[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] To address the problems of high labor costs, low efficiency, and poor accuracy associated with manually recording the number of buckets on excavators in existing technologies, this invention provides a method for identifying the number of buckets on an excavator, applied to a cloud server. Figure 1 This is one of the flowcharts illustrating the excavator bucket count recognition method provided in this embodiment of the invention, such as... Figure 1 As shown, the excavator bucket count identification method includes the following steps:

[0053] Step 110: Acquire the electrical signals of the target excavator in real time.

[0054] Specifically, when the operator operates the handle of the target excavator, the corresponding electrical signals of the target excavator will change. During the operation, the target excavator can send these electrical signals to a cloud server, which can then acquire them in real time. When the target excavator is a front shovel excavator, the electrical signals may include a bucket opening signal. When the target excavator is a backhoe excavator, the electrical signals may include digging signals, swing signals, and unloading signals.

[0055] Step 120: Determine the current action of the target excavator based on the action electrical signal. If the current action is the target action, record the number of consecutive executions of the target action at the current time.

[0056] Specifically, the cloud server can determine the current action of the target excavator based on the currently acquired electrical signals. If the current action is the target action, it can record the number of consecutive executions of the target action at the current moment. The type of the target action can be determined based on the type of the target excavator, and this embodiment of the invention does not impose specific limitations here. For example, if the target excavator is a front shovel excavator, the target action can be a bucket opening action; if the target excavator is a backhoe excavator, the target action can be a slewing action or an unloading action.

[0057] In one embodiment, determining the current action of the target excavator based on the motion electrical signal, and recording the number of consecutive executions of the target action at the current moment if the current action is the target action, includes:

[0058] Identify the action electrical signal and determine whether the action corresponding to the action electrical signal is an action in the first action set;

[0059] If the action corresponding to the action signal is an action in the first action set and the value of the action signal is greater than the corresponding threshold in the preset threshold set, then the current action of the target excavator is determined to be the target action.

[0060] If the current action is the target action, record the number of consecutive executions of the target action at the current time.

[0061] Specifically, the action electrical signal of the target excavator can carry action attribute tags. Different action types have different action attribute tags. The cloud server can identify the action corresponding to the action electrical signal based on the action attribute tags and determine whether the action corresponding to the action electrical signal is an action in the first action set. The type of action in the first action set can be determined based on the type of the target excavator, and this embodiment of the invention does not impose specific limitations here. Since the handle of the target excavator usually has a certain dead zone, that is, the handle movement is within a certain small range. Although the value of the generated action electrical signal is not zero, it is difficult to consider the action corresponding to the action electrical signal as a valid action. Therefore, it is necessary to set a preset threshold and compare it with the value of the action electrical signal. If the value of the action electrical signal (e.g., current value or voltage value) is greater than the preset threshold, the action corresponding to the action electrical signal can be considered a valid action. If the value of the action electrical signal is less than or equal to the preset threshold, the action corresponding to the action electrical signal can be considered an invalid action. Furthermore, if the action corresponding to the action electrical signal is an action in the first action set and the value of the action electrical signal is greater than the threshold corresponding to the action in the preset threshold set, the current action of the target excavator can be determined as the target action. The preset threshold set can be set according to the type of action in the first action set. The thresholds in the preset threshold set corresponding to different actions in the first action set can be the same or different. This embodiment of the invention does not make specific limitations here. It can be understood that setting different thresholds for different actions in the first action set can further improve the accuracy of the Dou Shu recognition. The value of the action electrical signal can be a current value or a voltage value. When the value of the action electrical signal is a current value, the threshold in the preset threshold set can be a preset current threshold, for example, the preset current threshold can be 400 mA. When the value of the action electrical signal is a voltage value, the threshold in the preset threshold set can be a preset voltage threshold. Furthermore, when the current action is the target action, the number of consecutive executions of the target action at the current moment can be recorded.

