Description

Technical Field

[0001] This invention relates to the field of conveyor control technology, specifically to a control method for improving the continuous operation of a conveyor. Background Technology

[0002] Conveyors are widely used in mining, building materials, grain processing and material transfer scenarios. In application environments that include ramp conveyor sections, materials need to be continuously transported by the interaction between the conveyor belt and the materials. Existing conveyors are usually controlled according to operating parameters such as conveyor belt speed, conveying load and inlet feed rate to maintain the stability of the material conveying process. In actual ramp conveying processes, after entering the ramp, materials at different heights may exhibit different motion states due to their own weight, the movement of the conveyor belt, and the slope conditions. The movement of some materials in the upper area is not entirely consistent with that of materials near the conveyor belt bearing surface in the conveying direction, which may result in differences in the passage time of the same batch of materials between the inlet detection position, the slope weighing position, and the outlet detection position. For the accumulation state of materials with varying height distribution, it is difficult to distinguish the actual passage of materials in different height areas based solely on the overall conveying volume or a single weighing result. Existing conveying control methods can adjust the conveying process by detecting changes in conveying volume, weight, and operating parameters. However, in the case of ramp conveying, there is a certain correlation between the material's passage status and the weighing result. It is necessary to further consider the material's distribution in the height direction and the conveying process corresponding to different height areas. How to establish the correspondence between the material's height range and weight change using the detection data of the inlet, outlet, and ramp positions, and adjust the conveying process according to the actual passage situation in different height ranges, is a problem that needs to be solved in improving the continuous operation capability of ramp conveying. Therefore, this invention proposes a control method to improve the continuous operation of conveyors. Summary of the Invention

[0003] The purpose of this invention is to provide a control method for continuous operation of a lifting conveyor, so as to solve the problems mentioned in the background art.

[0004] This invention can be achieved through the following technical solution: a control method for continuous operation of a hoisting conveyor, comprising: Step 1: Read the inlet detection section data, determine the material section entering the ramp according to the preset bearing surface height reference, and determine the first height range and the second height range above the first height range in the material section according to the preset height division. Extract the inlet side material morphology features formed by height change, edge distribution and particle agglomeration within the first height range and the second height range respectively. Step 2: Based on the start and end positions of the material section's conveying direction and the actual displacement of the conveyor belt, determine the estimated arrival time of the material section at the outlet detection section; Step 3: Read the exit detection section data within the expected arrival time period, and extract the material morphology characteristics of the exit side within the first and second height ranges; match the material morphology characteristics of the inlet side within the same height range with the material morphology characteristics of the exit side, and determine the height range that has been passed and the height range that has not been passed by in combination with the actual exit throughput. Step 4: Determine the weighing time period corresponding to the weighing position of the slope section through which the material section passes according to the actual displacement of the conveyor belt. Read the slope weighing value and the cross-sectional height data at the slope weighing position within the weighing time period. Determine the relative size of the occupancy of the first height range and the second height range within the weighing time period based on the cross-sectional height data, and allocate the slope weighing value according to the relative size of the occupancy. Include the allocated weighing value corresponding to the height range that has been passed into the effective conveying weight value, and include the allocated weighing value corresponding to the height range that has not been passed into the residual weight value. Step 5: Generate the inlet feed adjustment amount and conveyor belt speed adjustment amount according to the height range corresponding to the retention weight value, and adjust the inlet feed and conveyor belt operation status accordingly.

[0005] A further technical improvement of the present invention is that: step one, extracting the morphological characteristics of the material on the inlet side, includes: During the process of material passing through the inlet detection section, multiple sets of inlet detection section data are read according to the sampling time, and each sampling time is corresponding to the sampling section position arranged along the conveying direction according to the actual displacement of the conveyor belt. Within the first and second height ranges, the height distribution is read from the entrance detection section data corresponding to each sampling section location, and the height distribution is converted into a relative height distribution based on the preset bearing surface height reference. Within the same height range, the lateral sampling positions corresponding to the material coverage are determined based on the relative height distribution. The lateral start and end positions are determined according to the lateral sampling sequence, and the edge distribution is formed by the lateral start and end positions. The location range of the particle agglomerates is determined based on the distribution relationship of the lateral sampling positions corresponding to the material coverage in the lateral sampling sequence, and the particle agglomerate arrangement is formed according to the arrangement order and adjacent intervals of the location range in the sampling section position sequence. Within the same height range, height changes are formed based on the relative height distribution corresponding to adjacent sampling section positions along the conveying direction, and data that only corresponds to a single sampling section position and does not form a corresponding height change with adjacent sampling section positions are not included in the formation of height changes; Within the same height range, the edge distribution and particle agglomeration arrangement are correlated with the height change according to the order of sampling section positions to form the inlet-side material morphology characteristics corresponding to the first height range and the second height range, respectively.

[0006] A further technical improvement of the present invention is that step two, determining the expected arrival time, includes: Read the distance along the conveying direction from the inlet detection section to the outlet detection section, and the actual displacement of the conveyor belt saved at each time point; Within the first and second height ranges, the sampling section positions associated with the material morphology characteristics on the inlet side are read respectively, and the sampling section positions located at the beginning and end along the conveying direction within each height range are determined according to the order of the sampling section positions. The sampling times corresponding to the foremost and last sampling sections along the conveying direction within each height range are taken as the starting times. The time when the actual cumulative displacement of the conveyor belt reaches the distance from the inlet detection section to the outlet detection section along the conveying direction is determined, and the arrival start point and arrival end point corresponding to each height range are formed respectively. The earlier time among the arrival starting points corresponding to the first height range and the second height range is taken as the starting point of the expected arrival period of the material section to the outlet detection section, and the later time among the arrival ending points corresponding to the first height range and the second height range is taken as the ending point of the expected arrival period.

