Technical Field

[0001] The present invention relates to the technical field of fluid pressure control, and particularly to a full-automatic fluid pressure control system and a full-automatic fluid pressure control method. Background Art

[0002] In the current market environment, in the actual application scenarios of fluid pressure load systems, abnormal conditions such as underpressure, overpressure, and unstable pressure frequently occur in fluid pressure load systems. Such pressure anomalies will not only directly trigger alarm prompts at the application level of the load system, but also cause various types of faults in the system, ultimately leading to equipment shutdown, seriously affecting the continuity and stability of the production process.

[0003] However, there is currently no specific, complete and targeted fluid pressure control system on the market, so the above-mentioned faults cannot be accurately and effectively controlled and properly handled, and it is impossible to ensure that the fluid pressure load system products can operate continuously and reliably under a stable pressure state.

[0080] In view of the deficiencies of the existing technologies described above, the applicant, based on rich practical experience and professional knowledge in this field over the years, and in combination with the application of academic theory, actively conducts research and innovation in the hope of creating a technology that can solve the deficiencies in the existing technologies. Through continuous research, design, and repeated sample production and improvement, the present invention with practical value has finally been created.

[0081] Please refer to Figure 1 , an embodiment of the present invention provides a fully automatic fluid pressure control system, including a valve switch control unit 2, a one-way control unit 3, a fluid power source unit 4, a total control unit 5, a pipeline 7, a fluid storage unit 8, a fluid 9, a control circuit 11, and a pressure relief unit 12; wherein,

[0082] The valve switch control unit 2, the one-way control unit 3, and the fluid power source unit 4 are sequentially connected through a pipeline 7 to form a basic channel for the fluid 9 to flow through;

[0083] The valve switch control unit 2 is also connected to a fluid pressure load system 13 through a pipeline 7;

[0084] The fluid power source unit 4 is also connected to the fluid storage unit 8 through a pipeline 7;

[0085] The fluid storage unit 8 stores the fluid 9;

[0086] The pressure relief unit 12 is connected to the pipeline 7 between the valve switch control unit 2 and the one-way control unit 3 through a pipeline 7;

[0087] The total control unit 5 is electrically connected to the valve switch control unit 2, the fluid power source unit 4, the pressure relief unit 12, and the fluid pressure load system 13 respectively through the control circuit 11;

[0088] The total control unit 5 is used to receive a pressure replenishment request from the fluid pressure load system 13, generate a pressure replenishment instruction and send it down; and is used to receive a pressure relief request from the fluid pressure load system 13, generate a pressure relief instruction and send it down;

[0089] The valve switch control unit 2 is used to open or close after receiving the pressure relief instruction or pressure replenishment instruction from the total control unit 5 to achieve precise control of the flow of the fluid 9;

[0090] The one-way control unit 3 is used to prevent the fluid 9 from flowing back reversely, ensuring that the fluid 9 can only flow in a preset direction, thereby maintaining the stability and safety of the system;

[0091] The hydrodynamic power source unit 4 is used to provide power for the flow of the fluid 9 after receiving the pressure replenishment instruction from the total control unit 5, ensuring that the fluid 9 can be smoothly delivered from the fluid storage unit 8;

[0092] The pipeline 7 is used as the passage for the fluid 9 to flow through and undertakes the important task of transporting the fluid 9;

[0093] The fluid storage unit 8 is used as the storage unit for the fluid 9 to ensure that there is an adequate amount of fluid 9 during pressure replenishment;

[0094] The pressure relief unit 12 is used to relieve overpressure of the fluid pressure load system 13 after receiving the pressure relief instruction from the total control unit 5, preventing safety accidents caused by abnormal pressure.

[0095] In summary, in the embodiment of the present invention, by ingeniously integrating multiple key components such as the valve switch control unit 2, the one-way control unit 3, the hydrodynamic power source unit 4, the total control unit 5, the pipeline 7, the fluid storage unit 8, the control circuit 11, and the pressure relief unit 12, a fully automatic fluid pressure control system with perfect functions and excellent performance is constructed. This system can achieve precise and real-time control of the pressure of the fluid pressure load system 13, has the ability to quickly respond to pressure replenishment and relief requests, effectively avoids abnormal conditions such as underpressure, overpressure, and unstable pressure, and thus significantly improves the operation stability and reliability of the fluid pressure load system 13. In addition, the application of this system also helps to greatly reduce equipment failures and downtime caused by abnormal pressure, effectively guarantees the continuity and stability of the production process, and has an important significance that cannot be ignored for improving the level of industrial automation and production efficiency.

[0096] Please refer to again Figure 1 , in an implementation manner of this embodiment, the fully automatic fluid pressure control system further adds a key component, the pressure sensing unit 1, to strengthen the system's ability to accurately sense and intelligently control the fluid pressure.

