主要城市建设网站的数字监控

数字监控

Karlsruhe每年有30万居民,城市主要地区有16万辆汽车和1.9亿辆乘客,在德国西南部的运输规划中起着决定性的作用。A5高速公路不仅会影响大卡尔斯鲁厄地区的规划场景,还影响了州街B10的城市内使用。这是该地区最重要的市中心东西方连接。卡尔斯鲁厄市以及联邦政府巴登·伍滕伯格(Baden-Wuerttembg)州通过启动两个非凡的隧道项目来对交通和整个地区的发展做出反应,以通过“合并解决方案”来缓解地面交通。

“联合解决方案”等项目没有supporters only. Construction noise, disruption of daily life, costs, pollution and environmental restrictions are only a part of the potential issues that must be taken into account when working on this kind of large-scale urban projects. The City of Karlsruhe and the Karlsruhe Rail Infrastructure Society (KASIG) as builders have set up a long-term and very early information campaign for this purpose. This takes place in the form of a project website, but also through public events and an information centre. The aim of the builders as well as of the participating construction companies and consortia was also to make the best use of the possibilities of digital solutions for construction site documentation. Leica Geosystems' solutions for surveying used by Karlsruhe Ingenieurbüro GEO GmbH are the decisive factors in this digital documentation.

第一天的最高精度

建筑公司埃德。Zublin Schleithare responsible for the construction of the Kriegsstrassentunnel next to the Ettlinger Tor. Combined with the second tunnel in Kaiserstrasse, both construction projects are "The Combined Solution" for the City of Karlsruhe, which will help to significantly alter the traffic situation in the inner city from 2020 and 2021 respectively. In the Kriegsstrasse, this means that the vehicles are brought under the earth, while trams, pedestrians and all bicycles move above ground. On a path of 1,600 meters, the road tunnel dramatically changes the cityscape - as well as during the construction work. The construction planning and subsequent construction supervision is also given special importance for this reason. The objective of the construction supervision cooperation, consisting of DB Engineering & Consulting, Emch+Berger and BUNG, is to get the highest accuracy in surveying, preservation of evidence and monitoring. Before working on new construction sections, the task was the initial surveying of the construction area as well as an area of 50 meters in all side streets. The expected accuracy of the data was 2 cm. This task was taken over by the team of IngenieurTeam GEO, using the Leica Geosystems Unmanned Aerial Vehicle (UAV). Equipped with the RTK and GNSS module, this technology allows airborne data to be collected parallel to the on-site operation, delivering highly accurate data by combining the UAV and the Sony Alpha 6000 with a 20mm lens.

在市中心飞行时的特殊挑战

Around the project, the Federal Court of Justice and the Karlsruhe State Theater are critical buildings. As is customary in the case of tunneling construction site, it must be ensured that the construction does not lead to unplanned changes in the environment. Any reductions or unwanted volume changes must be excluded. This exclusion has to be documented and monitored. Conventional methods can only be used to a limited extent in parallel to construction measures for security and time reasons. The use of an UAV was then recognised as an optimal solution for data capturing in the sense of an efficiency-oriented project process. The advantages of the 3D measurement and the monitoring compared to a purely point-based data acquisition using terrestrial methods lie in particular in the various usage scenarios of the generated data. They can not only answer questions from a surveying engineer's point of view, they can also be used as a basis for the planning of the traffic routes during construction work. They can be used in pro- and retrospective construction planning and are a decisive factor in volume calculation almost in real time.

使用无人机的优点一方面是在市中心飞行的挑战。因此,必须在自动化飞行计划中考虑到城市的狭窄,因此必须专门定义飞行路线和高度规划。由于现有的基础设施和开发而导致的起重机,植被和可能的磁场干扰对飞行的潜在干扰起作用。因此,本杰明·布斯(Benjamin Busse)是在Ingenieurteam Geo使用测量无人机领域的经验丰富的专家,因此在计划阶段特别强调了所有利益相关者的参与。

布斯说:“德国的新无人机法规不允许在联邦街道上航班。”“由于与所有利益相关者之间的良好关系,我们获得了B10上城市内航班的特殊许可,并通过交通,行人和电车。”

The advantages of using UAVs are on the one hand side, the challenges of flying in the city centre are on the other hand side. Thus the narrowness of the city has to be taken into account already in the planning of the automated flight, and, therefore, the flight route and altitude planning has to be defined specifically. Potential disturbances of the flight by cranes, vegetation and possible magnetic field disturbances due to the existing infrastructure and development play a role. Benjamin Busse, an experienced expert in the field of the use of surveying drones at IngenieurTeam GEO, has therefore placed special emphasis on the involvement of all stakeholders during the planning phase.

Digital results and economic benefits

除了经典的矫形器外,客户还期望具有文档,数字高程模型和点云的高分辨率单图像。同时,要求对交通路线计划进行检查。这是根据现有计划与原始计划相结合的。由于航班的非常好的数据和高信息质量,现在计划进行季度监视,关键的数量计算以及通过鸟类的视频和照片的补充,并从鸟类的角度使用视频和照片无人机解决方案的帮助。

该决定的原因很快总结了:使用常规的测量和测量方法,不仅可以收集数据明显减少数据,而且由五人组成的团队需要六周才能提供所需的结果。两个人组成的无人机工作流程团队只需要7天。通常,将使用Leica Geosystems总站。亚博5分钟快三使用常规方法的客户的成本比使用UAV解决方案要高出180%。从无人机运营商的角度来看,货币的观点更具吸引力:使用无人机解决方案的Ingenieurteam Geo的成本仅占传统方法成本的五分之一。

“我们将无人机技术视为工具箱的一部分,” Ingenieurteam Geo的联合创始人兼董事总经理Martin Schwall补充说。“从客户的角度来看,无人机允许快速和数字业绩具有许多优势,以获取更多信息。”

数字工作流提供了许多优势

Leica GeoSystems的无人机解决方案的使用提供了许多优势。与建筑项目相关的过程的数字化始终取决于高数据质量和密度。例如,UAV航班中的信息不仅可以用于计划和监视,还可以用于机器控制和项目通信任务。在进一步的开发步骤中,无人机的数据也将无缝集成到莉卡地理系统的软件解决方案中。结果不仅更快,而且可以量身定制以满足个人要求。尽管常规方法生成选择性数据,但它们不会捕获图像数据,因此不允许数字可视化。使用基于无人机,相应的传感器技术(此处高分辨率RGB摄像机)和用于后处理和数据处理的合适软件的数字端到端解决方案提供了真正的好处。除图像外,这主要是3D测量信息,基于图像数据的并行检查的选项,与日常业务平行捕获的数据以及对本地工作的测量工程师和无人机的更高安全性操作员。生成的数据是回答现有问题和将来的问题的基础,并将有助于存档从第一天开始所有施工的进展。

Leica Geosystems无人机无人机产品经理Valentin Fuchs表示:“作为下一步,Leica Geosystems将将无人机解决方案完全集成到用于构建,监视和测量的软件解决方案中。”“帮助我们的客户可视化信息,并使用所收集的无人机数据自动化和加速流程是未来发展的更广阔情况的一部分。”
