Description

Technical Field

[0001] The present invention relates to the technical field of automatic threading control, and in particular to a control method and device for automatic threading of optical cables. Background Art

[0002] At present, optical cables are widely used in the fields of Internet infrastructure, telephone networks, cable TV and enterprise networks. They can provide high bandwidth, strong anti-interference, long transmission distance and other advantages. In the process of producing optical cables, different specifications of loose parts or steel pipes need to be threaded in different occasions. Therefore, in order to improve the efficiency of optical cable production, automatic loose parts threading devices are often used in factory workshops to thread loose parts.

[0003] In the existing automatic threading device for loose parts, the threading control process is as follows: pass the optical cable through the puncture knife, and then pass it into the loose parts. The optical cable will then pass through the knife box, tension wheel A, clamp 1, tension wheel B, first traction wheel, second traction wheel, clamp 2, first tension meter; threading wheel C, second tension meter, threading wheel D, and then pass through the cable reel, and finally through the automatic tension airbag device to tension the optical cable to the construction requirements. When the optical cable comes out of the loose parts, it passes through the first tension wheel A and tension wheel B. There is clamp 1 in front of the first traction wheel and between the second traction wheel. Clamp 1 clamps the optical cable, so that the optical cable from the first tension wheel A and tension wheel B to the first traction wheel forms a barb shape, and then the first traction wheel rotates to stretch the optical cable forward to thread the loose parts.

[0004] However, in the existing control process of threading loose parts, the loose parts are piled into a plate in a random order. After the optical cable passes through the current loose parts, it cannot automatically obtain the next target loose parts and requires manual matching. At this time, the production line is in a shutdown state, resulting in low production efficiency when the optical cable is automatically threaded through loose parts. Summary of the invention

DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1 The first embodiment of the present invention provides a control method for automatically threading an optical cable, comprising the following steps: S11, obtaining environmental temperature and humidity data, component specification parameters, and optical cable specification parameters, wherein the component specification parameters include a sliding friction coefficient and an inner diameter of the component, and the optical cable specification parameters include an optical cable diameter, an optical cable quality, an optical cable length, and an optical cable density; S12, judging according to the ambient temperature and humidity data, and when the ambient temperature and humidity data meet the preset temperature and humidity conditions, determining to continue to perform the optical cable threading operation; S13, calculating according to the specification parameters of the loose parts and the specification parameters of the optical cable to obtain the friction force, and obtaining the ideal force for threading the loose parts according to the friction force and a preset tension coefficient, wherein the ideal force for threading the loose parts is the ideal force for all the unthreaded loose parts; S14, calculating according to the specification parameters of the loose parts, the specification parameters of the optical cable and the ideal force for threading the loose parts, to obtain an ideal speed for threading the loose parts, wherein the ideal speed for threading the loose parts is the ideal speed of all the parts that have not been threaded; S15, calculating according to the ideal speed of threading loose parts and the ideal force of threading loose parts to obtain fitting coefficients of all unthreaded loose parts; S16, sorting all the fitting coefficients, and determining the bulk component with the largest fitting coefficient as the target bulk component; S17, generating a control instruction according to the ideal speed and the ideal force of threading the target loose parts and sending it to the control end, and the control end passes the optical cable through the target loose parts according to the control instruction.

[0021] In step S11, it is necessary to obtain real-time environmental temperature and humidity data, component specification parameters, and optical cable specification parameters, wherein the component specification parameters include sliding friction coefficient and component inner diameter, and the optical cable specification parameters include optical cable diameter, optical cable quality, optical cable length, and optical cable density, including: It should be noted that the operating environment temperature and humidity data are obtained by temperature and humidity sensors. For example, the real-time temperature value can be collected by a temperature sensor (such as a thermocouple, a thermistor, an infrared temperature sensor), and the real-time humidity value uses a humidity sensor (such as a capacitive humidity sensor, an impedance humidity sensor) to obtain the current environmental humidity information. These sensors are connected to instruments and provide accurate readings of the current environment or the internal temperature of the device. The data is collected by the data acquisition module and transmitted to the environmental judgment module for use. The specification parameters of the loose parts include the sliding friction coefficient and the inner diameter of the loose parts. The sliding friction coefficient and the inner diameter of the loose parts are measured in advance at the set temperature and humidity and stored in the loose parts database. Then, the method for obtaining the specification parameters of the loose parts is specifically: obtaining the specification parameters of the loose parts by importing a pre-stored external file. The specification parameters of the optical cable include the diameter of the optical cable, the quality of the optical cable, the length of the optical cable and the density of the optical cable. The acquisition of the diameter of the optical cable, the quality of the optical cable, the length of the optical cable and the density of the optical cable is measured at the set temperature and humidity and stored in the optical cable database. Then, the method for obtaining the optical cable specification parameters is specifically: obtaining the optical cable specification parameters by importing a pre-stored external file.