[0097] The pressure sensing unit 1 is accurately installed at the pipeline position between the valve switch control unit 2 and the fluid pressure load system 13. The selection of this position is to ensure that the pressure sensing unit 1 can capture the pressure changes inside the fluid pressure load system 13 in real time and accurately. At the same time, data transmission and instruction interaction are realized between the pressure sensing unit 1 and the total control unit 5 through a reliable electrical connection method, thereby constructing an efficient and sensitive pressure monitoring and feedback mechanism.

[0098] In terms of function implementation, the pressure sensing unit 1 mainly undertakes two core tasks: firstly, continuously and uninterruptedly monitoring the pressure state of the fluid pressure load system 13; secondly, being able to respond quickly and accurately when abnormal fluctuations in the system pressure are detected. Specifically, when the pressure sensing unit 1 detects that the fluid pressure load system 13 is in an under-pressure state, it will immediately send a pressure supplementation request to the total control unit 5 to prompt that the system needs to increase the fluid pressure to maintain normal operation; conversely, when it detects that the system is in an over-pressure state, it will send a pressure relief request to the total control unit 5 to prevent safety accidents or equipment damage caused by excessive pressure.

[0099] In response to the pressure supplementation request and pressure relief request sent by the pressure sensing unit 1, the total control unit 5 demonstrates a high level of intelligent and automated processing capabilities. Specifically, after receiving the pressure supplementation request from the pressure sensing unit 1, the total control unit 5 will quickly analyze the current state of the system and generate corresponding pressure supplementation instructions, and then send the instructions to the fluid power source unit 4 through the control line 11, instructing it to start and provide sufficient power for the flow of the fluid 9; at the same time, it will also send instructions to the valve switch control unit 2, instructing it to open to allow the fluid to enter the load system. When receiving the pressure relief request, the total control unit 5 will generate a pressure relief instruction and send it to the pressure relief unit 12 and the valve switch control unit 2, instructing the pressure relief unit 12 to perform over-pressure relief operation on the load system, and instructing the valve switch control unit 2 to close to cut off the fluid supply, so as to ensure that the system pressure quickly returns to the safe range.

[0100] In summary, by adding the key component of the pressure sensing unit 1 and constructing an intelligent pressure monitoring and feedback mechanism closely connected to it, the fully automatic fluid pressure control system provided in this embodiment realizes real-time, accurate monitoring and intelligent regulation of the pressure state of the fluid pressure load system 13. This innovative design not only significantly improves the operation stability and reliability of the system, but also effectively reduces the risks of equipment failures and safety accidents caused by abnormal pressure, providing a strong guarantee for the continuity and efficiency of industrial production.

[0101] Please refer to again Figure 1 In an implementation manner of this embodiment, the fully automatic fluid pressure control system further expands its function scope by adding a key module of the remote unit 10 to achieve efficient and stable communication and interaction between the system and the user terminal.

[0102] The remote unit 10 is seamlessly docked with the total control unit 5 through a reliable electrical connection method. At the same time, with the help of advanced communication technology means, a stable and real-time communication connection is established with the user side. This design enables the remote unit 10 to fully play its bridging role. On the one hand, the underpressure state information or overpressure state information of the fluid pressure load system 13 monitored by the total control unit 5 is accurately transmitted to the user side, enabling the user to grasp the system pressure status in real time and providing a strong basis for subsequent decision-making and operations. On the other hand, the remote unit 10 also has the function of receiving instructions from the user side, can capture the pressure replenishment request or pressure relief request sent by the user side in real time, and quickly and accurately forward these requests to the total control unit 5 to trigger the corresponding pressure regulation process.

[0103] In terms of the response mechanism of the total control unit 5, for the pressure replenishment request and pressure relief request forwarded by the remote unit 10, the total control unit 5 demonstrates a high degree of intelligent and automated processing capabilities. Specifically, when the total control unit 5 receives the pressure replenishment request from the remote unit 10, it will immediately start the pressure regulation program, generate the corresponding pressure replenishment instruction, and accurately send the instruction to the fluid power source unit 4 through the control line 11, instructing it to start and provide sufficient power for the flow of the fluid 9; at the same time, it will also send an instruction to the valve switch control unit 2, instructing it to open to allow the fluid to smoothly enter the load system, thereby quickly increasing the system pressure to the normal level.

[0104] When receiving the pressure relief request, the total control unit 5 will quickly generate a pressure relief instruction and send it to the pressure relief unit 12 and the valve switch control unit 2, instructing the pressure relief unit 12 to perform overpressure relief operation on the load system, and instructing the valve switch control unit 2 to close to cut off the fluid supply, ensuring that the system pressure quickly and safely returns to the safe range.

