Description

In actual work, the structure calculation is changed along with the project, and when the project occurs, such as bidding, construction organization design, construction and the like, the structure calculation is frequently performed, and when the project does not occur or the project is simpler, the structure calculation frequency is relatively low. Under the charging mode of the existing commercial structure calculation software, when the construction unit needs to use the structure calculation, the construction unit often purchases the software authorization at a considerable fee exceeding the self use requirement, but does not perform the structure analysis according to the requirement, so that the user income is reduced and the software user runs off. In addition, the client program has higher requirement on the CPU of the client, and the hardware cost of structural calculation is increased; the client mode causes the unreliability of software upgrading, each software upgrading means that a user needs to reinstall a client program, re-authorize/pay and the like, and the situation can cause multiple versions of product maintenance to happen, and old version software robs new version software users; moreover, the local storage of the files easily causes large file dispersion and easy loss, thereby causing the loss and waste of data resources.

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.
Under the charging mode of the existing commercial structure calculation software, when the construction unit needs to use the structure calculation, the construction unit often purchases the software authorization at a considerable fee exceeding the self use requirement, so that the user income is reduced and the software user runs off. In addition, the client program has higher requirements on the CPU of the client, and the hardware cost of the structural calculation is increased. Therefore, the application provides an engineering structure finite element analysis method, which avoids using a client with higher hardware requirements by adopting an engineering construction structure computing cloud platform of a BS framework; by carrying out complexity analysis on the three-dimensional model, the flexibility of a charging mechanism is increased.
Referring to fig. 1, the embodiment of the invention discloses an engineering structure finite element analysis method which is applied to an engineering construction structure computing cloud platform, wherein the engineering construction structure computing cloud platform comprises a personal space service and a structure model design service which are positioned at a webpage client, and a model charging service and a structure finite element analysis service which are positioned at a cloud; wherein the method comprises the following steps:
step S11, acquiring user login information through the personal space service, and determining whether the cloud platform use right is provided or not based on the user login information; the user login information includes a user identification.
In this embodiment, before the user login information is obtained through the personal space service, obtaining the user login information through the personal space service and storing the user login information in a cloud database may be further included; the user registration information comprises a user identifier; and distributing a preset storage space and cloud platform use rights for the user identification. It can be understood that the user uses the personal space service to register the engineering construction structure computing cloud platform, stores the registration information of the user through the cloud database, corresponds to a unique user identification for each user, provides a certain storage space for each user for free use after the user is successfully registered, and distributes the cloud platform use right for each user.
In this embodiment, a user uses a personal space service to log in an engineering construction structure computing cloud platform, and if the user logs in successfully, the user is indicated to have the cloud platform use right; if the user login fails, indicating that the user is not registered, and needing to register first; or the account number or the password input by the user is wrong, and the account number and the password are input again.
And step S12, if the user identification is provided, obtaining structural model information through the structural model design service, and generating a three-dimensional model and a three-dimensional model identification corresponding to the user identification in real time according to the structural model information.
In this embodiment, if the cloud platform usage right is provided, user engineering data corresponding to the user identifier is found out from the cloud database, and the user engineering data is displayed in a corresponding page of the personal space service; the user engineering data comprises all historical engineering structure calculation items and payment states respectively corresponding to the historical engineering structure calculation items. It can be understood that, as shown in fig. 2, after the user logs in successfully, that is, after the user has the cloud platform usage right, when accessing the personal space page, all user engineering data corresponding to the user identifier of the user is matched from the cloud database, and is displayed in the personal space page corresponding to the personal space service for display. The user engineering data comprises, but is not limited to, all historical engineering structure calculation items, payment states respectively corresponding to the historical engineering structure calculation items, calculation results respectively corresponding to the historical engineering structure calculation items, creation time and current user balance. In addition, the left column of the personal space page displays a search column, project platform names and all project lists, the required project can be quickly inquired through the search column, and the corresponding project can be directly opened by clicking any one of the all project lists.
