Description

Light-weight efficient cable self-rolling protection system

Technical Field

The invention relates to the technical field of cable management, in particular to a lightweight high-efficiency cable self-winding protection system.

Background

In a plurality of fields such as industrial production, logistics transportation, energy transmission and the like, cables are used as key carriers for energy and signal transmission, and storage and protection of the cables are always important subjects in practice. The traditional cable is stored and is relied on manual operation or simple mechanical structure, when facing the scene that many cables were accomodate simultaneously, very easily appear twining, drag excessive scheduling problem, not only influence the life of cable, still probably initiate equipment trouble even incident.

In the prior art, a part of automatic cable storage device adopts a single driving mechanism to drive a plurality of cables to be synchronously wound, and the mode is difficult to carry out differential regulation and control according to the actual state of each cable. For example, when a cable has abnormal tension due to external environmental change or aging, the synchronous winding mechanism cannot adjust the winding speed or strength of the cable in time, so that the cable is subjected to unnecessary stress and is accelerated to wear or fracture. Meanwhile, the traditional device lacks an effective state monitoring means, and most of the traditional device only judges whether the cable is wound in place through a simple limit switch, so that key parameters such as tension change and vibration condition of the cable in the winding process cannot be sensed in real time, and potential fault risks are difficult to prejudge in advance.

Under the scene of parallelly accomodating of multi-cable, there is the difference in the material, diameter, the usage of different cables, and its suitable roll-up dynamics, speed are also different. The existing system often adopts uniform winding parameters, ignores the difference of individual characteristics of cables, and leads to the situation that part of cables are in an overtightening or overtightening state in the winding process. Too tightly can make cable inner structure impaired, and the too loose then causes the winding between the cable easily, increases the degree of difficulty of follow-up arrangement.

Meanwhile, the response mechanism of the traditional cable protection system is lagged, and protection measures are usually started after faults occur, so that real-time protection cannot be realized. For example, when a cable is about to break due to excessive tension, the system can only alarm after the occurrence of the break, but cannot intervene in time in the fault germination stage, and the loss caused by the fault germination stage cannot be recovered. In addition, most of the existing monitoring equipment is deployed in a centralized way, the data transmission distance is long, signals are easy to interfere, and the state judgment is delayed, so that the effectiveness of protection is further reduced.

Along with the continuous promotion of industrial automation degree, the weight reduction, the high efficiency, the intelligent of cable storage system have put forward higher demands. The traditional system has difficulty in meeting the requirements of modern production scenes due to the problems of complex structure, high energy consumption, poor adaptability and the like. How to realize independent and accurate winding of a plurality of cables, monitor and dynamically regulate and control the states of the cables in real time, and construct a fast-response protection mechanism becomes a problem to be solved in the current cable storage and protection technology development.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1-4, the invention provides a lightweight and efficient cable self-rolling protection system, which comprises a rolling driving module, a tension monitoring module, a state regulating module and a protection executing module. The specific implementation steps are as follows:

The winding driving module comprises a plurality of winding driving devices and a plurality of winding guide components, wherein the winding driving devices and the winding guide components are arranged in the cable storage area. Each cable to be accommodated is provided with a winding guide assembly, and at least one winding guide assembly is distributed in a winding area corresponding to each winding driving device.

The tension monitoring module consists 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 accommodating area, cover all corners of the accommodating area and are used for sensing vibration conditions in the area. Each cable to be accommodated is provided with a tension acquisition device, and the tension acquisition device acquires tension information of the cable to be accommodated in real time and provides basic data for subsequent state judgment.

The state regulation and control module comprises a plurality of edge regulation and control devices, the devices receive vibration information acquired by a plurality of vibration sensing devices and tension information acquired by a plurality of tension acquisition devices, and the information is comprehensively analyzed and processed through a built-in algorithm, so that the real-time state of the cable to be received is determined, and the conditions of the tension of the cable, whether abnormal vibration influence exists or not and the like are covered in the real-time state.

The protection execution module firstly builds a protection execution model of the cable containing area, and the model is preset based on the layout of the cable containing area, the cable characteristics and the common risk scene. In the operation process, the protection execution module continuously receives the real-time state of the cable to be accommodated, which is uploaded by the plurality of edge regulation and control devices, and when the real-time state reaches the preset triggering condition in the model, the protection execution operation of the cable accommodating area is immediately started so as to avoid the damage or the potential safety hazard of the cable.

