[0061] FIG5 is a schematic structural diagram of an embodiment of an excavator provided in an embodiment of the present application. DETAILED DESCRIPTION

[0062] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0063] Currently, the common method of calculating the excavator's load count and operating cycles by adding auxiliary components or configuring dedicated mining trucks is to further determine the excavator's operating status. This method requires additional components and is computationally intensive. Even when testing using simulated operating conditions, the significant difference between the simulated conditions and the real, variable, and complex operating conditions can lead to significant deviations in the simulated test results, resulting in low reliability. Furthermore, due to the influence of numerous factors such as operating conditions, working device configuration, and system operating characteristics, existing evaluation methods often focus on one aspect, limiting their credibility.

[0064] Based on this, an embodiment of the present application provides a method for determining the state of an excavator, the method comprising: obtaining the number of movements of a first working element in the excavator; the movement of the first working element is used to indicate the completion of loading; screening the number of movements of the first working element to determine a target number of movements; determining the current working condition of the excavator based on the relationship between the target number of movements and the preset number of movements; the working state of the excavator includes the current working condition. Thus, the number of movements of the original first working element in the excavator is used as the basis for calculating the number of vehicles loaded by the excavator, and only the number of movements of the first working element needs to be counted, which reduces the amount of calculation; at the same time, the number of movements of the first working element is screened to remove abnormal data, so as to improve the accuracy of the target number of movements determined by the number of movements of the first working element, thereby improving the accuracy of the current working condition of the excavator determined based on the target number of movements, and no additional components are required.

[0065] The method for determining the state of an excavator provided in the embodiment of the present application can be applied not only to excavators, but also to other mechanical equipment used for loading operations, especially earth stripping or mining material loading, without specific limitation here.

[0066] The following introduces a specific embodiment of a method for determining the state of an excavator in the present application. Figure 1 is a flow chart of a method for determining the state of an excavator provided by an embodiment of the present application. This specification provides method operation steps such as the embodiment or flow chart, but based on conventional or non-creative labor, more or fewer operation steps may be included. The order of steps listed in the embodiment is only one way of executing the order of many steps and does not represent the only execution order. When the actual system or server product is executed, it can be executed in sequence or in parallel according to the method shown in the embodiment or the accompanying drawings (for example, a parallel processor or a multi-threaded processing environment). Specifically, as shown in Figure 1, the method may include:

[0067] Step 110: Obtain the number of actions of the first working element in the excavator.

[0068] In the embodiment of the present application, the action of the first working element is used to indicate that loading is complete, and the number of actions of the first working element is also the number of times loading is completed. The first working element can be any element in the excavator that only takes action when loading is completed, and is not specifically limited here. For example, the first working element can be the whistle of the excavator. After completing a loading operation, the operator of the excavator, that is, the driver, will press the whistle to indicate that a loading operation is completed. Therefore, the whistle blowing action can be used as an action to indicate that loading is complete, that is, the whistle is used as the first working element. Therefore, without adding additional components to the excavator, the number of loadings of the excavator can be obtained by only counting the number of actions of the first working element, which reduces the amount of calculation.

[0069] Step 120: Screening the number of actions of the first working element to determine a target number of actions.

[0070] In the embodiment of the present application, in order to ensure the accuracy of the number of work counts of the first working element, the number of actions of the first working element is screened, and the actions that do not represent the completion of loading are removed to obtain the target number of actions, which is the number of loadings of the excavator.

[0071] Taking the whistle as the first working element as an example, the excavator driver will press the whistle not only when loading is completed, but also to remind others to avoid or issue a warning. At the same time, there are also cases where the whistle is accidentally triggered. At this time, it is necessary to remove these whistle actions that are not indicative of loading completion and only keep the whistle action that indicates loading is completed to ensure the accuracy of the target number of actions.

[0072] Step 130: Determine the current working condition of the excavator based on the relationship between the target number of actions and the preset number of actions.

[0073] In the embodiments of the present application, the working state of the excavator includes the current working condition. The working condition of the excavator is divided according to the number of loadings of the excavator, and is divided into multiple working condition levels based on the number of loadings. These working condition levels represent different working capabilities of the excavator. The preset number of loadings corresponds to the range of loadings of different working condition levels. The preset number of loadings can be divided according to the historical loading number of the excavator, that is, the historical target number of operations, or according to the management personnel's assessment requirements of the excavator's working capacity.

[0074] For example, the working conditions of an excavator can be divided into three working condition levels, including difficult working conditions, relatively hard working conditions, and loose working conditions. The number of loadings corresponding to difficult working conditions is less than the number of loadings corresponding to relatively hard working conditions, and the number of loadings corresponding to relatively hard working conditions is less than the number of loadings corresponding to loose working conditions. In other words, for the same excavator, difficult working conditions indicate that the working environment is not convenient for the excavator to carry out loading work, while loose working conditions indicate that the working environment is convenient for the excavator to carry out loading work. The above example is only one possible implementation method of the working condition division, and other division methods can also be used to divide the working conditions of the excavator. This application does not impose specific restrictions on this.

