Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural harvesting machine control, in particular to a control method and device for a harvesting machine, a storage medium, a processor and a harvesting machine. BACKGROUND

[0002] In recent years, the total yield of crops in China has been increasing year by year, and the automation level of agricultural harvesting machines has been continuously improved. However, the loss rate and the impurity rate of agricultural harvesting machines have always been a big problem. The loss in the harvesting process of agricultural harvesting machines is mostly caused by the comprehensive action of factors such as the performance of the machine itself, the quality of machine maintenance, the level of manual operation, climate conditions, environmental factors, and the maturity of crops. The loss rate will affect the harvesting yield of the harvesting machine to some extent. At the same time, during the harvesting process of agricultural harvesting machines, due to the influence of environmental factors, the structure of the harvesting machine, and the characteristics of the harvesting machine, various impurities are often mixed in the harvested crops, which affects the harvesting quality of the harvesting machine to some extent.

[0003] In the current prior art, most of the methods for determining the loss rate lack scientificity, and some even need manual participation in estimation, resulting in a large error in the determination of the loss rate of the harvesting machine, so it is also difficult to reduce the loss rate to the ideal degree according to the determination result. Moreover, since the control factors of the loss rate and the impurity rate of the harvesting machine are related, the control algorithm currently adopted is also difficult to reduce both the loss rate and the impurity rate to the ideal degree.

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the embodiments of the present application, and are not intended to limit the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0034] Figure 1 Fig. 2 schematically shows a flowchart of a control method for a harvesting machine according to an embodiment of the present application. As shown in Fig. 2, in an embodiment of the present application, a control method for a harvesting machine is provided, including the following steps: Figure 1

[0035] Step 101, obtaining a loss rate and a foreign matter rate of the harvesting machine.

[0036] Step 102, determining that the harvesting machine is in a high-loss state when the loss rate is higher than a first preset threshold.

[0037] Step 103, adjusting an execution parameter of a component of the harvesting machine to reduce the loss rate of the harvesting machine.

[0038] Step 104, determining that the harvesting machine is in a high-foreign-matter state when the foreign matter rate is higher than a second preset threshold.

[0039] Step 105, adjusting an execution parameter of a component of the harvesting machine to reduce the foreign matter rate of the harvesting machine; wherein the component includes at least one of a fan of the harvesting machine, a tail sieve sheet of the harvesting machine, and an upper sieve sheet of the harvesting machine.

[0040] When the harvesting machine harvests crops, the loss rate and the foreign matter rate of the crops can be controlled. First, the processor can obtain the loss rate and the foreign matter rate of the crops harvested by the harvesting machine through the sensor. The loss rate can refer to the proportion of the difference between the ideal harvesting yield of the harvesting machine and the actual harvested crop yield to the ideal harvesting yield. The foreign matter rate can refer to the proportion of non-hazardous foreign matters in the crops harvested by the harvesting machine.

[0041] After obtaining the loss rate and the impurity rate, the processor can first compare the loss rate with a first preset threshold. In a case where it is determined that the loss rate is higher than the first preset threshold, the processor can determine that the harvester is in a high loss state. That is, the high loss state can refer to the state of the harvester when the loss rate is higher than the first preset threshold. The first preset threshold can be a value set according to a national standard or a lower standard than the national standard. In a case where it is determined that the harvester is in the high loss state, the processor can adjust the execution parameter of the component of the harvester to reduce the loss rate of the harvester when harvesting crops. In a case where the processor determines that the harvester is not in the high loss state after comparing the loss rate with the first preset threshold, the processor can determine whether the state of the harvester at this time is a high impurity state. The processor can compare the impurity rate with a second preset threshold. In a case where the impurity rate is higher than the second preset threshold, the processor can determine that the harvester is in the high impurity state. That is, the high impurity state can refer to the state of the harvester when the impurity rate is higher than the second preset threshold. The second preset threshold can be a value set according to a national standard or a lower standard than the national standard. In a case where it is determined that the harvester is in the high impurity state, the processor can adjust the execution parameter of the component of the harvester to reduce the impurity rate of the harvester.