[0062] In the above embodiments, when the action corresponding to the action signal is an action in the first action set and the value of the action signal is greater than the corresponding threshold in the preset threshold set, the current action of the target excavator is determined as the target action. This eliminates the influence of abnormal operation and makes the recorded number of consecutive executions of the target action at the current moment more accurate, laying the foundation for subsequently determining the current number of buckets of the target excavator.

[0063] In one embodiment, the first action set includes the action of opening the bucket, and the preset threshold set includes a first threshold;

[0064] The step of determining the current action of the target excavator as the target action when the action corresponding to the action electrical signal is an action in the first action set and the value of the action electrical signal is greater than the corresponding threshold in the preset threshold set includes:

[0065] If the action corresponding to the action signal is a bucket opening action and the value of the action signal is greater than the first threshold, the current action of the target excavator is determined to be the target action.

[0066] Specifically, when the target excavator is a front shovel excavator, the first set of actions may include a bucket-opening action, and the preset threshold set may include a first threshold. If the action in the first set of actions corresponding to the action signal is a bucket-opening action, and the value of the action signal is greater than the first threshold, then the current action of the target excavator can be determined as the target action. For example, Figure 2 This is a schematic diagram of the current value of the action electrical signal of the target excavator during the bucket opening process provided in an embodiment of the present invention, as shown in the figure. Figure 2 As shown, the horizontal axis represents time (unit: seconds), and the vertical axis represents current (unit: milliamperes). Based on the action attribute label of this action signal, it can be identified that the action signal is a bucket opening signal, that is, the action corresponding to the action signal is the bucket opening action. The curves between points ① and ② in the figure all represent action signals with current values ​​greater than the first threshold of 400 milliamperes. Therefore, it can be determined that all actions of the target excavator within the time period corresponding to points ① and ② are target actions.

[0067] In the above embodiments, by determining the current action of the target excavator as the target action when the action corresponding to the action electrical signal is the bucket opening action and the value of the action electrical signal is greater than the first threshold, the influence of abnormal operation or other irrelevant actions on determining the current number of buckets of the target excavator is eliminated.

[0068] In one embodiment, the first set of actions includes a slewing action, an unloading action, and a slewing-unloading action, and the preset threshold set includes a second threshold and a third threshold.

[0069] The step of determining the current action of the target excavator as the target action when the action corresponding to the action electrical signal is an action in the first action set and the value of the action electrical signal is greater than the corresponding threshold in the preset threshold set includes:

[0070] When the action corresponding to the action electrical signal is the rotary action and the value of the action electrical signal is greater than the second threshold; or,

[0071] When the action corresponding to the action electrical signal is the unloading action and the value of the action electrical signal is greater than the third threshold; or,

[0072] When the action corresponding to the action signal is the slewing unloading action, and the value of the first action signal in the action signal corresponding to the slewing action in the slewing unloading action is greater than the second threshold, and the value of the second action signal in the action signal corresponding to the unloading action in the slewing unloading action is greater than the third threshold;

[0073] The current action of the target excavator is determined to be the target action.

[0074] Specifically, when the target excavator is a backhoe excavator, the first set of actions may include a slewing action, an unloading action, and a slewing-unloading action. The preset threshold set may include a second threshold and a third threshold. The slewing action corresponds to the second threshold, and the unloading action corresponds to the third threshold. If the action corresponding to the action electrical signal is a slewing action and the value of that action electrical signal is greater than the second threshold, the current action of the target excavator can be determined as the target action. Alternatively,

[0075] If the action corresponding to the action signal is an unloading action and the value of the action signal is greater than the third threshold, then the current action of the target excavator can be determined as the target action. Alternatively,

[0076] If the action corresponding to the action signal is a slewing unloading action, and the value of the first action signal in the action signal corresponding to the slewing action in the slewing unloading action is greater than the second threshold, and the value of the second action signal in the action signal corresponding to the unloading action in the slewing unloading action is greater than the third threshold, then the current action of the target excavator can be determined as the target action.

