The invention discloses a method and device for monitoring the state of concrete in a mixer truck based on voice recognition, and the device comprises a processor, a pickup, a preprocessing module, and a storage unit, wherein the pickup is fixedly installed in a mixer truck tank body, the pickup is connected with the processor through the preprocessing module, and the processor is connected with the storage unit. According to the invention, the original sound signal of the concrete state in the mixer truck collected by the sound pickup is utilized, the concrete state is quickly judged throughsound recognition, an operator does not need to test and monitor the concrete state in real time, the real-time judgment of the concrete state in the mixer truck is realized, the quality of a concretemixture is improved, pumping construction is guaranteed, engineering quality risks are reduced, and production efficiency is improved.
Description
technical field [0001] The invention relates to a method and device for monitoring the state of concrete in a mixer truck based on sound recognition, and belongs to the technical field of intelligent recognition. Background technique [0002] Concrete has become the most widely used building material in the construction field. However, due to the large fluctuations in the quality of concrete raw materials, especially the lack of supervision of the quality of sand and stone, the state of the concrete mixture changes greatly from the mixing station to the construction site. After arriving at the site, construction workers add water at will, resulting in fluctuations in the final concrete quality. . In order to avoid the above problems, the mixing plant is required to send front-field technicians to conduct random inspections on the concrete on site. On the one hand, the performance indicators of the mixture are fed back to the quality control personnel of the mixing plant as ...