[0007] A further technical improvement of the present invention lies in: the step of matching the morphological characteristics of the inlet-side material with the morphological characteristics of the outlet-side material within the same height range in step three includes: Read the arrival start point and arrival end point corresponding to the first height range and the second height range respectively, and read the exit detection section data within the arrival start point to arrival end point of the corresponding height range; Based on the sampling time of the exit detection section data and the actual displacement of the conveyor belt, each sampling time is corresponding to the sampling section position on the exit side arranged along the conveying direction, and relative height distribution, edge distribution, particle agglomeration arrangement and height change are formed within the corresponding height range; Based on the sequential relationship of the sampling section locations on the outlet side, the relative height distribution, edge distribution, particle agglomeration arrangement, and height variation are correlated to form the material morphology characteristics on the outlet side within the corresponding height range; Within the same height range, based on the sequential relationship between the sampling section positions associated with the material morphology characteristics on the inlet side and the sampling section positions on the outlet side, the height variation, edge distribution, and particle agglomeration arrangement of the material morphology characteristics on the inlet side and the outlet side are compared. When the order of height changes within the same height range is consistent, the lateral start and end positions of the edge distribution correspond, and the front and back order of the particle clusters correspond, a matching result is formed for that height range; when any one of the height changes, edge distribution, or particle clusters does not correspond, an unmatched result is formed for that height range. The matching and unmatched results are used to determine the pass / fail status of the corresponding height range.

[0008] A further technical improvement of the present invention is that the step of determining the passed height range and the unpassed height range in step three, based on the actual exit throughput, includes: Read the exit throughput data within the expected arrival period, generate the actual exit throughput based on the exit throughput data, and read one of the matching results and unmatched results generated for the first height range and the second height range respectively; During the expected arrival period, based on the relative height distribution of the exit side corresponding to the first height range and the second height range, the occupancy value of the height range corresponding to the material coverage is accumulated respectively, forming the cumulative occupancy value of the exit side corresponding to the first height range and the cumulative occupancy value of the exit side corresponding to the second height range. Based on the ratio between the cumulative exit occupancy value corresponding to the first height range and the cumulative exit occupancy value corresponding to the second height range, the actual exit throughput is allocated to the first height range and the second height range to form the height range throughput corresponding to each height range. Based on the relative height distribution of the first and second height ranges formed by the material section at the inlet detection section, the cumulative occupancy value of the inlet side corresponding to the first height range and the cumulative occupancy value of the inlet side corresponding to the second height range are determined respectively, and the reference throughput of the corresponding height range is determined based on the cumulative occupancy value of the inlet side corresponding to each height range. The throughput of the same height range is compared with the reference throughput to form the throughput level corresponding to that height range. Within the same height range, when the corresponding matching result for that height range meets the preset passing requirements, that height range is determined as the passed height range; Within the same height range, if there is no matching result within that height range, that height range is determined as an unpassed height range. Within the same height range, if the matching result for that height range does not meet the preset passing requirements, that height range is determined as the failing height range.

[0009] A further technical improvement of the present invention is that the step of allocating the weighing value of the slope section according to the relative size of the occupancy in step four includes: During the weighing period, the cross-sectional height data at the weighing location of the slope section is read according to the collection time of the slope section weighing value, and relative height distribution at the weighing location of the slope section corresponding to each collection time is formed in the first height range and the second height range based on the preset bearing surface height reference. The first height range and the second height range are processed separately. The relative height value corresponding to the material coverage within the corresponding height range is read according to the lateral sampling position. The relative height values ​​of each lateral sampling position are accumulated at the same collection time to form the occupancy of the corresponding height range at that collection time. The occupancy amounts corresponding to the first height range and the second height range within the same collection time are added together to form the total occupancy value for that collection time. Based on the proportion of the occupancy amount corresponding to the first height range in the total occupancy value and the proportion of the occupancy amount corresponding to the second height range in the total occupancy value, the slope section weighing value within the sampling period corresponding to that collection time is allocated, forming the weighting values ​​allocated to the first height range and the second height range for that collection time. Within the corresponding weighing time period, the weight values ​​allocated at the collection times corresponding to the first height range and the second height range are accumulated respectively to form the allocated weight values ​​corresponding to the first height range and the allocated weight values ​​corresponding to the second height range.

[0010] A further technical improvement of the present invention is that the step of including the effective transport weight value and the stagnant weight value in step four includes: Read the allocated weighing values ​​for the height range that has been passed, the height range that has not been passed, the first height range, and the second height range; The weight values ​​allocated to those already passed within the first and second height ranges are included in the effective transport weight value. The weight values ​​allocated to those not passing the height range within the first and second height ranges are included in the stagnant weight value.

