Description

Technical Field

[0001] This application relates to the field of concrete processing technology, and in particular to a video monitoring method, system, terminal and storage medium for concrete mixing. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials (cement), granular aggregates (also known as aggregates, including sand and gravel), water, and, if necessary, admixtures and additives (such as fly ash) in a certain proportion, uniformly mixing, compacting, and curing.

[0003] Currently, in order to protect the health of construction workers and the environment of construction sites, concrete mixing and processing have been largely standardized at batching plants. In the concrete processing operations at the batching plant, materials such as sand, gravel, cement, water, and admixtures are weighed in hoppers and then fed into the mixing bins in a certain material ratio for thorough mixing. The thoroughly mixed concrete is then transported to the construction site by mixer trucks and pumped to the pouring location. During transportation, the mixing drums carrying the concrete are kept rotating to prevent the concrete from hardening, segregation, or other phenomena.

[0004] Concrete used in existing construction projects often dries out during transportation due to moisture evaporation. It needs to be diluted with water before it can be used. However, the uniformity of the concrete after adding water is poor, and the uneven dilution caused by the rotation of the mixing drum reduces the effectiveness of the concrete and affects the quality of the building. Summary of the Invention

[0025] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0028] This application provides a video monitoring method for concrete mixing, the main process of which is described below.

[0029] like Figure 1 As shown: Step S101: Obtain concrete transportation information.

[0030] In this embodiment of the application, the concrete transportation information includes transportation time and mixer truck data; wherein, the transportation time refers to the time required for the mixer truck to travel from the mixing plant to the construction site, and the transportation time is obtained by taking the average of the transportation test times from multiple transportation tests; the mixer truck data includes the specification information and rotation information of the mixing drum used to load concrete on the mixer truck; the specification information refers to the inner diameter of the mixing drum and the rated concrete loading capacity; the rotation information refers to the rotation speed of the mixing drum.

[0031] Step S102: Determine the concrete material mix ratio based on the concrete transportation information and the concrete demand information.

[0032] In this embodiment of the application, based on the above concrete transportation information, the moisture loss of concrete during transportation is analyzed. Then, combined with the material ratio requirements of the construction project for concrete, a new material ratio is updated to make up for the moisture loss during transportation and reduce the amount of water required for dilution at the end of concrete transportation.

[0033] Specifically, firstly, based on the pouring task of the building project, the concrete demand information is obtained; it is understood that during the construction of a building project, the required concrete material ratio will vary for different building structures and different building locations; in this embodiment of the application, the required concrete ratio is determined based on the specific pouring task.

[0034] Next, based on the specifications and rotation information of the mixing drum obtained in step S101, the rate of water evaporation from the concrete during transportation is analyzed. The contact area between the concrete and air in a static state is easily obtained using the inner diameter of the mixing drum and the rated concrete load. Then, the contact area between the concrete and air in a rotating mixing state is obtained using the rotation speed of the mixing drum, combined with the shape and specifications of the mixing blades inside the drum. It is understood that because the concrete flows with the mixing blades in a rotating mixing state, the contact area is definitely greater than that in a static state. The contact area between the concrete and air in a rotating mixing state is approximated using fluid physics. Then, based on the contact area between the concrete and air in a rotating mixing state, combined with the humidity and temperature of the gas inside the mixing drum and the concrete temperature, the rate of water evaporation from the concrete is easily obtained. It is understood that due to the structural constraints of the mixing drum, the airflow inside and outside the mixing drum is not high; therefore, the influence of wind on water evaporation is not considered here.

[0035] Finally, based on the transportation time and the concrete moisture evaporation rate, the concrete moisture evaporation amount is calculated. Based on the concrete moisture evaporation amount, the water supply of the mixing plant during concrete processing is increased accordingly on the basis of the required mix proportion, and the final concrete material mix proportion scheme is determined.

[0036] Step S103: Based on the concrete material mix design, analyze and obtain the concrete state information.

[0037] In this embodiment of the application, based on the above concrete material ratio, the concrete mixing process simulation technology is used to analyze and obtain the state image of the concrete mixture when the concrete is uniformly mixed, and to analyze and obtain the state image of the concrete mixture within a time range greater than or equal to the transportation time after the uniform mixing time point; wherein, the concrete mixing process simulation technology adopts existing related technologies.

[0038] Step S104: Obtain real-time data related to the mixing status in the mixing chamber.

[0039] In this embodiment of the application, the real-time data related to the mixing status in the mixing chamber includes concrete material metering data and real-time images of the concrete mixture; the concrete material metering data is obtained through the metering chamber, and the real-time images of the concrete mixture are acquired through relevant video monitoring equipment.

[0040] Step S105: Generate a concrete mixing report based on the concrete state information and real-time data related to the mixing state in the mixing chamber.

[0041] In this embodiment of the application, after obtaining real-time data related to the mixing status in the mixing chamber, the concrete material metering data and the concrete material proportion are first matched. When the proportion shown by the concrete material metering data does not meet the concrete material proportion, the required materials and their metering are analyzed, and a material replenishment report is generated. Workers can replenish materials in a timely manner according to the material replenishment report, thereby improving the mixing effect of concrete and improving the quality of concrete. When the proportion shown by the concrete material metering data meets the concrete material proportion, the mixing operation of the mixing chamber is started.

[0042] Next, based on the real-time images of the concrete mixture, the distribution of sand and gravel in the mixing chamber is processed and analyzed, and the grayscale color of the mixture in the mixing chamber is identified. When the sand and gravel are approximately evenly distributed and the grayscale color of the mixture is basically consistent, it is determined that the concrete is mixed evenly. At this point, the mixing operation in the mixing chamber is stopped.

[0043] Then, by comparing the real-time image of the concrete mix under uniform mixing conditions with the initial image of the concrete mix state described above, the approximation of the two images is analyzed, and a concrete mix state report under uniform mixing conditions is generated. This report helps staff understand the mixing status of the concrete and the uniformity of the concrete mixing, and the uniformity is equal to the aforementioned approximation.

[0044] In this embodiment, a video monitoring method for concrete mixing further includes acquiring real-time data related to the mixing state inside the mixing drum, specifically manifested as a real-time image of a second concrete mix. Then, based on the color grayscale of the real-time image of the second concrete mix, the concrete moisture content is analyzed, where the moisture content is positively correlated with the water content ratio. Simultaneously, based on the transport time of the mixer truck, the real-time image of the second concrete mix is ​​compared with the concrete mix state image at the corresponding time, and the similarity between the two images is analyzed to generate a second concrete mixing report. This allows workers to monitor the concrete state during transport in real time. Furthermore, upon arrival at the construction site, the second concrete mixing report and the real-time image of the second concrete mix can be used to confirm whether the concrete requirements for the pouring task are met, further improving the quality of the building.