[0077] In the above embodiments, by determining the current action of the target excavator as the target action when the action corresponding to the action signal is an action in the first action set and the value of the action signal is greater than the corresponding threshold in the preset threshold set, the negative influence of abnormal operation or other irrelevant actions on determining the current number of buckets of the target excavator is eliminated.

[0078] In one embodiment, the excavator bucket count identification method further includes:

[0079] If the action corresponding to the action signal is an action in the first action set and the value of the action signal is less than or equal to the corresponding threshold in the preset threshold set, then the current action of the target excavator is determined to be a non-target action.

[0080] If the current action is the non-target action, the number of consecutive executions of the target action at the current moment is recorded as zero.

[0081] Specifically, if the action corresponding to the action signal is an action in the first action set and the value of the action signal is less than or equal to the corresponding threshold in the preset threshold set, it indicates that the current action of the target excavator may be an abnormal operation, and thus it can be determined that the action is a non-target action. In the case that the current action is a non-target action, the number of consecutive executions of the target action at the current moment can be recorded as zero.

[0082] For example, if the target excavator's current action at 18:16:00 is a non-target action, the number of consecutive executions of the target action at that time can be recorded as 0. If the target excavator's current action at 18:16:01 is a target action, the number of consecutive executions of the target action at that time can be recorded as 1. If the target excavator's current action at 18:16:02 is a target action, the number of consecutive executions of the target action at that time can be recorded as 2. If the target excavator's current action at 18:16:03 is a non-target action, the number of consecutive executions of the target action at that time can be recorded as 0.

[0083] In the above embodiments, if the action corresponding to the action signal is an action in the first action set and the value of the action signal is less than or equal to the corresponding threshold in the preset threshold set, the current action of the target excavator is determined to be a non-target action. Furthermore, if the current action is a non-target action, the number of consecutive executions of the target action at the current moment is recorded as zero. This ensures that the current bucket count of the target excavator can be correctly determined in subsequent processes.

[0084] Step 130: Determine the current number of buckets of the target excavator based on the number of consecutive executions of the target action at each time point.

[0085] In one embodiment, determining the current bucket count of the target excavator based on the number of consecutive executions of the target action at each time step includes:

[0086] Identify the number of consecutive executions of the target action at each time point, and determine that the target excavator has completed one bucket if the number of consecutive executions is equal to a preset threshold.

[0087] Based on the number of times the target excavator completes one bucket within a preset time period, the current number of buckets of the target excavator within the preset time period is determined.

[0088] Specifically, when the target excavator is a front shovel excavator and the target action is a bucket-opening action, the cloud server can identify the number of consecutive executions of the target action at each moment. If the number of consecutive executions equals a preset threshold, it is determined that the target excavator has completed one bucket. The preset threshold can be set according to the model of the target excavator and the corresponding working conditions. This embodiment of the invention does not impose specific limitations on it here.

[0089] For example, if the target action for the target excavator is the bucket-opening action, and a preset threshold number of executions is set to 8, then the consecutive execution counts of the target action for the target excavator from 18:16:00 to 18:16:10 on a certain day are 0, 1, 0, 1, 2, 3, 4, 5, 6, 7, and 8 respectively. Therefore, at 18:16:10, the consecutive execution count of the target action equals the preset threshold number, and at this point, it is determined that the target excavator has completed one bucket. Furthermore, based on the number of times the target excavator completes one bucket within a preset time period, the current bucket count of the target excavator within that preset time period can be determined. The preset time period can be determined as needed, and this embodiment of the invention does not impose a specific limitation. For example, the preset time period can be one day, such as January 1, 2024. If the target excavator completes one bucket 775 times on that day, then the current bucket count of the target excavator at the end of the preset time period is determined to be 775.

[0090] In the above embodiments, the number of consecutive executions of the target action at each moment is identified. When the number of consecutive executions is equal to a preset threshold, it is determined that the target excavator has completed one bucket. Then, based on the number of times the target excavator has completed one bucket within a preset time period, the current number of buckets of the target excavator within the preset time period is determined, which improves the efficiency and accuracy of recording the number of buckets worked by the excavator. Experiments have shown that, for front shovel excavators, the accuracy of determining the current number of buckets of the target excavator within a preset time period based on the method provided in this embodiment can reach more than 98%.