[0011] A further technical improvement of the present invention is that the step of generating the inlet feed adjustment amount and the conveyor belt speed adjustment amount in step five includes: Read the allocated weighing value that includes the retained weight; According to the height range to which the assigned weighing value belongs, the assigned weighing values ​​belonging to the first height range and the assigned weighing values ​​belonging to the second height range are accumulated respectively to form the residual weight value corresponding to the first height range and the residual weight value corresponding to the second height range; when there is no assigned weighing value in the corresponding height range, the residual weight value of the corresponding height range is recorded as zero. Add the weight values ​​of the first height range and the weight values ​​of the second height range together to form the total weight value of the retention. When the total value of the retained weight is greater than zero, the degree of operation adjustment is determined based on the total value of the retained weight, and the first retention ratio of the retained weight value corresponding to the first height range in the total value of the retained weight and the second retention ratio of the retained weight value corresponding to the second height range in the total value of the retained weight are determined. The system reads the range within which the conveyor belt speed can be reduced and the range within which the inlet feed can be reduced. Based on the degree of operational adjustment and the first retention ratio, the system determines the amount of conveyor belt speed adjustment within the range within which the conveyor belt speed can be reduced. Based on the degree of operational adjustment and the second retention ratio, the system determines the amount of inlet feed adjustment within the range within which the inlet feed can be reduced. Reduce the conveyor belt speed according to the adjustment amount, and reduce the inlet feed according to the adjustment amount.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention distinguishes different reading ranges in the height direction for the same material section, so that the material status information formed at the inlet detection position can correspond to different height ranges in the subsequent conveying process, providing a data basis for subsequent judgment on whether the material in different areas has been conveyed. Furthermore, by comparing the material morphology information on the inlet side with the detection results on the outlet side, and combining the outlet throughput to determine the throughput of different height ranges, the present invention enables the weight information obtained during the slope weighing process to be assigned according to the height range, thereby reducing the problem that the overall weighing results cannot reflect the local conveying status. On the other hand, the present invention generates corresponding operating adjustment amounts based on the retention weight conditions corresponding to different height ranges, so that the inlet feeding adjustment and conveyor belt operation adjustment can be processed based on specific retention areas, thereby improving the pertinence of the operating status adjustment during ramp conveying and ensuring continuous operation of the conveying process. Attached Figure Description

[0013] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0014] Figure 1 This is a schematic diagram of the method logic of the present invention. Detailed Implementation

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0016] Please see Figure 1 As shown, the present invention provides a control method for continuous operation of a hoisting conveyor, comprising: Step 1: Read the inlet detection section data, determine the material section entering the ramp according to the preset bearing surface height reference, and determine the first height range and the second height range above the first height range in the material section according to the preset height division. Extract the inlet side material morphology features formed by height change, edge distribution and particle agglomeration within the first height range and the second height range respectively. Specifically, in this embodiment, the conveyor is used to transport materials along the conveyor belt to the ramp area. An inlet detection section is set at a position before the material enters the ramp, used to collect cross-sectional height data when the material passes through this position. Multiple transverse sampling positions are set along the width direction of the conveyor belt at the inlet detection section, and these transverse sampling positions are arranged sequentially according to the width direction of the conveyor belt, forming a transverse sampling sequence. The inlet detection section data is formed by the height values ​​corresponding to each transverse sampling position at the same sampling time, used to describe the height distribution of the material as it passes through the inlet detection section.

[0017] Before material inspection, the cross-sectional height data of the conveyor belt during unloaded operation is read at the inlet inspection section, the slope weighing position, and the outlet inspection section. Multiple transverse sampling positions are set along the width of the conveyor belt at each inspection location. The height of the conveyor belt bearing surface at that location is determined based on the continuously collected unloaded height values ​​from the same transverse sampling position. The conveyor belt bearing surface heights corresponding to each transverse sampling position are arranged in the transverse sampling order to form reference heights for the bearing surface at the inlet inspection section, the slope weighing position, and the outlet inspection section.

[0018] When reading the cross-sectional height data laterally, the corresponding bearing surface height reference is read according to the detection position to which the data belongs, and the detection height of each transverse sampling position is converted into the relative height of the conveyor belt bearing surface at that position.

[0019] The preset height division positions are established during the equipment commissioning phase. Under normal conveying conditions, multiple sets of inlet detection section data are read, and each set of inlet detection section data is converted into a relative height distribution based on the corresponding bearing surface height reference. The material layer height distribution is then formed based on these multiple relative height distributions, and the preset height division positions are determined accordingly. Once established, the preset height division positions are saved as fixed height division parameters.

[0020] In this embodiment, the allowable material layer height range is predetermined based on the allowable material accumulation height of the conveyor in the ramp conveying state. Its upper boundary is higher than the preset height division position and serves as the upper limit of the second height range.

[0021] The first height range is defined as the height interval between the relative height zero point corresponding to the conveyor belt bearing surface and the preset height division position. The second height range is defined as the height interval above the preset height division position but within the allowable conveying material layer height range. After the cross-sectional height data of the inlet detection section, the slope weighing position, and the outlet detection section are converted into relative heights, the first and second height ranges are determined according to the same preset height division position.

[0022] Once the material enters the inlet detection section, the inlet detection section data is read according to the sampling time, and the actual displacement of the conveyor belt is acquired simultaneously. The actual displacement of the conveyor belt is formed by the displacement detection data during the operation of the conveyor belt. The displacement detection data is saved according to the sampling time, so that each sampling time corresponds to an actual displacement value of the conveyor belt. Taking the sampling time when the material first enters the inlet detection section as the starting sampling time, the inlet detection section data read at different sampling times are converted into sampling section positions arranged along the conveying direction based on the actual displacement of the conveyor belt corresponding to subsequent sampling times.

[0023] After establishing the sampling section locations, the material section is determined based on the inlet detection section data. Specifically, the inlet detection section data corresponding to each sampling time is converted into a relative height distribution, and the presence of material coverage at each lateral sampling location is determined based on the first and second height ranges. When a lateral sampling location forms a non-zero height portion within the current height range, that lateral sampling location is identified as a material coverage location within the current height range; when a lateral sampling location does not form a non-zero height portion within the current height range, that lateral sampling location is not identified as a material coverage location within the current height range.

