The combination of surveying and machine control technology helps Ängö Entreprenad to be on time, on specs and on budget

作者：Per Norell

Ängö Entreprenad AB is a Swedish company specialized in earthworks for housing development, plumbing and drainage for residential areas. The company was founded back in the 1980’s by Dan Johansson. Today, the company employs approximately 25 people and a handful of independent contractors.

We meet the crew on a sunny Wednesday in September on a job site close to Gothenburg, Sweden. Five people work here full time on preparing the construction of four semi-detached houses. The project was started in the spring of 2020 and must be finished by autumn 2021.

“这在多种方面都充满挑战”。explains Mikael Persson who works as surveyor on the project.

地形是山区的，狭窄，位于现有住宅区的中间，但直到现在，一切都按照计划进行。我们有好人，我们的机器配备了最新的机器控制技术，Leica MCP80控制面板和MC1软件。我们还拥有Leica GeoSystems的POL，ICG70 T GNSS Rovers和CC80平板电脑，使我们能够连续进行销售，以便我们的挖掘机操作员一直都知道该怎么做，这要归功于机器控制上的实时可用信息控制板。

更快，更安全地静止不动

Ängö Entreprenad started with measuring and stake-out in 2009, but it was not before 2014 when the company truly understood and experienced all of the benefits of digitalisation. Today, they have six of their excavators equipped with machine control solutions from Leica Geosystems and two surveying poles with iCG70 T GNSS rovers and iCON CC80 field tablets. This allows the company to perform measurements themselves in addition to the surveying services they currently outsource.

“We purchased the new iCG70 T rover and CC80 field tablet in 2009. Before that, we used the GS14 GNSS smart antenna and CS35 tablet controller from Leica Geosystems",explains Persson.“对我来说，新的Model ICG70 T，具有倾斜补偿是我的一个重大改进，他只能进行测量。我得到了一个非常精确的测量，甚至不必保持杆子。这个GNSS漫游者解决方案非常易于使用，当我不必在确切点握住杆子时，我可以更快，更安全。足以使两米长的碳杆的尖端放在测量点上，从而为我们节省了很多攀登。”

Sharing real-time data with the entire team

Persson用其设备测量的所有数据通过基于云的协作平台Leica Conx以及与其他GNSS Rover合作的同事直接与机器运营商共享。

This gives a very good overview and transparency of the construction site and what needs to be done and where, as Persson and his colleague supplement each other depending on who is closest to the actual location.

“我实际上不是数据专家，但是Leica Geosystems的解决方案是如此准确，合乎逻辑和用户友好，以至于我很容易学习如何使用它们。”珀森说。“Our surveying equipment communicates directly with the machine control solutions through ConX, as well as, we, who are responsible for the measurement can also communicate with each other through the cloud-based services. In addition, Leica Geosystems offers a platform called ‘myWorld’ that gives a really good overview of all the products that we have, when they need service and the subscriptions that are available. It sounds more complicated that it is,”assures Persson. “If there any questions, Leica Geosystems offers excellent support.”

通过机器控制独立工作，更有效

One of the excavators on site is a Volvo ECR235EL equipped with the latest technology from Leica Geosystems. The control panel mounted on the excavator is the MCP80 where the one-for-all MC1 software is running. Henrik Wirkstrøm is in charge of the excavators, and he has worked for Ängö Entreprenad for five years.

“I have been driving excavators for approximately 15 years, but I only came into contact with machine control five years ago, when I started here,”says Wirkstrøm.“通常，机器控制使我能够更加独立地工作，从而使我更加高效。我可以在网站上四处走动而无需等待利益，导致停机时间很少。我真的很喜欢旧的挖掘机系统，但是新的解决方案更有效。”

Wirkstrøm还将继续与倾斜旋转器传感器的直接通信以及面板的用户界面的设计。

“最大的区别是MC1现在与倾斜旋转器传感器通信，这是一个很大的优势，因为我99％的时间使用倾斜旋转器。面板更大也很高兴。更容易看到并按下右键。对我而言，最重要的是，Leica Geosystems的远程支持效果很好，如果我们遇到任何问题，它们总是在那里，”结论Wirkstrøm。
