Traditional hydraulic control systems usually adopt fixed control strategies, which are difficult to adjust dynamically according to real-time working conditions. This static control method cannot cope with complex and changeable working environments, resulting in control lag or instability in the hydraulic system when responding to load changes.

It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0013] Please refer to the attached Figure 1 , this application provides a central hydraulic source configuration method based on hydraulic terminal equipment networking sharing analysis, which specifically includes the following steps: Step 1: Obtain equipment specification information of the networked hydraulic terminal equipment and construct a hydraulic network topology, wherein each parallel terminal branch in the hydraulic network topology includes a terminal equipment, a control valve component and a sensor element.

[0014] Specifically, the equipment specification information of the hydraulic terminal equipment in the network is obtained, and the hydraulic network topology is constructed based on this. In the hydraulic network topology, each parallel terminal branch is composed of terminal equipment, control valve components and sensor components. The reasonable configuration and connection of these components can ensure the efficient operation of the entire hydraulic system. By analyzing the common requirements and performance indicators of hydraulic terminal equipment, the configuration of the central hydraulic source can be optimized to adapt to various working conditions and improve the overall reliability and resource utilization of the system. For example, control valve components include solenoid valves, speed regulating valves, pressure reducing valves, etc.

[0015] Step 2: Based on the hydraulic networking topology, the coupling association between functional dimensions and the decoupling stratification within the control dimension are performed to determine the cascade control system.

[0016] Specifically, by analyzing the hydraulic network topology, we first clarify the relationship and dependency between the functional modules based on the coupling relationship between different functional dimensions, and then help identify the interaction mode of communication, control, hydraulic transmission and detection, and lay the foundation for subsequent control optimization. Subsequently, we decouple and layer the control dimension, divide the control system into multiple levels, and gradually decouple the control tasks of each layer from the bottom execution to the high-level management, and finally integrate the structure to form a cascade control system, thereby improving the overall coordination and stability of the system.

[0017] Step three: Determine a networking control mode, wherein the networking control mode includes a master-slave collaboration mode and an equal collaboration mode.

[0018] Specifically, in the process of determining the networking control mode, it is necessary to clarify the type of control mode used, including the master-slave collaboration mode and the equivalent collaboration mode. In the master-slave collaboration mode, one device in the system acts as the master device and the other devices act as slave devices. The master device is responsible for the main control tasks and coordinates the operations of the slave devices. In the equivalent collaboration mode, all devices have equal status and collaborate to process tasks. The devices cooperate with each other and share information to achieve common control of the system. The master-slave collaboration mode and the equivalent collaboration mode are respectively suitable for different system requirements and environments. Through reasonable selection and configuration, the overall performance and collaborative efficiency of the system can be optimized.

[0019] Step 4: Fit the cascade control system and the hydraulic networking topology, perform sample drive training based on the networking control mode, and generate an adaptive configuration module, wherein the adaptive configuration module includes a master-slave configuration branch and an equivalent configuration branch.

[0020] Specifically, by fitting the cascade control system and hydraulic networking topology, and combining the networking control mode for sample-driven training, an adaptive configuration module can be effectively generated, that is, using existing data samples, combined with the master-slave collaboration mode and the equivalent collaboration mode for training, to ensure that the system can achieve the best configuration in different control scenarios. The adaptive configuration module consists of a master-slave configuration branch and an equivalent configuration branch, which correspond to different collaboration modes, ensuring that the system can flexibly switch and self-adjust when encountering various complex operating environments, thereby improving the overall performance and responsiveness of the hydraulic system.

[0021] Step 5: Interactive hydraulic control scenario, identify scenario terminal networking mode, and combine the adaptive configuration module to perform branch matching and hydraulic configuration decision-making to determine the hydraulic configuration strategy.

[0022] Specifically, in the interactive hydraulic control scenario, the networking mode of the terminal devices in the scenario is identified to understand how each terminal device connects and collaborates in the network. Then, combined with the adaptive configuration module, each branch of the hydraulic system is optimally matched with a specific terminal device through branch matching to ensure the effective allocation of hydraulic resources. On this basis, hydraulic configuration decisions are made and finally the hydraulic configuration strategy suitable for the current control scenario is determined, ensuring the flexibility and efficiency of the hydraulic system in different operating environments, and being able to dynamically adjust according to real-time needs to ensure the stable and efficient operation of the system.

[0023] Step 6: The central control system responds to the hydraulic configuration strategy and performs hydraulic network configuration management.

