As shown in Figures 1-8, as an embodiment of image recognition in a mine, the image processing control method of this embodiment includes the following steps;

First of all, image acquisition and processing, within the set distance, the visual sensor regularly takes real-time images of ore on the scraper conveyor, and collects the image together with the boundary of the scraper conveyor; since the boundary of the conveyor is fixed, the ore can be calculated based on it Approximate shape.

Then, crop the image processing, and crop the desired area according to the image pixel data and set the threshold; thereby removing irrelevant areas and reducing the workload of denoising;

Secondly, the area image processing, after targeting the required area, correct the area by transforming, filtering and screening features to process the area, in order to obtain the boundary of the ore in the image of the target area, and perform image denoising processing, image grayscale processing and image binary value Conventional processing methods such as chemical processing to realize numerical processing;

Thirdly, according to the parameters of the matching jaw crusher, set the optimal ore shape of the jaw crusher and store it as the pre-stored image boundary;

In order to reduce the workload of the subsequent jaw crusher, the first scheme is designed. Based on the shape and size of the ore, the comparative image processing is carried out, and the lateral boundary of the scraper conveyor is used as a reference to extract the image boundary feature value of the ore in the image of the target area. And compared with the boundary of the pre-stored image, if the ore boundary in the target area image is smaller than the pre-stored image boundary, it is considered that the ore shape meets the requirements; if the ore boundary in the target area image is greater than the pre-stored image boundary, it is considered that the ore cannot meet the requirements. The claws on the scraper conveyor take the ore out of the scraper conveyor for additional crushing or crush it through the crusher 11; thus realizing the prediction of the size of the ore and avoiding the jaw crusher due to excessive size. Stuck, improving crushing efficiency, not drawn on the claw claw diagram, because it is common knowledge, the present invention focuses on the technology related to the invention point, corresponding to mining equipment, jaw crusher, air duct, support equipment and other conventional Or omit irrelevant technology.

In addition, according to the parameters of the supporting scraper conveyor, the conveying compactness of ore on the scraper conveyor is set and stored as a reference image of compactness distribution, and the reference image of compactness distribution can also be digitized and quantified as The parameter ratio k of the unloaded area of the inner scraper conveyor belt to the total area corresponding to the unit length, the unit length is preferably 1 meter.

As a supporting scheme, in order to increase the distribution compactness of the ore on the scraper conveyor and reduce the generation of empty sections, the second scheme is designed. Based on the distribution compactness of the ore on the scraper conveyor The lateral boundary and vertical boundary of the conveyor are used as reference objects, and the image boundary feature value of the ore in the image of the target area is extracted, and compared with the reference image of the compactness distribution, if the ore compactness of the target area image of the scraper conveyor is less than the lower limit of the compactness distribution reference image , then the scraper conveyor in the rear section will decelerate or stop intermittently, so as to realize energy saving, and use the speed difference to improve the compactness of ore distribution. In addition, the gravity sensor can be used to sense whether the scraper conveyor is overloaded. If it is overloaded, the scraper conveyor at the rear stage will be accelerated, so that the distance between the ores will be opened, and the load of a single scraper conveyor will be reduced. Because the traditional conveyor works continuously and uninterruptedly, it consumes a lot of energy. Because the mining ore is not a continuous output, it will produce long-distance intervals or partial accumulation during the output process. Through the processing of the collected pictures, observe the output process In the distribution of ore density, by adjusting the speed of the corresponding segmented scraper conveyor, the range of no-load and empty travel is reduced. The compactness here refers to the compactness of the distribution on the belt, not the material of the ore itself.

The boundary is obtained through image comparison processing. In order to improve the processing quality, the present invention can be equipped with lighting, increment and other means to improve the recognition effect.

In order to improve efficiency, as a further extension, the next step of the present invention is to realize identification through thermal imaging, because different ores contain different amounts of heat, and the heat inside and at the boundary of the ore is different. Through the identification of heat regions, effective Auxiliary industrial cameras can reduce the power consumption of lighting equipment and facilitate boundary division. Before the comparison image processing, the following steps are performed. First, the thermal imaging image processing, the acquired thermal imaging image is matched with the shape image taken by the industrial camera, and the ore is identified according to the thermal imaging distribution; then, the continuous image processing, According to the thermal imaging image processing and identification, the continuous photographs of ores within the set distance are spliced, and the features are obtained, and the approximate image of the thermal imaging area is extracted; so as to realize the understanding of the ore transportation situation in the section.

