Embodiment Construction

[0056] The specific embodiment of the present invention is as figure 1 , figure 2 shown.

[0057] The coal piles 3 to be coaled in the power plant are stacked on the coal yard 10, and the rectangular area of ​​the coal yard 10 has a length of l and a width of w. The vertical bisector of the width of the coal yard is the partition line 14, along which the rectangular area is divided into two areas of equal width w / 2, the left area and the right area.

[0058] The automatic coal pan system is composed of a computer 9, a wireless switch 7, a wireless local area network networking of the left area measurement system 1 and the right area measurement system 2. The measurement system 1 in the left area is exactly the same as the measurement system 2 in the right area. They consist of the first guide rail 1-1 and the second guide rail 2-1, the first sliding platform 1-2 and the second sliding platform 2-2, the first numerical control electromechanical box 1-3 and the second numeri...

Abstract

The invention discloses a wireless network symmetrical laser ranging-based automatic coal checking method for a power plant. The wireless network symmetrical laser ranging-based automatic coal checking method for the power plant adopts a system which is formed by a computer, a wireless switch, a measuring system and a wireless local area network; the measuring system comprises a left area measuring system and a right area measuring system which are formed by guide rails, sliding platforms, numerical control electromechanical boxes, scanning ranging electromechanical boxes, rotary shafts, laser ranging machines, bases, fixedly installed bolts, numerical control electromechanical box wireless access points and scanning ranging electromechanical box wireless access points. The sectional area is obtained by adding the sectional area of a left partition and the sectional area of a right partition; the volume of a coal heap is calculated by accumulating layered volume elements. According to the wireless network symmetrical laser ranging-based automatic coal checking method for the power plant, a right and left partition symmetrical synchronous laser ranging chromatographic volume calculation method is adopted, dead angles are easy to eliminate, and the coal checking speed is improved; the measuring system is fixedly installed, the left area and the right area are subjected to synchronous control and data analysis through the wireless network, full-automatic coal checking of the power plant is achieved, and the disadvantage that a conventional coal checking instrument requires professionals to operate and use is overcome.

Description

technical field [0001] The invention relates to a fully automatic power plant coal-coaling method, which adopts a wireless network symmetrical laser ranging method and belongs to the technical field of photoelectric testing. Background technique [0002] Coal is needed for thermal power generation. With the expansion of thermal power plant units and the increase of coal price, pan coal has increasingly become an indispensable part of power generation enterprises. The so-called pan coal refers to the amount of coal stored in the thermal power plant's inventory. The initial method of coal panning is manual coal panning, that is, the accumulated coal is first shaped into a relatively regular trapezoid or rectangle by a bucket wheel stacker-reclaimer (the carrier used to stack coal). Then manually use a tape measure to measure, and then calculate the volume according to the calculation and then obtain the weight according to the density. This method is time-consuming, labor-in...
