Description

Technical Field

[0001] This application relates to the field of equipment selection technology, and in particular to a method, system, equipment and storage medium for selecting a construction hoist system. Background Technology

[0002] Construction hoists are a common type of vertical lifting and lowering engineering equipment used in the lifting industry. In order to ensure that construction hoists are stable and reliable and can meet the application requirements of different working conditions, it is necessary to select the appropriate construction hoist system.

[0003] Currently, the method for selecting electromechanical control equipment is based on the user's basic needs, combined with rough theoretical estimations or empirical formulas to calculate the equipment model that meets the user's requirements. Then, the mechanism selected based on the equipment model is configured in the construction hoist system. The equipment model is repeatedly adjusted according to the actual performance of the construction hoist system until the mechanism corresponding to the equipment model meets the actual application requirements. However, when selecting a mechanism that needs to meet high acceleration, high load and other working conditions, it is necessary to leave a margin in the basic performance of the mechanism. Moreover, selecting the equipment model by rough theoretical estimations or empirical formulas is prone to errors in the selection of the construction hoist system, and increases costs, resulting in low efficiency in the selection of the construction hoist system. Summary of the Invention

[0004] The main objective of this application is to provide a method, system, equipment, and storage medium for selecting a construction hoist system, aiming to solve the technical problem of low efficiency in selecting a construction hoist system due to the prior art of configuring the mechanism selected according to the equipment model in the construction hoist system and repeatedly adjusting the equipment model according to the actual performance of the construction hoist system.

[0005] To achieve the above objectives, this application provides a method for selecting a construction hoist system, the method comprising:

[0006] Upon receiving a configuration selection instruction, the selection requirements information for the construction hoist system and the type information of the construction hoist are obtained from the configuration selection instruction.

[0007] Based on a preset set of calibration conditions, select a mechanical simulation model that matches the type information.

[0008] If the performance indicators of the initial digital prototype coupled with electromechanical control are optimal based on the mechanical simulation model, then a target simulation model that meets the selection requirements information is selected based on the mechanical simulation model and the preset working conditions.

[0009] The selection of the electromechanical control equipment corresponding to the target simulation model is taken as the target selection scheme for the construction hoist system.

[0010] Optionally, the step of selecting a target simulation model that meets the selection requirements based on the mechanical simulation model and preset working conditions includes:

[0011] Based on the preset working conditions, an initial simulation model of the electromechanical control equipment is selected, and the initial simulation model is coupled with the mechanical simulation model to form a debugging digital prototype.

[0012] Under the preset operating conditions, the debug digital prototype is run to obtain virtual operating results;

[0013] If the virtual operation results do not meet the selection requirements of the selection requirements information, then based on the initial simulation model, an optimized simulation model is iteratively selected, and the optimized simulation model replaces the initial simulation model in the debug digital prototype.

[0014] Under the preset operating conditions, the debugging digital prototype is run again to obtain iterative running results until the iterative running results meet the selection requirements information, and the target simulation model is obtained.

[0015] Optionally, before the step of determining that the performance index of the initial digital prototype based on the combination of the mechanical simulation model and the pre-selected calibration model is optimal, the method further includes:

[0016] Under the calibration condition set, the initial digital prototype is run to obtain the initial performance indicators of the initial digital prototype;

[0017] Based on a preset evaluation function, the performance indicators of the initial digital prototype are evaluated to determine whether they are optimal.

[0018] The evaluation function may be a function of a single performance index or a function of multiple comprehensive performance indexes.

[0019] Optionally, the step of evaluating whether the performance indicators of the initial digital prototype are optimal based on a preset evaluation function includes:

[0020] If, based on the evaluation function, it is determined that the performance index of the initial digital prototype is not optimal, then, based on a preset optimization algorithm, the information data after optimizing the mechanical simulation model is determined.

[0021] Based on the information data, an optimized mechanical model is selected, and the optimized simulation model replaces the original mechanical simulation model.

[0022] Under the calibration condition set, the initial digital prototype is run again to obtain iterative performance indicators until the iterative performance indicators are optimal.

[0023] Optionally, the step of evaluating whether the performance indicators of the initial digital prototype are optimal based on a preset evaluation function includes one of the following:

[0024] If, based on the evaluation function, a single performance index of the initial digital prototype is determined to be optimal, then the performance index of the initial digital prototype is determined to be optimal.