[0105] In summary, by adding the key module of the remote unit 10 and building a remote communication and interaction mechanism closely connected to it, the fully automatic fluid pressure control system provided in this embodiment realizes real-time and efficient communication and interaction between the system and the user side. This innovative design not only greatly improves the intelligent level and user experience of the system, but also enables the user to grasp the system pressure status at any time and remotely initiate a pressure replenishment or pressure relief request according to actual needs, so as to realize remote and accurate regulation of the fluid pressure load system 13. This function expansion not only enhances the flexibility and scalability of the system, but also provides strong support for the remote monitoring and management of industrial production, promoting the further improvement of the industrial automation level.

[0106] Please refer to again Figure 1, in an implementation manner of this embodiment, the fully automatic fluid pressure control system further enhances its functional completeness by adding a crucial basic component, the power supply unit 6, to ensure the stable operation and efficient cooperation of each module of the system.

[0107] The power supply unit 6, as the "heart" of the entire system, is tightly connected to core modules such as the pressure sensing unit 1, the valve switch control unit 2, the fluid power source unit 4, the main control unit 5, the pressure relief unit 12, and the remote unit 10 through precise circuit design and reliable electrical connection methods. This design ensures that the power supply unit 6 can stably and continuously provide the required power support for the entire system, meeting the electrical energy requirements of each module during operation.

[0108] Specifically, the power provided by the power supply unit 6 not only drives the pressure sensing unit 1 to accurately monitor the pressure state of the fluid pressure load system 13, but also ensures that the valve switch control unit 2 can quickly and accurately open or close after receiving an instruction to achieve precise control of fluid flow. At the same time, the power supply unit 6 also provides sufficient electrical energy for the fluid power source unit 4, enabling it to continuously and stably provide power for the flow of the fluid 9 to meet the pressure requirements of the load system. In addition, with the power support of the power supply unit 6, the main control unit 5 can efficiently process signals and instructions from each module to achieve intelligent regulation and collaborative management of the entire system.

[0109] In the case of the pressure relief unit 12 and the remote unit 10, the power supply unit 6 also plays an indispensable role. It ensures that the pressure relief unit 12 can quickly and reliably perform overpressure relief operations on the fluid pressure load system 13 after receiving a pressure relief instruction, preventing safety accidents caused by excessive pressure. At the same time, with the power guarantee of the power supply unit 6, the remote unit 10 can stably and real-time communicate and interact with the user side to achieve remote monitoring and regulation of the system pressure state.

[0110] In summary, by adding the key component of the power supply unit 6 and building a tightly connected power supply system, the fully automatic fluid pressure control system provided in this embodiment realizes stable and continuous power support for each module. This innovative design not only greatly improves the operation stability and reliability of the system, but also provides strong guarantee for the collaborative work of each module, promoting the wide application and in-depth development of the fully automatic fluid pressure control system in industrial production.

[0111] In an implementation manner of this embodiment, the fluid 9 is a liquid or a gas.

[0112] Specifically, when the system was designed, the diverse needs of fluid media in different industrial scenarios were fully considered. Therefore, in the selection of fluid 9, it can be adapted to various liquid media, such as water, oils, chemical solvents, etc., to meet the industrial application requirements of liquid transportation, pressure regulation, flow control, etc. At the same time, it can also flexibly respond to the regulation requirements of gas media, including but not limited to air, nitrogen, oxygen, inert gases, etc., to support complex process processes such as gas compression, vacuum generation, gas mixing and distribution.

[0113] This design feature not only demonstrates the high versatility and wide applicability of the fluid pressure control system in this embodiment, but also reflects the system designer's profound understanding and accurate grasp of the actual needs of industrial production. By supporting the regulation of two fluid media, liquid and gas, the system can easily integrate into and serve multiple industrial fields such as petrochemical, energy and power, food and beverage, biopharmaceuticals, environmental protection engineering, etc., providing efficient, stable and reliable solutions for fluid pressure control and transmission in different industries.

[0114] In addition, in view of the differences in physical properties, flow characteristics and regulation requirements between liquids and gases, the fluid pressure control system in this embodiment also incorporates advanced intelligent control algorithms and adaptive adjustment technologies, which can automatically adjust system parameters and control strategies according to the real-time state of the fluid medium and process requirements to achieve precise control and stable transmission of fluid pressure. This innovative design not only improves the intelligent level and automation degree of the system, but also further enhances the adaptability and flexibility of the system in different industrial scenarios.

[0115] Although terms such as fluid and power supply unit are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

In addition, it also helps to reduce equipment failures and downtime caused by abnormal pressure, ensure the continuity of the production process, and is of great significance for improving the level of industrial automation and production efficiency.

[0117] Embodiment 2

[0118] Please refer to Figure 2 , Figure 2FIG. 0 is a schematic flowchart of a fully automatic fluid pressure control method provided in the first embodiment of the present invention. This method is applied to the fully automatic fluid pressure control system provided in the first embodiment above. The method specifically includes the following steps:

[0119] S101. When the fluid pressure load system 13 detects an underpressure state, it sends a pressure replenishment request to the overall control unit 5.

