The heating module includes a heating element and a heating head, the control area includes a display screen, operation buttons, and a microprocessor, and the signal strength detection module includes a power meter and an attenuator.
[0021] Based on the invisible optical cable wiring device shown in Figure 1 , an invisible optical cable wiring method is introduced. Figure 2
[0022] S201. Generate a three-dimensional model of the target room according to multiple images of the target room.
[0023] In the specific implementation process, the target room can be one room or multiple rooms. The user can take multiple images (photos or videos) of the target room from different angles, ensuring that all key parts of the target room are covered, and then input the multiple images of the target room into the invisible optical cable wiring device.
[0024] The central processing unit of the invisible optical cable wiring device includes an image and data processing module. The image and data processing module can pre-construct a convolutional neural network (CNN) model, train the CNN model on a large number of room images, and make it accurately extract the layout information of the target room. After obtaining the multiple images of the target room, the trained CNN model is used to process the images and identify the layout information of the target room.
[0025] The layout information includes geometric information and object information. The geometric information refers to the geometric shape of the target room, including the length, width, and height of the room, as well as the position and shape of structural elements such as walls, windows, and doors. For example, the layout of a rectangular, square, or irregular room, the length and angle of the wall, the opening direction of the window and door, etc. The object information refers to the specific position and arrangement of various objects (such as furniture, appliances, and decorations) in the room. For example, the position and distribution of sofas, beds, tables, and other furniture in the room, the position and distribution of televisions, air conditioners, and other appliances in the room, and their relative distances.
[0026] Further, the image and data processing module can construct walls, doors, windows, furniture, etc. based on the layout information extracted by the CNN through geometric modeling techniques such as polygon mesh, cube or other 3D geometric shapes. Then, the space layout is converted into a three-dimensional model using 3D graphics engine tools. The three-dimensional model can more intuitively show the overall and details of the target room, including the shape and height information of each part such as the ceiling, floor, and corner.
[0027] S202, obtaining position information of the existing invisible optical cable in the target room through the detection head.
[0028] In the specific implementation process, when the user presses the power button of the invisible optical cable wiring device, the display screen displays basic information and operation prompts. The user can place the detection head near the area in the target room where the invisible optical cable may exist. The detection head will automatically start detecting whether the invisible optical cable exists in the area and transmit the detection result (position information of the invisible optical cable) to the central processor.
[0029] The detection head can also transmit the position information of the existing invisible optical cable in the target room to the microprocessor of the control area, and the microprocessor controls the display screen to display the position information (including position coordinates, direction, and height) of the existing invisible optical cable in real time, helping the user to more intuitively view the detection result.
[0030] S203, generating a plurality of preset paths in the three-dimensional model according to the position information of the existing invisible optical cable and the preset wiring path parameters.
[0031] In the specific implementation process, the user can input the wiring path parameters to the microprocessor through the operation button, and the microprocessor transmits the wiring path parameters to the central processor. The wiring path parameters include the path starting point, the path ending point, the position of the device terminal to be connected, the minimum spacing, the minimum bending radius, and the maximum allowable tension.
[0032] After obtaining the wiring path parameters, the image and data processing module can also load the position information of the existing invisible optical cable in the three-dimensional model, use path planning algorithms (such as A* algorithm, Dijkstra algorithm, rapid random tree RRT, etc.) to find feasible paths in three-dimensional space with the wiring path parameters as constraints, and display the plurality of preset paths in different colors in the three-dimensional model. Each preset path should meet the following conditions: avoiding the position of the existing invisible optical cable (maintaining the minimum spacing), and meeting the preset wiring path parameters.
[0033] S204, determining a target path according to the plurality of preset paths.
[0034] In the specific implementation process, after generating the plurality of preset paths, the image and data processing module can send the plurality of preset paths to the microprocessor of the control area, and the microprocessor controls the display screen to display the plurality of preset paths, and the user can select a path as the target path from the plurality of preset paths by operating the button.
[0035] In a possible embodiment, the fitness function can be established according to the bending radius, the number of turns, the path length, the tension and the signal interference; the plurality of preset paths are optimized according to the fitness function to determine the target path.
[0036] In the specific implementation process, the expression of the fitness function is as follows: Fitness = w 1 ×f R +w 2 ×f T +w 3 ×f L +w 4 ×f S +w 5 ×f I wherein Fitness is the fitness, w 1 is the weight of the bending radius, w 2 is the weight of the number of turns, w 3 is the weight of the path length, w 4 is the weight of the tension, w 5 is the weight of the signal interference.
[0037]
[0038] wherein, f R is the fitness score of the bending radius, n is the total number of bending points in the current path, R k is the actual bending radius of the kth bending point, R min is the minimum bending radius allowed by the cable (determined by the material specification).
[0039] f T =1 -T max / T wherein, f T is the fitness score of the number of turns, T maxT is the maximum number of allowed turns, T is the actual number of turns of the current path (a change of direction ≥ 45° is counted as 1 turn).
