Method, device and control system for judging homogeneity of concrete mixing

Abstract

The invention relates to the technical field of engineering equipment, and discloses a judgement method for concrete stirring homogeneity. The judgement method includes the steps that a homogeneous current sample library is established; image samples during concrete stirring are collected, and whether stones in concrete are distributed uniformly or not is judged through the image samples; in the case of judging homogeneous distribution of the stones in the concrete, current values of a stirring motor in a preset time period are continuously collected, and the average current value of the stirring motor in the preset time period is calculated; and according to selection rules, corresponding homogeneous currents are selected from the homogeneous current sample library, the average current value is compared with the homogeneous currents, and whether concrete stirring meets the requirements of homogeneity or not is judged according to the comparison results. whether concrete stirring meetsthe requirements of homogeneity or not is judged synthetically through image identification and homogeneous currents, the errors caused by singly adopting image identification or singly adopting thehomogeneous currents to judge the homogeneity are made up for, the quality consistency of discharged concrete is guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a method and device for judging the uniformity of concrete mixing, and a concrete mixing control system. Background technique [0002] Concrete, also known as "concrete", is a kind of artificial stone made of cementitious materials, aggregates, water, and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. In the process of concrete mixing, the homogeneity of mixing has a significant impact on the workability of fresh concrete and the mechanical properties and durability of hardened concrete. Concrete mixing homogeneity refers to the uniformity of the distribution of each raw material component in concrete. When mixing concrete, the mixing machine cannot automatically judge whether the mixed concrete meets the homogeneity requirements. The traditional method is to rely on the operator to observe ...

Problems solved by technology

Therefore, only using the distance between the pixel areas of coarse aggregate to judge the uniformity of concrete has a large error, which has limitations and is not suitable for concrete with complex component materials.
