Intelligent monitoring system for gravel aggregate quality

Abstract

The invention provides an intelligent monitoring system for gravel aggregate quality. The system comprises a fine aggregate monitoring unit, a coarse aggregate monitoring unit, a wireless communication module and a long-distance monitoring host, wherein the fine aggregate monitoring unit comprises a fine aggregate sampling component, a fineness modulus detecting module, a moisture content detecting module, a silt content detecting module, a first human-computer interaction interface and a first microprocessor module; the coarse aggregate monitoring unit comprises a coarse aggregate sampling component, an information collecting module, an image processing module, a second human-computer interaction module and a second microprocessor module. The intelligent monitoring system provided by the invention comprises two online monitoring systems for the gravel aggregate quality, and one system is used for performing intelligent online detection of fine aggregate quality indexes such as the fineness modulus, moisture content and silt content, and the other system is used for performing intelligent online detection of oversize-undersize content of coarse aggregate to substitute daily manual inspection in the laboratory, thereby improving accuracy and timeliness of quality tests of the existing aggregate processing system.

Description

technical field [0001] The invention belongs to the technical field of sandstone aggregate quality detection, and in particular relates to an intelligent sandstone aggregate quality monitoring system. Background technique [0002] Concrete is currently the largest man-made material and the most important building material. The most serious impact on the quality of concrete is the raw material, which is an urgent problem to be paid attention to to improve the concrete technology in our country and ensure the safety, durability and economy of buildings. [0003] The aggregate concrete system of sand and gravel in the construction of large-scale hydropower projects is one of the important links in the construction organization design, which affects the quality, safety and economic benefits of the entire project. As we all know, the role of sand and gravel aggregate in concrete is very important. It acts as a skeleton and transmits stress. Even without cement slurry, aggregate ...

Problems solved by technology

[0004] At present, the quality detection method of hydraulic concrete sand and gravel fine aggregate in China is manual experimental test. This method adopts the classification process of sampling first and then testing. The main test items include sand particle grading test and surface moisture content test. This detection is carried out "offline". There is a time lag between the sand particle gradation and surface moisture content detected by this method and the actual production state of concrete sand and gravel fine aggregate, so this detection method cannot be timely. Reflecting the instantaneous state value of production, production operators need to constantly adjust the ingredients of concrete sand and gravel aggregates according to the sampling test results, which cannot guarantee the production quality and efficiency of concrete sand and gravel aggregates