[0075] The method for determining the state of an excavator provided in an embodiment of the present application uses the number of actions of the original first working component in the excavator as the basis for calculating the number of loading vehicles of the excavator. It is only necessary to count the number of actions of the first working component, which reduces the amount of calculation; at the same time, the number of actions of the first working component is screened to eliminate abnormal data, so as to improve the accuracy of the target number of actions determined by the number of actions of the first working component, thereby improving the accuracy of the current working condition of the excavator determined based on the target number of actions, and no additional components are required.

[0076] In an optional embodiment, as described above, since there may be some action times of the first working element that do not represent the completion of loading, it is necessary to find and remove these action times that do not represent the completion of loading. Based on this, the action times of the first working element can be screened in the following ways: First, it can be screened according to the actual number of working cycles corresponding to each loading. Since for the same excavator, under the same operating environment, the actual number of working cycles corresponding to each loading should be consistent, the actual number of working cycles corresponding to loading can be used as the screening criterion; Second, it can be screened according to the time interval between two adjacent actions of the first working element. Since for the same excavator, under the same operating environment, the actual number of working cycles corresponding to each loading should be consistent, the time interval between two adjacent actions of the first working element should also be consistent. Therefore, the time interval between two adjacent actions of the first working element can be used as the screening criterion. It can also be determined based on the time interval between two adjacent actions of the first working element in combination with whether the excavator has completed a loading cycle.

[0077] In an optional embodiment, corresponding to the above-mentioned method of screening based on the actual number of working cycles corresponding to each loading, FIG2 is a flow chart of determining a target number of actions in a method for determining the state of an excavator provided in an embodiment of the present application. As shown in FIG2 , the above-mentioned step 120 of screening the number of actions of the first working element to determine the target number of actions may include the following steps:

[0078] Step 210: Obtain the number of times the second working element operates during each loading process.

[0079] In the embodiment of the present application, the second working element is used by the excavator when performing loading operations, and the operation count of the second working element is the number of operating actions of the second working element. The operating action of the second working element refers to the action performed by the second working element corresponding to the loading operation. In other words, if the second working element performs an action other than loading, even if the second working element has performed an action, this action will not be recorded in the operation count of the second working element.

[0080] In an optional embodiment, the excavator may include multiple second working elements. The actual number of working cycles may be determined by the number of operations of one of the second working elements, or by comprehensively considering the number of operations of multiple second working elements.

[0081] Taking an excavator as an example, its secondary working elements include the arm, boom, and slewing mechanism. For the arm, the loading operation consists of a single excavation motion lasting at least five seconds; for the boom, a single arm-raising motion lasting at least five seconds; and for the slewing mechanism, two rotations lasting at least five seconds, in opposite directions: one to the left and one to the right. When determining the actual number of working cycles of an excavator, one or more of the arm, boom, and slewing mechanism can be selected as the secondary working element, and the actual number of working cycles can be determined based on the number of times each element operates.

[0082] Step 220: Based on the number of operations of the second working element, determine the actual number of working cycles corresponding to the second working element in each loading process.

[0083] Specifically, step 220 may include the following steps:

[0084] Step a1: screening the operation times of the second operating element to determine the target operation times of the second operating element.

[0085] In step a1, in order to avoid recording the action that satisfies the loading operation judgment but does not actually represent the loading operation in the operation count of the second working element, for example, the second working element should only perform one loading operation in one loading process, but the driver performs the loading operation of the second working element twice in one loading process, then the operation count of the second working element will be recorded twice, but in fact only one should be recorded here. Therefore, the operation count of the second working element is screened to determine the target operation count of the second working element.

[0086] In an optional embodiment, the number of operations of the second working element can be filtered as follows: a first time interval between two adjacent actions of the second working element is obtained; if the first time interval is outside a preset time range, the number of the corresponding two adjacent actions of the second working element is excluded from the second working element operation count to determine the target number of operations. The preset time range is the time range corresponding to a preset working cycle, which can be determined based on the time of a single working cycle in the excavator's historical records and the time of a single working cycle obtained through theoretical calculations. Thus, the number of two adjacent actions of the second working element outside the time range corresponding to a single working cycle is excluded from the second working element operation count, improving the accuracy of the target number of operations. Alternatively, the recorded number of operations of the second working element can be filtered in chronological order. Since the preceding second working element action has already been filtered and confirmed to be a loading operation, when two adjacent actions with a first time interval outside the preset time range are found, only the subsequent second working element action is removed from the second working element operation count.

