Description

Technical Field

[0001] This application relates to the field of cable protection, and particularly to a method, device and equipment for controlling the coating of cable anti-corrosion grease. Background Art

[0002] For the bare conductor used in overhead transmission lines, the corrosion resistance of the conductor is improved by coating anti-corrosion grease on the surface of one or more stranded layers of the conductor, thereby extending the service life of the conductor. During the coating process, it is necessary to control the coating thickness appropriately. If it is too thick, it is easy to overflow from the gap, resulting in unstable lines. If it is too thin, the protection is insufficient.

[0003] The existing grease coating equipment uses an open-type manual oil extraction and pneumatic oil coating or automatic oil extraction method to realize the process of pumping and coating the conductor surface. The oil coating process relies on the naked eye observation of employees, and it is impossible to ensure the coating thickness and uniformity. For ordinary low-viscosity anti-corrosion grease, oil extraction and coating can be realized. However, for high-viscosity anti-corrosion grease, due to its high viscosity, the grease is likely to form an uneven coating or even no oil in stages on the conductor surface during the coating process. Especially in winter, the temperature drop affects the uniformity and continuity of grease coating. Summary of the Invention

[0093] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0094] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0095] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0096] The equipment required for cable anti-corrosion grease coating mainly includes:

[0097] The pay-off rack is used to place the cables to be coated, ensuring that the cables are released smoothly and stably during the pay-off process to avoid problems such as wire jamming and tangling. The pay-off rack should have a stable structure that can bear the weight of the cables, and the height and position can be adjusted as needed to meet the pay-off requirements of cables of different specifications.

[0098] In the coating equipment, the oil pressure plate applies a certain amount of pressure to the anti-corrosion grease on the cable through its own gravity or additional force. This pressure can ensure that the anti-corrosion grease is evenly squeezed out from the oil outlet and flows steadily to the cable surface, thereby achieving precise control of the amount of cable anti-corrosion grease coating. For example, in some automated coating production lines, the pressure of the oil pressure plate can be precisely adjusted according to the cable specifications and coating requirements to ensure that each section of cable can obtain the appropriate thickness of anti-corrosion grease coating.

[0099] Gear pump is a commonly used fluid delivery equipment. Through a pair of meshing gears rotating in the pump housing, the volume between the teeth changes continuously, thereby achieving the suction and discharge of liquid. Since the speed and displacement of the gear pump are relatively stable, the amount of anti-corrosion grease delivered per unit time can be accurately controlled to ensure the stability and consistency of the coating process.

[0100] The stranding equipment changes the original smooth surface structure of the wire core by stranding the wire cores. During the coating process, the coating material can better adhere to the gaps and uneven surfaces of the stranded wire cores. The length measuring wheel is arranged on the stranding equipment. By contacting and rotating with the wire core, the length measuring wheel accurately calculates the length of the wire core or the cable after stranding according to its circumference and the number of rotation turns. In the stranding equipment, the length measuring wheel can monitor the production length in real time during the cable production process. For example, when the stranding equipment is started, the length measuring wheel starts to rotate along with the conveyance of the wire core. Each rotation represents a certain length of cable passing through. By recording the number of rotation turns through devices such as sensors, the length data of the cable can be accurately obtained.

[0101] The existing grease coating equipment realizes the process of sucking and coating the surface of the conductor by means of open manual oil extraction, pneumatic oil coating or automatic oil pumping. The oil coating process relies on the naked eye observation of employees, and it is impossible to ensure the coating thickness and uniformity. For ordinary low-viscosity anti-corrosion grease, oil extraction and coating can be realized, but for high-viscosity anti-corrosion grease, due to its high viscosity, the grease is likely to form uneven coatings or even no oil in stages on the surface of the conductor during the coating process. Especially in winter, the decrease in temperature affects the uniformity and continuity of grease coating.

[0102] The cable anti-corrosion grease coating control method provided by this application aims to solve the above technical problems in the prior art.

[0103] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0104] Figure 1 is a schematic diagram of the scenario of cable anti-corrosion grease coating control provided by the embodiment of this application; as Figure 1 shown, the system provided by this embodiment includes a control unit 101, a pressure oil pan 102, a gear pump 103, a temperature sensor 104, an anti-corrosion grease heating device 105, a length measuring wheel encoder 106, an input unit 107, an image acquisition device 108, and a stranding equipment 109.

