Description

TECHNICAL FIELD

[0001] The present application belongs to the field of textile automatic control technology, in particular to a tray type automatic cone winding equipment empty tube tray feeding supply and distribution system. BACKGROUND

[0002] In the production process of the tray type automatic cone winding equipment, the feeding supply and distribution of the empty tube tray is crucial, which directly affects the efficiency and stability of the entire production line.

[0003] The existing tray type automatic cone winding equipment empty tube tray feeding supply and distribution system lacks effective analysis and judgment mechanism for the stability of the tray passing interval time during operation. In actual production, due to the influence of factors such as equipment running state and material supply, the tray passing interval time on A road and B road often fluctuates, making it difficult to reasonably plan the subsequent supply and distribution operation, easily causing system running disorder and affecting production efficiency. Secondly, the traditional tray type automatic cone winding equipment empty tube tray feeding supply and distribution system lacks a scientific matching degree analysis method when supplying and distributing A road and B road. The interval time stability of the trays on different routes is different, and if the matching degree of AB road distribution time cannot be reasonably determined according to the actual situation, the closing time and release time of the anti-blocking device cannot be reasonably set, and in actual production, as the equipment running time increases, the interval time of the trays may continuously shorten, increasing the possibility of collision between adjacent trays, and if the closing time of B road cannot be adjusted in time, the trays of B road may collide with the trays of A road at the intersection, or the trays of B road cannot be supplied in time, affecting the continuity of the entire production process.

[0004] Therefore, the present application provides a tray type automatic cone winding equipment empty tube tray feeding supply and distribution system. SUMMARY

[0005] In order to make up for the shortcomings of the prior art and solve at least one technical problem raised in the background art.

[0006] The technical solution adopted by the present application to solve its technical problems is: A tray type automatic cone winding equipment empty tube tray feeding supply and distribution system, comprising the following modules: Time interval stability analysis module: set the simulation running period, respectively analyze the stability of the passing interval time of the trays on A road and B road in the divided simulation running period, and judge whether the interval time of the trays on A road and B road is stable; Time interval matching analysis module: according to the stability of the interval time of the trays on A road and B road, analyze the matching degree of supply and distribution, and determine the matching degree of AB road distribution time; Risk impact assessment module: if the matching degree is high, the change trend of the tray interval time on the A road and the B road is obtained respectively, the adjacent tray collision risk on the A road and the B road is analyzed respectively, the AB road intersection collision prediction risk is analyzed, and the coupling correlation analysis is performed to assess the risk correlation impact degree; Shunt timing adjustment module: if the risk correlation impact degree is large, the B road tray operation is adjusted, the B road closing time adjustment amount is obtained, and the timer is adjusted according to the B road closing time adjustment amount.

[0007] Preferably, whether the tray interval time on the A road and the B road is stable is judged, and the process is as follows: In the simulation running period, the simulation running time points of each tray passing through photoelectric 1# detection on the A road and the B road are recorded respectively, the time length between the simulation running time points of adjacent trays passing through photoelectric 1# detection on the A road and the time length between the simulation running time points of adjacent trays passing through photoelectric 2# detection on the B road are obtained, the ratio of the total time length of the simulation running period is obtained, and the A tray single-pass time interval ratio and the B tray single-pass time interval ratio are obtained; The A tray single-pass time interval ratio is calculated by mean value and standard deviation respectively, and the A tray single-pass time interval mean value and the A tray single-pass time interval standard deviation are output; The B tray single-pass time interval ratio is calculated by mean value and standard deviation respectively, and the B tray single-pass time interval mean value and the B tray single-pass time interval standard deviation are output; The A tray single-pass time interval mean value and the A tray single-pass time interval standard deviation, and the B tray single-pass time interval mean value and the B tray single-pass time interval standard deviation are input into the coefficient of variation formula respectively, and the A tray time interval stable value and the B tray time interval stable value are output; If the A tray time interval stable value is less than or equal to the A tray time interval stable threshold value, the A tray passing interval stable signal is displayed; If the B tray time interval stable value is less than or equal to the B tray time interval stable threshold value, the B tray passing interval stable signal is displayed.