In the embodiment 1, the tension acquisition equipment is integrated with a displacement sensor, a deformation sensor and a friction sensor, and the sensors and the tension sensing component work cooperatively to finish multi-dimensional acquisition of the tension information of the cable to be accommodated. The displacement sensor captures the spatial position change of the cable to be accommodated in the winding process in real time through the laser ranging or Hall effect principle, so that the axial displacement of the cable along the winding direction can be recorded, the radial offset amplitude of the cable can be monitored, and a group of displacement data containing three-dimensional coordinate change can be generated at fixed time intervals. The strain gauge or the fiber bragg grating technology is adopted by the deformation sensor, the strain gauge or the fiber bragg grating technology is closely attached to the surface of the cable, when the cable is subjected to form changes such as stretching, bending or torsion due to the action of tension, the sensor can convert microscopic deformations into changes of electric signals, and voltage or current signals in direct proportion to deformation are output through the signal conditioning circuit, so that the physical form changes of the cable under the action of different tension are accurately reflected. The friction sensor is arranged at the contact interface of the cable and the winding guide assembly, and adopts a piezoelectric or resistance type induction structure, when the cable and the guide assembly relatively move in the winding process, the sensor can detect the friction force and the change frequency between contact surfaces, and meanwhile, the temperature change caused by friction is recorded, so that whether the friction state between the cable and the guide assembly is stable or not is judged.

The edge regulation and control devices are divided into a main edge regulation and control device and a plurality of auxiliary edge regulation and control devices, so that a layered cooperation regulation and control framework is formed. The main edge regulating and controlling equipment is connected with all the vibration sensing equipment through a wired or wireless communication module, and vibration information uploaded by each vibration sensing equipment is received in real time. The vibration information comprises parameters such as frequency, amplitude, acceleration and the like of vibration, the main edge regulating and controlling equipment collects and primarily analyzes the parameters, generates an adjustment instruction for data acquisition frequency of the tension acquisition equipment according to an analysis result, and sends the adjustment instruction to the tension acquisition equipment in a bus communication mode.

Each auxiliary edge regulating device is connected with 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 comprises a plurality of groups of data collected by the displacement sensor, the deformation sensor, the friction sensor and the tension sensing component, and the auxiliary edge regulating and controlling equipment performs time stamp alignment and format standardization processing on the data to eliminate data deviation among different sensors. And then, the secondary edge regulating and controlling equipment invokes a built-in state evaluation algorithm, performs feature extraction and pattern recognition on the processed data, and recognizes the running state features of the cable under the current tension action, such as a tension fluctuation period, a deformation accumulation trend, a friction coefficient change rate and the like.

The main edge regulating device and the auxiliary edge regulating devices keep real-time communication through a heartbeat mechanism, and the main edge regulating device periodically sends synchronous signals to the auxiliary edge regulating devices, so that the clocks of all the devices are ensured to be consistent, and data misjudgment caused by time deviation is avoided. After the auxiliary edge regulating equipment completes the judgment of the real-time state of the cable, the state results are packed and uploaded to the main edge regulating equipment, and the main edge regulating equipment carries out global integration on the state results uploaded by the auxiliary edge regulating equipment to form the overall cognition of the states of all cables to be accommodated in the whole cable accommodating area. When vibration information of a certain area is abnormal, the main edge regulating and controlling equipment can send an enhanced monitoring instruction to the auxiliary edge regulating and controlling equipment of the corresponding area, the frequency and the precision of the state evaluation of the related cable are required to be improved, and the auxiliary edge regulating and controlling equipment adjusts the self operation resource allocation according to the instruction, so that the state monitoring of the cable of the abnormal area is preferentially ensured. The layered regulation and control architecture can realize distributed real-time monitoring of the cable state, and ensure the stable operation of the whole system in the face of complex working conditions through global coordination of main edge regulation and control equipment.

Embodiment 2 the main edge regulating and controlling device adjusts the data acquisition frequency of the tension acquisition devices based on the vibration information acquired by the vibration sensing devices, and the specific process is as follows.

The tension acquisition equipment is operated according to a first preset acquisition frequency in an initial operation stage, the frequency is set according to conventional operation parameters of a cable storage area, the average winding speed, the environment vibration reference value and the like of a cable are covered, and resource waste caused by over-high frequency can be avoided while basic monitoring requirements are met. In this stage, the tension acquisition device continuously acquires tension information of the cable to be accommodated, including instantaneous values, variation amplitudes and the like of the tension, packages the information according to a fixed format, and periodically uploads the information to the corresponding secondary edge regulation device.

