[0038] In order to make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] The control method of the combine harvester provided by the embodiment of the present application can be applied to the controller of the target combine harvester. Please refer to Figure 1 , and the method includes the following steps:

[0040] S110, obtaining target parameters of the target combine harvester, where the target parameters include at least one of the collection loss rate, the grain breakage rate, and the grain cleanliness.

[0041] Among them, the collection loss rate can be understood as the proportion of the grain kernel particles that cannot be effectively collected during the harvesting process of the target combine harvester to the total grain kernels to be harvested. Optionally, the collection loss rate can be used to measure the performance of the target combine harvester. For example, the lower the collection loss rate, the better the performance of the target combine harvester.

[0042] Among them, the grain breakage rate can be understood as the proportion of the grain kernels damaged by mechanical action during the harvesting process of the target combine harvester. Optionally, the grain breakage rate can be used to measure the performance of the target combine harvester. For example, the lower the collection loss rate and the grain breakage rate, the better the performance of the target combine harvester.

[0043] Among them, the grain cleanliness can be understood as the cleanliness of the grain kernels after being harvested by the target combine harvester. Optionally, the grain cleanliness can be measured by the content of impurities in the grain kernels. For example, the lower the impurity content, the higher the grain cleanliness. The grain cleanliness can be used to measure the performance of the target combine harvester. For example, the higher the grain cleanliness, the better the performance of the target combine harvester.

[0044] Exemplarily, the target parameters of the target combine harvester can be obtained in real time or at regular intervals from the parameter acquisition end or the parameter generation end for collecting the target parameters of the target combine harvester, so as to be able to understand the current operation status of the target combine harvester in real time and provide a data basis for generating control instructions. It should be noted that the determination process of the target parameters can be implemented by at least one parameter determination method in the traditional technology, and the present application does not make any limitation on this.

[0045] It should be noted that at least one of the parameters such as the collection loss rate, the grain breakage rate, and the grain cleanliness can be obtained according to the actual situation, so as to selectively monitor and optimize the key parameters according to the actual operation requirements and environmental conditions, thereby achieving precise control and efficient operation. For example, in the case of pursuing high harvesting efficiency, the collection loss rate can be obtained to ensure that as many grain kernels as possible are collected. In the case of processing easily damaged crops, the grain breakage rate can be obtained to accurately grasp the operation situation of the target combine harvester. In the case where the processing enterprise has high requirements for the cleanliness of the grain kernels, the grain cleanliness can be obtained to measure whether the target combine harvester meets the operation standards.

[0046] It is understandable that the target combine harvester can also automatically calculate parameters such as the moisture content, yield per mu, and actual feeding amount of the grain kernels entering the target combine harvester to provide diverse information such as the quality of the grain kernels.

[0047] S120, generate a control instruction according to the target parameter and the parameter threshold corresponding to the target parameter; wherein, the control instruction includes at least one of an angle control instruction, a rotation speed control instruction, and a gap control instruction.

[0048] Among them, the parameter threshold corresponding to the target parameter can be understood as a preset parameter standard value or range, which is used to determine whether the target parameter (such as the aforementioned collection loss rate, grain breakage rate, grain cleanliness, etc.) is in a standard state, and accordingly generate a corresponding control instruction.

[0049] It should be noted that due to the different physical characteristics of different crops (such as grain size, weight, shape, hardness, etc.) and the environmental conditions during harvesting (such as humidity, maturity, lodging conditions, etc.), corresponding parameter thresholds need to be set according to different crop types. For example, when the crop is wheat, since the wheat grains are relatively small and easy to leak out from the sieve plate, a lower collection loss rate threshold can be set to ensure that the grains are fully collected. For example, the collection loss rate threshold for wheat can be set to 2%. Since the wheat grains are relatively fragile and easy to be damaged during the threshing process, a higher grain breakage rate threshold can be set to reduce mechanical damage to the wheat grains. For example, the grain breakage rate threshold for wheat can be set to 5%. The impurity content is relatively high during wheat harvesting, so a lower cleanliness threshold can be set to ensure the cleanliness of the wheat grains. For example, the grain cleanliness threshold for wheat can be set to 90%.

