[0002] In recent years, with the rapid development of my country's coal mining industry, the utilization rate of coal mines has become increasingly higher. Coal mines are widely used in the iron-making and power generation industries, but due to the relatively long transportation process, there is a lack of effective control measures. At present, magnetic separators are mainly used to separate high-hardness iron foreign matter, but there is a lack of effective control measures for other high-hardness foreign matter such as ceramics or alloys. Due to the high hardness of foreign matter, it is easy to cause wear of other equipment after entering the equipment through the coal conveyor belt. There are currently no better control measures at home and abroad, mainly relying on magnetic separators and screen plates, but due to the high hardness of foreign matter, it will still cause relatively large damage to the screen plate, resulting in large economic losses.

[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0048] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of the coal conveyor belt foreign matter monitoring equipment in the hardware operating environment involved in the embodiment of the present invention.

The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The structure shown in does not constitute a limitation on the coal conveyor belt foreign matter monitoring device, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0051] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a coal conveyor belt foreign matter monitoring program.

[0052] exist Figure 1 In the coal conveyor belt foreign object monitoring device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the coal conveyor belt foreign object monitoring device of the present invention can be set in the coal conveyor belt foreign object monitoring device, and the coal conveyor belt foreign object monitoring device calls the coal conveyor belt foreign object monitoring program stored in the memory 1005 through the processor 1001, and executes the coal conveyor belt foreign object monitoring method provided by the embodiment of the present invention.

[0053] The embodiment of the present invention provides a method for monitoring foreign matter on a coal conveyor belt. Figure 2 , Figure 2 It is a schematic flow chart of the first embodiment of the method for monitoring foreign matter on a coal conveyor belt of the present invention.

[0054] In this embodiment, the coal conveyor belt foreign matter monitoring method comprises the following steps:

[0055] Step S10: obtaining the current coal weight corresponding to the coal conveyor belt, and when the current coal weight does not meet the preset weight condition, controlling the coal conveyor belt to stop running;

[0056] It should be noted that the executor of this embodiment can be the above-mentioned coal conveyor belt foreign matter monitoring equipment with image processing, network communication and program running functions, or it can be other equipment that can achieve the same or similar functions. This embodiment does not impose specific restrictions on this.

[0057] It can be understood that in this embodiment, the current weight of coal blocks corresponding to the coal conveyor belt can be collected by the pressure sensor. The current weight of coal blocks refers to the weight of all coal blocks transported on the coal conveyor belt. The preset weight condition is a pre-set weight condition, which can be set according to actual conditions, such as less than 20 kilograms, less than 30 kilograms, and can also be set to other conditions. This embodiment does not impose specific restrictions on this.

[0058] Step S20: After the coal conveyor belt stops running, collecting a current coal conveyor image corresponding to the coal conveyor belt;

[0059] Furthermore, in this embodiment, the step S20 includes: after the coal conveyor belt stops running, collecting an initial coal conveying image corresponding to the coal conveyor belt; preprocessing the initial coal conveying image to obtain a processed initial coal conveying image; and extracting key areas of the processed initial coal conveying image to obtain a current coal conveying image.

[0060] It should be understood that in image analysis, the quality of the image directly affects the design of the recognition algorithm and the accuracy of the effect. Therefore, preprocessing is required before image analysis (feature extraction, segmentation, matching and recognition, etc.). The main purpose of image preprocessing is to eliminate irrelevant information in the image, restore useful real information, enhance the detectability of relevant information, and simplify the data to the maximum extent, thereby improving the reliability of feature extraction, image segmentation, matching and recognition. In this embodiment, image preprocessing may include denoising the current coal conveying image, reducing the noise of the current coal conveying image, and may also include other operations for preprocessing the current coal conveying image, and this embodiment does not impose specific restrictions on this.

