The following are detailed descriptions.

[0086] Embodiment 1

[0087] See also Figure 1 , Figure 1 : is a flow chart of a hydraulic system fault warning method based on multi-dimensional parameter fusion analysis disclosed in an embodiment of the present invention. Figure 1 The hydraulic system fault warning method based on multi-dimensional parameter fusion analysis described can be applied to hydraulic systems, excavators and other host product equipment using plunger pumps, plunger motors, and hydraulic cylinders, and can also be applied to the associated intelligent devices of the above-mentioned devices, which include but are not limited to one or more of battery devices, cloud devices, edge computing devices, relay devices, base station devices, urban management devices, and intelligent network devices, which are not limited in the embodiments of the present invention. Figure 1 As shown, the hydraulic system fault warning method based on multi-dimensional parameter fusion analysis may include the following operations:

[0088] 101. Collecting first multi-dimensional state parameters within a preset range of the hydraulic system, where the first multi-dimensional state parameters include second multi-dimensional state parameters of a target object in the hydraulic system and third multi-dimensional state parameters of the hydraulic system itself;

[0089] In the embodiment of the present invention, optionally, the above-mentioned target object includes but is not limited to one or more of solid particles, liquid metal, impurities, etc.;

[0090] 102. Determine, based on the first multidimensional state parameter, whether there is at least one first region in the hydraulic system, a fourth multidimensional state parameter of the first region matches a preset multidimensional state parameter, and the fourth multidimensional state parameter is generated based on the first multidimensional state parameter;

[0091] In an embodiment of the present invention, as an optional implementation, the second multi-dimensional state parameter includes a first state sub-parameter and a second state sub-parameter, wherein the first state sub-parameter includes at least one of a shape parameter, a size parameter, an adhesion parameter, a material type parameter, a softness and hardness parameter, a weight parameter, and an attachment surface parameter, and the second state sub-parameter includes at least one of a position parameter and a color parameter;

[0092] And, optionally, judging whether there is at least one first area in the hydraulic system according to the first multi-dimensional state parameter includes:

[0093] For each target object, a comprehensive performance parameter of the target object is calculated according to the first state sub-parameter of the target object, where the comprehensive performance parameter is used to represent the comprehensive performance of the target object in the hydraulic system;

[0094] Calculate the impact value parameter of the target object on the hydraulic system according to the comprehensive performance parameter and the preset comprehensive performance threshold parameter, where the impact value parameter is used to indicate the degree of impact of the target object on the hydraulic system;

[0095] Determine whether the influence value parameter is greater than or equal to a preset influence threshold parameter, and when it is determined that the influence value parameter is greater than or equal to the preset influence threshold parameter, determine the second area corresponding to the target object according to the second state sub-parameter of the target object;

[0096] It is determined whether there is at least one first region in the hydraulic system according to all the second regions and the third multi-dimensional state parameter.

[0097] In the embodiment of the present invention, it should be noted that when there is no target object in the hydraulic system, the second multi-dimensional state parameter may be empty. At this time, optionally, the determination of whether there is at least one first area in the hydraulic system according to the first multi-dimensional state parameter may directly trigger the determination of whether there is at least one first area in the hydraulic system according to the third multi-dimensional state parameter;

[0098] In the embodiment of the present invention, for example, when the above-mentioned target object is solid particles, the target objects with different first state sub-parameters have different degrees of influence on the hydraulic system. For example, an increase in the number of solid particles in the 5-15 micron group can easily cause the hydraulic valve to get stuck, indicating that the risk of valve sticking is increased, and the reason may be filter failure. At this time, an alarm should be sounded to prompt the staff to check the filter; solid particles in the 15-50 micron group are in a normal wear state, and their number indicates the degree of wear. Normally, the number should remain stable. If the number suddenly increases, it means that the wear has intensified. At this time, an alarm should be sounded to prompt the staff that the hydraulic system has abnormal wear; solid particles larger than 50 microns indicate that the wear is very serious, a minor fault has occurred or a major fault is about to occur. At this time, an alarm should be sounded to prompt the staff to stop the machine for inspection. Based on this, when the target object has other first state sub-parameters, the corresponding performance is also different, and the embodiment of the present invention does not make specific limitations on this.

[0099] It can be seen that the implementation of this optional embodiment can calculate, for each target object, the comprehensive performance parameter of the target object used to represent the comprehensive performance of the target object in the hydraulic system based on the collected multi-dimensional optional first state sub-parameters of the target object, and then calculate the influence value parameter of the target object used to represent the degree of influence of the target object on the hydraulic system in combination with the preset comprehensive performance threshold parameter, and when the influence value parameter is greater than or equal to the preset influence threshold parameter, the second area corresponding to the target object is determined according to the second state sub-parameter of the target object, and it is judged whether there is at least one first area in the hydraulic system according to all the second areas and the third multi-dimensional state parameters, which can help improve the analysis accuracy, comprehensiveness and timeliness of fault warning brought by the target object to the hydraulic system, and help improve the accuracy, comprehensiveness and timeliness of fault warning of the hydraulic system.

