[0002] Dry-mixed mortar, also known as cementitious mortar, is a kind of granular or powdery material that is physically mixed with aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion, and is transported to a construction site in the form of bags or bulk, and can be directly used after being mixed with water.

[0003] Dry-mixed mortar has been developed and grown in the European construction market since the 1950s, and has been widely used in European countries for more than 40 years. Dry-mixed mortar has been used for external wall insulation for 35 years in Europe. Due to the outstanding advantages of dry-mixed mortar, such as water saving, energy saving, convenience, speed, environmental protection, and strong adhesion, dry-mixed mortar has rapidly swept the building material markets in Europe and the United States. Today, dry-mixed mortar is widely used as the main bonding material and external wall insulation material in developed Western countries and many developing countries around the world, and has also rapidly developed in Asia and other regions.

[0074] In one embodiment of the present application, the preset number of revolutions threshold is set to 30 r / min; that is, when the number of revolutions of the stirring device is greater than or equal to 30 r / min, it is determined that the stirring bin is in the first working condition, and the first working condition in this embodiment is that the stirring device stirs at a faster speed, or the stirring device has a tendency to stir quickly.

[0075] S123: If the number of revolutions is less than the preset number of revolutions threshold, it is determined that the stirring bin is in the second working condition.

[0076] In one embodiment of the present application, when the number of revolutions of the stirring device is less than 30 r / min, it is determined that the stirring bin is in the second working condition, and the second working condition in this embodiment is that the stirring device stirs at a slower speed, or the stirring device has a tendency to stop stirring.

[0077] S130: If the working condition information meets the image acquisition requirements, the video information of the material in the stirring bin is acquired by the plurality of image acquisition devices 2.

[0081] In one embodiment of the present application, when the stirring device stirs quickly or has a tendency to stir quickly, the driving pin shaft is driven to rotate by the activation driving member 13 to drive the rotating member 12 to rotate, so that the rotating member 12 covers the image acquisition device 2, thereby avoiding the mortar from being thrown onto the image acquisition device 2 by the stirring device when the stirring device stirs quickly, and affecting the normal acquisition function of the image acquisition device 2.

[0082] S132: If the stirring bin is in the second working condition, the protection device 1 is in a closed state, and the video information of the material in the stirring bin is acquired by the plurality of image acquisition devices 2.

[0083] In one embodiment of the present application, when the stirring device stirs slowly or has a tendency to stop stirring, the driving pin shaft is driven to rotate by the activation driving member 13 to drive the rotating member 12 to rotate, so that the rotating member 12 is opened to acquire the video information of the material in the stirring bin by the image acquisition device 2.

[0084] In the embodiment, the guard device 1 is in the closed state, i.e., the guard device 1 does not protect the image acquisition device 2.

[0085] S200: processing the video information to obtain the photo data.

[0086] In one embodiment of the present application, the guard device 1 is in the closed state, i.e., the guard device 1 does not protect the image acquisition device 2. Figure 6 S200 specifically includes the following steps.

[0089] S220: screening the video stream information of each frame of image to obtain the photo data of the material meeting the condition.

[0090] In one embodiment of the present application, the image screening tool is used to screen the video stream information of each frame of image, and thus the photo data of the material meeting the condition can be obtained.

[0091] By intercepting the video stream to obtain the video stream data and then screening the video stream data, the photo can be finally obtained, so that the completeness and clarity of the photo can be ensured.

[0092] S300: determining whether the material in the mixing bin is mixed uniformly according to the photo data.

[0093] In one embodiment of the present application, the guard device 1 is in the closed state, i.e., the guard device 1 does not protect the image acquisition device 2. Figure 7 S300 specifically includes the following steps.

[0094] S310: extracting the material mixing feature information according to the photo data, the material mixing feature information including the color of the mixed material and the uniformity of the particle size of the mixed material.

[0095] In one embodiment of the present application, the color feature and the particle size uniformity feature of the mixed material are extracted from the obtained photo, so as to prepare for the next step of determining whether the mixed material is mixed uniformly.

[0096] S320: if the color of the mixed material is within the preset reference color range and the uniformity of the particle size of the mixed material is within the preset particle size range, it is determined that the material in the mixing bin is mixed uniformly.

[0097] Wherein, the embodiment presets a reference color range and a particle size range, and then compares the color of the mixed material with the preset reference color range to determine whether the color of the mixed material is within the reference color range; compares the particle size of the mixed material with the preset particle size range to determine whether the particle size of the mixed material is within the particle size range; if both of the above are within the preset range, it can be determined that the mixed material in the stirring bin is uniform; if any one of the above is not within the preset range, it can be determined that the mixed material in the stirring bin is not uniform.

[0098] S400: If the mixed material in the stirring bin is not uniform, adjust the stirring time and stirring speed of the stirring device in the stirring bin.

[0099] Wherein, the length of the mortar mixing time will affect the uniformity of the mortar. If the mixing time is too short, the materials in the mortar may not be fully mixed, resulting in uneven particles in the mortar, which will cause uneven mortar during construction, affecting the construction effect; if the mixing time is too long, the materials in the mortar may be over-mixed, resulting in poor flowability of the mortar, which is difficult to construct.

[0100] Wherein, in an embodiment of the present application, when it is monitored that the mixed material in the stirring bin is not uniform, the stirring time or stirring speed of the stirring device can be adjusted to improve the uniformity of the mixed material.

[0101] S500: After stirring for a preset time, the video information of the material in the stirring bin is re-collected, and whether the mixed material in the stirring bin is uniform is judged again according to the video information until the mixed material in the stirring bin is uniform.

[0102] Wherein, in an embodiment of the present application, after the stirring time is extended, the video information of the material in the stirring bin is re-collected, and then whether the mixed material in the stirring bin is uniform is re-judged according to the video information. If it is uniform, stop stirring again; otherwise, if it is still not uniform, repeat the above steps in turn until the mixed material is uniform.
