Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable management, in particular to a light and efficient cable self-winding protection system. BACKGROUND

[0002] In many fields such as industrial production, logistics transportation and energy transmission, as the key carrier of energy and signal transmission, the storage and protection of cables are always important issues in practice. Traditional cable storage relies on manual operation or simple mechanical structure. When facing the scene of storing multiple cables at the same time, it is easy to cause problems such as winding and excessive pulling, which not only affects the service life of the cable, but also may cause equipment failure and even safety accidents.

[0003] In the prior art, some automatic cable storage devices use a single driving mechanism to drive multiple cables to be wound synchronously. This way cannot differentiate the control according to the actual state of each cable. For example, when a cable has abnormal tension due to external environmental changes or its own aging, the synchronous winding mechanism cannot adjust the winding speed or force of the cable in time, causing the cable to bear unnecessary stress and accelerating wear and tear or breakage. At the same time, the traditional device lacks effective state monitoring means, and mostly only uses simple limit switches to determine whether the cable is wound in place, which cannot real-time sense the key parameters such as tension change and vibration of the cable during winding, and it is difficult to predict potential failure risks in advance.

[0004] In the scene of parallel storage of multiple cables, the materials, diameters and purposes of different cables are different, and their suitable winding forces and speeds are also different. Existing systems often use uniform winding parameters, ignoring the differences in individual characteristics of cables, resulting in some cables being in a state of being too tight or too loose during winding. Being too tight will damage the internal structure of the cable, and being too loose will easily cause winding between cables, increasing the difficulty of subsequent arrangement.

[0005] At the same time, the response mechanism of the traditional cable protection system is relatively lagging, and usually only starts protection measures after the failure occurs, which cannot realize real-time protection. For example, when a cable is about to break due to excessive tension, the system can only alarm after the breakage occurs, and cannot intervene in time at the fault germination stage, causing irreparable loss. In addition, most of the existing monitoring equipment is centrally deployed, the data transmission distance is long, and the signal is easy to be disturbed, resulting in delay in state judgment, further reducing the effectiveness of protection.

[0006] With the continuous improvement of industrial automation, higher requirements are put forward for the lightness, efficiency and intelligence of cable storage systems. Due to the problems of complex structure, high energy consumption and poor adaptability, the traditional system has been difficult to meet the needs of modern production scenes. How to realize the independent and accurate winding of multiple cables, real-time monitoring and dynamic control of cable state, and the construction of a quick response protection mechanism has become a problem to be solved in the development of cable storage and protection technology.

[0040] Compared with the prior art, the present application has the following advantages:

[0041] The lightweight and efficient cable self-winding protection system has significant advantages in multi-cable accommodation and protection scenarios. Compared with traditional cable accommodation devices, the system realizes independent winding control of each cable to be accommodated through the cooperation of multiple winding drive devices and winding guide assemblies in the winding drive module. The winding guide assembly in each winding sub-region can upload position feedback signals in real time, so that the winding drive device can adjust the winding action according to the position state of a single cable, avoiding the winding and pulling problems caused by state differences during synchronous winding of multiple cables.

[0042] The combination of the tension monitoring module and the state regulation module breaks through the limitation of traditional systems that rely only on limit switches for simple judgment. The vibration sensing device collects environmental vibration information from multiple positions in the cable accommodation area, and the tension acquisition device acquires tension data for each cable in real time. Based on these multi-dimensional information, the edge regulation device can comprehensively analyze the real-time state of the cable, accurately capture the subtle changes of the cable during winding, and realize all-round and deep perception of the cable state.

[0043] The protection execution module closely links real-time state monitoring and dynamic protection operation by establishing a protection execution model. Unlike the passive response of traditional systems after a fault occurs, this module can trigger protection operations in advance based on the real-time state of the cable. For example, when it is detected that the tension of a cable approaches a critical value, the system can immediately adjust the operating parameters of the corresponding winding drive device to reduce the winding force; if it is found that abnormal vibration in the area may affect multiple cables, the overall protection mechanism can be started simultaneously. This active prevention mode fundamentally reduces the possibility of cable damage and prolongs the service life of the cable.

[0044] The system adopts multiple edge regulation devices for distributed processing, avoids the delay problem caused by centralized data processing, and improves the efficiency of state judgment and protection execution. At the same time, the cooperative working mechanism between each module makes the system structure compact, without the need for complex additional equipment, meeting the needs of lightweight design, and being able to adapt to the cable storage and protection needs in different scenes, having strong practical value in the fields of industrial production and energy transmission.

