In other words, artificial intelligence is a comprehensive technology in computer science that attempts to understand the essence of intelligence and produce a new kind of intelligent machine that can react in a way similar to human intelligence. Artificial intelligence is the study of the design principles and implementation methods of various intelligent machines, enabling machines to have the functions of perception, reasoning, and decision-making.

[0022] Computer vision (CV) is a science that studies how to enable machines to "see." More specifically, it refers to machine vision, which uses cameras and computers to replace human eyes in recognizing and measuring targets, and then performs image processing to create images more suitable for human observation or transmission to instruments.

[0032] In addition, such as Figure 1 As shown, the electronic pump intelligent variable frequency speed control system may also include a memory 200 for storing data, such as image data and location information.

[0033] It should be noted that, Figure 1 The schematic diagram of the electronic pump intelligent variable frequency speed control system shown is merely an example. The electronic pump intelligent variable frequency speed control system and scenario described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application.

[0034] This invention discloses an intelligent variable frequency speed control system and method for electronic pumps, which helps to overcome the limitations of response speed and accuracy, improve the intelligent speed control accuracy of electronic pumps, and achieve a dual improvement in energy efficiency and stability. These will be described in detail below.

[0035] Example 1 Please see Figure 2 , Figure 2 This is a flowchart illustrating an intelligent variable frequency speed control method for an electronic pump disclosed in an embodiment of the present invention. Figure 2 The described intelligent variable frequency speed control method for electronic pumps is applied in management systems, such as local servers or cloud servers for management, and this embodiment of the invention is not limited thereto. Figure 2 As shown, the intelligent variable frequency speed control method for the electronic pump may include the following operations: 101. Obtain information about the target controlled object and information collected by the system.

[0036] In this embodiment of the invention, the information collected by the system includes information collected on the controlled object and information collected on the control signal.

[0037] 102. Analyze and process the target control object information and system acquisition information to obtain basic analysis signal information and target control mode information.

[0038] In this embodiment of the invention, the basic analysis signal information includes first analysis signal information and second analysis signal information.

[0039] 103. Analyze and process the basic analysis signal information and control signal acquisition information using the target control method information to obtain the target control signal information.

[0040] It should be noted that the aforementioned target control signal information is used to adjust the speed of the electronic pump, and this embodiment of the invention does not limit this.

[0041] It should be noted that the above-mentioned target control object information represents the desired control target of the control object of the actuator, such as the desired displacement of the hydraulic cylinder, and the embodiments of the present invention are not limited thereto.

[0042] It should be noted that the information collected by the controlled object described above represents the actual control status of the controlled object of the actuator, such as the actual displacement of the hydraulic cylinder, and this embodiment of the present invention does not limit it.

[0043] It should be noted that the above-mentioned control signal acquisition information represents the control signal before signal amplification in the previous control cycle. It is used to correct the signal in the current control cycle to improve control accuracy. This embodiment of the invention does not limit this.

[0044] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0045] In an optional embodiment, the above-described analysis and processing of the target control object information and system acquisition information to obtain basic analysis signal information and target control method information includes: The target control object information and the control object acquisition information in the system acquisition information are weighted and summed to obtain the first analysis signal information in the basic analysis signal information. The first analytical signal information is differentiated to obtain the second analytical signal information from the basic analytical signal information; Based on the first analysis signal information in the basic analysis signal information, the target control mode information is determined.

[0046] It should be noted that the above-mentioned weighted summation of the target control object information and the control object acquisition information in the system acquisition information is to subtract the value corresponding to the control object acquisition information in the system acquisition information from the value corresponding to the target control object information, so as to obtain the difference between the expected control target and the actual displacement of the hydraulic actuator, thereby facilitating the adjustment of the speed of the electronic pump. This embodiment of the present invention does not limit this.

[0047] It should be noted that the above-mentioned differential processing of the first analysis signal information is to perform differential calculation on the first analysis signal information and the historical analysis signal information to obtain the second analysis signal information of the displacement difference corresponding to the current period. This embodiment of the invention does not limit this.

[0048] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0049] In another optional embodiment, the target control method information is determined based on the first analysis signal information in the basic analysis signal information, including: Obtain the control threshold; Determine whether the signal value corresponding to the first analysis signal information in the basic analysis signal information is greater than or equal to the control threshold, and obtain the first judgment result; When the first judgment result is yes, the first control mode is determined to be the target control mode information; If the first judgment result is negative, the second control method is determined to be the target control method information.

[0050] It should be noted that the above-mentioned target control method information includes a first control method and a second control method. Furthermore, the reason for adopting two control methods in this application is that the first control method is used when the difference between the expected displacement and the actual displacement is relatively large, while the second control method is used when the displacement difference is small. This is to use a large rotation speed when using the first control method to quickly move the actuator to reduce the gap between the actual displacement and the expected displacement as soon as possible. Then, when approaching the expected displacement, the second control method is switched to ensure the accuracy of the end control, thereby achieving an effective combination of high response speed and high precision, improving the control response speed and precision of the system, and effectively improving the system control performance. This embodiment of the invention is not limited.