[0100] In this optional embodiment, as an optional implementation, the third multi-dimensional state parameter is used to represent the state of at least one third area in the hydraulic system, and the third multi-dimensional state parameter includes at least one third state sub-parameter of pressure parameter, flow parameter, vibration parameter, sound field parameter, and transmittance parameter; the above-mentioned judging whether there is at least one first area in the hydraulic system based on all the second areas and the third multi-dimensional state parameter includes:

[0101] For each third region, determining a preset priority parameter of the third region; matching a dimension state threshold parameter of each third state sub-parameter under the third region according to the preset priority parameter;

[0102] For each third-state sub-parameter, determine whether the third-state sub-parameter is greater than or equal to the dimension state threshold parameter corresponding to the third-state sub-parameter. When it is determined that the third-state sub-parameter is greater than or equal to the dimension state threshold parameter corresponding to the third-state sub-parameter, calculate the target distance value between the third-state sub-parameter and the dimension state threshold parameter corresponding to the third-state sub-parameter. The target distance value is used to represent the distance between the third-state sub-parameter and the corresponding dimension state threshold parameter.

[0103] According to all the target distance values, predict at least one fourth area in the hydraulic system, the fourth area is a preparatory abnormality warning area in the hydraulic system, and the fourth area is different from the second area;

[0104] At least one first region present in the hydraulic system is determined based on all the second regions and all the fourth regions.

[0105] In the embodiment of the present invention, optionally, the third region is a region for characterizing the multi-dimensional state of the hydraulic system itself, and does not limit the existence of anomalies, but further predicts the fourth region on this basis, and then determines the first region;

[0106] Further optionally, the above-mentioned preset priority parameter may essentially represent the usage frequency, importance, function, etc. of the component corresponding to the third area, or the preset priority parameter may essentially be proportional to the usage frequency, importance, function, etc. of the above-mentioned component;

[0107] Further optionally, the determination of the third area and the determination of the third state sub-parameters under the third area may not require repeated collection to save computing power. The solution is to determine which third state sub-parameters need to be collected through the above-mentioned preset priority parameters of the components under each third area. For example, for the pump outlet and actuator inlet position, the third state sub-parameters may include pressure parameters; in the hydraulic pipeline, the third state sub-parameters may include flow parameters to measure the hydraulic oil flow; on the shell or nearby structures, the third state sub-parameters may include vibration parameters; near the hydraulic oil tank, pipeline or key components, the third state sub-parameters may include sound field parameters, temperature parameters, etc. The above are not specifically limited and are subject to the needs of the actual application scenario.

[0108] It can be seen that the implementation of this optional embodiment can match the dimensional state threshold parameter of each third state sub-parameter under each third area based on the preset priority parameter of each third area determined, and then for each third state sub-parameter, respectively determine whether the third state sub-parameter is greater than or equal to the dimensional state threshold parameter corresponding to the third state sub-parameter, and when the judgment result is yes, calculate the target distance value between the third state sub-parameter and the dimensional state threshold parameter corresponding to the third state sub-parameter for representing the distance between the third state sub-parameter and the corresponding dimensional state threshold parameter, and predict at least one fourth area in the hydraulic system as a preparatory abnormal warning area in the hydraulic system based on all the second areas and all the fourth areas, and then determine at least one first area in the hydraulic system based on all the second areas and all the fourth areas, so as to further improve the determination accuracy of the first area from the level of the hydraulic system itself, and improve the comprehensiveness, accuracy and timeliness of the hydraulic system fault warning.

[0109] In this optional embodiment, as another optional implementation, when there are at least two third state sub-parameters, the above-mentioned prediction of at least one fourth area in the hydraulic system based on all target distance values ​​includes:

[0110] Determine at least two arbitrary target distance values ​​as a target distance value set;

[0111] For each target distance value in each target distance value set, calculating a correlation value between the third state sub-parameter corresponding to the target distance value and the third state sub-parameters corresponding to other target distance values ​​in the target distance value set, the correlation value being used to indicate a correlation influence degree between the third state sub-parameters in the target distance value set;

[0112] At least one fourth region existing in the hydraulic system is predicted according to all the correlation degree values.

[0113] In the embodiment of the present invention, optionally, the above-mentioned target distance value sets may include multiple ones, but there should be at least one target distance value set for each target distance value.

[0114] It can be seen that the implementation of this optional embodiment determines any at least two target distance values ​​as a target distance value set; for each target distance value in each target distance value set, a correlation value is calculated between the third state sub-parameter corresponding to the target distance value and the third state sub-parameters corresponding to other target distance values ​​in the target distance value set, which is used to represent the degree of correlation influence between the third state sub-parameters in the target distance value set, and then based on all the correlation values, at least one fourth area existing in the hydraulic system is predicted, which can further combine the degree of correlation influence between each third state sub-parameter to further improve the prediction accuracy and scientificity of the fourth area.

