Laser coal measurer

Abstract

The invention discloses a laser coal measurer comprising a laser mounted on the frame of a stacker-reclaimer, a data processor in signal connection with the laser, and a stroke controller in signal connection with the signal processor. An angle controller is fixedly connected with the laser and is used for controlling an intersection angle between the scanning plane and the vertical plane of the laser, and is in signal connection with the data processor. The data processor is used for calculating measurement data, automatically and rationally compensating a shaded part at the front end of a coal yard, generating a three-dimensional solid figure of the coal yard pile shape, and querying the volume and weight of a coal pile in segments.

Description

technical field [0001] The invention relates to a laser coal pan instrument. Background technique [0002] In order to accurately obtain the amount of coal stored in the power plant, the irregular coal pile was shaped with a coal pusher in the early stage, and then measured with a ruler to calculate the volume of the coal pile, and then multiplied by the specific gravity of the coal to obtain the amount of coal stored. This process is called For coal. However, this method has a large error in the measurement results. Using video imaging technology to measure pan coal, because it is a two-dimensional graphic and the color difference between the coal and the surrounding environment is not large, it is greatly affected by the natural environment such as climate and light, thereby reducing the measurement accuracy and reliability. At present, the laser pan coal measuring device is used to reduce the measurement error caused by human factors, and realize the automatic coal pan ...

Problems solved by technology

Among them, the portable laser pan coal meter is complex to operate and needs to manually select multiple measurement points for measurement, which takes a long time and has inaccurate measurement accuracy; while the fixed laser pan coal instrument cannot be moved because it is fixed, it is suitable for coal yards with complex coal piles. There are many blind spots that cause inaccurate measurement accuracy. In order to ensure that the accuracy meets the system requirements, two or more fixed laser pan coal detectors must be installed

Therefore, in order to solve the problem that the existing laser coal-panning scheme of the coal yard has large coal-panning errors and high cost, it is a challenge for those skilled in the art to design a coal-panning device with a high degree of automation, small errors, low cost, and safety. a technical problem
