Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a first embodiment of the present invention provides a method for controlling an automatic optical cable penetration, comprising the steps of:
s11, acquiring environmental temperature and humidity data, a part specification parameter and an optical cable specification parameter, wherein the part specification parameter comprises a sliding friction factor and a part inner diameter, and the optical cable specification parameter comprises an optical cable diameter, an optical cable quality, an optical cable length and an optical cable density;
S12, judging according to the environmental temperature and humidity data, and judging to continue to execute the operation of the optical cable penetrating parts when the environmental temperature and humidity data meet the preset temperature and humidity conditions;
S13, calculating according to the specification parameters of the parts and the specification parameters of the optical cable to obtain friction force, and obtaining ideal penetrating piece force according to the friction force and a preset tension coefficient, wherein the ideal penetrating piece force is the ideal penetrating piece force;
s14, calculating according to the specification parameters of the parts, the specification parameters of the optical cable and the ideal force of the parts to obtain ideal speed of the parts, wherein the ideal speed of the parts is the ideal speed of all parts which are not penetrated;
S15, calculating according to the ideal speed of the penetrating piece and the ideal force of the penetrating piece to obtain fitting coefficients of all the non-penetrating pieces;
S16, sorting all the fitting coefficients, and determining the parts with the largest fitting coefficients as target parts;
S17, generating a control command according to the ideal penetrating piece speed and the ideal penetrating piece strength corresponding to the target part, and sending the control command to a control end, wherein the control end penetrates out an optical cable from the target part according to the control command.
In step S11, real-time environmental temperature and humidity data, a part specification parameter and an optical cable specification parameter need to be acquired, wherein the part specification parameter includes a sliding friction factor and an inside diameter of the part, and the optical cable specification parameter includes an optical cable diameter, an optical cable quality, an optical cable length and an optical cable density, and the method includes:
It should be noted that, the temperature and humidity data of the operating environment are obtained by a temperature and humidity sensor, for example, a real-time temperature value can be collected by a temperature sensor (such as a thermocouple, a thermistor and an infrared temperature sensor), the real-time humidity value obtains the current environmental humidity information by using a humidity sensor (such as a capacitive humidity sensor and an impedance humidity sensor), the sensors are connected with an instrument and meter and provide accurate readings of the current environment or the internal temperature of the device, and the data are collected by a data acquisition module and transmitted to an environment judgment module to be used. The parts specification parameters include a sliding friction factor and a parts inner diameter, which are measured in advance at a set temperature and humidity and stored in a parts database. The method for acquiring the specification parameters of the parts comprises the step of acquiring the specification parameters of the parts by importing pre-stored external files. The cable specification parameters include cable diameter, cable quality, cable length and cable density, which are obtained by measuring at a set temperature and humidity and stored in a cable database. The method for acquiring the optical cable specification parameters comprises the step of acquiring the optical cable specification parameters by importing pre-stored external files.
It is worth to say that, the sliding friction factor of the parts is influenced by the environmental temperature and humidity data, and is a factor which varies with the environment, the sliding friction factor of the parts influences the friction force of the optical cable in the penetrating and scattering process, and the friction force influences the ideal penetrating force and the ideal penetrating speed of the parts. The inner diameter of the spare part determines whether the optical cable can pass through smoothly, and the tightness degree in the spare part passing process, the optical cable is damaged due to the fact that the inner diameter is too small, and the stability of the spare part and the optical cable is affected due to the fact that the inner diameter is too large.
It is worth noting that the diameter of the optical cable affects the path of the optical cable in the parts and the required space, and the optical cable with larger diameter needs the adjustment of the strength and angle of the parts when the optical cable is used for penetrating the parts. The mass of the cable determines the weight of the penetration into the interior of the component, affecting sagging and tension distribution during penetration. For example, when a larger mass of fiber optic cable is threaded into the splice, more force is required to maintain tension. The length of the cable affects the friction and traction forces during the process of threading the loose parts, for example, in a process where the cable needs to be threaded into a longer steel pipe, the cable is subjected to greater friction as it goes deeper into the steel pipe, and thus greater traction forces are required to complete the threading of the loose parts.