The plurality of vibration sensing devices are distributed at different positions of the cable storage area, including key points such as the vicinity of the winding driving device, the cable steering nodes, the edges of the storage area and the like, so as to form a vibration monitoring network covering the whole storage area. The vibration sensing devices capture vibration signals of the positions in real time, and the content of the signals contains information such as the frequency, the amplitude, the duration and the general direction of a vibration source. The vibration sensing equipment performs analog-to-digital conversion on the acquired vibration information, converts the vibration information into a digital signal and sends the digital signal to the main edge regulating equipment in a wired or wireless transmission mode.

And after receiving the vibration information uploaded by each vibration sensing device, the main edge regulating and controlling device classifies the vibration information. Firstly, binding the identification of each vibration sensing device with vibration information acquired by the vibration sensing device, and determining the monitoring position corresponding to each group of vibration data. And then, the main edge regulating and controlling equipment invokes a built-in vibration analysis program to analyze various parameters in the vibration information and compare the parameters with a preset vibration threshold value. The vibration threshold is determined according to factors such as structural characteristics of the cable storage area, equipment operation standards and the like, and comprises an upper amplitude limit corresponding to different frequency bands, a time threshold for continuous vibration and the like. When at least one parameter exceeds a corresponding preset threshold value in vibration information acquired by a certain vibration sensing device, the main edge regulating and controlling device marks the area where the vibration sensing device is positioned as a vibration abnormal subarea.

In the layout of the cable storage area, each winding driving device is responsible for winding work in a specific range, wherein the range is a corresponding winding sub-area, and a preset corresponding relation exists between each winding sub-area and the monitoring range of the plurality of vibration sensing devices. The main edge regulating and controlling equipment inquires a preset corresponding relation table according to the vibration sensing equipment identification corresponding to the vibration abnormal subarea, determines a winding subarea to which the vibration abnormal subarea belongs, and marks the winding subarea as an abnormal winding subarea. If the plurality of vibration abnormal subareas correspond to the same winding subarea, the main edge regulating and controlling equipment promotes the abnormal grade of the winding subarea so as to reflect the severity of the vibration abnormality of the winding subarea.

After the abnormal winding sub-area is determined, the main edge regulating and controlling equipment generates a data acquisition frequency adjusting instruction. The instruction comprises an identification of the abnormal winding sub-area, a tension acquisition equipment list to be adjusted and a new acquisition frequency parameter. The first preset acquisition frequency is generally set to be a lower value, so that the monitoring device is suitable for monitoring in a normal operation state of a cable, and can reduce equipment energy consumption and data transmission pressure while guaranteeing basic data acquisition. The second preset acquisition frequency is higher than the first preset acquisition frequency, the numerical value of the second preset acquisition frequency is determined according to the vibration abnormality degree of the abnormal winding sub-area, and the more serious the vibration abnormality is, the higher the second preset acquisition frequency is set to realize high-density acquisition of cable tension information.

The main edge regulating and controlling equipment sends an adjusting instruction to all tension collecting equipment in the abnormal winding area through a communication interface. After the tension acquisition equipment receives the instruction, the internal clock module and the data acquisition module are reconfigured, and the time interval of data acquisition is adjusted to be a value corresponding to the second preset acquisition frequency. After the adjustment is completed, the tension acquisition equipment acquires tension information of the cable to be accommodated according to the new acquisition frequency, and immediately uploads data to the corresponding auxiliary edge regulation equipment after the acquisition is completed. Meanwhile, the tension acquisition equipment feeds back a frequency adjustment result to the main edge regulation equipment, the main edge regulation equipment confirms the feedback result, and if the tension acquisition equipment which is not successfully adjusted exists, an adjustment instruction is sent again until all target equipment completes frequency adjustment.

After the vibration state of the abnormal winding sub-area is recovered to be normal, the main edge regulating and controlling equipment continuously monitors the vibration information of the area, when all parameters in the vibration information fall back to the range of a preset threshold value and the duration reaches the preset stable duration, the main edge regulating and controlling equipment judges that the abnormal state of the winding sub-area is relieved, and then a frequency recovery instruction is generated, and the data acquisition frequency of the tension acquisition equipment in the area is adjusted from the second preset acquisition frequency to the first preset acquisition frequency.