[0008] Preferably, according to the tray interval time stability on the A road and the B road, the supply shunt matching degree analysis is performed, and the process is as follows: If the A tray passing interval fluctuation signal is displayed, all A tray single-pass time interval ratios are compared in size, and the minimum A tray single-pass time interval ratio is selected as the A tray interval representative value; If the A tray passing interval stable signal is displayed, the A tray single-pass time interval mean value is selected as the A tray interval representative value; If the B tray passing interval fluctuation signal is displayed, all B tray single-pass time interval ratios are compared in size, and the minimum B tray single-pass time interval ratio is selected as the B tray interval representative value; If the display shows a stable signal for the B tray through the time interval, then the average single-pass time interval of the B tray will be used as the representative value of the B tray interval time.

[0009] Preferably, the matching degree of the A and B route splitting time is determined as follows: The difference between the representative value of the A-channel interruption time and the representative value of the B-channel interruption time is obtained. If the representative value of the interruption time is less than the current B-channel closing time, it is displayed as a high AB-channel shunt matching signal.

[0010] Preferably, the trend of pallet interval time changes on routes A and B is obtained separately, and the process is as follows: Extract all single-pass interval ratios of tray A in the simulated operation cycle, and substitute them into a two-dimensional coordinate system according to the obtained time series. With the X-axis as the time sorting and the Y-axis as the single-pass interval ratio of tray A, construct the tray interval change curve of route A. Extract all single-pass interval ratios of B trays within the simulated operating cycle, and substitute them into a two-dimensional coordinate system according to the obtained time series. With the X-axis as the time sorting and the Y-axis as the single-pass interval ratio of B trays, construct the tray interval variation curve of B route.

[0011] Preferably, the risk of collision between adjacent pallets on route A is analyzed, and the process is as follows: On the time interval variation curve of tray A, adjacent coordinate points are combined to obtain multiple adjacent coordinate analysis groups; Input the adjacent coordinate points in each adjacent coordinate analysis group into the slope calculation formula, and output the slope of unit A at time interval; Extract the slopes of all A-interval units that are negative and whose time order is continuous on the A-interval change curve, and truncate them to obtain the A-interval continuously shortening curve. Obtain the proportion of the length of the A-path interval continuously shortening curve to the length of the A-path tray interval change curve, and get the A-path continuously shortening length ratio; The A-path shortening duration value is obtained by summing the A-path shortening length ratio corresponding to each A-path time interval shortening curve. Extract the slope of the minimum A-interval unit on each curve of continuous shortening of A-interval, and calculate the average value of the summation to output the average value of shortening of A-interval. The duration of shortening of route A is summed with the mean of shortening of the interval of route A, and the interval analysis value of tray A is output. If the time interval analysis value of tray A is less than the time interval analysis threshold of tray A, it will be displayed as a signal of high collision risk level of road A.

[0012] Preferably, the risk of collision between adjacent pallets on route B is analyzed, and the process is as follows: On the time interval variation curve of tray B, adjacent coordinate points are combined to obtain multiple adjacent coordinate analysis groups; Input the adjacent coordinate points in each adjacent coordinate analysis group into the slope calculation formula, and output the slope of the B time interval unit. Extract the slopes of all A time interval units that are negative and whose time intervals are consecutive on the B-path tray interval change curve, and then truncate them to obtain the B-path interval continuously shortening curve. Obtain the proportion of the length of the continuously shortening interval curve of route B to the length of the tray interval change curve of route A, and get the length ratio of the continuously shortening interval of route B; The summation of the B-path shortening length ratio corresponding to each B-path time interval shortening curve is used to output the B-path shortening duration value. Extract the slope of the minimum B-interval unit on each curve of continuous shortening of B-interval, and calculate the average value of the summation to output the average value of shortening of B-interval. The B-path shortening duration value is summed with the B-path interval shortening mean value to output the B-path collision risk value. If the B-path interval analysis value is less than the B-path interval analysis threshold, it is displayed as a high signal of B-path collision risk.

[0013] Preferably, the risk of collision at the intersection of roads A and B is analyzed and predicted as follows: Extract the time periods within the simulated operating cycle of each curve where the interval of A continuously shortens and the time periods within the simulated operating cycle of each curve where the interval of B continuously shortens, and use them as the interval periods where the interval of A continuously shortens and the interval of B continuously shortens. By combining any A-path time interval continuously shortening curve and B-path time interval continuously shortening curve, multiple AB-path time interval continuously shortening analysis groups are obtained; The overlapping comparison between the continuously shortening time interval A and the continuously shortening time interval B is performed to obtain the duration of the overlapping part of the time interval A and the continuously shortening time interval B. The ratio of this overlap to the duration of the simulation cycle is calculated, and the overlap value of the unit time interval is output. Sum the overlap values ​​of all unit time periods and output the continuous shortening overlap value of the AB time interval.