[0105] Among them, the pressure oil pan 102 is used to apply pressure to evenly extrude the anti-corrosion grease from the oil outlet and flow towards the surface of the cable;

[0106] The gear pump 103 is used for sucking and discharging liquids to realize fluid transportation, and conveys the anti-corrosion grease from the storage tank to the pressure oil pan 102;

[0107] The temperature sensor 104 is arranged at the oil outlet of the oil outlet pipe of the pressure oil pan 102 and is used to monitor the temperature of the anti-corrosion grease in the oil outlet pipe;

[0108] An anti-corrosion grease heating device 105 for heating the oil outlet pipe;

[0109] A meter wheel encoder 106 is arranged on the stranding equipment 110 for recording the length of the cable and the operation conditions of starting and stopping of the meter wheel;

[0110] An input unit 107 for inputting cable property data and preset oil output data;

[0111] An image acquisition device 108 for acquiring images of the cable coated with anti-corrosion grease;

[0112] A control unit 101 for controlling the oil pressing plate 102, the gear pump 103, the anti-corrosion grease heating device 105 and the stranding equipment 109.

[0113] Figure 2 It is a schematic flowchart of the cable anti-corrosion grease coating control method provided by an embodiment of the present invention. The execution subject of this embodiment can be Figure 1 the control unit in the illustrated embodiment, as Figure 2 shown, and the cable anti-corrosion grease coating control method specifically includes the following processes:

[0114] Step S201: Obtain cable property data, measured length data, preset oil output data and image information of the coated cable; obtain coating information by processing the image information and cable property data; analyze the anti-corrosion grease coating weight according to the coating information, cable property data and measured length data; adjust the pressure of the oil pressing plate and the rotation speed of the gear pump according to the anti-corrosion grease coating weight and the preset oil output data.

[0115] Specifically, the coating information is the thickness data of the anti-corrosion grease coated on the cable. The anti-corrosion grease coating weight on the cable can be calculated through the density information, thickness data and measured length in the cable property data. According to the analyzed anti-corrosion grease coating weight and the preset oil output data, the pressure of the oil pressing plate and the rotation speed of the gear pump are adjusted. When the actual coating weight is lower than the weight corresponding to the preset oil output, the pressure of the oil pressing plate can be appropriately increased or the rotation speed of the gear pump can be increased to increase the oil output; when it is higher than the weight corresponding to the preset oil output, the pressure of the oil pressing plate is reduced or the rotation speed of the gear pump is decreased. Through adjustment, it is ensured that during the stranding process, the cable can obtain an appropriate amount of anti-corrosion grease coating, avoiding waste caused by excessive oil or insufficient oil affecting the anti-corrosion effect.

[0116] Step S202: Obtain the type of anti-corrosion grease and the temperature of the anti-corrosion grease; adjust the temperature of the anti-corrosion grease heating device according to the type of anti-corrosion grease and the temperature of the anti-corrosion grease.

[0117] Specifically, the heating device is sleeved outside the oil outlet pipe and is used to heat the anti-corrosion grease in the oil outlet pipe; the oil outlet pipe is fixed between the oil outlet of the gear pump and the oiling gun barrel; the temperature sensor is arranged at one end of the oil outlet pipe close to the oiling gun barrel and is used to monitor the temperature of the anti-corrosion grease in the oil outlet pipe.

[0118] Since different types of anti-corrosion greases have different melting points and suitable coating temperature ranges, for example, high-viscosity anti-corrosion grease such as 40A240, due to its high viscosity, it is easy to form stagewise oil-free on the surface of the wire during the coating process, especially in winter, which affects the appearance and the uniformity of grease coating. Different models of cable anti-corrosion greases have different physical properties. By obtaining the type of anti-corrosion grease and making targeted temperature adjustments, the usage requirements of multiple anti-corrosion grease models can be met. This makes the production process more flexible, keeps the anti-corrosion grease in good fluidity and adhesiveness, and enables it to be evenly coated on the surface of the cable.

[0119] Step S203: Obtain the image information and cable attribute data of the coated cable, process the image information and cable attribute data to obtain coating information, and analyze defect information based on the coating information and preset coating target data; adjust the pressure of the oil pressing disc, the rotation speed of the gear pump, and the preset target temperature based on the defect information.

