New Technology of Grid Line Selection: Three - dimensional Airborne Lidar Mapping System
"Note that the path ahead, ready to take off!" Recently, Chongqing Shuangqiao Economic and Technological Development Zone, Chengdu passenger dedicated railway for external electrical survey route selection process the scene, one loaded with dynamic three-dimensional laser radar mapping system delta smooth take-off, Chongqing Surveyors at the Power Design Institute took two hours to collect the data for the project by selecting the best grid path. Airborne Lidar 3D Surveying and Mapping System is currently an advanced geodetic technology and a new technology put into operation in the field of electric power construction and surveying in 2013. It is put into operation for the first time in the line selection of the power grid of Chongqing Power Grid Corporation. In all stages of the project, laser radar three-dimensional mapping system plays a different role. In bidding and tendering phase, bidding and tendering for design and construction can make full use of the data and information obtained by this technology to realize the reproduction of the actual project environment, improve the optimization of project proposals, accurately measure the project volume and reasonably determine the design and construction costs. During the construction phase, staff can build on the data collected by this technology and the specific needs of the project to build a three-dimensional visual digital sand table and an electronic database to enhance the informatization level of construction management. In the completion phase, the project can be based on the system to establish digital archives of all stages, improve the scientific management level. At the same time, the system data retention time is long, late planning or inspection line management can call the data at any time. After the project is put into operation, the supervisory unit can also realize the visual management of stay-at-home and understand the situation of line corridor in real time. This not only can effectively reduce the workload and difficulty of line inspection but also can grasp the health level of power grid equipment in time and improve the power grid Safe and stable operation of the reliability. The application of three-dimensional airborne Lidar mapping system will move the transmission line to the computer as a whole to realize the optimization of "indoor bird's eye view" so as to enable the survey design to be on the scene and effectively protect the environment and improve work efficiency. It is reported that the next stage, Chongqing Electric Power Design Institute will be in the 500-kilovolt power plant expansion projects sent to use this technology. What is airborne lidar three-dimensional mapping system? Airborne lidar three-dimensional mapping system is a collection of laser scanner, GPS and inertial navigation systems and high-resolution digital cameras and other technologies in an integrated optical and electrical integration system, through the active survey of direct measurement Ground accurate and clear three-dimensional coordinates. The technology is not affected by the weather and the sun's elevation angle. It can conduct surveying around the clock and has strong vegetation penetration. The laser penetrates the vegetation to obtain real ground information, greatly reducing the work of field survey and improving work efficiency. After the data are collected, the designer can combine the result data to optimize and plan the planning and design of the measurement area, which can effectively reduce the amount of vegetation and reduce the house demolition, which has good economic and social benefits. Compared with the traditional manual measurement, the system overcomes the shortcoming of traditional measurement period long, complex terrain personnel is difficult to enter, inconvenient to consider the line as a whole, and improve the planning and design efficiency. Moreover, the data processing system obtains higher degree of automation and accuracy, data collection does not require a dedicated data workstation and stereoscopic 3D glasses, the naked eye can be viewed directly, reducing the cost of the post.
