DETAILED DESCRIPTION

[0026] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0029] Embodiment 1, reference Figs. 1-4 For the first embodiment of the present application, the embodiment provides a combined adaptive electromagnetic hoisting device for ships, comprising: A rectangular frame 1, which is provided with a moving guide rail interface at the top, a first rectangular plate 3 arranged at the bottom of the rectangular frame 1, an iron chain 7 arranged on one side of the first rectangular plate 3, and a first electromagnet 5 fixedly connected to the end of the iron chain 7; A second rectangular plate 4 arranged on the top of the rectangular frame 1, and a second electromagnet 6 suspended on both sides of the second rectangular plate 4 through the iron chain 7; An infrared sensor 14 and a stress / displacement sensor 15 integrated on the second electromagnet 6; A central control module for receiving sensor data and controlling the angle adjustment of the second electromagnet 6; A current control unit 10 for controlling the on-off of the first electromagnet 5 and the second electromagnet 6, and an up-down guide rail system 2 for guiding the translational motion of the first rectangular plate 3 and the second rectangular plate 4; The iron chain 7 is fixedly installed on the surface of the first rectangular plate 3 and the second rectangular plate 4 through the first fixing bolt 11; Further, the up-down guide rail system 2 includes a translational driving and positioning mechanism 17, which further includes a ball screw transmission mechanism driven by a servo motor; It should be noted that the rotational motion of the ball screw is accurately controlled by the servo motor, which is converted into linear displacement, thereby realizing high-precision translation and positioning of the first rectangular plate 3 and the second rectangular plate 4. Compared with the traditional hydraulic or pneumatic method, the ball screw has the advantages of fast response speed, high repeat positioning accuracy and stable operation, which can effectively improve the operation flexibility and control accuracy of the hoisting device in complex space environment, and is suitable for high-precision ship manufacturing and maintenance scenes.

[0030] Further, the second electromagnet 6 is connected by a hinge to achieve angle adjustment, the infrared sensor 14 is a line array scanning infrared detector, the first electromagnet 5 is provided with a first chain hanging interface 8 at the connection with the iron chain 7, the second electromagnet 6 is provided with a second chain hanging interface 12 at the connection with the iron chain 7, and the surfaces of the first electromagnet 5 and the second electromagnet 6 are provided with electromagnet shells 9; It should be noted that the above structure design enables the second electromagnet 6 to automatically adjust the angle according to the surface curvature of the steel plate during the adsorption process, thereby improving the fitting degree and adsorption stability. The line array scanning infrared sensor 14 can scan the profile of the steel plate surface in real time, providing high-resolution spatial data for AI algorithm analysis. The first chain hanging interface 8 and the second chain hanging interface 12 adopt a modular connection design, which facilitates quick replacement of electromagnet components of different specifications, enhances the applicability of the equipment, and the electromagnet shells 9 play a role in dustproofing, waterproofing, and protecting the internal coils and circuits, thereby improving the overall durability and safety.

[0031] Further, the current control unit 10 is used to independently control the start and stop of the first electromagnet 5 and the second electromagnet 6, supporting three control modes of global adsorption, regional adsorption, and gradual release; It should be noted that this design allows flexible selection of adsorption modes according to different steel plate shapes, weight distribution, and work requirements. Global adsorption is suitable for large-area flat steel plates to ensure maximum adsorption force. Regional adsorption can apply adsorption force to local areas and is suitable for special-shaped or thin plate materials. The gradual release mode can be powered off in stages during unloading, avoiding the impact or sliding risk caused by instantaneous demagnetization. The multi-mode control strategy improves the safety, adaptability, and energy utilization efficiency of the lifting process.

[0032] Further, a buffer damping component is arranged between the second electromagnet 6 and the second rectangular plate 4 for relieving impact load during steel plate adsorption or release; It should be noted that the buffer damping component is usually composed of a spring-hydraulic composite structure or a rubber shock pad, which absorbs part of the kinetic energy at the moment of electromagnet contact with the steel plate, reducing mechanical stress and vibration transmission caused by rigid collision. This not only prolongs the service life of the equipment, but also reduces the risk of steel plate deviation or falling due to sudden stress changes during lifting, especially for high-frequency and large-tonnage lifting tasks, thereby improving the stability of the whole machine operation and the safety of the operators.