In the embodiment 3, the vibration abnormal subarea is determined based on the vibration information acquired by a plurality of vibration sensing devices, and links such as single-device data processing, multi-time-point analysis and region merging are needed.

Each vibration sensing device continuously works at preset sampling intervals, and the sampling intervals are set according to the environmental characteristics of the cable storage area, so that potential vibration changes can be captured. The mechanical vibration is converted into an electric signal by an induction element arranged in the vibration sensing device, and the electric signal is converted into a digital signal by an analog-to-digital converter after high-frequency noise is removed by a filter circuit. The digital signals contain original waveform data of vibration, each vibration sensing device binds the self identification with the digital signals to form a complete vibration information packet, and the complete vibration information packet is sent to the main edge regulation and control device through a wired transmission link.

After receiving the vibration information packet, the main edge regulating device firstly checks the data packet, checks the integrity and transmission error of the data, and if the error exists, sends a retransmission request to the corresponding vibration sensing device. After verification is passed, the main edge regulating and controlling equipment extracts original waveform data in the vibration information packet and calls a signal analysis module for processing. The signal analysis module converts the time domain waveform into a frequency domain spectrogram by adopting Fourier transformation, identifies main frequency components in the vibration signal, and calculates the vibration intensity value of each time point by combining time domain feature analysis. The vibration intensity value is obtained by comprehensively weighting parameters such as amplitude, acceleration peak value and energy density, and the intensity of vibration at the time point can be quantitatively reflected.

For each vibration sensing device, the main edge regulating device arranges vibration intensity values at a plurality of 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, and the analysis period covers enough sampling points to reflect the change trend of vibration. The main edge regulating and controlling device configures a vibration intensity threshold value and a duration time threshold value for each vibration sensing device, wherein the vibration intensity threshold value distinguishes the limit of normal vibration and abnormal vibration, and the duration time threshold value prescribes the duration time required for the vibration intensity to exceed the threshold value.

The main edge regulating device performs sliding window analysis on the vibration intensity time sequence, wherein the window size is one tenth of an analysis period, and each sliding step length is a sampling interval. And counting the times of the vibration intensity exceeding the vibration intensity threshold in each window, and judging that vibration abnormality exists in the time period corresponding to the window if the times are more than one third of the total sampling points in the window and the duration time of the state reaches the duration time threshold. When all three continuous windows are judged to be abnormal in vibration, the main edge regulating and controlling device marks the position where the vibration sensing device is located as a vibration abnormal point.

The cable housing area is divided into a plurality of grid cells, each corresponding 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 regulating and controlling equipment collects grid cells corresponding to all vibration abnormal points, and combines adjacent vibration abnormal grid cells to form a continuous area, namely a vibration abnormal subarea. If the grid cells corresponding to the vibration abnormal points are not adjacent, independent vibration abnormal subareas are formed respectively. Each vibration abnormal subarea comprises information such as a grid cell list covered by the vibration abnormal subarea, a related vibration sensing device identifier, abnormal starting time and the like, and the main edge regulating device stores the information into an abnormal area database and synchronously updates the information into other devices of the state regulating module, so that a basis is provided for the subsequent abnormal judgment of the winding subarea.

In determining the vibration anomaly sub-area, the primary edge regulation device may also rank the severity of the vibration anomaly in terms of amplitude, anomaly duration, and number of grid cells involved, including vibration intensity exceeding a threshold. The severity is classified into three classes of mild, moderate and severe, different classes corresponding to different processing priorities, the higher the severity class, the shorter the subsequent response speed requirement. The grading result is issued along with the information of the abnormal subareas of the vibration and is used for guiding the subsequent processing strategy of the winding subareas.

In the embodiment 4, the auxiliary edge regulating and controlling equipment firstly receives and pre-processes data when determining the real-time state of the cable to be received based on the tension information of the cable to be received acquired by the corresponding tension acquisition equipment. And each tension acquisition device continuously acquires displacement information, deformation information and friction information of the cable to be accommodated according to the set acquisition frequency, and sends the information with a time stamp to the corresponding auxiliary edge regulation device through a special communication link. After the secondary edge regulating and controlling equipment receives the data, checking the integrity of the data, and if the data frame is lost or checked to be wrong, immediately sending a supplementary transmission request to the corresponding tension acquisition equipment, so as to ensure that a continuous multi-time-point data sequence is acquired.

