Description

Technical Field

[0001] This invention relates to the field of mining operation technology, specifically to a mining spraying equipment and its control method based on artificial intelligence manufacturing technology. Background Technology

[0002] Intelligent manufacturing is a human-machine integrated intelligent system composed of intelligent machines and human experts. It can perform intelligent activities during the manufacturing process, such as analysis, reasoning, judgment, conceptualization, and decision-making. Through collaboration between humans and intelligent machines, it expands, extends, and partially replaces the mental labor of human experts in the manufacturing process. It updates the concept of manufacturing automation, extending it to flexibility, intelligence, and high integration.

[0003] In the mining operation, the main task is the extraction of mineral resources. During this process, in order to deal with the dust generated during the extraction of mineral resources, it is necessary to spray water on the surface of the mine regularly or continuously to reduce dust pollution caused by mining operations. At the same time, the sprayed water can cool down the mine and increase the humidity of the mine to ensure the safety of mining operations.

[0004] However, in the process of spraying water in mine roadways, the traditional spraying method involves manually introducing water and continuously spraying it into the roadway. This spraying method may have certain drawbacks in actual mine roadway operations:

[0005] 1. Continuous spraying of mine roadways can easily lead to excessive humidity or water accumulation inside the roadways.

[0006] 2. If personnel are assigned to monitor the spray locations, it will increase the manpower required for mining operations;

[0007] 3. During spraying, it is difficult to control the spraying intensity at different locations based on the actual mining location;

[0008] 4. During the mining process, workers will pass by the spraying location, and the spraying work may affect the workers' movement.

[0009] 5. During mining operations, the high cab of a truck makes it difficult to effectively check for pedestrians in blind spots, which can easily lead to accidents.

[0010] 6. During spraying, the spray route is usually selected based on experience, which makes it impossible to achieve the optimal design of the spray route.

[0011] Therefore, we have made improvements to this by proposing a mine spraying equipment and its control method based on artificial intelligence manufacturing technology. Summary of the Invention

[0024] A control method for mine spraying equipment based on artificial intelligence manufacturing technology includes the following specific steps:

Multiple target points exist. The dust suppression truck selects the target point with the shortest route as its path. The truck travels and sprays water according to the shortest path planned by the Dijkstra algorithm. The water flow rate is adjusted based on temperature and humidity sensor values; if the temperature or humidity exceeds a set threshold, the water flow rate increases; if the temperature or humidity exceeds the area's average temperature, the water flow rate increases; if the temperature or humidity is below the set threshold, the water flow rate decreases.

When the increased detection frames overlap, a collision risk is identified, and the Alibaba Cloud server sends an alarm message to the vehicle terminal while simultaneously controlling the vehicle's buzzer to sound.

[0034] The beneficial effects of this invention are:

[0035] 1. This type of mine spraying equipment and its control method based on artificial intelligence manufacturing technology uses a control network to mark solenoid valves at different positions and controls the corresponding spray pipe groups at the required spraying locations to carry out spraying work. Furthermore, by controlling the opening frequency of the solenoid valves through the control network, the impact of the spraying work on the roadway humidity can be effectively controlled, effectively avoiding excessive humidity or water accumulation in the roadway.

[0060] Example: Figures 1-9As shown, the present invention discloses a mine spraying device based on artificial intelligence manufacturing technology, comprising a main water pipe 1 and a detection frame 10. Several first metal connecting pieces 2 are fixedly sleeved on the side of the main water pipe 1. One end of the first metal connecting piece 2 is bolted to a fixing frame 103.

An infrared scanning component 8 is provided between two spray pipe assemblies 5. A third metal connecting piece 9 is provided on the infrared scanning component 8.