In step S12, it is determined that the operation of penetrating the optical cable through the optical cable assembly needs to be performed according to the environmental temperature and humidity data, and when the environmental temperature and humidity data meets a preset temperature and humidity condition, the method includes:
When the temperature data meet the preset optical cable temperature critical range and the spare part temperature critical range and the humidity data meet the preset optical cable humidity critical range and the spare part humidity critical range, judging that the optical cable spare part penetrating operation is continuously executed;
And when the temperature data does not meet the preset optical cable temperature critical range or the spare part temperature critical range or the humidity data does not meet the preset optical cable humidity critical range or the spare part humidity critical range, judging to execute the operation of replacing the operating environment.
It is worth to say that, in the judging process, the equipment executes to acquire the real-time transmitted temperature and humidity data and the preset temperature and humidity data of the related parts and the preset temperature and humidity data of the optical cable, after the environment judgment is passed, the operation of penetrating the optical cable into the parts is continuously executed, if the environment judgment is not passed, the equipment is required to send out related instructions to replace the operation environment, for example, cooling or humidifying is required, the computer analyzes the difference value between the operation environment temperature and the preset temperature and humidity data of the related parts and the preset temperature and humidity data of the optical cable, and transmits the difference value to the temperature control/humidity control device to increase or decrease the temperature and humidity.
Specifically, an excessively high temperature may cause the performance of the optical cable material to be reduced, and an excessively low temperature may cause the hardness of the optical cable to be increased, so that physical damage is caused to the optical cable in the process of threading and pulling, and the physical performance of the optical cable is affected, for example, the working temperature of a standard optical cable is-40 ℃ to +75 ℃, and the high temperature and the low temperature which can be born are different due to different compositions of each optical cable structure, so that an optical cable specification database needs to be established and taken at any time.
Specifically, the optical cable also has certain requirements on humidity, and too high humidity can cause the insulation of the optical cable to be damaged, and meanwhile, the sliding friction factor is increased. According to analysis of the moisture resistance property of the optical cable, the upper limit and the lower limit of the working environment humidity of the optical cable are within the range of minus 20 ℃ to plus 55 ℃. In addition, the relative humidity in the damp-heat test is not lower than 85%, so that different operating environments and temperatures are required to be selected according to different processes, the proper operating environment can ensure the performances of the optical cable and the parts, and the service life of the optical cable after the parts are worn is prolonged.
In particular, ambient humidity has an effect on the attenuation characteristics of the fiber. For example, changes in humidity can cause expansion or contraction of the fiber material, thereby affecting the transmission performance of the fiber, resulting in increased signal attenuation. In the field of communication, signal transmission quality is reduced, and stability and reliability of communication are affected.
In step S13, a friction force is obtained by calculating according to the specification parameters of the components and the specification parameters of the optical cable, and an ideal force for penetrating the components is obtained according to the friction force and a preset tension coefficient, wherein the ideal force for penetrating the components is an ideal force for all non-penetrating components, and the method comprises the following steps:
In one implementation, the cable specification parameter includes cable quality and the part specification parameter includes a sliding friction factor.
The friction is calculated by the following formula:
Wherein, In order for the friction force to be a function of the friction force,Is the reference temperatureAnd reference humidityThe sliding friction factor of the lower part of the sliding block,As a coefficient of sliding friction factor with temperature change,As a coefficient of sliding friction factor with humidity,As a reference to the temperature of the liquid,Is the reference humidity, T is the ambient temperature, H is the ambient humidity,G is the weight of the optical cable and g is the gravitational acceleration.
It should be noted that the sliding friction factor is a key parameter affecting friction force, and it is affected by temperature and humidity. Under different temperature and humidity conditions, the friction characteristics of the material surface can be changed, and the friction force in the actual environment can be more accurately simulated by introducing the temperature and humidity correction coefficients. In practical application, by measuring the surface friction coefficient of the optical cable, the surface performance parameters of the optical cable required in different application scenes can be determined, which provides assistance for the selection of different parts. The friction force calculation formula considers the influences of the quality of the optical cable, the sliding friction factor and the ambient temperature and humidity, and can improve the accuracy of wearing parts.
The ideal force for passing through the parts refers to the minimum force required for enabling the optical cable to smoothly pass through the parts under the condition of ensuring that the optical cable is not damaged by pulling or overstretched. The ideal force of the wearing parts is set by multiplying the friction force by a tension coefficient, wherein the tension coefficient is a preset value for adjusting the friction force to meet the specific wearing parts requirement.
