[0059] Embodiments of the present invention provide a hydraulic valve control method, system and device to flexibly, quickly and simply implement hydraulic valve control.

[0060] The above-mentioned exemplary hydraulic valve control system at least includes: a hydraulic control device. Please refer to Figure 1 , and the hydraulic control device may further include: a controller 1 and a hydraulic valve 2.

[0061] In other embodiments of the present invention, the above system may further include a host computer 3 for configuring and loading a modular program that can run on the controller 1.

[0062] Please refer to Figure 2The hydraulic valve control method performed by the hydraulic valve control system exemplarily includes the following steps:

[0063] S1: The controller loads the modular program.

[0064] The modular program includes at least: at least one general function module, the calling sequence of each general function module, the input-output relationship between the general function modules, and the connection relationship between the interface of the hydraulic threshold and the general function module.

[0065] Each general function module encapsulates multiple functions.

[0066] See also Figure 3 or Figure 4 The schematic diagram of the universal functional module shown is that the universal functional module provides at least one pin to the outside.

[0067] by Figure 3 Take the general function module shown as an example, see Figure 5 , the pins contain definitions of multiple variables and function operations on the variables ( Figure 5 The function operation here is completed by the function encapsulated by the module.

[0068] Of course, there may also be function operations between the pins inside the module.

[0069] The above-mentioned input-output relationship may include: the connection relationship between the pins of the modules.

[0070] S2: The controller executes each common function module in the modular program according to the above calling sequence, input-output relationship and connection relationship to perform data interaction with the corresponding interface of the hydraulic valve.

[0071] The process of data interaction is the process of controlling the hydraulic valve.

[0072] It can be seen that in the embodiment of the present invention, the modular program loaded and executed by the controller includes at least one general function module, the calling sequence and input-output relationship of the general function module, and the connection relationship between the hydraulic valve interface and the general function module.

[0073] Different general function modules, or different calling sequences, input-output relations, and connection relations, constitute different modular programs. Therefore, modular programs can be obtained flexibly, quickly, and simply through different combinations to control hydraulic valves to achieve valve-controlled hydraulic applications, pump drives with variable speeds, etc.

[0074] Meanwhile, each general function module encapsulates multiple functions and provides pins externally. Each general function module can implement certain functions or operations by itself. Existing general function modules can be directly used without the need to rewrite the logic, achieving scriptless operation, and to a certain extent simplifying the configuration process and improving the configuration speed.

[0075] As mentioned above, the system may include a host computer 3, which can be used to configure and load modular programs. How to configure modular programs will be introduced in detail below.

[0076] Figure 6 An exemplary process for configuring a modular program is shown, including:

[0077] S61: The host computer provides a configuration unit and a loading unit for human-computer interaction.

[0078] The configuration unit may include a programming interface and a general function module selection interface.

[0079] Among them, the general function module selection interface is used to display the published general function modules. For example, please refer to Figure 7 , the general function module selection interface includes function module a, function module b, etc.

[0080] S62: The user selects and moves the general function module to the programming interface in the general function module selection interface.

[0081] Here, the user refers to the editing personnel using the host computer.

[0082] It should be noted that what the user sees is the general function module selection interface and the programming interface, and there is a series of logical operations behind the interface for support.

[0083] S63: The configuration unit displays the general function modules added to the programming interface.

[0084] Figure 7 The programming interface in shows the general function modules added to the programming interface.

[0085] S64: The configuration unit records the identifier of the general function module and the addition order of the general function module as the call order.

[0086] That is, the general function module added first will be executed first in the follow-up.

[0087] Of course, the user can also manually modify or input the call order of the added general function modules.

[0088] S65: The user issues a first pin connection command.

[0089] The first pin connection command includes: the connection relationship between pins of modules.

[0090] During actual operation, the user can add a connection line between two pins on the programming interface, which is equivalent to issuing a first pin connection command.

[0091] More specifically, various operation controls can be provided in the programming interface, such as a connection line control. The user can click on the connection line control with the mouse and then add a connection line between two pins.

[0092] The user can execute S65 multiple times to complete the connection of pins between modules.

[0093] S66: The configuration unit receives the first pin connection command, connects the corresponding pins according to the first pin connection command and displays them, and records the connection relationship of pins between modules according to the first pin connection command.

[0094] Figure 7 The connected pins are shown therein.

[0095] S67: The user issues a second pin connection command.

[0096] The second pin connection command includes: the connection relationship between the interface of the hydraulic valve and the pins of the corresponding general function module.

[0097] During actual operation, the user can add a connection line between the interface and the pin on the programming interface, which is equivalent to issuing a second pin connection command.

[0098] More specifically, various operation controls can be provided in the programming interface, such as a connection line control. The user can click on the connection line control with the mouse and then add a connection line.

[0099] The user can execute S67 multiple times to complete the connection between the interface of the recording hydraulic valve and the pins of the corresponding general function module.

[0100] S68: The configuration unit receives the second pin connection command, connects the interface of the hydraulic valve and the pins of the corresponding general function module according to the second pin connection command and displays them, and records the connection relationship between the interface of the hydraulic valve and the pins of the corresponding general function module.

[0101] It should be noted that the execution order of S65 and S67 can be interchanged, which depends on the user's operation.

[0102] S69: When receiving the confirmation instruction, the configuration unit generates a modular program according to the recorded identifiers, call sequences, and connection relationships of the general function modules.

[0103] The configuration unit can provide a "confirm" or "generate" button. When the user clicks it, the confirmation instruction is issued.

[0104] In addition, the configuration unit can also receive a delete command to delete the corresponding general function module in the programming interface or the general function module selection interface. The delete command can be issued through a specific delete button, or by right-clicking the mouse and selecting the "Delete" option in the shortcut menu.