[0022] It is worth noting that the environmental temperature and humidity data will affect the sliding friction coefficient of the loose parts. The sliding friction coefficient is a factor that varies with the environment. The sliding friction coefficient of the loose parts affects the friction of the optical cable during the loose parts. The friction will affect the ideal loose parts penetration force and the ideal loose parts penetration speed. The inner diameter of the loose parts determines whether the optical cable can pass through smoothly and the tightness during the loose parts penetration process. If the inner diameter is too small, it will cause damage to the optical cable, and if the inner diameter is too large, it will affect the stability of the loose parts and the optical cable.

[0023] It is worth noting that the diameter of the optical cable affects its path through the loose parts and the space required. Optical cables with larger diameters require adjustment of the force and angle of penetration when passing through loose parts. The mass of the optical cable determines the weight of the loose parts, which affects the sagging and tension distribution during the process. For example, when a heavy-duty optical cable is passed through a loose part, greater force is required to maintain tension. The length of the optical cable affects the friction and traction during the process. For example, in the process of passing the optical cable through a longer steel pipe, as the optical cable goes deeper into the steel pipe, the optical cable will be subject to greater friction, so greater traction is required to complete the passage.

[0024] In step S12, it is necessary to make a judgment based on the ambient temperature and humidity data. When the ambient temperature and humidity data meet the preset temperature and humidity conditions, it is determined to continue to perform the optical cable threading operation, including: When the temperature data meets the preset critical range of optical cable temperature and the critical range of loose parts temperature, and the humidity data meets the preset critical range of optical cable humidity and the critical range of loose parts humidity, it is determined to continue the operation of threading the optical cable through the loose parts; When the temperature data does not meet the preset cable temperature critical range or component temperature critical range, or the humidity data does not meet the preset cable humidity critical range or component humidity critical range, it is determined to perform the operation of changing the operating environment.

[0025] It is worth noting that during the judgment process, the device obtains the real-time transmitted temperature and humidity data and the preset temperature and humidity data of the relevant parts and the preset temperature and humidity data of the optical cable retrieved by the computer. After passing the environmental judgment, the optical cable threading operation continues. If the environmental judgment is not passed, the device needs to issue relevant instructions to change the operating environment. For example, if cooling or humidification is required, the computer analyzes the difference between the operating environment temperature and the preset temperature and humidity data of the relevant parts and the preset temperature and humidity data of the optical cable, and transmits the difference to the relevant cooling or humidification command to the temperature / humidity controller to increase or decrease the temperature and humidity.

[0026] Specifically, too high a temperature may cause the performance of the optical cable material to deteriorate, while too low a temperature may increase the hardness of the optical cable, causing physical damage to the optical cable during the pulling process, affecting the physical properties of the optical cable. For example, the operating temperature of the standard optical cable is: -40℃ ~ +75℃. Since each optical cable has a different structural composition and can withstand different high and low temperatures, it is necessary to establish an optical cable specification database for easy access at any time.

[0027] Specifically, optical cables also have certain requirements for humidity. Excessive humidity will damage the insulation of the optical cables and increase the sliding friction factor. According to the analysis of the moisture resistance of optical cables, the upper and lower limits of the working environment humidity of optical cables are between -20℃ and +55℃. In addition, the relative humidity in the wet heat test is not less than 85%. Therefore, different operating environment temperatures and humidity need to be selected according to different processes. A suitable operating environment can ensure the performance of optical cables and parts, and extend the life of the optical cables after the parts are worn.

