In the embodiment of the present invention, the specific shape of the sampling member 12 is not limited as long as the gripping and containing of the aggregate can be achieved.
The aggregate sample contains a large amount of dust, and when the moisture content of the aggregate sample is high, the dust is coagulated into a dough shape to form larger particles. The method has the advantages that the calculation of aggregate quality can be carried out by taking larger particles formed by dust as aggregates in image analysis, the aggregate samples need to be dehydrated before the images of the aggregate samples are collected in order to avoid the influence of dust agglomeration on the aggregate quality, and the aggregate samples are guaranteed to be sufficiently dry.
In practical applications, the dewatering unit 13 may employ a heater.
The controller 11 is connected with the conveying part 14 and is used for controlling the conveying part 14 to uniformly and dispersedly transmit the dehydrated aggregate samples to the image acquisition area so that the aggregate samples are in a thin curtain shape when falling into the image acquisition area.
In the embodiment of the invention, the particles in the aggregate sample are analyzed by adopting a mode of dynamically acquiring the aggregate image.
The conveying component 14 is mainly used for ensuring that particles in the aggregate sample can be uniformly dispersed and presented in the image acquisition area, so that the aggregate particles in the digital image acquired by the image acquisition component 15 can be uniformly distributed, and the accuracy of image analysis is improved.
In practical applications, the conveying member 14 may adopt a combination of the conveying groove 141 and the electromagnetic vibrator 142. The dewatering unit 13 may transfer the aggregate sample after dewatering treatment to the transfer chute 141 through the receiving hopper.
Fig. 2 is a schematic diagram of the structural components of an aggregate detecting device according to an embodiment of the present invention, in fig. 2, the conveying component 14 is exemplified by a conveying groove 141 and an electromagnetic vibrator 142, and an inlet of the conveying groove 141 is used for receiving an aggregate sample after dehydration treatment through a receiving hopper; the outlet of the transfer slot 141 is vertically aligned with the image capture area; the electromagnetic vibrator 142 is disposed at the bottom side of the transfer groove 141, and is used for uniformly and dispersedly transferring the dehydrated aggregate sample on the transfer groove 141.
The electromagnetic vibrator 142 uniformly disperses the aggregates on the conveying trough 141 by means of vibration, thereby ensuring that the aggregates output from the outlet of the conveying trough 141 can be in a curtain shape in the image acquisition area.
In practical application, the vibration intensity of the electromagnetic vibrator 142 can be controlled through frequency conversion, and the aggregate sample is ensured to be in a thin-screen shape when falling into an image detection area.
The image acquisition part 15 is arranged on the side of the image acquisition area and is used for acquiring a digital image of the aggregate sample.
In order to achieve effective acquisition of the digital image of the aggregate sample, the controller 11 may be connected with the image acquisition part 15, and when the controller 11 controls the operation of the conveying part 14, the image acquisition part 15 may be simultaneously controlled to start taking the digital image of the aggregate sample.
The image pickup section 15 is installed in such a position that its field of view covers the entire width of the blanking end of the transfer chute 141 so that each particle can be photographed. The installation height of the image acquisition component 15 can be adjusted according to the height of the blanking end of the transmission groove 141 so as to ensure the imaging quality in the detection process.
The controller 11 is mainly used for controlling the operations of opening and closing of the sampling part 12, the dehydrating part 13, the conveying part 14, the image acquisition part 15 and the like. The controller 11 may employ a Programmable Logic Controller (PLC).
In the embodiment of the present invention, the weighing unit 16 may directly weigh the dehydrated aggregate sample to obtain the sample mass; the weighing component 16 may also be arranged at the lower side of the image acquisition area for weighing the aggregate sample to obtain the sample mass of the aggregate sample.
The weighing part 16 may be composed of a hopper body carrying the aggregate sample and a load cell provided at the bottom of the hopper body.
Considering that the aggregate samples carried by the weighing part 16 need to be cleaned in time, in order to realize the automatic cleaning of the aggregate samples, in the embodiment of the present invention, the weighing part 16 may be composed of a bucket body 161 with an upper opening and a lower opening, a weighing sensor 162, a turning plate 163 and a cylinder 164.
The turning plate 163 is arranged at the bottom of the bucket body 161 and is in sealing connection with the bottom of the bucket body 161. The air cylinder 164 is connected with the turning plate 163 and used for controlling the turning plate 163 to move, so that the bottom of the bucket body 161 is conducted, and the aggregate samples in the bucket body can be rapidly and automatically discharged.
Because the movable turning plate 163 is arranged at the bottom of the hopper body 161, in practical application, the weighing sensor 162 can be arranged on the side wall of the hopper body 161 for weighing the sample mass of the aggregate sample in the hopper body.
In specific implementation, the weighing sensor 162 may be disposed behind the sidewall of the hopper body 161, and the weighing parameters of the weighing sensor 162 are adjusted in a weight correction manner, so as to ensure that the weighing sensor 162 can accurately measure the actual mass of the aggregate sample in the hopper body 161.
