Monitoring Melbourne’s railways

City infrastructures are not built overnight. In between planning, design and construction, there are other crucial activities – just like monitoring happening at the same time.

澳大利亚墨尔本的火车网络正在进行重大改造，并正在进行一些项目以帮助解决拥堵。为了改善墨尔本周围的旅行，维多利亚州政府正在消除危险且拥挤的铁路交叉路口，这将为驾驶员和行人提供重大安全改善。这个主要项目将为每天前往城市的成千上万的通勤者提供更多的频繁服务。

此外，地铁隧道项目将为大都市网络增加新的地下车站和下一代高容量的火车 - 释放了墨尔本铁路网络上更多的火车。这也意味着将安装下一代，高容量的信号传导，从而使火车可以安全地靠近，更频繁地将火车运行。

为了准备繁忙的墨尔本铁路基础设施，客户转向Heading and Associates,a professional surveying and project management firm specialising in survey, construction supervision, property and environmental survey, and design applications, to perform railway track monitoring.

Real-time monitoring with safety in mind

As part of the Level Crossings Removal Project, the team at Heading and Associates was tasked to monitor more than 300 meters of rail across two sites. To deliver this, the team installed an automated monitoring system to monitor rail movement 24/7, including aLeica Nova MS60andLeica Nova TS60total station and deployed 178 Leica Geosystems monitoring prisms mounted to the rail to monitor at 30-minute frequency day and night.

在某些情况下，应用传统手动监控可能不是一种实用方法，例如标题和员工团队正在解决的项目。该项目需要在白天进行许多观察，并且实施自动监控系统是有意义的，因为它对客户更具成本效益。

这Leica GeoMoS监视解决方案用于监视24/7的移动，提供分析铁路轨道并量化几何变化并接收实时警报所需的数据。

“自动监视也意味着与白天和黑夜进行监控相比，这是一个更安全的解决方案 - 这意味着人员不必进入铁路走廊”Michael Payne表示,领导和同事oring and laser scanning specialist. For our client, this makes it a more cost-effective solution over the length of the project as there are no applications for safety permits or additional resources required such as Track Force Protection Coordinators.

选择仪器时，即使仪器依靠仪器读取数百个棱镜，使用MS60和Thets60的关键因素是仪器的准确性，稳健性和长期服务间隔。这使得MS60和TS60成为标题和员工团队的首选总站。bob apple

Power and communication were some of the factors considered when planning for the project. More specifically, the team needed to install solar systems to run the instruments as there was no 240V power supply on the project site. If the team needed any technical support, they knew they could rely on Leica Geosystems Australian distribution partner C.R. Kennedy.

C.R. Kennedy’s experience with solar and data transfer solutions specific to monitoring application was vital. Utilising the 4G network via the Leica ComGate10 simplified an otherwise complicated communications process.

自动数据传递

为了向客户提供准确，及时的数据，团队使用了Geomos Monitor和GeoMoS Now! Using GeoMoS Monitor, the team set thresholds for three limit levels, and in case any of these were exceeded, the team and nominated recipients were able to receive an SMS and e-mail in real time immediately after breaches. GeoMoS Now! was used to analyse and visualise the data with the help of graphs, showing limit levels as a background colour.

即使涉及以图形格式表示数据，标题和协会团队也接受了自动化。现在使用Geomos！该团队创建了一个报告模板，并计划通过每日电子邮件生成和发送。

“我们真正喜欢的解决方案是我们可以自动化报告创建。视觉和图形表示使我们的最终用户可以简单地在图表上解释和查看每个单个点与警报级别所在的移动 - 包括每天早晨自动发光的报告以及每周的数据报告透明佩恩说。

I have worked with automated monitoring across various projects since 2012, and it has come a long way. All the reporting is shared with the clients – it’s our main deliverable. Leica GeoMoS is easy to use; it is user friendly and we can easily input all the parameters we need. The integration from GeoMoS Monitor to GeoMoS Now! makes it easier to gather and present information concisely to our clients,”佩恩添加了。

至理名言

我们问迈克尔·佩恩（Michael Payne）是否有任何实用建议可以与考虑自动监控的行业专业人士分享。

Payne shared his top two:

1. Always consider the placement of instruments.监控点之间的角度可以瞧t of difference to how effective the system is, in this case, being the prism placement. For this project, the team ensured that the instrument was placed above and far from the target site.

2. Good baselines of data are important. The team suggest having two to three weeks of data prior to their commencement of to assess any trends so that they can be eliminated from being considered as movement. A lot what they do with data is trend analysis and having access to baseline data is always helpful if the project constraints allows it.
