Description

Technical Field

[0001] The present invention relates to the technical field of cable management, and in particular to a lightweight and efficient cable self-winding protection system. Background Art

[0002] In fields like industrial production, logistics, and energy transmission, cables, as key carriers of energy and signal transmission, are crucial for their storage and protection. Traditional cable storage relies heavily on manual labor or simple mechanical mechanisms. When multiple cables are stored simultaneously, entanglement and excessive pulling are common, significantly impacting cable life and potentially causing equipment failures and even safety incidents. In the existing technology, some automated cable storage devices use a single drive mechanism to drive multiple cables to reel in synchronously. This method makes it difficult to perform differentiated regulation based on the actual status of each cable. For example, when a cable has abnormal tension due to changes in the external environment or its own aging, the synchronous retraction mechanism cannot adjust the retraction speed or force of the cable in time, causing the cable to be subjected to unnecessary stress, accelerated wear or breakage. At the same time, traditional devices lack effective status monitoring methods. Most of them only use simple limit switches to determine whether the cable is reeled in place. They are unable to perceive key parameters such as cable tension changes and vibration during the retraction process in real time, making it difficult to predict potential failure risks in advance. When storing multiple cables in parallel, the appropriate reeling force and speed vary depending on the cable's material, diameter, and purpose. Existing systems often use uniform reeling parameters, ignoring the differences in individual cable characteristics. This can cause some cables to be too tight or too loose during the reeling process. Overtightening can damage the cable's internal structure, while overly loosening can easily cause entanglement, making subsequent reeling more difficult. Furthermore, traditional cable protection systems have a delayed response mechanism, typically initiating protection measures only after a fault has occurred, making real-time protection impossible. For example, when a cable is about to break due to excessive tension, the system often only issues an alarm after the break occurs, failing to intervene in the incipient stage of the fault, causing irreversible damage. Furthermore, existing monitoring equipment is mostly deployed centrally, with long data transmission distances and signals susceptible to interference, resulting in delays in status assessment and further reducing the effectiveness of protection. The continuous advancement of industrial automation is placing higher demands on lightweight, efficient, and intelligent cable management systems. Traditional systems, due to complex structures, high energy consumption, and poor adaptability, are no longer able to meet the demands of modern production scenarios. Achieving independent and precise reeling of multiple cables, real-time monitoring and dynamic control of cable status, and establishing rapid-response protection mechanisms are pressing challenges in the development of cable management and protection technologies.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This lightweight, efficient cable self-reeling protection system demonstrates significant advantages in multi-cable storage and protection scenarios. Compared to traditional cable storage devices, this system achieves independent reeling control for each cable to be stored through the coordination of multiple reeling drive units and reeling guide components within the reeling drive module. The reeling guide components within each reeling sub-area transmit real-time position feedback signals, allowing the reeling drive unit to adjust the reeling action based on the position status of the individual cable, thus avoiding entanglement and pulling caused by state differences when reeling multiple cables simultaneously. The combination of the tension monitoring module and the state regulation module breaks through the limitation of the traditional system which only relies on limit switches for simple judgment. The vibration sensing device collects environmental vibration information from multiple positions in the cable storage area, and the tension collection device acquires real-time tension data for each cable. Based on these multi-dimensional information, the edge regulation device comprehensively analyzes the real-time state of the cable, and can accurately capture the subtle changes of the cable during the winding process. This multi-parameter fusion monitoring method can not only identify obvious problems such as tension abnormalities and excessive vibrations, but also can perceive potential risks caused by factors such as material fatigue and external interference, realizing comprehensive and deep perception of the state of the cable. The protection execution module closely connects 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 monitored that the tension of a certain cable approaches the critical value, the system can immediately adjust the operating parameters of the corresponding winding drive device to reduce the winding intensity; 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. The system uses multiple edge regulation devices for distributed processing, avoiding the delay problem caused by centralized data processing and improving the efficiency of state judgment and protection execution. At the same time, the cooperative working mechanism between modules makes the system structure compact, without the need for complex additional equipment, meeting the needs of lightweight design and being able to adapt to cable storage and protection requirements in different scenarios, having strong practical value in industrial production, energy transmission and other fields.