[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0050] Please refer to Figures 1-4 The present application provides a lightweight and efficient cable self-winding protection system, which comprises a winding drive module, a tension monitoring module, a state regulation module and a protection execution module. The specific implementation steps are as follows:

[0051] The winding drive module comprises a plurality of winding drive devices and a plurality of winding guide assemblies arranged in the cable storage area. Each winding guide assembly is assembled on each cable to be stored, and each winding drive device is distributed with at least one winding guide assembly in the corresponding winding sub-region. The winding guide assembly continuously collects its own position information and converts it into a position feedback signal, which is uploaded to the corresponding winding drive device in the winding sub-region. The winding drive device adjusts the winding action of the cable to be stored according to the signal.

[0052] The tension monitoring module is composed of a plurality of vibration sensing devices and a plurality of tension acquisition devices. The plurality of vibration sensing devices are respectively installed at different positions of the cable storage area, covering each corner of the storage area, for sensing the vibration condition in the area. Each of the cables to be stored is equipped with a tension acquisition device, which acquires the tension information of the cable to be stored in real time, providing basic data for subsequent state judgment.

[0053] The state regulation module includes a plurality of edge regulation devices, which receive the vibration information collected by the plurality of vibration sensing devices and the tension information collected by the plurality of tension acquisition devices, and comprehensively analyze and process the information through built-in algorithms to determine the real-time state of the cable to be stored, which includes the tension of the cable, whether there is abnormal vibration, etc.

[0054] The protection execution module first builds a protection execution model of the cable storage area, which is pre-set based on the layout of the cable storage area, the characteristics of the cable and the common risk scenarios. During operation, the protection execution module continuously receives the real-time state of the cable to be stored uploaded by the plurality of edge regulation devices, and when the real-time state reaches the pre-set trigger condition in the model, the protection execution operation of the cable storage area is immediately started to avoid damage to the cable or safety hazards.

[0055] In embodiment 1, the tension acquisition device is integrated with a displacement sensor, a deformation sensor and a friction sensor, which work together with the tension sensing component to complete multi-dimensional acquisition of the tension information of the cable to be stored. The displacement sensor captures the spatial position change of the cable to be stored in the winding process in real time through laser ranging or Hall effect principle, not only records the axial displacement of the cable along the winding direction, but also monitors the radial deviation amplitude of the cable, and generates a set of displacement data containing three-dimensional coordinate changes every fixed time interval. The deformation sensor uses strain gauge or fiber Bragg grating technology, which is closely attached to the surface of the cable. When the cable changes in shape such as stretching, bending or twisting due to tension, the sensor can convert these micro deformations into changes in electrical signals, and output voltage or current signals proportional to the deformation amount through a signal conditioning circuit, accurately reflecting the physical shape change of the cable under different tension. The friction sensor is installed at the contact interface between the cable and the winding guide assembly, using piezoelectric or resistance sensing structure. When the cable moves relative to the guide assembly during winding, the sensor can detect the friction force and change frequency between the contact surfaces, and record the temperature change caused by friction, to determine whether the friction state between the cable and the guide assembly is stable.

[0056] The plurality of edge regulation devices are divided into a main edge regulation device and a plurality of secondary edge regulation devices, forming a hierarchical cooperative regulation architecture. The main edge regulation device establishes a connection with all vibration sensing devices through a wired or wireless communication module and receives vibration information uploaded by each vibration sensing device in real time. The vibration information includes parameters such as frequency, amplitude, and acceleration of vibration, and the main edge regulation device summarizes and preliminarily analyzes these parameters, generates adjustment instructions for the data collection frequency of the plurality of tension acquisition devices according to the analysis results, and sends the instructions to each tension acquisition device through bus communication.

[0057] Each secondary edge regulation device is connected to at least one tension acquisition device through a distributed network and is responsible for receiving tension information uploaded by the corresponding tension acquisition device. The tension information includes multiple sets of data collected by displacement sensors, deformation sensors, friction sensors, and tension sensing components, and the secondary edge regulation device performs timestamp alignment and format standardization processing on these data to eliminate data deviations between different sensors. Subsequently, the secondary edge regulation device calls the built-in state evaluation algorithm to perform feature extraction and pattern recognition on the processed data, identifying the running state characteristics of the cable under the current tension, such as tension fluctuation period, deformation accumulation trend, and friction coefficient change rate.

