Description

Technical Field

[0001] The present invention relates to the technical field of cable take-up and arrangement machine, and in particular to a cable take-up and arrangement machine control system and a control method. Background Art

[0002] With the rapid development of modern society, cables are an important part of infrastructure such as power, communication, and data transmission, and their demand is increasing. In many fields such as power transmission, communication network construction, household appliances, and industrial manufacturing, the arrangement, storage, and transportation of cables have become an important task. The emergence of cable take-up machines has greatly met this market demand and improved the efficiency and convenience of cable management.

[0003] If the cable is not neatly arranged during the process of using the cable take-up machine to take up and arrange the cable, it may cause the cable to be entangled, knotted or damaged in subsequent use, thereby affecting the performance and life of the product. At the same time, the uneven arrangement of the cable will lead to the need for rework or re-arranging the cable in the subsequent process, thereby reducing production efficiency. However, at present, when using the cable take-up machine to take up and release the cable, most of them lack the monitoring process of the neatness of the discharge cable, which leads to the inability to timely understand the irregularity of the discharge cable process and make timely adjustments;

[0004] In view of this, we propose a cable take-up and arrangement control system and control method for a cable take-up machine. Summary of the invention

If the speed judgment value is greater than the speed judgment threshold value, a speed abnormality signal is generated; Step 4: Based on the generated speed abnormality signal, a synchronization judgment value is calculated, and the synchronization judgment value is compared with the synchronization judgment threshold value. If the synchronization judgment value is greater than the synchronization judgment threshold value, a synchronization signal is generated; Step 5: Based on the above-generated synchronization signal, a target adjustment value of the wire clamp tension is calculated to optimize the cable take-up and arrangement speed.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0062] See also Figure 1 - Figure 2 As shown, the pressure sensor can detect and convert the measured physical quantity into a measurable signal. During the cable arrangement process, if the cables are arranged neatly and tightly, the pressure distribution between the cables and between the cables and the supporting structure will be relatively uniform. On the contrary, if the cables are not arranged neatly, the pressure distribution may be uneven. The present invention is a cable take-up and take-up control method of a cable take-up machine, comprising the following steps:

[0063] Step 1: In the process of cable winding, the pressure data of the cable winding is obtained and processed to calculate the evaluation value of the neatness of the cable winding;

[0064] In some embodiments, multiple detection points are set when the wire is collected and the total time of the wire collection process is divided into multiple detection time points;

[0065] At each detection time point, the pressure value of each detection point is obtained, and the pressure values ​​of all detection points are summed and averaged to obtain the pressure mean;

[0066] The pressure value of each detection point is calculated by difference with the pressure mean value, and the absolute value of the difference is marked as the pressure deviation value;

[0067] Comparing the pressure deviation value with a pressure deviation threshold, wherein the pressure deviation threshold is set by a person skilled in the art based on experience;

[0068] If the pressure deviation value is less than or equal to the pressure deviation threshold, it means that the deviation between the pressure value corresponding to the detection point and the pressure mean is small, and it is marked as a valid value;

[0069] If the pressure deviation value is greater than the pressure deviation threshold, it means that the deviation between the pressure value corresponding to the detection point and the pressure mean is large, and it is marked as an invalid value;

[0070] Obtain the number of values ​​marked as valid values, calculate the ratio of the number of valid values ​​to the number of detection points, and obtain the value of the valid data ratio, which is marked as the neatness evaluation value of the receiving and arranging wires;

[0071] It should be explained that the meaning of the cable collection and arrangement neatness evaluation value is as follows: the cable collection and arrangement neatness evaluation value is used to judge whether the cable collection and arrangement is neat at the detection time point, and is calculated by the number of values ​​marked as valid values, where the number of valid values ​​is the number of detection points where the deviation between the pressure value and the pressure mean is small, that is, the larger the valid value, the more uniform the pressure distribution at the detection time point, and the neater the cable collection and arrangement;

[0072] Step 2: Obtain the cable neatness evaluation value and evaluate the neatness of the cable neatness;

[0073] In some embodiments, a take-up and arrangement line regularity evaluation value is obtained at each detection time point, and the take-up and arrangement line regularity evaluation value is compared with a take-up and arrangement line regularity evaluation threshold;

[0074] The cable collection and arrangement neatness evaluation threshold is a critical value used to judge the neatness of the cable collection and arrangement, and is set by technicians in this field based on historical experimental data.

