Based on the multi-dimensional operating parameters, the target energy conversion parameters of the hydraulic system are calculated, including:

[0102] Based on the first hydraulic temperature parameter and the ambient temperature parameter, the first temperature difference parameter of the hydraulic system is calculated. The first temperature difference parameter is used to represent the heat dissipation temperature difference of the hydraulic system.

[0103] Based on the second hydraulic temperature parameter, the second temperature difference parameter of the hydraulic system is calculated. The second temperature difference parameter is used to represent the temperature change of the hydraulic system within a preset time period.

[0104] The target energy conversion parameters of the hydraulic system are calculated based on the first temperature difference parameter, the second temperature difference parameter, and the power consumption parameter.

[0105] In this embodiment of the invention, optionally, the first temperature difference parameter is equal to the first hydraulic temperature parameter minus the ambient temperature parameter. On this basis, optionally, the above formula can be weighted and biased by combining parameters such as the service life of the hydraulic system and the test time.

[0106] In this embodiment of the invention, optionally, the second temperature difference parameter is the difference between the second hydraulic temperature parameters under a preset time period;

[0107] In this embodiment of the invention, optionally, the power consumption parameters mentioned above include at least one power consumption item selected from power parameters, fuel consumption parameters, speed parameters, and displacement parameters;

[0108] It is evident that implementing this optional embodiment can, based on the calculated and analyzed heat dissipation temperature difference of the hydraulic system and the temperature change over a preset period, combined with the power consumption parameters of the hydraulic system, deeply analyze the underlying logic of temperature changes in the hydraulic system from the perspective of the internal kinetic energy conversion of the hydraulic system, such as oil temperature changes, thereby improving the accuracy and comprehensiveness of the calculation and analysis of the target energy conversion parameters of the hydraulic system, and improving the depth, accuracy, and comprehensiveness of the early warning analysis of temperature anomalies in the hydraulic system.

[0109] In this optional embodiment, as an optional implementation, the above-mentioned calculation of the target energy conversion parameters of the hydraulic system based on the first temperature difference parameter, the second temperature difference parameter, and the power consumption parameter includes:

[0110] Based on the first temperature difference parameter and the second temperature difference parameter, the application scenario parameters of the hydraulic system are determined. The application scenario parameters are used to represent the application scenario of the hydraulic system.

[0111] Based on the application scenario parameters, the first priority value of the first temperature difference parameter and the second priority value of the second temperature difference parameter are matched, and the target power consumption item in the power consumption parameters of the hydraulic system within the preset time period is determined, as well as the third priority value of the target power consumption item is matched. The power consumption parameters include at least one power consumption item among power parameters, fuel consumption parameters, speed parameters, and displacement parameters. The target power consumption item is matched with the application scenario parameters.

[0112] The target energy conversion parameters of the hydraulic system are calculated based on the first temperature difference parameter and its first priority weight, the second temperature difference parameter and its second priority weight, the target power consumption term and its third priority weight.

[0116] Wherein, △Td is used to represent the target energy conversion parameter mentioned above, △Ty is used to represent the second temperature difference parameter mentioned above, W is used to represent the power parameter, fuel consumption parameter, or displacement parameter mentioned above, n is used to represent the speed parameter mentioned above, and △Ts is used to represent the first temperature difference parameter mentioned above.

[0117] As can be seen, implementing this optional embodiment can further analyze and determine the application scenario parameters of the hydraulic system based on the first temperature difference parameter and the second temperature difference parameter. Then, combined with the application scenario of the hydraulic system, it matches the first priority value of the first temperature difference parameter representing the heat dissipation temperature difference of the hydraulic system and the second priority value of the second temperature difference parameter representing the temperature change of the hydraulic system within a preset time period. It also matches and determines the target power consumption item and its third priority value in the power consumption parameters of the hydraulic system within the preset time period. Thus, based on the first temperature difference parameter and its first priority value, the second temperature difference parameter and its second priority value, and the target power consumption item and its third priority value, the target energy conversion parameters of the hydraulic system are calculated. This can further analyze the underlying logic of temperature changes in the hydraulic system from the perspective of the inherent kinetic energy conversion of the hydraulic system operation and the actual application scenario of the hydraulic system, thereby improving the accuracy and comprehensiveness of the calculation and analysis of the target energy conversion parameters of the hydraulic system, and improving the depth, accuracy, and comprehensiveness of the temperature anomaly early warning analysis of the hydraulic system.

