[0054] The industrial computer includes an image processor and a detection controller. The image processor is in communication connection with the camera 84 and is used to analyze the image information of the concrete aggregate collected by the camera 84. Different amounts, different origins and different types of steel slag are added to natural sand or artificial sand to prepare standard samples, take photos, mark the steel slag, form a database and store it in the image processor. The image processor is trained by using an artificial neural network algorithm, so that a model for detecting and identifying steel slag in concrete aggregate is obtained in the image processor. When it is necessary to detect the aggregate sample, the image processor compares the model with the collected image information of the aggregate to make a judgment. Thus, whether the steel slag is mixed in the concrete aggregate can be rapidly detected, which is more accurate than the artificial visual identification method.

[0055] In an optional embodiment, the detection controller is in communication connection with the driving member 4, the vibration motor, the vibrator and the weight sensor. The detection method of the concrete aggregate includes the following steps.

[0059] When the weight sensed by the weight sensor reaches the set value, the detection controller controls the driving member 4 to control the sealing plate 5, so as to realize the closing of the coarse material outlet 13, and the vibrator is opened. Thus, the weight of the aggregate sample entering the detection area of the camera 84 is controlled, and the aggregate sample entering the detection area at a time can be controlled to be 20-50g.

[0060] S3, when the vibrator stops vibrating after completing the uniform paving of the concrete aggregate in the placing groove 321, the camera 84 transmits the image information of the surface of the concrete aggregate to the image processor for analysis and processing, so as to realize the detection of whether the concrete aggregate contains steel slag;

[0061] S4, after the test is completed, the result is viewed through the display screen 27;

[0062] S5, the sample after the test is taken out by pressing the material taking button 264 to open the collecting groove 14.

[0063] The display screen 27 is used to display the detection and recognition result. “OK” means that the concrete aggregate is qualified, i.e. no steel slag is contained therein; “NG” means that the concrete aggregate is unqualified, i.e. steel slag is contained therein, and the detection result is intuitive.

[0064] In another optional embodiment, the detection controller is in communication connection with the driving member 4, the vibration motor, the vibrator and the image processor. The detection method of the concrete aggregate comprises the following steps:

[0065] S1, the power is turned on, and the start button 262 is opened;

[0066] S2, the concrete aggregate sample to be detected is poured into the feeding hopper 111, the detection controller controls the vibration motor to start, and the image processor can analyze the shielding area of the concrete aggregate on the bottom surface of the placing groove 321. The detection controller controls the opening and closing of the coarse material outlet 13 according to the shielding area of the concrete aggregate on the bottom surface of the placing groove 321 detected by the image processor;

[0067] When the shielding area of the concrete aggregate on the bottom surface of the placing groove 321 does not exceed the set value, the detection controller controls the coarse material outlet 13 to be opened by controlling the driving member 4, so as to pour the concrete aggregate into the placing groove 321;

[0068] When the shielding area of the concrete aggregate on the bottom surface of the placing groove 321 exceeds the set value, the detection controller controls the coarse material outlet 13 to be closed by controlling the driving member 4, so as to stop pouring the concrete aggregate into the placing groove 321, and the detection controller controls the vibrator to be opened.

[0069] S3, when the vibrator stops vibrating after completing the uniform paving of the concrete aggregate in the placing groove 321, the camera 84 transmits the image information of the concrete aggregate surface to the image processor for analysis and processing, so as to realize the detection of whether the concrete aggregate contains steel slag;

[0070] S4, after the test is completed, the result is viewed through the display screen 27;

[0071] S5, press the material taking button 264 to open the collecting groove 14 and take out the sample after the test.

[0072] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