[0061] The main water pipe 1 is used to establish a water passage for the entire mining roadway and to supply water for the corresponding spray pipe group 5. The first metal connecting piece 2 is used to fix the main water pipe 1, and the interface 3 is used to connect with the hose 4, so that the spray water can be guided to the spray pipe group 5 through the hose 4. The second metal connecting piece 6 is used to fix the spray pipe group 5 and fix the spray pipe group 5 at the spray position inside the mining roadway. The spray direction control component 7 can control the spray pipe group 5 to always spray the side where no one passes by, so as to avoid affecting the mining workers. The infrared scanning component 8 is used to scan the position of the workers. The third metal connecting piece 9 is used to fix the infrared scanning component 8.

[0062] The spray pipe assembly 5 includes a first L-shaped pipe section 501, a second L-shaped pipe section 502, and a middle pipe section 503. One end of the middle pipe section 503 is fixed to the first L-shaped pipe section 501, and the other end of the middle pipe section 503 is fixed to the second L-shaped pipe section 502.

[0063] The first L-shaped pipe section 501 and the second L-shaped pipe section 502 can respectively control the spraying water to spray to different positions in the mine roadway, and the middle pipe section 503 guides the first L-shaped pipe section 501 and the second L-shaped pipe section 502.

[0064] The spray direction control assembly 7 includes a tilting cylinder section 701, an annular extension clamp section 702, a driven gear 703, a driving gear 704, a protective shell 705, and a first stepper motor 706. The tilting cylinder section 701 is movable inside the spray pipe assembly 5. The annular extension clamp section 702 is fixed to the outside of the tilting cylinder section 701. The driving gear 704 is located above the driven gear 703 and meshes with the driven gear 703. The first stepper motor 706 is fixed inside the protective shell 705, and the output shaft of the first stepper motor 706 is connected to the driving gear 704 via a coupling.

[0065] When the first stepper motor 706 is working, it can control the rotation of the drive gear 704. By utilizing the meshing between the drive gear 704 and the driven gear 703, the driven gear 703 can be driven to rotate, which in turn drives the rotation of the annular extension clamp 702 and the tilting cylinder 701.

[0066] The infrared scanning assembly 8 includes a rotating rod 801 and an infrared scanner carrier plate 802. The infrared scanner carrier plate 802 is fixed to the bottom end of the rotating rod 801, and the third metal connecting piece 9 is movably connected to the side of the rotating rod 801.

[0067] The infrared scanner carrier plate 802 is fixed by the rotating rod 801. The infrared scanner on the infrared scanner carrier plate 802 can scan when the operator passes by and determine the position of the operator.

[0068] Among them, the first metal connecting piece 2, the second metal connecting piece 6 and the third metal connecting piece 9 are each provided with several through holes 201;

[0069] The corresponding number of bolts can be passed through the through hole 201 and fixed to the rock inside the mine roadway, thereby realizing the fixed installation of the main water pipe 1, the spray pipe group 5 and the infrared scanning component 8.

[0070] Among them, a solenoid valve 301 is fixedly sleeved on the side of the interface 3, and several solenoid valves 301 located on the interface 3 are independently controlled.

[0071] The solenoid valve 301 located on the interface 3 can be independently controlled to control the water flow through the interface 3 connected to the spray pipe group 5.

[0072] The first L-shaped pipe section 501 and the second L-shaped pipe section 502 have the same structure and are symmetrically distributed at both ends of the middle pipe section 503. Both the first L-shaped pipe section 501 and the second L-shaped pipe section 502 are provided with a number of spray holes 5011.

[0073] Water enters the first L-shaped pipe section 501 and the second L-shaped pipe section 502, and then sprays out from the spray hole 5011, which can realize the spraying work of the mine roadway.

[0074] Among them, the angle between the spray hole 5011 and the vertical direction is -60° to 60°, and five spray holes 5011 form a spray group. The angle between two spray holes 5011 located in the same spray group and in adjacent positions is 30°.

[0075] By controlling the spray nozzles 5011 to be oriented in an arc-shaped, dispersed manner, the spray range of the spray pipe assembly 5 can be increased, and the uniformity of spraying during a single spray can also be improved.

