Problems solved by technology

[0003] In the related art, the mixing plant for producing asphalt concrete and cement concrete is usually equipped with an aggregate bin, and the outlet of the aggregate bin is generally provided with a large and a small door, and the aggregate is realized by opening and closing the large and small doors, respectively. coarse and precise, but the cost of the structure is high
If a single-door structure is adopted, the cost can be reduced. However, since the weighing of aggregates is greatly affected by factors such as aggregate storage capacity and door opening, the single-door structure cannot take into account both the speed and accuracy of aggregate weighing.

Embodiment 1

[0056] This embodiment provides a method for weighing materials in a silo. The bottom of the silo 100 is provided with a silo door 110 for controlling the falling of materials in the silo 100 and a weighing device for weighing the materials falling through the silo door 110 120.

[0057] like figure 1 As shown, the weighing method of silo material includes the following steps:

[0058] Step S10, establishing a database, the database is provided with several weighing target values ​​with different numerical values ​​and several warehouse door opening duration values ​​corresponding to each weighing target value one-to-one;

[0059] In step S20, the total target value to be weighed is obtained, and when the total target value to be weighed is less than or equal to the largest weighing target value in the database, the total target value to be weighed is used as the fine weighing value, and the process goes to step S50, When the total weighing target value is greater than the l...

Embodiment 2

[0074] like figure 2 As shown, this embodiment provides a method for weighing materials in a silo. In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features.

[0075] The weighing method of the material in the silo also includes the following steps:

[0076] Step S70, according to the difference between the actual weight value of the material dropped through the warehouse door in step S40 and the weighing target value, correct the warehouse door opening duration value corresponding to the weighing target value in the database.

[0077] The purpose of this embodiment is to adjust the opening time value of the warehouse door according to the weighing and feeding situation. The difference between the actual weight value and the weighing target value represents the progress of the feed weighing. If the difference between the actual weight value and the weighing target value is large, the door openi...

Embodiment 3

[0079] like image 3 As shown, this embodiment provides a method for weighing materials in a silo. In addition to the technical features of the above-mentioned embodiments, this embodiment further includes the following technical features.

[0080] Step S70 specifically includes:

[0081] Step S702, obtaining the difference between the actual weight value and the weighing target value;

[0082] Step S704, through the following formula, correct the current warehouse door opening duration value according to the difference, so as to obtain the corrected warehouse door opening duration value: After the correction, the warehouse door opening duration value=current warehouse door opening duration value+first weighting coefficient×( Difference value / Weighing target value)×current door opening time value.

[0083] This embodiment provides a specific correction method for correcting the opening duration value of the warehouse door. Among them, the first weighting coefficient can be ...

Abstract

The invention provides a stock bin material weighing method, a stock bin, a stock bin material weighing method device and a computer readable storage medium. The bottom of the stock bin is provided with a bin door controlling falling of materials in the stock bin and a weighing device used for weighing the materials falling through the bin door. According to the stock bin material weighing method,coarse weighing and multi-stage fine weighing are conducted on materials according to the size relation between the total target value to be weighed and the weighing target value. The warehouse material weighing method provided by the invention is high in weighing efficiency and high in weighing accuracy, so that the production efficiency is improved, and the labor cost in the production processis saved.

Description

technical field [0001] The present invention relates to the technical field of weighing, and in particular, to a method, a silo, a device and a computer-readable storage medium for weighing materials in a silo. Background technique [0002] Asphalt concrete and cement concrete are commonly used materials in road construction and building construction, respectively. Asphalt concrete and cement concrete are obtained by mixing and mixing various raw materials such as aggregate, powder and other additives. In the preparation process of the above materials, various types of aggregates used need to be weighed. [0003] In the related art, the mixing plant for producing asphalt concrete and cement concrete is usually provided with an aggregate silo, and the discharge port of the aggregate silo is generally provided with large and small silo doors. The rough and fine scales of the structure are high, but the cost of this structure is high. If the single-door structure is adopted,...