[0014] Preferably, the collision risks of adjacent pallets on routes A and B, as well as the predicted collision risks at the intersection of routes A and B, are coupled and correlated to assess the degree of risk correlation. The process is as follows: Extract the AB path time interval continuously shortening analysis group that shows a high risk level of AB path intersection collision prediction, and sum the absolute values ​​of the A path time interval shortening mean corresponding to the A path time interval continuously shortening curve and the B path time interval shortening mean corresponding to the B path time interval continuously shortening curve within the AB path time interval continuously shortening analysis group, and output the AB path time interval shortening mean value. Extract the analysis group of AB road time intervals that show a high risk of AB road intersection collision prediction, obtain the corresponding AB time intervals continuous shortening overlap value, and calculate the coupling correlation influence value by combining it with the average value of AB road time interval shortening using the Pearson correlation coefficient formula; If the coupling correlation impact value is greater than the coupling correlation impact threshold, it is displayed as a signal of close risk correlation impact.

[0015] Preferably, for the B-channel tray operation, the process of obtaining the B-channel shutdown time adjustment amount and adjusting the timer is as follows: The product of the difference in the interval time and the coupling-related impact value, and then the sum of the product and the difference in the interval time, yields the adjustment amount for the closing time of route B. The difference between the current B-path closing time and the adjusted B-path closing time is calculated, and the adjusted B-path closing time is output.