[0061] In the specific implementation, common image noise includes Gaussian noise, Rayleigh noise, gamma noise, exponential noise and uniform noise. Specifically, the image can be denoised by the NL-Means (Non-Local Means) algorithm. This algorithm uses the redundant information commonly found in natural images to denoise. It uses the entire image for denoising, searches for similar areas in the image in units of image blocks, and then averages these areas, which can effectively remove the Gaussian noise in the image. The image can also be denoised by the BM3D (Block-matching and 3D filtering) algorithm. The BM3D algorithm has two major steps, namely basic estimation and final estimation. In these two major steps, there are three small steps: similar block grouping, collaborative filtering and aggregation, which can significantly remove the noise of the image.

[0062] It can be understood that key area extraction refers to the extraction of areas corresponding to the coal conveyor belt and the coal blocks transported on the coal conveyor belt. The specific method of key area extraction can be to detect the edges of the extraction area, which can be specifically detected by the canny edge detection algorithm, or to obtain the pixel information corresponding to all pixel points in the processed initial coal conveying image. The pixel information refers to the pixel coordinate values ​​of all pixel points, that is, the position of the pixel points in the processed initial coal conveying image. The specific method of key area extraction can be to pre-set the pixel range of the key area according to actual conditions, and then extract all pixel points in the processed initial coal conveying image that are within the pixel range. The current coal conveying image can be obtained based on all the extracted pixel points.

[0063] Step S30: performing image segmentation on the current coal conveying image to obtain each divided coal conveying image, and performing foreign matter monitoring based on each divided coal conveying image.

[0064] It can be understood that image segmentation refers to segmenting the current coal conveying image along the direction of the coal conveying belt, and multiple coal conveying images can be obtained after segmentation.

[0065] In a specific implementation, foreign matter monitoring can be performed based on each coal conveying image after division. Foreign matter may include high-hardness foreign matter or other items that do not belong to coal blocks. After the current coal conveying image is divided, foreign matter monitoring can be performed on each coal conveying image separately, thereby obtaining more accurate monitoring results.

[0066] This embodiment obtains the current coal weight corresponding to the coal conveyor belt, and controls the coal conveyor belt to stop running when the current coal weight does not meet the preset weight condition. After the coal conveyor belt stops running, the current coal conveying image corresponding to the coal conveyor belt is collected, and then the current coal conveying image is divided to obtain each divided coal conveying image, and foreign matter monitoring is performed according to each divided coal conveying image. This embodiment controls the coal conveyor belt to stop running when the current coal weight does not meet the preset weight condition, and can timely detect whether foreign matter may appear on the coal conveyor belt according to the current coal weight, and then divides the current coal conveying image, and monitors foreign matter according to each divided coal conveying image, and can divide the collected current coal conveying image into multiple images, and then monitor foreign matter on the multiple images, so that foreign matter on the coal conveyor belt can be accurately monitored.

[0067] refer to Figure 3 , Figure 3 It is a schematic flow chart of the second embodiment of the method for monitoring foreign matter on a coal conveyor belt of the present invention.

[0068] Based on the above first embodiment, in this embodiment, step S10 includes:

[0069] Step S101: acquiring a real-time coal conveying image corresponding to the coal conveying belt, and performing preliminary foreign matter monitoring according to the real-time coal conveying image;

[0070] It can be understood that preliminary foreign matter monitoring refers to preliminary foreign matter monitoring of the coal blocks on the coal conveyor belt, that is, preliminary monitoring of whether there are foreign matters in the coal blocks on the coal conveyor belt.

[0071] In a specific implementation, the real-time coal conveying image corresponding to the coal conveyor belt can be collected by a camera in real time. The camera needs to collect the complete coal conveyor belt and the coal blocks on the coal conveyor belt.

[0072] Furthermore, in order to accurately determine whether the preliminary foreign matter monitoring is successful, in the present embodiment, the step S101 includes: obtaining a real-time coal conveying image corresponding to the coal conveyor belt, performing image processing on the real-time coal conveying image, and obtaining a processed real-time coal conveying image; obtaining the color information of the coal blocks in the processed real-time coal conveying image; and determining that the preliminary foreign matter monitoring is successful when the coal block color information meets the preset color information.

[0073] It should be understood that the image processing in this embodiment includes preprocessing and key area extraction, and the preprocessing process and the key area extraction process are consistent with those of the first embodiment described above, which will not be elaborated in this embodiment.