In this embodiment, if the cloud platform usage right is provided, before the structure model information is obtained through the structure model design service, the method may further include obtaining a structure project creation instruction through the personal space service, and creating a corresponding newly-added engineering structure calculation project based on the structure project creation instruction; marking the newly added project structure calculation item as an unpaid state, storing the newly added project structure calculation item and a payment state corresponding to the newly added project structure calculation item in a cloud end and displaying the newly added project structure calculation item in a corresponding page of the personal space service, and then allowing the structure model design instruction aiming at the newly added project structure calculation item to be acquired through the personal space service; triggering the step of acquiring structural model information through the structural model design service when the structural model design instruction is acquired; correspondingly, after submitting the three-dimensional model to the structure finite element analysis service to perform structure finite element analysis on the three-dimensional model, the method can further comprise storing an engineering calculation book obtained by analysis into the newly added engineering structure calculation item corresponding to the user identifier through the personal space service, and marking a payment state corresponding to the newly added engineering structure calculation item as a paid state. It can be understood that the user creates a new project structure calculation item using the personal space service, and the user provides data such as structure types, project information and the like related to the new project structure calculation item, then marks the new project structure calculation item as an unpaid state, and stores the new project structure calculation item and a payment state corresponding to the new project structure calculation item in the cloud and displays the new project structure calculation item in a personal space page corresponding to the personal space service. And then, the user can jump to the structural model design service by clicking the newly added project structure calculation project so as to design the model. If the three-dimensional model corresponding to the project is submitted to the structure finite element analysis service, the structure finite element analysis service is used to perform structure finite element analysis on the three-dimensional model, and the generated information such as the engineering calculation book is stored under the new project structure calculation project corresponding to the current user through the personal space service, and the payment state is updated, that is, the unpaid state corresponding to the new project structure calculation project is updated to the paid state.
In this embodiment, before acquiring the structure project new instruction through the personal space service, determining whether the current remaining storage space corresponding to the user identifier meets a preset storage space condition may be further included; if not, displaying storage space recharging prompt information in the current interface of the webpage client to prompt a user to expand the storage space; and if so, allowing to trigger the step of acquiring the structure project new instruction through the personal space service. It can be understood that before the user uses the personal space service to create the project structure calculation project, that is, before the user obtains the structure project creation instruction, it needs to determine whether the current remaining storage space corresponding to the user meets the preset storage space condition, if not, it indicates that the current remaining storage space of the user is insufficient, and at this time, the storage space recharging prompt information is displayed in the current interface of the webpage client to prompt the user to expand the storage space in a recharging manner; and if so, allowing to trigger the step of acquiring the structure project new instruction through the personal space service.
In this embodiment, as shown in fig. 3, after jumping to the structural model design service, in order to avoid the problem caused by upgrading the conventional business structural analysis software, the present application uses web WebGL technology as the design and rendering basis of the structural model design service. The structure model design service provides a three-dimensional interactive structure model design function based on the webpage, and can render and generate three-dimensional graphic information in real time according to the structure model information input by a user at the webpage end.
In this embodiment, after determining whether the cloud platform usage right is provided based on the user login information, if the cloud platform usage right is provided, a model sharing instruction triggered by a target user is obtained through the personal space service, the created historical three-dimensional model is shared based on the model sharing instruction, and after obtaining a model collection operation of the historical three-dimensional model shared by other users for the target user, a failure process is performed on a sharing event corresponding to the collected historical three-dimensional model. It can be understood that after the target user logs in successfully, i.e. after the target user has the cloud platform usage right, the target user can share the historical three-dimensional model which has completed design through the personal space service, and after other users perform model collection operation on the historical three-dimensional model shared by the target user, the sharing event corresponding to the collected historical three-dimensional model is invalid, i.e. the three-dimensional model shared by the target user can only be collected by the other users once, and after one model collection, the collected three-dimensional model can not be collected by the other users any more.
In this embodiment, after determining whether the cloud platform usage right is provided based on the user login information, if the cloud platform usage right is provided, the method may further include acquiring a model collection instruction triggered by the target user through the personal space service, collecting a historical three-dimensional model shared by other users by using the model collection instruction, generating a model data copy based on a model identifier corresponding to the collected historical three-dimensional model, and associating the model data copy with a user identifier of the target user. It can be understood that after the target user logs in successfully, that is, after the target user has the cloud platform usage right, the target user can perform model collection on the historical three-dimensional model shared by others through the personal space service, but instead of directly associating the model identifier corresponding to the collected historical three-dimensional model with the user identifier of the target user, the same model data copy is generated according to the model identifier corresponding to the collected historical three-dimensional model, and then associating the model data copy with the user identifier of the target user, so that the target user can modify the model data copy, but cannot modify the original collected historical three-dimensional model.