[0024] Specifically, the central control system responds to the hydraulic configuration strategy and starts to configure and manage the entire hydraulic network. According to the guidance of the configuration strategy, the parameters and connection methods of each hydraulic device are automatically adjusted to ensure that hydraulic resources can be efficiently allocated to each terminal device. At the same time, the central control system will monitor the execution of the configuration in real time, and make timely adjustments and optimizations to respond to any emergencies or changes in operating requirements, ensuring that the hydraulic system can continue to maintain a stable and efficient operating state under different operating conditions, and minimize the system's energy loss and potential failures.

[0025] The central hydraulic source configuration method based on the analysis of the network sharing of hydraulic terminal equipment can achieve the technical goal of real-time dynamic adjustment of the control strategy of the hydraulic system, and achieve the technical effect of improving the control accuracy, stability and resource utilization of the equipment.

[0026] Furthermore, the present application also includes: The hydraulic networking topology is traversed, and the risk points of hydraulic networking control are excavated in combination with historical configuration records; the risk points are traversed, and a fault tolerance coefficient based on the risk level is configured, wherein the fault tolerance coefficient is positively correlated with the risk level; based on the fault tolerance coefficient, topology redundancy processing is performed to determine a redundant topology structure; based on the redundant topology structure, the hydraulic networking topology is updated, and physical networking synchronization is performed.

[0027] Specifically, in the process of traversing the hydraulic network topology, combined with previous configuration records, potential risk points can be identified, which are usually prone to failure or performance degradation in the hydraulic system. By analyzing historical data, these risk points can be more accurately located and their impact on the overall operation of the system can be evaluated, thus providing a strong basis for subsequent processing steps.

[0028] Next, by traversing these identified risk points, a fault tolerance coefficient based on the risk level is configured for each risk point. The fault tolerance coefficient indicates the tolerance of the system in the face of risks. Therefore, the higher the risk level, the larger the corresponding fault tolerance coefficient, and the higher the fault tolerance treatment, that is, the higher the proportion of redundant processing. Preferably, when performing redundant design, if there is a structural collision, the one with lower risk equivalent should be avoided first. This positive correlation ensures that high-risk areas receive more redundant protection, thereby improving the safety and stability of the system.

[0029] After obtaining the fault tolerance coefficient, topology redundancy processing is performed, and then a backup or alternative path is introduced in the hydraulic network topology to prevent a single point failure from affecting the entire system. By rationally designing a redundant topology structure, the risk of the system encountering a failure in actual operation can be effectively reduced, ensuring the continuous and stable operation of the system.

[0030] Finally, the original hydraulic network topology is updated according to the designed redundant topology, and the updated topology is synchronized with the actual physical network. The theoretical design is transformed into practical application to ensure that the hydraulic system can operate as expected and has sufficient redundant protection to deal with potential failures.

[0031] By achieving all-round risk management of the hydraulic system, the efficient and safe operation of the system in complex environments can be ensured.

[0032] Furthermore, the present application also includes: For the hydraulic networking topology, coupling association based on functional dimensions is performed to determine the coupling association structure, wherein the functional dimensions include communication dimension, control dimension, hydraulic transmission dimension and detection dimension; the control dimension is decoupled in a hierarchical progressive manner to determine the hierarchical control structure, wherein the control progressive layer includes the sensor actuator layer, process control layer, collaborative control layer, centralized management layer and remote control layer; the coupling association structure and the hierarchical control structure are integrated to determine the cascade control system.

[0033] Specifically, for the hydraulic networking topology, coupling correlation analysis based on the functional dimension can clarify the relationship and dependency between different dimensions. The functional dimension covers communication, control, hydraulic transmission and detection, etc., which represent the key functional modules in the hydraulic system. When performing coupling correlation, identify and determine the interaction mode between these modules in order to better understand the overall operation logic of the system and provide data support for subsequent decoupling and optimization.

[0034] Next, by decoupling the control dimensions in a hierarchical and progressive manner, the independence and role of each layer of the control structure can be clarified. The hierarchical and progressive decoupling method subdivides the control system into the sensor actuator layer, process control layer, collaborative control layer, centralized management layer and remote control layer, and each layer undertakes different control tasks. In the hierarchical structure, the sensor actuator layer is responsible for the underlying execution operation, the process control layer is responsible for the adjustment and optimization of the intermediate links, and the collaborative control layer, centralized management layer and remote control layer are gradually improved, ultimately achieving overall coordination and remote operation of the system.