After the data is received, the secondary edge regulating and controlling equipment starts a data denoising process. Aiming at displacement information, the auxiliary edge regulating and controlling equipment extracts the peak value, the valley value, the mean value and the change slope of the auxiliary edge regulating and controlling equipment on the time domain to form a displacement time domain feature, meanwhile, the displacement information is decomposed into different frequency segments through wavelet transformation, the energy duty ratio of each frequency segment is calculated, and the displacement frequency domain feature is obtained. For deformation information, a similar processing mode is adopted, the accumulation amount, the change rate and the like of deformation quantity on a time axis are extracted to be used as deformation time domain characteristics, and main frequency components and corresponding amplitude values of the deformation information are obtained through Fourier transformation to be used as deformation frequency domain characteristics. The processing of the friction information focuses on the characteristics of the fluctuation range, the mutation times and the like of the friction coefficient and the spectrum distribution characteristics of the friction signals, and the characteristics are used as the friction frequency domain characteristics and the friction time domain characteristics.

The secondary edge regulation device invokes a pre-trained multi-modal denoising model that includes a feature fusion layer and a noise filter layer. The characteristic fusion layer performs dimension alignment and weight distribution on the displacement frequency domain characteristic, the displacement time domain characteristic, the deformation frequency domain characteristic, the deformation time domain characteristic, the friction frequency domain characteristic and the friction time domain characteristic to form a comprehensive characteristic vector, and the noise filter layer processes the comprehensive characteristic vector through a convolutional neural network, identifies and filters environmental interference signals and equipment noise components in the comprehensive characteristic vector, and outputs denoised displacement information, deformation information and friction information.

Based on the denoised information, the secondary edge regulating and controlling equipment calculates a risk value of the cable to be accommodated, wherein the calculating mode is as follows: Wherein, the Representing the value of the risk,Representing a displacement anomaly coefficient, and determining the deviation degree of the actual displacement and the rated displacement range; representing deformation influence coefficients, and calculating based on the ratio of the deformation quantity to the maximum allowable deformation quantity of the cable; representing a friction risk coefficient, and determining according to the amplitude of the friction coefficient exceeding a safety threshold value; The weight coefficients of displacement, deformation and friction are preset according to the cable type and the use scene, and the values of the weight coefficients are respectively 。

When (when)When the risk value is larger than a preset risk value threshold value, the auxiliary edge regulating and controlling equipment sends a position inquiry signal to the winding guide component on the cable to be received. After the signal is received by the winding guide component, the real-time coordinate of the winding guide component is obtained through the built-in positioning module, and a position feedback signal is generated and returned to the auxiliary edge regulating and controlling equipment. The auxiliary edge regulating and controlling equipment combines the position feedback signals to determine the real-time position of the cable to be accommodated, and then analyzes the stress state, the abrasion condition and the movement trend of the cable at the current position by combining the de-noised displacement, deformation and friction information, and finally determines the real-time state.

The parameter scheduling equipment in the state regulation and control module is connected with all the tension acquisition equipment and the edge regulation and control equipment through an industrial Ethernet, and the data acquisition frequency of each tension acquisition equipment is acquired in real time. When a certain winding sub-area is marked as an abnormal winding sub-area, the parameter scheduling device determines the cable to be received corresponding to the winding guide component in the area as an abnormal cable to be received, the tension acquisition device corresponding to the abnormal cable to be received is the abnormal tension acquisition device, and the auxiliary edge regulation device originally corresponding to the tension acquisition device is listed as the auxiliary edge regulation device to be scheduled. The parameter scheduling device inquires the current load capacity of each pair of edge regulating devices, and the load capacity is comprehensively estimated through the number of tension acquisition devices which are being processed and the data processing time delay. According to the number of the abnormal tension acquisition devices and the load condition of the auxiliary edge regulation devices to be scheduled, the parameter scheduling device redistributes the corresponding relation, namely, if the load quantity of the auxiliary edge regulation devices to be scheduled is lower than a threshold value, the corresponding relation between the auxiliary edge regulation devices and part of the abnormal tension acquisition devices is kept, and if the load quantity is too high, the part of the abnormal tension acquisition devices are distributed to other auxiliary edge regulation devices with lower loads, or standby auxiliary edge regulation devices are temporarily started to bear the monitoring task, so that each abnormal tension acquisition device is ensured to have the corresponding auxiliary edge regulation device for data processing. After the redistribution is completed, the parameter scheduling device updates the corresponding relation table of the edge regulating device and the tension collecting device, and synchronizes to the main edge regulating device and the related auxiliary edge regulating device, so that the dynamic allocation of the monitoring resources is realized.

