[0002] A loader is a piece of machinery used for shoveling and loading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. With the rapid development of manufacturing technology for loaders and other construction machinery, loaders can also be equipped with different auxiliary working devices to perform bulldozing, lifting, and material loading and unloading operations, making loaders applicable to earthwork construction scenarios in highways, railways, buildings, hydropower, ports, and mines.

[0003] Loaders perform multiple consecutive actions during operation, each requiring control of operational data such as bucket speed, angle, and height to unload materials to a designated location. However, the operational data for each action is manually adjusted based on the user's experience, leading to inaccuracies and reduced efficiency. Furthermore, inaccurate manual adjustments can cause bucket collisions and tilting, further compromising the loader's overall efficiency. Summary of the Invention

[0053] Figure 1The illustration shows a schematic flowchart of a machine control method according to an embodiment of this application. Figure 1 As shown in the figure, this application provides a method for controlling a work machinery, which may include the following steps.

[0054] S110, acquires the operating data of the operating machinery;

[0055] During the operation of the machinery, operational data is acquired. It should be understood that the type of operational data is set according to actual needs and is not limited here. For ease of understanding, the operational data in the embodiments of this application includes the machinery's position information, motion information, load information, operation information, and time information.

[0056] The type of operating machinery is set according to actual needs and is not limited here. For ease of understanding, in the embodiments of this application, the operating machinery is a loader; the position information can be the position coordinates of the operating machinery, the bucket tilt angle, and the boom tilt angle, etc.; the motion information can be the loader's travel speed and direction of movement, etc.; the load information can be the bucket load, the throttle opening, the brake pedal opening, the travel motor speed, the travel motor torque, and the hydraulic pressure of the hydraulic device, etc.; the operation information can be the received control signal; the time information can be the time of each piece of operating data, which will not be elaborated here.

[0057] S120 determines the operating conditions of the machinery based on operational data, including loading, lifting, transporting, and unloading conditions.

[0058] When the operating condition of the machinery is loading, the characteristic movement is that the bucket lowers to approach or contact the ground. When the operating condition is lifting, the characteristic movement is that the bucket rises and tilts backward. When the operating condition is transporting, the bucket no longer performs digging or lifting movements; the characteristic movement is that the bucket remains relatively horizontal, and the tilt angle of the machinery changes little. When the operating condition is unloading, the bucket tilts backward to unload material, and the characteristic movement is that the bucket lifts to the preset unloading height. The different characteristic movements of the machinery under different operating conditions result in different operating data. Based on the acquired operating data, the operating condition of the machinery is determined.

[0059] S130, based on the operating conditions of the machinery, determines the control strategy for the machinery.

[0060] When operating machinery is in operation, it actively identifies the working conditions and determines the control strategy based on these conditions. Differentiated control strategies are provided for different working conditions, enabling refined control of the machinery, improving its working efficiency under various conditions, reducing energy consumption, and thus extending its service life.

[0061] S140, Obtain optimization information for controlling the operating machinery based on the control strategy;

[0062] Typically, during a loading cycle, the operating conditions of the machinery will switch between loading, lifting, transporting, and unloading modes. Within a loading cycle, a control strategy is used to manage these different operating conditions, and optimization information for the control strategy is obtained during the process. The type of optimization signal is set according to actual needs and can include adjusting parameter values; no specific limitation is made here.

[0063] In the embodiments of this application, obtaining optimization information for controlling the operating machinery based on a control strategy includes:

[0064] To obtain the operating efficiency and operating time of the machinery based on the control strategy;

[0065] Optimization information is obtained based on operating efficiency and running time.

[0066] In the process of controlling the operating machinery based on the control strategy, the operating efficiency and operating time of a loading cycle are obtained. Based on the operating efficiency and operating time, the working efficiency of the operating machinery is evaluated, and optimization information is obtained to improve working efficiency. The control strategy of the operating machinery is updated based on the optimization information. The operating machinery continuously optimizes the control strategy during operation, thereby enabling it to operate at maximum efficiency based on the updated control strategy.

[0067] S150 updates the control strategy of the operating machinery based on the optimization information, and controls the operating machinery based on the updated control strategy.

[0068] Even when controlling machinery using control strategies, situations may still arise where the machinery's efficiency doesn't reach its maximum. After completing the loading, lifting, transporting, and unloading operations within a loading cycle, the control strategy is updated based on optimization information. When the machinery enters the next loading cycle, the updated control strategy is used to re-perform the loading, lifting, transporting, and unloading operations, further improving efficiency. By continuously optimizing the control strategy during operation, the machinery can operate at peak efficiency based on the updated strategy.