[0051] It should be noted that the aforementioned control threshold can be set by the user or obtained by analyzing historical control thresholds using a large model. Its value ranges from 0 to the displacement stroke of the actuator, and this embodiment of the invention does not impose any limitations. Furthermore, the direct comparison between the signal value corresponding to the first analysis signal information and the control threshold is mainly based on the consideration that displacement is the final control target. Therefore, the direct difference between the expected displacement and the actual displacement is used for comparison. This not only directly reflects the actual control needs of the control target but also provides a simple judgment method, thereby achieving efficient and accurate selection of control methods and improving response speed. The control accuracy is guaranteed by the specific control method, realizing the dual control effectiveness of phased decision-making and phased control, which can effectively guarantee the system response speed and control accuracy. This embodiment of the invention does not impose any limitations.

[0052] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0053] In another optional embodiment, the target control method information is used to analyze and process the basic analysis signal information and the control signal acquisition information to obtain the target control signal information, including: When the target control mode information is the first control mode, the basic analysis signal information is inferred and analyzed to obtain the target control signal information; When the target control mode information is the second control mode, the target control signal information is determined based on the basic analysis signal information and the control signal acquisition information.

[0054] It should be noted that the first control method described above is used for rapid adjustment of the actuator to improve the response speed of the entire control process, shorten the response time from the actual displacement of the actuator to the desired displacement, and improve control efficiency. Furthermore, to avoid oscillations that may occur during the rapid control process from the actual displacement to the desired displacement (oscillations can cause repeated impacts on the actuator, reducing control accuracy, which is one of the difficulties in current high-precision control), the system switches to the second control method at the end, i.e., adopts a more refined control process. Since the first control method used in the first stage has already rapidly shortened the required control displacement, only high-precision control of small displacements is required in the second stage. This ensures control accuracy while also minimizing the time consumed, thus balancing response speed and control accuracy. This achieves high-precision and fast-response intelligent control of the electronic pump speed regulation control. This embodiment of the invention is not limited to this.

[0055] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0056] In another optional embodiment, reasoning analysis is performed on the basic analysis signal information to obtain target control signal information, including: Obtain fuzzy reasoning information; Fuzzy inference information is used to perform fuzzy inference processing on the basic analysis signal information to obtain the first inference signal information; The first inference signal information is corrected to obtain the target control signal information.

[0057] It should be noted that the above-mentioned reasoning analysis of the basic analysis signal information to obtain the target control signal information is achieved by using fuzzy inference information to quickly fuzzily derive the first and second analysis signals in the input basic analysis signal information. This allows for rapid output of the control signal based on rules derived from historical data, ensuring the effectiveness of the control signal generation. Furthermore, the efficiency of the fuzzy inference process guarantees the response speed. The fuzzy inference information can be constructed based on a 7-level fuzzy subset, and its function can be a Gaussian function. The constructed fuzzy subset can be negative large, negative medium, negative small, zero, positive small, positive medium, and positive large. The universe of discourse for the two input signals can be [-0.5, 0.5], [-0.06, 0.06], and [-1.6, 1.6]. This embodiment of the invention does not impose any limitations on these dimensions.

[0058] It should be noted that the above-mentioned correction processing of the first inference signal information is to amplify the signal by using the gain coefficient required by the electronic pump speed control itself. This is because the control signal parameters obtained by the controller are relatively small, while the actual physical system control of the electronic pump speed requires larger signal parameters. Therefore, the signal is amplified to generate reasonable control parameters. This embodiment of the invention does not limit this process.

[0059] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0060] In an optional embodiment, the target control signal information is determined based on the basic analysis signal information and the control signal acquisition information, including: Based on the second analysis signal information and control signal acquisition information in the basic analysis signal information, the target control parameter information is determined; the target control parameter information includes the first control parameter, the second control parameter, and the third control parameter. Based on the target control parameter information, the first analysis signal information from the basic analysis signal information, and the control signal acquisition information, the target control signal information is determined.

[0061] It should be noted that the above-mentioned determination of the target control signal information based on the basic analysis signal information and control signal acquisition information is achieved by first using model parameter inference based on the multi-dimensional feedback signals of the system (current expected control displacement, actual control displacement of the previous control cycle, actual control signal of the previous cycle, etc.) to determine the control signal in real time by updating the model parameters. This method can realize fast and high-precision electronic pump speed control, which is beneficial to improving the control accuracy and control efficiency of the intelligent control system based on electronic pump. This embodiment of the invention does not limit the scope of the invention.