The user terminal 17 is respectively connected with the image acquisition part 15 and the weighing part 16 and is used for carrying out aggregate analysis on the digital image transmitted by the image acquisition part 15 so as to calculate the aggregate mass of the aggregate sample; and calculating the powder content of the aggregate sample according to the mass of the aggregate and the mass of the sample.
Assuming that the aggregate mass obtained by image analysis is m1 and the sample mass obtained by weighing is m2, the powder content of the aggregate sample is (m2-m1)/m2 × 100%.
The user terminal 17 may be a terminal device used by a manager, such as a PC or a mobile phone.
By analyzing the digital image of the aggregate sample, the characteristic parameters of the aggregate sample can be obtained. The characteristic parameters include various parameter types, and the powder content is one of all the characteristic parameters.
In a specific implementation, the user terminal 17 may pre-process the digital image, and calibrate the pre-processed digital image by taking a pixel as a unit, so as to calculate the characteristic parameters of the aggregate sample.
The characteristic parameters may include, among others, the powder content, fineness modulus, number of particles, average circularity, average aspect ratio, minimum particle size, maximum particle size, and particle size distribution map of the aggregate sample.
The preprocessing of the digital image mainly carries out noise reduction and filtering processing on the digital image. In a particular implementation, gaussian filtering may be employed to denoise and filter the image.
And binarizing the noise-reduced and filtered image by adopting a maximum interval variance method, automatically identifying sand particles, and forming a plurality of connected regions which can be labeled in sequence.
In order to improve the segmentation effect and improve the segmentation accuracy, a watershed segmentation algorithm and a distance transformation algorithm can be further adopted to solve the over-segmentation problem in the process of cutting the sand-bonded particles.
Obtaining the long diameter and the short diameter of the sandstone particles with the diameter of more than 75 microns by adopting a Feret diameter principle; fitting the obtained minor axis into an ellipsoid, and calculating the volume of a single particle; and after the detection is finished, fitting the particle quality of each gradation interval again through a compensation algorithm, thereby obtaining the aggregate quality of the aggregate sample.
The long diameter, the short diameter, the volume and the mass of each particle in the aggregate sample can be obtained through image analysis, and the particle number, the average circularity, the average length-diameter ratio, the average fineness modulus, the minimum particle size, the maximum particle size and the particle size distribution diagram can be counted on the basis of the volume, the volume and the mass.
According to the technical scheme, the aggregate detection device comprises a controller, a sampling component, a dehydration component, a transmission component, an image acquisition component, a weighing component and a user terminal. The controller is respectively connected with the sampling component and the dehydration component and is used for controlling the sampling component to obtain an aggregate sample from the aggregate conveyor belt; and controlling the dehydration part to perform dehydration treatment on the aggregate sample. Through dehydration treatment, the situation that dust in the aggregate is agglomerated can be effectively avoided. The controller is connected with the conveying part for the aggregate sample after control conveying part will dewater transmits to image acquisition region evenly dispersed, so that the aggregate sample is the curtain form when falling into image acquisition region, thereby makes the distribution of aggregate more even in the digital image of gathering, has promoted image analysis's accuracy. The image acquisition component is arranged on the side of the image acquisition area and is used for acquiring a digital image of the aggregate sample; the weighing part is arranged at the lower side of the image acquisition area and is used for weighing the aggregate sample to obtain the sample mass of the aggregate sample; the user terminal is respectively connected with the image acquisition part and the weighing part and is used for carrying out aggregate analysis on the digital image transmitted by the image acquisition part so as to calculate the aggregate mass of the aggregate sample; and calculating the powder content of the aggregate sample according to the mass of the aggregate and the mass of the sample. This aggregate detection device passes through the mode that image analysis and weighing combined together, and fine sand runs off when the effectual filter screen that has solved removes dust, causes the problem that the powder content rate deviates to appear for the powder content rate of the aggregate sample that calculates is more accurate.
In order to understand the characteristics of the aggregate sample more comprehensively, the aggregate detecting device 1 may further include a moisture content detecting unit 18 for acquiring the moisture content of the aggregate sample.
In practical applications, the moisture content detection unit 18 and the sampling unit 12 may be disposed together, for example, the moisture content detection unit 18 may be disposed at a side of the sampling unit 12.
After the sampling part 12 obtains the aggregate sample, the controller 11 may control the moisture content detection part 18 to detect the moisture content of the aggregate sample. Accordingly, the moisture content detecting part 18 may transmit the detected moisture content of the aggregate sample to the controller 11.
In order to evaluate whether the moisture content of the aggregate sample exceeds the standard, a preset threshold value can be set. And when the moisture content of the aggregate sample exceeds a preset threshold value, the moisture content of the aggregate sample exceeds the standard, and the aggregate sample needs to be dehydrated to avoid dust agglomeration.