[0091] In one embodiment, determining the current bucket count of the target excavator based on the number of consecutive executions of the target action at each time step includes:

[0092] Based on the number of consecutive executions of the rotation action and the unloading action in the target action at each time point, the completion status of the rotation action and the unloading action is determined.

[0093] Based on the completion status of the slewing action and the unloading action, if a set of the slewing action and the unloading action are completed sequentially or simultaneously, it is determined that the target excavator has completed one bucket.

[0094] Based on the number of times the target excavator completes one bucket within a preset time period, the current number of buckets of the target excavator within the preset time period is determined.

[0095] Specifically, when the target excavator is a backhoe excavator, the cloud server can determine the completion status of the slewing and unloading actions based on the consecutive execution counts of each action at each moment. Furthermore, based on the completion status of the slewing and unloading actions, it can be determined that the target excavator has completed one bucket if a set of slewing and unloading actions are completed sequentially or simultaneously. Further, based on the number of times the target excavator completes one bucket within a preset time period, the current number of buckets completed by the target excavator within that preset time period can be determined.

[0096] Optionally, the cloud server can also pre-build action queues corresponding to the target actions at each time point, with each action queue reflecting the completion status of its respective target action. For example, if the number of consecutive executions of the rotation action at a given time point equals a first preset threshold, only the symbol T corresponding to the rotation action can be input into the action queue corresponding to the target action at that time point. Similarly, if the number of consecutive executions of the unloading action at a given time point equals a second preset threshold, only the symbol U corresponding to the unloading action can be input into the action queue corresponding to the unloading action at that time point. The action queue corresponding to the target action at the next time point can be determined based on the action queue corresponding to the target action at the previous time point. If the number of symbols in the action queue corresponding to the target action at the previous time point is two or zero, the symbols in the action queue corresponding to the target action at the next time point are determined solely based on the number of consecutive executions of the rotation action and the unloading action at the next time point. If the number of symbols in the action queue corresponding to the target action at the previous time step is equal to one, the symbols in the action queue corresponding to the target action at the next time step are determined based on the symbols in the action queue corresponding to the target action at the previous time step, as well as the consecutive execution counts of the slewing action and the unloading action at the next time step. That is, while retaining the symbols in the action queue at the previous time step, the decision to add new symbols is based on the consecutive execution counts of the slewing action and the unloading action. If the symbol type in the action queue is TU or UT, then it is determined that the target excavator has completed one bucket.

[0097] For example, if the first and second preset thresholds are both set to 8, and at 18:16:10 on a certain day, the number of consecutive executions of the slewing action is 8, and the number of consecutive executions of the unloading action is 6, then the symbol T corresponding to the slewing action is input into the action queue. At this time, the symbol type in the action queue is T. At 18:16:11, the number of consecutive executions of the slewing action is 9, and the number of consecutive executions of the unloading action is 7. At this time, the symbol type in the action queue is still T. At 18:16:12, the number of consecutive executions of the slewing action is 0, and the number of consecutive executions of the unloading action is 8, then the symbol U corresponding to the unloading action is input into the action queue. At this time, the symbol type in the action queue is TU. Once it is determined that the target excavator has completed one bucket, the symbol in the action queue is cleared, and there are no symbols in the action queue after the clearing.

[0098] In the above embodiments, based on the completion status of the slewing and unloading actions, when a set of slewing and unloading actions are completed sequentially or simultaneously, it is determined that the target excavator has completed one bucket. Based on the number of times the target excavator completes one bucket within a preset time period, the current bucket count of the target excavator within the preset time period is determined, which improves the efficiency and accuracy of recording the excavator's working bucket count. Experiments have shown that, for backhoe excavators, the accuracy rate of determining the current bucket count of the target excavator within a preset time period based on the method provided in this embodiment can reach over 95%.