[0076] Among them, the inner diameter of the middle pipe section 503 is smaller than the inner diameter of the first L-shaped pipe section 501;

[0077] The middle pipe section 503 is used to handle the water convection between the first L-shaped pipe section 501 and the second L-shaped pipe section 502, increasing the inner diameter of the pipes of the first L-shaped pipe section 501 and the second L-shaped pipe section 502, and thus, in conjunction with the spray hole 5011, can effectively increase the spray area of ​​the spray pipe group 5.

[0078] The annular extension retaining section 702 includes an inner retaining ring 7021, an annular piece 7022, and an outer retaining ring 7023, which are fixed in sequence. The thickness of the inner retaining ring 7021 and the outer retaining ring 7023 is greater than the thickness of the annular piece 7022. The inner retaining ring 7021 is fixed to the middle of the flipping cylinder section 701, and the outer retaining ring 7023 is fixed to the inner side of the driven gear 703. The outer side of the middle tube section 503 is provided with a sleeve 504. The middle of the sleeve 504 is provided with an annular channel 5041 for use with the annular piece 7022. Both ends of the sleeve 504 are fixed to the protective shell 705.

[0079] The ring plate 7022 can rotate freely within the annular channel 5041, thereby enabling synchronous rotation between the inner retaining ring 7021 and the outer retaining ring 7023. By controlling the thickness of the ring plate 7022, water can be prevented from flowing out from the gap between the ring plate 7022 and the inner retaining ring 7021 or the outer retaining ring 7023. At the same time, the sleeve section 504 is used to align the central pipe section 503 to further prevent water from overflowing.

[0080] Among them, a protective box 901 is fixedly connected to the third metal connecting piece 9 near one end of the rotating rod 801. A second stepper motor 902 is fixedly installed inside the protective box 901. The output shaft of the second stepper motor 902 passes through the protective box 901 and is connected to the rotating rod 801 through a coupling.

[0081] When the second stepper motor 902 is working, it can drive the rotating rod 801 to rotate, which can control the tilt angle of the infrared scanner carrier plate 802.

[0082] Specifically, according to the greedy algorithm in step S8: Under the condition that the water-spraying dust suppression truck is traveling at a constant speed, after each monitoring point in the mining area reports the dust particulate matter detection results (PM2.5 / PM10), the location where the dust particulate matter monitoring exceeds the standard is designated as the target point. The shortest path from the starting point of the water-spraying dust suppression truck to the target point is found based on the Dijkstra algorithm. After the water-spraying dust suppression truck completes one round of water spraying from its starting point to the target point, monitoring points where the dust particulate matter detection results (PM2.5 / PM10) no longer exceed the standard are no longer considered target points. The shortest path from the location of the water-spraying dust suppression truck to the next target point is recalculated based on the Dijkstra algorithm until the number of target points exceeding the dust particulate matter monitoring standard is 0. When multiple target points exist, the water-spraying dust suppression... The vehicle selects the target point with the shortest route as its route; the water-spraying dust suppression truck travels and sprays water according to the shortest route planned by the Dijkstra algorithm. The water flow rate is adjusted based on the temperature and humidity sensor values. If the temperature and humidity are higher than a set threshold, the water flow rate is increased; if the temperature and humidity are higher than the regional average temperature, the water flow rate is increased; if the temperature and humidity are lower than the set threshold, the water flow rate is decreased. Multiple cameras in the mine are accessed and uploaded to the Alibaba Cloud server. The image stitching APAP algorithm is used to stitch together an overall top-down view of the mine's roads. The deep learning YOLOv5 algorithm is used to detect the water-spraying dust suppression truck and pedestrians, and the detection frame size is increased to 1.2 times. When the increased detection frames overlap, a collision risk is determined. At this time, the Alibaba Cloud server sends an alarm message to the vehicle terminal and controls the vehicle's buzzer to sound.

[0083] Working principle

[0084] First, slowly drive the truck 101 forward, build the main water pipe 1 and fix it with the first metal connecting piece 2. Then, mark the corresponding interface 3 according to the position of the solenoid valve 301, pass the corresponding number of bolts through the through hole 201, and fix it to the rock inside the mine tunnel with the bolts, thereby realizing the fixed installation between the main water pipe 1 and the mine rock wall.