[0115] In this optional embodiment, as another optional implementation manner, the above-mentioned determining at least one first area existing in the hydraulic system according to all the second areas and all the fourth areas includes:

[0116] For each second region, according to the first state sub-parameter, the second state sub-parameter and the influence value parameter of the target object corresponding to the second region, an abnormal type parameter of the second region is analyzed, the abnormal type parameter is used to indicate the type of influence of the second region on the hydraulic system, and the influence type is used to indicate that the second region has at least one of wear influence, jam influence and burning influence on the hydraulic system;

[0117] Matching the first area priority value of each second area according to the abnormal type parameters of all second areas;

[0118] For each fourth area, calculating the overlap value between the fourth area and each third area; matching the second area priority value of the fourth area according to all the overlap values ​​and the preset priority parameter of each third area;

[0119] At least one first zone existing in the hydraulic system is determined according to all the first zone priority values ​​and all the second zone priority values.

[0120] It can be seen that the implementation of this optional embodiment can further, on the one hand, after the fourth area in the hydraulic system including the potential abnormal point is predicted and the second area corresponding to the target object, it can further combine the first state sub-parameter, the second state sub-parameter and the influence value parameter of each second area corresponding to the target object, analyze the abnormal type parameter of the second area used to represent the multi-dimensional optional influence type of the second area on the hydraulic system, and match the first area priority value of each second area according to the abnormal type parameters of all second areas; on the other hand, for each fourth area, calculate the overlap value between the fourth area and each third area; match the second area priority value of the fourth area according to all overlap values ​​and the preset priority parameters of each third area, and finally, determine at least one first area in the hydraulic system according to all first area priority values ​​and all second area priority values, so as to further improve the accuracy and comprehensiveness of determining the first area, which is conducive to further improving the accuracy and comprehensiveness of fault prediction of the hydraulic system.

[0121] In an optional embodiment, the above-mentioned determining at least one first area in the hydraulic system according to all the first area priority values ​​and all the second area priority values ​​includes:

[0122] Determine whether there is an intersection area between all the second areas and all the fourth areas. When it is determined that there is an intersection area between all the second areas and all the fourth areas, calculate a third area priority value of the intersection area according to the first area priority value of the second area corresponding to the intersection area and the second area priority value of the fourth area, and the third area priority value is greater than the first area priority value and the second area priority value;

[0123] For each of all first area priority values, all second area priority values ​​and all third area priority values, according to the preset priority threshold, at least one first area existing in the hydraulic system is determined among all second areas, all fourth areas and all intersection areas, and the priority value corresponding to the first area is greater than or equal to the preset priority threshold.

[0124] In this optional embodiment, in the process of determining at least one first area existing in the hydraulic system among all the second areas, all the fourth areas and all the intersection areas according to the preset priority threshold, the first area may include part of the second area, part of the fourth area and part of the intersection area, which is related to the actual application scenario and is not specifically limited in this embodiment of the present invention.

[0125] It can be seen that the implementation of this optional embodiment can further determine whether there is an intersection area between all the second areas and all the fourth areas, thereby calculating the third area priority value of the intersection area according to the first area priority value of the second area corresponding to the intersection area and the second area priority value of the fourth area. For each priority value among all the first area priority values, all the second area priority values ​​and all the third area priority values, according to the preset priority threshold, at least one first area existing in the hydraulic system is determined in all the second areas, all the fourth areas and all the intersection areas, which is conducive to reducing excessive redundancy of the first area, improving the accuracy and comprehensiveness of fault warning of the first area, and helping to further improve the accuracy and comprehensiveness of fault warning of the hydraulic system.

[0126] 103. When the judgment result is yes, a fault warning parameter of the hydraulic system is generated according to the fourth multi-dimensional state parameters of all the first areas, and the fault warning parameter is used to indicate the health status of the first area and the hydraulic system.

[0127] It can be seen that the implementation of the embodiment of the present invention can determine whether there is at least one first area in the hydraulic system whose fourth multidimensional state parameters match the preset multidimensional state parameters through the collected second multidimensional state parameters of the target object existing in the hydraulic system included in the preset range of the hydraulic system and the first multidimensional state parameters of the third multidimensional state parameters of the hydraulic system itself. If so, a fault warning parameter of the hydraulic system for indicating the health status of the first area and the hydraulic system is generated based on the fourth multidimensional state parameters of all the first areas. This can improve the accuracy of detection and warning of the cleanliness of the hydraulic system from the perspective of the detection of multidimensional state parameters at the two levels of the target object and the hydraulic system, while improving the accuracy, timeliness and a priori nature of the fault warning of the hydraulic system, which is conducive to timely warning of fault anomalies and potential anomalies, and improving the application safety and stability of the hydraulic system.