[0120] It should be noted that in the fully automatic fluid pressure control system, the fluid pressure load system 13 plays an important role in performing specific process tasks (such as driving equipment operation, maintaining a specific process environment, etc.). A certain pressure value needs to be maintained inside it to work properly. Usually, a dedicated pressure detection device is set in the system (which can be integrated in the fluid pressure load system 13 or connected to the system as an independent unit). This device can monitor the pressure value inside the fluid pressure load system 13 in real time and accurately. Once the detected pressure value is lower than the preset normal working range (i.e., the underpressure state), subsequent actions will be triggered.

[0121] After determining that the fluid pressure load system 13 is in an underpressure state, in order to restore its normal working pressure, the system needs to take pressure replenishment measures. At this time, the fluid pressure load system 13 will send a pressure replenishment request signal to the overall control unit 5 through a pre-set communication protocol and interface. This request signal contains key information about the underpressure situation, such as the current pressure value, the degree of underpressure, etc., so that the overall control unit 5 can accurately understand the situation and make corresponding decisions.

[0122] This step is the trigger point of the entire pressure replenishment process. It enables the system to timely sense the pressure abnormality and coordinate the subsequent pressure replenishment operations through the overall control unit 5, ensuring that the fluid pressure load system 13 can quickly return to the normal working state and avoiding problems such as process interruption and equipment damage caused by underpressure.

[0123] S102. After receiving the pressure replenishment request, the overall control unit 5 generates a pressure replenishment instruction to control the fluid power source 4 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid storage unit 8 along the pipeline 7 through the one-way control unit 3 and is delivered to the fluid pressure load system 13 to replenish the pressure of the fluid pressure load system 13.

[0124] It should be noted that the total control unit 5, as the core control center of the entire system, has powerful data processing and decision-making capabilities. After receiving the pressure replenishment request sent by the fluid pressure load system 13, the total control unit 5 will generate corresponding pressure replenishment instructions according to the preset control logic and algorithms, combined with the current overall operating state of the system (such as the pressure conditions of other load systems, the remaining amount of the fluid storage unit 8, etc.). This instruction contains specific operation requirements, such as the output power of the fluid power source 4, the opening degree of the valve switch control unit 2, and other parameters.

[0125] The total control unit 5 sends the generated pressure replenishment instructions to the fluid power source 4 and the valve switch control unit 2 respectively through a reliable communication line. After receiving the instruction, the fluid power source 4 will start and adjust to the appropriate operating state according to the instruction requirements, providing sufficient power for the flow of the fluid. The valve switch control unit 2 will open the corresponding valve according to the instruction, enabling the fluid to flow smoothly.

[0126] Under the coordinated action of the fluid power source 4 and the valve switch control unit 2, the fluid 9 stored in the fluid storage unit 8 starts to flow. The fluid flows along the pre-laid pipeline 7, passing through the one-way control unit 3 in sequence (the function of the one-way control unit 3 is to ensure that the fluid can only flow in the predetermined direction and prevent the fluid from flowing back), and finally is transported to the fluid pressure load system 13. As the fluid is continuously input, the pressure in the fluid pressure load system 13 gradually increases, thereby achieving the purpose of pressure replenishment.

[0127] This step is the core link of the pressure replenishment process. Through the precise control of the total control unit 5, the coordinated operation of the fluid power source 4, the valve switch control unit 2, and the fluid transportation path is realized, ensuring that the fluid can be accurately and efficiently transported to the fluid pressure load system 13 for pressure replenishment, enabling the system to quickly return to the normal working pressure.

[0128] S103. When the fluid pressure load system 13 detects that the pressure value is met, it notifies the total control unit 5, and the total control unit 5 issues an instruction to turn off the fluid power source 4 and the valve switch control unit 2.

[0129] It should be noted that during the pressure replenishment process, the fluid pressure load system 13 continuously monitors its own pressure value. When the pressure value reaches the preset normal working range (i.e., the pressure value is met), the system determines that the pressure replenishment operation has been completed, and at this time, further pressure replenishment needs to be stopped.

[0130] In order to coordinate the operation of the entire system, the fluid pressure load system 13 will promptly notify the total control unit 5 of the information that the pressure has met the requirements. The notification method is usually also carried out through the pre-set communication protocol and interface to ensure the accurate transmission of information.

[0131] After receiving the notification from the fluid pressure load system 13, the total control unit 5 generates a shutdown instruction according to the operation strategy and control logic of the system, and sends it to the fluid power source 4 and the valve switch control unit 2 respectively. After receiving the shutdown instruction, the fluid power source 4 gradually reduces the output power until it stops operating; the valve switch control unit 2 closes the corresponding valve to cut off the fluid delivery path.

[0132] This step is the end link of the pressure replenishment process. It ensures that after the fluid pressure load system 13 reaches the normal working pressure, the pressure replenishment operation can be stopped in time, avoiding problems such as excessive pressure caused by over-pressure replenishment, saving energy, and improving the operation efficiency and stability of the system. Through the unified coordination of the total control unit 5, the precise control and orderly end of the pressure replenishment process are achieved.