[0025] If, based on the evaluation function, the comprehensive index of multiple performance parameters of the initial digital prototype is determined to be optimal, then the performance index of the initial digital prototype is determined to be optimal.

[0026] Optionally, before the step of selecting a mechanical simulation model from the digital prototype system that conforms to the type information and whose performance is optimal, based on a preset calibration condition set, the following steps are included:

[0027] Based on the mechanical structure of the construction hoist system, determine the mechanical model and mechanism model of the virtual mechanical structure in the digital prototype;

[0028] Based on the control information of the construction hoist system, determine the control model of the virtual control in the digital prototype;

[0029] Based on the power information of the construction hoist system, the electromechanical coupling system model of the virtual power in the digital prototype is determined;

[0030] The simulation model is generated based on the mechanical model, the mechanistic model, the control model, and the electromechanical coupling system model.

[0031] Optionally, the key components of the electromechanical control coupled system model form a complete virtual equipment and simulation system, wherein the simulation system is a mapped twin system of the construction hoist system.

[0032] This application also provides a digital prototyping system, the digital prototyping system comprising:

[0033] The control model includes a system control model and a motor drive model. The system control model is used to simulate the controller of the construction hoist system and determine the performance of the controller. The motor drive model is used to simulate the motor drive controller of the construction hoist system and determine the performance indicators of the motor driver.

[0034] The electromechanical control coupled system model includes a hoist equipment model, a motor model, and a mechanical transmission model. The hoist equipment model is used to simulate the hoist equipment in the construction hoist system, the motor model is used to simulate the motor equipment in the construction hoist system, the mechanical transmission model is used to simulate the mechanical transmission group in the construction hoist system, and the electromechanical control coupled system is used to simulate all the control logic, control variables, operating principles, operating states, electrical information, and mechanical operating information of the construction hoist system.

[0035] The mechanical and mechanistic models of the key components of the system are used to visualize the connection relationships, internal mechanisms, and interaction relationships of the equipment in the construction hoist system.

[0036] This application also provides a selection device for a construction hoist system, the selection device for the construction hoist system comprising: a memory, a processor, and a program for the selection method of the construction hoist system stored in the memory and executable on the processor, wherein when the program for the selection method of the construction hoist system is executed by the processor, the steps of the selection method of the construction hoist system as described above can be implemented.

When the program for selecting a construction hoist system is executed by a processor, it implements the steps of the above-described method for selecting a construction hoist system.

[0038] This application provides a selection method, system, equipment, and storage medium for a construction hoist system. Compared to the prior art, which involves selecting mechanisms based on equipment models and repeatedly adjusting equipment models based on the actual performance of the construction hoist system, resulting in low selection efficiency, this application, upon receiving a configuration selection instruction, obtains the selection requirements and type information of the construction hoist system from the instruction; selects a mechanical simulation model that conforms to the type information based on a preset calibration condition set; if the performance indicators of the initial digital prototype coupled with electromechanical control are optimal based on the mechanical simulation model, then selects a target simulation model that conforms to the selection requirements based on the mechanical simulation model and the preset conditions; and uses the selection of the electromechanical control equipment corresponding to the target simulation model as the target selection scheme for the construction hoist system. In this application, the selection requirements and type information of the construction hoist system are obtained from the configuration selection instructions. Based on the preset calibration conditions, a mechanical simulation model that meets the type information is selected, and the electromechanical control of the mechanical simulation model is coupled into an initial digital prototype. The performance index of the initial digital prototype is judged. If the performance index is optimal, a target simulation model that meets the selection requirements is selected based on the mechanical simulation model and the preset conditions. The selection of the electromechanical control equipment corresponding to the target simulation model is used as the target selection scheme for the construction hoist system. That is, in this application, the operation of the construction hoist system under different working conditions is simulated by the digital prototype, which replaces the repeated adjustment of equipment models based on the actual performance of the construction hoist system, thereby improving the selection efficiency of the construction hoist system.

[0047] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0048] This application provides a method for selecting a construction hoist system. In the first embodiment of this method, referring to... Figure 1 The selection method for the construction hoist system includes:

[0049] Step S10: Upon receiving the configuration selection instruction, obtain the selection requirements information of the construction hoist system and the type information of the construction hoist from the configuration selection instruction;

[0050] Step S20: Based on the preset calibration condition set, select a mechanical simulation model that matches the type information;

[0051] Step S30: If the performance index of the initial digital prototype coupled with electromechanical control is optimal based on the mechanical simulation model, then select a target simulation model that meets the selection requirements based on the mechanical simulation model and the preset working conditions.