In embodiment 5, when the protection execution module triggers the protection execution operation of the cable storage area in real time, the real-time state of the cable to be received uploaded by the state regulation module is received through the internal data interface. The real-time state comprises various information, such as the current tension value of the cable, which is directly measured by a tension sensing component in the tension acquisition device, the displacement change rate of the cable in unit time is calculated by data acquired by a displacement sensor, the deformation degree of the cable due to the tension is determined by the monitoring result of the deformation sensor, the friction coefficient of the cable when the cable is in contact with the winding guide assembly, the detection data from the friction sensor, and the specific position coordinate of the cable in the cable storage area are analyzed by a position feedback signal uploaded by the winding guide assembly. The information is arranged according to the time stamp sequence to form a continuous state data stream, and the protection execution module analyzes the data stream in real time to extract key parameters related to cable abnormality judgment.

The protection execution module internally stores a preset abnormal grading standard, and the standard is formulated according to the physical characteristics and the use requirements of the cable. For example, for cables of different materials, the maximum tension that the cables can bear is different, the corresponding tension abnormality threshold is different, if the displacement change rate of the cables exceeds a certain value, the displacement change rate may mean that the cable is jammed or overspeed in the winding process, if the deformation degree exceeds the elastic range of the cable, permanent damage may be caused, and if the friction coefficient is too high, local overheating may be caused. The abnormal grades are divided into a plurality of grades, each grade corresponds to a range of a group of key parameters, for example, the first grade abnormality can correspond to the tension slightly higher than the normal range but not exceeding a safety threshold, the displacement change rate is stable, the deformation and the friction coefficient are in a normal range, the second grade abnormality can correspond to the tension close to the safety threshold, the displacement change rate fluctuates, the deformation degree slightly exceeds the elastic range, the third grade abnormality corresponds to the tension exceeding the safety threshold, the displacement change rate rises sharply, the deformation is obvious, and the friction coefficient greatly exceeds the standard. The protection execution module compares the key parameters in the real-time state with the abnormal grade classification standard to determine the abnormal grade to which the cable to be accommodated belongs.

The preset protection action library is stored in a local memory of the protection execution module, and the library contains protection execution instructions corresponding to each abnormal level. For example, for a first level anomaly, the protection execution instruction may be "reduce the winding rate by 10%", alleviate tension by slowing the winding speed, for a second level anomaly, the instruction may be "reduce the winding rate by 30% and continuously monitor", further reduce tension and enhance status tracking, and for a third level anomaly, the instruction may be "immediately execute emergency braking", stop winding action to avoid cable breakage or damage. Each protection execution instruction also contains execution details, such as a specific value of the winding rate adjustment, a triggering mode of emergency braking, a state feedback requirement after execution, and the like. The protection execution module retrieves corresponding protection execution instructions from a preset protection action library according to the determined abnormal level, and performs integrity check on the instructions, so that the instruction is ensured to be correct in format and contain necessary execution parameters.

The protection execution module sends a protection execution instruction to the corresponding furling driving device through the control bus, wherein the instruction comprises the identification of the target furling driving device, and the instruction is ensured to be accurately sent. After receiving the instruction, the furling driving device decodes the instruction and extracts the operation type and parameters. If the command is the winding speed adjustment, a motor controller in the winding driving device adjusts the power supply frequency or voltage of the motor according to the parameters, changes the motor rotating speed, and then adjusts the winding speed of the cable, the whole adjustment process is realized through closed loop feedback, and the motor controller acquires the current rotating speed in real time and compares the current rotating speed with the target rotating speed until the rotating speed is stabilized within the range required by the command. If the command is emergency braking, a braking unit in the winding driving device is immediately started, the winding mechanism is stopped by a mechanical braking or electromagnetic braking mode, and meanwhile, the power supply of the motor is cut off, so that misoperation is prevented.

In the process of performing the protection execution operation, the protection execution module continuously receives the execution state information returned by the winding driving device, such as the current winding speed, whether the braking is effective, and the like, so as to confirm whether the operation is performed as expected. If an abnormality occurs in the execution process, for example, the winding rate is not adjusted according to the instruction or the braking is invalid, the protection execution module can resend the instruction or trigger a higher-level protection operation. After the operation is finished, 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, and provides a reference for subsequent system maintenance.