[0042] The component of the harvester can include at least one of a fan of the harvester, a tail sieve sheet of the harvester, and an upper sieve sheet of the harvester. The execution parameter of the component of the harvester can be a fan speed of the harvester, a sieve sheet opening degree of the tail sieve sheet of the harvester, and a left-right opening degree of the upper sieve sheet of the harvester, etc. There can be one execution parameter corresponding to each component of the harvester. For example, when the component of the harvester is the fan of the harvester, the corresponding execution parameter can be the fan speed of the harvester. When the component of the harvester is the tail sieve sheet of the harvester, the corresponding execution parameter can be the sieve sheet opening degree of the tail sieve sheet of the harvester. When the component of the harvester is the upper sieve sheet of the harvester, the corresponding execution parameter can be the left-right opening degree of the upper sieve sheet of the harvester.

[0043] The above technical solution takes reducing the loss rate of the harvester as the first priority target, and realizes comprehensive control of the loss rate and the impurity rate of the harvester, greatly reducing the loss rate and the impurity rate of the harvester when harvesting crops, and improving the harvesting yield and the harvesting quality of the harvester. At the same time, by adjusting the execution parameter of the component of the harvester, errors caused by manual intervention or other environmental factors can be avoided, and the loss rate and the impurity rate of the harvester can be accurately controlled.

[0044] In one embodiment, the adjusting the execution parameters of the components of the harvester to reduce the loss rate of the harvester comprises: obtaining a fan rotating speed of the harvester; obtaining a sieve opening degree of a tail sieve of the harvester in a case that the fan rotating speed is a preset minimum fan speed; and controlling the sieve opening degree of the tail sieve to increase in a case that the sieve opening degree of the tail sieve is not a preset maximum opening degree.

[0045] In one embodiment, the control method further comprises: controlling a left-right opening degree of an upper sieve of the harvester to increase in a case that the sieve opening degree of the tail sieve is the preset maximum opening degree.

[0046] In a case that the harvester is in a high loss state, the processor can adjust the execution parameters of the components of the harvester to reduce the loss rate of the harvester. The execution parameters of the components of the harvester can include a fan rotating speed of the harvester, a sieve opening degree of an upper sieve of the harvester, and a sieve opening degree of a tail sieve of the harvester. Specifically, the processor can obtain the fan rotating speed of the harvester. In a case that the fan rotating speed is a preset minimum fan speed, the processor can obtain the sieve opening degree of the tail sieve of the harvester. The sieve opening degree can refer to an opening angle of the sieve. The preset minimum fan speed can refer to that the fan rotating speed of the harvester reaches a minimum value set by electro-hydraulic control. When the sieve opening degree of the tail sieve of the harvester reaches a minimum value set by electro-hydraulic control of the harvester, the sieve opening degree of the tail sieve can reach a maximum, and the processor can obtain a preset maximum opening degree of the tail sieve. After obtaining the sieve opening degree of the tail sieve of the harvester and the preset maximum opening degree, the processor can compare the sieve opening degree of the tail sieve with the preset maximum opening degree. In a case that the sieve opening degree of the tail sieve is not the preset maximum opening degree, the processor can control the sieve opening degree of the tail sieve to increase, i.e., to increase the opening angle of the tail sieve.

[0047] After comparing the sieve opening degree of the tail sieve with the preset maximum opening degree, in a case that the sieve opening degree of the tail sieve is the preset maximum opening degree, the processor can control a left-right opening degree of an upper sieve to increase, i.e., to increase the opening angle of the upper sieve.

[0048] In one embodiment, the control method further comprises: obtaining a last adjustment action for the fan in a case that the fan rotating speed is not the preset minimum fan speed; and controlling the fan rotating speed to decrease in a case that the last adjustment action is not to increase the fan rotating speed.

[0049] In the case that the harvester is in the high loss state, the processor can adjust the execution parameters of the components of the harvester to reduce the loss rate of the harvester. The execution parameters of the components of the harvester can include the fan speed of the harvester, etc. Specifically, the processor can obtain the fan speed of the harvester. In the case that the fan speed is not the preset minimum fan speed, the processor can obtain the last adjustment action of the fan of the harvester. The last adjustment action of the fan can mean increasing or decreasing the fan speed. In the case that the last adjustment action is not increasing the fan speed, the processor can control the fan speed of the harvester to decrease.

[0050] In one embodiment, the control method further comprises: in the case that the last adjustment action is increasing the fan speed, obtaining the screen opening degree of the tail screen of the harvester; and in the case that the screen opening degree of the tail screen is not the preset maximum opening degree, controlling the screen opening degree of the tail screen to increase.