[0052] Step S40: The selection of the electromechanical control equipment corresponding to the target simulation model is taken as the target selection of the construction hoist system.

[0053] This embodiment aims to improve the efficiency of selecting construction hoist systems by simulating the operation of construction hoist systems under different working conditions through digital prototypes.

[0054] In this embodiment, it should be noted that the selection method for the construction hoist system can be applied to the selection device for the construction hoist system. The selection device for the construction hoist system belongs to the selection equipment for the construction hoist system, which belongs to the selection system for the construction hoist system, that is, the digital prototype system.

[0055] Reference Figure 4It should be noted that a construction hoist system includes at least a control system, a motor, a transmission module, and mechanical components. The digital prototype system includes a control model, an electromechanical-control coupling system model, and mechanical and mechanistic models of key system components. The mechanical model specifically refers to the mechanical models of the key components of the construction hoist system.

[0056] Among them, the control model can simulate the control model of the construction hoist system in order to simulate the control of the construction hoist system, and it can also simulate the motor drive control model in order to simulate the control of the motor.

[0057] Among them, the electromechanical control coupling system model can simulate various types of construction hoist equipment models, various types of motor models, and various types of mechanical transmission models, so as to simulate the construction hoist system.

[0058] Among them, the mechanical model and mechanism model of the key components of the system can simulate the structure and connection of each component in the construction hoist system.

[0059] It should be noted that by simulating the construction hoist system through a digital prototype system and selecting the appropriate model within the digital prototype system, the need for trial operation and repeated adjustments to the electromechanical control equipment models in the actual construction hoist system is avoided, thereby improving the efficiency of selecting the construction hoist system.

[0060] Among them, electromechanical control equipment may include controllers, motors, transmission modules, etc., without specific limitations.

[0061] In this embodiment, the digital prototype system can completely simulate the actual working state of the construction hoist system. That is, by simulating the working state of the construction hoist system through the digital prototype system, and selecting the corresponding target simulation model according to the working state, and then determining the model of the electromechanical control equipment corresponding to the target simulation model, the selected model of electromechanical control equipment can be more in line with the actual construction hoist system.

[0062] In this embodiment, refer to Figure 2 , Figure 2 This is a schematic diagram of the selection process for the construction hoist system in this application.

[0063] The specific steps are as follows:

[0064] Step S10: Upon receiving the configuration selection instruction, obtain the selection requirements information of the construction hoist system and the type information of the construction hoist from the configuration selection instruction;

[0065] The configuration selection command can be used to select the model of the motor, the model of the controller, and the data of the transmission module based on the mechanical components in the construction hoist system, so that the construction hoist system can meet the current working conditions.

[0066] Among them, the selection requirements information can include information such as the motor power, transmission method, and operating conditions of the construction hoist system that the user expects to require.

[0067] The type of construction hoist can be a fixed hoist, a hydraulic hoist, a telescopic boom hoist, etc., without any specific limitation.

[0068] In this embodiment, when a configuration selection instruction for a construction hoist system is received, the selection requirement information of the construction hoist system is extracted from the configuration selection instruction. That is, the information such as motor information, transmission information, and working condition information required by the user is extracted from the configuration selection instruction. The type information of the construction hoist is also extracted from the configuration selection instruction so that the digital prototype system can select the simulation model corresponding to the construction hoist system according to the selection requirement information and the type information.

[0069] Step S20: Based on the preset calibration condition set, select a mechanical simulation model that matches the type information;

[0070] The calibration condition set can be a collection of different conditions preset by the user, used to calibrate the mechanical simulation model in the digital prototype.

[0071] Among them, the mechanical simulation model is the simulation model of the elevator in the digital prototype.

[0072] In this embodiment, firstly, a mechanical simulation model of the construction hoist is selected from the digital prototype system based on the type information. Then, a calibration model that meets the selection requirements and calibration condition set is selected from the digital prototype system. The mechanical simulation model and the calibration model are coupled and combined to form an initial digital prototype. The initial digital prototype is then virtually run under calibration conditions, and its performance is determined based on its operating status to determine if it is in its optimal state. The transfer model includes at least a mechanical transmission model, a motor model, and a controller model.