And S13, acquiring the three-dimensional model submitted to the model charging service, inquiring whether the three-dimensional model identification exists from the model identifications stored in the cloud, and if not, carrying out complexity analysis on the three-dimensional model by using the model charging service so as to obtain the model charging price of one-time structural analysis.
In this embodiment, a user submits a three-dimensional model to a model charging service, and a cloud platform firstly compares a three-dimensional model identifier corresponding to the three-dimensional model submitted by the current user with a model identifier stored in a cloud, and determines whether model charging operation is performed on the three-dimensional model. If the three-dimensional model identifier does not exist in the model identifier stored in the cloud, the fact that the three-dimensional model is not subjected to model charging operation is indicated, and then complexity analysis is carried out on the three-dimensional model by using model charging service, so that model charging price of primary structure analysis is obtained. If the three-dimensional model identifier exists in the model identifiers stored in the cloud, the three-dimensional model is indicated to be subjected to model charging operation, and then a model identifier to be compared, which is consistent with the three-dimensional model identifier, is determined from the model identifiers stored in the cloud; judging whether the first model parameter corresponding to the three-dimensional model identifier changes relative to the second model parameter corresponding to the model identifier to be compared; if the model information is changed, updating the model information stored in the cloud and corresponding to the three-dimensional model identifier, and jumping to the step of acquiring the three-dimensional model submitted to the model charging service. It should be noted that the first model parameter and the second model parameter include, but are not limited to, a node number, a cable unit number, and a working condition number. If the first model parameter corresponding to the three-dimensional model identifier is unchanged relative to the second model parameter corresponding to the model identifier to be compared, the model charging price is 0. In this way, the method and the device calculate the corresponding model charging price of primary structural analysis by carrying out complexity analysis on the three-dimensional model, and change the traditional charging mode adopting the service time (month, bao Ji and year) and the number of users into the charging mode adopting the engineering structural complexity and charging each time each use is carried out, so that the problem of user loss caused by contradiction between the traditional charging mode and actual projects is solved, and the flexibility of a charging mechanism is increased.
And S14, if the current balance of the user is not less than the model charging price, submitting the three-dimensional model to the structure finite element analysis service to perform structure finite element analysis on the three-dimensional model, and returning an analysis result to the structure model design service to perform rendering display.
In this embodiment, after obtaining a model charging price for primary structural analysis, a user identifier is required to query a corresponding current user balance, and determine whether the current user balance is smaller than the model charging price, if the current user balance is smaller than the model charging price, the three-dimensional model is saved to the cloud end in a distributed cache manner, a difference between the model charging price and the current user balance is determined, and then balance charging prompt information for the difference is returned to the structural model design service for display; determining whether a recharging instruction aiming at balance recharging prompt information is acquired; if a recharging instruction is acquired within a preset time period, determining the current user balance after recharging based on the recharging instruction, deducting a model charging price from the current user balance after recharging through a model charging service, and jumping to a step of submitting the three-dimensional model to a structural finite element analysis service; and if the recharging cancellation instruction is acquired or the recharging instruction is not acquired in a preset time period, canceling the recharging operation of the time, and deleting the three-dimensional model stored to the cloud. It can be understood that, as shown in fig. 4, if the balance of the current user is insufficient, the three-dimensional model is stored to the cloud end in a distributed cache manner, then the difference between the balance of the current user and the charging price of the model is calculated, and the balance charging prompt information for the difference is returned to the structural model design service for display. The difference is the cost to be paid this time in fig. 4, and the model charging price is the cost to be calculated this time in fig. 4. The user can select to recharge or cancel recharge within a preset time period, if the user finishes recharging, the model charging price calculated at the time is deducted from the current user balance after recharging through the model charging service, the deducted current user balance is stored into the personal space service, and then the step of submitting the three-dimensional model to the structure finite element analysis service is skipped, wherein the user can recharge the balance by scanning the two-dimensional code; and if the user cancels recharging, canceling the recharging operation, and deleting the three-dimensional model stored in the cloud.