[0024] The material coverage position at each sampling time is read according to the sampling time sequence. When there is a material coverage position in the inlet detection section data corresponding to adjacent sampling times, the data of the corresponding sampling times are grouped into the same material segment; when there is no material coverage position in the inlet detection section data corresponding to the sampling time, the data merging of the current material segment ends. The material segment is formed by the inlet detection section data corresponding to consecutive sampling times, the sampling section position, and the actual displacement of the conveyor belt. The starting position of the material segment along the conveying direction is determined by the position of the foremost sampling section along the conveying direction, and the ending position is determined by the position of the last sampling section along the conveying direction.

[0025] After determining the material section, the height range of the inlet detection section data corresponding to each sampling section location is divided. Specifically, the height value corresponding to each transverse sampling position is subtracted from the preset bearing surface height reference at the corresponding position to form a relative height value; the relative height values ​​corresponding to each transverse sampling position in the same sampling section location collectively form a relative height distribution.

[0026] For the first and second height ranges, the relative height distribution within each range is read. For any lateral sampling position, if the relative height value at that position forms a non-zero height portion within the current height range, that lateral sampling position is determined as a material coverage position within the current height range; if the relative height value at that position does not form a non-zero height portion within the current height range, that lateral sampling position is not determined as a material coverage position within the current height range. When the relative height value at that position exceeds the upper boundary of the current height range, only the height portion within the current height range is read to participate in the formation of the relative height distribution within the current height range.

[0027] Within the same height range, the lateral sampling positions corresponding to material coverage are determined based on the relative height distribution, and the lateral start and end positions are determined according to the lateral sampling order. The lateral sampling position where material coverage first appears within the current height range is determined as the lateral start position, and the lateral sampling position where material coverage last appears is determined as the lateral end position. The lateral start and end positions corresponding to multiple sampling sections are arranged according to the order of the sampling sections to form an edge distribution.

[0028] The location range of particle clumps is determined based on the distribution relationship of the lateral sampling positions corresponding to the material coverage in the lateral sampling sequence. Specifically, lateral sampling positions with consecutive numbers that all correspond to the material coverage in the lateral sampling sequence are divided into the same location range, and particle clumps are arranged according to the arrangement order of each location range in different sampling sections and the interval relationship between adjacent location ranges.

[0029] Within the same height range, height variation is formed based on the relative height distribution corresponding to adjacent sampling section positions along the conveying direction. Specifically, adjacent sampling section positions are read according to their sequential relationship, and the relative height values ​​corresponding to the same lateral sampling positions are compared. When the same lateral sampling position exists in both adjacent sampling section positions, the height variation is formed based on the change in the relative height value of the later sampling section position relative to the relative height value of the earlier sampling section position. Data that corresponds to only a single sampling section position and does not form a corresponding relative height value in adjacent sampling section positions does not participate in the formation of height variation.

[0030] Within the same height range, edge distribution, particle agglomeration arrangement, and height changes are correlated according to the order of sampling section positions. Specifically, using the sampling section position as the correlation position, the edge distribution, particle agglomeration arrangement, and height changes between adjacent sampling section positions corresponding to the same sampling section position are correlated to form the inlet-side material morphology characteristics corresponding to the first height range and the inlet-side material morphology characteristics corresponding to the second height range.

[0031] The resulting inlet-side material morphology features include the corresponding height range, sampling section position, and conveying direction arrangement, which are used for matching the material morphology within the same height range at the subsequent outlet detection section.

[0032] Step 2: Based on the start and end positions of the material section's conveying direction and the actual displacement of the conveyor belt, determine the estimated arrival time of the material section at the outlet detection section; Specifically, after the material morphology characteristics are formed on the inlet side, this embodiment determines the expected arrival time of the material section to the outlet detection section based on the sampling section position corresponding to the material morphology characteristics on the inlet side and the actual displacement of the conveyor belt.

[0033] In this embodiment, the preset sampling period is determined during the equipment debugging phase based on the sampling frequency of the inlet detection section and the running speed of the conveyor belt, so that the material positions corresponding to adjacent sampling times can be continuously arranged along the conveying direction.

[0034] During the inlet detection section data acquisition process, inlet detection section data is acquired according to a preset sampling period, and the actual displacement of the conveyor belt at the corresponding sampling time is acquired simultaneously. The actual displacement of the conveyor belt is formed by the displacement detection data during the operation of the conveyor belt. The displacement detection data is indexed and saved according to the sampling time, and each sampling time corresponds to a cumulative displacement value. This cumulative displacement value represents the cumulative distance moved by the conveyor belt from the starting point of the position calculation to the corresponding sampling time, and is recorded in units of length.

[0035] The difference in cumulative displacement values ​​between adjacent sampling times forms the actual displacement change of the conveyor belt within that adjacent time period. The actual displacement change of the conveyor belt is used to describe the positional change of the material section along the conveying direction between adjacent sampling times; the cumulative displacement value is used to determine whether the sampling section has moved to the outlet detection section.

[0036] When the material section first passes the inlet detection section, the corresponding sampling time is determined as the starting point for position calculation. The cumulative displacement value corresponding to this position calculation starting point is used as the initial value for spatial position calculation. Based on the changes in the cumulative displacement values ​​at subsequent sampling times, the conveying direction position corresponding to different sampling times is determined.

[0037] Based on the position of the conveying direction at each sampling time, the inlet detection section data are arranged according to the sequence of the conveying direction, and the data position corresponding to each sampling time is determined as the sampling section position. The sampling section position and the sampling time are kept in correspondence, so that the corresponding sampling time and the cumulative displacement value at that time can be read at each sampling section position.