[0058] The main edge regulation device and the secondary edge regulation device maintain real-time communication through a heartbeat mechanism, and the main edge regulation device periodically sends synchronization signals to each secondary edge regulation device to ensure that the clocks of all devices are consistent and avoid data misjudgment due to time deviation. After completing the real-time state judgment of the cable, the secondary edge regulation device packages and uploads the state result to the main edge regulation device, which globally integrates the state results uploaded by each secondary edge regulation device to form a global understanding of the state of all cables to be stored in the entire cable storage area. When the vibration information of a certain area is abnormal, the main edge regulation device can send an enhanced monitoring instruction to the corresponding secondary edge regulation device, requiring it to increase the frequency and accuracy of the state evaluation of the related cable. The secondary edge regulation device then adjusts its allocation of computing resources according to the instruction, prioritizing the state monitoring of the cable in the abnormal area. This hierarchical regulation architecture not only enables distributed real-time monitoring of the state of the cable, but also ensures the stable operation of the entire system when facing complex working conditions through the global coordination of the main edge regulation device.

[0059] Embodiment 2: The main edge regulation device adjusts the data collection frequency of the plurality of tension acquisition devices based on the vibration information collected by the plurality of vibration sensing devices, and the specific process is as follows.

[0060] The tension acquisition device works according to a first preset acquisition frequency in the initial operation stage. The frequency is set according to the regular operation parameters of the cable storage area, including the average winding speed of the cable, the environmental vibration benchmark value, etc., which can meet the basic monitoring needs while avoiding resource waste caused by too high frequency. In this stage, the tension acquisition device continuously acquires the tension information of the cable to be stored, including the instantaneous value and change amplitude of the tension, and packs these information in a fixed format and uploads them to the corresponding secondary edge control device regularly.

[0061] A plurality of vibration sensing devices are distributed at different positions of the cable storage area, including the vicinity of the winding drive device, the cable turning node, the edge of the storage area, etc. These vibration sensing devices form a vibration monitoring network covering the entire storage area. These vibration sensing devices capture the vibration signals in real time, and the signal content includes the frequency, amplitude, duration and approximate direction of the vibration source. The vibration sensing devices convert the collected vibration information into digital signals through analog-to-digital conversion, and then send them to the main edge control device through wired or wireless transmission.

[0062] After receiving the vibration information uploaded by each vibration sensing device, the main edge control device classifies and processes it. First, the identification of each vibration sensing device is bound to the vibration information collected by it, and the monitoring position corresponding to each group of vibration data is determined. Then, the main edge control device calls the built-in vibration analysis program to analyze each parameter in the vibration information and compare it with the preset vibration threshold. The vibration threshold is determined according to the structural characteristics of the cable storage area, the equipment operation standard and other factors, including the upper limit of the amplitude corresponding to different frequency bands and the time threshold of continuous vibration. When at least one parameter in the vibration information collected by a vibration sensing device exceeds the corresponding preset threshold, the main edge control device marks the area where the vibration sensing device is located as a vibration abnormal sub-area.

[0063] In the layout of the cable storage area, each winding drive device is responsible for winding work in a specific range, which is its corresponding winding sub-area, and each winding sub-area has a preset correspondence relationship with the monitoring range of multiple vibration sensing devices. The main edge control device queries the preset correspondence table according to the vibration sensing device identification corresponding to the vibration abnormal sub-area to determine the winding sub-area to which the vibration abnormal sub-area belongs, and marks the winding sub-area as an abnormal winding sub-area. If multiple vibration abnormal sub-areas correspond to the same winding sub-area, the main edge control device will upgrade the abnormal level of the winding sub-area to reflect the severity of the vibration abnormality.

[0064] After determining the abnormal coiling sub-region, the main edge regulation device generates a data collection frequency adjustment instruction. The instruction contains the identification of the abnormal coiling sub-region, the list of tension collection devices that need to be adjusted, and the new collection frequency parameters. The first preset collection frequency is usually set to a lower value, which is suitable for monitoring the cable in normal operation state, and can reduce the device energy consumption and data transmission pressure while ensuring basic data collection. The second preset collection frequency is higher than the first preset collection frequency, and its value is determined according to the vibration abnormality degree of the abnormal coiling sub-region. The more serious the vibration abnormality, the higher the second preset collection frequency is set to achieve high-density collection of cable tension information.