[0062] In this optional embodiment, as an optional control method, the target control parameter information is determined based on the second analysis signal information and the control signal acquisition information in the basic analysis signal information, including: Obtain weight parameter information; the weight parameter information includes a first weight value set, a second weight set, and a third weight set; the first weight set includes several first sub-weight values; the second weight set includes several second sub-weight values; the third weight set includes several third sub-weight values; The target control parameter information is obtained by using the second signal calculation model to calculate and process the weight parameter information, the second analysis signal information in the basic analysis signal information, and the control signal acquisition information. The calculation model for the second signal is as follows: ; In the formula, ; characterizing the first One control parameter; Characterizes the second analytical signal information in the basic analytical signal information; Characterizes the information acquired by the control signal; The table below, representing the first weight set, is numbered as follows: The first sub-weight value; The table below, representing the second weight set, is numbered as follows: The second sub-weight value; The table below, representing the first weight set, is numbered as follows: The first sub-weight value.

[0063] It should be noted that the third sub-weight value mentioned above is not limited to a value between [0,1] in this embodiment of the invention.

[0064] It should be noted that the first sub-weight value mentioned above is not limited to a value between [1, 10] in this embodiment of the invention.

[0065] It should be noted that the second sub-weight value mentioned above is not limited to a value between [1, 5] in this embodiment of the invention.

[0066] It should be noted that the above , , , 、 and The quantities used to characterize intermediate computational processes are not limited in this embodiment of the invention. Furthermore, The numerical value of the serial number is not limited in this embodiment of the invention. Furthermore, N is a positive integer between [3, 10], such as 3, 4, 5, 6, 7, 8, 9, 10, which is not limited in this embodiment of the invention.

[0067] It should be noted that the above-mentioned calculation and processing of the weight parameter information, the second analysis signal information in the basic analysis signal information, and the control signal acquisition information using the second signal calculation model to obtain the target control parameter information is achieved through the deep fusion of fuzzy logic control and multi-weighted calculation. This fusion mechanism endows the control system with dual characteristics, so as to significantly improve the adaptability and robustness of the control algorithm to strongly nonlinear and time-varying objects by utilizing the synergy of the two methods. This improves the ability to dynamically adjust the model parameters nonlinearly using multi-dimensional signals, so as to improve the ability of the first signal calculation model to generate control signals for nonlinear time-varying objects, thereby improving the control accuracy. This embodiment of the invention is not limited.

[0068] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.

[0069] In another optional embodiment, based on the target control parameter information, the first analysis signal information in the basic analysis signal information, and the control signal acquisition information, the target control signal information is determined, including: Acquire historical analysis signal information; the historical analysis signal includes first historical analysis signal and second historical analysis signal information; The target control signal information is determined by using the first signal calculation model to calculate and process the target control parameter information, the first analysis signal information in the basic analysis signal information, and the historical analysis signal information, so as to obtain the first control signal information. The calculation model for the first signal is as follows: A=s1·(X1-X2)+ s2·X1+ s3·(X1-2·X2+X3); In the formula, A represents the first control signal information; s1, s2 and s3 represent the first control parameter, the second control parameter and the third control parameter, respectively; X1, X2 and X3 represent the first analysis signal information, the first historical analysis signal and the second historical analysis signal information, respectively. The second control signal information is obtained by summing the first control signal information and the control signal acquisition information. The second control signal information is amplified to obtain the target control signal information.

[0070] It should be noted that the aforementioned first historical analysis signal and second historical analysis signal information respectively represent the first analysis signal information corresponding to the previous control cycle and the control cycle before that, and this embodiment of the invention does not limit this. Furthermore, when calculating the control signal using the first signal calculation model, utilizing the signal difference between the previous two control cycles (s3·(X1-2·X2+X3)) can reduce the accumulation of historical errors. Furthermore, in the first signal calculation model, the signal parameters of the current cycle (s2·X1) are also used separately. This is to maintain independent control of the current control expectation and system feedback parameters, avoiding the accumulation and saturation of control quantities due to long-term deviations. Simultaneously, to strengthen the correlation with the previous control cycle and enhance the robustness of the control process, the signal difference of the current cycle is also correlated with the previous control cycle (s1·(X1-X2)), thereby reducing control quantity fluctuations and improving control stability. This embodiment of the invention does not limit this.

[0071] Furthermore, the first control signal information calculated by the first signal calculation model represents the control signal variable situation that needs to be adjusted in the current control cycle. Therefore, the control signal of the current control cycle needs to be generated based on the actual control signal information of the previous control cycle (i.e., control signal acquisition information). Thus, it is necessary to sum the first control signal information and the control signal acquisition information. Furthermore, since the generated control signal needs to conform to the control parameters of the actual physical system, it is also necessary to amplify the second control signal information to obtain the real target control signal information. This embodiment of the invention does not limit this.

[0072] It is evident that implementing the intelligent variable frequency speed control method for electronic pumps described in the embodiments of the present invention is beneficial for overcoming the limitations of response speed and accuracy, improving the intelligent speed control accuracy of electronic pumps, and achieving a dual improvement in energy efficiency and stability.