[0133] Please refer to Figure 3 , the full-automatic fluid pressure control method further includes the following steps:

[0134] S201. When the fluid pressure load system 13 detects that it is in an over-pressure state, it sends a pressure relief request to the total control unit 5.

[0135] It should be noted that after it is determined that the fluid pressure load system 13 is in an over-pressure state, in order to avoid adverse consequences such as equipment damage and safety accidents caused by excessive pressure, the system needs to take pressure relief measures in time. At this time, the fluid pressure load system 13 will send a pressure relief request signal to the total control unit 5 through a pre-set communication protocol and interface. This request signal contains key information about the over-pressure situation, such as the current pressure value and the degree of over-pressure, so that the total control unit 5 can accurately understand the situation and make corresponding decisions.

[0136] This step is the trigger point of the entire pressure relief process. It enables the system to timely sense the pressure abnormality and coordinate the subsequent pressure relief operations through the total control unit 5, ensuring that the fluid pressure load system 13 can quickly return to the safe pressure range and guaranteeing the safe and stable operation of the system.

[0137] S202. After receiving the pressure relief request, the total control unit 5 generates a pressure relief instruction to control the pressure relief unit 12 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid pressure load system 13 along the pipeline 7 through the valve switch control unit 2 and is delivered to the pressure relief unit 12 to relieve the pressure of the fluid pressure load system 13.

[0138] It should be noted that the total control unit 5, as the core control center of the system, has powerful data processing and decision-making capabilities. When receiving the pressure relief request sent by the fluid pressure load system 13, the total control unit 5 will generate corresponding pressure relief instructions according to the preset control logic and algorithms, combined with the current overall operating state of the system (such as the pressure conditions of other load systems, the working state of the pressure relief unit 12, etc.). This instruction contains specific operation requirements, such as the pressure relief rate of the pressure relief unit 12, the opening degree of the valve switch control unit 2, and other parameters.

[0139] The total control unit 5 sends the generated pressure relief instructions to the pressure relief unit 12 and the valve switch control unit 2 respectively through reliable communication lines. After receiving the instruction, the pressure relief unit 12 will start and adjust to the appropriate pressure relief state according to the instruction requirements to release the fluid pressure. The valve switch control unit 2 will open the corresponding valve according to the instruction to enable the fluid to flow out of the fluid pressure load system 13 smoothly.

[0140] Under the coordinated action of the pressure relief unit 12 and the valve switch control unit 2, the excessive fluid 9 in the fluid pressure load system 13 starts to flow. The fluid flows along the pre-laid pipeline 7, passes through the valve switch control unit 2 in sequence, and finally is transported to the pressure relief unit 12. As the fluid continuously flows out, the pressure in the fluid pressure load system 13 gradually decreases, thus achieving the purpose of pressure relief.

[0141] This step is the core link of the pressure relief process. Through the precise control of the total control unit 5, the coordinated operation of the pressure relief unit 12, the valve switch control unit 2, and the fluid delivery path is realized, ensuring that the fluid can flow out of the fluid pressure load system 13 accurately and efficiently for pressure relief, so that the system can quickly return to the safe pressure range.

[0142] S203. When the fluid pressure load system 13 detects that the pressure relief limit is met, it notifies the total control unit 5, and the total control unit 5 issues an instruction to close the pressure relief unit 12 and the valve switch control unit 2.

[0143] It should be noted that during the pressure relief process, the fluid pressure load system 13 continuously monitors its own pressure value. When the pressure value drops to the preset safety lower limit (i.e., the pressure relief limit is met), the system determines that the pressure relief operation has been completed, and at this time, further pressure relief needs to be stopped.

[0144] In order to coordinate the operation of the entire system, the fluid pressure load system 13 will promptly notify the total control unit 5 of the information that the pressure has met the requirements. The notification method is usually also through the pre-set communication protocol and interface to ensure the accurate transmission of information.

[0145] After receiving the notification from the fluid pressure load system 13, the total control unit 5 generates a shutdown instruction according to the operation strategy and control logic of the system, and sends it to the pressure relief unit 12 and the valve switch control unit 2 respectively. After receiving the shutdown instruction, the pressure relief unit 12 stops the pressure relief operation; the valve switch control unit 2 closes the corresponding valve to cut off the fluid delivery path.

[0146] This step is the end link of the pressure relief process. It ensures that after the fluid pressure load system 13 reaches the safe pressure range, the pressure relief operation can be stopped in time, avoiding the problem of too low pressure caused by excessive pressure relief. At the same time, it also saves energy, improves the operation efficiency and stability of the system. Through the unified coordination of the total control unit 5, the precise control and orderly end of the pressure relief process are achieved.