[0040] f L = L min / L i wherein, f L is the fitness score of the path length, L i is the actual length of the current path, L min is the theoretically shortest length in the plurality of preset paths (which can be pre-calculated by A* algorithm).
[0041]
[0042] wherein, f S is the fitness score of the tension, max (Tension) is the maximum tension in the current path, T max is the maximum allowed tension.
[0043]
[0044] wherein, f I is the fitness score of the signal interference ，I total is the total interference exposure of the current path (related to the intensity of the interference source, the parallel length, and the distance), and a is the attenuation coefficient (adjusted according to the sensitivity, such as a = 0.1 for high-frequency signals).
[0045] In the embodiments of the present application, the fitness function is established based on the bending radius, the number of turns, the path length, the tension, and the signal interference, which can comprehensively consider multiple factors in the optical cable wiring, can reduce unnecessary path length and bending, optimize the wiring layout of the optical cable, can effectively reduce the waste of the optical cable, and thus reduce the construction cost. Moreover, reasonable planning and optimization of the wiring path can make the tension of the optical cable within a reasonable range, avoid excessive bending of the optical cable, enhance the mechanical properties of the optical cable, and also can reduce signal attenuation and improve signal transmission quality.
[0046] In a possible embodiment, the plurality of preset paths are optimized according to the fitness function to determine a target path, comprising: selecting a plurality of paths from the plurality of preset paths as an initial population; calculating, according to a fitness function, fitness of each path in the initial population; selecting two paths with the highest fitness from the initial population to perform crossover and mutation, forming a new path to be added to the initial population, and removing a path with fitness less than a preset threshold from the initial population until a convergence condition is reached, obtaining a target population; and determining a target path according to paths in the target population.
[0047] In a specific implementation process, k (such as k = 5) paths are randomly selected from the plurality of preset paths as the initial population, and the two paths with the highest fitness are reserved as parents. A crossover point (avoiding a bending sensitive area) is randomly selected, the subsequent segments of the parent paths are exchanged, the connection is smoothly connected (such as inserting a Bézier curve), a path point is randomly moved with a probability pm, and a segment of the path is replaced with a better sub-path with a probability pr, thereby generating a new path. The new path is added to the population, and a path with fitness less than a preset threshold (such as 0.5) is removed. The fitness of the population is continuously improved through iteration until a convergence condition is reached, obtaining the target population. The convergence condition includes a maximum number of iterations (for example, 200), fitness stagnation (for example, the optimal solution is continuously improved by less than <1% for 20 generations), and a constraint satisfaction rate (such as 95% of the paths satisfying all hard constraints).
[0048] In the embodiments of the present application, the optical cable routing path is gradually optimized by continuously improving the fitness, thereby minimizing signal interference, reducing loss, controlling tension, and ensuring the mechanical strength and construction efficiency of the optical cable.
[0049] There are various ways to determine the target path according to the paths in the target population, which will be introduced below.
[0050] The first way is to directly select the path with the highest fitness in the target population as the target path.
[0051] The second way is for the user to select a path from the target population as the target path.
[0052] In a specific implementation process, the paths in the target population can be sent to a microprocessor of the control area, and the microprocessor can control the display screen to display the plurality of preset paths, and the user can select a path from the target population as the target path by operating the button.
[0053] The third way is to input the paths in the target population into a path prediction model to obtain the target path; the path prediction model is trained based on historical routing data.
[0054] In the implementation process, the historical wiring data includes a plurality of historical wiring paths and feedback information (such as wiring time, wiring cost, path quality score, etc.) of each wiring path. The path prediction model is trained based on the historical wiring data, and the path prediction model is, for example, a regression model, a neural network, a support vector machine, etc. Finally, the target path in the target population is input into the trained path prediction model, and the target path is output.
[0055] In the embodiments of the present application, the historical wiring data is used to train the path prediction model, the target path can be predicted, and personalized path selection is provided for the user. With the passage of time and the accumulation of data, the accuracy and prediction ability of the model will continue to improve, thereby helping the user to make more efficient and economical wiring decisions.
[0056] S205, control the traction system to pull the target optical cable to advance along the target path.
[0057] In the implementation process, the user can press the start button of the traction system to start the traction system. Since the end of the traction system is connected to the target optical cable, the traction system will pull the target optical cable to advance along the preset path from the starting point until the target optical cable reaches the end point, and the traction system will automatically stop.
[0058] During the traction process, the traction system can send traction state information such as traction force, traction speed, and traction direction to the microprocessor of the control area, and the microprocessor can control the display screen to display these traction state information. The user can input the traction speed or the traction direction to the microcontroller by operating the button, and the microcontroller sends the traction speed or the traction direction to the traction system to adjust the traction speed or the traction direction.
[0059] In one possible embodiment, before pulling the target optical cable along the target path by the traction system, the method further comprises: adjusting the power of the heating element to keep the heating head within a preset temperature range; heating the self-adhesive of the target optical cable by the heating head, and sticking the target optical cable to the end of the traction system through the self-adhesive.
