Description

Technical Field

[0001] The present invention relates to the technical field of industrial production management, and in particular to an automated production line maintenance system based on industrial interconnection. Background Art

[0002] Industrial production often requires the synergy of multiple links and technologies. At the same time, due to the pollution characteristics of industrial production, the environmental protection of industrial production is also crucial. In order to reduce industrial production costs and improve production line efficiency, modern production industries are constantly updating and iterating equipment, trying to develop high-tech to adapt to the coordination and environmental protection needs of production lines, and continuously promoting the sustainable development of the production industry.

[0003] In automated production, the production line realizes global transportation and material delivery automation by planning the production situation of the entire production line. However, due to the large proportion of raw material debris required for production, some raw materials will inevitably leak out during dumping, which not only causes waste but also harms the production line environment. A large amount of dust will be generated during dumping, and the splashing dust will affect the operating capacity of the production line equipment. In the prior art, a receiving hopper is used on the production line device for dumping raw materials to reduce the splashing of raw material dust. Although the dust collecting plate set on the receiving hopper largely avoids the problem of raw material leakage and large dust raised during dumping, the dust collecting plate greatly reduces the receiving area of ​​the receiving hopper, which seriously affects the receiving efficiency. Moreover, the dust collecting plate cannot consider the dust splashing under the influence of external wind. At the same time, the scheduled cleaning near the production line cannot meet the cleaning needs of different dumping amounts of raw materials. Therefore, it is necessary to design an automated production line maintenance system based on industrial interconnection with strong production line maintenance capabilities and high industrial planning degree. Summary of the invention

[0004] The purpose of the present invention is to provide an automated production line maintenance system based on industrial interconnection to solve the problems raised in the above background technology.

The dumping weight loss analysis submodule is used to monitor the dumping conditions of the loader at different dumping angles; the leakage rate analysis submodule is used to analyze the quality of raw materials leaked by the loader at different dumping angles.

[0009] According to the above technical solution, the dust monitoring module includes a dust quantity statistics module, a pollution degree analysis module and a wind force detection module.

[0010] According to the above technical solution, the output module includes a cleaning reminder module and a production line maintenance module. The cleaning reminder module is used to remind the staff to clean the leaked raw materials; the production line maintenance module is used to maintain the production line.

[0011] According to the above technical solution, the operation method of the automated production line maintenance system mainly includes the following steps:

[0012] Step S1: The loader bucket loaded with raw materials arrives near the feeding equipment, the camera module uses a camera arranged on the loader to capture the scene of the loader dumping the raw materials, and the raw material dumping monitoring module monitors the dumping process of the loader;

[0013] Step S2: The dumping weight loss analysis submodule obtains the amount of raw materials leaked each time the loader dumps the raw materials. When the leakage rate analysis submodule determines that the leakage amount reaches the pollution limit value, the cleaning reminder module reminds the relevant staff to clean the production line in time;

[0014] Step S3: The dust monitoring module monitors the dust generated by the loader during the dumping of raw materials in combination with the current wind force. When the pollution level analysis module determines that the dust accumulation has reached the production line maintenance limit, the production line maintenance module prompts the staff to maintain the production line.

[0015] According to the above technical solution, step S1 further includes:

[0016] Step S11: before dumping, the bucket is vertically upward, the initial tilt angle of the bucket center is 0°, the loading port gradually rotates to dump the loaded material outward, the angle detection submodule obtains the offset arc of the bucket center and the initial tilt angle as Z, where 0<Z<π, the distance detection submodule obtains the horizontal distance between the inner shovel of the loader bucket and the outer side of the material receiving device as E meters, the vertical distance between the node of the loader bucket and the lever arm connecting rod and the material receiving port as L meters, the average distance between the dumped material and the outer shovel of the loader bucket is W meters, and the loader rotates the bucket at a speed of V;

[0017] Step S12: When When the material in the bucket falls into the receiving device, the amount of material above the bucket during loading is added to the material above the centroid of the material in the bucket. The quality detection submodule obtains the mass of the material transported by the loader in a single time as M, and obtains the mass of the material under normal loading of the material through big data as m. The mass of the material above the bucket during bucket loading is m1=Mm. Since the internal structure of the bucket is approximately semicircular, the vertical distance between the centroid of the bucket and the line connecting the inner shovel opening and the outer shovel opening of the bucket is Where R is half the length of the shovel mouth, the area of ​​the material in the bucket that is higher than the centroid of the material is S1, and the mass

[0018]