[0035] Finally, by integrating the coupling association structure with the hierarchical control structure, a cascade control system can be constructed, which not only takes into account the coupling relationship between the various functional modules of the system, but also ensures the coordinated operation of control at different levels, which helps to improve the overall stability and response speed of the system, and also provides a basis for further optimization.

[0036] By forming a cascade control system, it is ensured that the hydraulic system can operate efficiently and stably under complex functional requirements.

[0037] Furthermore, the present application also includes: The master-slave collaboration mode is that in the collaboratively configured terminal devices, the slave device tracks the master device for collaboration; the equivalent collaboration mode is the same-level collaboration in which the collaboratively configured terminal devices track the preset execution signal.

[0038] Specifically, in the master-slave collaborative mode, in the collaboratively configured terminal devices, the slave devices will always follow the instructions of the master device for collaborative operations. The master device is responsible for sending control instructions and monitoring the operating status of the entire system, while the slave device performs corresponding tasks according to the instructions of the master device to ensure the unity and coordination of the system. The master device, as the control center, leads the operation of the entire system, and the slave device is responsible for specific execution to ensure that each task can be completed according to the predetermined plan.

[0039] In the equal collaboration mode, all collaboratively configured terminal devices are at the same level, jointly tracking and responding to preset execution signals, rather than relying on a certain master device. In this mode, each device can independently obtain execution signals and perform task processing, while also cooperating with other devices. Each device has the same control rights and responsibilities, ensuring that each device can cooperate with each other during task execution to complete complex collaborative tasks.

[0040] Based on the system requirements and environment, the most suitable mode can be selected to optimize the overall collaboration efficiency.

[0041] Further, if Figure 2 As shown, this application also includes: Based on the cascade control system and the hydraulic networking topology, the branch architecture of the hydraulic configuration is determined; the branch architecture is twinned to determine the parallel branch architecture; sample data is called and sample division is performed based on the master-slave collaboration mode and the equivalent collaboration mode, and supervised training is performed on the parallel branch architecture to determine the adaptive configuration module.

[0042] Specifically, based on the cascade control system and hydraulic network topology, the branch architecture of the hydraulic configuration is determined, that is, the various branches of the hydraulic system are reasonably divided according to the overall control requirements and topological structure of the system to ensure that the function and role of each branch in the overall system are clear. By dividing the branch architecture, the control path and hydraulic resource allocation of the system can be optimized, and the overall efficiency of the system can be improved.

[0043] Next, twinning means duplicating or mirroring the original branch architecture so that two or more parallel architectures exist at the same time. Twinning the determined branch architecture to create a parallel branch architecture helps to enhance the redundancy and reliability of the system, and also provides a basis for subsequent parallel processing and task sharing.

[0044] Subsequently, the sample data is called and the samples are divided based on the master-slave collaboration mode and the equivalent collaboration mode to supervise the training of the parallel branch architecture. The sample division classifies the data according to different collaboration modes to better train the parallel branch architecture. Through supervised training, the system can gradually learn how to perform adaptive configuration in different modes, thereby optimizing the performance of each branch architecture.

[0045] By determining the adaptive configuration modules, the structural optimization and functional enhancement of the hydraulic system are ensured, so that it can flexibly respond to various operational requirements.

[0046] Furthermore, the present application also includes: Perform hydraulic oil flow resource configuration on the central hydraulic source to determine the total flow of the hydraulic source, wherein the total flow of the hydraulic source is greater than the sum of the rated flows of each terminal device; traverse the hydraulic network topology to determine the branch loss function, wherein the branch loss function is the superposition of each loss point; and make hydraulic configuration decisions based on the total flow of the hydraulic source and the branch loss function as constraints.

[0047] Specifically, when configuring the hydraulic oil flow resources for the central hydraulic source, the total flow of the hydraulic source is determined. The total flow is greater than the sum of the rated flows of each terminal device, ensuring that the hydraulic source can provide sufficient hydraulic oil flow when all devices are running at the same time, avoiding the equipment from not being able to work properly or performance degradation due to insufficient flow.

[0048] Next, traverse the hydraulic network topology to determine the loss function of each branch. The loss function represents the pressure loss caused by factors such as pipeline resistance and valve resistance when the hydraulic oil flows through each branch, that is, the oil flow loss and deposition of the valve. It may also be affected by the flow rate and other factors, and the loss of pipeline layout and material. By superimposing the loss value of each loss point and determining the corresponding loss measurement relationship for the branch circuit corresponding to each terminal, the total loss function of the entire branch can be obtained, which helps to accurately evaluate the energy loss in the hydraulic system and provide data support for subsequent optimization configuration.