Calculating the ideal force of the penetrating piece by the following formula:
Wherein, For ideal force for wearing parts, k is a pull function.
The automatic control system adjusts the pulling force of the parts penetrating equipment according to the calculated ideal parts penetrating force, and in the whole parts penetrating process, the system continuously monitors the friction force and the ideal parts penetrating force, so that the accuracy of operation is ensured. If the environmental conditions change, the system will recalculate and adjust the ideal force to penetrate the parts.
It should be noted that the ideal strength of the optical fiber cable is the optimum strength required to be applied during the operation of the optical fiber cable to ensure that the optical fiber cable passes through the optical fiber cable (e.g., pipe, conduit, etc.) safely and effectively. The ideal penetrating piece force is obtained through friction force and tension coefficient, the ideal penetrating piece force is obtained before penetrating the piece, the ideal penetrating piece force of the piece to be penetrated is stored in a computer, the ideal penetrating piece force and the ideal penetrating piece speed are calculated to obtain a fitting coefficient, and the fitting coefficient can be directly called when the piece is required to be used next time.
It should be noted that the determination of the tension coefficient k needs to consider the mechanical properties of the material, the experimental measurement result and the balance condition of force in practical application.
Illustratively, the method of determining k is such as hooke's law, in which the first step in determining k is to understand the elastic properties of the material, and the coefficient of tension k is closely related to the elastic properties of the material. The magnitude of the spring force is proportional to the amount of deformation of the spring, i.e., f=kx, within the elastic limit, according to hooke's law. Where k is the coefficient of tension, which describes an indicator of the elastic properties of a material or object, and represents the force required for a deformation per unit length, in N/m. By measuring the force of the spring under different elongations, the tension coefficient k can be calculated.
In step S14, calculating according to the specification parameters of the parts, the specification parameters of the optical cable and the ideal strength of the penetrating parts, to obtain an ideal speed of the penetrating parts, where the ideal speed of the penetrating parts is an ideal speed of all non-penetrating parts, and the method includes:
In one implementation, the part specification parameters include a coefficient of sliding friction, the cable specification parameters include cable density and cable length, and the ideal speed of the part is calculated in combination with the ideal strength of the part.
The ideal speed of the penetrating piece is calculated by the following formula:
Wherein, In order to achieve the ideal force for wearing the parts,In order to achieve the desired speed of penetration of the loose parts,Is the reference temperatureAnd reference humidityThe sliding friction factor of the lower part of the sliding block,For the density of the optical cable,For the length of the optical cable,Gravitational acceleration.
It should be noted that in physics, the magnitude of the friction force directly affects the motion state of the object, including the speed, the speed is inversely proportional to the friction force, and is directly proportional to the force acting on the object, the sliding friction factor, the optical cable density, the optical cable length and the gravity acceleration jointly form the friction force of the object, the ideal speed of the penetrating piece is affected by the sliding friction factor, the sliding friction factor is affected by the temperature and humidity of the operating environment, therefore, the ideal speed of the penetrating piece is a randomly changed value, the value needs to be adjusted according to the actual situation, and the ideal speed of the penetrating piece of all the penetrating pieces to be penetrated is obtained through calculation before the penetrating piece is operated and stored in a computer, so that the next call is convenient.
The first traction wheel is used for traction of the optical cable, so that the traction speed of the first traction wheel is too low, and the quality of a tension air bag is affected;
in step S15, calculating according to the ideal speed of the penetrating piece and the ideal force of the penetrating piece, to obtain fitting coefficients of all non-penetrating pieces, including:
The fitting coefficients are calculated by the following formula:
Wherein, For the fitting coefficient of the i-th part,Is the reference temperatureAnd reference humidityThe sliding friction factor of the lower part of the sliding block,For the density of the optical cable,For the length of the optical cable,Gravitational acceleration.
The fitting coefficient is calculated by taking the ideal speed of the penetrating piece and the ideal force of the penetrating piece into consideration, and the fitting coefficient of each piece and the optical cable under a preset operation environment is determined by the ideal speed of the penetrating piece and the ideal force of the penetrating piece, so that each piece can be penetrated and scattered under the most suitable condition, the efficiency of the penetrating and scattering process and the safety of the optical cable are improved, and the coefficient considers the influence factors of friction force, optical cable density, optical cable length and gravitational acceleration and is used for adjusting and optimizing the ideal speed of the penetrating piece and the ideal force of the penetrating piece.