DETAILED DESCRIPTION

[0016] 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.

[0017] Please refer to Figures 1-4The present invention provides a lightweight and efficient cable self-winding protection system, which includes: a winding drive module, a tension monitoring module, a state control module, and a protection execution module. The specific implementation steps are as follows: The retraction drive module comprises multiple retraction drive devices and multiple retraction guide assemblies positioned within the cable storage area. Each cable to be stored is fitted with a retraction guide assembly, and each retraction drive device's corresponding retraction sub-area has at least one retraction guide assembly. The retraction guide assembly continuously collects its own position information, converts it into a position feedback signal, and transmits it to the retraction drive device corresponding to its retraction sub-area. The retraction drive device then adjusts its retraction action based on this signal.

[0018] The tension monitoring module consists of multiple vibration sensors and tension collection devices. These sensors are installed in various locations within the cable storage area, covering every corner and sensing vibrations within the area. Each stored cable is equipped with a tension collection device, which collects real-time tension information, providing essential data for subsequent status assessments.

[0019] The status control module includes multiple edge control devices, which receive vibration information collected by multiple vibration sensing devices and tension information collected by multiple tension collection devices. These devices use built-in algorithms to comprehensively analyze and process this information to determine the real-time status of the cables to be stored. The real-time status includes the tension of the cables, whether there are abnormal vibration effects, and other situations.

[0020] The protection execution module first constructs a protection execution model for the cable storage area. This model is pre-defined based on the cable storage area's layout, cable characteristics, and common risk scenarios. During operation, the protection execution module continuously receives real-time status updates of incoming cables from multiple edge control devices. When the real-time status meets the trigger conditions pre-set in the model, the protection execution module immediately initiates protection execution for the cable storage area to prevent cable damage or potential safety hazards.

[0021] In the 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 jointly complete the 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 reeling process in real time through laser ranging or Hall effect principle, and can not only record the axial displacement of the cable along the reeling direction, but also monitor the offset amplitude of the cable in the radial direction, and generate a set of displacement data containing three-dimensional coordinate changes every fixed time interval. The deformation sensor adopts strain gauge or fiber Bragg grating technology, and is closely attached to the surface of the cable. When the cable changes in shape due to tension, such as stretching, bending or twisting, the sensor can convert these micro deformations into changes in electrical signals, and output voltage or current signals proportional to the deformation 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 reeling guide assembly, and adopts a piezoelectric or resistive sensing structure. When the cable moves relative to the guide assembly during reeling, the sensor can detect the friction force between the contact surfaces and the change frequency, and record the temperature change caused by friction, so as to determine whether the friction state between the cable and the guide assembly is stable.

[0022] The plurality of edge regulation devices are divided into a main edge regulation device and a plurality of auxiliary 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 acquisition frequency of the plurality of tension acquisition devices according to the analysis results, and sends the adjustment instructions to each tension acquisition device through bus communication.

[0023] Each auxiliary 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 a plurality of sets of data collected by the displacement sensor, the deformation sensor, the friction sensor and the tension sensing component, and the auxiliary edge regulation device performs time stamp alignment and format standardization processing on these data to eliminate data deviation between different sensors. Subsequently, the auxiliary edge regulation device calls the built-in state evaluation algorithm to perform feature extraction and pattern recognition on the processed data, and identifies the running state characteristics of the cable under the current tension, such as tension fluctuation period, deformation accumulation trend and friction coefficient change rate.

[0024] The primary and secondary edge control devices maintain real-time communication via a heartbeat mechanism. The primary edge control device regularly sends synchronization signals to each secondary edge control device to ensure that all devices maintain clock consistency and avoid data misjudgment due to time deviation. After determining the real-time status of the cable, the secondary edge control device packages the status results and uploads them to the primary edge control device. The primary edge control device then globally integrates the status results uploaded by each secondary edge control device to form a comprehensive understanding of the status of all cables to be stored in the entire cable storage area. When vibration information in a certain area is abnormal, the primary edge control device can send enhanced monitoring instructions to the secondary edge control devices in the corresponding area, requesting them to increase the frequency and accuracy of their cable status assessments. The secondary edge control devices then adjust their computing resource allocation based on the instructions, prioritizing cable status monitoring in the abnormal area. This hierarchical control architecture not only enables distributed real-time monitoring of cable status, but also ensures stable operation of the entire system under complex working conditions through global coordination of the primary edge control devices.