[0074] It is understandable that the coal block color information refers to the color information corresponding to the coal blocks transported on the coal conveyor belt. The preset color information is the color of the coal block itself, which can be set according to actual conditions. It is generally black, and can also be dark gray. This embodiment does not impose specific restrictions on this.

[0075] In a specific implementation, when the color information of the coal block in the real-time coal conveying image meets the preset color information, that is, when it is consistent with the actual color of the coal block, it indicates that there may be no foreign matter in the coal block, that is, the preliminary foreign matter monitoring is successful.

[0076] Furthermore, in order to determine the situation when the preliminary foreign matter monitoring fails, in the present embodiment, when the color information of the coal block does not meet the preset color information, it is determined that the preliminary foreign matter monitoring has failed; after the preliminary foreign matter monitoring fails, the coal conveyor belt position information corresponding to the preset color information is obtained; and an early warning is issued based on the coal conveyor belt position information.

[0077] It is understandable that when the color information of the coal block does not meet the preset color information, it means that the initial foreign matter monitoring has failed, that is, objects that are not black may appear. At this time, it is necessary to control the coal conveyor belt to stop running, and obtain the coal conveyor belt position information corresponding to the preset color information, and report the coal conveyor belt position information to the management personnel so that the management personnel can deal with the abnormal situation in time.

[0078] This embodiment can quickly obtain preliminary foreign matter monitoring results by performing preliminary foreign matter monitoring on the coal blocks on the coal conveyor belt, and determine whether subsequent foreign matter monitoring is required based on the preliminary foreign matter monitoring results, thereby reducing the difficulty of foreign matter monitoring and improving efficiency.

[0079] Step S102: when the preliminary foreign matter monitoring is successful, obtaining the weights of multiple coal blocks collected by multiple pressure sensors arranged under the coal conveyor belt;

[0080] Step S103: determining weight information corresponding to each pressure sensor according to the position information of the multiple pressure sensors;

[0081] It should be noted that the position information of the pressure sensor may be position information relative to the coal conveyor belt, for example, the left end, middle end, right end, etc. of the coal conveyor belt, and this embodiment does not impose any specific limitation on this.

[0082] It is understandable that, due to the different locations of the pressure sensors, the weight of the coal blocks collected by each pressure sensor may be different.

[0083] In a specific implementation, the corresponding weight information can be determined based on the position information of the pressure sensor. Specifically, it can be set that the closer the pressure sensor is to the midpoint of the coal conveyor belt, the greater the weight corresponding to the pressure sensor; the farther the pressure sensor is from the midpoint of the coal conveyor belt, the smaller the weight corresponding to the pressure sensor. The specific weight information can be set according to actual conditions, and this embodiment does not impose any specific restrictions on this.

[0084] Step S104: determining the current weight of the coal block according to the weight information and the weights of the multiple coal blocks, and controlling the coal conveyor belt to stop running when the current weight of the coal block does not meet the preset weight condition.

[0085] It is understandable that each coal block weight corresponds to a weight information, and the current coal block weight can be obtained by weighted summing the weight information and the weights of multiple coal blocks.

[0086] This embodiment obtains the real-time coal conveying image corresponding to the coal conveying belt, performs preliminary foreign matter monitoring based on the real-time coal conveying image, and when the preliminary foreign matter monitoring is successful, obtains the weights of multiple coal blocks collected by multiple pressure sensors set under the coal conveying belt, and then determines the weight information corresponding to each pressure sensor based on the position information of the multiple pressure sensors, and then determines the current weight of the coal block based on the weight information and the weights of the multiple coal blocks. When the current weight of the coal block does not meet the preset weight condition, the coal conveying belt is controlled to stop running. This embodiment determines the weight information corresponding to each pressure sensor based on the position information of multiple pressure sensors, and then determines the current weight of the coal block based on the weight information and the weights of multiple coal blocks. Compared with the existing method of collecting the current weight of the coal block through one pressure sensor, this embodiment collects the weight of the current coal block through multiple pressure sensors, which can collect the current weight of the coal block more accurately.

[0087] refer to Figure 4 , Figure 4 It is a schematic flow chart of the third embodiment of the method for monitoring foreign matter on a coal conveyor belt of the present invention.