[0075] If the cable collection and arrangement neatness evaluation value is less than or equal to the cable collection and arrangement neatness evaluation threshold, it means that the cable collection and arrangement neatness at the detection time point meets the detection requirements, and a cable collection and arrangement neatness signal is generated;

[0076] If the cable collection and arrangement neatness evaluation value is greater than the cable collection and arrangement neatness evaluation threshold, it means that the cable collection and arrangement neatness at the detection time point does not meet the detection requirements, and a cable collection and arrangement irregularity signal is generated;

[0077] The core technology of this embodiment is: first, by obtaining the pressure values ​​of multiple detection points corresponding to the cable at each detection time point, the cable collection and arrangement neatness evaluation value is calculated, and the calculated collection and arrangement neatness evaluation value is compared with the collection and arrangement neatness evaluation threshold to determine whether a collection and arrangement neatness signal or a collection and arrangement irregularity signal is generated, so that the collection and arrangement neatness can be monitored and understood in a timely manner during the process of using the cable take-up machine to collect and arrange the cables, and then timely adjustments can be made according to the monitoring results, thereby reducing product performance problems and subsequent rework caused by irregular wiring, affecting production efficiency. Example 2

[0078] Based on the above embodiments, the present invention is a cable take-up and arrangement control method for a cable take-up machine, further comprising the following steps:

[0079] Step 3: Based on the evaluation result of the cable collection and arrangement neatness, the cable collection and arrangement speed data is obtained, the collection and arrangement speed judgment value is calculated, and the cable collection and arrangement speed is evaluated;

[0080] In some embodiments, two adjacent detection time points are marked as detection periods, and the take-up and delivery line speed data of each detection period is obtained;

[0081] In each detection period, the take-up and discharge line speed is compared with a take-up and discharge line speed threshold range (the take-up and discharge line speed threshold range is set by a person skilled in the art based on experience);

[0082] If the take-up and discharge line speed is within the take-up and discharge line speed threshold range, it means that the take-up and discharge line speed is in a normal state, and the take-up and discharge line speed is marked as normal;

[0083] If the take-up and discharge line speed is not within the take-up and discharge line speed threshold range, it means that the take-up and discharge line speed is in an abnormal state, and is marked as abnormal take-up and discharge line speed;

[0084] Obtain the value marked as the normal duration of the take-up and take-up wire speed, sum the normal duration values ​​of the take-up and take-up wire speed generated in the detection period to obtain the total value of the normal speed time, calculate the ratio of the total value of the normal speed time to the time value of the detection period, and obtain the normal speed time ratio;

[0085] Substitute the winding and discharging line speed value in the detection period into the variance formula to calculate the winding and discharging line speed variance value in the detection period;

[0086] Substitute into the formula , calculate the speed judgment value SP, where ZC represents the normal speed time ratio, FC represents the winding and traversing speed variance value, and a1 and a2 are preset proportional coefficients;

[0087] It should be explained that the speed judgment value reflects the following meaning: the speed judgment value is calculated by the normal speed time ratio and the winding and traversing speed variance value, that is, the smaller the normal speed time ratio value is, the longer the duration of the speed abnormality is, the smaller the speed judgment value is, and the more abnormal the speed is; that is, the larger the winding and traversing speed variance value is, the greater the speed fluctuation is during the detection period, the smaller the speed judgment value is, and the more abnormal the speed is;

[0088] Compare the speed judgment value with the speed judgment threshold, wherein the speed judgment threshold is set by a person skilled in the art based on historical multiple experimental data;

[0089] If the speed judgment value is less than or equal to the speed judgment threshold, it means that the cable take-up and take-up speed during the detection period meets the take-up and take-up speed specification, and a normal speed signal is generated;

[0090] If the speed judgment value is greater than the speed judgment threshold, it means that the cable take-up and take-up speed during the detection period does not meet the take-up and take-up speed specification, and a speed abnormality signal is generated;

[0091] Step 4: Based on the generated speed abnormality signal, calculate the synchronization judgment value and judge the correlation between the take-up and take-up line regularity and the take-up and take-up line speed;

[0092] In some embodiments, obtaining a detection time point corresponding to the generation of a speed abnormality signal and a corresponding detection time point value;

[0093] Obtain the detection time point corresponding to the generation of the uneven receiving and traversing line signal and the corresponding value of the detection time point;

[0094] Extract the detection time points that coincide with the detection time points corresponding to the generation speed abnormality signal and the detection time points corresponding to the generation of the irregular take-up and discharge line signal, mark them as coincident time points, and obtain the values ​​of the coincident time points;

[0095] Calculate the ratio of the number of overlapping time points to the number of detection time points corresponding to the generated speed abnormal signal to obtain the proportion of overlapping time points;

[0096] Obtain the line-reeling neatness evaluation value and the speed judgment value corresponding to the coincident time point, and plot them in the XY coordinate system respectively, connect the coordinate points corresponding to the line-reeling neatness evaluation value to obtain a line graph of the line-reeling neatness evaluation value, and connect all the coordinate points corresponding to the speed judgment values ​​to obtain a line graph of the speed judgment value;

[0097] Taking adjacent overlapping time points as an analysis period, marking the line segment corresponding to the line gathering and arranging neatness evaluation value corresponding to each analysis period as a line gathering and arranging neatness evaluation value sub-line, marking the line segment corresponding to the speed judgment value corresponding to each analysis period as a speed judgment value sub-line, and marking the line gathering and arranging neatness evaluation value sub-line and the speed judgment value sub-line corresponding to the same analysis period as a sub-line group;