[0038] The distance from the inlet detection section to the outlet detection section along the conveying direction is determined during the equipment installation phase. This distance represents the fixed conveying distance required for any sampling section position in the material section to move from the inlet detection section to the outlet detection section. Subsequently, by comparing the cumulative displacement change after the corresponding starting time of the sampling section position with this fixed conveying distance, the time for the sampling section position to reach the outlet detection section is determined.

[0039] For the first height range, the sampling section position corresponding to the first height range in the material morphology characteristics on the inlet side is read, and sorted according to the cumulative displacement value corresponding to the sampling section position.

[0040] The position of the foremost sampling section along the conveying direction within the first height range is taken as the foremost sampling section position corresponding to the first height range, and the position of the last sampling section along the conveying direction is taken as the last sampling section position corresponding to the first height range.

[0041] The sampling time corresponding to the position of the foremost sampling section is read and used as the starting time for calculating the arrival time corresponding to the first height range. The cumulative displacement value changes saved after this starting time are accumulated. When the cumulative actual displacement change of the conveyor belt first reaches the fixed conveying distance from the inlet detection section to the outlet detection section, the corresponding sampling time is determined as the arrival starting point corresponding to the first height range.

[0042] Read the sampling time corresponding to the last sampling section position, and determine the arrival point corresponding to the first height range in the same way.

[0043] In the above manner, the first height range forms a corresponding arrival start point and arrival end point, where the arrival start point indicates the time position at which the material in the first height range begins to arrive at the outlet detection section, and the arrival end point indicates the time position at which the material in the first height range completes its arrival at the outlet detection section.

[0044] For the second height range, the sampling section position corresponding to the second height range is read from the material morphology characteristics on the inlet side, and the position of the foremost sampling section and the position of the last sampling section corresponding to the second height range are determined according to the cumulative displacement value corresponding to the sampling section position, in the same way as the first height range.

[0045] The starting time is taken as the sampling time corresponding to the first and last sampling sections of the second height range, respectively. Based on the comparison between the cumulative displacement change after the corresponding time and the fixed conveying distance from the inlet detection section to the outlet detection section, the arrival start point and arrival end point of the second height range are determined.

[0046] Thus, the first altitude range and the second altitude range respectively form the corresponding starting point and ending point of arrival.

[0047] Since the first height range and the second height range belong to different reading ranges in the height direction of the same material section, the distribution of the sampling section positions corresponding to the two height ranges in the conveying direction may be different. Therefore, it is necessary to determine the arrival time ranges corresponding to the two height ranges separately to cover the process of different height ranges of the same material section reaching the outlet detection section.

[0048] The arrival times of the first and second altitude ranges are compared, and the earlier arrival time is determined as the start of the expected arrival period. The arrival times of the first and second altitude ranges are compared, and the later arrival time is determined as the end of the expected arrival period.

[0049] The expected arrival time is formed by the start and end points of the expected arrival time. The expected arrival time is used to define the data reading range of the exit detection section.

[0050] During the data collection process at the exit inspection section, the start time of the expected arrival period is taken as the start time for reading the exit inspection section data, and the end time of the expected arrival period is taken as the end time for reading the exit inspection section data. The exit inspection section data is only read within the expected arrival period, and the material morphology characteristics on the exit side are extracted according to the first height range and the second height range, respectively.

[0051] Step 3: Read the exit detection section data within the expected arrival time period, and extract the material morphology characteristics of the exit side within the first and second height ranges; match the material morphology characteristics of the inlet side within the same height range with the material morphology characteristics of the exit side, and determine the height range that has been passed and the height range that has not been passed by in combination with the actual exit throughput. Specifically, after the expected arrival time period is formed, the exit detection section is used to read the material status passing through the exit position within the corresponding height range. In this embodiment, the arrival start point and arrival end point corresponding to the first height range and the second height range are read, and the exit detection section data are read according to the time range corresponding to each height range.

[0052] The data reading time range for the exit detection section corresponding to the first height range is determined by the arrival start and arrival end points corresponding to the first height range, and the data reading time range for the exit detection section corresponding to the second height range is determined by the arrival start and arrival end points corresponding to the second height range. The exit detection section data is read according to its own corresponding time range for each height range, and the correspondence between the sampling time and the exit detection section data is saved according to the corresponding height range.

[0053] During the data acquisition process at the exit inspection section, the actual displacement of the conveyor belt at the corresponding sampling time is read synchronously. The actual displacement of the conveyor belt is stored in the same data format as that at the inlet inspection section, that is, the corresponding cumulative displacement value is stored using the sampling time as an index, and the change in actual displacement of the conveyor belt within the corresponding time range is determined based on the difference between the cumulative displacement values ​​at adjacent sampling times.

[0054] Based on the sampling time of the outlet inspection section data and the corresponding actual displacement change of the conveyor belt, the position along the conveying direction corresponding to each sampling time is determined, and the sampling section positions on the outlet side are arranged according to the sequential relationship of the conveying direction. The sampling section positions on the outlet side are kept correlated with the corresponding sampling time, so that the outlet inspection section data can be arranged according to the material movement direction.

[0055] When processing the exit inspection section data, the preset height division position determined by the entrance inspection section is used to read the height data of the first height range and the second height range respectively.

[0056] For the first height range, the relative height distribution of the exit side corresponding to the first height range is formed based on the exit detection section height data and the preset bearing surface height reference.