[0019] The calculation formula for the area of ​​the raw material in the bucket that is higher than the centroid of the raw material is: Where X is the cross-sectional length of the raw material;

[0020] In During this period, the total mass of the material in the bucket falling into the receiving equipment is m3=m1+m2;

[0021] The speed of the raw material entering the receiving device at this time is set to V, and the time it takes for the raw material to reach the receiving port from the bucket Where g is the acceleration due to gravity, and the lateral distance that the raw material moves when it flies out of the bucket to the receiving port The leakage ratio

[0022] Step S13: When When , the amount of material in the bucket that falls into the receiving device is the remaining material above the node between the loader bucket and the lever arm connecting rod and the shovel connecting line outside the bucket, and the area of ​​the material is S2;

[0023] The calculation formula for the area S2 of the remaining raw materials above the node between the loader bucket and the lever arm connecting rod and the shovel line outside the bucket is:

[0024] In During this period, the quality of the raw materials in the bucket falling into the receiving equipment

[0025] The material is λ times the speed of the loader bucket. The lateral distance that the material moves from the inclined plate mouth to the receiving port Where λ is the compression speed conversion ratio, 1<λ≤2, the distance detection submodule obtains the horizontal distance between the inner shovel of the loader bucket and the outer side of the material receiving equipment as E meters, then the leakage ratio

[0026] Step S14: When When the material in the bucket falls into the receiving equipment, the amount of material is the remaining material. There is no leakage of this part of raw materials.

[0027] According to the above technical solution, in step S2, during the process of dumping the raw materials by the loader, the leakage rate analysis submodule obtains the total amount of raw materials leaked in a single time as M 总 =η1m3+η2m4, the leakage rate analysis submodule obtains the leakage volume M of the loader dumping the raw materials n times in sequence through the production volume collection module 总1 、M 总2 ……M 总n , and calculate the total leakage Q = M 总1 +M 总2 +......M 总n When Q>Q1, it is judged that the leaked raw materials will have a significant impact on the nearby environment and production equipment, where Q1 is affected by the surrounding land environment of the production equipment and the power of the production equipment, and is obtained by the production line environment acquisition module through big data.

[0028] According to the above technical solution, step S3 further includes:

[0029] Step S31: The wind force detection module detects the wind level every half an hour, obtains the wind level as X, and obtains the comprehensive average wind speed during dumping as A through the wind level. The quality detection submodule obtains the quality of the raw materials transported by the loader c times in turn, which are M1, M2...M c , then the total amount poured in half an hour G=M1+M2......M cWhen the raw materials are dumped, the dust quantity statistics module counts the dust quantity splashed by the wind during the dumping process of the raw materials under the influence of wind. Where λ is the unit conversion parameter;

[0030] Step S32: The pollution degree analysis module counts the dust quantities K1, K2, ..., K1 splashed out every half hour in sequence. 16 , and calculate the amount of dust accumulation near the production line when the wind force is small D = K1 + K2......K 16 If D>D1 and the average wind level is less than 3 during the statistical time period, the production line maintenance module will prompt the staff to maintain the production line, where D1 is the dust accumulation maintenance limit value of the raw material production line.

[0031] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention monitors the leakage of raw materials and dust generated by the loader dumping raw materials through the raw material monitoring module and the dust monitoring module, monitors the environment near the production line in real time, accurately determines the impact of pollutants on the production line and promptly prompts the staff to clean and maintain the production line, thereby improving the operating capacity of the production line and reducing the risk of production quality problems on the production line; at the same time, it improves the environmental safety issues near the production line and saves manpower.

[0042] The raw material dumping monitoring module further includes a dumping weight loss analysis submodule and a leakage rate analysis submodule. The dumping weight loss analysis submodule is used to monitor the dumping conditions of the loader at different dumping angles; the leakage rate analysis submodule is used to analyze the quality of raw materials leaked by the loader at different dumping angles.

[0043] The dust monitoring module includes a dust quantity statistics module, a pollution degree analysis module and a wind force detection module. The dust quantity statistics module is used to obtain the amount of dust splashed when the loader dumps raw materials under different wind forces; the pollution degree analysis module is used to analyze the pollution of the production line caused by the accumulation of dust near the production line; the wind force detection module is used to detect the current wind force through the production line environment collection module.

[0044] The output module includes a cleaning reminder module and a production line maintenance module. The cleaning reminder module is used to remind the staff to clean the leaked raw materials; the production line maintenance module is used to maintain the production line.