[0050] When the crop is corn, since the corn grains are relatively large and hard and not easy to leak out from the sieve plate, a lower collection loss rate threshold can be set. For example, the collection loss rate threshold can be set to 2%. Since the corn grains are relatively hard and not easy to be damaged, a lower breakage rate threshold can be set. For example, the grain breakage rate threshold for corn can be set to 3%. The impurity content is relatively low during corn harvesting and the cleaning effect is good, so a higher grain cleanliness threshold can be set. For example, the grain cleanliness threshold for corn can be set to 97%. Among them, the parameter threshold corresponding to the target parameter can be set or adjusted by those skilled in the art according to needs or experience, and the present application does not make any limitation thereto.

[0051] Exemplarily, the control instruction can be understood as an instruction generated after comparing the target parameters obtained in real time with the parameter thresholds corresponding to the preset target parameters, and is used to dynamically adjust the operating parameters of the combine harvester to optimize the operation quality and efficiency. The angle control instruction is mainly used to adjust the sieve plate angle and cutter bar angle of the combine harvester to optimize the collection and separation effect of grain kernels. The rotational speed control instruction mainly optimizes the operation effect of the harvester by controlling the rotational speeds of components such as the threshing cylinder and the fan, thereby improving the harvesting quality of grain kernels, reducing the loss rate, and reducing the breakage of grain kernels. The gap control instruction is used to control the gap between the threshing cylinder and the concave plate to optimize the threshing effect, reduce the breakage of grain kernels, and thus improve the harvesting quality and efficiency.

[0052] In a specific embodiment, the control instruction can be generated according to the magnitude relationship between the target parameters and the parameter thresholds corresponding to the target parameters. Multiple sensors can be equipped in the target combine harvester. The collection loss rate can be obtained by monitoring the amount of uncollected grain kernels through sensors installed on the sieve plate or discharge device, the kernel breakage rate can be obtained by monitoring the proportion of broken grain kernels through sensors installed in the threshing system or grain tank, and the kernel cleanliness can be obtained by monitoring the impurity content through sensors installed in the cleaning system. Therefore, the target parameters can be obtained, and further, the control instruction can be generated by comparing the magnitude relationship between the target parameters and the parameter thresholds corresponding to the target parameters.

[0053] S130, according to the control instruction, control and adjust the operating parameters of the target combine harvester.

[0054] Among them, the operating parameters can be understood as specific values or settings used to control and adjust the operating states of various components of the target combine harvester. The operating parameters directly affect the operation effect of the combine harvester, the harvesting quality of grain kernels, and the overall operating efficiency. By dynamically adjusting the operating parameters, the performance of the harvester can be optimized to adapt to different operating environments and crop conditions.

[0055] Exemplarily, after the control instruction is generated by the controller, it can be transmitted to the control unit of the actuator through the communication interface. For example, the control instruction can be transmitted to the control unit of the actuator by the embedded controller through serial communication or other means.

[0056] The control method of the above combine harvester obtains the target parameters of the target combine harvester, and automatically generates a control instruction for adjusting the operating parameters of the target combine harvester according to the target parameters and the parameter thresholds corresponding to the target parameters. Since the target combine harvester can automatically generate control instructions according to the target parameters in the actual operating environment, the generated control instructions can match the actual operating environment, improving the accuracy of the control instructions. Further, according to the more accurate control instructions, the operating parameters of the target combine harvester are automatically controlled and adjusted, further improving the accuracy and convenience of the operating parameter adjustment results, thereby effectively reducing grain kernel losses, reducing the kernel breakage rate, and improving the cleanliness of the kernels, and further improving the overall quality of grain kernel harvesting. In addition, the above process does not require manual intervention, can reduce the dependence on the experience of operators, and avoid problems such as improper parameter adjustment caused by mistakes in the manual adjustment process, ensuring the stability and consistency of the operating parameters.

