[0050] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0051] Figure 1 A flowchart of a hydraulic system design method provided by an exemplary embodiment of the present invention is applied to electronic devices, which may include but are not limited to computers, servers, tablet computers, etc. with simulation functions. Figure 1 , the design method includes the following steps:

[0052] Step 101: Display icons representing the mechanism model of components constituting the hydraulic system.

[0053] Each icon is correspondingly provided with at least one attribute parameter and a parameter value of the attribute parameter. The parameter value adopts the real parameter value of the attribute parameter of the commercially available component mapped by the component mechanism model.

[0054] The embodiment of the present invention provides a user interface for hydraulic system design, through which icons representing component mechanism models constituting the hydraulic system are displayed, so that the user can select the required component mechanism model to construct a hydraulic system model and perform simulation.

[0055] The component mechanism model may include but is not limited to a motor model, a hydraulic pump model, a relief valve model, an electromagnetic reversing valve model, a hydraulic cylinder model, a load model, a filter model, a four-way connector model, a three-way connector model, a fuel tank model, a throttle valve model, a one-way valve model, a servo valve model, an accumulator model, a displacement sensor model, a pressure sensor model, a flow sensor model, a temperature sensor model, a cleanliness tester model, a speed sensor model, a torque sensor model, a speed / torque sensor model, and an IO sensor model, etc.

[0056] Each component has related attribute parameters, such as the attribute parameters of a motor including maximum speed, maximum torque, speed, torque, power, efficiency, brand, cost and life, etc. Users generally select components to build a hydraulic system based on the parameter values ​​of the attribute parameters. Therefore, at least one attribute parameter and the parameter value of the attribute parameter are set for each icon.

[0057] Step 102: Determine whether there is a target icon in the selected icons.

[0058] Wherein, at least one attribute parameter of the target icon includes multiple parameter values.

[0059] In step 102, if the judgment result is yes, that is, there is at least one target icon among the selected icons, and multiple combinations of hydraulic system models can be obtained based on the selected icons, then execute step 103; if the judgment result is no, only one combination of hydraulic system models can be obtained based on the selected icons, then execute step 104.

[0060] For example, if the icons selected by the user represent the motor model, hydraulic pump model, electromagnetic reversing valve model, hydraulic cylinder model, load model, oil tank model and pressure sensor model respectively, among which the brand (attribute parameter) of the hydraulic cylinder model includes brand a, brand b and brand b, and the brand of the hydraulic pump model includes brand c and brand d, that is, the brands of the hydraulic cylinder model and the hydraulic pump model both include multiple parameter values, then it is determined that there are 2 target icons in the selected icons. Among them, brand a to brand d represent the parameter values ​​of the brand (attribute parameter).

[0061] In one embodiment, before step 102, it is determined whether the component mechanism model corresponding to the selected icon meets the hydraulic system composition conditions. If the component mechanism model corresponding to the selected icon meets the hydraulic system composition conditions, step 103 is executed; if the component mechanism model corresponding to the selected icon does not meet the hydraulic system composition conditions, a prompt message can be generated to remind the user that the currently selected icon does not meet the hydraulic system composition conditions and needs to reselect the icon. The so-called meeting the hydraulic system composition conditions means that the component mechanism model corresponding to the selected icon can form a hydraulic system model, and there is no lack of component mechanism models and no redundant component mechanism models.

[0062] Step 103: Combine the component mechanism models of the selected icons into multiple component groups.

[0063] Each device group includes the device mechanism models of all selected icons, and the parameter values ​​corresponding to the device mechanism models in each device group are not completely the same.

[0064] Still taking the selected icons representing the motor model, hydraulic pump model, electromagnetic reversing valve model, hydraulic cylinder model, load model, oil tank model and pressure sensor model as an example, since the brands of the hydraulic cylinder model include 3 brands and the brands of the hydraulic pump model include 2 brands, 6 combinations can be obtained, that is, 6 groups of device groups, which are:

[0065] Motor model, hydraulic pump model of brand C, electromagnetic reversing valve model, hydraulic cylinder model of brand A, load model, oil tank model and pressure sensor model;

[0066] Motor model, hydraulic pump model of brand c, electromagnetic reversing valve model, hydraulic cylinder model of brand b, load model, oil tank model and pressure sensor model;

[0067] Motor model, hydraulic pump model of brand C, electromagnetic reversing valve model, hydraulic cylinder model of brand C, load model, oil tank model and pressure sensor model;

[0068] Motor model, hydraulic pump model of brand d, electromagnetic reversing valve model, hydraulic cylinder model of brand a, load model, oil tank model and pressure sensor model;

[0069] Motor model, hydraulic pump model of brand d, electromagnetic reversing valve model, hydraulic cylinder model of brand b, load model, oil tank model and pressure sensor model;

[0070] Motor model, hydraulic pump model of brand d, electromagnetic reversing valve model, hydraulic cylinder model of brand c, load model, oil tank model and pressure sensor model.

[0071] The above six device groups all include the device mechanism models of all the selected icons, and the parameter values ​​corresponding to the device mechanism models in each device group are not completely the same.

[0072] Step 104: For each component group, a hydraulic system model is constructed and simulated to obtain simulation characteristic parameters of each component group.