[0045] The operation method of the automated production line maintenance system mainly includes the following steps:

[0046] Step S1: The loader bucket 1 is loaded with raw materials and arrives near the feeding equipment. The camera module uses a camera arranged on the loader to capture the scene of the loader dumping the raw materials, and the raw material dumping monitoring module monitors the dumping process of the loader.

[0047] Step S2: The dumping weight loss analysis submodule obtains the amount of raw materials leaked each time the loader dumps the raw materials. When the leakage rate analysis submodule determines that the leakage amount reaches the pollution limit value, the cleaning reminder module reminds the relevant staff to clean the production line in time;

[0048] Step S3: The dust monitoring module monitors the dust generated by the loader during the dumping of raw materials in combination with the current wind force. When the pollution level analysis module determines that the dust accumulation has reached the production line maintenance limit, the production line maintenance module prompts the staff to maintain the production line.

[0049] Step S1 further comprises:

[0050] Step S11: before dumping, the bucket 1 is vertically upward, the initial tilt angle of the center of the bucket 1 is 0°, the loading port gradually rotates to dump the loaded material outward, the angle detection submodule obtains the offset arc of the center of the bucket 1 and the initial tilt angle as Z, where 0<Z<π, the distance detection submodule obtains the horizontal distance between the inner shovel 3 of the loader bucket and the outer side of the material receiving device as E meters, the vertical distance between the node 2 of the loader bucket 1 and the arm connecting rod and the material receiving port as L meters, the average distance between the dumped material and the outer shovel 4 of the loader bucket is W meters, and the loader rotates the bucket 1 at a speed of V;

[0051] Step S12: When When , the amount of material in bucket 1 that falls into the receiving device is the amount of material that is higher than bucket 1 during loading plus the material that is higher than the centroid of the material in bucket 1. The quality detection submodule obtains the mass of the material transported by the loader in a single time as M, and obtains the mass of the material under normal loading of the material through big data as m. Under normal loading of the material, the amount of material loaded in bucket (1) just exceeds bucket 1. When bucket 1 is loaded, the mass of the material higher than bucket 1 is m1=Mm. Since the internal structure of bucket 1 is approximately semicircular, the vertical distance between the centroid of bucket 1 and the line connecting the inner shovel opening and the outer shovel opening of the bucket is Where R is half the length of the shovel mouth, the area of ​​the material above the centroid of the material in the bucket 1 is S1, and the mass

[0052]

[0053] After the raw materials are crushed by the crusher, the density is uniform. The raw materials inside the bucket are regarded as a whole, and the centroid and center of gravity of the raw materials inside the bucket 1 are approximately coincident.

[0054] The centroid of a plane geometric figure is generally calculated using the method of equal static moments, that is, the total static moment of the figure is equivalent to the static moment of the centroid.

[0055] when In addition to the raw materials exceeding the horizontal plane of the bucket surface being poured into the material receiving equipment, due to the small dumping angle, the raw materials above the overall center of gravity of the raw materials inside the bucket will gradually fall into the material receiving equipment as the bucket rotates at a uniform speed, while the raw materials below the overall center of gravity of the raw materials inside the bucket will be blocked by the outer side of the bucket and will not fall into the material receiving equipment.

[0056] The calculation formula for the area of ​​the raw material in bucket 1 that is higher than the centroid of the raw material is: Where X is the cross-sectional length of the raw material;

[0057] In During this period, the total mass of the material in bucket 1 that falls into the receiving equipment is m3 = m1 + m2;

[0058] The bucket 1 rotates at an angle of In the case of , the upper raw material exerts less pressure on the lower raw material. The speed of the raw material entering the receiving device is set to V. The time it takes for the raw material to reach the receiving port from bucket 1 is Where g is the acceleration due to gravity, and the lateral distance that the raw material moves when it flies out of bucket 1 and reaches the receiving port The leakage ratio

[0059] Step S13: When When , the amount of material in bucket 1 that falls into the receiving device is the remaining material above the line connecting the node 2 between the loader bucket 1 and the lever arm connecting rod and the shovel 4 outside the bucket, and the area of ​​the material is S2;

[0060] The calculation formula for the area S2 of the remaining raw materials above the connection line between the loader bucket 1 and the lever arm link node 2 and the bucket outer shovel 4 is: There is a small overlap between S1 and S2, but since the ratio of the overlapping area is small, it is within the reasonable error range of the calculation and has little impact on the calculation accuracy.