[0057] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the step of generating a control instruction according to the target parameter and the parameter threshold corresponding to the target parameter in S120 is refined.

[0058] See Figure 2 The control instruction generation steps shown include:

[0059] S210, when the collected loss rate is greater than the collected loss rate threshold, generate a sieve plate angle control instruction and a fan speed reduction control instruction.

[0060] If the target parameter includes the collected loss rate, the parameter threshold corresponding to the target parameter correspondingly includes the collected loss rate threshold. The collected loss rate threshold can be understood as the maximum grain kernel loss rate allowed during the operation of the target combine harvester, and is used to determine whether the grain kernel loss of the current target combine harvester during the harvesting operation is within an acceptable range. Among them, the acceptable range can be set or adjusted by technicians according to needs or experience, and the present application does not make any limitation thereto.

[0061] Among them, the sieve plate angle control instruction can be understood as a control instruction for dynamically adjusting the angle of the sieve plate to achieve an optimized separation and cleaning effect of grain kernels. The adjustment of the sieve plate angle directly affects the residence time, flow velocity of grain kernels on the sieve plate, and the discharge effect of impurities, thereby affecting the operation quality and efficiency of the target combine harvester.

[0062] The control instruction for reducing the fan speed can be understood as a control instruction for dynamically reducing the fan speed to optimize the cleaning effect of grain kernels and reduce the collection loss rate. By reducing the fan speed, the risk of grain kernels being blown out can be reduced, thereby improving the harvesting efficiency and the quality of grain kernel collection.

[0063] Exemplarily, when the collection loss rate is greater than the collection loss rate threshold, it indicates that during the harvesting process of the target combine harvester, the proportion of grain kernel particles that cannot be effectively collected in the total grain kernels to be harvested is too large. The sieve plate angle control instruction and the control instruction for reducing the fan speed can be generated, and further, according to the sieve plate angle control instruction and the control instruction for reducing the fan speed, the relevant parameters of the target combine harvester can be controlled and adjusted to improve the harvesting efficiency and the quality of grain kernel collection.

[0064] S220, when the grain breakage rate is greater than the grain breakage rate threshold, generate a control instruction for the threshing cylinder speed and a control instruction for the gap between the threshing cylinder and the concave plate.

[0065] If the target parameter includes the grain breakage rate, the corresponding parameter threshold of the target parameter correspondingly includes the grain breakage rate threshold. The grain breakage rate threshold can be understood as the maximum allowable grain breakage rate during the operation of the target combine harvester, which is used to measure the degree of mechanical damage suffered by the grain kernels during the harvesting process. Among them, the acceptable range can be set or adjusted by technicians according to needs or experience, and the present application does not make any limitation thereto.

[0066] Among them, the control instruction for the threshing cylinder speed can be understood as a control instruction for dynamically adjusting the speed of the threshing cylinder to achieve the effect of optimizing the threshing effect and reducing the breakage of grain kernels. The speed of the threshing cylinder directly affects the threshing efficiency of grain kernels and the degree of mechanical damage to grain kernels. By precisely controlling the speed of the threshing cylinder, the harvesting quality and operation efficiency can be significantly improved.

[0067] The control instruction for the gap between the threshing cylinder and the concave plate can be understood as an instruction for dynamically adjusting the gap between the threshing cylinder and the concave plate. It can significantly optimize the threshing effect, reduce the grain breakage rate, and at the same time improve the cleanliness of grain kernels and the overall operation quality.

[0068] Exemplarily, when the grain breakage rate is greater than the grain breakage rate threshold, it indicates that the mechanical action during the current threshing process is too intense, resulting in excessive damage to the grain kernels. The control instruction for the threshing cylinder speed and the control instruction for the gap between the threshing cylinder and the concave plate can be generated. Further, according to the control instruction for the threshing cylinder speed and the control instruction for the gap between the threshing cylinder and the concave plate, the relevant parameters of the target combine harvester can be controlled and adjusted to improve the quality of grain kernel collection.