[0049] Finally, with the total flow of the hydraulic source and the branch loss function as constraints, the hydraulic configuration decision is made, that is, the supply capacity of the hydraulic source is balanced with the loss of each branch, ensuring that the energy loss in the system is minimized while meeting the needs of each device. Through reasonable configuration decisions, the efficiency and reliability of the hydraulic system can be improved.

[0050] Through hydraulic configuration decisions, it is ensured that the hydraulic system meets the needs of various terminal equipment while minimizing losses and improving the overall efficiency and stability of the system.

[0051] Furthermore, the present application also includes: Taking the total flow of the hydraulic source and the branch loss function as constraints, a hydraulic configuration decision is made to obtain an initialization configuration strategy; the initialization configuration strategy is traversed to perform synchronization timestamp constraints on branch configurations and determine time constraints; a configuration execution mode is determined, and the initialization configuration strategy is performed in combination with the time constraints to determine the hydraulic configuration strategy, wherein the configuration execution mode is a master control based on a PLC and a slave control based on a variable frequency controller.

[0052] Specifically, with the total flow of the hydraulic source and the branch loss function as constraints, hydraulic configuration decisions are made, and the initial configuration strategy is obtained, so as to find a balance between the overall flow of the system and the energy loss of each branch, and preliminarily formulate a hydraulic configuration plan that meets the needs of each device. The initial configuration strategy provides a basis for subsequent optimization and adjustment.

[0053] Next, traverse the initialization configuration strategy and perform synchronization timestamp constraints on branch configurations to determine the time constraints. The synchronization timestamp constraints ensure that when executing the configuration strategy, the operations of each branch can be performed at a precise time point, avoiding uneven traffic distribution or system instability due to time differences. Determining reasonable time constraints can ensure the coordination and synchronization of each branch configuration.

[0054] When determining the configuration execution mode, the initialization configuration strategy is optimized in combination with the determined time constraints, and the hydraulic configuration strategy is finally determined. Among them, the configuration execution mode adopts the master control based on PLC and the slave control mode based on variable frequency controller to ensure the flexibility and efficiency of the system during operation. PLC, as the master control, is responsible for overall scheduling and real-time monitoring, while the variable frequency controller, as the slave control, performs more precise adjustments and responses. The master-slave combination control mode improves the response speed and control accuracy of the system.

[0055] By determining the hydraulic configuration strategy, the coordination, accuracy and efficiency of the hydraulic system in configuration execution are ensured.

[0056] Furthermore, the present application also includes: The hydraulic configuration strategy includes the configuration strategy of the central hydraulic source-terminal equipment and the oil return strategy of the terminal equipment-central hydraulic source; determining the transmission impact vibration threshold, performing over-limit positioning and transmission adjustment on the hydraulic configuration strategy, and determining the calibration hydraulic configuration strategy.

[0057] Specifically, the hydraulic configuration strategy includes the configuration strategy between the central hydraulic source and the terminal equipment, as well as the oil return strategy from the terminal equipment to the central hydraulic source. When designing a hydraulic system, it is necessary not only to consider how to effectively distribute the hydraulic oil from the central hydraulic source to each terminal equipment, but also to plan the path and method for the hydraulic oil to flow back from the terminal equipment to the central hydraulic source, which together determine the overall operating efficiency and reliability of the hydraulic system and ensure smooth and unobstructed hydraulic flow within the system.

[0058] Next, transmission shock and vibration are factors in the hydraulic system that may cause equipment wear or damage. Therefore, a reasonable vibration threshold is set. When the vibration of the system exceeds the set vibration threshold, it is necessary to immediately locate and adjust it to prevent the system from exceeding the safe operating range, thereby effectively avoiding system failures and improving the stability and service life of the hydraulic system.

[0059] Finally, the hydraulic configuration strategy is calibrated, and the hydraulic configuration strategy is adjusted in combination with the transmission shock vibration threshold to optimize system performance in actual operation and ensure that the system can operate stably under various working conditions. Through calibration, the hydraulic system can better adapt to actual operating needs and maintain efficient and safe operation under various load conditions. For example, for the pipeline trend, return oil temperature, filtration, etc. of the hydraulic configuration strategy, excessive impact may cause pipeline damage, or insufficient return oil cooling and unclean filtration, etc., based on this, the transmission control calibration of the execution process is carried out.

[0060] Optimize hydraulic configuration strategy through calibration to ensure efficient, stable and safe operation of the system.