[0147] Please refer to Figure 4 , the full-automatic fluid pressure control method further includes the following steps:

[0148] S301. When the pressure sensing unit 1 detects that the fluid pressure load system 13 is in an underpressure state, a pressure replenishment request is sent to the total control unit 5.

[0149] It should be noted that the pressure sensing unit 1 is a device specially used to monitor the pressure situation in the fluid pressure load system 13 in real time. It has the characteristics of high precision and high sensitivity, can accurately sense the pressure change of the fluid in the system, and convert the pressure signal into an electrical signal.

[0150] The pressure sensing unit 1 judges whether the fluid pressure load system 13 is in an underpressure state according to a preset pressure threshold. When the detected pressure value is lower than the set lower limit value, it is determined that the system is in an underpressure state.

[0151] Once it is determined that the system is underpressure, the pressure sensing unit 1 will send a pressure replenishment request signal to the total control unit 5 through a specific communication interface and protocol. This request signal contains information related to the underpressure, such as the current pressure value, the duration of underpressure, etc., so that the total control unit 5 can fully understand the system state.

[0152] This step, as the starting point of the pressure replenishment process, through the real-time monitoring and accurate judgment of the pressure sensing unit 1, can timely detect the underpressure problem of the fluid pressure load system 13 and quickly notify the total control unit 5, providing a trigger condition for the subsequent pressure replenishment operation, ensuring that the system can quickly restore normal pressure and maintain stable operation.

[0153] S302. After receiving the pressure replenishment request, the general control unit 5 generates a pressure replenishment instruction to control the fluid power source 4 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid storage unit 8 along the pipeline 7 through the one-way control unit 3 and is delivered to the fluid pressure load system 13 to replenish the pressure of the fluid pressure load system 13.

[0154] S303. When the pressure sensing unit 1 detects that the fluid pressure load system 13 meets the pressure value, it notifies the general control unit 5, and the general control unit 5 issues an instruction to turn off the fluid power source 4 and the valve switch control unit 2.

[0155] It should be noted that during the pressure replenishment process, the pressure sensing unit 1 continuously monitors the pressure in the fluid pressure load system 13. When the detected pressure value reaches the preset normal working pressure range (i.e., meets the pressure value), the pressure sensing unit 1 determines that the pressure replenishment operation has been completed.

[0156] To coordinate the operation of the entire system, the pressure sensing unit 1 will promptly notify the general control unit 5 of the information that the pressure has met the requirements. The notification method is usually through the communication interface and protocol with the general control unit 5 to ensure the accurate transmission of information.

[0157] After receiving the notification from the pressure sensing unit 1, the general control unit 5 generates a shutdown instruction according to the operation strategy and control logic of the system and sends it to the fluid power source 4 and the valve switch control unit 2 respectively. After receiving the shutdown instruction, the fluid power source 4 gradually reduces the output power until it stops running; the valve switch control unit 2 closes the corresponding valve to cut off the fluid delivery path.

[0158] This step is the end link of the pressure replenishment process. It ensures that after the fluid pressure load system 13 reaches the normal working pressure, the pressure replenishment operation can be stopped in time, avoiding the problem of excessive pressure caused by overpressure replenishment. At the same time, it also saves energy, improves the operation efficiency and stability of the system. Through the unified coordination of the general control unit 5, the accurate control and orderly end of the pressure replenishment process are achieved, enabling the system to stably maintain operation within the normal working pressure range.

[0159] Please refer to Figure 5 , the full-automatic fluid pressure control method further includes the following steps:

[0160] S401. When the pressure sensing unit 1 detects that the fluid pressure load system 13 is in an overpressure state, it issues a pressure relief request to the general control unit 5.

[0161] It should be noted that the system has pre-set the normal operating pressure range of the fluid pressure load system 13. When the pressure value detected by the pressure sensing unit 1 exceeds the upper limit of this range, it is determined that the system is in an overpressure state. This overpressure may be caused by internal system failures, external pressure shocks, abnormal fluid supply, or other reasons.

[0162] Once it is determined that the system is overpressured, the pressure sensing unit 1 will send a pressure relief request signal to the total control unit 5 through a specific communication interface and protocol. This request signal contains relevant information about the overpressure, such as the current pressure value, the degree of overpressure, and the duration of overpressure, so that the total control unit 5 can comprehensively understand the system state and make corresponding decisions.

[0163] This step serves as the trigger point for the pressure relief process. Through the real-time monitoring and accurate judgment of the pressure sensing unit 1, the overpressure problem of the fluid pressure load system 13 can be detected in a timely manner, and the total control unit 5 can be notified quickly, providing a start signal for the subsequent pressure relief operation to ensure that the system can take timely measures to avoid equipment damage or safety accidents caused by overpressure.

[0164] S402. After receiving the pressure relief request, the total control unit 5 generates a pressure relief instruction to control the pressure relief unit 12 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid pressure load system 13 along the pipeline 7 through the valve switch control unit 2 and is delivered to the pressure relief unit 12 to relieve the pressure of the fluid pressure load system 13.