[0069] In the embodiments of this application, the operating machinery includes a throttle, a bucket, a travel motor, and a hydraulic device. The operating data includes the throttle opening, the bucket load, the travel motor torque, the operating machinery travel speed, the hydraulic pressure of the hydraulic device, the bucket lifting height, and the bucket angle.

[0070] Based on operational data, determine the operating conditions of the machinery, including:

[0071] When the throttle opening is greater than the preset throttle opening, the bucket load is greater than the preset load, the travel motor torque is greater than the preset motor torque, and the machine's travel speed is less than the preset travel speed, the machine's working condition is determined to be the loading condition.

[0072] When a lifting control signal for the bucket is received, the hydraulic pressure of the hydraulic device is greater than the first preset pressure, and the lifting height of the bucket is greater than the preset height, the working condition of the working machine is determined to be the lifting condition.

[0073] If the change in the bucket lifting height is less than the preset change in height, the change in the bucket angle is less than the preset change in angle, and the travel speed of the working machine is greater than or equal to the preset speed, the working condition of the working machine is determined to be the transport working condition.

[0074] When the hydraulic pressure of the hydraulic device is less than the second preset pressure, the lifting height of the bucket is greater than the preset height, the angle of the bucket is less than the preset angle, and the load on the bucket is reduced, the working condition of the working machine is determined to be the unloading condition, wherein the first preset pressure is greater than the second preset pressure.

[0075] When the operating machinery is a loader, it includes a throttle, bucket, travel motor, and hydraulic system. Operating data includes throttle opening, bucket load, travel motor torque, operating machinery speed, hydraulic system pressure, bucket lifting height, and bucket angle. It's important to understand that the acquired operating data can be preprocessed to determine the operating condition of the machinery. The preprocessing steps are set according to actual needs and may include data cleaning to remove noise and missing values, or feature extraction to standardize the features of the operating data; no specific limitations are specified here.

[0076] For loading operations, the characteristics that the operating machinery needs to identify include the bucket load, throttle opening, machine travel speed, and travel motor torque. The preset throttle opening, preset load, preset motor torque, and preset travel speed values ​​are all set according to actual needs and are not limited here. For ease of understanding, in the embodiments of this application, the operating condition of the operating machinery is determined to be loading when the throttle opening is greater than 90%, the bucket load is greater than 50%, the travel motor torque is greater than the preset motor torque, and the machine travel speed is less than 5 km / h.

[0077] For lifting operations, the characteristics that the operating machinery needs to identify include the control signal of the control handle, the lifting height of the bucket, and the hydraulic pressure of the hydraulic device. The values ​​of the first preset pressure and preset height are set according to actual needs and are not limited here. For ease of understanding, in the embodiments of this application, when a lifting control signal for the bucket is received, the hydraulic pressure of the hydraulic device is greater than 20M, and the lifting height of the bucket is greater than 1 meter, the operating condition of the operating machinery is determined to be a lifting operation.

[0078] For transportation operations, the characteristics that need to be identified for the operating machinery include its travel speed, gear status, bucket load, and throttle opening. The operating condition of the operating machinery is determined to be transportation operation when the change in bucket lifting height is less than a preset change in height, the change in bucket angle is less than a preset change in angle, and the travel speed of the operating machinery is greater than or equal to 5 km / h.

[0079] For unloading conditions, the features that the operating machinery needs to identify include unloading time, bucket position, hydraulic pressure of the hydraulic system, and bucket load. The second preset pressure and preset angle are set according to actual needs and are not limited here. For ease of understanding, in the embodiments of this application, the operating condition of the operating machinery is determined to be unloading condition when the hydraulic pressure of the hydraulic system is less than 5M, the bucket lifting height is greater than 1 meter, the bucket angle is less than 0°, and the bucket load is reduced.

[0080] In the embodiments of this application, the control strategy for the operating machinery is determined based on its operating conditions, including:

[0081] When the working condition of the operating machinery is loading, the control strategy of the operating machinery is determined to be the first control strategy, wherein the first control strategy includes adjusting the torque of the travel motor to the maximum torque.

[0082] When the working condition of the working machinery is lifting, the control strategy of the working machinery is determined to be the second control strategy. The second control strategy includes adjusting the lifting speed of the bucket and the output power of the travel motor according to the load of the bucket.

