Background
At present, coal coiling is an indispensable link of a thermal power plant from the beginning. The traditional coal yard inventory mode is as follows: before inventory, a coal pusher is used for roughly shaping a yard, then all departments of a power plant organize manual work to obtain rough length, width and height data of the coal yard in a tape-drawing mode, rough graphs are drawn manually, and reports are made. Portable coal jiggers have emerged later: and manually dotting by using a single-point laser range finder to obtain profile data of the coal pile, and transmitting the profile data to a computer. And the coal inventory software carries out relative coordinate conversion on the original data by setting a reference point, a free observation point or a fixed observation point to generate a coal pile profile graph and calculate the volume of the coal pile. With the development of industrial measurement hardware and the development of computer graphics technology, a coal inventory system based on fixed installation and a laser section scanning mode is generated, and the coal inventory system has the characteristics of fixed installation, dense sampling points, high automation degree and high accuracy. Therefore, compared with any other inventory mode and equipment, the fixed coal inventory system has great advantages in reliability, accuracy and automation degree, and is the most advanced large bulk material yard measurement mode. And the characteristics of the fixed coal inventory system can well provide stable and reliable field basic data for a digital coal yard. Through the real-time wireless transmission of coal inventory data, the coal piling and taking positioning technology of the bucket wheel machine is combined, the data is called and interacted with the fuel management system, and related management departments can master different coal quantities and various coal indexes of the coal piles in the field subareas in real time. In this sense, the fixed coal inventory system can well manage the site of a coal yard and guide the blending combustion of coal, and has important values for the management of a power plant and the energy conservation and the efficiency improvement.
The existing fixed coal coiling technology mainly comprises two types: the first one is to install laser scanner at bucket wheel machine big arm front end unilateral, and the shortcoming is the laser scanner of unilateral installation, and at the dish coal in-process, the opposite side in place can't scan, thereby this scheme has the blind area in the opposite side and can't reach full dish coal effect. The second is to install laser scanner at the top of coal yard rack, and the shortcoming needs many measuring equipment to build the net, and the price is expensive, and general coal inventory cycle takes day as the cycle simultaneously, can not realize bucket wheel machine in the operation process, the local real-time change that detects the coal pile.

(2) The coal coiling device is expensive, and the real-time change of the coal pile can not be locally detected in the operation process of the bucket wheel machine.
The difficulty in solving the above problems and defects is: how to realize fast, accurate and dead-angle-free coal coiling under the condition of saving cost. This requires a great deal of technical experience and processing it is a difficult and complex task.
The significance of solving the problems and the defects is as follows: laser scanners have all been installed to this scheme in big arm both sides, have solved first scheme because of the unable problem that has the blind area of scanning of opposite side. In the second solution, the first solution is more cost-effective than the second solution because the scanner lens is more expensive. Meanwhile, the laser scanner is arranged on the large arm, so that the problem of the real-time change of the local detection coal pile in the second scheme can be solved.