[0025] Example 2: The main edge control device adjusts the data collection frequency of multiple tension collection devices based on the vibration information collected by multiple vibration sensing devices. The specific process is as follows.

[0026] During its initial operation, the tension collection device operates at a pre-set frequency. This frequency is based on the typical operating parameters of the cable storage area, including the average cable reeling speed and ambient vibration baseline. This frequency satisfies basic monitoring requirements while avoiding resource waste caused by excessively high frequencies. During this phase, the tension collection device continuously collects tension information from the stored cables, including instantaneous tension values ​​and fluctuations. This information is packaged in a fixed format and regularly uploaded to the corresponding secondary edge control device.

[0027] Multiple vibration sensors are distributed across the cable storage area, including key locations near the reel drive, at cable turning points, and at the edges of the storage area, forming a vibration monitoring network that covers the entire storage area. These sensors capture vibration signals at their locations in real time, including frequency, amplitude, duration, and the general direction of the vibration source. The sensors perform analog-to-digital conversion on the collected vibration information, converting it into a digital signal that is then transmitted to the primary edge control device via wired or wireless transmission.

[0028] After receiving the vibration information uploaded by each vibration sensing device, the main edge control device classifies and processes it. First, the identifier of each vibration sensing device is bound to the vibration information it collects, and the monitoring location corresponding to each set of vibration data is clarified. Subsequently, the main edge control device calls the built-in vibration analysis program to parse the various parameters in the vibration information and compare it with the preset vibration threshold. The vibration threshold is determined based on factors such as the structural characteristics of the cable storage area and the equipment operation standards, and includes the upper limit of the amplitude corresponding to different frequency bands, the time threshold for continuous vibration, etc. When there is at least one parameter in the vibration information collected by a vibration sensing device that exceeds the corresponding preset threshold, the main edge control device marks the area where the vibration sensing device is located as a vibration abnormality sub-area.

[0029] In the layout of the cable storage area, each reel drive is responsible for reeling within a specific range, which is its corresponding reel sub-area. Each reel sub-area has a preset correspondence with the monitoring ranges of multiple vibration sensing devices. The primary edge control device, based on the vibration sensing device identifier corresponding to the abnormal vibration sub-area, queries a preset correspondence table to determine the reel sub-area to which the abnormal vibration sub-area belongs and marks the reel sub-area as an abnormal reel sub-area. If multiple abnormal vibration sub-areas correspond to the same reel sub-area, the primary edge control device raises the abnormality level of the reel sub-area to reflect the severity of the vibration anomaly.

[0030] After determining the abnormal winding sub-area, the main edge control device generates a data acquisition frequency adjustment instruction. The instruction contains the identification of the abnormal winding sub-area, a 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 and is suitable for monitoring cables under normal operating conditions. It can reduce equipment energy consumption and data transmission pressure while ensuring basic data collection. The second preset collection frequency is higher than the first preset collection frequency. Its value is determined according to the degree of vibration abnormality in the abnormal winding sub-area. The more severe the vibration abnormality, the higher the second preset collection frequency is set to achieve high-density collection of cable tension information.

[0031] The main edge control device sends the adjustment instruction to all tension collection devices in the abnormal winding sub-area through the communication interface. After receiving the instruction, the tension collection device reconfigures the internal clock module and data collection module, and adjusts the data collection time interval 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 cables to be stored according to the new collection frequency, and immediately uploads the data to the corresponding secondary edge control device after the collection is completed. At the same time, the tension collection device feeds back the frequency adjustment result to the main edge control device, and the main edge control device confirms the feedback result. If there is a tension collection device that has not been successfully adjusted, the adjustment instruction will be resent until all target devices complete the frequency adjustment.