[0028] Specifically, environmental humidity affects the attenuation characteristics of optical fibers. For example, changes in humidity can cause the expansion or contraction of optical fiber materials, thereby affecting the transmission performance of optical fibers and increasing signal attenuation. In the field of communications, this can lead to a decrease in signal transmission quality and affect the stability and reliability of communications.

[0029] In step S13, the friction force is calculated according to the specification parameters of the loose parts and the specification parameters of the optical cable, and the ideal force for threading the loose parts is obtained according to the friction force and the preset tension coefficient, wherein the ideal force for threading the loose parts is the ideal force of all unthreaded loose parts, including: In one implementation, the optical cable specification parameters include the optical cable mass, and the loose component specification parameters include the sliding friction factor.

[0030] The friction force is calculated by the following formula: in, is the friction force, is the reference temperature and reference humidity The sliding friction coefficient under is the coefficient of sliding friction factor varying with temperature, is the coefficient of sliding friction factor varying with humidity, is the reference temperature, is the reference humidity, T is the ambient temperature, H is the ambient humidity, is the mass of the optical cable, and g is the acceleration due to gravity.

[0031] It should be noted that the sliding friction coefficient is a key parameter that affects friction, and it will be affected by temperature and humidity. Under different temperature and humidity conditions, the friction characteristics of the material surface will change. By introducing the correction coefficients of temperature and humidity, the friction in the actual environment can be simulated more accurately. In practical applications, by measuring the surface friction coefficient of the optical cable, the surface performance parameters of the optical cable required in different application scenarios can be determined, which helps in the selection of different loose parts. The friction calculation formula takes into account the influence of optical cable quality, sliding friction coefficient, and ambient temperature and humidity, which can improve the accuracy of threading loose parts.

[0032] The ideal force for threading loose parts refers to the minimum force required to smoothly thread loose parts while ensuring that the optical cable is not pulled or overstretched. The setting of the ideal force for threading loose parts is based on the product of friction and the tension coefficient. The tension coefficient is a preset value used to adjust the friction to meet specific threading requirements.

[0033] The ideal force for threading loose parts is calculated by the following formula: in, is the ideal force for penetrating loose parts, and k is the tension function.

[0034] The automatic control system adjusts the pulling force of the threading equipment according to the calculated ideal threading force. During the whole threading process, the system continuously monitors the friction force and the ideal threading force to ensure the accuracy of the operation. If the environmental conditions change, the system will recalculate and adjust the ideal threading force.

[0035] It is worth noting that the ideal force for threading loose parts refers to the optimal force that needs to be applied to ensure that the optical cable passes through loose parts (such as pipes, conduits, etc.) safely and effectively during the operation of threading loose parts with optical cables. The ideal force for threading loose parts is obtained through friction and tension coefficients. The ideal force for threading loose parts is obtained before threading loose parts, and the ideal force for threading loose parts to be threaded is stored in the computer, and the fitting coefficient is calculated with the ideal speed of threading loose parts, and it can be directly called when the loose parts are needed next time.

[0036] It is worth mentioning that the determination of the tension coefficient k needs to consider the mechanical properties of the material, experimental measurement results, and the force balance conditions in practical applications.

[0037] For example, the method for determining k is such as Hooke's law. In Hooke's law, the first step in determining k is to understand the elastic properties of the material, and the tension coefficient k is closely related to the elastic properties of the material. According to Hooke's law, within the elastic limit, the magnitude of the spring force is proportional to the deformation of the spring, that is, F=kx. Here k is the tension coefficient, which describes an indicator of the elastic properties of a material or object, indicating the force required for the deformation per unit length, and the unit is N / m. By measuring the force of the spring under different stretches, the tension coefficient k can be calculated.