[0069] S230. Generate a control command to increase the fan speed when the grain cleanliness is less than the grain cleanliness threshold.

[0070] If the target parameter includes the grain cleanliness, the corresponding parameter threshold of the target parameter correspondingly includes the grain cleanliness threshold. The grain cleanliness threshold can be understood as the maximum percentage of impurity content allowed during the operation of the target combine harvester, which is used to determine whether the cleanliness of the cereal grains in the current harvesting operation reaches an acceptable standard. Among them, the acceptable range can be set or adjusted by technicians according to needs or experience, and the present application does not make any limitation thereto.

[0071] Among them, the control command to increase the fan speed can be understood as a control command for dynamically increasing the fan speed to achieve an optimized cleaning effect of the cereal grains. By increasing the fan speed, the fan speed can be raised, the wind force can be enhanced, so as to more effectively remove the impurities in the cereal grains and ensure the cleanliness of the cereal grains.

[0072] Exemplarily, when the grain cleanliness is less than the grain cleanliness threshold, it indicates that there are too many impurities in the cereal grains and the cleaning process needs to be optimized. A control command to increase the fan speed can be generated, and further, according to the control command to increase the fan speed, the relevant parameters of the target combine harvester can be controlled and adjusted to improve the cleanliness of the cereal grains.

[0073] In each of the above optional implementation manners, by comparing the target parameter with the corresponding parameter threshold of the target parameter, it can be determined whether the actual target parameter of the target combine harvester is within the acceptable standard range. When the actual target parameter exceeds the acceptable standard range, a control command corresponding to the target parameter is automatically generated, so that the generated control command can match the actual operating environment, improving the accuracy of the control command. Automatically generating the control command does not require manual shutdown adjustment, so it can reduce the shutdown adjustment problems caused by improper parameter settings, and further improve the practicability of the target combine harvester.

[0074] It should be noted that the above S210 - S230 can be executed sequentially or in parallel, and the present application does not make any limitation on the execution order of the three.

[0075] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the step of controlling and adjusting the operating parameters of the target combine harvester according to the control command in S130 is further refined.

[0076] See Figure 3 The shown operating parameter adjustment steps include:

[0077] S310. Increase the sieve plate angle of the sieve plate in the target combine harvester according to the sieve plate angle control instruction, and decrease the fan speed of the fan in the target combine harvester according to the fan speed reduction control instruction.

[0078] Exemplarily, the sieve plate angle of the sieve plate in the target combine harvester can be increased according to the sieve plate angle control instruction. Specifically, the sieve plate angle can be adaptively adjusted according to the parameters of the target combine harvester. The fan speed of the fan in the target combine harvester can be decreased according to the fan speed reduction control instruction. Specifically, the fan speed can be adaptively adjusted according to the parameters of the target combine harvester to reduce the collection loss rate.

[0079] It should be noted that the sieve plate angle and the fan speed can be adaptively adjusted according to the actual parameters of the target combine harvester, so that the adjusted sieve plate angle and the fan speed can work in coordination with each other to reduce the collection loss rate.

[0080] In some alternative implementation manners, by increasing the sieve plate angle of the sieve plate in the target combine harvester according to the sieve plate angle control instruction, the residence time of the grain kernels on the sieve plate can be increased, so that the grain kernels have more opportunities to enter the grain tank through the sieve holes, thereby reducing the risk of the grain kernels leaking out of the sieve plate. And decrease the fan speed of the fan in the target combine harvester according to the fan speed reduction control instruction. The wind force can be reduced to avoid the grain kernels being blown out of the sieve plate, further reducing the collection loss rate and ensuring the maximization of the collection amount of the grain kernels.