[0165] S403. When the pressure sensing unit 1 monitors that the fluid pressure load system 13 meets the pressure relief limit value, it notifies the total control unit 5, and the total control unit 5 issues an instruction to close the pressure relief unit 12 and the valve switch control unit 2.

[0166] It should be noted that during the pressure relief process, the pressure sensing unit 1 continuously monitors the pressure inside the fluid pressure load system 13. When the detected pressure value drops to the preset safe lower limit (i.e., meets the pressure relief limit value), the pressure sensing unit 1 determines that the pressure relief operation has been completed. This pressure relief limit value is set according to the safety operation requirements of the system to ensure that the system can operate stably within a suitable pressure range after pressure relief.

[0167] To coordinate the operation of the entire system, the pressure sensing unit 1 will promptly notify the total control unit 5 of the information that the pressure has met the requirements. The notification method is usually through the communication interface and protocol with the total control unit 5 to ensure the accurate transmission of information.

[0168] After receiving the notification from the pressure sensing unit 1, the total control unit 5 generates a shutdown instruction according to the operating strategy and control logic of the system, and sends it to the pressure relief unit 12 and the valve switch control unit 2 respectively. After receiving the shutdown instruction, the pressure relief unit 12 stops the pressure relief operation; the valve switch control unit 2 closes the corresponding valve to cut off the fluid delivery path.

[0169] This step is the end link of the pressure relief process. It ensures that after the fluid pressure load system 13 reaches the safe pressure range, the pressure relief operation can be stopped in time, avoiding the problem of too low pressure caused by excessive pressure relief. At the same time, it also saves energy, improves the operating efficiency and stability of the system. Through the unified coordination of the total control unit 5, the precise control and orderly end of the pressure relief process are achieved, enabling the system to stably operate within the normal working pressure range.

[0170] Please refer to Figure 6 , the full-automatic fluid pressure control method further includes the following steps:

[0171] S501. When the fluid pressure load system 13 detects an underpressure state, or the pressure sensing unit 1 detects that the fluid pressure load system 13 is in an underpressure state, a pressure replenishment request is sent to the total control unit 5.

[0172] It should be noted that whether the fluid pressure load system 13 detects underpressure or the pressure sensing unit 1 detects underpressure, a pressure relief (pressure replenishment) request will be sent to the total control unit 5. This dual-trigger mechanism improves the accuracy and reliability of the system's judgment of the underpressure state, avoiding misjudgment or missed judgment situations that may occur due to a single detection method.

[0173] Through the dual detection mechanism, the underpressure condition of the fluid pressure load system 13 can be captured more comprehensively and accurately, and a pressure replenishment request is sent to the total control unit 5 in a timely manner, providing an accurate trigger signal for subsequent pressure replenishment operations, ensuring that the system can respond quickly when underpressure and maintain the normal operation of the system.

[0174] S502. The total control unit 5 sends the underpressure state information of the fluid pressure load system 13 to the user terminal.

[0175] It should be noted that after receiving the pressure replenishment request, the total control unit 5 will organize and package the underpressure state information of the fluid pressure load system 13, and then send this information to the user terminal through a specific communication protocol and network connection. These information may include details such as the degree of underpressure, duration, and current pressure value.

[0176] The client can be various devices with communication functions, such as computers, mobile phones, etc. The user can receive and view this undervoltage status information through the application program or web interface installed on the client to understand the operation of the system.

[0177] This step realizes the information interaction between the system and the user, enabling the user to timely understand the undervoltage condition of the fluid pressure load system 13 and enhancing the user's monitoring and management capabilities of the system. The user can make corresponding decisions based on this information, such as whether manual intervention is required or system parameters need to be adjusted, etc.

[0178] S503. Receive the pressure replenishment request from the client, generate a pressure replenishment instruction to control the fluid power source 4 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid storage unit 8 along the pipeline 7 through the one-way control unit 3 and is delivered to the fluid pressure load system 13 to replenish the pressure of the fluid pressure load system 13.

[0179] It should be noted that after the total control unit 5 sends the undervoltage status information to the client, it will be in a state of waiting for the client's feedback. When receiving the pressure replenishment request sent by the client, the total control unit 5 will generate an accurate pressure replenishment instruction according to the preset control strategy and algorithm, combined with other operating parameters of the current system.

[0180] After the pressure replenishment instruction is generated, the total control unit 5 will send the instruction to the fluid power source 4 and the valve switch control unit 2 respectively through a reliable communication line. After receiving the instruction, the fluid power source 4 will adjust its own operating state to provide sufficient power to pump out the fluid 9 from the fluid storage unit 8; the valve switch control unit 2 will open the corresponding valve according to the instruction to enable the fluid to pass through smoothly.