[0016] The beneficial effects of this invention are as follows: 1. This invention sets a simulated operation cycle and performs stability analysis on the passage interval time of pallets on routes A and B within the divided simulated operation period to determine whether the pallet interval time on routes A and B is stable. Based on the stability of the pallet interval time on routes A and B, representative values ​​of the interval time of pallets A and B are obtained respectively, and a supply diversion matching degree analysis is performed to determine the matching degree of the diversion time of routes A and B. Determining the matching degree helps to reasonably set the closing time and release time of the anti-blocking device. Based on the matching degree, it ensures that the pallets can pass through the intersection smoothly. Moreover, determining the matching degree of the diversion time of routes A and B enables routes A and B to supply empty pipe pallets to the CBF channel at a reasonable time rhythm. 2. If the matching degree is high, the present invention obtains the changing trend of the pallet interval time on routes A and B respectively, analyzes the collision risk of adjacent pallets on routes A and B respectively, and predicts the collision risk at the intersection of routes A and B, and performs coupling correlation analysis to assess the degree of risk correlation impact. If the degree of risk correlation impact is large, the operation of pallets on route B is adjusted, the adjustment amount of the closing time of route B is obtained, and the timer is adjusted according to the adjustment amount of the closing time of route B. After adjusting the closing time of route B, route B can obtain a stable release window, so that empty tube pallets can be supplied from route B to the CBF direction in a timely manner, cooperating with the empty tube pallets supplied by route A. Moreover, after the adjustment, routes A and B can operate at a more reasonable rhythm, avoiding the situation where the release of one side is blocked and affects the other side, making the operation of the entire diversion system smoother and improving the efficiency of empty tube pallet loading and supply.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0020] Please see Figs. 1-3 As shown, the tray-type automatic winding equipment includes routes A and B. Because empty tube trays continuously circulate between routes A and B during the spinning of low-count yarns, when the CBF (Cyclone Fiber) empty tube removal channel finishes processing, the A-rod running channel doesn't replenish the empty tube trays in time. The empty tube trays continue circulating on the B-rod, causing the CBF to stop and wait, affecting the CBF's empty tube finding and yarn supply efficiency. Therefore, after modification, the original spindles 1-36 were diverted from the middle of the A-rod channel to the B-rod channel. By adjusting the B-rod conveyor belt motor's running direction (motor reverse), the original B-rod circulating channel also supplies empty tube trays towards the CBF. The original spindles 37-72 continue to be supplied from route A to the CBF channel. A supply diversion system was added at the intersection of routes A and B with the CBF channel. The basic working principle is: using Mitsubishi PLC / amplifier board, infrared photoelectric sensors, magnetic proximity switches, solenoid valves, and cylinders for logic programming control. Route A is given priority; when photoelectric sensor #1 detects a tray passing by, route B is closed for a certain period. The closing time for route B can be 4.5 seconds. Photoelectric sensor #1 resets the closing time for route B each time it detects a pallet. If no pallet passes through route A within the closing time, route A will be closed, and route B will be allowed to pass. When photoelectric sensor #2 detects that a pallet on route B has not moved for a certain period (2.5 seconds), the timer will be set to allow route B to pass for 10 seconds. Simultaneously, the closing time for route A is the same as the opening time for route B. Furthermore, the anti-blocking device for route B will close for a certain period (4.5 seconds) to prevent excessive pallet movement and resulting congestion. When photoelectric sensor #1 detects that a pallet has not moved for a certain period (3 seconds), route A will be allowed to pass first, and route B will be closed. When photoelectric sensors #4 and #5 at the junction detect that a pallet has not moved for a certain period (1.5 seconds), both routes A and B will be closed simultaneously to prevent congestion. This embodiment of the invention provides a pallet-type automatic winding equipment empty pipe pallet feeding and distribution system, which includes the following modules: Time Interval Stability Analysis Module: Set the simulation operation cycle and perform stability analysis on the transit interval time of pallets on routes A and B within the divided simulation operation period to determine whether the pallet