[0087] Step a2: The target number of operations of the second working element between two adjacent actions of the first working element is determined as the actual number of working cycles in each loading process.

[0088] In step a2, the actual number of working cycles is the number of working cycles during each loading process of the excavator during actual operation. The completion of a loading process is represented by the movement of the first working element. Therefore, the period between two consecutive movements of the first working element represents a complete loading process. The target number of operations of the second working element between two consecutive movements of the first working element is the actual number of working cycles during a loading process. Therefore, the number of operations of the second working element is filtered to eliminate abnormal data, thereby improving the accuracy of the actual number of working cycles.

[0089] In an optional embodiment, a mathematical statistical analysis can be performed on the actual number of working cycles during each loading process within a preset time period to obtain a target number of working cycles for the excavator within the preset time period. Methods such as mean, median, and mode can be used as mathematical statistical analysis methods to obtain a mathematically representative number of working cycles, so that the target number of working cycles obtained can fully represent the working cycle of the excavator during a loading process within the preset time period.

[0090] Step 230: Screening the number of actions of the first working element based on the actual number of working cycles to determine a target number of actions.

[0091] In an embodiment of the present application, the actual number of working cycles between the actions of two adjacent first working elements is compared with the target number of working cycles. If the actual number of working cycles is inconsistent with the target number of working cycles, the action is removed from the number of actions of the first working element, thereby obtaining the target number of actions. Optionally, considering that the number of working cycles in each loading process may fluctuate, the actual number of working cycles is considered to be consistent with the target number of working cycles when the actual number of working cycles is within the numerical range corresponding to the target number of working cycles, and conversely, the actual number of working cycles is considered to be inconsistent with the target number of working cycles when the actual number of working cycles is not within the numerical range corresponding to the target number of working cycles; wherein the numerical range can be a range that conforms to the distribution of the actual number of working cycles, obtained by performing mathematical statistical analysis on the actual number of working cycles that have been screened and obtained.

[0092] In an optional embodiment, the actual number of working cycles between two adjacent first working element movements can be compared with a preset number of working cycles. If the actual number of working cycles is inconsistent with the preset number of working cycles, the movement is removed from the number of first working element movements to obtain the target number of movements. Accordingly, if the actual number of working cycles is within the numerical range corresponding to the preset number of working cycles, the actual number of working cycles is considered consistent with the preset number of working cycles. Conversely, if the actual number of working cycles is not within the numerical range corresponding to the preset number of working cycles, the actual number of working cycles is considered inconsistent with the preset number of working cycles. The preset number of working cycles can be a theoretical number of working cycles for a single loading process, determined based on relevant loading parameters of the excavator.

[0093] By using the above method, the number of actions of the first working element is screened according to the actual number of working cycles in each loading process, thereby being able to screen the number of actions of the first working element according to the excavator's own working state, thereby improving the accuracy of the target number of actions.

[0094] In an optional embodiment, corresponding to the above-mentioned method of screening based on the time interval between two adjacent actions of the first working element, FIG3 is a flow chart of determining a target number of actions in a method for determining the state of an excavator provided in an embodiment of the present application. As shown in FIG3 , the above-mentioned step 120 of screening the number of actions of the first working element to determine the target number of actions may include the following steps:

[0095] Step 310: Obtain a second time interval between two adjacent whistle actions.

[0096] In the embodiment of the present application, the second time interval between two adjacent actions of the whistle should be consistent with the time corresponding to a loading process, so the number of actions of the first working element can be screened by obtaining the second time interval.

[0097] Step 320: If the second time interval is less than the preset time interval, the number of times of two adjacent actions corresponding to the whistle is excluded from the number of actions of the first working element to determine the target number of actions.

[0098] In the embodiment of the present application, the preset time interval is the time of a loading process corresponding to a preset number of working cycles. To prevent the whistle from being accidentally triggered or the whistle sounding action that does not indicate the completion of loading from being counted in the number of actions of the first working element, the second time interval is compared with the preset time interval. If the second time interval is less than the preset time interval, the number of the two adjacent whistle actions corresponding to the whistle is excluded from the number of actions of the first working element, thereby determining the target number of actions. Optionally, the recorded number of actions of the first working element can be filtered according to the chronological order. In this case, since the previous action of the first working element must have been filtered and confirmed to be the action of completing the loading, when two adjacent actions with a second time interval less than the preset time interval are found, only the subsequent action of the first working element is removed from the number of actions of the first working element.

[0099] In an optional embodiment, taking into account the certain range of fluctuations in the time interval between two adjacent whistle actions, a time range can be set based on the preset time interval. If the second time interval is within the time range, the action is retained; if the second time interval is not within the time range, the action is removed.

[0100] Through the above method, the number of actions of the first working element is screened according to the time interval between two adjacent actions of the first working element, so as to avoid mis-touch of the first working element or triggering of other functions from being counted in the target number of actions, thereby improving the accuracy of the target number of actions.

