Silo material weighting system and method based on distributed weighing nodes

Abstract

The invention discloses a silo material weighting system and a method based on the distributed weighing nodes, belongs to the technical field of weighting, and is characterized in that: a plurality ofweighing nodes mutually separated are provided at the bottom of the silo; each of the weighing nodes comprises a weighing sensor, a communication transceiver, and a power supply; the communication transceiver is connected with the data transceiving center; the data transceiving center is connected with the data processing center; and the communication mode between the weighing nodes and the datatransceiving center is wireless communication or wired communication. The existing technical problem that the weight of the silo material cannot be effectively weighted is solved, and the system and the method are mainly applied to the technical field of the silo material.

Description

technical field [0001] The invention belongs to the technical field of weight measurement, and in particular relates to a system and method for measuring the weight of silo materials based on distributed weighing nodes, in particular to a system device and a measurement method for measuring the weight of materials stored in large silos. Background technique [0002] In grain, oil, chemical, food, feed and other industries, large-scale silos are used for material storage. These silos are often dusty, require high explosion-proof requirements, and have a huge space. Thousands of tons, or even tens of thousands of tons of materials are stored. But at present, there is no better way to accurately measure the weight of the materials stored in these silos, which has caused problems such as poor management of many enterprises, loss of materials, and unclear accounts. At present, the method used to measure the weight of large silos is to set several observation ports from the top of...

Problems solved by technology

When the surface of the material is undulating, this method often has a large measurement error; using laser radar to scan the surface of the material in a rotating dot matrix, and performing trigonometric function conversion, can also obtain a three-dimensional map of the material, but the cylinder during the operation The warehouse is often dusty, causing inaccurate laser ranging; microwave radar can also be used for ranging, using rotating dot matrix scanning to obtain the ranging results of the material surface, and performing three-dimensional reconstruction to obtain the volume and weight. The radar lock time is relatively slow, and it takes up to 10 seconds to measure the distance of a point. Therefore, it often takes more than 15 minutes for a single microwave radar to obtain a three-dimensional shape of a material (such as scanning 100 points on the surface of the material). In addition, high-precision microwave Radar is often expensive, but the ranging accuracy is limited, and the mechanical structure that controls the microwave radar to perform rotary scanning will also increase the ranging error; using microwave beam reflection and other technologies, it is possible to control the microwave radar to rotate without a mechanical structure Scanning, but the equipment using this technology is expensive at present, and the accuracy is limited, and the general error is more than 3%