[0083] When the working condition of the operating machinery is transportation condition, the control strategy of the operating machinery is determined to be the third control strategy, wherein the third control strategy is to adjust the travel speed of the operating machinery and the torque of the travel motor according to the load of the bucket.

[0084] When the working condition of the machine is unloading, the control strategy of the machine is determined to be the fourth control strategy, which includes adjusting the descent speed of the bucket based on a preset speed range.

[0085] When the operating condition of the machinery is loading, the control strategy for the machinery is determined to be the first control strategy. During the loading process based on the first control strategy, the torque of the travel motor is adjusted to its maximum, and the output power of the travel motor is P = T. max *n / 9550, where P is the output power of the walking motor, and T max Here, 'n' represents the maximum torque of the travel motor, and 'n' represents the speed of the travel motor. The adjusted speed of the travel motor does not exceed a preset percentage of the peak speed. By adjusting the torque of the travel motor to its maximum, the loading efficiency of the machinery is improved. It is important to understand that when the torque of the travel motor is adjusted to its maximum, the output power curve of the travel motor can be adjusted by changing its speed.

[0086] When the operating condition of the machinery is lifting, the control strategy for the machinery is determined to be the second control strategy. During the lifting process, the load on the bucket will change. Based on the load on the bucket, the lifting speed of the bucket and the output power of the travel motor are adjusted.

[0087] When the operating condition of the machinery is transportation mode, the control strategy for the machinery is determined to be the third control strategy. During the transportation mode of the machinery controlled by the third control strategy, different road conditions will result in different bucket loads. Based on the bucket load, the bucket lifting speed and the output power of the travel motor are adjusted.

[0088] When the operating condition of the machinery is unloading, the control strategy for the machinery is determined to be the fourth control strategy. During the unloading process, based on this fourth control strategy, the bucket descent speed is adjusted according to a preset speed range. It's important to understand that the preset speed range is set based on actual needs and is not limited here. Under unloading conditions, the bucket load is relatively small, so a higher preset speed range can be used to increase the bucket descent speed, thereby achieving rapid unloading.

[0089] In the embodiments of this application, the lifting conditions include heavy-load lifting conditions and light-load lifting conditions. Upon receiving a lifting control signal from the bucket, if the hydraulic pressure of the hydraulic device is greater than a first preset pressure and the lifting height of the bucket is greater than a preset height, the working condition of the operating machinery is determined to be a lifting condition, including:

[0090] Upon receiving a lifting control signal for the bucket, if the hydraulic pressure of the hydraulic device is greater than the first preset pressure and the lifting height of the bucket is greater than the preset height, determine whether the load on the bucket is greater than the preset load.

[0091] When the load on the bucket exceeds the preset load, the working condition of the machine is determined to be a heavy-load lifting condition.

[0092] When the load on the bucket is less than or equal to the preset load, the working condition of the machine is determined to be a light-load lifting condition.

[0093] In this embodiment, the lifting conditions include heavy-load lifting conditions and light-load lifting conditions. When a lifting control signal for the bucket is received, the hydraulic pressure of the hydraulic device is greater than a first preset pressure, and the lifting height of the bucket is greater than a preset height, the working condition of the working machine is determined to be the lifting condition, and it is determined whether the load of the bucket is greater than the preset load.

[0094] When the bucket load exceeds the preset load, the operating condition of the machine is determined to be heavy-load lifting. Based on the bucket load, the lifting speed of the bucket can be reduced and the output power of the travel motor increased. When the bucket load is less than or equal to the preset load, the operating condition of the machine is determined to be light-load lifting. Based on the bucket load, the lifting speed of the bucket can be increased and the output power of the travel motor reduced.

[0095] In the embodiments of this application, the transportation conditions include heavy-load transportation conditions and light-load transportation conditions. When the change in the bucket's lifting height is less than a preset height change value, the change in the bucket's angle is less than a preset angle change value, and the operating speed of the working machinery is greater than or equal to a preset speed, the operating condition of the working machinery is determined to be a transportation condition, including:

[0096] If the change in the bucket's lifting height is less than the preset change in height, the change in the bucket's angle is less than the preset change in angle, and the operating speed of the machinery is greater than or equal to the preset speed, determine whether the load on the bucket is greater than the preset load.

[0097] When the load on the bucket exceeds the preset load, the working condition of the machine is determined to be a heavy-load transportation condition.