[0033] The embodiment also provides a marine combined adaptive electromagnetic lifting device control system, comprising: a sensor data acquisition unit for receiving data of the infrared sensor 14 and the stress / displacement sensor 15; The electromagnetic module unit 13 arranged inside the first electromagnet 5 and the second electromagnet 6 contains a coil, a driving circuit and an adjustable adsorption structure; An AI adaptive algorithm module for analyzing sensor data and generating control instructions; A current control unit 10 for performing on-off control of the first electromagnet 5 and the second electromagnet 6; A translation control unit for controlling the movement of the translation drive and positioning mechanism 17; The infrared sensor 14 and the stress / displacement sensor 15 are arranged with the second fixing bolt 16 at the connection of the first electromagnet 5 and the second electromagnet 6; Further, the sensor data acquisition unit is used to read the data of the infrared sensor 14 and the stress / displacement sensor 15 integrated on the second electromagnet 6, to obtain the deformation profile and stress condition of the steel plate surface; The current control unit 10 is used to monitor the working state of the first electromagnet 5 and the second electromagnet 6, and record the adsorption current intensity and working time parameters of each magnet; The data is uploaded to the remote server through the Internet of Things communication module to form a historical database; The data collected from the sensor and the current control unit is screened to remove outliers and noise interference; The preprocessed data is normalized, and the expression is: ; Wherein, represents the original data, represents the average value, represents the standard deviation; The neural network structure is designed, including the input layer, the hidden layer and the output layer; The input layer receives the preprocessed sensor data, and the output layer predicts the optimal magnet activation sequence and angle adjustment path; The neural network model is trained using the back propagation algorithm BP, and the weight matrix and bias term are adjusted to minimize the value of the loss function; Wherein, the loss function The expression is: ; Wherein, is the true value, is the predicted value; The data set is divided into a training set and a validation set, the training set is used for model training, and the model performance is tested on the validation set; Based on the historical lifting data, the reinforcement learning mechanism is used to further optimize the model decision strategy; By simulating different lifting scenarios, the reward value under each strategy is calculated, and the strategy that maximizes the cumulative reward is selected as the final strategy; When a new lifting task begins, the central control module calls the optimized neural network model, inputs the current state information of the steel plate, and obtains the optimal magnet activation sequence and angle adjustment path.

[0034] The translation control unit and the translation drive and positioning mechanism 17 are used to adjust the positions of the first and second rectangular plates 3 and 4 according to the model output results, and the current control unit 10 is used to control the start and stop of each group of electromagnets.

[0036] Furthermore, the control system includes an Internet of Things communication module that supports breakpoint resuming and remote maintenance functions, can upload device status and fault logs in real time, and the specific steps are as follows: The sensor data acquisition unit collects the working status of the first and second electromagnets 5 and 6, the data of the infrared sensor 14 and the stress / displacement sensor 15, and the state information of the current control unit 10; The data is packaged into data packets according to a predefined format, where each data packet contains a device identifier, a timestamp, a data type, and specific values; The Internet of Things communication module is used to send the packaged data packets to the remote monitoring platform in real time, and the built-in breakpoint resuming mechanism is used to automatically save the data packets that have not been successfully uploaded when network interruption or other failures occur, and continue uploading after the network is restored; After each successful upload of a data packet, update the local record and mark it as uploaded to avoid repeated uploading of the same data; When an abnormal situation or device failure is detected, a detailed fault report is generated using the central control module, including the time, location, possible cause, and impact range of the fault; The generated fault report is also packaged into a data packet of a specific format and uploaded to the remote monitoring platform in a timely manner through the Internet of Things communication module. The remote access interface provided by the Internet of Things communication module allows technicians to diagnose and maintain the device through the Internet; It should be noted that the introduction of the Internet of Things communication module enables the system to have remote monitoring and operation and maintenance capabilities. Even in the case of network interruption, the breakpoint resume mechanism can ensure data integrity, and all device status information, fault logs, and operation records can be uploaded to the remote server in real time, facilitating centralized management and big data analysis. At the same time, the remote access interface supports online debugging, firmware upgrading, and fault troubleshooting, significantly reducing on-site maintenance costs and time overhead, and is particularly suitable for special operating environments such as offshore platforms and ocean-going ships that are difficult to maintain frequently.

[0037] The embodiment also provides a computer device suitable for the case of the marine combined adaptive electromagnetic hoisting device, including a memory and a processor; the memory is used to store computer executable instructions, and the processor is used to execute the computer executable instructions to realize the marine combined adaptive electromagnetic hoisting device proposed in the above embodiment.
