摘　　要：在燃煤电厂,如何及时盘存煤场各煤种存煤量,以便优化燃煤库存、完善配煤作业,进而科学合理地进行经济生产调度,一直是重要的课题。传统的人工盘煤方式误差大、成本高且资源浪费严重,超声波测量技术受时间差及粉尘的影响大,基于计算机视觉的测量技术需要插值拟合修正模型,因此,都存在较大误差,已被市场淘汰。重点介绍了目前研究和应用较多的激光盘煤技术和无人机倾斜摄影盘煤技术,分析了其各自的安装方式、特点以及适用的作业场合;总结了其共性的特点都是需要解算出煤场表面的三维坐标点云数据,才能生成煤场三维模型并进行储煤量计算;提出了在无法直接获得各个电厂盘煤系统的三维坐标点云数据的情况下,利用盘煤报告中煤场二维图像进行三维重构,或者利用煤场盘煤图像及库存量数据建立神经网络模型,进而对电厂煤量库存数据进行校核的进一步研究思路;对实现电厂存煤数据的有效和准确监管具有重要意义。In coal-fired power plants,how to timely inventory coal storage,in order to optimize the coal stock,and improve coal blending operation,and then carry out economic dispatch scientifically and reasonably,has always been an important topic.The traditional way of artificial method has big error,high cost and serious waste of resources.Ultrasonic measurement technology is greatly affected by time difference and dust.Measurement technology based on computer vision requires interpolation to fit the correction model.The above methods all have large measurement errors and have been eliminated by the market.This paper mainly introduces coal measuring technologies based on laser and uav tilt photography which have been researched and applied more recently.Their respective installation methods,characteristics and applicable working occasions are analyzed.They have the common characteristic that the 3d coordinate point cloud data of coal yard surface needs to be solved before the 3d model of coal yard can be generated and the coal storage amount can be calculated.In the case that the 3d coordinate point cloud data of coal yard of power plant cannot be obtained directly,3d reconstruction can be carried out by using 2d images of coal yard in coal report,or by using neural network model,and then the coal volume can be checked.This research idea is of great significance to realize effective and accurate supervision of coal storage in power plants.