[0085] Then, fix the spray pipe assembly 5 at the required spraying position, and fix the infrared scanning component 8 near the spray pipe assembly 5. Specifically, use bolts to pass through the through hole 201 on the second metal connecting piece 6 and fix it to the rock wall to fix the position of the spray pipe assembly 5. Use bolts to pass through the through hole 201 on the third metal connecting piece 9 and fix it to the rock wall to fix the position of the infrared scanning component 8.

[0086] Then, one end of the hose 4 is fixed to the interface 3 via a flange, and the other end of the hose 4 is fixed to the spray pipe assembly 5 via a flange, so that the spray pipe assembly 5 can be connected to the interface 3 in the vicinity.

[0087] Then, a control network for the sprinkler water supply is established, and the solenoid valve 301 on the interface 3 connected to the sprinkler pipe group 5 is opened according to the network control. At this time, the water flow is introduced from the main water pipe 1 into the corresponding sprinkler pipe group 5.

[0088] During the spraying process, the switching frequency of the solenoid valve 301 is controlled to ensure sufficient humidity in the mine roadway and prevent water accumulation inside the roadway.

[0089] At this time, the infrared scanning component 8 scans and monitors the passing position of the operator, and then controls the spray direction control component 7 to work through the control network to realize spraying on the passage where no operator passes. Specifically, the rotating rod 801 fixes the infrared scanner carrier plate 802. The infrared scanner on the infrared scanner carrier plate 802 can scan when the operator passes by and determine the position of the operator. Then, according to the monitored position of the operator, the first stepper motor 706 is started, controlling the drive gear 704 to rotate, using the drive gear The meshing between wheel 704 and driven gear 703 can drive driven gear 703 to rotate, which in turn drives the annular extension clamp 702 and the tilting cylinder 701 to rotate. The tilting cylinder 701 rotates 180° each time. During this process, one end of the tilting cylinder 701 is pressed against and sealed to the spray hole 5011, while the other end ensures that water can pass through the spray hole 5011 normally. The spray hole 5011 is arc-shaped and dispersed, which can increase the single spray range of the spray pipe group 5 and improve the uniformity of single spray.

[0090] When the infrared scanning component 8 is working, the scanning angle of the infrared scanning component 8 is controlled by the control network. Specifically, the second stepper motor 902 is controlled to work, driving the rotating rod 801 to rotate. At this time, the tilt angle of the infrared scanner carrier plate 802 can be controlled.

[0091] Finally, based on the mine's operational conditions, spraying operations are carried out in the mine roadways during designated time periods to replenish humidity and reduce dust in the mine roadways.

[0092] Simultaneously, according to the greedy algorithm in step S8: Under the condition that the water-sprinkling dust suppression truck travels at a constant speed, after each monitoring point in the mining area reports its particulate matter detection results (PM2.5 / PM10), the location where particulate matter exceeds the standard is designated as the target point. The shortest path from the starting point of the water-sprinkling dust suppression truck to the target point is found based on the Dijkstra algorithm. After the water-sprinkling dust suppression truck completes one round of water spraying from its starting point to the target point, monitoring points where the particulate matter detection results (PM2.5 / PM10) no longer exceed the standard are no longer considered target points. The shortest path from the starting point of the water-sprinkling dust suppression truck to the next target point is recalculated based on the Dijkstra algorithm until the number of target points exceeding the particulate matter standard is 0. When multiple target points exist, the water-sprinkling dust suppression truck... The route is selected based on the shortest path travel time to the target point. The water-spraying truck travels and sprays water according to the shortest path planned by the Dijkstra algorithm. The water flow rate is adjusted based on temperature and humidity sensor readings; if the temperature and humidity exceed a set threshold, the water flow rate increases; if the temperature and humidity exceed the area's average temperature, the water flow rate increases; if the temperature and humidity are below the set threshold, the water flow rate decreases. Multiple cameras in the mine are accessed and uploaded to the Alibaba Cloud server. The APAP image stitching algorithm is used to stitch together a top-down view of the entire mine road system. The YOLOv5 deep learning algorithm is used to detect the water-spraying truck and pedestrians, and the detection frame size is increased by 1.2 times. When the increased detection frames overlap, a collision risk is identified. At this point, the Alibaba Cloud server sends an alarm to the vehicle terminal and simultaneously activates the vehicle's buzzer.