[0032] After the vibration state of the abnormal winding sub-area returns to normal, the main edge control device continues to monitor the vibration information of the area. When all parameters in the vibration information fall back to the preset threshold range and the duration reaches the preset stable time, the main edge control device determines that the abnormal state of the winding sub-area has been resolved, and then generates a frequency recovery instruction to adjust the data acquisition frequency of the tension acquisition device in the area from the second preset acquisition frequency to the first preset acquisition frequency.

[0033] Example 3: Determining abnormal vibration sub-regions based on vibration information collected by multiple vibration sensing devices requires steps such as single-device data processing, multi-time point analysis, and region merging.

[0034] Each vibration sensor operates continuously at a preset sampling interval, set based on the environmental characteristics of the cable storage area to ensure it captures potential vibration changes. The sensor's built-in sensing element converts mechanical vibration into an electrical signal. After filtering to remove high-frequency noise, the signal enters an analog-to-digital converter (ADC) for conversion to a digital signal. This digital signal contains the raw vibration waveform data. Each vibration sensor binds its identifier to the digital signal to form a complete vibration information packet, which is then sent to the master edge control device via a wired transmission link.

[0035] After receiving the vibration information packet, the primary edge control device first verifies the data packet for integrity and transmission errors. If any errors are found, it sends a retransmission request to the corresponding vibration sensing device. Once the verification is successful, the primary edge control device extracts the raw waveform data from the vibration information packet and calls the signal analysis module for processing. The signal analysis module uses a Fourier transform to convert the time domain waveform into a frequency domain spectrogram, identifying the primary frequency components in the vibration signal. Combined with time domain feature analysis, it calculates the vibration intensity value at each time point. The vibration intensity value is obtained by weighting parameters such as amplitude, peak acceleration, and energy density, and can quantitatively reflect the severity of the vibration at that point in time.

[0036] For each vibration sensing device, the master edge control device chronologically arranges the vibration intensity values ​​at multiple time points to form a vibration intensity time series. The length of the time series is determined by a preset analysis period, which covers a sufficient number of sampling points to reflect the changing trend of vibration. The master edge control device configures a vibration intensity threshold and a duration threshold for each vibration sensing device. The intensity threshold distinguishes between normal and abnormal vibration, while the duration threshold specifies how long the vibration intensity must persist after exceeding the threshold.

[0037] The primary edge control device performs a sliding window analysis on the vibration intensity time series, with a window size of one-tenth the analysis period and a sliding step of one sampling interval. Within each window, the device counts the number of times the vibration intensity exceeds the vibration intensity threshold. If this number exceeds one-third of the total number of sampling points within the window and the duration of this state exceeds the duration threshold, the device determines that a vibration anomaly exists within the time period corresponding to that window. If three consecutive windows are determined to have vibration anomalies, the primary edge control device marks the location of the vibration sensing device as a vibration anomaly point.

[0038] The cable storage area is divided into multiple grid units, each grid unit corresponds to a fixed physical space range, and the installation position of each vibration sensing device is associated with a specific grid unit. The main edge control device collects the grid units corresponding to all vibration anomaly points, merges adjacent vibration anomaly grid units, and forms a continuous area, which is the vibration anomaly sub-area. If the grid units corresponding to the vibration anomaly points are not adjacent, independent vibration anomaly sub-areas are formed respectively. Each vibration anomaly sub-area contains information such as the list of grid units it covers, the identification of the vibration sensing devices involved, and the start time of the anomaly. The main edge control device stores this information in the anomaly area database and synchronously updates it to other devices in the status control module to provide a basis for subsequent abnormal judgment of the winding sub-area.

[0039] During the process of identifying the vibration anomaly sub-areas, the main edge control device also classifies the severity of the vibration anomaly based on the magnitude of the vibration intensity exceeding the threshold, the duration of the anomaly, and the number of grid cells involved. Severity is divided into three levels: mild, moderate, and severe. Each level corresponds to a different processing priority. A higher severity level requires a shorter response time. The classification results are distributed along with the vibration anomaly sub-area information to guide the subsequent handling strategy for the rewinding sub-area.