[0051] In one embodiment, the control method further comprises: in the case that the screen opening degree of the tail screen is the preset maximum opening degree, controlling the left-right opening degree of the upper screen of the harvester to increase.

[0052] In the case that the harvester is in the high loss state, the processor can adjust the execution parameters of the components of the harvester to reduce the loss rate of the harvester. The execution parameters of the components of the harvester can include the fan speed of the harvester, the screen opening degree of the upper screen of the harvester, and the screen opening degree of the tail screen of the harvester. Specifically, the processor can obtain the fan speed of the harvester. In the case that the fan speed is not the preset minimum fan speed, the processor can obtain the last adjustment action of the fan of the harvester. In the case that the last adjustment action is increasing the fan speed, the processor can obtain the screen opening degree of the tail screen of the harvester. The screen opening degree can mean the opening angle of the screen. When the screen opening degree of the tail screen of the harvester reaches the minimum value set by the electro-hydraulic control of the harvester, the screen opening degree of the tail screen reaches the maximum, and at this time the processor can obtain the preset maximum opening degree of the tail screen. After obtaining the screen opening degree of the tail screen of the harvester and the preset maximum opening degree, the processor can compare the screen opening degree of the tail screen with the preset maximum opening degree. In the case that the screen opening degree of the tail screen is not the preset maximum opening degree, the processor can control the screen opening degree of the tail screen to increase.

[0053] After comparing the screen opening degree of the tail screen with the preset maximum opening degree, in the case that the screen opening degree of the tail screen is the preset maximum opening degree, the processor can control the left-right opening degree of the upper screen of the harvester to increase.

[0054] In one embodiment, the adjusting the execution parameters of the components of the harvester to reduce the impurity rate of the harvester comprises: obtaining a fan rotating speed of the harvester; obtaining a screen opening degree of an upper screen of the harvester in a case that the fan rotating speed is a preset maximum fan speed; controlling the screen opening degree of a tail screen of the harvester to decrease in a case that the screen opening degree of the upper screen is a preset minimum opening degree.

[0055] In one embodiment, the control method further comprises: controlling the left-right opening degree of the upper screen to decrease in a case that the screen opening degree of the upper screen is not the preset minimum opening degree.

[0056] In a case that it is determined that the harvester is not in the high loss state, the processor can determine whether the harvester is in a high impurity state at this time. If the impurity rate of the harvester at this time is higher than a second preset threshold, the processor can determine that the harvester is in the high impurity state. In a case that the harvester is in the high impurity state, the processor can adjust the component parameters of the harvester. For example, the fan rotating speed of the harvester, the screen opening degree of the upper screen of the harvester, and the screen opening degree of the tail screen of the harvester can be adjusted. Specifically, the processor can obtain the fan rotating speed of the harvester. In a case that the fan rotating speed is a preset maximum fan speed, the processor can obtain the screen opening degree of the upper screen of the harvester. The preset maximum fan speed can refer to that the fan rotating speed of the harvester reaches the maximum value set by the electro-hydraulic control. The screen opening degree can refer to the opening angle of the screen. The screen opening degree of the upper screen can refer to the left-right opening degree of the upper screen. When the screen opening degree of the upper screen of the harvester reaches the minimum value set by the electro-hydraulic control of the harvester, the screen opening degree of the upper screen can reach the minimum, and at this time, the processor can obtain the preset minimum opening degree of the upper screen. After obtaining the screen opening degree of the upper screen of the harvester and the preset minimum opening degree, the processor can compare the screen opening degree of the upper screen with the preset minimum opening degree. In a case that the screen opening degree of the upper screen is the preset minimum opening degree, the processor can control the screen opening degree of the tail screen of the harvester to decrease, i.e., to decrease the opening angle of the tail screen.

[0057] After comparing the screen opening degree of the upper screen with the preset minimum opening degree, in a case that the screen opening degree of the upper screen is not the preset minimum opening degree, the processor can control the left-right opening degree of the upper screen to decrease.

[0058] In one embodiment, the control method further comprises: obtaining a last adjustment action for the fan in a case that the fan rotating speed is not the preset maximum fan speed; controlling the fan rotating speed to increase in a case that the last adjustment action is not to decrease the fan rotating speed.