[0073] In this embodiment, a mechanical simulation model of the construction hoist can be selected from the digital prototype system based on a preset calibration load set, and a calibration model that meets the selection requirements and calibration load set can also be selected from the digital prototype system. The optimal performance state of the digital prototype is determined based on the calibration load set or calibration condition set.

[0074] It should be noted that the type information can also include key components or key mechanical parts of the construction hoist. The data prototype system can also generate corresponding hoist models based on the key components or key mechanical parts in the type information. The hoist model can be obtained by first selecting a mechanical simulation model that matches the key components or key mechanical parts from the digital prototype system, and then adjusting the size, connection relationship, position, etc. of the mechanical simulation model according to the key components or key mechanical parts to obtain a mechanical simulation model that matches the type information. This improves the accuracy of the simulation of the digital prototype system. By replacing the selection of the construction hoist with the selection of a mechanical simulation model that accurately matches the type information, the final target selection can be more in line with the requirements information, that is, more in line with the preset working conditions or target load, while saving selection time.

[0075] In this embodiment, a mechanical simulation model, a motor model, a controller model, and a mechanical transmission model are first selected from the digital prototype system. An initial digital prototype is then formed by coupling these models. Under a calibration set of operating conditions, the initial digital prototype is simulated and run. Based on the simulation operation status or simulation operation data of the initial digital prototype, it is determined whether the performance indicators of the digital prototype are optimal. This determines whether the mechanical simulation model is the most suitable simulation model for the construction hoist, so that the digital prototype can accurately imitate the working state, operating principle, control logic, and other operating information of the construction hoist.

[0076] It should be noted that the motor model, controller model, and initial mechanical transmission model were randomly selected based on the calibration conditions or calibration load. In other words, the performance of the motor model, controller model, and initial mechanical transmission model after matching them only needs to meet the calibration conditions or calibration load.

[0077] Step S30: If the performance index of the initial digital prototype coupled with electromechanical control is optimal based on the mechanical simulation model, then select a target simulation model that meets the selection requirements based on the mechanical simulation model and the preset working conditions.

[0078] In this embodiment, if the performance indicators of the initial digital prototype are optimal, then a motor model, a controller model, and a transmission model are selected from the digital prototype system according to preset operating conditions. The motor model, controller model, transmission model, and mechanical simulation model are coupled to form a debugging digital prototype. The debugging digital prototype is then virtually run under preset operating conditions to determine the virtual running results. Based on the virtual running results, the models of the motor model, controller model, and transmission model are adjusted to obtain a target simulation model that meets the requirements. That is, a target motor model, target controller model, and target transmission model that meet the selection requirements are obtained, so that the performance indicators of the debugging digital prototype are optimal.

[0079] In this embodiment, before selecting the target simulation model, it is necessary to determine that the performance indicators of the initial digital prototype coupled with the mechanical simulation model and the electromechanical control are optimal, so as to reduce the error between the mechanical simulation model and the hoist and make the debugging digital prototype closer to the construction hoist system.

[0080] It should be noted that the debugging digital prototype can also be regarded as the initial digital prototype after the selection of motor model, controller model and transmission model has been changed.

[0081] Specifically, the step of selecting a target simulation model that meets the selection requirements based on the mechanical simulation model and the preset working conditions includes:

[0082] Step S31: Based on the preset working conditions, select the initial simulation model of the electromechanical control equipment, and couple the initial simulation model with the mechanical simulation model to form a debugging digital prototype;

[0083] The initial simulation model includes the motor model, controller model, and transmission model selected for the first time after the mechanical simulation model is determined.

[0084] Step S32: Under the preset operating conditions, run the debug digital prototype to obtain virtual operation results;

[0085] The virtual operation results include the performance indicators of the motor model, the control model, and the transmission model after the debugged digital prototype has been running virtually under preset operating conditions.

[0086] In this embodiment, the mechanical simulation model of the construction hoist is first determined from the digital prototype system based on type information. Then, according to the calibration condition set, the calibration motor model, calibration controller model, and calibration transmission model are determined for calibrating the mechanical simulation model. These models are then coupled and combined to form an initial digital prototype. The digital prototype is run under calibration conditions to obtain virtual calibration results. Based on these results, it is determined whether the initial digital prototype's performance is optimal. If the initial digital prototype's performance is optimal, the selected motor model, controller model, and mechanical transmission model are changed to obtain a debug digital prototype. This debug digital prototype is then virtually run under preset conditions, and the virtual running results are obtained. In other words, the performance indicators of the initial simulation model are obtained by virtually running the debug digital prototype under preset conditions.