[0088] Based on the above embodiments, in this embodiment, step S30 includes:

[0089] Step S301: Acquire the length information of the coal conveyor belt, and determine the number of image divisions according to the length information;

[0090] It should be noted that the length information refers to the length of the entire coal conveyor belt. The longer the length of the coal conveyor belt, the more times the image is divided. The specific number can be set according to the actual situation. For example, when the length of the coal conveyor belt is 100 meters, the number of image divisions can be set to 100 times. The specific value can also be set to other values. This embodiment does not impose any specific restrictions on this.

[0091] Step S302: dividing the current coal transport image according to the number of image divisions to obtain each coal transport image after division;

[0092] In the specific implementation, the current coal conveying image is divided according to the number of image divisions, and the sizes of the divided coal conveying images can be the same or different. It can be specifically determined based on whether there is an area on the coal conveyor belt where coal blocks are not transported. When coal blocks are not transported in a certain area of ​​the coal conveyor belt, the image corresponding to the area can be deleted, thereby reducing the subsequent foreign matter monitoring time and improving the foreign matter monitoring efficiency.

[0093] Step S303: amplifying each of the divided coal conveying images to obtain each amplified coal conveying image;

[0094] It is understandable that image magnification can be achieved through a nearest point interpolation algorithm, a bilinear interpolation algorithm, a bicubic interpolation algorithm, or an adaptive spline interpolation and enhancement technique.

[0095] Step S304: performing foreign matter monitoring based on the amplified coal conveying images.

[0096] Further, in this embodiment, the step S304 includes: obtaining the coal conveyor belt status information in each of the enlarged coal conveyor images; and when there is abnormal status information in the coal conveyor belt status information, determining that there is foreign matter on the coal conveyor belt.

[0097] It should be noted that the coal conveyor belt status information refers to the current status of the coal conveyor belt, and may include angle information of the coal conveyor belt depression, offset information of the coal conveyor belt, etc. This embodiment does not impose specific restrictions on this.

[0098] It is understandable that the abnormal status information refers to the status information corresponding to the abnormality of the coal conveyor belt, which may include that the angle of the coal conveyor belt is too large, the offset of the coal conveyor belt is too large, etc. This embodiment does not make specific restrictions on this.

[0099] In a specific implementation, when there is abnormal status information in the coal conveyor belt status information, it is determined that there is a foreign object on the coal conveyor belt. At this time, the specific location information of the foreign object can be obtained, and an early warning can be issued to the management personnel, reminding the management personnel to investigate the abnormal condition.

[0100] This embodiment obtains the length information of the coal conveyor belt, determines the number of image divisions according to the length information, and then divides the current coal conveyor image according to the number of image divisions to obtain each divided coal conveyor image, and then amplifies each divided coal conveyor image to obtain each amplified coal conveyor image, and then monitors foreign matter based on each amplified coal conveyor image. This embodiment can obtain a clear and accurate coal conveyor image by dividing the current coal conveyor image and amplifying each divided coal conveyor image, so as to accurately monitor foreign matter on the coal conveyor belt.

[0101] In addition, an embodiment of the present invention further proposes a storage medium, on which a coal conveyor belt foreign matter monitoring program is stored. When the coal conveyor belt foreign matter monitoring program is executed by a processor, the coal conveyor belt foreign matter monitoring method described above is implemented.

[0102] Reference Figure 5 , Figure 5 This is a structural block diagram of the first embodiment of the coal conveyor belt foreign matter monitoring device of the present invention.

[0106] The foreign matter monitoring module 30 is used to divide the current coal conveying image, obtain each divided coal conveying image, and perform foreign matter monitoring according to each coal conveying image.

[0107] This embodiment obtains the current coal weight corresponding to the coal conveyor belt, and controls the coal conveyor belt to stop running when the current coal weight does not meet the preset weight condition. After the coal conveyor belt stops running, the current coal conveying image corresponding to the coal conveyor belt is collected, and then the current coal conveying image is divided to obtain each divided coal conveying image, and foreign matter monitoring is performed according to each divided coal conveying image.