[0057] Based on the relative height distribution of the exit side corresponding to the first height range, read the lateral sampling positions where the relative height values ​​satisfy the height conditions of the first height range, and determine the lateral start and end positions corresponding to the height range according to the lateral sampling order. The lateral start and end positions form the exit side edge distribution corresponding to the first height range.

[0058] Based on the arrangement of the lateral sampling positions within the first height range along the lateral sampling sequence, the range of locations where material coverage exists continuously is determined. Combining the sequential arrangement of this range in the sampling section on the outlet side and the interval between adjacent positions, the arrangement of particle clumps on the outlet side corresponding to the first height range is formed.

[0059] For the height change on the exit side within the first height range, the relative height distribution on the exit side corresponding to adjacent sampling section positions is read according to the order of sampling section positions on the exit side, and the change in relative height value corresponding to the same lateral sampling position is compared.

[0060] When the relative height value corresponding to the sampling section position of the next exit side forms a change relationship with the relative height value corresponding to the sampling section position of the previous exit side, the corresponding change relationship is taken as the exit side height change corresponding to the first height range; data that only exists at a single exit side sampling section position and does not form a corresponding change relationship at adjacent exit side sampling section positions are not included in the formation of the exit side height change of the first height range.

[0061] The second height range uses the same processing method to form the corresponding material morphology characteristics on the outlet side.

[0062] Specifically, data from the outlet detection section is read within the time range corresponding to the second height range. The relative height distribution of the outlet side corresponding to the second height range is formed based on the preset bearing surface height reference. The edge distribution of the outlet side is formed based on the transverse sampling position corresponding to the second height range. The arrangement of particle agglomerates on the outlet side is formed based on the arrangement of material coverage positions along the transverse sampling sequence within the second height range and the sequential relationship of the sampling section positions on the outlet side. The change in the height of the outlet side corresponding to the second height range is formed based on the change in the relative height distribution corresponding to the sampling section positions on adjacent outlet sides.

[0063] Therefore, the exit detection section forms the material morphology characteristics on the exit side corresponding to the first height range and the second height range, respectively.

[0064] The material morphology characteristics of the outlet side and the material morphology characteristics of the inlet side are divided by the same height range, the same feature composition, and the same position arrangement, so that the material morphology characteristics formed at the two detection positions can be compared within the same height range.

[0065] Within the same height range, the material morphology characteristics on the inlet side are matched with those on the outlet side.

[0066] During the specific matching process, the height variation, edge distribution, and particle agglomeration arrangement in the material morphology characteristics on the inlet side are read, and the height variation, edge distribution, and particle agglomeration arrangement in the corresponding height range on the outlet side are also read.

[0067] According to the sequential relationship between the sampling section positions on the inlet side and the sampling section positions on the outlet side along the conveying direction, the corresponding sampling section positions within the two height ranges are arranged.

[0068] In this embodiment, the preset allowable range for height variation, the preset allowable range for edge position, and the preset allowable range for interval are determined during the equipment commissioning phase. During commissioning, the material section is made to pass through the inlet detection section and the outlet detection section in a normal conveying state. The height variation difference, the lateral start and end position difference, and the difference in the interval between adjacent particles within the same height range are obtained. The preset allowable range for height variation, the preset allowable range for edge position, and the preset allowable range for interval are determined based on the range of differences formed under normal conveying state.

[0069] For height changes, the relative height change direction and amount are compared between adjacent sampling sections on the inlet and outlet sides according to the order of sampling section positions. When the change direction is consistent and the difference in amount of change is within the preset allowable range of height change, the height change is determined to be corresponding.

[0070] For edge distribution, compare the lateral start position and lateral end position of the corresponding sampling section positions on the inlet side and the outlet side. When the difference between the lateral start position and the lateral end position is within the preset edge position allowable range, the edge distribution is determined to be corresponding.

[0071] For particle cluster arrangement, compare the arrangement order and adjacent intervals formed by the sequential relationship of each position range along the sampling section. When the arrangement order is consistent and the difference between adjacent intervals is within the preset interval allowable range, the particle cluster arrangement is determined to be corresponding.

[0072] When the height variation, edge distribution, and particle cluster arrangement within the same height range all correspond, a matching result is formed for that height range; when any one of them does not correspond, an unmatched result is formed for that height range.

[0073] Export throughput data is saved according to the sampling time. In this embodiment, export throughput is expressed as material weight. The corresponding export throughput data is accumulated within the expected arrival time period to form the actual export throughput.

[0074] Within the expected arrival time period, the relative height distribution on the exit side corresponding to the first and second height ranges are read respectively. For each sampling time, the height portion belonging to the corresponding height range is accumulated according to the lateral sampling position to form the cross-sectional occupancy value of the corresponding height range, and combined with the actual displacement of the conveyor belt between adjacent sampling times to form the height range occupancy value.

[0075] The occupancy values ​​of the first and second height ranges are accumulated respectively to form the cumulative occupancy value of the exit side corresponding to the first height range and the cumulative occupancy value of the exit side corresponding to the second height range.

[0076] Based on the ratio of the cumulative exit occupancy value corresponding to the first height range to the cumulative exit occupancy value corresponding to the second height range in the sum of the two, the actual exit throughput is allocated to the first height range and the second height range, forming the height range throughput corresponding to the first height range and the second height range respectively.

[0077] The relative height distribution of the material section at the inlet detection section is processed in the same way as the occupancy value formation method of the same height range, and the inlet side occupancy cumulative value corresponding to the first height range and the inlet side occupancy cumulative value corresponding to the second height range are formed respectively.