[0124] Obtain the third temperature difference parameter, the fourth temperature difference parameter, and the historical power consumption parameter corresponding to the energy conversion parameters in the previous adjacent frame. The third temperature difference parameter corresponds to the first temperature difference parameter, the fourth temperature difference parameter corresponds to the second temperature difference parameter, and the historical power consumption parameter corresponds to the power consumption parameter.

[0125] Based on the first temperature difference parameter, the second temperature difference parameter, and the power consumption parameter, the fourth priority value of the target energy conversion parameter is matched;

[0126] Based on the third temperature difference parameter, the fourth temperature difference parameter, and the historical power consumption parameter, the fifth priority value of the energy conversion parameter in the previous adjacent frame is matched;

[0127] Update the energy conversion parameters in the previous adjacent frames based on the target energy conversion parameters and their fourth priority value, the energy conversion parameters in the previous adjacent frames and their fifth priority value.

[0128] In this embodiment of the invention, optionally, the aforementioned preceding adjacent frame is used to represent the moment when the previous acquisition of the target energy conversion parameters was triggered in step 105 of embodiment 101 of the invention.

[0129] It is evident that implementing the embodiments of the present invention can further improve the accuracy of the calculation of the first target distance value by updating the historical energy conversion parameters, thereby preventing the historical parameters from affecting the accuracy of the temperature anomaly early warning analysis of the hydraulic system in this application, and further improving the timeliness of the temperature anomaly early warning analysis of the hydraulic system.

[0130] 104. Based on the first target distance value, determine whether the hydraulic system meets the preset temperature anomaly warning conditions;

[0131] In another optional implementation of this invention, the above-mentioned determination of whether the hydraulic system meets the preset temperature anomaly warning condition based on the first target distance value includes:

[0132] For each distance threshold range in the preset multi-dimensional distance threshold range, calculate the second target distance value between the distance threshold range and the first target distance value. The second target distance value is used to represent the degree of distance between the first target distance value and the distance threshold range.

[0133] Based on all the second target distance values, within the preset multi-dimensional distance threshold range, match the target distance threshold range of the first target distance value;

[0134] Determine whether the first target distance value is within the target distance threshold range. If it is determined that the first target distance value is within the target distance threshold range, then the hydraulic system is determined to meet the preset temperature abnormality warning conditions.

[0135] As can be seen, implementing this optional embodiment can calculate the second target distance value between each distance threshold range in the preset multi-dimensional distance threshold range and the first target distance value, and then match the target distance threshold range of the first target distance value in the preset multi-dimensional distance threshold range. This makes the judgment logic for determining whether the hydraulic system meets the preset temperature anomaly warning conditions more flexible and accurate, thereby improving the flexibility and accuracy of the temperature anomaly warning analysis of the hydraulic system and helping to reduce the false judgment rate of temperature anomaly warning of the hydraulic system.

[0136] 105. When it is determined that the hydraulic system meets the preset temperature anomaly warning conditions, the temperature anomaly warning parameters of the hydraulic system are generated according to the first target distance value and the preset temperature anomaly warning conditions. The temperature anomaly warning parameters are used to perform temperature anomaly warning operations on the hydraulic system that match the temperature anomaly warning parameters.

[0137] In this embodiment of the invention, optionally, the above-mentioned temperature anomaly warning operation includes, but is not limited to, one or more methods such as display, sound and light combination, and sending information, and the specific content and form vary depending on the different parameters described below.