[0098] The slopes of the line-collecting and arranging uniformity evaluation value sub-line and the speed judgment value sub-line in the sub-line group are respectively obtained, and the ratios are processed to obtain the sub-line synchronization ratio;

[0099] The sub-folding line synchronization ratios of all sub-folding line groups are summed up and averaged to obtain the sub-folding line synchronization ratio mean, and the sub-folding line synchronization ratios of the sub-folding line group are subjected to difference processing with the sub-folding line synchronization ratio mean to obtain the absolute value of the difference, which is marked as the sub-folding line synchronization ratio deviation value;

[0100] Compare the sub-broken line synchronization ratio deviation value with the sub-broken line synchronization ratio deviation threshold, wherein the sub-broken line synchronization ratio deviation threshold is set by a person skilled in the art based on a summary of multiple historical experimental data;

[0101] If the sub-folding line synchronization ratio deviation value is greater than the sub-folding line synchronization ratio deviation threshold, it is marked as an invalid sub-folding line group;

[0102] If the sub-folding line synchronization ratio deviation value is less than or equal to the sub-folding line synchronization ratio deviation threshold, it is marked as a valid sub-folding line group;

[0103] Get the value of the number of sub-polyline groups marked as valid, and perform ratio processing on the value of the number of sub-polyline groups marked as valid and the value of the sub-polyline groups to obtain the ratio of valid sub-polyline groups;

[0104] The proportion of overlapping time points is multiplied by the proportion of valid sub-broken line groups to obtain a synchronization judgment value;

[0105] It should be explained that the meaning reflected by the synchronization judgment value is: the synchronization judgment value is calculated by the proportion of overlapping time points and the proportion of valid sub-folding line groups, that is, the larger the proportion of overlapping time points, the higher the coincidence degree of the abnormality of the neatness of the winding and traversing line and the abnormality of the winding and traversing line speed, and the higher the synchronization, that is, the larger the proportion of the valid sub-folding line group, the larger the proportion of the sub-folding line synchronization ratio with a smaller deviation value, and the higher the synchronization;

[0106] Compare the synchronization judgment value with the synchronization judgment threshold, wherein the synchronization judgment threshold is set by a person skilled in the art based on a summary of multiple historical experimental data;

[0107] If the synchronization judgment value is less than or equal to the synchronization judgment threshold, it means that the irregularity of the take-up and take-up wires is less related to the abnormal speed of the take-up and take-up wires, and an asynchronous signal is generated;

[0108] If the synchronization judgment value is greater than the synchronization judgment threshold, it means that the irregularity of the take-up and take-up wires is highly correlated with the abnormal speed of the take-up and take-up wires, and a synchronization signal is generated;

[0109] Step 5: Based on the synchronization signal generated above, the target adjustment value of the wire clamp tension is calculated to optimize the wire collection and delivery speed;

[0110] In some embodiments, obtaining a detection time point corresponding to when the emission line irregularity signal is generated;

[0111] Obtain the previous detection period corresponding to the detection time point, mark it as the calculation period, obtain the speed data of the calculation period, sum and average the speeds of the detection period, and obtain the speed average;

[0112] Obtain the wire clamp tension data during the calculation period, sum and average the wire clamp tensions during the calculation period, and obtain the wire clamp tension average;

[0113] Substitute into the formula , the target adjustment value MB of the wire clamp tension is calculated, where ZJ represents the mean value of the wire clamp tension, SJ represents the mean value of the speed, and SB represents the standard value of the speed;

[0114] Exemplarily, the speed standard value is calculated by summing and averaging the maximum value and the minimum value of the speed threshold range;

[0115] It should be explained that in the process of cable collection and tracing, there is a close relationship between the tension of the wire clamp and the speed of cable collection and tracing. The size of the wire clamp tension will directly affect the stability and smoothness of the cable in the process of cable collection and tracing, and then affect the speed of cable collection and tracing. When the speed of cable collection and tracing is abnormal, by adjusting the tension of the wire clamp, the force of the cable in the process of cable collection and tracing can be changed, and then the speed of cable collection and tracing can be adjusted;

[0116] The core technology of this embodiment is: by acquiring speed data when the cable is not neatly collected and arranged, calculating the speed judgment value based on the acquired speed data, and then comparing the speed judgment value with the speed judgment threshold to generate a normal speed signal or a speed abnormality signal, and calculating the synchronous judgment value of the speed abnormality and the uneven cable collection and arrangement based on the acquired speed abnormality signal, to determine whether the uneven cable collection and arrangement is caused by the speed abnormality. If so, the target adjustment value of the wire clamp tension is calculated to optimize the cable collection and arrangement speed. If not, other influencing factors are analyzed and judged, so as to evaluate the reasons for the uneven cable collection and arrangement, and make timely adjustments based on the evaluation results, so as to improve the production efficiency of the cable collection and arrangement, and reduce the subsequent rework problems and the impact on product performance caused by the uneven cable collection and arrangement.