[0099] This invention provides a method for identifying the number of buckets working on an excavator. First, it acquires the real-time electrical signals of the target excavator's movements. Then, based on these signals, it determines the current movement of the target excavator. If the current movement is the target movement, it records the number of consecutive executions of the target movement at the current moment. Finally, based on the number of consecutive executions of the target movement at each moment, it determines the current number of buckets working on the target excavator. This invention achieves automatic identification of the number of buckets working on an excavator by acquiring the target excavator's electrical signals in real time, eliminating the need for manual recording of bucket counts, reducing labor costs, and improving work efficiency and accuracy compared to manual recording.

[0100] In one embodiment, the excavator bucket count identification method further includes:

[0101] The current number of buckets of the target excavator is displayed in real time.

[0102] Specifically, the cloud server can display the current number of buckets of the target excavator in real time. Figure 3 This is one of the schematic diagrams provided in this embodiment of the invention for real-time display of the current bucket count of a target excavator. When the target excavator is a front shovel excavator, the real-time display of the target excavator's current bucket count can be as follows: Figure 3 As shown. Figure 4This is the second schematic diagram of real-time display of the current bucket count of a target excavator provided in this embodiment of the invention. When the target excavator is a backhoe excavator, the real-time display of the target excavator's current bucket count can be as follows: Figure 4 As shown.

[0103] In the above embodiments, the current number of buckets of the target excavator is displayed in real time, making the current number of buckets of the target excavator visible and facilitating managers to observe the number of buckets of the target excavator in real time.

[0104] Optionally, the production coefficient can be determined based on the duration of a historical preset time period, the output of the target excavator within the historical preset time period, and the number of buckets of the target excavator at a historical moment; then, the output of the target excavator within the preset time period can be determined based on the production coefficient and the number of buckets of the target excavator within the preset time period. That is, the production coefficient multiplied by the number of buckets of the target excavator within the preset time period equals the output of the target excavator within the preset time period.

[0105] Furthermore, the energy efficiency ratio of the target excavator within a preset time period can be determined by combining the output of the target excavator within the preset time period with its fuel consumption or electricity consumption within the preset time period. Specifically, the energy efficiency ratio of the target excavator within the preset time period is equal to the output of the target excavator within the preset time period divided by its fuel consumption or electricity consumption within the preset time period.

[0106] Alternatively, the working efficiency of the target excavator within a preset time period can be determined based on the number of buckets used by the target excavator within that time period. This allows managers to clearly understand the daily working efficiency and energy efficiency ratio of the target excavator, facilitating excavator management.

[0107] For example, taking a preset time period of one day and a first threshold of 400 mA as an example, the excavator bucket count recognition method can also be described using Groovy syntax. Figure 5 This is the second flowchart illustrating the excavator bucket count recognition method provided in this embodiment of the invention. It describes the process using Groovy syntax for the excavator bucket count recognition method when the target excavator is a front shovel excavator. For example... Figure 5 As shown, the bucket opening signal in the electrical signals of the target excavator's actions can be acquired in real time. The bucket opening signal is denoted as `dumpopen`, and the number of consecutive bucket openings is denoted as `Number_of_buckets`. When the value of the bucket opening signal is greater than a first threshold of 400, the number of consecutive bucket openings `Number_of_buckets` is incremented by 1. When the value of the bucket opening signal is less than or equal to the first threshold of 400, the number of consecutive bucket openings `Number_of_buckets` is set to zero. The above process can be described using Groovy syntax, resulting in the following code:

[0108]

[0109] Here, $lastState() represents the state of the content within the parentheses at the previous moment.

[0110] Let A_bucket_or_not denote whether the target excavator has completed one bucket. If the number of consecutive bucket runs (Number_of_buckets) equals a preset threshold of 8, then the target excavator has completed one bucket. A_bucket_or_not can be represented using Groovy syntax as follows:

[0111]

[0112] Let the current bucket count of the target excavator be denoted as Cumulative_buckets_shovel. If the current bucket count of the target excavator at the current moment is on a different date than the bucket count of the target excavator at the previous moment, then the Cumulative_buckets_shovel for the current date will be accumulated. The above process can be described using Groovy syntax as follows:

[0113]

[0114] Where Current_date represents the current date.