[0073] There are several groups of device groups, and correspondingly several hydraulic system models can be constructed. For example, if step 103 obtains 6 groups of device groups, correspondingly 6 hydraulic system models can be constructed; if there is only 1 group of device groups, 1 hydraulic system model is constructed. By connecting all the component mechanism models in each group of device groups, the corresponding hydraulic system model can be obtained. Regarding the connection of the component mechanism models, the connection can be established by manual dragging by the user, or it can be established automatically. The embodiment of the present invention does not specifically limit the connection method.

[0074] The hydraulic system model is simulated, and the simulation characteristic parameters obtained may include, but are not limited to, temperature, flow, displacement, pressure, acceleration of the reciprocating component, speed of the reciprocating component, etc. The simulation characteristic parameters are parameters that can characterize the operating state of the hydraulic system.

[0075] Step 105 : Input the simulation characteristic parameters of each component group into the performance prediction model to predict the performance parameters of the hydraulic system composed of each component group.

[0076] The performance prediction model can be obtained by pre-training a neural network based on a large number of training samples. The training process of the model can be found in the relevant technical description and will not be repeated here.

[0077] The input parameters of the performance prediction model include simulation characteristic parameters, and the output parameters include performance parameters, and the performance parameters characterize the predicted performance of a hydraulic system constructed using the components in the device group.

[0078] The performance parameters may include, but are not limited to, life, driving force, and other parameters that can characterize the performance of the hydraulic system. It is understandable that the performance parameters output by the performance prediction model are related to the training samples. If the training samples include the life of the hydraulic system, the performance prediction model has the ability to predict the life, and the performance parameters it outputs include the life; if the training samples include the driving force of the hydraulic system, the performance prediction model has the ability to predict the driving force, and the performance parameters it outputs include the driving force.

[0079] In one embodiment, the performance parameters of the hydraulic system are also predicted in combination with the environmental simulation parameters. When predicting the performance parameters, the environmental simulation parameters are also obtained, and the simulation characteristic parameters and environmental simulation parameters of each component group are input into the performance prediction model to predict the performance of the hydraulic system composed of each component group.

[0080] The parameter values ​​of the environmental simulation parameters can be set according to actual needs. The environmental simulation parameters characterize the working conditions of the hydraulic system, and may include but are not limited to ambient temperature, ambient humidity, air pressure, etc. The performance parameters of the hydraulic system are predicted by combining the environmental simulation parameters, and the prediction results are closer to the working conditions and more accurate.

[0081] In this embodiment, the input parameters of the performance prediction model include environmental simulation parameters and simulation feature parameters, and the output parameters include performance parameters. It can be understood that when performing model training, the training samples also include environmental simulation parameters.

[0082] It should be noted that the performance prediction model can be one or more. Taking the life prediction model as an example, see Figure 2a , set up a life prediction model, input the simulation characteristic parameters of each component model into the life prediction model, and predict the life of the hydraulic system; or, refer to Figure 2b , a life prediction model is set for each component, and the simulation characteristic parameters of each component model are input into the corresponding life prediction model to predict the component life. Finally, the life of the hydraulic system is obtained according to the output results of each life prediction model.

[0083] Step 106: Generate design recommendations for the hydraulic system based on the predicted performance parameters.

[0084] The design suggestions may include the performance parameters, attribute parameters and corresponding parameter values ​​of each component group, and may also directly indicate which component group has the best performance. The design suggestions may be used as a reference for the selection of components for the hydraulic system.

[0085] In the embodiment of the present invention, the component mechanism model and the performance prediction model of the hydraulic system are integrated to analyze and predict the performance of the hydraulic system with high accuracy before the hydraulic system is built, which can provide a reference for the selection and construction of components of the hydraulic system.

[0086] Long life is an important indicator for hydraulic system design. In one embodiment, the performance parameters of the hydraulic system include life, and the performance prediction model adopts a life prediction model. In step 105, the simulation characteristic parameters of each component group are input into the life prediction model, and the life prediction model predicts the life of the hydraulic system composed of each component group. In step 106, a design suggestion for the hydraulic system is generated according to the life. For example, the design suggestion includes the ranking of each component group according to the life, and the longer the life, the higher the ranking, indicating that the performance of the component group is the best; or the component group with the longest life is the optimal group, and the optimal group is displayed in the design suggestion.

[0087] In the embodiment of the present invention, the component mechanism model and life prediction model of the hydraulic system are integrated to analyze and predict the life of the hydraulic system with high accuracy before the hydraulic system is built, which can provide a reference for the selection and construction of components of the hydraulic system.

[0088] Low cost is also an important indicator for hydraulic system design. In one embodiment, in step 106, a design suggestion for the hydraulic system is generated based on life and cost. For example, if the device group with the longest life includes multiple groups, the device group with the lowest cost among the multiple device groups with the longest life is selected as the optimal group, and the optimal group is displayed in the design suggestion; or weights are set for cost and life, and each device group is scored according to cost, life, and weight, and the device group with the highest score is selected as the optimal group, and the optimal group is displayed in the design suggestion; or weights are set for cost and life, and each device group is scored according to cost, life, and weight, and the design suggestion includes the ranking of each device group according to the score. Among them, the cost of each device group represents the cost of building a hydraulic system using the device group.

[0089] In the embodiment of the present invention, the component mechanism model and life prediction model of the hydraulic system are integrated, combined with the cost, and the cost and life of the hydraulic system are taken as the optimal goals to optimize the selection of components and obtain the optimal solution for cost and life.