[0040] Example 4: When the secondary edge control device determines the real-time status of the cable to be stored based on the tension information of the cable to be stored collected by the corresponding tension acquisition device, it first receives and pre-processes the data. Each tension acquisition device continuously collects the displacement information, deformation information and friction information of the cable to be stored according to the set acquisition frequency, and sends this information to the corresponding secondary edge control device through a dedicated communication link after attaching a timestamp. After receiving the data, the secondary edge control device first checks the integrity of the data. If it finds that the data frame is lost or the verification error is found, it immediately sends a retransmission request to the corresponding tension acquisition device to ensure that a continuous multi-time point data sequence is obtained.

[0041] After completing the data reception, the sub-edge control device starts the data denoising process. For the displacement information, the sub-edge control device extracts its peak value, valley value, mean value and change slope in the time domain to form the displacement time domain characteristics; 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 the displacement frequency domain characteristics. For the deformation information, a similar processing method is adopted to extract the cumulative amount and change rate of the deformation variable on the time axis as the deformation time domain characteristics, and the main frequency components and corresponding amplitudes of the deformation information are obtained through Fourier transform as the deformation frequency domain characteristics. The processing of friction information focuses on the time domain characteristics such as the fluctuation range of the friction coefficient and the number of mutations, as well as the spectrum distribution characteristics of the friction signal, as the friction frequency domain characteristics and friction time domain characteristics.

[0042] The secondary edge control device invokes a pre-trained multimodal denoising model, which consists of a feature fusion layer and a noise filtering layer. The feature fusion layer aligns and weights 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 using a convolutional neural network, identifying and filtering out environmental interference signals and device noise components, and outputs denoised displacement, deformation, and friction information.

[0043] Based on the denoised information, the secondary edge control device calculates the risk value of the cables to be stored. The calculation method is: in, represents the risk value, Indicates the displacement anomaly coefficient, which is determined by the degree of deviation between the actual displacement and the rated displacement range; Indicates the deformation influence coefficient, which is calculated based on the ratio of the deformation amount to the maximum allowable deformation amount of the cable; Represents the friction risk factor, which is determined by the magnitude by which the friction coefficient exceeds the safety threshold; are weight coefficients of displacement, deformation, and friction, respectively. Their values ​​are pre-set according to the cable type and usage scenario, and .

[0044] when When the risk value exceeds a preset threshold, the secondary edge control device sends a position query signal to the reel guide assembly on the cable to be stored. Upon receiving the signal, the reel guide assembly uses its built-in positioning module to obtain its real-time coordinates, generates a position feedback signal, and returns it to the secondary edge control device. The secondary edge control device uses this position feedback signal to determine the real-time position of the cable to be stored. It then analyzes the cable's stress state, wear, and movement trends in its current position, combining it with de-noised displacement, deformation, and friction information, ultimately determining its real-time status.

[0045] The parameter scheduling device in the state control module connects to all tension collection devices and edge control devices via industrial Ethernet, obtaining real-time data collection frequency information for each tension collection device. When a reeling sub-area is marked as an abnormal reeling sub-area, the parameter scheduling device identifies the cables to be stored corresponding to the reeling guide assembly within that area as abnormal cables. The corresponding tension collection device is designated as an abnormal tension collection device, and the secondary edge control device previously associated with that tension collection device is designated as the secondary edge control device to be scheduled. The parameter scheduling device queries the current load of each secondary edge control device, evaluating it based on the number of tension collection devices it is processing and the data processing latency. Based on the number of abnormal tension collection devices and the load of the secondary edge control devices to be scheduled, the parameter scheduling device reallocates the corresponding devices. If the load of a secondary edge control device to be scheduled is below a threshold, its corresponding device maintains its corresponding device. If the load is too high, some of the abnormal tension collection devices are assigned to other secondary edge control devices with lower loads, or a backup secondary edge control device is temporarily activated to take over monitoring tasks. This ensures that each abnormal tension collection device has a corresponding secondary 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 dynamic allocation of monitoring resources.

[0046] 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.

[0047] 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.

[0048] 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; and 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.

[0049] 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.

[0050] 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.