[0087] Step S33: If the virtual running result does not meet the selection requirements of the selection requirement information, then based on the initial simulation model, an optimized simulation model is iteratively selected, and the optimized simulation model replaces the initial simulation model in the debug digital prototype.

[0088] In this embodiment, if the virtual operation results do not meet the selection requirements of the selection information, an optimized simulation model that is closer to the selection requirements is iteratively selected based on the model of the initial simulation model, and the optimized simulation model replaces the initial simulation model in the debugging digital prototype.

[0089] For example, if the performance index of the debug digital prototype configured with the initial simulation model is determined by the virtual operation results to be less than the selection requirements of the selection information, then the first simulation model that can improve the performance of the debug digital prototype is selected and the first simulation model replaces the initial simulation model. If the performance index of the debug digital prototype after replacing the first simulation model is higher than the selection requirements of the requirements information, then a second simulation model corresponding to a model is selected between the model corresponding to the initial simulation model and the model corresponding to the first simulation model, until an optimized simulation model is selected.

[0090] Step S34: Under the preset operating conditions, run the debugging digital prototype again to obtain iterative running results until the iterative running results meet the selection requirements information, and obtain the target simulation model;

[0091] In this embodiment, after the initial digital prototype reaches its optimal performance, the models of the initial motor model, initial controller model, and initial mechanical transmission model are selected according to preset operating conditions. The mechanical simulation model is then coupled with the initial motor model, initial controller model, and initial mechanical transmission model to form a debug digital prototype. If the performance of the debug digital prototype under preset operating conditions cannot meet the selection requirements of the selection information, the initial motor model, initial controller model, and initial mechanical transmission model are adjusted according to the obtained virtual operation results until the performance of the debug digital prototype under preset operating conditions meets the selection requirements of the selection information, thus obtaining the target simulation model.

[0092] It should be noted that the adjustments to the initial motor model, initial controller model, and initial mechanical transmission model can be iteratively optimized based on the virtual operation results. That is, if the virtual adjustment result indicates that the power of the required motor model is too small, the model type of the required motor model is first determined. Then, a motor model with a larger power than the required motor model is selected in the digital prototype system, and the optimized motor model corresponding to the optimized motor model is applied to the digital prototype for virtual operation to obtain the virtual adjustment result. If the virtual adjustment result obtained under the configuration of the optimized motor model indicates that the power of the optimized motor model is still too small, the adjustment continues until the power of the optimized motor model can meet the preset working conditions. The adjustment method for the required controller model and the required initial mechanical transmission model is the same as the adjustment method for the required motor model.

[0093] It should be noted that adjustments to the initial motor model, initial controller model, and initial mechanical transmission model can be performed simultaneously. That is, optimization adjustments are made based on the overall performance of the initial motor model, initial controller model, and initial mechanical transmission model to avoid performance waste. Alternatively, two of them can be selected and the third debugged, or one can be selected and the other two debugged.

[0094] Specifically, before the step of determining that the performance index of the initial digital prototype formed by combining the mechanical simulation model and the pre-selected calibration model is optimal, the method further includes:

[0095] Step A10: Under the calibration condition set, run the initial digital prototype to obtain the initial performance index of the initial digital prototype;

[0096] Step A20: Based on a preset evaluation function, evaluate whether the performance indicators of the initial digital prototype are optimal;

[0097] The evaluation function may be a function of a single performance index or a function of multiple comprehensive performance indexes.

[0098] In this embodiment, the evaluation function can be a function of a single performance index or a combination of multiple performance indices, or it can be a function of the deviation of a single index or a combination of multiple indices from the construction hoist system.

[0099] In this embodiment, an evaluation function is used to determine whether the performance indicators of the initial digital prototype are optimal, so as to unify the judgment criteria and thus more scientifically determine the matching degree between the mechanical simulation model and the elevator.

[0100] Specifically, the step of evaluating whether the performance indicators of the initial digital prototype are optimal based on a preset evaluation function includes the following:

[0101] Step B10: If, based on the evaluation function, a single performance index of the initial digital prototype is determined to be optimal, then the performance index of the initial digital prototype is determined to be optimal.