[0101] In an optional embodiment, the excavator's operating status includes not only the excavator's current operating condition but also its energy efficiency and bucket fill rate. The energy efficiency characterizes the amount of resources consumed by the excavator to complete a loading operation, while the bucket fill rate characterizes the loading efficiency of the excavator's bucket during the loading process. Accordingly, the method further includes the steps of determining the energy efficiency and bucket fill rate, specifically as follows: obtaining the excavator's resource consumption and a preset number of working cycles; determining the energy efficiency based on the ratio of the resource consumption to a target number of motions; and determining the bucket fill rate based on the ratio of the preset number of working cycles to a target number of working cycles. Thus, the excavator's energy efficiency and bucket fill rate are determined based on the determined target number of motions and target number of working cycles, as well as the obtained resource consumption and preset number of working cycles, thereby determining the excavator's operating status from multiple perspectives.

[0102] In an optional embodiment, the method can further analyze the working state of the excavator to determine the excavator's applicable working environment, adapted working components, etc., that is, further guide the excavator's component configuration and work arrangement based on the analysis results. For example, it can guide excavator users to improve their awareness and arrange excavators with different configurations according to different working conditions to achieve optimal production efficiency; it can provide direct data support for new R&D concepts to developers to develop more competitive excavator products; and it can enable the selection of the most reasonable excavator machine and configuration based on data support. Specifically, it can be divided into the following situations:

[0103] In the first case, the operating status of the excavator and the working status of the working components are analyzed based on the changes in the working status of the same excavator before and after. Specifically, the current working status and historical working status of the first excavator are obtained; the current working status is compared and analyzed with the historical working status to determine the working status of the working components of the first excavator. The historical working status refers to the working status of the first excavator during a period of past working time, such as the working status of the past few days or months; the current working status refers to the working status of the first excavator during the current period of working time. By comparing and analyzing the current working status with the historical working status, the working status of the working components in the first excavator can be obtained compared with the past period of working time. For example, if the target number of working cycles in the current working status is larger than the target number of working cycles in the historical working status, it means that the working efficiency of the second working component used for loading operations in the first excavator has decreased, and it is necessary to further determine whether the relevant working components are damaged, etc.

[0104] In the second scenario, based on a comparison of the working states of two excavators under the same working environment or working conditions, an analysis is performed to determine which working environment or working conditions are more suitable for different excavators. Specifically, a first working state of the first excavator and a second working state of the second excavator are obtained; the first working state and the second working state are compared and analyzed to determine the comparative analysis results of the first excavator and the second excavator. This scenario is further illustrated below with reference to Table 1. As shown in Table 1, as the number of loading vehicles decreases, the energy efficiency of the first excavator increases significantly, indicating that the first excavator is more suitable for working in loose conditions than in difficult conditions. This also shows that different working conditions, that is, different working environments, have a significant impact on the loading efficiency and resource consumption of an excavator. When selecting an excavator, it is necessary to make the choice based on the specific working environment and working conditions. Furthermore, a comparison of the first excavator and the second excavator shows that the loading efficiency of the first excavator and the second excavator is comparable, but in loose conditions, that is, when the number of loading vehicles is between 300 and 350, the energy efficiency of the second excavator is lower than that of the first excavator, indicating that the second excavator consumes less resources.

[0105] Table 1

[0106] In the third case, based on the comparison of the working states of the same excavator before and after the replacement of the components, the working components that are more suitable for the excavator are analyzed and determined. For example, an excavator can be equipped with buckets of different sizes. Whether it is reasonable for the user is a difficult decision. The above problem will be simplified by choosing the technical solutions in the embodiments of this application. Different machines or configurations can be selected under different working conditions. If the working condition is single, a specific size of bucket can be selected. On the contrary, if it is a comprehensive working condition, a specific machine or configuration recommendation will be given based on the data. Specifically, the third working state of the target working component of the first excavator before replacement and the fourth working state after replacement are obtained; the third working state and the fourth working state are compared and analyzed to determine the comparative analysis results before and after the replacement of the target working component. This situation is further illustrated below with reference to Table 2. As shown in Table 2, for this excavator, under loose working conditions (i.e., when loading more vehicles), a 7.2-cubic-meter bucket has lower energy efficiency, higher work efficiency, and lower resource consumption. Under harder working conditions, the energy efficiency and fill rate of the 7.2-cubic-meter bucket and the 6.5-cubic-meter bucket are similar. Under difficult working conditions, the 7.2-cubic-meter bucket has higher energy efficiency, while the 6.5-cubic-meter bucket has lower energy efficiency, higher work efficiency, and lower resource consumption. This comparison allows you to select a more appropriate bucket capacity for the specific working environment and working conditions, thereby improving resource utilization and work efficiency.