[0078] During the commissioning phase, a correspondence is established between the cumulative occupancy value at the inlet side and the weight of similar materials of known weight. Based on this correspondence, the cumulative occupancy value at the inlet side corresponding to the first height range is converted into a reference throughput for the first height range, and the cumulative occupancy value at the inlet side corresponding to the second height range is converted into a reference throughput for the second height range.

[0079] For a height range where material is covered, the throughput of that height range is compared with the reference throughput, and the ratio of the height range throughput to the reference throughput is used to determine the throughput of that height range.

[0080] In this embodiment, the preset pass requirement is determined in advance based on the allowable residual ratio. The allowable residual ratio represents the maximum proportion of the weight of the material that is allowed to not pass within the corresponding height range relative to the reference pass amount. The ratio obtained by subtracting the allowable residual ratio from one is used as the preset pass requirement.

[0081] When a matching result is formed within a corresponding height range and the degree of passage meets the preset passing requirements, the height range is determined as a passed height range; when a non-matching result is formed within a corresponding height range, or when a matching result is formed but the degree of passage does not meet the preset passing requirements, the height range is determined as a failed height range.

[0082] Step 4: Determine the weighing time period corresponding to the weighing position of the slope section through which the material section passes according to the actual displacement of the conveyor belt. Read the slope weighing value and the cross-sectional height data at the slope weighing position within the weighing time period. Determine the relative size of the occupancy of the first height range and the second height range within the weighing time period based on the cross-sectional height data, and allocate the slope weighing value according to the relative size of the occupancy. Include the allocated weighing value corresponding to the height range that has been passed into the effective conveying weight value, and include the allocated weighing value corresponding to the height range that has not been passed into the residual weight value. Read the distance from the inlet detection section to the weighing position on the slope along the conveying direction, as well as the positions of the material section at the foremost and last sampling sections along the conveying direction.

[0083] The starting time is determined by taking the sampling time corresponding to the first and last sampling sections, respectively. When the cumulative actual displacement of the conveyor belt after the starting time reaches the distance from the entrance detection section to the weighing position on the slope along the conveying direction, the start and end points of the corresponding weighing time period are determined respectively.

[0084] Within the corresponding weighing period, the weighing value of the slope segment and the cross-sectional height data at the weighing location of the slope segment are read according to the sampling cycle. The weighing value of the slope segment corresponds to the weight of the material passing through the weighing location of the slope segment within the corresponding sampling cycle, and is saved according to the correspondence between the sampling time and the cross-sectional height data at the weighing location of the slope segment.

[0085] Based on the bearing surface height reference corresponding to the weighing position of the slope section, the cross-sectional height data at the weighing position of the slope section at each collection time is converted into a relative height distribution, and the relative height data in the first height range and the second height range are read respectively according to the preset height division position.

[0086] For the first height range, the relative height value corresponding to each horizontal sampling position is read from the relative height distribution at the corresponding acquisition time, and it is determined whether the relative height value corresponding to each horizontal sampling position is within the height range corresponding to the first height range.

[0087] When the relative height value corresponding to the horizontal sampling position does not reach the lower boundary of the height range corresponding to the first height range, the relative height value corresponding to the horizontal sampling position will not participate in the formation of the first height range occupancy; when the relative height value corresponding to the horizontal sampling position reaches the height range requirement corresponding to the first height range, the height portion of the relative height value corresponding to the horizontal sampling position that belongs to the first height range will be extracted and used as the data for forming the first height range occupancy.

[0088] The height portion of the first height range corresponding to each lateral sampling position within the same acquisition time is accumulated to form the occupancy amount corresponding to the first height range at that acquisition time.

[0089] For the second height range, the same data processing method as for the first height range is used. The relative height values ​​corresponding to each lateral sampling position are read from the relative height distribution at the corresponding acquisition time, and it is determined whether the relative height values ​​corresponding to each lateral sampling position fall within the height range corresponding to the second height range.

[0090] When the relative height value corresponding to the horizontal sampling position does not reach the lower boundary of the height range corresponding to the second height range, the relative height value corresponding to the horizontal sampling position will not participate in the formation of the second height range occupancy; when the relative height value corresponding to the horizontal sampling position reaches the height range requirement corresponding to the second height range, the height portion of the relative height value corresponding to the horizontal sampling position that belongs to the second height range will be extracted and used as the data for forming the second height range occupancy.

[0091] The height portion of the second height range corresponding to each lateral sampling position within the same acquisition time is accumulated to form the occupancy amount corresponding to the second height range at that acquisition time.

[0092] Through the above processing, the occupancy corresponding to the first height range and the occupancy corresponding to the second height range are both derived from the cross-sectional height data at the weighing position of the slope section at the same collection time, and are formed using the same lateral sampling position arrangement relationship, so that the occupancy corresponding to the two height ranges can reflect the cross-sectional occupancy of different height ranges at the same collection time.

[0093] After the occupancy values ​​of the first and second altitude ranges are determined at the same acquisition time, the occupancy values ​​corresponding to the first and second altitude ranges are added together to form the total occupancy value corresponding to that acquisition time.

[0094] Based on the proportion of the occupancy in the total occupancy value corresponding to the first height range and the proportion of the occupancy in the total occupancy value corresponding to the second height range, the distribution ratio of the slope weighing value at the time of collection between the first height range and the second height range is determined.

[0095] The occupancy amount is used to represent the relative occupancy relationship between the first height range and the second height range in the cross section at the weighing position of the slope section, and is not used as a weight unit for accumulation; the slope section weighing value retains the dimension of weight and is divided according to the occupancy ratio of the corresponding height range, so that the sum of the allocated weighing value corresponding to the first height range and the allocated weighing value corresponding to the second height range is equal to the slope section weighing value at the time of collection.

