Project FAIRCOP - Feasibility of Converging Beam LIDAR for Improving Crane Operational Productivity

“有人建议，根据为起重机设计的新型激光风力激光雷达设备的精确风力测量，起重机作业可以计划停止和启动，这可能会使建筑行业更有效率，也更安全。风激光雷达是一种远程风廓形技术，通过测量空气中粒子的激光后向散射来获得视线风速。相交光束激光雷达使用三个激光训练在一个点上，并获得真正的三维风矢量。时间就是金钱。然而，起重机依赖于基本的风速表，这些风速表没有提前预警，也没有指示大型起重机结构上风场的变化。同时，采用粗风预报实现了提前日、提前小时调度，但该预报存在风速估计不确定性。通过为建筑行业设计新的激光雷达系统，可以克服这些困难。该项目将确认将会聚光束激光雷达应用于建筑行业，特别是起重机应用的技术和经济可行性。项目合作伙伴已经在为风能行业规划和运营（但不包括风电场建设）的会聚束激光雷达产品和工艺商业化而合作，预计所获得的知识可以以新的方式重新应用于建筑行业的其他商业应用。该团队已经为风能行业设计、制造和测试了光束导向激光雷达。他们之前也参与过风能行业。这为参与建筑行业和设计用于建筑行业的激光雷达产品提供了相关的技能和经验。可行性研究将包括详细评估各种建筑子行业的市场规模，如海上风电场建设、陆上风电场建设、摩天大楼建设、桥梁建设和其他子行业。进入市场的途径可以是直接的高价值制造，也可以是技术许可。除了改进起重机操作和有效定义操作天气窗口外，还可以显著提高工人和公众的安全。高达四分之一的起重机事故可以直接归因于极端的风，而非风故障引起的问题往往会因风而加剧。主要的问题是预报和现有的设备不能准确地警告极端的阵风或突然的变化。会聚束激光雷达可以做得更好。”

"It is proposed that the construction industry may be made more efficient and also more safe when crane operations are scheduled to stop and start according to accurate wind measurements from new laser based wind LIDAR devices designed for cranes. Wind LIDAR is a remote wind profiling technique that measures the laser backscatter from airborne particles to obtain line of sight wind speed. Intersecting beam LIDAR uses three lasers trained onto one point and obtains the true 3D wind vector.Time is money. However, cranes are depending on rudimentary anemometers which give no look ahead advance warning and they also give no indication of the variation of the wind field across large crane structures. Meanwhile coarse wind conditions forecasting is employed to enable scheduling on a day-ahead and hours ahead basis but this forecasting is subject to wind speed estimation uncertainty. By designing new LIDAR systems for the construction industry these difficulties can be overcome.The project will confirm the technical and economic feasibility of applying converging beam LIDAR to the construction industry and crane applications in particular. The project partners are already working together for commercialising converging beam LIDAR products and processes for the wind industry planning and operation (but not including wind farm construction) and it is envisaged that the knowledge gained can be re-applied in new ways for other commercial applications for the construction industry.The team have designed, built and tested beam steering LIDARs for the wind industry. They have also engaged with the wind industry previously. This provides relevant skills and experience for engaging with the construction industry and designing LIDAR products for use in the construction industry.The feasibility study will include detailed assessment of the market sizes of various construction sub-sectors such as offshore wind farm construction, onshore wind farm construction, skyscraper construction, bridge construction and other sub-sectors.The route to market can be through direct high value manufacturing, or through technology licensing.In addition to the improvement in crane operations and efficient definition of operational weather windows there are significant benefits to improve safety for workers and the public. Up to around a quarter of crane accidents can be directly attributed to extreme wind whilst problems due to non-wind faults are often exacerbated by the wind. The main problem is that forecasts and existing devices do not accurately warn of extreme gusts or sudden changes. Converging beam LIDAR can do much better."