[0038] In step S14, the ideal speed of threading the loose parts is obtained by calculating according to the specification parameters of the loose parts, the specification parameters of the optical cable and the ideal force of threading the loose parts, wherein the ideal speed of threading the loose parts is the ideal speed of all the unthreaded loose parts, including: In one implementation, the specification parameters of the loose parts include the sliding friction coefficient, the specification parameters of the optical cable include the optical cable density and the optical cable length, and the ideal speed of threading the loose parts is calculated in combination with the ideal force for threading the loose parts.

[0039] The ideal speed for threading loose parts is calculated by the following formula: in, To achieve the ideal strength for wearing loose parts, To achieve the ideal speed for threading loose parts, is the reference temperature and reference humidity The sliding friction coefficient under is the cable density, is the length of the optical cable, is the acceleration due to gravity.

[0040] It should be noted that in physics, the magnitude of friction directly affects the motion state of an object, including speed. The speed is inversely proportional to the friction and directly proportional to the force acting on the object. The sliding friction coefficient, optical cable density, optical cable length, and gravitational acceleration together constitute the friction of the object. The ideal speed for threading loose parts is affected by the sliding friction coefficient, and the sliding friction coefficient is affected by the temperature and humidity of the operating environment. Therefore, the ideal speed for threading loose parts is a randomly changing value and needs to be adjusted according to actual conditions. Before the threading operation, the ideal threading force of all the parts to be threaded is obtained, and the ideal threading speed of all the parts to be threaded is calculated and stored in the computer for easy use next time.

[0041] Exemplarily, the threading speed affects the threading control process as follows: when the first traction wheel pulls the optical cable, its traction speed is too fast, resulting in increased tension of the optical cable, and the optical cable is easy to break; when the first traction wheel pulls the optical cable, its traction speed is too slow, resulting in reduced tension of the optical cable, affecting the quality of the tension airbag; In step S15, the fitting coefficients of all the un-loose parts are obtained by calculation according to the ideal speed of loose parts penetration and the ideal force of loose parts penetration, including: The fitting coefficients are calculated by the following formula: in, is the fitting coefficient of the ith component, is the reference temperature and reference humidity The sliding friction coefficient under is the cable density, is the length of the optical cable, is the acceleration due to gravity.

[0042] It should be noted that the calculation formula of the fitting coefficient takes into account the ideal speed and the ideal force for threading the loose parts. The fitting coefficient of each loose part with the optical cable under the preset operating environment is determined by the ideal speed and the ideal force for threading the loose parts of each loose part. This helps to ensure that each loose part can be threaded under the most suitable conditions, thereby improving the efficiency of the threading process and the safety of the optical cable. This coefficient takes into account the influencing factors of friction, cable density, cable length and gravitational acceleration, and is used to adjust and optimize the ideal speed and the ideal force for threading the loose parts.

[0043] Exemplarily, the fitting coefficient plays an adjustment and optimization role in the control method of automatic threading of optical cables. After threading the loose parts, the fitting coefficient can be used to evaluate the effect of the threading process and provide a reference and adjustment basis for future threading operations. For example, after the threading operation is completed, the effect of threading can be evaluated by comparing the difference between the actual threading speed and force and the theoretical calculated value based on the fitting coefficient. If the actual value deviates greatly from the theoretical value, it means that there are inaccurate friction estimates or other factors that are not considered. Based on the effect evaluation after threading the loose parts, the fitting coefficient can be used to adjust and optimize future threading operations. If it is found that the actual threading speed is too fast and causes damage to the optical cable, the theoretical threading speed can be reduced by increasing the fitting coefficient to reduce friction and protect the optical cable.

[0044] Exemplarily, in order to improve the accuracy of the fitting coefficient, after each threading operation, the fitting coefficient and the data during the threading process can be recorded, and these data can continuously improve the threading process and improve production efficiency. For example, an adaptive adjustment and intelligent learning device can be added. In the continuous threading operation, the fitting coefficient can be used for the adaptive adjustment and intelligent learning device to adjust the threading parameters in real time to adapt to the changing environmental conditions and optical cable characteristics. By collecting data from multiple threading operations, the adaptive adjustment and intelligent learning device can learn and optimize the fitting coefficient to improve the intelligence level of the threading process.