[0120] Specifically, the image information of the coated cable can be obtained through a camera or other image acquisition devices, and the coating conditions on the surface of the cable can be identified, such as coating thickness, whether there are defects such as missed coating, etc. It can also identify situations such as oil spill according to actual needs. Through comprehensive analysis of this image information and cable attribute data, detailed coating information can be obtained. Compare the actual coating information with the preset coating target data (such as standard coating thickness range, uniformity requirements, etc.) to analyze and obtain defect information. Based on the defect information, adjust relevant equipment parameters (such as the pressure of the oil pressing disc, the rotation speed of the gear pump, and the temperature of the anti-corrosion grease heating device), which can correct problems such as uneven coating caused by inappropriate pressure of the oil pressing disc, oil volume deviation caused by abnormal rotation speed of the gear pump, and poor flow of anti-corrosion grease caused by inappropriate heating temperature, and ensure the coating quality.

[0121] The cable anti-corrosion grease coating control method provided by the embodiments of the present invention makes the anti-corrosion performance of the entire cable line more uniform by precisely controlling the coating amount of the anti-corrosion grease, ensuring that each section of the cable can be protected by an appropriate amount of anti-corrosion grease. This not only improves the anti-corrosion effect but also saves the usage amount of the anti-corrosion grease and effectively reduces the production cost. At the same time, through temperature control, different anti-corrosion greases can be kept in good fluidity and adhesiveness, enabling them to be evenly coated on the surface of the cable, improving the coating efficiency and quality, reducing manual intervention and errors, and ensuring the anti-corrosion effect of the cable.

[0122] This embodiment details the process of adjusting the pressure of the pressure oil disk and the rotational speed of the gear pump according to the coating weight of the anti-corrosion grease and the preset oil output data in the above embodiment. The specific implementation of this process includes:

[0123] Step a1: Compare the coating weight of the anti-corrosion grease with the preset oil output data.

[0124] Specifically, by comparing the coating weight of the anti-corrosion grease with the preset oil output data, it is determined whether the coating amount exceeds the expectation.

[0125] Step a2: If the coating weight of the anti-corrosion grease is greater than the preset oil output data, reduce the pressure of the pressure oil disk and lower the rotational speed of the gear pump.

[0126] Specifically, reducing the pressure of the pressure oil disk can lower the speed at which the anti-corrosion grease is pressed out from the liquid storage tank. After reducing the pressure, the amount of anti-corrosion grease entering the coating link decreases accordingly. At the same time, lowering the rotational speed of the gear pump will also reduce the delivery volume of the anti-corrosion grease. The rotational speed of the gear pump affects the flow rate and volume of the anti-corrosion grease in the pipeline. When the rotational speed decreases, the volume of anti-corrosion grease passing through the gear pump per unit time decreases.

[0127] Step a3: If the coating weight of the anti-corrosion grease is less than the preset oil output data, increase the pressure of the pressure oil disk and raise the rotational speed of the gear pump.

[0128] Specifically, increasing the pressure can push the anti-corrosion grease in the anti-corrosion oil barrel through the oil outlet pipeline more quickly, thereby increasing the coating amount. Raising the rotational speed of the gear pump can transport more anti-corrosion grease to the coating position per unit time to meet the requirement that the coating weight reaches the preset oil output data.

[0129] In the embodiment of the present invention, by comparing the coating weight of the anti-corrosion grease with the preset oil output data in real time and adjusting the pressure of the pressure oil disk and the rotational speed of the gear pump according to the result, the coating amount can always fluctuate within a small range around the preset value. The stable coating quality can ensure that the pipeline has good anti-corrosion performance throughout its entire length, avoiding problems such as corrosion leakage due to poor local coating.

[0130] This embodiment details the process of adjusting the temperature of the anti-corrosion grease heating device according to the type of anti-corrosion grease and the temperature of the anti-corrosion grease. The specific implementation of this process includes:

[0131] Step b1: Extract the corresponding target temperature range from the preset temperature control database according to the type of anti-corrosion grease.

[0132] Specifically, different types of anti-corrosion grease have different physical and chemical properties and different coating temperature ranges within which the anti-corrosion grease has good fluidity and curing characteristics. The preset temperature control database stores the target temperature range corresponding to each type of anti-corrosion grease. By extracting the target temperature range from the database, the appropriate temperature parameters can be accurately obtained according to the type of anti-corrosion grease currently in use.

[0133] Step b2: Compare the target temperature range with the anti-corrosion grease temperature.