[0105] Of course, the configuration unit can also provide a query function so that users can quickly find common functional modules through keywords, numbers, etc.

[0106] S610: When receiving the loading instruction, the loading unit loads the modular program specified by the loading instruction into the controller serving as the lower computer.

[0107] The configuration unit may provide a "load" button, and the user issues a loading instruction by clicking the button.

[0108] Users can choose to load a generated modular program, or customize the modular program first and then load it.

[0109] In addition to configuring modular programs, the configuration unit can also be used to configure general function modules. The configuration unit may also include: a general function module configuration interface; the general function module configuration interface is used to create a new general function module, modify or delete an established general function module, verify an established general function module, and publish a general function module (add a function module to a function module selection interface).

[0110] Of course, what users see is the general function module configuration interface, and there is a series of logical operations behind the interface to support it.

[0111] The following will introduce in detail how to configure the common function modules.

[0112] 1. Create a new general function module.

[0113] See also Figure 8 The process of creating a new general function module executed by the general function module configuration interface exemplarily includes:

[0114] S81: Receive a new creation command.

[0115] In one example, the configuration module may provide a new module button, and the user may issue a new command by clicking the new button.

[0116] S82: Create a new general function module.

[0117] The general function module is blank at this time.

[0118] S83: Load the preset variable configuration file and function configuration file.

[0119] The variable configuration file contains: a variety of variables to choose from and the definition of the variables;

[0120] The function configuration file includes: multiple selectable functions;

[0121] As mentioned above, the general function module includes pins, and each pin includes the definition of multiple variables and the function operation on the variables.

[0122] Load the variable configuration file and the function configuration file, and then the newly created general function module can be edited on the general function module configuration interface.

[0123] S84: When receiving a pin creation command, add a pin to the newly created general function module and provide a configuration interface.

[0124] In one example, a pin creation button can be provided on the general function module configuration interface, and the user can issue a pin creation command by clicking this button.

[0125] Alternatively, a pin control can be provided on the general function module configuration interface, and the user can add a pin by dragging the pin control to the corresponding position of the general function module with the mouse.

[0126] For the added pins, the user can double-click a certain pin, and the general function module configuration interface can also pop up a configuration interface.

[0127] The configuration interface includes a pin configuration template. Figure 5 The interior of the shown pin is an exemplary pin configuration template.

[0128] Specifically, the pin configuration template can include multiple configuration lines, and configuration lines can be added according to the situation.

[0129] Please refer to Figure 9 , and each configuration line can be deployed with a variable acquisition control and a function acquisition control.

[0130] In one example, the variable acquisition control can be in the form of a drop-down menu. Similarly, the function acquisition control can be in the form of a drop-down menu. Of course, manual input is also supported.

[0131] S85: When the variable acquisition control is triggered, present the variables in the variable configuration file in the configuration interface for selection.

[0132] Such as Figure 9 , when the variable acquisition control is triggered, the variables in the variable configuration file will be presented in the form of a drop-down menu.

[0133] S86: Input the selected variable into the corresponding configuration line of the pin configuration template.

[0134] Still taking Figure 9For example, if the user selects a certain variable, the variable will be added to the corresponding configuration line of the pin configuration template.

[0135] Alternatively, in other embodiments of the present invention, the variable acquisition control can also receive a new variable input by the user and input the new variable into the corresponding configuration line of the pin configuration template.

[0136] S87: When the function acquisition control is triggered, present the functions in the function configuration file for selection.

[0137] As Figure 9 shown, when the function acquisition control is triggered, the functions in the function configuration file will be presented in the form of a drop-down menu.

[0138] S88: Input the selected function into the corresponding configuration line of the pin configuration template.

[0139] Still taking Figure 9 as an example, if the user selects a certain function, the function will be added to the corresponding configuration line of the pin configuration template.

[0140] Alternatively, in other embodiments of the present invention, the function acquisition control can also receive a new function input by the user (such as engineering code) and input the new function into the corresponding configuration line of the pin configuration template.

[0141] In an example, the pin identifier and the corresponding pin configuration information of each pin can be stored in the pin configuration file in the form of key-value pairs. The pin configuration information can include the aforementioned input variables and the functions corresponding to the variables.

[0142] In addition, the added new variables will be stored in the above variable configuration file. Similarly, the added new functions will be stored in the above function configuration file.

[0143] Second, modify or delete the established general function module.

[0144] Modifying the general function module includes modifying the pin name, the variables and functions inside the pin. For the modification of the variables and functions inside the pin, the aforementioned controls can be used to re-select or input variables / functions, which will not be elaborated here.

[0145] In addition, the general function module configuration interface provides a deletion function. For the selected general function module, a right-click deletion operation can be performed, or a deletion button can be provided. The user can select the general function module and then click the deletion button to complete the deletion.

[0146] Of course, the variables and functions inside the pin can also be deleted, and the operation is similar to the deletion of the general function module, which will not be elaborated here.

[0147] Third, verify the general function module.

[0148] See also Figure 10 The verification process performed by the general function module configuration interface exemplarily includes:

[0149] S101: Input a preset input value to a first designated pin of a target general function module.

[0150] In addition to presetting the input value, the output value (expected value) also needs to be preset.

[0151] The first designated pin is a pin for inputting data.

[0152] S102: receiving a value outputted by a second designated pin as an actual value.

[0153] The second designated pin and the first designated pin may be the same pin or different pins.

[0154] S103: Compare the actual value with the preset expected value. If they are consistent, the verification is passed; otherwise, the verification fails.

[0155] After the verification of each pin is passed, the user can choose to add the established common function module to the function module selection interface.

[0156] The embodiment of the present invention further claims protection for a hydraulic control system, wherein the hydraulic valve control system exemplarily comprises at least: a hydraulic control device.