[0045] In step S16, all the fitting coefficients are sorted, and the bulk component with the largest fitting coefficient is determined as the target bulk component, including: Collect all the fitting coefficients and sort the fitting coefficients in descending order; The target parts are determined by the following formula: Among them, T is the target component, Select the function for the maximum value, is the fitting coefficient.

[0046] Among them, the maximum value selection function is used To determine the parts with the largest fitting coefficient, this function provides the pictures or numbers of the parts corresponding to the maximum fitting coefficient.

[0047] Specifically, the target component, that is, the component with the largest fitting coefficient, is the component that is easiest to pass through during the threading process according to the temperature and humidity data of the current operating environment and the current equipment conditions. After the target component is determined, the threading operation of the target component is performed first.

[0048] For example, in actual operation, the control system can ensure that the target parts can pass through smoothly by fine-tuning the ideal force and speed for penetrating the target parts according to the determined target parts, while increasing the time for the equipment to adjust the speed and force, thereby improving production efficiency. In the process of penetrating the target parts, the system monitors the actual speed and force for penetrating the parts, and makes real-time adjustments as needed to ensure the smooth progress of the penetrating process.

[0049] In step S17, a control instruction is generated according to the ideal speed and the ideal force of threading the target component and sent to the control end, and the control end passes the optical cable through the target component according to the control instruction, including: According to the fitting coefficient, find the next target component; Transmitting the next target parts to the control end; The control end adjusts the device according to the ideal force and speed control instructions for penetrating the next target loose parts; The operation of threading the optical cable through the loose parts is performed, and the step of finding the next target loose parts according to the fitting coefficient is returned to realize the operation of threading the optical cable through the loose parts repeatedly, until the task of threading the loose parts is completed.

[0050] For example, according to the ideal speed and force of threading the target parts, the control system will generate corresponding control instructions, which include the following: the identification or location information of the target parts, the specific value of the threading speed and the specific value of the threading force. The control end adjusts the force and speed setting of the traction wheel of the threading equipment according to the control instructions to ensure that the ideal threading force and the ideal speed of the second target parts match. The sending of control instructions needs to ensure real-time performance to ensure that the automatic threading equipment can respond and execute operations in a timely manner.

[0051] It is worth noting that the above process will be repeated until all parts are passed through. Each cycle will generate new control instructions according to the current target parts and adjust the device parameters.

[0052] The following describes the working process of the present invention using a common scenario as an example. Figure 2 , which is Figure 1 Schematic diagram of the working scenario of the method.

[0053] In this embodiment, the control method and device for automatically threading optical cables involve an automatic threading device consisting of a data acquisition module, an environment judgment module, a force acquisition module, a speed acquisition module, a fitting matching module, a sorting module, and a threading execution module. The device is intended to reduce downtime and improve the production efficiency of optical cable threading.

[0054] The process of wearing loose parts is as follows: Step 1: The optical cable threading system is started, and all threading equipment and sensors start working to prepare for the optical cable threading operation. Before the optical cable threading operation, the temperature and humidity sensors start working to obtain real-time temperature and humidity data and transmit them to the environment judgment module. At the same time, the computer retrieves the optical cable specification data and all the loose parts specification data for this operation and transmits them to the environment judgment module; Step 2: The environment judgment module compares the current temperature and humidity data with the preset temperature and humidity, and adjusts the operating environment temperature and humidity in time to enable the operation of wearing loose parts; Step 3: Before the optical cable is threaded through the loose parts, the force acquisition module and the speed acquisition module are used to obtain the ideal threading force and the ideal threading speed of all the loose parts to be threaded in advance, and the fitting coefficient is calculated by the fitting matching module; Step 4: sort all the parts to be threaded in descending order according to the fitting coefficients through the sorting module and place them in the area of ​​parts to be threaded; Step 5: The threading execution module obtains the ideal threading force and ideal threading speed of the above-mentioned threading parts. The traction wheel drags the optical cable according to the ideal threading force and ideal threading speed of the threading parts. During the threading operation, the actual threading speed and force are continuously monitored and compared with the ideal values.