[0134] Specifically, through the comparison, abnormal conditions of the anti-corrosion grease temperature can be detected in a timely manner, and it can be quickly determined whether the anti-corrosion grease temperature exceeds the normal range. If the actual temperature is higher than the maximum value or lower than the minimum value of the target temperature range, the temperature abnormality is immediately identified, and corresponding measures are taken to adjust the temperature to avoid coating quality problems caused by inappropriate temperature.

[0135] Step b3: When the anti-corrosion grease temperature is greater than the maximum value of the target temperature range, reduce the temperature of the anti-corrosion grease heating device until the anti-corrosion grease temperature is within the target temperature range.

[0136] Specifically, when the temperature is too high, send an instruction to the heating device to reduce its heating power or stop heating for a period of time. A cooling device can also be set up, such as a cooling fan or a cooling water circulation method. By starting the cooling device, the heat dissipation can be accelerated, so that the anti-corrosion grease temperature drops. By reducing the temperature, quality problems caused by high temperature of the anti-corrosion grease can be prevented. If the anti-corrosion grease temperature is too high, its performance may decline, such as aging, decomposition, thinning, etc. By reducing the temperature in a timely manner, it can be ensured that the anti-corrosion grease maintains good coating performance, such as appropriate viscosity, fluidity, and adhesion. At the same time, a stable temperature also helps to ensure the uniformity of coating and avoid problems such as coating thickness differences caused by high temperature.

[0137] Step b4: When the anti-corrosion grease temperature is less than the minimum value of the target temperature range, increase the temperature of the anti-corrosion grease heating device until the anti-corrosion grease temperature is within the target temperature range.

[0138] Specifically, through the increase in heating power and the improvement of heat transfer efficiency, the anti-corrosion grease can absorb more heat, and its temperature will gradually rise, so that the anti-corrosion grease reaches an appropriate viscosity and fluidity, thereby ensuring that it can be smoothly coated on the surface of the cable and form a uniform and firm anti-corrosion layer.

[0139] This embodiment ensures the viscosity and fluidity of the anti-corrosion grease through temperature adjustment, improves the coating uniformity and quality, and effectively avoids coating defects caused by too high or too low temperature.

[0140] This embodiment details the process of obtaining the coating information by processing the image information and cable attribute data in the above embodiment. The specific implementation of this process includes:

[0141] Step c1: Perform edge detection and contour extraction on the image information to obtain cable image information.

[0142] Specifically, based on the color or grayscale mutation information of the pixel points in the image, the edge position of the object is determined. Existing edge detection algorithms can be used, such as the Canny algorithm. It first smooths the image through a Gaussian filter to reduce noise, then calculates the gradient magnitude and direction of each pixel point in the image, and determines whether the pixel point is an edge point according to the gradient information. The edge points are connected into a complete contour line through methods such as chain code tracing. Starting from a starting point among the edge points, adjacent edge points are gradually connected according to preset rules (such as eight-neighborhood connectivity) to form a closed contour line. By analyzing the cable contour image, the specific area for measuring the cable diameter can be determined, avoiding measurement errors caused by interference from background objects or other factors, and improving the accuracy and reliability of obtaining the entire coating information.

[0143] Step c2: Extract the cable diameter data from the cable attribute data.

[0144] Specifically, the cable attribute data is a pre-stored set of information about cable specifications, etc. Extracting the cable diameter data from it is usually through database query or file reading, etc. According to the identification information such as the cable model and batch, the corresponding diameter value is found in the attribute data.

[0145] Step c3: Obtain the coating diameter data by measuring the cable diameter in the cable image information.

[0146] Specifically, an image measurement algorithm can be used to calculate the cable diameter; by selecting two opposite edge points on the cable contour in the image, the distance between the edge points is calculated as the diameter.

[0147] Step c4: Compare the coating diameter data with the cable diameter data to obtain the coating information, where the coating information is the thickness information of the anti-corrosion grease coated on the outer layer of the cable.

[0148] Specifically, through comparison, the coating thickness of the anti-corrosion grease on the outer layer of each section of the cable can be accurately obtained.

[0149] In the embodiment of the present invention, by performing edge detection and contour extraction on the image information to obtain cable image information, background interference can be effectively removed and the cable contour can be accurately located. The cable diameter data extracted from the cable attribute data is used to measure and compare the actual coating diameter in the cable image to obtain the coating information, that is, the anti-corrosion grease thickness information, providing data support for subsequent analysis.