[0138] As can be seen, implementing the embodiments of the present invention can calculate the target energy conversion parameter representing the power consumption and energy conversion of the hydraulic system based on the acquired multi-dimensional operating parameters of the hydraulic system. This allows for in-depth analysis of the underlying logic of temperature changes in the hydraulic system, such as oil temperature changes, from the perspective of the inherent kinetic energy conversion during hydraulic system operation. This improves the depth, accuracy, and comprehensiveness of temperature anomaly early warning analysis of the hydraulic system. By combining the acquired historical energy conversion parameters of the hydraulic system, a first target distance value is calculated between the target energy conversion parameter and the acquired historical energy conversion parameters to reflect the energy conversion changes of the hydraulic system. This facilitates the extraction of features from historical energy conversion parameters and, combined with statistical characteristics, improves the accuracy and comprehensiveness of the analysis. This method improves the depth, accuracy, and comprehensiveness of temperature anomaly early warning analysis in hydraulic systems, while also enhancing the efficiency and immediacy of such analysis. Based on a first target distance value, it determines whether the hydraulic system meets preset temperature anomaly early warning conditions. If the determination is yes, it generates temperature anomaly early warning parameters for the hydraulic system using the first target distance value and the preset temperature anomaly early warning conditions. This allows for the execution of temperature anomaly early warning operations that match these parameters. This approach enhances the stability and safety of temperature anomaly early warning analysis in hydraulic systems, further improving its accuracy and ensuring operational safety and stability, ultimately safeguarding the user's production safety.

[0139] In an optional embodiment, the target distance threshold range includes at least two distance threshold sub-ranges, and the method further includes:

[0140] When it is determined that the first target distance value is within the target distance threshold range, the target distance threshold sub-range is matched among all distance threshold sub-ranges based on the first target distance value, and the first target distance value is within the target distance threshold sub-range.

[0141] Determine whether the reference feature value corresponding to the first target distance value is less than or equal to the preset feature threshold corresponding to the reference feature value. When it is determined that the reference feature value corresponding to the first target distance value is less than or equal to the preset feature threshold corresponding to the reference feature value, generate feature representation parameters of the reference feature value based on the reference feature value and the preset feature threshold. The reference feature value includes at least one of the first temperature difference parameter, the second temperature difference parameter, and the power consumption parameter. The feature representation parameters are used to represent the meaning of the feature change of the reference feature value.

[0142] Optionally, based on the first target distance value and preset temperature anomaly warning conditions, temperature anomaly warning parameters for the hydraulic system are generated, including:

[0143] When it is determined that the reference feature value corresponding to the first target distance value is less than or equal to the preset feature threshold corresponding to the reference feature value, the temperature anomaly warning parameters of the hydraulic system are generated based on the first target distance value, the target distance threshold range and the feature characterization parameters.

[0144] When it is determined that the reference feature value corresponding to the first target distance value is greater than the preset feature threshold corresponding to the reference feature value, the temperature anomaly warning parameters of the hydraulic system are generated based on the first target distance value and the target distance threshold range.

[0145] It is evident that implementing this optional embodiment can further improve the accuracy and comprehensiveness of generating temperature anomaly warning parameters for the hydraulic system by further analyzing the first target distance value within the target distance threshold range and then combining it with the characteristic changes of the reference feature value, thereby improving the accuracy and comprehensiveness of temperature anomaly warning for the hydraulic system.

[0147] Calculate the rate of change parameter value of the first target distance;

[0148] Determine whether the change rate parameter value is greater than or equal to the preset change rate parameter threshold of the first target distance value. If it is determined that the change rate parameter value is greater than or equal to the preset change rate parameter threshold of the first target distance value, then update the temperature anomaly warning parameter according to the change rate parameter value.

[0149] It is evident that implementing this optional embodiment can further reflect whether the temperature rise of the hydraulic system is accurately controlled by calculating the rate of change parameter value of the first target distance value. In the case of inaccurate control, the temperature anomaly warning parameter is updated based on the rate of change parameter value, thereby further improving the accuracy and timeliness of the temperature anomaly warning of the hydraulic system. Through reverse monitoring, it is possible to further improve the operational stability of the hydraulic system and the effectiveness of the temperature anomaly warning.