[0065] The main edge regulation device sends the adjustment instruction to all tension collection devices in the abnormal coiling sub-region through the communication interface. After receiving the instruction, the tension collection device reconfigures the internal clock module and data collection module, and adjusts the time interval of data collection to a value corresponding to the second preset collection frequency. After the adjustment is completed, the tension collection device collects the tension information of the cable to be received according to the new collection frequency, and uploads the data to the corresponding secondary edge regulation device immediately after the collection is completed. At the same time, the tension collection device feeds back the frequency adjustment result to the main edge regulation device, and the main edge regulation device confirms the feedback result. If there is a tension collection device that has not been successfully adjusted, the main edge regulation device will resend the adjustment instruction until all target devices complete the frequency adjustment.

[0066] After the vibration state of the abnormal coiling sub-region returns to normal, the main edge regulation device continuously monitors the vibration information of the region. When all parameters in the vibration information fall within the preset threshold range and the duration reaches the preset stable time length, the main edge regulation device determines that the abnormal state of the coiling sub-region has been resolved, and then generates a frequency recovery instruction to adjust the data collection frequency of the tension collection devices in the region from the second preset collection frequency back to the first preset collection frequency.

[0067] Embodiment 3: Based on the vibration information collected by multiple vibration sensing devices, the vibration abnormal sub-region is determined, which needs to go through single device data processing, multi-time point analysis and region merging.

[0068] Each vibration sensing device works continuously according to a preset sampling interval, which is set according to the environmental characteristics of the cable receiving area to ensure that potential vibration changes can be captured. The sensing element built-in the vibration sensing device converts mechanical vibration into electrical signal. After the electrical signal passes through the filter circuit to remove high-frequency noise, it enters the analog-to-digital converter to convert it into digital signal. The digital signal contains the original waveform data of the vibration. Each vibration sensing device binds its own identification with the digital signal to form a complete vibration information package, which is sent to the main edge regulation device through a wired transmission link.

[0069] After receiving the vibration information packet, the main edge regulation device first checks the data packet to check the integrity and transmission error of the data. If there is an error, the main edge regulation device sends a retransmission request to the corresponding vibration sensing device. After the check is passed, the main edge regulation device extracts the original waveform data in the vibration information packet and calls the signal analysis module for processing. The signal analysis module converts the time domain waveform into a frequency domain spectrum by using Fourier transform, identifies the main frequency component in the vibration signal, and calculates the vibration intensity value at each time point by combining time domain feature analysis. The vibration intensity value is obtained by comprehensive weighting of parameters such as amplitude, acceleration peak value and energy density, and can quantitatively reflect the intensity of vibration at the time point.

[0070] For each vibration sensing device, the main edge regulation device arranges the vibration intensity values at multiple time points in time sequence to form a vibration intensity time sequence. The length of the time sequence is determined according to a preset analysis period, which covers enough sampling points to reflect the trend of vibration. The main edge regulation device configures a vibration intensity threshold and a duration threshold for each vibration sensing device. The vibration intensity threshold distinguishes the boundary between normal vibration and abnormal vibration, and the duration threshold specifies the duration of time that the vibration intensity exceeds the threshold.

[0071] The main edge regulation device performs sliding window analysis on the vibration intensity time sequence, with a window size of one tenth of the analysis period and a sliding step of one sampling interval. In each window, the number of times that the vibration intensity exceeds the vibration intensity threshold is counted. If the proportion of the number of times exceeds one third of the total number of sampling points in the window, and the duration of this state reaches the duration threshold, it is determined that there is a vibration anomaly in the time period corresponding to the window. When three consecutive windows are determined to be vibration anomalies, the main edge regulation device marks the location of the vibration sensing device as a vibration anomaly point.

[0072] The cable storage area is divided into multiple grid cells, each of which corresponds to a fixed physical space range, and the installation position of each vibration sensing device is associated with a specific grid cell. The main edge regulation device collects the grid cells corresponding to all vibration anomaly points, merges adjacent vibration anomaly grid cells, and forms a continuous area, which is a vibration anomaly sub-area. If the grid cells corresponding to the vibration anomaly points are not adjacent, they form independent vibration anomaly sub-areas. Each vibration anomaly sub-area contains a list of grid cells it covers, the vibration sensing device identifiers involved, and the abnormal start time, etc. The main edge regulation device stores this information in the abnormal area database and synchronously updates it to other devices of the state regulation module, providing a basis for subsequent roll-up sub-area anomaly judgment.

[0073] In the process of determining the vibration anomaly sub-region, the main edge regulation device will also grade the severity of the vibration anomaly. The grading basis includes the amplitude of the vibration intensity exceeding the threshold, the duration of the anomaly, and the number of grid cells involved. The severity is divided into three levels: slight, moderate, and severe. Different levels correspond to different processing priorities. The higher the severity level, the shorter the subsequent response speed requirement. The grading results will be issued along with the vibration anomaly sub-region information to guide the subsequent processing strategy for the winding sub-region.