interval time on routes A and B is stable. It should be noted that the simulated operation cycle refers to the period set for testing the empty tube pallet feeding and diversion strategy of the pallet-type automatic winding equipment. Within this set simulated operation cycle, the situation of empty tube pallet feeding and diversion in the textile workshop is reproduced. The purpose is to observe the operation data of the empty tube pallets passing through the A and B routes, such as the interval time between adjacent pallets passing through the A and B routes. In some embodiments, a stability analysis is performed on the pallet passing interval time on route A to determine whether the pallet passing interval time on route A is stable. The process is as follows: During the simulated operation cycle, the simulated operation time point when each pallet on Road A passes through photoelectric sensor #1 is recorded, and the time between the simulated operation time points when adjacent pallets on Road A pass through photoelectric sensor #1 is obtained, along with the ratio of the time between these simulated operation time points to the total simulated operation time, thus obtaining the single-pass time interval ratio of pallet A. Calculate the mean and standard deviation of the single-pass interval for all A-pallets, and output the mean and standard deviation of the single-pass interval for A-pallets. Input the mean and standard deviation of the single-pass interval of tray A into the coefficient of variation formula to obtain the stable value of the time interval of tray A. If the stable value of the time interval of tray A is greater than the stable threshold of the time interval of tray A, it means that the interval between adjacent trays passing through photoelectric sensor #1 on road A is relatively unstable, which is displayed as the time interval fluctuation signal of tray A. If the stable time interval value of tray A is less than or equal to the stable time interval threshold of tray A, it means that the interval time when adjacent trays pass through photoelectric sensor #1 on road A is relatively stable, and it is displayed as a stable time interval signal of tray A. A stability analysis was performed on the pallet passing intervals on route B to determine whether the pallet passing intervals on route B were stable. The process is as follows: During the simulated operation cycle, the simulated operation time point when each pallet on route B passes through photoelectric sensor #2 is recorded, and the time between the simulated operation time points when adjacent pallets on route B pass through photoelectric sensor #2 is obtained, along with the ratio of the time between these times to the total simulated operation time, to obtain the single-pass time interval ratio of pallet B. Calculate the mean and standard deviation of the single-pass interval for all B trays, and output the mean and standard deviation of the single-pass interval for B trays. Input the mean and standard deviation of the single-pass interval of tray B into the coefficient of variation formula to obtain the stable value of the time interval of tray B. If the stable value of the time interval of tray B is greater than the stable threshold of the time interval of tray B, it means that the interval time when adjacent trays pass through photoelectric sensor #1 on road A is relatively unstable, which is displayed as the time interval fluctuation signal of tray B. If the stable time interval value of tray B is less than or equal to the stable time interval threshold of tray B, it means that the interval time when adjacent trays pass through photoelectric sensor #1 on road A is relatively stable, and it is displayed as a stable time interval signal of tray B. The purpose of determining whether the pallet interval time on routes A and B is stable is that, from the perspective of pallet supply efficiency, stable delivery of empty tube pallets from routes A and B to the CBF channel helps avoid the situation where the CBF waits for empty tube pallets due to irregular pallet supply, thereby improving the efficiency of empty tube finding and yarn supply in the CBF. From the perspective of preventing congestion, a stable pallet interval means that the flow of pallets on routes A and B, as well as at intersections, is more orderly. This reduces the accumulation and collision of pallets caused by uneven intervals during operation, lowering the risk of congestion. As a result, the closing and release times of the anti-congestion device can be set reasonably to ensure that pallets can pass through intersections smoothly and avoid affecting the entire material supply process due to congestion. For unstable pallet intervals, by analyzing their fluctuations, potential congestion points can be predicted in advance, and corresponding measures can be taken, such as adjusting the time parameters in the diversion strategy, to prevent congestion and ensure the normal operation of the pallet-type automatic winding equipment.