Among them, the visual sensor includes industrial cameras, and the thermal imaging camera is the next improvement, which is ready to be applied to coal mining; the ore is vibratingly conveyed on the scraper conveyor, so that the position of the ore is constantly changing during the transportation, so as to take images of the ore from different angles Data collection, through the impact of collision and vibration between the ores, realizes the continuous change of the position of the ores. As long as there is an unqualified direction, it is considered that its shape is too large and needs to be pre-crushed.

As shown in Figure 8, as the hardware structure of the supporting method, the specific application is realized by means of the scraper conveyor and the supporting Internet of Things;

For the Internet of Things, at the perception layer, it includes industrial cameras and/or thermal imaging cameras set at a fixed distance along the direction of ore transmission, for image acquisition and image processing of the transported ore; gravity sensors, for perception of the scraper The ore weight changes on the conveyor; at the network layer, there are Internet, local area network and/or Bluetooth for image data and/or weight information transmission; at the application layer, there is a background station; The host computer performs data transmission and image processing.

As a mine work process, in conjunction with Fig. 1-Fig. 8, the image processing control process of this embodiment is based on the ore transmission device based on the image processing control method; the following process is performed;

S2, the collected data meets the set threshold, and it is judged whether to carry out downhole operation;

S3, if underground operations are possible, manual and/or equipment access, excavation or mining;

S4, the ore explored and mined is sent to the scraper conveyor 10;

S5, through the visual sensor and/or the gravity sensor to perceive the weight change of the corresponding scraper conveyor 10 and/or the uplink section of the differential scraper 9, when the gravity is greater than the set threshold, the differential scraper 9 intermittently moves forward set a distance

S6, the visual sensor detects the particle size of the ore, and when the particle size is greater than the set threshold, the crusher 11 is started to press down to crush the ore;

S7, collecting the conveyor belt 12 for guiding;

S8, the jaw crusher 13 crushes the ore;

S9, classifying and screening the roller crushed particles.

Among them, in S5, the different positions of the top crankshaft 17 on the gap between the top and the top of the gap cause the ore to squirm; Set the threshold; then, the motor drives the eccentric rotating shaft 20 to rotate, so that the swing crank 21 accelerates longitudinally to elongate or shorten, and the lifting wedge 26 passes through the side lever 16 through the one-way swing baffle 27 to reach the stroke end; secondly, The one-way swing baffle plate 27 and the lower part of the lifting wedge block 26 are inserted into the gap between the adjacent side driving levers 16; row set distance;

In S6, at first, the lower pressing frame 31 is pressed down to the sides of the swinging crushing bottom plate 29, so that the swinging crushing bottom plate 29 becomes a horizontal state; The shaped ore is hammered and pressed down; secondly, the ore crushing situation is observed by taking pictures and images with the supporting industrial camera. If the ore meets the set requirements, the lower pressing frame 31 rises, so that the swing crushing bottom plate 29 swings downward under gravity. To output ore, vibration is generated by the buffer spring 30 to oscillate and output the ore attached to the swing crushing bottom plate 29, and the upper swing stroke is limited by the process inclined plane 32;

In S9, at first, the rolled ore of the two-way opposing pressure roller group 35 that passes through two directions of grinding falls into the large-end inlet 37, and then is output through the small-end outlet 38; If it is blocked, the ore in the swing frame body 36 will continue to accumulate, making the center of gravity close to the big-end inlet 37, and making the big-end inlet 37 face downward. The push seat 42 goes down under the action of gravity, and the push plate 43 cleans the ore; secondly, the traction seat 40 pulls the sliding push seat 42 to the small end outlet 38 through the traction cable 41, so that the center of gravity after no-load moves to the small end outlet 38 , Then, the traction cable 41 is unclamped, so that the small end outlet 38 sinks, and at the same time, the sliding push seat 42 sinks.