[0059] In a case where it is determined that the harvester is not in the high loss state, the processor can determine whether the harvester is in a high impurity state at this time. If the impurity rate of the harvester at this time is higher than a second preset threshold, the processor can determine that the harvester is in the high impurity state. In a case where the harvester is in the high impurity state, the processor can adjust the component parameters of the harvester. For example, the fan speed of the harvester, the screen opening degree of the upper screen of the harvester, and the screen opening degree of the tail screen of the harvester can be adjusted. Specifically, the processor can obtain the fan speed of the harvester. In a case where the fan speed is not a preset maximum fan speed, the processor can obtain the last adjustment action for the fan. The last adjustment action for the fan can mean that the speed of the fan is increased or decreased. Then the processor can determine whether the last adjustment action is to decrease the speed of the fan. If the last adjustment action is not to decrease the speed of the fan, the processor can control the fan speed of the harvester to increase.

[0060] In an embodiment, the control method further comprises: in a case where the last adjustment action is to decrease the speed of the fan, obtaining the screen opening degree of the upper screen of the harvester; and in a case where the screen opening degree of the upper screen is a preset minimum opening degree, controlling the screen opening degree of the tail screen of the harvester to decrease.

[0061] In an embodiment, the control method further comprises: in a case where the screen opening degree of the upper screen is not the preset minimum opening degree, controlling the left and right opening degrees of the upper screen to decrease.

[0062] In a case where it is determined that the harvester is not in the high loss state, the processor can determine whether the harvester is in a high impurity state at this time. If the impurity rate of the harvester at this time is higher than a second preset threshold, the processor can determine that the harvester is in the high impurity state. In a case where the harvester is in the high impurity state, the processor can adjust the component parameters of the harvester. For example, the fan speed of the harvester, the screen opening degree of the upper screen of the harvester, and the screen opening degree of the tail screen of the harvester can be adjusted. Specifically, the processor can obtain the fan speed of the harvester. In a case where the fan speed is not a preset maximum fan speed, the processor can obtain the last adjustment action for the fan. The last adjustment action for the fan can mean that the speed of the fan is increased or decreased. Then the processor can determine whether the last adjustment action is to decrease the speed of the fan. If the last adjustment action is to decrease the speed of the fan, the processor can obtain the screen opening degree of the upper screen of the harvester. When the screen opening degree of the upper screen of the harvester reaches the minimum value set by the electro-hydraulic control of the harvester, the screen opening degree of the upper screen can reach the minimum, and at this time, the processor can obtain the preset minimum opening degree of the upper screen. Then, the processor can compare the screen opening degree of the upper screen with the preset minimum opening degree. In a case where the screen opening degree of the upper screen is the preset minimum opening degree, the processor can control the screen opening degree of the tail screen of the harvester to decrease.

[0063] After comparing the screen opening degree of the upper screen sheet with the preset minimum opening degree, if the screen opening degree of the upper screen sheet is not the preset minimum opening degree, the processor can control the left and right opening degrees of the upper screen sheet to decrease.

[0064] In one embodiment, the control method further comprises: when adjusting the execution parameter of the component of the harvester, the adjustment amplitude is determined according to the difference between the loss rate and the first preset threshold value, and / or according to the difference between the impurity rate and the second preset threshold value, wherein the greater the difference, the greater the adjustment amplitude.

[0065] When adjusting the execution parameter of the component of the harvester, the adjustment amplitude can be determined according to the difference between the loss rate and the first preset threshold value. The adjustment amplitude can be determined according to the difference between the impurity rate and the second preset threshold value. The greater the difference between the loss rate and the first preset threshold value and / or the difference between the impurity rate and the second preset threshold value, the greater the adjustment amplitude when adjusting the execution parameter of the component of the harvester.

[0066] In one embodiment, after obtaining the loss rate and the impurity rate of the harvester, the processor can continuously obtain the state of the harvester.

[0067] In one embodiment, when it is determined that the loss rate of the harvester is not higher than the first preset threshold value and / or the impurity rate is not higher than the second preset threshold value, the processor can determine that the harvester is in a low-loss low-impurity state. When the harvester is in a low-loss low-impurity state, the processor can not adjust the execution parameter of the component of the harvester.

