Stock yard weight detection method and system

Abstract

A material field weight detection method. The method comprises arranging a pressure sensing device (2) on a foundation (7) of a material field, the pressure sensing device (2) being used for detecting the pressure on an action area in real time and converting the pressure into the weight of materials (1) on the material field. A material field weight detection system, comprising a pressure sensing assembly (2) arranged on a foundation (7) of a material field, the pressure sensing assembly (2) being used for detecting the pressure on an action area in real time and converting the pressure into the weight of materials (1) on the material field. The method and system have advantages of simple principle, convenient operation, high stability and precision, wide application range, and high efficiency.

Description

technical field [0001] The invention mainly relates to the field of inventory monitoring equipment, in particular to a method and system for dynamic stock monitoring based on pressure sensing. Background technique [0002] For warehousing, logistics and other fields, how to monitor inventory in real time is a crucial issue, especially for monitoring the inventory of some irregular materials, so far there has not been a suitable method. For example, large-scale artificial sand and gravel stockyards, port warehouses, artificial piles, etc., due to their huge size, cannot use conventional detection methods to achieve manual weighing of stockyards, which brings inconvenience to freight yard management. [0003] Taking the coal-fired inventory management of power plants as an example, it is of great importance to take stock of the coal-fired inventory of power plants as a link in the entire fuel management system. People have been looking for a way to accurately obtain the amoun...

AI Technical Summary

Problems solved by technology

However, the existing laser pan coal measuring device also has the following deficiencies: 1. Low precision

In terms of calculation, although the error of the calculated volume model can be ignored, there is also a large systematic error in the estimation of the density of the measured coal pile

Since the whole system integrates all the above subsystem errors, it directly leads to the problem of low accuracy of the traditional laser pan coal device.

Therefore, many power plants found that after buying the laser coal counting instrument, they found that the accuracy of the actual counting results was far below the nominal accuracy value of some manufacturers.

2. Low reliability

The working process of the traditional laser coal panning instrument is relatively complicated, including coal pile point picking (including distance measurement, direction angle measurement, vertical angle measurement), data conversion (conversion to three-dimensional coordinates), three-dimensional modeling, volume calculation links, cumbersome The working process leads to low reliability

3. Low adaptability

The propagation of laser in the air in rain, snow, dust and smog is easily affected, which will affect the measurement of points, distances, angles, etc.

Therefore, the measurement results of the laser pan coal meter are very unreliable under the above environmental conditions, and the environmental adaptability is not high.

4. Low efficiency

The above two points will lead to the prolongation of the whole coal-panning process, which will make the working efficiency of the coal-panning instrument low.