[0093] This allows for the completion of spraying work in the mine, and by utilizing multiple methods in the spraying process, the practical effectiveness of spraying work in mine operations is improved.

3. A control method for a mine spraying equipment based on artificial intelligence manufacturing technology according to any one of claims 1-2, characterized in that, The specific steps include the following: Step S1: Construct and fix the main water pipe, and then mark the corresponding interface according to the position of the solenoid valve; Step S2: Fix the spray pipe assembly at the required spraying location, and fix the infrared scanning component near the spray pipe assembly; Step S3: Connect the spray pipe assembly to the nearby interface; Step S4: Establish a control network for the sprinkler water supply, and open the solenoid valve on the interface connected to the sprinkler pipe group according to the network control. At this time, the water flow is introduced from the main water pipe into the corresponding sprinkler pipe group. Step S5: During the spraying process, control the switching frequency of the solenoid valve to prevent water accumulation inside the mine roadway while ensuring sufficient humidity. Step S6: During the spraying process, the infrared scanning component scans and monitors the passing position of the workers, and then controls the spraying direction control component to work through the control network to spray the passage where no workers are passing; Step S7: When the infrared scanning component is working, the scanning angle of the infrared scanning component is controlled by the control network, and a corresponding temperature and humidity sensor can be installed at the infrared scanning component. Step S8: Spraying is carried out in the mine roadway during the control period to achieve the work of replenishing humidity, reducing dust and cooling in the mine roadway. At the same time, the optimal spraying path is selected based on the greedy algorithm and Dijkstra's algorithm.

4. The control method for a mine spraying equipment based on artificial intelligence manufacturing technology according to claim 3, characterized in that, According to the greedy algorithm in step S8: Under the condition that the water-sprinkling dust suppression truck is traveling at a constant speed, after each monitoring point in the mining area reports the dust particulate matter detection results (PM2.5 / PM10), the location where the dust particulate matter monitoring exceeds the standard is designated as the target point. The shortest path from the starting point of the water-sprinkling dust suppression truck to the target point is found based on the Dijkstra algorithm. After the water-sprinkling dust suppression truck completes one round of water spraying from its starting point to the target point, monitoring points where the dust particulate matter detection results (PM2.5 / PM10) no longer exceed the standard are no longer considered target points. The shortest path from the starting point of the water-sprinkling dust suppression truck to the next target point is recalculated based on the Dijkstra algorithm until the number of target points exceeding the dust particulate matter monitoring standard is 0. When there are multiple target points, the water-sprinkling dust suppression truck selects... The shortest path time is used as the route; the water sprinkler truck travels and sprinkles water according to the shortest path planned by the Dijkstra algorithm. The water flow rate is adjusted according to the temperature and humidity sensor values. If the temperature and humidity are higher than the set threshold, the water flow rate is increased. If the temperature and humidity are higher than the regional average temperature, the water flow rate is increased. If the temperature and humidity are lower than the set threshold, the water flow rate is decreased. Multiple cameras in the mine are called and uploaded to the Alibaba Cloud server. The image stitching APAP algorithm is used to stitch together the overall road top view of the mine. The deep learning YoloV5 algorithm is used to detect the water sprinkler truck and pedestrians. The size of the detection box (10) is increased to 1.2 times. When the detection boxes after the increase in size overlap each other, it is determined that there is a risk of collision. At this time, the Alibaba Cloud server sends an alarm message to the vehicle terminal and controls the vehicle buzzer to sound.
