重型建筑中的活动监控：KäppeliDigital Ag
KäppeliDigital Ag是一家成长中的，以未来为导向的公司，位于瑞士萨尔凡斯（Sargans），不断寻找解决方案，以改善他们为客户提供的服务和支持。根据这种理念，该公司决定提供自动化和竞选监控。由于项目的快速执行需要增强对工人安全和结构健康的重点，因此监测的重要性正在增长。
The related case study, “Monitoring and the Future of Construction，”describes an automated monitoring project Käppeli Digital carried out during a sewage treatment plant renovation to ensure the safety of a nearby railway line. This article focuses on the context, tools and methods of campaign monitoring and presents a variety of interesting campaign monitoring projects Käppeli Digital has completed for a wide range of customers.
What is campaign monitoring?
In campaign monitoring, a surveyor in the field completes manual measurements at defined intervals. For example, a surveyor initially measures points for the current epoch with a total station and then transmits the data to the office for analysis. The surveyor then repeats that same measurement weekly, monthly or over another determined period to calculate site movements with respect to the null epoch, or the initial results. In automated monitoring, on the other hand, an instrument is set up, configured to take measurements at defined, often frequent intervals and left in the field for an extended time.
在自动和广告系列监控之间做出决定
自动化监控和竞选监控之间的决定降低了两个因素 - 测量间隔和预期成本。该决定在于客户，并取决于何时实施自动监视的主要问题。如果需要每天的测量，则每天将测量师送到站点进行测量，从成本或时间的角度来看可能没有意义。
“We take a very analytical approach to tenders – we always keep the client's interests in mind. As project descriptions are often general, we provide a precise projection,” explains Käppeli Digital’s Managing Director, Pascal Bonderer.
“我们查看整个项目持续时间，并提出最佳解决方案。对我们来说，最好的解决方案比我们的员工仅使用可靠的工具和软件，还包括实施方法，即自动化或广告系列监控。”博德勒说，总结了他们的方法。“客户的最终决定是由总成本和安全要求驱动的。”
The experts at Käppeli Digital suggest appropriate measurement intervals that will provide data accuracy and eliminate any outliers caused by changing environmental conditions, like rain, snowfall or fog. Normally, a test phase is carried out before the start of a monitoring project to check all the project’s conditions and circumstances. Well-planned monitoring can also eliminate accountability and safety issues.
Moving from manual to automated monitoring
每个测量师在职业生涯中都遇到了监视，甚至在不知不觉中。一旦对象进行了多次测量并随后分析了数据，就可以处理一个初始的手动监视项目。
In phase two of manual or campaign monitoring, manual measurements become semi-automated. When a totally automated installation is not required but completely manual measurement and analysis methods have become inefficient, some automation of the monitoring process enhances campaign monitoring solutions. For example, with the TPS monitoring application, the surveyor "teaches" the total station how to carry out the survey and which points to measure. The application then automatically measures the points with the simple push of a button and performs quality control at the same time. Although surveyors are still on site conducting the survey, the features of Leica Geosystems’ automated total stations make getting started with campaign monitoring simple and efficient.
KäppeliDigital的广告系列监控工具箱
尽管KäppeliDigital定期安装和运行自动监视解决方案，但其大多数监视项目包括广告系列监视。对于监视任务期间的单人测量，KäppeliDigital AG使用以下Leica GeoSystems设备：
- Leica TS16total station (and the previous model, the Leica TS15)
- Leica RTC3603D激光扫描仪
- Leica LS15digital level
- Leica CS20field controller
This equipment makes up the ideal monitoring solution when combined with the following software:
- 现在，Leica Geomos！监视服务
- Leica Captivate3 d事业中d software
- Leica Cyclone 3DRpoint cloud management and analysis software
Interesting projects for a wide range of customers
铁路监控：
- 自2017年以来的长期监控: This project involves a rail track area survey of approximately 1.3 kilometres, including the displacement of the mast pointsusing aLeica Nova MS50 MultiStation.Surveyorsconduct settlement measurements of the mast points using a Leica LS15 digital level, measure the change in inclination with a high-precision inclinometer and evaluate the data using Leica GeoMoS Now!
- 跟踪调查（定居点测量）：该项目通过在铁轨卧铺和链纳支架上永久安装的棱镜进行了测量位置变化，随后分析了Leica Geomos中的测量结果！
监视地下矿井中的支柱：
The pillars in an underground mine were scanned with a Leica RTC360 3D-laser scanner. Then a point cloud was meshed and compared to current scans using Leica Cyclone 3DR for point cloud management and analysis.
Settlement checks:
- New build：该项目检查了最近建造的建筑物，以使用Leica LS15数字级别进行定居，并且现在在Leica Geomos中分析了数据！
- Extending a silo plant: A total station was used with fixed prisms to measure the settlement of the existing tower. The data was imported into Leica GeoMoS Now! for analysis.
- 监视发掘工作：The total station, measuring prisms and GeoMoS Now! combination described above was used to monitor ground anchors.
- Settlement monitoring of adjacent structures:Construction projects can impact adjacent buildings. To ensure safety, measurements are carried out with Total Stations on measuring prisms and analysed in monitoring software.
- Track underpinning:当在铁路轨道下构建管道时，定居测量对于继续工作至关重要。为此，KäppeliDigital使用Leica LS15数字级别，并分析Leica Geomos中的数据！
Excavation monitoring:
An excavation pit, which was open for 6 months, had a depth of up to 12 metres. The soldier pile wall, which prevented soil from sliding into the excavation pit, consisted of shoring systems with retaining and sheet-pile walls. Käppeli Digital’s surveyors monitored the bracing of the retaining wall using MultiStation measurements of fixed prisms and analysed the data with Leica GeoMoS Now!
Käppeli数字：建筑行业的数字未来
In campaign and automated monitoring, digitalisation plays a key role in the solutionsKäppeli数字offers to clients in the construction industry. From automated total stations enabling repeated and consistent measurements, to sophisticated monitoring software that enables robust analysis,informative reports and timely alerts, digitalisation in monitoring is key to Käppeli Digital’s strategy now and as they grow their business into the future.