[0102] Step B20: If, based on the evaluation function, the comprehensive index of multiple performance parameters of the initial digital prototype is determined to be optimal, then the performance index of the initial digital prototype is determined to be optimal.

[0103] In this embodiment, the standard for determining the optimal performance index of the initial digital prototype can also be that the performance index deviates from the expected target of the construction hoist system to the minimum, or it can be that the comprehensive index of multiple performance indicators deviates from the comprehensive expected target of the construction hoist system to the minimum.

[0104] For example, the objective function could be to optimize the motor's output capacity torque-to-current ratio, or to minimize the overall energy loss of the system, or to minimize vibration, acceleration / deceleration time, and fluctuations in the comfort level of the elevator during its ascent and descent. Alternatively, the objective could be to minimize the deviation between the motor's current, torque, and speed and the expected target of the actual system under the same operating conditions.

[0105] Step S40: The selection of the electromechanical control equipment corresponding to the target simulation model is taken as the target selection of the construction hoist system.

[0106] It should be noted that the simulation model in the digital prototype system is obtained by simulating the actual motor, controller, transmission module, and mechanical components. That is, the performance of the motor model in the simulation model is the same as that of the actual motor, the performance of the controller model is the same as that of the actual controller, and the performance of the transmission module is the same as that of the actual transmission module.

[0107] In this embodiment, after obtaining the target simulation model in the digital prototype system, the model of the corresponding electromechanical control equipment can be determined as the target selection for the construction hoist. In this embodiment, by determining the target simulation model, the selection of the electromechanical control equipment model through trial operation in the construction hoist system is reduced, saving assembly and disassembly time and thus improving the efficiency of construction hoist system selection.

[0108] This application provides a selection method, system, equipment, and storage medium for a construction hoist system. Compared to the prior art, which involves selecting mechanisms based on equipment models and repeatedly adjusting equipment models based on the actual performance of the construction hoist system, resulting in low selection efficiency, this application, upon receiving a configuration selection instruction, obtains the selection requirements and type information of the construction hoist system from the instruction; selects a mechanical simulation model that conforms to the type information based on a preset calibration condition set; if the performance indicators of the initial digital prototype coupled with electromechanical control are optimal based on the mechanical simulation model, then selects a target simulation model that conforms to the selection requirements based on the mechanical simulation model and the preset conditions; and uses the selection of the electromechanical control equipment corresponding to the target simulation model as the target selection scheme for the construction hoist system. In this application, the selection requirements and type information of the construction hoist system are obtained from the configuration selection instructions. Based on the preset calibration conditions, a mechanical simulation model that meets the type information is selected, and the electromechanical control of the mechanical simulation model is coupled into an initial digital prototype. The performance index of the initial digital prototype is judged. If the performance index is optimal, a target simulation model that meets the selection requirements is selected based on the mechanical simulation model and the preset conditions. The selection of the electromechanical control equipment corresponding to the target simulation model is used as the target selection scheme for the construction hoist system. That is, in this application, the operation of the construction hoist system under different working conditions is simulated by the digital prototype, which replaces the repeated adjustment of equipment models based on the actual performance of the construction hoist system, thereby improving the selection efficiency of the construction hoist system.

[0109] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided, in which reference is made to... Figure 5 The step of evaluating whether the performance indicators of the initial digital prototype are optimal based on a preset evaluation function includes:

[0110] Step S01: If, based on the evaluation function, it is determined that the performance index of the initial digital prototype is not optimal, then, based on a preset optimization algorithm, the information data after optimizing the mechanical simulation model is determined.

[0111] The optimization algorithm can be the least squares method, iterative optimization method, model self-learning optimization, Newton's iteration method, particle swarm optimization algorithm, or other algorithms with similar effects.

[0112] In this embodiment, since the user may not be aware of the specific parameters of the key components of the construction hoist, the type information obtained may be somewhat incorrect. For example, the key components of the construction hoist require the use of a crank mechanism, but the user is unsure of the specific parameters of the crank mechanism. In order to ensure the connection relationship, internal mechanism and interaction relationship between the mechanical simulation model in the digital prototype and the construction hoist, if the calibration conditions are the same, the digital prototype needs to be calibrated and adjusted so that the component simulation structure in the digital prototype is the same as the key components of the construction hoist, thereby ensuring the accuracy, reliability and applicability of the digital prototype.