[0061] In During this period, the mass of the raw materials in bucket 1 falling into the receiving equipment

[0062] The bucket 1 rotates at an angle of In the case of the material above exerting greater pressure on the material below, the material is λ times the speed of the loader bucket (1), and the lateral distance traveled by the material from the inclined plate mouth to the material receiving port is Where λ is the compression speed conversion ratio, 1<λ≤2, the distance detection submodule obtains the horizontal distance between the inner shovel 3 of the loader bucket and the outer side of the material receiving equipment as E meters, then the leakage ratio

[0063] Step S14: When When the material in bucket 1 falls into the receiving device, the amount of material is the remaining material. There is no leakage of this part of raw materials.

[0064] When considering the leakage ratio, there is no need to consider the width of bucket 1, because the area of ​​bucket 1 is smaller than the material receiving equipment, and the dumping conditions of all materials on the width of bucket 1 are basically the same, so the dumping conditions of materials in the entire bucket 1 can be deduced by studying the dumping conditions of raw materials in a cross section.

[0065] The raw material monitoring module analyzes the leakage of raw materials within three continuous dumping angles during the loader's uniform dumping of raw materials. Since there are great differences in the dumping conditions of the raw materials inside the bucket during the dumping process, the classification and calculation of the leakage of raw materials is more accurate than the existing technology for monitoring the entire dumping process. At the same time, the internal raw material loading structure of the loader obtained during the dumping calculation process further helps the staff to judge the loading capacity of each loader for loading raw materials through the leakage amount when calculating the quality of the raw materials, providing a favorable basis for detecting the loader's transportation efficiency.

[0066] In step S2, in the process of dumping raw materials by the loader in a single time, the leakage rate analysis submodule obtains the total amount of raw materials leaked in a single time as M 总 =η1m3+η2m4, the leakage rate analysis submodule obtains the leakage volume M of the loader dumping the raw materials n times in sequence through the production volume collection module 总1 、M 总2 ……M 总n , and calculate the total leakage Q = M 总1 +M 总2 +......M 总n When Q>Q1, it is judged that the leaked raw materials will have a significant impact on the nearby environment and production equipment, where Q1 is affected by the surrounding land environment of the production equipment and the power of the production equipment, and is obtained by the production line environment acquisition module through big data.

[0067] Step S3 further comprises:

[0068] Step S31: The wind force detection module detects the wind level every half an hour, obtains the wind level as X, and obtains the comprehensive average wind speed during dumping as A through the wind level. The quality detection submodule obtains the quality of the raw materials transported by the loader c times in turn, which are M1, M2...M c , then the total amount poured in half an hour G=M1+M2......M c When the raw materials are dumped, the dust quantity statistics module counts the dust quantity splashed by the wind during the dumping process of the raw materials under the influence of wind. Where λ is the unit conversion parameter;

[0069] Step S32: The pollution degree analysis module counts the dust quantities K1, K2, ..., K1 splashed out every half hour in sequence. 16 , and calculate the amount of dust accumulation near the production line when the wind force is small D = K1 + K2......K 16 If D>D1 and the average wind level is less than 3 during the statistical time period, the production line maintenance module will prompt the staff to maintain the production line, where D1 is the dust accumulation maintenance limit value of the raw material production line.

[0070] The preset working time of the loader is 8 hours per day, that is, the number of dust counts per day is 16 times.

[0071] When the wind speed is low, the amount of dust splashed when pouring raw materials is small. The value is small; when the wind level gradually increases, the amount of dust splashed will increase rapidly due to the increase in wind speed. The value soared.

[0072] The dust monitoring module calculates the amount of dust generated by the loader dumping raw materials under the influence of different wind forces. According to the huge difference in the degree of dust splashing under the influence of different wind levels, the amount of splashed dust is obtained through the change of the base of wind speed and the exponential transformation of wind level. This solves the difficulty of capturing the amount of dust and helps the system accurately obtain the real-time pollution situation of the production line.

The quality detection submodule obtains the quality of the raw materials transported by the loader c times in turn, which are M1, M2...M c , then the total amount poured in half an hour G=M1+M2......M c When the raw materials are dumped, the dust quantity statistics module counts the dust quantity splashed by the wind during the dumping process of the raw materials under the influence of wind. Where λ is the unit conversion parameter; Step S32: The pollution degree analysis module counts the dust quantities K1, K2, ..., K1 splashed out every half hour in sequence. 16 , and calculate the amount of dust accumulation near the production line when the wind force is small D = K1 + K2......K 16 If D>D1 and the average wind level is less than 3 during the statistical time period, the production line maintenance module will prompt the staff to maintain the production line, where D1 is the dust accumulation maintenance limit value of the raw material production line.