[0021] Time Interval Matching Analysis Module: Based on the stability of the pallet interval time on routes A and B, representative values ​​of the A pallet interval time and B pallet interval time are obtained respectively, and supply diversion matching degree analysis is performed to determine the matching degree of the A and B routes in terms of diversion time; In some embodiments, the value of the A-interval time is obtained as follows: If the signal is a fluctuation in the time interval of tray A, then the single-pass time interval ratios of all tray A are compared, and the smallest single-pass time interval ratio of tray A is selected as the representative value of tray A interval time. If the display shows a stable signal for the passage of tray A, then the average single passage interval of tray A will be used as the representative value of the interval time of tray A. The B-side interval time representative value is obtained as follows: the A-side interval time representative value reflects the time interval characteristics of pallet supply on route A, and the B-side interval time representative value reflects the time interval characteristics of pallet supply on route B. The difference in interval time represents the degree of asynchrony between routes A and B in the time interval when supplying empty pipe pallets. If the difference in interval time is positive and large, it indicates that the average time interval of pallet supply on route A is longer than that on route B, that is, the supply rhythm of route A is relatively slower; if the difference is negative and large, it indicates that the supply rhythm of route B is relatively slower. This rhythm difference may lead to poor coordination between the two routes when supplying pallets to the CBF channel, affecting the overall supply efficiency. If the signal is a fluctuation in the time interval of B tray, then the single-pass time interval ratios of all B trays are compared, and the smallest single-pass time interval ratio of B tray is selected as the representative value of B tray interval time. If the display shows a stable signal for the B tray through the time interval, then the average single-pass time interval of the B tray will be used as the representative value of the B tray interval time. The difference between the representative value of the A-interval time and the representative value of the B-interval time is obtained as the representative difference of the interval time. It is understandable that the difference in the interval time represents the following meaning: If the difference between the delay time and the current B-path closing time is greater than or equal to the current B-path closing time, it means that the A-path interval is much larger than the B-path interval. The A-path priority logic conflicts with the B-path release requirement, and the B-path is prone to backlog, which is displayed as a low A / B path splitting matching signal. If the difference between the interval and the current B-path closing time is less than the current B-path closing time, it indicates that the A-path interval and the B-path interval are well matched, and the A-path priority logic can take into account the B-path release, which is displayed as a signal of high A / B path splitting matching. The purpose of determining the matching degree of the A and B route splitting time is to ensure the stable and efficient operation of the tray-type automatic winding equipment. Specifically, from the perspective of supply efficiency, in the original operation of the tray-type automatic winding equipment, there is a situation where the CBF stops and waits because the empty tube trays of the A route are not replenished in time, while the trays are still circulating in the B route. This seriously affects the CBF empty tube finding and yarn supply efficiency. Determining the matching degree of the A and B route splitting time can enable the A and B routes to supply empty tube trays to the CBF channel at a reasonable time rhythm. From the perspective of preventing congestion, stable pallet interval time and high diversion matching degree mean that the flow of pallets in route A, route B and the intersection is more orderly. When the diversion time matching degree of route A and B is high, the time interval between the arrival of pallets from the two routes at the intersection is reasonable, and there will be no situation where a large number of pallets arrive at the intersection at a certain time. This reduces the accumulation of pallets during operation and reduces the risk of congestion. Therefore, determining the matching degree helps to reasonably set the closing time and release time of the anti-congestion device, and ensures that pallets can pass through the intersection smoothly according to the matching degree. From a production management perspective, determining the matching degree of the A and B route splitting time provides detailed data support, which helps production managers understand the operating status of the pallet-type automatic winding equipment. Based on the matching degree data, managers can evaluate the effectiveness of the existing splitting strategy, decide whether further optimization and improvement of the equipment is needed, and rationally allocate resources for the A and B routes, such as adjusting the number of spindles. The specific solution in this embodiment is as follows: A simulated operating cycle is set, and the stability of the passage interval time of pallets on routes A and B within the divided simulated operating segments is analyzed to determine whether the pallet interval time on routes A and B is stable. Based on the stability of the pallet interval time on routes A and B, representative values ​​of the interval time for routes A and B are obtained respectively, and a supply diversion matching degree analysis is performed to determine the matching degree of the diversion time of routes A and B. Determining the matching degree helps to reasonably set the closing and release times of the anti-blocking device. Based on the matching degree, it is ensured that the pallets can pass smoothly through the intersection. Moreover, determining the matching degree of the diversion time of routes A and B enables routes A and B to supply empty pipe pallets to the CBF channel according to a reasonable time rhythm. Example 2