[0150] This embodiment details the process of obtaining defect information based on coating information and preset coating target data in the above embodiment. The specific implementation of this process includes:

[0151] Step d1: Obtain difference data based on the coating information and the preset coating target data.

[0152] Specifically, the difference data can clearly quantify the gap between the actual coating result and the expected target. It shows in a specific numerical form whether the coating is too thick or too thin, providing an accurate data basis for the follow-up.

[0153] Step d2: Compare the absolute value of the difference data with the preset difference threshold.

[0154] Specifically, by comparing with the threshold, it can directly determine which cable segments have uniform coating and which may have defects, without complex calculations or analyses. For the cable segments corresponding to the difference data exceeding the threshold, further analysis is required to determine the defect type and cause; for the part within the threshold range, it can be considered to meet the production requirements, reducing unnecessary analysis work and effectively optimizing the quality control process.

[0155] Step d3: If the absolute value of the difference data is less than or equal to the preset difference threshold, the anti-corrosion grease coating of the cable corresponding to the image information is uniform.

[0156] Specifically, by determining that the coating of this part of the cable is uniform, it can ensure that the product can exert the expected anti-corrosion performance during subsequent use, thus better ensuring the stability of the overall product quality.

[0157] Step d4: If the absolute value of the difference data is greater than the preset difference threshold, the anti-corrosion grease coating of the cable corresponding to the image information has defects, and analyze the defect information based on the absolute value, coating information, and preset coating target data.

[0158] Specifically, when the absolute value of the difference data exceeds the preset threshold, it indicates that there is a large deviation between the actual coating and the preset target. At this time, it is necessary to comprehensively consider the magnitude of the absolute value of the difference, coating information (such as actual coating thickness, coating speed, etc.), and the preset coating target data to analyze the specific situation of the defect.

[0159] In some alternative embodiments, the process of analyzing the defect information based on the absolute value, coating information, and preset coating target data specifically includes:

[0160] Step e1: Compare the absolute value with the preset coating target data.

[0161] Specifically, through comparison, it can be quickly determined whether the actual coating meets the preset target. If the absolute value is close to or equal to the preset target data, it indicates that the coating is close to the ideal state; if the absolute value is much larger than the preset target data, it indicates that there is a large deviation in the coating, providing a preliminary basis for further analyzing the type of defect later.

[0162] Step e2: When the absolute value is less than or greater than the preset coating target data, the anti-corrosion grease coating of the cable corresponding to the image information is uneven.

[0163] Specifically, when the absolute value is less than or greater than the preset coating target data, it indicates that there is a large gap between the actual coating and the target coating.

[0164] Step e3: When the absolute value is equal to the preset coating target data, determine whether the coating information of the cable segment corresponding to the image information is equal to zero.

[0165] Specifically, when the absolute value of the difference data is equal to the preset coating target data, there are two cases: the first indicates that the actual coating is twice the preset coating target data, and the second indicates that there may be an oil breakage phenomenon in the coating.

[0166] Step e4: If the coating information is equal to zero, then there is an oil breakage in the coating.

[0167] Specifically, the coating information being equal to zero means that within the range of image detection, the presence of anti-corrosion grease is not detected, that is, there is an oil breakage during the coating process. The oil breakage may be due to the too low temperature of the anti-corrosion grease resulting in insufficient fluidity, or too small pressure of the oil pressing plate or too low rotational speed of the gear pump. In a possible implementation manner, a flow meter can also be set at the oil outlet pipe to monitor the oil output in real time, and an alarm is given when the oil output is zero and there is an oil breakage.

[0168] Step e5: If the coating information is not equal to zero, then the anti-corrosion grease coating of the cable segment corresponding to the image information is uneven.

[0169] Specifically, when the coating information is not equal to zero, the situation where the actual coating is twice the preset coating target data occurs, and the anti-corrosion grease coating is too thick.

[0170] In some optional implementation manners, the process of adjusting the pressure of the oil pressing plate, the rotational speed of the gear pump, and the temperature of the anti-corrosion grease heating device based on the defect information specifically includes:

[0171] Step m1: When the defect information is an oil breakage, increase the temperature of the anti-corrosion grease heating device and adjust the corresponding target temperature range extracted from the preset temperature control database.