[0181] Under the coordinated action of the fluid power source 4 and the valve switch control unit 2, the fluid 9 starts from the fluid storage unit 8 and flows along the pre-laid pipeline 7. During the flowing process, the fluid passes through the one-way control unit 3 to ensure that the fluid can only flow in the predetermined direction and prevent the fluid from flowing back. Finally, the fluid 9 is delivered to the fluid pressure load system 13. As the fluid is continuously input, the pressure in the system gradually increases to achieve the purpose of pressure replenishment.

[0182] This step gives the user direct control over the pressure replenishment operation of the system. The user can decide whether to replenish the pressure according to the actual needs and system conditions. At the same time, through the precise control of the total control unit 5, the coordinated work of the fluid power source 4, the valve switch control unit 2 and the fluid delivery path is realized, ensuring that the fluid can be accurately and efficiently delivered to the fluid pressure load system 13 for pressure replenishment, and improving the flexibility and operability of the system.

[0183] S504. When the fluid pressure load system 13 detects that the pressure value is met, or the pressure sensing unit 1 detects that the fluid pressure load system 13 meets the pressure value, it notifies the master control unit 5, and the master control unit 5 issues an instruction to close the fluid power source 4 and the valve switch control unit 2.

[0184] Please refer to Figure 7 , the full-automatic fluid pressure control method further includes the following steps:

[0185] S601. When the fluid pressure load system 13 detects an overpressure state, or the pressure sensing unit 1 detects that the fluid pressure load system 13 is in an overpressure state, it issues a pressure relief request to the master control unit 5.

[0186] It should be noted that

[0187] Once any detection method determines that the system is in an overpressure state, a pressure relief request will be issued to the master control unit 5. This ensures that the system can be promptly detected when overpressure occurs, providing an accurate trigger signal for subsequent pressure relief operations.

[0188] Through the dual detection mechanism, the overpressure condition of the fluid pressure load system 13 can be quickly and accurately captured, and a pressure relief request is sent to the master control unit 5 in a timely manner, ensuring that the system can respond promptly when overpressure occurs and preventing equipment damage or safety accidents caused by overpressure.

[0189] S602. The master control unit 5 sends the overpressure state information of the fluid pressure load system 13 to the user terminal.

[0190] It should be noted that after receiving the pressure relief request, the master control unit 5 will sort out the overpressure state information of the fluid pressure load system 13, including the overpressure degree, duration, current pressure value, etc. Then, through a specific communication protocol and network connection, this information is sent to the user terminal.

[0191] This step realizes the information interaction between the system and the user, enabling the user to promptly master the overpressure condition of the fluid pressure load system 13 and enhancing the user's monitoring and management capabilities of the system. The user can decide whether to perform manual intervention or adjust system parameters based on this information.

[0192] S603. Receive the pressure relief request from the user terminal, generate a pressure relief instruction to control the pressure relief unit 12 and the valve switch control unit 2 to start working. The fluid 9 flows from the fluid pressure load system 13 along the pipeline 7 through the valve switch control unit 2 and is delivered to the pressure relief unit 12 to relieve the pressure of the fluid pressure load system 13.

[0193] It should be noted that after the total control unit 5 sends the overvoltage status information to the user side, it waits for the feedback from the user side. When receiving the pressure relief request sent by the user side, the total control unit 5 generates an accurate pressure relief instruction according to the preset control strategy and algorithm, in combination with other operating parameters of the system.

[0194] After the pressure relief instruction is generated, the total control unit 5 sends the instruction to the pressure relief unit 12 and the valve switch control unit 2 respectively through a reliable communication line. After receiving the instruction, the pressure relief unit 12 adjusts its own state to prepare for pressure relief; the valve switch control unit 2 opens the corresponding valve according to the instruction to enable the fluid to pass through smoothly.

[0195] Under the collaborative action of the pressure relief unit 12 and the valve switch control unit 2, the fluid 9 starts from the fluid pressure load system 13, flows along the pipeline 7, and is transported to the pressure relief unit 12 after passing through the valve switch control unit 2. As the fluid continuously flows out, the pressure in the fluid pressure load system 13 gradually decreases, achieving the purpose of pressure relief.

[0196] This step gives the user direct control over the system's pressure relief operation, and the user can decide whether to perform pressure relief according to actual needs and the system status. At the same time, through the precise control of the total control unit 5, the collaborative work of the pressure relief unit 12, the valve switch control unit 2, and the fluid delivery path is realized, ensuring that the fluid can be accurately and efficiently transported to the pressure relief unit 12 for pressure relief, improving the flexibility and operability of the system.

[0197] S604. When the fluid pressure load system 13 detects that the pressure relief limit is met, or the pressure sensing unit 1 detects that the fluid pressure load system 13 meets the pressure relief limit, it notifies the total control unit 5, and the total control unit 5 issues an instruction to close the pressure relief unit 12 and the valve switch control unit 2.

[0198] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby.