[0074] In embodiment 4, when the secondary edge regulation device determines the real-time state of the cable to be accommodated based on the tension information of the cable to be accommodated collected by the corresponding tension collection device, it first performs data reception and preprocessing. Each tension collection device continuously collects displacement information, deformation information, and friction information of the cable to be accommodated at a set collection frequency, and sends these information to the corresponding secondary edge regulation device through a dedicated communication link after attaching a time stamp. After receiving the data, the secondary edge regulation device first checks the integrity of the data. If it finds that the data frame is missing or has a verification error, it immediately sends a retransmission request to the corresponding tension collection device to ensure that continuous multi-time point data sequences are obtained.

[0075] After completing data reception, the secondary edge regulation device starts the data denoising process. For displacement information, the secondary edge regulation device extracts its peak value, valley value, mean value, and change slope in the time domain to form displacement time domain features. At the same time, the displacement information is decomposed into different frequency bands through wavelet transform, and the energy proportion of each frequency band is calculated to obtain displacement frequency domain features. For deformation information, a similar processing method is used to extract the cumulative amount and change rate of the deformation variable on the time axis as deformation time domain features, and the main frequency components and corresponding amplitudes of the deformation information are obtained through Fourier transform as deformation frequency domain features. The processing of friction information focuses on the fluctuation range and mutation times of the friction coefficient as time domain features, as well as the frequency spectrum distribution characteristics of the friction signal as friction frequency domain features and friction time domain features.

[0076] The secondary edge regulation device calls a pre-trained multi-modal denoising model, which includes a feature fusion layer and a noise filtering layer. The feature fusion layer aligns the dimensions and assigns weights to the displacement frequency domain features, displacement time domain features, deformation frequency domain features, deformation time domain features, friction frequency domain features, and friction time domain features to form a comprehensive feature vector. The noise filtering layer processes the comprehensive feature vector through a convolutional neural network to identify and filter out environmental interference signals and device noise components, and outputs denoised displacement information, deformation information, and friction information.

[0077] Based on the denoised information, the secondary edge regulation device calculates the risk value of the cable to be accommodated. The calculation method is: wherein, represents the risk value, The displacement anomaly coefficient is determined by the degree of deviation between the actual displacement and the rated displacement range. This represents the deformation influence coefficient, calculated based on the ratio of the deformation to the maximum allowable deformation of the cable. This represents the friction risk coefficient, which is determined based on the extent to which the friction coefficient exceeds the safety threshold. These are the weighting coefficients for displacement, deformation, and friction, respectively, and their values ​​are preset based on the cable type and usage scenario. .

[0078] when When the risk level exceeds a preset threshold, the secondary edge control device sends a position query signal to the winding guide assembly on the cable to be retrieved. Upon receiving the signal, the winding guide assembly obtains its real-time coordinates through its built-in positioning module, generates a position feedback signal, and returns it to the secondary edge control device. The secondary edge control device combines this position feedback signal to determine the real-time position of the cable to be retrieved. Then, by combining this with denoised displacement, deformation, and friction information, it analyzes the cable's stress state, wear condition, and movement trend at the current position, ultimately determining its real-time status.

[0079] The parameter scheduling device in the status control module is connected to all tension acquisition devices and edge control devices via industrial Ethernet to obtain the data acquisition frequency of each tension acquisition device in real time. When a certain winding sub-area is marked as an abnormal winding sub-area, the parameter scheduling device identifies the cable to be wound up corresponding to the winding guide component in that area as an abnormal cable to be wound up, and the corresponding tension acquisition device is the abnormal tension acquisition device. The sub-edge control device originally corresponding to this tension acquisition device is listed as a sub-edge control device to be scheduled. The parameter scheduling device queries the current load of each sub-edge control device, which is comprehensively evaluated by the number of tension acquisition devices it is processing and the data processing latency. Based on the number of abnormal tension acquisition devices and the load of the sub-edge control devices to be scheduled, the parameter scheduling device reallocates the correspondence: if the load of the sub-edge control device to be scheduled is below the threshold, its correspondence with some abnormal tension acquisition devices is maintained; if the load is too high, some abnormal tension acquisition devices are assigned to other sub-edge control devices with lower loads, or a backup sub-edge control device is temporarily activated to undertake the monitoring task, ensuring that each abnormal tension acquisition device has a corresponding sub-edge control device for data processing. After the reallocation is completed, the parameter scheduling device updates the correspondence table between the edge control device and the tension acquisition device, and synchronizes it to the main edge control device and related secondary edge control devices to realize the dynamic allocation of monitoring resources.

