线在哪里？AR和GNSS对公用事业的增强感知

作者：Renata BarradasGutiérrez

通过10,794.6公里的高架线和地下电缆以及超过2,000公里的天然气管道系统的网络有效地分发电力和天然气是一项巨大的努力。Vorarlberger Energienetze GmbH（Vorarlberg Netz）是电力和天然气网格电网操作员，该网络在奥地利最西端的州Vorarlberg维持该网络的供应可靠性高和优异的服务质量。

除了网络的扩展外，公司面临的一些挑战是地形，三分之二的土地区域位于山区，无法可视化线路，因为94％的电缆在地下。

“知道这些线路的位置在确保不间断的供应方面起着重要作用。理论上听起来很简单的内容通常会导致实践中的挑战。完成施工后，表面上不可见电源电缆和管道。一段时间后，即使是最有经验的员工也无法再回答“线路在哪里？”的问题。Vorarlberg Netz的GIS管理员兼开发人员Sebastian Drexel解释说。“This is one of the main reasons why each line is surveyed and centrally saved within the company’s GI-system. So far, restoring lines in nature has been a time-consuming task performed by specially-trained staff.”

在3D中以调查级准确性可视化实用程序

To make the task of restoring lines easier, vorarlberg netz is using state-of-the-art Augmented Reality (AR) and GNSS. AR technology superimposes digital information on an environment providing actionable information to solve problems or a specific task. Combined with GNSS, users can visualise and position utilities with survey-grade accuracy.

数字化可视化3D中的地理参考实用程序使Vorarlberg Netz现场工作人员可以直观地实时体验地下供应基础架构，并通过智能设备增强自然环境。“欧r service technicians are enthusiastic about the simple and intuitive visualisation that is possible through Augmented Reality,Drexel说。

Vorarlberg Netz使用了Leica GG04加上智能天线结合VGIS公用事业, a utility-grade AR system for ESRI ArcGIS designed for municipalities and public utility companies. The GG04 plus smart antenna collects high-accuracy geospatial data in real time, even in the most demanding locations without the need for a mobile data connection. The antenna also pairs with all existingLeica Zenohandhelds and a wide range of Android, iOS or Windows® smart devices.

To precisely position utilities, the team uses the GG04 plus withHXGN SmartNet，世界上最大的参考网络，用于开放标准校正服务。VGIS和GG04加上智能天线之间的集成使NMEA元数据和调查级访问，几厘米定位。Vorarlberg Netz团队快速，轻松地配置了GG04 Plus GNSS智能天线，可在智能手机，平板电脑或Microsoft Hololens上与VGI一起使用。

“We opted for the Leica GG04 plus antenna, as it is relatively low-priced, small, handy and can be coupled with mobile devices. The last of these points is crucial since the AR software runs on an Android or iOS tablet or smartphone,”解释Drexel。“由于简单的设置，与移动设备的连接，可靠性和产品的高精度相比，建议使用VGIS和GG04 Plus的组合。”bob综合app下载

AR和Georected实用程序的应用和利益

VGIS, paired up with GNSS, allows users to ‘see’ GIS utilities in real time through the ground. This improves situational awareness, helps to locate utilities faster, with fewer errors, and in a safe manner. vorarlberg netz is currently using AR at a pilot stage to develop the know-how, search, validate, and introduce practical applications. Currently, the company is benefiting most from four different applications:

1. 检查建筑物或工厂覆盖物的供应路线以及沿线断层的位置。
2. 在施工活动之前，自然界的线条恢复。
3. Location of resources that are not easily visible, e.g. shut-off devices covered by gravel or snow.
4. 对外部公司的协调和澄清。

vorarlberg netz is also looking to integrate the visualisation of georeferenced utilities in combination with 3D models. The electricity and natural gas network grid operator uses a terrestrial laser scanning unit from Leica Geosystems to capture point cloud data of existing infrastructure which can further be converted to BIM models. This information is going to be the basis for the facility management, responsible for the maintenance of e.g. buildings or transformer stations.

“除了计划新对象外，还需要使用激光扫描仪收集库存数据，在我们公司中使用现代BIM技术。结合3D GIS数据，这为设施管理领域开辟了新的可能性，并以增强现实的可视化数字双胞胎的可视化。”Vorarlberg Netz的地球形式负责人AndreasMätzler说。

使用GNSS对公用事业的AR的好处包括：

• 可视化3D中的GIS数据，以定位并找到地下公用事业。
• Spot faster and fix on the ground GIS data location issues, reducing collection costs.
• Improve route control for overcrowding, fouling and location of faults along cable routes.
• 简化测量师对电缆的利益。
• 搜索和找到不容易看到的资源和地下基础设施，例如覆盖的碎石或雪。
• 改善现场协调和澄清严重工作。

提供多种服务来运输能源和天然气

尽管母公司Vorarlberg Netz从传输网络的进料点运输了电能和天然气Illwerke VKW AGalso performs general technical surveys, seabed surveys and engineering geodesy for tunnel advancing. For these endeavours, the company also uses Leica Geosystems solutions, including:

• 速符
• GNSS receivers
• Levelling instruments
• 激光scanners

“我们使用Leica Geosystems产品来测bob综合app下载量电气和气体线以及为外部客户提供GIS服务的一部分，”Vorarlberg Netz的网格和地理信息负责人Marco Ess解释说。