[0068] In one embodiment, when it is determined that the harvester is not in a high-loss state, the processor can determine whether the state of the harvester at this time is a high-impurity state. If the impurity rate of the harvester at this time is not higher than the second preset threshold value, the processor can determine that the harvester is not in a high-impurity state. At this time, the processor can not adjust the execution parameter of the component of the harvester.

[0069] In one embodiment, as shown in Figure 2 A control method for a harvester is also provided. The processor can obtain the loss rate and the impurity rate of the harvester. Then it can be determined whether the state of the harvester is a low-loss low-impurity state. If the harvester is in a low-loss low-impurity state, the harvester can be in a wheel empty state, i.e. the processor can not adjust the execution parameter of the component of the harvester. If the harvester is not in a low-loss low-impurity state, it is determined whether the harvester is in a high-loss state.

[0070] If it is judged that the harvester is in the high-loss state, it is further judged whether the fan speed of the harvester reaches the minimum, i.e. whether the fan speed of the harvester reaches the minimum value set by the electro-hydraulic control. If the fan speed of the harvester reaches the minimum, it is further judged whether the screen opening of the tail screen reaches the maximum opening. In the high-loss state, if the screen opening of the tail screen reaches the maximum opening, the screen opening of the upper screen can be increased. In the high-loss state, if the screen opening of the tail screen does not reach the maximum opening, the screen opening of the tail screen can be increased. The maximum opening of the tail screen can refer to the screen opening when the screen opening of the tail screen of the harvester reaches the minimum value set by the electro-hydraulic control of the harvester.

[0071] If it is judged that the harvester is in the high-loss state, it is further judged whether the fan speed of the harvester reaches the minimum. If the fan speed of the harvester does not reach the minimum, it is further judged whether the last adjustment action of the fan is to increase the fan speed. If the last adjustment action is not to increase the fan speed, the fan speed of the harvester can be decreased in the high-loss state. If the last adjustment action is to increase the fan speed, it is further judged whether the screen opening of the tail screen reaches the maximum. In the high-loss state, if the screen opening of the tail screen reaches the maximum opening, the screen opening of the upper screen can be increased. In the high-loss state, if the screen opening of the tail screen does not reach the maximum opening, the screen opening of the tail screen can be increased.

[0072] If it is judged that the harvester is not in the high-loss state, it is further judged whether the harvester is in the high-impurity state. If the harvester is not in the high-impurity state, the harvester can be in the idle state, i.e. the processor can not adjust the execution parameters of the components of the harvester. If the harvester is in the high-impurity state, it is further judged whether the fan speed of the harvester reaches the maximum, i.e. whether the fan speed of the harvester reaches the maximum value set by the electro-hydraulic control. If the fan speed reaches the maximum, it is further judged whether the screen opening of the upper screen reaches the minimum opening. In the high-impurity state, if the screen opening of the upper screen reaches the minimum opening, the screen opening of the tail screen can be decreased. In the high-impurity state, if the screen opening of the upper screen does not reach the minimum opening, the screen opening of the upper screen can be decreased. The minimum opening of the upper screen can refer to the screen opening when the screen opening of the upper screen of the harvester reaches the minimum value set by the electro-hydraulic control of the harvester.

[0073] If the harvester is in a high-impurity state, the processor can further determine whether the harvester's fan speed has reached its maximum, i.e., whether the fan speed has reached the maximum value set by the electro-hydraulic control. If the fan speed has not reached its maximum, the processor can further determine whether the last adjustment action of the fan was to reduce the fan speed. If the fan speed was not reduced last time, the processor can increase the fan speed in the high-impurity state. If the fan speed was reduced last time, the processor can further determine whether the opening of the upper screen has reached its minimum. If the upper screen opening is at its minimum, the processor can reduce the opening of the tail screen in the high-impurity state. If the upper screen opening is not at its minimum, the processor can reduce the opening of the upper screen in the high-impurity state.

[0074] The above technical solution prioritizes reducing the harvester's loss rate, achieving comprehensive control over both loss rate and impurity content. This significantly reduces the loss rate and impurity content during crop harvesting, thereby increasing both yield and quality. Furthermore, by adjusting the execution parameters of the harvester's components, errors caused by human intervention or other environmental factors can be avoided, enabling accurate control of the harvester's loss rate and impurity content.