[0022] Please see Figs. 1-3 As shown in the embodiment of the present invention, an empty pipe pallet feeding and distribution system for an automatic winding equipment further includes the following modules: Risk Impact Assessment Module: If the matching degree is high, the changing trends of pallet interval time on routes A and B are obtained respectively, the collision risk of adjacent pallets on routes A and B is analyzed, and the collision prediction risk at the intersection of routes A and B is performed. Coupled correlation analysis is conducted to assess the degree of risk correlation impact. In some embodiments, the changing trends of pallet interval times on routes A and B are obtained respectively, as follows: Extract all single-pass interval ratios of tray A in the simulated operation cycle, and substitute them into a two-dimensional coordinate system according to the obtained time series. With the X-axis as the time sorting and the Y-axis as the single-pass interval ratio of tray A, construct the tray interval change curve of route A. Similarly, extract all single-pass interval ratios of B trays within the simulated operation cycle, and substitute them into the two-dimensional coordinate system according to the obtained time series. With the X-axis as the time sorting and the Y-axis as the single-pass interval ratio of B trays, construct the tray interval change curve of B route. The process of analyzing the collision risk of adjacent pallets on routes A and B is as follows: On the time interval variation curve of tray A, adjacent coordinate points are combined to obtain multiple adjacent coordinate analysis groups; Input the adjacent coordinate points in each adjacent coordinate analysis group into the slope calculation formula, and output the slope of unit A at time interval; Extract the slopes of all A-interval units that are negative and whose time order is continuous on the A-interval change curve, and truncate them to obtain the A-interval continuously shortening curve. Obtain the proportion of the length of the A-path interval continuously shortening curve to the length of the A-path tray interval change curve, and get the A-path continuously shortening length ratio; The A-path shortening duration value is obtained by summing the A-path shortening length ratio corresponding to each A-path time interval shortening curve. Extract the slope of the minimum A-interval unit on each curve of continuous shortening of A-interval, and calculate the average value of the summation to output the average value of shortening of A-interval. The duration of shortening of route A is summed with the mean of shortening of the interval of route A, and the interval analysis value of tray A is output. It is understandable that the meaning of the A-pallet interval analysis value is: it combines two factors, namely the coverage of the continuous shortening of pallet interval time on A-road and the severity of the shortening of interval time. On the one hand, the A-road shortening duration value reflects the coverage of the continuous shortening of pallet interval time on A-road throughout the entire operating cycle. On the other hand, the A-road interval shortening average value reflects the severe shortening among all interval shortening curves. If the time interval analysis value of pallet A is less than the time interval analysis threshold of pallet A, it indicates that the time interval between adjacent pallets on road A has been continuously shortened for a long time, and the risk of collision between adjacent pallets is relatively high, which is displayed as a signal of high collision risk on road A. If the time interval analysis value of pallet A is greater than the time interval analysis threshold of pallet A, it indicates that the time interval between adjacent pallets on road A is shortened, the risk of collision between adjacent pallets is small, and it is displayed as a signal of low collision risk on road A. Similarly, on the time interval change curve of tray B, adjacent coordinate points are combined to obtain multiple adjacent coordinate analysis groups; Input the adjacent coordinate points in each adjacent coordinate analysis group into the slope calculation formula, and output the slope of the B time interval unit. Extract the slopes of all A time interval units that are negative and whose time intervals are consecutive on the B-path tray interval change curve, and then truncate them to obtain the B-path interval continuously shortening curve. Obtain the proportion of the length of the continuously shortening interval curve of route B to the length of the tray interval change curve of route A, and get the length ratio of the continuously shortening interval of route B; The summation of the B-path shortening length ratio corresponding to each B-path time interval shortening curve is used to output the B-path shortening duration value. Extract the slope of the minimum B-interval unit on each curve of continuous shortening of B-interval, and calculate the average value of the summation to output the average value of shortening of B-interval. The collision risk value of tray B is obtained by summing the duration of shortening of path B with the mean of shortening of path B interval. It is understandable that the meaning of the collision risk value of pallet B is: it combines two factors, namely the coverage of the continuous shortening of pallet interval time on route B and the severity of the shortening of interval time. On the one hand, the duration of shortening on route B reflects the coverage of the continuous shortening of pallet interval time on route B throughout the entire operating cycle. On the other hand, the average shortening of interval time on route B reflects the severe shortening situation among all the continuous shortening curves of interval time. If the B pallet time interval analysis value is less than the B pallet time interval analysis threshold, it indicates that the time interval between adjacent pallets on B road has been continuously shortened for a long time, and the collision risk between adjacent pallets is relatively high, which shows a high collision risk signal on B road. If the B pallet time interval analysis value is greater than the B pallet time interval analysis threshold, it indicates that the time interval between adjacent pallets on B road is shortened, the risk of collision between adjacent pallets is small, and it is displayed as a signal of low collision risk on B road. The process for analyzing and predicting the collision risk at the intersection of roads A and B is as follows: Extract the time periods within the simulated operating cycle of each curve where the interval of A continuously shortens and the time periods within the simulated operating cycle of each curve where the interval of B continuously shortens, and use them as the interval periods where the interval of A continuously shortens and the interval of B continuously shortens. By combining any A-path time interval continuously shortening curve and B-path time interval continuously shortening curve, multiple AB-path time interval continuously shortening analysis groups are obtained; The overlapping comparison between the continuously shortening time interval A and the continuously shortening time interval B is performed to obtain the duration of the overlapping part of the time interval A and the continuously shortening time interval B. The ratio of this overlap to the duration of the simulation cycle is calculated, and the overlap value of the unit time interval is output. Sum the overlap values ​​of all unit time periods and output the continuous shortening overlap value of the AB time interval; For example, if there are 3 and 4 continuously shortening time interval curves for path A and path B respectively in the simulation period, the continuously shortening time interval curves for path A include the continuously shortening time