total stations covered any blind spots and measured prisms in both the radar coverage and shadowed areas. The prism data helped the engineers and geologists understand each area's true movement, building an exact picture of the 3D movements taking place. These highly complementary technologies provided a combination of speed from radar detection with reliable spatial information on the movements via total station measurements. Leica Geosystems and IDS GeoRadar technology and software form Hexagon Geosystems’ monitoring solution.
Connectivity and instant alerts
The Leica GeoMoS and IDS Guardian data processing software allowed InfoTOP to automate the system so that the data could be instantly and remotely shared with specialists at Ingek for interpretation.现在的怪异！是一个易于使用的Web界面，使地质学家可以从任何位置分析情况，即24/7。该系统还配置了一系列实时警报，如果超过配置的阈值，该警告立即发出警告。
Safety in the immediate aftermath and throughout the phased disaster recovery process
Talking about the monitoring system, Oskar Moral from InfoTOP said, "It allows us to have an early warning if any movement happens, to ensure the safety of the staff as well as to have control of the stability. A great advantage is that everything is automated without the need for operator intervention to control the equipment day-to-day; this has allowed us to obtain immediate results without further processing. We have not found another solution that matches the advantages offered by the Hexagon Geosystems’ monitoring system."
"Furthermore, it is a scalable system that allows us to manage the sensors as this difficult project evolves continually."