[0060] In the implementation process, if the target optical cable is a self-adhesive optical cable, the user can press the start button of the heating element to start the heating element to heat up and transfer heat to the heating head. When the heating head reaches the preset temperature range, the user places the heating head at the sticking position of the self-adhesive optical cable to preheat for a period of time to activate the self-adhesive. After the heating head activates the adhesion, the target optical cable is immediately stuck to the end of the traction system. During the sticking process, the target optical cable is ensured to be in close contact with the end of the traction system and maintain stable pressure, and the self-adhesive is ensured to be uniformly distributed on the contact surface to achieve the best adhesion effect.
[0061] In the embodiment of the present application, the self-adhesive is heated by the heating element and the heating head. The purpose of heating is to soften the adhesive layer of the optical cable, enhance the adhesion between the adhesive layer and the surface of the optical cable, improve the adhesive effect of the self-adhesive, firmly paste the optical cable and the traction system, and prevent the optical cable from being easily loosened and falling off, so as to ensure the stability and reliability of wiring.
[0062] In a possible embodiment, the power of the heating element in the heating module is adjusted, including: The current temperature of the heating element is obtained by the temperature sensor; and according to the current temperature and the preset temperature range, a PID control algorithm is used to automatically adjust the power of the heating element.
[0063] In the specific implementation process, the accuracy of the temperature sensor can reach ±1℃, the current temperature of the heating element can be monitored in real time, and the current temperature is fed back to the central processor. The central processor further includes a temperature adjustment system. The temperature adjustment system can use a PID (Proportion-Integral-Derivative) control algorithm to adjust the control amount by calculating the current error, the integral of the past error, and the differential of the error change, so as to realize the stable and accurate control of the target temperature. The output of the PID controller can be expressed as: PID output value = K p ×e(t) + K i ×∫e(t)dt + K d ×de(t) / dt Wherein, e(t) is the error at the current time, that is, the difference between the target temperature and the current temperature, the target temperature is the expected value of the preset temperature range, for example, 50℃. K p is the proportion coefficient, K i is the integral coefficient, and K d is the differential coefficient, ∫e(t)dt is the integral of the error, and de(t) / dt is the differential of the error.
[0064] Finally, the power of the heating element is automatically adjusted according to the PID output value. For example, when the output is positive, the power of the heating element is increased; when the output is negative, the power of the heating element is reduced; and when the output is close to zero, the current power of the heating element is maintained.
[0065] In the embodiments of the present application, the PID control algorithm can make accurate adjustments according to the difference between the target temperature and the current temperature, ensuring that the temperature can be stably maintained near the preset value, avoiding overheating or overcooling. PID control can automatically adjust system parameters, reducing manual operation and intervention. By adjusting the temperature through the PID algorithm, not only can temperature fluctuations be prevented, but also overheating of equipment or long-term operation in an inappropriate temperature range can be avoided. Such a control scheme helps to prolong the service life of the equipment and reduce the likelihood of failure.
[0066] In a possible embodiment, the central processor can send the current temperature of the heating element and the heating time to the microprocessor, and the microprocessor controls the display screen to display the current temperature and the heating time. The user can manually adjust the power of the heating element according to the actual situation by operating the button.
[0067] Considering that the prior art cannot timely detect damage, breakage or other abnormal conditions of the optical cable during the wiring process, once a problem occurs, detection and rework often need to be performed after the construction is completed, increasing construction costs and workload. Therefore, in a possible embodiment, while the target optical cable is pulled forward along the target path by the traction system, the method further comprises: obtaining the pulling force of the traction system through a pulling force sensor; obtaining the power and the attenuation of the target optical cable through a signal strength detection module; if any of the plurality of state parameters exceeds the corresponding preset range, displaying fault information through the display screen; the plurality of state parameters include the current temperature, the pulling force, the power and the attenuation.
[0068] In the specific implementation process, the pulling force sensor can monitor the pulling force of the traction system in the pulling process in real time and feed back to the central processor. The signal strength detection module can monitor the power of the target optical cable in real time through a power meter and feed back to the central processor, and the signal strength detection module can monitor the attenuation of the target optical cable in real time through an attenuator and feed back to the central processor. The central processor further comprises a fault detection module, which judges whether the plurality of state parameters including the current temperature, the pulling force, the power and the attenuation exceed the corresponding preset range, and if any of the state parameters exceeds the corresponding preset range, an alarm is sent in time, and the microprocessor sends the fault information to the microprocessor, which can control the display screen to display the fault information. The fault information includes the fault type and the fault position.
[0069] In the embodiments of the present application, by monitoring the traction tension, heating temperature, power and attenuation of the optical signal in real time, once an abnormal parameter is detected, an alarm is immediately sent out to prevent the problem from expanding or causing more serious consequences, avoid the damage of the equipment due to exceeding the safety range, and ensure the long-time stable operation of the equipment. By displaying the specific fault type and position, the user can quickly locate the problem, without the need for extensive troubleshooting, and can carry out targeted equipment maintenance, thereby improving the work efficiency.