[0080] In the embodiment 5, the protection execution module first receives the real-time state of the cable to be stored uploaded by the state regulation module through the internal data interface when triggering the protection execution operation of the cable storage area in real time. The real-time state contains multiple types of information, such as the current tension value of the cable, which is directly measured by the tension sensing component in the tension acquisition device; the displacement change rate of the cable per unit time, which is calculated from the data collected by the displacement sensor; the deformation degree of the cable due to tension, which is determined by the monitoring result of the deformation sensor; the friction coefficient of the cable when contacting the winding guide assembly, which is the detection data from the friction sensor; and the specific position coordinates of the cable in the cable storage area, which are obtained by analyzing the position feedback signal uploaded by the winding guide assembly. These information are arranged in chronological order to form a continuous state data stream, and the protection execution module analyzes the data stream in real time to extract the key parameters related to the cable abnormality judgment.

[0081] The protection execution module internally stores a preset abnormality level division standard, which is formulated according to the physical characteristics and use requirements of the cable. For example, cables of different materials have different maximum tension that can be withstood, and the corresponding tension abnormality threshold is also different; if the displacement change rate of the cable exceeds a certain value, it may mean that the winding process is stalled or speeding up; if the deformation degree exceeds the elastic range of the cable itself, it may cause permanent damage; and if the friction coefficient is too high, it may cause local overheating. The abnormality level is divided into multiple levels, each level corresponding to a range of key parameters, for example, a first-level abnormality may correspond to a tension slightly higher than the normal range but not exceeding the safety threshold, a stable displacement change rate, and a deformation and friction coefficient within the normal range; a second-level abnormality may correspond to a tension close to the safety threshold, a fluctuating displacement change rate, and a slight deformation beyond the elastic range; and a third-level abnormality may correspond to a tension exceeding the safety threshold, a rapidly rising displacement change rate, and a significant deformation and friction coefficient significantly exceeding the standard. The protection execution module compares the key parameters in the real-time state with the abnormality level division standard to determine the abnormality level to which the cable to be stored belongs.

[0082] The preset protection action library is stored in the local memory of the protection execution module, and the library contains protection execution instructions corresponding to each exception level. For example, for a first-level exception, the protection execution instruction can be "reduce the winding speed by 10%", which can relieve the tension by slowing down the winding speed; for a second-level exception, the instruction can be "reduce the winding speed by 30% and continue to monitor", which can further reduce the tension and strengthen the state tracking; for a third-level exception, the instruction can be "immediately execute emergency braking", which can stop the winding action to avoid cable breakage or damage. Each protection execution instruction also contains execution details, such as specific values of winding speed adjustment, triggering methods of emergency braking, state feedback requirements after execution, etc. The protection execution module retrieves the corresponding protection execution instruction from the preset protection action library according to the determined exception level, and performs integrity check on the instruction to ensure that the instruction format is correct and contains necessary execution parameters.

[0083] The protection execution module sends the protection execution instruction to the corresponding winding drive device through the control bus, and the instruction contains the identification of the target winding drive device to ensure accurate delivery. After receiving the instruction, the winding drive device decodes the instruction and extracts the operation type and parameters. If the instruction is a winding speed adjustment, the motor controller in the winding drive device adjusts the power frequency or voltage of the motor according to the parameters, changes the motor speed, and then adjusts the winding speed of the cable. The entire adjustment process is realized through closed-loop feedback, and the motor controller collects the current speed in real time and compares it with the target speed until the speed stabilizes within the range required by the instruction. If the instruction is emergency braking, the braking unit in the winding drive device is immediately started, and the winding mechanism is stopped by mechanical braking or electromagnetic braking, and the motor power supply is cut off to prevent misoperation.

[0084] During the protection execution operation, the protection execution module continuously receives the execution state information returned by the winding drive device, such as the current winding speed, whether the brake is effective, etc., to confirm whether the operation is performed as expected. If an exception occurs during the execution process, such as the winding speed not being adjusted according to the instruction or the brake being ineffective, the protection execution module will resend the instruction or trigger a higher level of protection operation. After the operation is completed, the protection execution module stores the execution result and the real-time state update of the cable to be received together to form an operation log, which provides a reference for subsequent system maintenance.