[0115] For example, taking a preset time period of one day and both the second and third thresholds of 400 mA as an example, the excavator bucket count recognition method can also be described using Groovy syntax. Figure 6 This is the third flowchart illustrating the excavator bucket count identification method provided in this embodiment of the invention. It describes the process using Groovy syntax for the excavator bucket count identification method when the target excavator is a backhoe excavator. For example... Figure 6As shown, the swing signal from the target excavator's electrical signals can be acquired in real time, denoted as "turn," and the number of consecutive swings is denoted as "Number_of_turns." The unloading signal from the target excavator's electrical signals can also be acquired in real time, denoted as "unload," and the number of consecutive unloadings is denoted as "Number_of_dunloads." When the value of the swing signal is greater than the second threshold of 400, the number of consecutive swings (Number_of_turns) is incremented by 1; when the value of the swing signal is less than or equal to the second threshold of 400, the number of consecutive swings (Number_of_turns) is set to zero. When the value of the unloading signal is greater than the third threshold of 400, the number of consecutive unloadings (Number_of_dunloads) is incremented by 1; when the value of the unloading signal is less than or equal to the third threshold of 400, the number of consecutive unloadings (Number_of_dunloads) is set to zero. The above process can be described using Groovy syntax, resulting in the following code:

[0116]

[0117] Let the action queue be denoted as `Action_queue`. When the action queue is empty or the number of symbols in the action queue is two or zero, check if the number of consecutive spins equals a first preset threshold, and check if the number of consecutive unloads equals a second preset threshold. If the number of consecutive spins (`Number_of_turns`) equals the first preset threshold of 8, the spin action is valid, and the symbol T corresponding to the spin action is input into the action queue. If the number of consecutive unloads (`Number_of_unloads`) equals the second preset threshold of 8, the unload action is valid, and the symbol U corresponding to the unload action is input into the action queue. The above process can be described using Groovy syntax as follows:

[0118]

[0119] Here, length() represents the number of symbols in the action queue, and null represents an empty queue.

[0120] When the action queue is empty or contains only one symbol, determine if the number of consecutive turns equals a first preset threshold and if the number of consecutive unloads equals a second preset threshold. If the number of consecutive turns (Number_of_turns) equals the first preset threshold of 8, input the symbol T corresponding to the turn action into the action queue and merge T with the symbol corresponding to the previous action. Alternatively, if the number of consecutive unloads (Number_of_unloads) equals the second preset threshold of 8, input the symbol U corresponding to the unload action into the action queue and merge U with the symbol corresponding to the previous action. If the number of consecutive turns (Number_of_turns) does not equal the first preset threshold of 8 and the number of consecutive unloads (Number_of_unloads) does not equal the second preset threshold of 8, retain the symbol corresponding to the previous action. The above process can be described using Groovy syntax as follows:

[0121]

[0122] Let `Cumulative_buckets` represent the current bucket count of the target excavator. If the current bucket count and the previous bucket count are on the same date and the symbol type in the action queue is TU or UT, then `Cumulative_buckets` is incremented by 1. If the current bucket count and the previous bucket count are on different dates, then it checks if the symbol type in the action queue is TU or UT. If the symbol type is TU or UT, then `Cumulative_buckets` is set to 1; otherwise, it is set to 0. The above process can be described using Groovy syntax as follows:

[0123]

[0124] Optionally, when the target excavator is a backhoe excavator, the digging signal in the action electrical signal of the target excavator can be acquired in real time, and the digging signal is denoted as dig, and the number of consecutive diggings is denoted as Number_of_digs. Then, the number of buckets of the target excavator can be determined by combining the number of consecutive diggings, the number of consecutive slewings, and the number of consecutive unloadings.