[0113] Step S02: Based on the information data, select an optimized mechanical model and replace the mechanical simulation model with the optimized simulation model;

[0114] In this embodiment, when optimizing the mechanical simulation model in the initial digital prototype, it is necessary to determine the optimization direction of the mechanical simulation model based on the running results of the initial digital prototype. That is, if the performance of the running structure of the digital prototype cannot reach the optimal level, then the component structures that cannot meet the requirements or lead to performance waste are identified. If the component structure cannot meet the requirements, the mechanical properties of the component mechanism are increased, such as stiffness, hardness, flexibility, and dimensions. If the component structure can meet the requirements but leads to performance waste, then the mechanical properties of the component structure are reduced.

[0115] Step S03: Under the calibration condition set, run the initial digital prototype again to obtain iterative performance indicators until the iterative performance indicators are optimal.

[0116] In this embodiment, the mechanical simulation model of the digital prototype is iteratively optimized using an optimization algorithm. This enables the digital prototype to avoid errors such as incorrect information about the type of construction hoist input by the user, and ensures that the performance of the digital prototype reaches its optimal state under calibration conditions. This improves the applicability of the construction hoist. In other words, by optimizing and calibrating the mechanical simulation model, users can ensure that the key components of the construction hoist are the same as those of the calibrated mechanical simulation model, thereby ensuring the reliability and authenticity of the selection through the digital prototype system.

[0117] In this embodiment, if the virtual operation result shows that the digital prototype cannot achieve optimal performance under calibration conditions, the mechanical simulation model is optimized until the digital prototype achieves optimal performance under calibration conditions, so that the mechanical simulation model is the same as the mechanical components of the construction hoist, making the final selection of the construction hoist system closer to reality.

[0118] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided. In this embodiment, before the step of selecting a target simulation model from the digital prototype system that meets the selection requirements information and the type information based on preset working conditions, the following steps are included:

[0119] Step C10: Based on the mechanical structure of the construction hoist system, determine the mechanical model and mechanism model of the virtual mechanical structure in the digital prototype;

[0120] Step C20: Based on the control information of the construction hoist system, determine the control model of the virtual control in the digital prototype;

[0121] Step C30: Based on the power information of the construction hoist system, determine the electromechanical coupling system model of the virtual power in the digital prototype;

[0122] Step C40: Generate the simulation model based on the mechanical model, the mechanism model, the control model, and the electromechanical coupling system model.

[0123] Among them, the mechanism model can be the interaction relationship between mechanical components, such as the transmission of force, the transmission relationship of kinematics and dynamics, mechanical dimensional deformation, stress, bending, elasticity, flexible torsional vibration of couplings, and the meshing of gear and rack transmissions.

[0124] The mechanical model can include mechanical accessories, structural connectors, car, chassis, wall attachments, couplings, rack and pinion transmission mechanisms, gear transmissions and reduction gearboxes, etc.

[0125] In this embodiment, basic mechanical models, mechanism models, electromechanical coupling system models, and control models of various types of construction hoists are first established in the digital prototype system so that users can choose according to their needs. After selection, based on the user's input of demand and type information, a digital prototype identical to the construction hoist that the user needs to select is further determined, thereby reducing user operations and saving modeling time.

[0126] Specifically, the key components of the electromechanical control coupling system model form a complete set of virtual equipment and simulation system, wherein the simulation system is a mapped twin system of the construction hoist system.

[0127] It should be noted that the key components of the electromechanical-control coupling system model form a complete set of virtual equipment and its control system. It is a mapping twin system that corresponds one-to-one with the actual system, and can simulate all the control logic, control variables, operating principles, operating status, electrical information, and mechanical operation information of the actual construction hoist system.

[0128] In this embodiment, a twin-mapped system simulation is used to model all the working processes of an actual construction hoist system. A control system composed of a virtual electromechanical-control coupling system model performs operational simulations, load simulations, and operational condition tests just like the actual system. Furthermore, the system's full-state information can be easily viewed and analyzed to evaluate the matching between the control and motor systems, the matching between the motor and the mechanical transmission system, and the actual mechanical load performance during the hoist's ascent and descent. Simultaneously, operational reliability and stability assessments can be performed. In this embodiment, the twin-mapped system reduces the error between the simulation process and the actual application of the construction hoist, ensuring the reliability and usability of the final selection, thereby improving the efficiency of construction hoist system selection.