Illustratively, the fitting coefficients play an adjusting and optimizing role in the control method of the automatic optical cable penetration. After the parts are threaded, the fitting coefficients can be used to evaluate the effect of the process of threading the parts and provide a reference and adjustment basis for future operations of threading the parts. For example, after the penetration operation is completed, the effect of the penetration may be evaluated by comparing the actual penetration speed and force with the theoretical calculated value based on the fitting coefficients, if the actual value deviates significantly from the theoretical value, indicating that there is inaccurate friction estimation or other unaccounted factors. According to the effect evaluation after penetrating the parts, the fitting coefficient can be used for adjusting and optimizing future penetrating parts operation, and if the actual penetrating speed is found to be too high to cause the damage of the optical cable, the theoretical penetrating speed can be reduced by increasing the fitting coefficient so as to reduce friction and protect the optical cable.
For example, to improve the accuracy of the fitting coefficients, after each pass operation, the fitting coefficients and data from the pass process may be recorded, which may continue to improve the pass process and increase production efficiency. For example, an adaptive adjustment and intelligent learning device may be added, and in continuous wearing parts operation, the fitting coefficient may be used by the adaptive adjustment and intelligent learning device to adjust the wearing parameters in real time to adapt to changing environmental conditions and optical cable characteristics.
In step S16, sorting all the fitting coefficients, and determining the part with the largest fitting coefficient as the target part, including:
Collecting all the fitting coefficients, and sorting the fitting coefficients in a descending order;
the target part is determined by the following formula:
Wherein T is a target part, The function is selected for the maximum value and,Is the fitting coefficient.
Wherein a maximum selection function is usedTo determine the part with the largest fitting coefficient, this function provides the part picture or number corresponding to the largest fitting coefficient.
Specifically, the target parts, namely the parts with the largest fitting coefficients, are the parts which are easiest to pass through in the penetrating and scattering process according to the temperature and humidity data of the current operating environment and the condition of the current equipment. After the target parts are determined, the parts penetrating operation of the target parts is preferentially carried out.
In actual operation, the control system can ensure that the target parts can smoothly pass through by finely adjusting the ideal penetrating piece force and the ideal penetrating piece speed according to the determined target parts, and meanwhile, the time for adjusting the speed and the force of the equipment is improved, the production efficiency is improved, and in the process of penetrating the target parts, the system monitors the actual penetrating piece speed and the actual penetrating piece force, adjusts in real time according to the requirement, and ensures the smooth proceeding of the penetrating process.
In step S17, a control command is generated according to the ideal speed of the penetrating member and the ideal strength of the penetrating member corresponding to the target part, and the control command is sent to a control end, where the control end penetrates the optical cable out of the target part according to the control command, and the method includes:
finding out the next target part according to the fitting coefficient;
Transmitting the next target part to a control end;
the control end controls the instruction adjusting equipment according to the ideal penetrating piece strength and the ideal penetrating piece speed of the next target part;
and executing the operation of the optical cable penetrating piece, and returning to the step of finding the next target penetrating piece according to the fitting coefficient so as to realize the repeated execution of the operation of the optical cable penetrating piece until the penetrating piece task is completed.
The control system generates corresponding control instructions according to the ideal penetrating piece speed and the ideal penetrating piece force corresponding to the target parts, wherein the control instructions comprise the identification or position information of the target parts, specific numerical values of the penetrating piece speed and specific numerical values of the penetrating piece force, and the control end adjusts the force and speed setting of the traction wheel of the penetrating piece equipment according to the control instructions to ensure that the penetrating piece ideal force matched with the penetrating piece ideal speed of the second target parts. The real-time performance of the control instruction needs to be ensured to ensure that the automatic penetrating equipment can respond and execute the operation in time.
It is worth noting that the above process is cycled until all the parts are passed through. Each cycle generates new control instructions according to the current target parts and adjusts the equipment parameters.
The working process of the present invention is described below by taking a more general scenario as an example. Please refer to fig. 2, which is a schematic diagram of a working scenario of the method of fig. 1.