In a specific implementation, the controller 11 may be connected to the dewatering component 13, and when the moisture content of the aggregate sample exceeds a preset threshold, the dewatering component 13 is controlled to dewater the aggregate sample.
In the schematic diagram shown in fig. 2, the connection relationship between the controller 11 and the sampling unit 12, the moisture content detection unit 18, and the dehydration unit 13 is shown by broken lines.
In order to improve the dewatering efficiency of the aggregate sample, a stirring member may be provided. The stirring member may stir the aggregate sample at the time of dehydration treatment of the aggregate sample and transfer the dehydrated aggregate sample to the conveying member 14.
In the embodiment of the invention, the dehydration of the aggregate sample can be realized by heating. Through stirring the aggregate sample in the dehydration process, the aggregate sample can be heated more uniformly, and the full and quick dehydration of the aggregate sample is realized, so that the dehydration efficiency is improved, and the agglomeration of the aggregate sample in the dehydration process can be effectively prevented through stirring, and the dehydration effect is ensured.
In the embodiment of the present invention, the image pickup section 15 may employ an industrial camera provided with a lens. The frame rate of the selected industrial camera should meet the speed requirement of image acquisition, and the industrial camera can be connected with the user terminal 17 through a data line and transmits the image to the user terminal 17 for image analysis and processing.
The image acquisition component 15 is arranged at the side of the image acquisition area, and dust may be attached to the lens of the image acquisition component 15 in the process of dropping the aggregate sample to the image acquisition area, so that the acquired digital image is unclear, and the accuracy of image analysis is affected. In order to improve the accuracy of image analysis, two industrial cameras may be provided, and specifically, refer to the schematic structural diagram shown in fig. 2. The image analysis results of the two industrial cameras are integrated, so that the accuracy of image analysis is further improved.
In order to ensure that a clearer digital image is acquired, transparent partition plates 19 can be arranged on two sides of an image acquisition area; the aggregate sample falls into the area formed by the two transparent partitions 19; the image pickup element 15 is disposed outside the transparent partition plate 19.
In practical applications, the light source 20 may be disposed outside the transparent partition 19 and at a position directly opposite to the image capturing element 15. The illumination is provided by a light source to ensure that the digital image acquired by the image acquisition component 15 is clearer.
The transparent partition plate 19 can effectively isolate dust from adhering to the lens of the image acquisition component 15, but the transparent partition plate 19 can also adhere to the dust after being used for a long time, and in order to ensure the cleanness of the side wall of the transparent partition plate 19, a cleaning component 21 can be arranged above the transparent partition plate 19 and used for performing dust cleaning treatment on the transparent partition plate.
In a specific implementation, the sweeping component 21 may be composed of an air knife, a transmission pipeline and a solenoid valve arranged on the transmission pipeline.
The air knife is connected with an air source for providing compressed air through a transmission pipeline; the controller 11 is connected with the electromagnetic valve and used for controlling the conduction of the electromagnetic valve so as to form an impact air curtain by using an air knife and perform ash removal treatment on the side wall of the transparent partition plate 19.
In the embodiment of the invention, in order to timely troubleshoot and adjust the problems of the production line equipment and avoid economic loss caused by unqualified aggregate products, the user terminal 17 can also detect whether the characteristic parameters of the aggregate sample meet the preset parameter standard range.
Each type of characteristic parameter has its corresponding parameter criteria range. In the embodiment of the present invention, for the sake of convenience of distinction, a characteristic parameter that does not satisfy the parameter criterion range is referred to as a target characteristic parameter.
The value of the characteristic parameter is often influenced by the equipment parameter of the production line equipment, so that when the target characteristic parameter which does not meet the parameter standard range exists, the equipment parameter of the production line equipment corresponding to the target characteristic parameter can be adjusted.
For example, when the powder content of the aggregate sample exceeds the standard powder content, the manager can adjust the air volume of the dust removal device on the production line through the user terminal 17, so as to improve the dust removal effect.
Besides automatically adjusting the equipment parameters of the production line equipment, the real-time detection result of the aggregate sample can also be fed back to the manager through the user terminal 17, and the manager can select manual control.
For example, when the fineness modulus of the aggregate sample is deviated from the standard fineness modulus, screens with other apertures can be manually selected to replace the screens on the current production line.
When the detection result of the aggregate sample is qualified, the finished product can be transferred to a qualified finished product bin for storage. If the detection result is not qualified, the user terminal 17 may feed back the information of the finished aggregate product, the reason for the unqualified product, and the solution to the administrator. After the equipment on the production line is subjected to parameter adjustment or equipment replacement, the unqualified product can be conveyed to the production line again until the qualified product is obtained.
The characteristic information of the aggregate sample is detected in real time through the user terminal, production line equipment can be adjusted in time, problems of the production line equipment can be eliminated, and economic loss caused by unqualified aggregate products is avoided.
