Hinkley Point C的坡度移动监控
案例分析
Author:史蒂夫·瑟古德（Steve Thurgood）
新的Hinkley Point C（HPC）核电站在英格兰萨默塞特郡的建设中将生产3.2 GWE可靠的低碳电力 - 足以为600万英国的房屋供电。该项目超出了大约7％的英国需求的低碳电力供应。它将为该地区带来社会经济利益，从增加当地就业机会到建立可持续的区域供应链，并提高新的培训设施和资格。
HPC的坡度监控程序与Kier BAM合资企业启用作品一起开始，并构成了自动化总站（ATS）系统，倾斜计，延伸计，应变计和压力计的混合物。监视程序共同监视针对特定设计参数的垂直斜率移动。Kier Bam Anafing工程和构造的斜坡为核电站和工作区域创造了基础，以跟随承包商。设置应用的监视解决方案以记录施工和操作阶段的任何斜率运动。
Handling a large-scale project
HPC项目范围意味着任何安装的ATS系统都必须具有集成的光学和GNSS调查控制网络，以将固定的控制从稳定的位置转移到预期看到地面运动的区域内的共同控制棱镜。结合Leica Geosystemsmonitoring solution和its distribution partnerSCCSwas chosen to deliver the ATS system through considered investigations. The solution comprised ofLeica Nova TM50监视总站亚博5分钟快三driven byLeica GeoMoS并支持微泡沫星*净调整工具。该系统每两个小时运行一次，测量斜率监视棱镜的规格±1mm。报告的监测结果报告针对建筑和操作设计触发器 - 超越预期设计的地面运动将实现其他结构地面控制措施。
监视计划和ATS系统的目标是确保针对设计的斜率移动性能，最终确保健康和安全。

Selecting the right equipment
决定硬件和软件提供商都是关于合作伙伴关系的。对于HPC项目，这是一个关键因素。只有一家公司，无所不包的协作才能满足性能，耐用性和可靠性方面的预期监视需求。
“Hinkley Point C is located adjacent to the Severn Estuary and is exposed to the Atlantic’s prevailing winds. I needed a product that could withstand these conditions, and I believed Leica as a respected and established brand was a safe selection to meet the project requirements,” said Ben Crossland, Senior Monitoring Surveyor at HPC.
在比较了市场上可用的各种解决方案之后，HPC促进了Leica Geosystems及其分销商SCC的集体力量。该决定背后的推理是多层的 - 设备必须承受现场的条件；这些仪器必须完美地执行并使测量师控制网络集成。HPC需要一个“全包”软件包，包括软件，硬件，service and specialist support to meet HPC’s automated total station systems’ needs.

解决方案
Leica Nova TM50监视总站亚博5分钟快三provided durable and precise instruments with the Leica GeoMoS monitoring software. Survey control measurements were processed by SCCS’s bespoke automatic adjustment script, which uses MicroSurvey Star*Net to adjust the ATS control network before every scheduled array slope monitoring measurement cycle. This system provided a fully integrated network, which would help remove the risk of false movement caused by survey control movement. The applied solution consists of the following components:
Software:
- 3xLeica GeoMoSMonitor software
- 1xLeica GNSS蜘蛛Software
- 1xLeica Infinity调查软件
- 1x微观级星*网络adjustment software
- 1x SCCS SNASI bespoke automation scripting
硬件：
- 40 xLeica Nova TM50监视总站亚博5分钟快三
- 6 xLeica GMX910GNSS smart antenna
- 25 xLeica GRZ122 prisms
- 2000 GMP104 and other monitoring prisms
- 2 xLeica Nova MS60多阶段
- 1 xLeica LS15数字级别
- 1 xLeica Nova TS60总站
- 3 x PC具有独立功率和备份存储
- 46 X带GSM/WLAN收音机和太阳能电池板的通信和功率外壳
- 60 x TPS/GNSS/PRISM安装柱（高1.2〜1.8m）和TPS的保护外壳
Leica LS15数字级别和Leica Nova TS60机器人总站are used manually for survey control and manual monitoring verification checks to validate the ATS network was operating correctly. Together with these checks, HPC had sixLeica GMX910智能天线通过Leica GNSS蜘蛛软件进行控制。一个天线坐在一个永久的基站上；其他人在工作区域内分布。天线的位置与Leica GRZ122 prisms允许ATS网络使用位置作为固定控制。调查方法的集成允许实时位置检查以确保相对稳定的位置不会受到施工的影响。In areas where prisms were obstructed, aLeica Nova MS60多阶段was used to scan the relevant zones. The data was then imported to Leica Infinity for cloud comparison. The MS60’s scanning ability was also used within GeoMoS when automated scanning was a preferred option due to impracticality of installing and maintaining prisms in dangerous areas.”
“We placed our GNSS systems differentially – one in a stable position (and fixed), the others in relatively stable positions, that are also considered pseudo-fixed. The potential for the positions to move was the reason for including GNSS as part of the solution. In this way, we could ensure unforeseen movement of fixed control positions that we deemed stable, was captured and addressed,” informed Crossland about the technical challenge. “We started with just prisms then realised our reference frame was flexing,因此，我们询问了供应商的建议，后者通过集成GNSS来帮助解决我们遇到的网络稳定问题。”
We needed to trust the equipment and the expert suppliers
“The main benefit of engaging in a supply partnership with Leica Geosystems and SCCS are the instruments themselves. This is where we trust the brand. Plus, it comes with great support,” Crossland summarised their experience. “You know what you paid for – the high quality is worth the investment. We are satisfied with how it works and are always eagerly expecting new advancements.”
另一个决定性的因素是所有事物无缝合作的方面。互操作性对于设置复杂的系统作为HPC监视至关重要。因此，Geomos平台将这些多个数据源组合到均匀的监视系统中。由于项目的动态性质，ATS系统布局每周都会改变。该公司始终努力优化该操作，因为新的工作区域开放/关闭并改善了监视过程，以确保劳动力的安全。
自定义解决方案
Complex projects require the equipment/software provider to understand the customer’s needs thoroughly and always offer suggestions leading towards the optimal solution. The partnership went beyond the mere software/hardware support – with cooperation in operation plan optimisation, and custom builds related to the communication network (e.g., WLAN spanning the entire project).

都是关于数据的
每两个小时，一年中的每一天，Geomos都会完全自动完成计划的任务，以指示ATS系统收集一系列测量，以计算和更新ATS位置。一旦更新，他们就测量了斜率监视棱镜并计算出任何变形。在Geomos中报道了Prism反对基线的运动，并自动发送给客户的观看门户Missionos。Maxwell GeoSystems Mission OS组合了所有HPC监视数据，调查棱镜数据，倾斜度，应变计，压力计计和延伸仪。所有监视数据均通过每日部分审查小组进行审查，其中评估了针对建筑和操作触发器的运动。GMX910数据以每小时为平均每24小时以每小时为平均，以增强GNSS的数据稳定性，可靠性和准确性。GMX910处理的平均结果用于与ATS网络测量集成的Star*NET中，以实现所有系统的验证。
建议
Once the slope monitoring project is completed, the stock instruments are assigned to other areas, especially those facing and combating line-of-sight issues, generally caused by construction programmes.
“我可以很容易地建议徕卡呈规则的产品。亚搏彩票手机版下载They are very transparent – I like to look into the GeoMoS system data, understand how the system operates, integrating the fine detail of observation and computation. The open access to raw data and log files was especially useful for a surveyor, so I understood how and why my system operated. I’ve used other products in the past which were supplied by 3rdparties and missed that same transparency where you could drill down into specifics of measurement and the data behind it,” Crossland concludes.