interval curves for paths A1, A2, and A3, and the continuously shortening time interval curves for path B include the continuously shortening time interval curves for paths B1, B2, B3, and B4. If the time interval of the A1 channel continuously shortening curve overlaps with the time interval of the B1 channel (or the time intervals of the B2, B3, and B4 channels continuously shortening curves) within the simulation cycle, then the duration of the overlapping period between the A and B time intervals is obtained, and the ratio is calculated with the duration corresponding to the simulation cycle, and the overlap value of the unit time interval is output. If the time interval of the A2 channel continuously shortening curve overlaps with the time interval of the B1 channel (or the time intervals of the B2, B3, and B4 channels continuously shortening curves) within the simulation cycle, then the duration of the overlapping period between the A and B time intervals is obtained, and the ratio is calculated with the duration corresponding to the simulation cycle, and the overlap value of the unit time interval is output. If the time interval of the A3 channel continuously shortening curve overlaps with the time interval of the B1 channel (or the time intervals of the B2, B3, and B4 channels continuously shortening curves) within the same simulation cycle, then the duration of the overlapping period between the A and B time intervals is obtained, and the ratio is calculated with the duration corresponding to the simulation cycle, and the overlap value of the unit time interval is output. If the AB time interval continues to shorten and the overlap value is greater than or equal to the AB time interval continues to shorten and the overlap threshold, it indicates that the AB intersection collision prediction risk is relatively high, and it is displayed as a high AB intersection collision prediction risk signal. If the AB time interval continues to shorten and the overlap value is less than the AB time interval continues to shorten and the overlap threshold, it indicates that the AB intersection collision prediction risk is relatively small, and it is displayed as a low AB intersection collision prediction risk signal. The collision risks of adjacent pallets on routes A and B, as well as the predicted collision risks at the intersection of routes A and B, are coupled and correlated to assess the degree of risk correlation. The process is as follows: Extract the AB path time interval continuously shortening analysis group that shows a high risk level of AB path intersection collision prediction, and sum the absolute values ​​of the A path time interval shortening mean corresponding to the A path time interval continuously shortening curve and the B path time interval shortening mean corresponding to the B path time interval continuously shortening curve within the AB path time interval continuously shortening analysis group, and output the AB path time interval shortening mean value. Extract the analysis group of AB road time intervals that show a high risk of AB road intersection collision prediction, obtain the corresponding AB time intervals continuous shortening overlap value, and calculate the coupling correlation influence value by combining it with the average value of AB road time interval shortening using the Pearson correlation coefficient formula; It is understandable that the meaning of the coupling correlation impact value is: to measure the degree of linear correlation between the continuous shortening overlap value of the A and B time intervals (degree of time overlap) and the average value of the A and B time interval shortening (degree of drastic shortening of the interval time). Specifically, if the correlation is relatively strong, it means that the period of the A risk almost overlaps with the period of the B risk (e.g., the A risk lasts for 10 to 25 minutes, and the B risk lasts for 12 to 27 minutes, with an overlap of 12 to 25 minutes). The two risks are highly bound in time, and the converging risks are naturally concentrated in this period. If the correlation is relatively weak; If the coupling correlation impact value is greater than the coupling correlation impact threshold, it indicates that the period of continuous risk of route A and the period of continuous risk of route B overlap significantly, the concentration of converged risks is high, which shows a signal that the risk correlation impact is not close. If the coupling correlation impact value is less than or equal to the coupling correlation impact threshold, it indicates that the period of risk duration of route A and the period of risk duration of route B overlap significantly, and the concentration of converged risks is high, which shows a close risk correlation impact signal. The purpose of assessing the degree of risk correlation impact is to: by calculating the coupling correlation impact value, we can identify potential correlation risks between the operating states of route A and route B in advance, and also optimize the empty tube pallet feeding and supply diversion system of the pallet-type automatic winding equipment; From the perspective of operational efficiency, one of the important reasons why the efficiency of empty tube finding and yarn supply in pallet-type automatic winding equipment is affected is that the empty tube pallet is not replenished in time in the A-line running channel, causing the CBF to stop and wait. By evaluating the coupling and correlation impact value, the coordination between the A-line and B-line in pallet supply can be improved. It can also reflect the risk of pallet blockage at the intersection of the A and B-line, and timely measures can be taken to prevent blockage and avoid the efficiency of the entire feeding and supply system from decreasing due to blockage. The timing adjustment module for traffic diversion: If the impact of risk association is significant, adjustments will be made to the operation of the B-path tray, the adjustment amount of the B-path shutdown time will be obtained, and the timer will be adjusted according to the adjustment amount of the B-path shutdown time. In some embodiments, for B-path tray operation, the process of obtaining the B-path shutdown time adjustment amount and adjusting the timer is as follows: The product of the difference in the interval time and the coupling-related impact value, and then the sum of the product and the difference in the interval time, yields the adjustment amount for the closing time of route B. The difference between the current B-path shutdown time and the B-path shutdown time adjustment is calculated, and the adjusted B-path shutdown time is output. The specific solution in this embodiment is as follows: If the matching degree is high, the changing trend of the pallet interval time on routes A and B is obtained respectively. The collision risk of adjacent pallets on routes A and B, as well as the predicted collision risk of the intersection of routes A and B, are analyzed separately. Coupled correlation analysis is performed to assess the degree of risk correlation impact. If the degree of risk correlation impact is large, the operation of the pallets on route B is adjusted. The adjustment amount of the closing time of route B is obtained, and the timer is adjusted according to the adjustment amount of the closing time of route B. After adjusting the closing time of route B, route B can obtain a stable release window, so that empty tube pallets can be supplied from route B to the CBF direction in a timely manner, cooperating with the empty tube pallets supplied by route A. Moreover, after the adjustment, routes A and B can operate at a more reasonable rhythm, avoiding the situation where the release of one side is blocked and affects the other side, making the operation of the entire diversion system smoother and improving the efficiency of empty tube pallet loading and supply.
