Monitoring device of premixed concrete and monitoring method of monitoring device

Abstract

The invention discloses a monitoring device of premixed concrete and a monitoring method of the monitoring device. The monitoring device comprises a stirring device, a dust concentration sensor arranged in the stirring device, a dust collection device, a video monitoring system and a control system, wherein the control system comprises a data storage system and an image analysis system, the data storage system stores a database of relations between the images and slumps of the premixed concrete, and the image analysis system analyzes the similarity between real-time monitored images and the images prestored in the data storage system in real time to obtain predicted slumps corresponding to the real-time monitored premixed concrete. The monitoring method includes the steps of preparing rawmaterials, stirring the raw materials and the collecting dust, shooting the real-time images and analyzing the similarity and displaying the predicted slumps on a display screen. By using the monitoring device and the monitoring method, the predicted slump value can be displayed in real time so as to adjust the premixed concrete in time and the waste of resources and economic losses caused by thequality failing to meet the design requirements after unloading are avoided.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a monitoring device and a monitoring method for ready-mixed concrete. Background technique [0002] Ready-mixed concrete is the concrete that is produced in the mixing plant, sent to the place of use by transportation equipment, and delivered as a mixture. The workability of ready-mixed concrete has an important impact on the concrete's constructability, mechanical properties, structural durability and long-term performance. The workability of ready-mixed concrete includes fluidity, cohesion and water retention. Among them, fluidity is mainly reflected by slump, and cohesion and water retention are usually judged qualitatively by observation. [0003] Ready-mixed concrete is affected by many factors, resulting in large fluctuations in workability in the actual production process, and problems such as bleeding and segregation are prone to occur, seriously affecting the construct...

Problems solved by technology

[0003] Ready-mixed concrete is affected by many factors, resulting in large fluctuations in workability in the actual production process, and problems such as bleeding and segregation are prone to occur, seriously affecting the constructability, mechanical properties, and structural durability of ready-mixed concrete.

However, it is difficult to effectively monitor its working performance during the concrete mixing process, and it is difficult to predict whether the working performance of the concrete mixture meets the construction requirements.

[0004] If it is found during unloading that the workability of the ready-mixed concrete does not meet the construction requirements, it will be difficult to make adjustments, or even scrapped, which will result in a large waste of resources and economic losses