[0096] Based on the occupancy ratio corresponding to the first height range, the slope weighing values ​​within the sampling period corresponding to the collection time are allocated to form the allocated weighing values ​​for the collection time corresponding to the first height range; based on the occupancy ratio corresponding to the second height range, the slope weighing values ​​within the same sampling period are allocated to form the allocated weighing values ​​for the collection time corresponding to the second height range.

[0097] Within the corresponding weighing time period, the weight values ​​allocated at the collection times corresponding to the first height range and the second height range are accumulated respectively to form the allocated weight values ​​corresponding to the first height range and the allocated weight values ​​corresponding to the second height range.

[0098] The weight distribution values ​​corresponding to the first and second height ranges after formation both maintain the same weight dimension as the slope section weight values, and respectively represent the weight distribution results corresponding to different height ranges.

[0099] During the weight assignment process, the previously formed height ranges that have been passed, height ranges that have not been passed, and the assigned weighing values ​​corresponding to the first height range and the second height range are read.

[0100] For assigned weighing values ​​that fall within the height range that have been passed, the corresponding assigned weighing values ​​will be accumulated and included in the effective transport weight value; for assigned weighing values ​​that fall outside the height range, the corresponding assigned weighing values ​​will be accumulated and included in the stagnant weight value.

[0101] Step 5: Generate the inlet feed adjustment amount and conveyor belt speed adjustment amount according to the height range corresponding to the retention weight value, and adjust the inlet feed and conveyor belt operation status accordingly; Specifically, after completing the aforementioned weight attribution process, the inlet feed adjustment amount and conveyor belt speed adjustment amount are determined based on the already formed residual weight value.

[0102] In this embodiment, the allocated weighing value included in the retention weight value is read and categorized and accumulated according to the height range corresponding to the allocated weighing value.

[0103] The system reads the height range judgment results corresponding to the height ranges that have been passed and those that have not been passed, and assigns weight to the allocated weighing values ​​based on the passing status corresponding to the first and second height ranges. For allocated weighing values ​​belonging to the height ranges that have not been passed, the weight is accumulated according to the corresponding height range and the time of acquisition to form the residual weight value corresponding to that height range; for allocated weighing values ​​belonging to the height ranges that have been passed, they do not participate in the formation of the residual weight value, and are accumulated according to the corresponding height range to form the effective transport weight value.

[0104] When there is no corresponding assigned weighing value in the first height range or the second height range, the residual weight value of the corresponding height range is set to zero, so that the first height range and the second height range both form corresponding residual weight values.

[0105] The weight values ​​for the first and second height ranges are both derived from the aforementioned allocated weighing values ​​and maintain the same weight dimensions as the slope section weighing values. Specifically, the weight value for the first height range is formed by the allocated weighing value corresponding to the condition when the first height range is determined to be a height range not yet traversed, and the weight value for the second height range is formed by the allocated weighing value corresponding to the condition when the second height range is determined to be a height range not yet traversed.

[0106] After determining the retention weight values ​​for the first and second height ranges, the retention weight values ​​for the two height ranges are accumulated to form the total retention weight value.

[0107] In this embodiment, the preset retention weight reference value is predetermined based on the upper limit of the retention weight allowed by the conveyor in the state of continuous conveying, and is used as the weight benchmark for determining the degree of operation adjustment.

[0108] When the total value of the retained weight is greater than zero, the preset retained weight reference value is read and compared with the preset retained weight reference value; when the total value of the retained weight is less than the preset retained weight reference value, the ratio of the total value of the retained weight to the preset retained weight reference value is used as the degree of operation adjustment; when the total value of the retained weight reaches or exceeds the preset retained weight reference value, the degree of operation adjustment is recorded as one.

[0109] Calculate the ratio of the weight of the stranded items to the total weight of the stranded items corresponding to the first height range and the ratio of the weight of the stranded items to the total weight of the stranded items corresponding to the second height range, respectively, to form the first stranded percentage and the second stranded percentage.

[0110] In this embodiment, the allowable reduction of the conveyor belt speed and the allowable reduction of the inlet feed rate are determined during the equipment commissioning phase based on the minimum operating speed and minimum feed rate required for the conveyor to maintain continuous conveying, and are respectively used as the lower limits for conveyor belt speed adjustment and inlet feed rate adjustment.

[0111] Read the current conveyor belt running speed and the allowable reduction speed of the conveyor belt, and form the range of conveyor belt speed reduction based on the difference between the two; multiply the reduction amount corresponding to the range of conveyor belt speed reduction by the degree of operation adjustment and the first stagnation ratio to form the conveyor belt speed adjustment amount.

[0112] Read the current inlet feed rate and the allowable inlet feed rate, and form the inlet feed rate reduction range based on the difference between the two; multiply the reduction range corresponding to the inlet feed rate reduction by the operation adjustment degree and the second retention ratio to form the inlet feed adjustment amount.

[0113] The current conveyor belt speed is reduced by the conveyor belt speed adjustment amount to obtain the adjusted conveyor belt speed; the current inlet feed rate is reduced by the inlet feed adjustment amount to obtain the adjusted inlet feed rate, and the conveyor operation is controlled according to the adjusted conveyor belt speed and inlet feed rate.

[0114] When the total weight of the retained material is zero, no conveyor belt speed adjustment or inlet feed adjustment is generated, and the current conveyor belt running speed and inlet feed rate are maintained.