Based on the previous embodiment, the present application describes the complete process of charging price calculation and structure finite element analysis for engineering structure calculation items, and next, the present application will explain in detail how to use model charging service to analyze complexity of three-dimensional model. Referring to fig. 6, an embodiment of the present invention discloses a complexity analysis process.
And S21, obtaining the total number of nodes, the total number of working conditions and the number of cable units of the three-dimensional model by using a model charging service.
In this embodiment, as shown in fig. 7, a user inputs structural model information in a structural model design service of a web client, and a cloud platform renders in real time according to the input structural model information to generate a three-dimensional model. The structural model information comprises, but is not limited to, node coordinates, unit information, unit connection information, cable units, section information, material information, support information and working condition information. Specifically, the node coordinates are displayed by using points on the webpage client, so that the graphic rendering burden of the webpage is reduced, and the particle system is adopted on the webpage client to display each node. The unit information is formed by connecting two nodes, is represented by lines on the webpage client, and reduces webpage graphic rendering burden in a mode of batch data transmission to a GPU (Graphics Processing Unit, graphic processor) like the nodes. The unit connection information is the connection type of the nodes at the two ends of the unit, and is divided into consolidation and articulation, the webpage client side performs rendering in a manner of a sprite, so that the loading speed of a page can be reduced to a certain extent, and the pressure of a server is relieved to a certain extent. The cable units include determining whether each unit is a cable unit and recording related information. The cross section information is information contained in each unit, the webpage client displays the shape of the cross section of each unit in real time, and for each type of cross section, geometric top point data are transmitted to the GPU in batches, so that webpage rendering burden is reduced, and various common cross section characteristic values (moment of inertia, cross section area, bending moment resistance and the like) of engineering can be obtained through a standard database provided by the cloud platform during modeling. The material information is the material adopted by each unit, the webpage client does not render, and the characteristic values (elastic modulus, dead weight and the like) of various materials can be obtained through a standard database provided by the cloud platform during structural model design. The standoff information includes a determination of whether each node has a standoff and the web page client renders through the sprite. The working condition information is rendered on the webpage client in real time through graphics, various loads born by the current working condition model are displayed, and the load information comprises node force, unit concentrated force, unit uniform force, temperature, forced displacement, cable tensioning and the like, so that a design method of a plurality of working conditions of a single model is supported.
In this embodiment, after the user completes the design of the three-dimensional model and submits the three-dimensional model to the model charging service through the structural model design service, the model charging service may obtain the total number of nodes, the total number of working conditions and the number of cable units corresponding to the submitted three-dimensional model.

In this embodiment, it is required to determine whether the total number of working conditions is a preset value, where the preset value may be 1. If the total number of working conditions is a preset value of 1, the multi-working-condition coefficient can be set to 0, and the model charge determining operation is triggered. Considering that the duration and CPU occupation of one-time structure analysis are mainly related to the number of nodes and the number of working conditions, the more the number of the nodes is, the smaller the granularity of finite element analysis is, and the more detailed the calculation result is; the greater the number of conditions, the greater the number of times that the calculations need to be repeated according to different loads. Therefore, in the preset charging calculation formula, the node number and the total working condition number of the three-dimensional model are mainly considered. Specifically, the preset charging calculation formula is as follows:
；
Wherein a represents a basic price of a preset primary structural analysis; b represents the total number of nodes; c represents a preset calculation price of a single node; n represents the total number of working conditions; f represents a multiple working condition coefficient; r represents a preset cable unit calculation unit price; m represents the number of cable units; v represents the model charging price.
And step S24, if not, taking a value selected from a preset working condition coefficient range as the multi-working condition coefficient, and triggering the model charge determining operation.
In this embodiment, if the total number of working conditions is not the preset value 1, the engineering construction structure calculation cloud platform selects a decimal from the preset working condition coefficient range (between 0 and 1) as the multi-working condition coefficient, and then triggers the model charging determination operation in step S23 to determine the model charging price of the primary structural analysis corresponding to the three-dimensional model.
Therefore, the model charging price of the primary structure analysis is obtained by carrying out complexity analysis on the three-dimensional model, the problem that a user purchases software authorization with a considerable fee beyond the use requirement of the user caused by using a traditional charging mode is avoided, and the flexibility of a charging mechanism is improved due to the fact that the user is charged according to the complexity of the three-dimensional model, so that the loss of the user is relieved, and the use feeling of the user is improved.