[0098] When the load on the bucket is less than or equal to the preset load, the operating condition of the working machine is determined to be a light-load transportation condition.

[0099] In this embodiment, the transportation conditions include heavy-load transportation conditions and light-load transportation conditions. When the change in the lifting height of the bucket is less than the preset change in height, the change in the angle of the bucket is less than the preset change in angle, and the travel speed of the working machine is greater than or equal to the preset speed, the working condition of the working machine is determined to be the transportation condition, and it is determined whether the load of the bucket is greater than the preset load.

[0100] When the load on the bucket is less than or equal to the preset load, the operating condition of the machinery is determined to be light-load transport condition. Typically, the machinery operates in light-load transport condition when traveling on a flat road. The third control strategy corresponding to light-load transport condition can be that the machinery's travel speed does not exceed 15 km / h, the output power of the travel motor is P = T*n / 9550, where P is the output power of the travel motor, T is the torque of the travel motor (not exceeding 50% of its maximum torque), and n is the speed of the travel motor (adjusted to reach its peak speed).

[0101] When the operating machinery travels on uneven roads, it is in heavy-load transportation mode. The third control strategy corresponding to heavy-load transportation mode can be that the traveling speed of the operating machinery does not exceed 5km / h, the output power of the travel motor is P=T*n / 9550, where P is the output power of the travel motor, T is the torque of the travel motor and does not exceed 55% of the maximum torque, n is the speed of the travel motor and the adjusted speed of the travel motor does not exceed a preset percentage of the peak speed.

[0102] In the embodiments of this application, updating the control strategy of the operating machinery based on optimization information, and controlling the operating machinery based on the updated control strategy, includes:

[0103] Determine all target working conditions corresponding to the optimization information, where the target working condition is any one of the following working conditions: loading, lifting, transportation, and unloading.

[0104] Based on the optimization information, update the control strategy corresponding to each target working condition to obtain the updated control strategy corresponding to the target working condition.

[0105] When the operating condition of the working machinery is the target operating condition, the working machinery is controlled based on the updated control strategy corresponding to the target operating condition.

[0106] In actual operation of machinery, it is not always necessary to update the control strategy for all operating conditions. In this embodiment, after obtaining the optimization information, all target operating conditions corresponding to the optimization information are determined, i.e., the operating conditions for which the control strategy needs to be updated are identified. Based on the optimization information, the control strategy corresponding to each target operating condition is updated to obtain the updated control strategy for each target operating condition.

[0107] A loading cycle includes loading, lifting, transporting, and unloading conditions, with the target condition being any one of these conditions. Specifically, when the machinery starts and enters the first loading cycle, the machinery is controlled based on the control strategy corresponding to each condition.

[0108] In subsequent loading cycles following the first loading cycle, the control strategy for each target working condition is updated based on optimization information, resulting in an updated control strategy for each target working condition. It is then determined whether the current working condition of the machine is the target working condition. If the machine is not in the target working condition, the machine is controlled based on the corresponding control strategy. If the machine is in the target working condition, the machine is controlled based on the updated control strategy for that condition. During operation, the control strategy is continuously optimized as the loading cycle of the machine changes, enabling the machine to operate with maximum efficiency based on the updated control strategy.

[0109] In the embodiments of this application, the machine control method further includes:

[0110] Responding to received operating condition commands, determine the target operating condition of the machinery;

[0111] Control the operating machinery based on the control strategy corresponding to the target working condition.

[0112] In the operation engineering of construction machinery, users can request the operating conditions of the construction machinery through operating condition commands. The construction machinery responds to the received operating condition commands, determining the target operating condition, which can be any one of the user-requested conditions: loading, lifting, transporting, or unloading. The construction machinery is then controlled based on the control strategy corresponding to the target operating condition. By allowing users to manually request the control strategy corresponding to the operating condition, the construction machinery can operate according to actual user needs, thereby improving its work efficiency.

[0113] This application provides a method for controlling construction machinery. The method includes: acquiring operating data of the construction machinery; determining the operating conditions of the construction machinery based on the operating data; determining a control strategy for the construction machinery based on the operating conditions; acquiring optimization information for controlling the construction machinery based on the control strategy; updating the control strategy for the construction machinery based on the optimization information; and controlling the construction machinery based on the updated control strategy. This method provides differentiated control strategies for different operating conditions of the construction machinery, achieving refined control and improving the working efficiency of the construction machinery under various conditions.