[0081] S320. Decrease the threshing cylinder speed of the threshing cylinder in the target combine harvester according to the threshing cylinder speed control instruction, and increase the gap between the threshing cylinder and the concave plate in the target combine harvester according to the concave plate gap control instruction.

[0082] Exemplarily, the threshing cylinder speed of the threshing cylinder in the target combine harvester can be decreased according to the threshing cylinder speed control instruction. Specifically, the threshing cylinder speed of the threshing cylinder can be adaptively adjusted according to the actual operating parameters of the target combine harvester. The gap between the threshing cylinder and the concave plate in the target combine harvester can be increased according to the concave plate gap control instruction. Specifically, the gap between the threshing cylinder and the concave plate can be adaptively adjusted according to the actual operating parameters of the target combine harvester to reduce the kernel breakage rate.

[0083] It should be noted that the threshing cylinder speed of the threshing cylinder and the gap between the threshing cylinder and the concave plate can be adaptively adjusted according to the actual operating parameters of the target combine harvester, so that the adjusted threshing cylinder speed of the threshing cylinder and the gap between the threshing cylinder and the concave plate can work in coordination with each other to reduce the kernel breakage rate.

[0084] In some alternative implementations, by automatically reducing the threshing cylinder speed of the target combine harvester according to the threshing cylinder speed control instruction, the mechanical force on the grain kernels during threshing can be reduced, thereby significantly reducing the kernel breakage rate. And according to the concave clearance control instruction, by automatically increasing the clearance between the threshing cylinder and the concave in the target combine harvester, the mechanical extrusion of the grain kernels during threshing can be reduced, further reducing the kernel breakage rate. By reducing the kernel breakage rate, problems such as damage to the grain kernels caused by mechanical damage can be reduced, thereby improving the quality of the grain kernels.

[0085] S330. Increase the fan speed of the fan in the target combine harvester according to the fan speed increase control instruction.

[0086] Exemplarily, the fan speed of the fan in the target combine harvester can be increased according to the fan speed increase control instruction. Specifically, the fan speed of the fan can be adaptively adjusted according to the actual operating parameters of the target combine harvester.

[0087] In some alternative implementations, by increasing the fan speed of the fan in the target combine harvester according to the fan speed increase control instruction, the wind force can be enhanced, and the impurities in the grain kernels can be blown out more effectively, thereby significantly improving the kernel cleanliness, ensuring that the grain kernels entering the grain tank meet the preset cleanliness standard, and reducing the costs of subsequent cleaning and processing. And the fan speed can be dynamically adjusted according to the cleaning effect requirements of different crops to better adapt to the cleaning needs of different crops. And by automatically controlling the target combine harvester, precise operation can be achieved, human intervention can be reduced, and the applicability of the target combine harvester can be enhanced.

[0088] In the above alternative implementations, by automatically generating and executing the control instructions by the controller, the dependence on the operator's experience can be reduced, thereby avoiding the problem of operation quality fluctuations caused by human factors. And by generating corresponding control instructions based on the actual working parameters of the target combine harvester and making adaptive adjustments to the target combine harvester through the corresponding control instructions, the operation quality of the target combine harvester can be improved. And by automatically making adaptive adjustments to the target combine harvester without manual shutdown for inspection, the time for parameter adjustment of the target combine harvester can be reduced, and the operation efficiency can be improved.

[0089] It should be noted that the above S310 - S330 can be executed sequentially or implemented in parallel, and the present application does not make any limitation on the execution order of the three.

[0090] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear indication in this article, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

The solution provided by this device to solve the problem is similar to the solution described in the above method. Therefore, the specific limitations in one or more embodiments of the control device for the combine harvester provided below can refer to the limitations on the control method of the combine harvester in the above text, and will not be repeated here.

[0093] The acquisition module 410 is configured to acquire target parameters of a target combine harvester, where the target parameters include at least one of a collection loss rate, a grain breakage rate, and a grain cleanliness.