[0172] Specifically, when there is an oil cut-off defect and the supply of anti-corrosion grease is insufficient during the coating process, by increasing the temperature of the anti-corrosion grease heating device, the remaining anti-corrosion grease can be made more fluid, its viscosity can be reduced, making it easier for the anti-corrosion grease to form a continuous coating on the cable, and reducing coating interruptions caused by oil cut-off. At the same time, extracting the corresponding target temperature range from the preset temperature control database for adjustment can ensure that the adjusted data reduces the possibility of oil cut-off in subsequent applications.

[0173] Step m2: When the defect information is that the anti-corrosion grease coating is uneven, compare the coating information with the preset coating target data.

[0174] Specifically, when the anti-corrosion grease coating is uneven, comparing the actual coating information with the preset coating target data can clarify whether the coating amount is too much or too little, accurately judge the type of uneven coating, and provide a clear direction for further adjustment. This quantitative comparison method helps to avoid errors in subjective judgment and makes the adjustment measures more targeted.

[0175] Step m3: If the coating information is greater than the preset coating target data, reduce the temperature of the anti-corrosion grease heating device, reduce the pressure of the oil pressing plate, and reduce the rotation speed of the gear pump.

[0176] Specifically, the coating information being greater than the preset coating target data indicates that there is too much anti-corrosion grease. Excessive coating may be due to the anti-corrosion grease having too good fluidity and too high a temperature resulting in too low a viscosity, causing the coating amount to exceed expectations; reducing the temperature can appropriately increase the viscosity of the anti-corrosion grease and reduce the coating amount. At the same time, reducing the pressure of the oil pressing plate and reducing the rotation speed of the gear pump can directly control the amount of grease output and the coating speed during the coating process, bringing the coating amount back to the normal range. The dynamic adjustment of the coating process is achieved without stopping the machine, improving the production efficiency and the stability of product quality.

[0177] Step m4: If the coating information is less than the preset coating target data, increase the temperature of the anti-corrosion grease heating device, increase the pressure of the oil pressing plate, and increase the rotation speed of the gear pump.

[0178] Specifically, increasing the temperature of the anti-corrosion grease heating device is to reduce the viscosity of the anti-corrosion grease, making it easier to be coated on the cable, thereby increasing the coating amount. Increasing the pressure of the oil pressing plate and increasing the rotation speed of the gear pump can directly increase the amount of grease output and speed up the coating speed during the coating process to solve the problem of insufficient coating amount.

[0179] The embodiments of the present invention can quickly and effectively change the coating state through the combined adjustment of multiple parameters, making the coating amount reach the preset target range, achieving the dynamic adjustment of the coating process without stopping the machine, and improving the production efficiency and the stability of product quality.

[0180] In some alternative embodiments, the above method further includes:

[0181] Step n1: Obtain the target coating length and the start / stop information of the length measuring wheel.

[0182] Specifically, the target coating length is the length data of the cable to be coated for this coating task; the start / stop information of the length measuring wheel reflects the operating condition of the stranding equipment. When the stranding equipment pauses operation, the counting of the length measuring wheel stops.

[0183] Step n2: Compare the measured length data with the target coating length.

[0184] Step n3: When the measured length data is equal to the target coating length, generate the operation pause information for the stranding equipment, the pressure oil pan and the gear pump.

[0185] Step n4: Control the operation of the stranding equipment, the pressure oil pan and the gear pump according to the operation pause information and / or the start / stop information of the length measuring wheel.

[0186] Specifically, the operation of the stranding equipment, the pressure oil pan and the gear pump can be controlled according to the operation pause information and / or the start / stop information of the length measuring wheel; when starting is required, after inputting the target coating length, it can be controlled to start, realizing the synchronous start and stop of the pressure oil pan, the gear pump and the stranding equipment, eliminating the link of manually operating each button one by one. The operator no longer needs to manually start and stop the anti-corrosion grease filling, reducing the misoperation caused by human factors and the oil spill situation when the stranding equipment stops running but the pressure oil pan and the gear pump are still running. When the stranding equipment reaches the target coating length or receives a stop signal, the start / stop linkage module will generate a corresponding stop instruction and send it to the control end of the pressure oil pan and the gear pump. The filling amount of the anti-corrosion grease can better match the stranding length of the cable, avoiding problems such as uneven coating, overcoating or undercoating caused by equipment asynchronization.
