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

“有人建议，当起重机作业计划根据为起重机设计的新的基于激光的风力激光雷达设备的精确风力测量值停止和开始时，建筑业可能会变得更有效率，也更安全。风激光雷达是一种远程风廓线测量技术，它测量来自空气中颗粒的激光后向散射，以获得视线风速。交叉光束激光雷达使用三个激光器对准一个点，获得真实的3D风矢量。时间就是金钱。然而，起重机依赖于基本的风速计，这些风速计不能提供前瞻性的预先警告，也不能提供大型起重机结构上风场变化的指示。同时，采用粗略的风况预测，以实现提前一天和提前几小时的调度，但这种预测受到风速估计不确定性的影响。通过为建筑行业设计新的LIDAR系统，这些困难可以克服。该项目将确认将会聚光束LIDAR应用于建筑行业，特别是起重机应用的技术和经济可行性。该项目的合作伙伴已经在共同努力，将用于风能行业规划和运营（但不包括风电场建设）的会聚光束激光雷达产品和流程商业化，并设想将所获得的知识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、建造和测试了光束转向激光雷达。他们以前也参与过风能行业。这为从事建筑行业和设计用于建筑行业的LIDAR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个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。进入市场的路线可以通过直接的高价值制造，除了起重机操作的改进和操作天气窗口的有效定义之外，还存在改进工人和公众的安全的显著益处。高达约四分之一的起重机事故可直接归因于极端风力，而非风力故障引起的问题往往会因风力而加剧。主要的问题是，预报和现有的设备不能准确地警告极端阵风或突然变化。会聚光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."
