[0062] my country has achieved remarkable results in modernizing its agricultural equipment and is entering a new era of innovation and breakthroughs. The vast area of ​​grain cultivation provides a significant opportunity for the development of agricultural automation and intelligent systems. Currently, harvester operation in my country relies on the driver's subjective judgment of grain conditions, manually controlling working devices such as the concave plate and screen to complete the harvesting operation. However, current harvester operation is overly dependent on the driver's subjective judgment, the operation process is cumbersome, and control relies primarily on experience and training, resulting in a low level of automation and intelligent systems. This situation not only significantly reduces harvester efficiency but also poses a constraint on the further development of combine harvesters.

[0063] Based on this, the embodiments of the present application provide a harvester adjustment method, device, harvester, and storage medium. Through an integrated user interface and automatic adjustment system, the setting and control process of the concave plate gap, upper screen opening, lower screen opening, and tail screen opening are simplified, significantly reducing operational difficulty and improving operational efficiency. Furthermore, by utilizing advanced closed-loop control mathematical models and fuzzy PID control strategies, these parameters can be precisely adjusted to suit the needs of different crops, further improving control accuracy and operational performance.

[0064] To facilitate understanding of the present application, the technical solutions provided in the present application are described in detail below in conjunction with specific embodiments.

[0065] See also Figure 1 , Figure 1 This is one of the flow charts of a harvester adjustment method provided in an embodiment of the present application.

[0066] like Figure 1 As shown in , the adjustment method includes:

[0067] Step S101: collecting image data of a target device of a harvester.

[0068] In an embodiment of the present application, the target equipment includes at least one of the following items: a concave plate, an upper screen, a lower screen, and a tail screen.

[0069] Specifically, binocular cameras are installed on the front side wall of the concave plate and the side wall of the screen box, and image information of the target device is collected through the binocular cameras.

[0070] Step S102: determining the opening and closing degree of the target device according to the image data.

[0071] In the embodiment of the present application, the binocular camera captures image data of the target device and transmits it to the core computing unit. This unit processes the image data using a built-in preset degree of opening and closing algorithm to accurately calculate the actual degree of opening and closing of the target device and transmits the data to the vehicle control unit and intelligent display terminal.

[0072] See also Figure 2 , Figure 2 This is a structural block diagram of an adjustment device for a harvester provided in an embodiment of the present application.

[0073] like Figure 2 As shown in , the binocular camera is connected to the core computing unit through a feeder, the core computing unit is connected to the vehicle control unit through a CAN bus, and the data is efficiently transmitted to the vehicle control unit through the CAN bus.

[0074] Step S103: determining a current position of the motor corresponding to the target device based on the opening and closing degree.

[0075] In the embodiment of the present application, the opening and closing degree of the target equipment includes: concave plate gap, upper screen opening, lower screen opening and tail screen opening.

[0076] See also Figure 3 , Figure 3 This is the second flow chart of an adjustment device for a harvester provided in an embodiment of the present application.

[0077] like Figure 3 As shown in , regarding step S103, the following steps are also included before specific implementation:

[0078] First, an adjustment instruction for the target device is obtained to determine whether the adjustment instruction is a one-touch operation instruction. In the embodiment of the present application, the vehicle-mounted control unit receives the adjustment instruction and identifies it to determine whether it is a one-touch operation instruction. The one-touch operation button is integrated into the intelligent display terminal. When the user needs to adjust the concave plate gap, upper screen opening, lower screen opening, and tail screen opening, he only needs to press the button, and the system will automatically perform the corresponding position adjustment operation.

[0079] Then, based on the adjustment instruction, it is determined whether the adjustment instruction is a one-touch operation instruction. When the adjustment instruction is a one-touch operation instruction, based on the current position and a preset target position, a deviation between the current position and the target position is determined.

[0080] When the adjustment instruction is not a one-touch operation instruction, it is determined whether the adjustment instruction is an instruction to increase the opening and closing degree of the target device. In the embodiment of the present application, the instruction to increase the opening and closing degree is a manual operation instruction, and the user can use the multi-function handle and bus panel to accurately manually adjust the concave plate gap, upper screen opening, lower screen opening, and tail screen opening position.

[0081] like Figure 2 As shown in , the multi-function handle is connected to the bus panel and the on-board control unit through buses.

[0082] When the adjustment instruction is an instruction to increase the opening and closing degree of the target device, the motor corresponding to the target device is adjusted to the target position. In an embodiment of the present application, when the adjustment instruction is an instruction to increase the opening and closing degree of the target device, the motor corresponding to the target device is adjusted to rotate forward to the target increase position.

[0083] When the adjustment instruction is not an instruction to increase the opening and closing degree of the target device, it is determined whether the adjustment instruction is an instruction to decrease the opening and closing degree of the target device. In the embodiment of the present application, the instruction to decrease the opening and closing degree is a manual operation instruction.

[0084] When the adjustment instruction is an instruction to reduce the opening and closing degree of the target device, the motor corresponding to the target device is adjusted to the target position. In the embodiment of the present application, when the adjustment instruction is an instruction to increase the opening and closing degree of the target device, the motor corresponding to the target device is reversed to the target reduction position.

[0085] When the adjustment instruction is not an instruction to reduce the opening and closing degree of the target device, the adjustment of the motor corresponding to the target device is stopped.

[0086] Regarding step S103, the specific implementation includes the following steps:

[0087] First, obtain the voltage data corresponding to the current position of the motor. In an embodiment of the present application, a position sensor is integrated inside the motor to obtain the voltage data corresponding to the current position of the motor. As an example, the present application uses a potentiometer sensor, which obtains the voltage data corresponding to the current position of the motor and transmits the real-time voltage signal to the vehicle control unit. Specifically, the power supply of the potentiometer sensor is supplied by the 5V DC power provided by the vehicle control unit, ensuring stable and reliable operation of the sensor. At the same time, the voltage signal range output by the potentiometer sensor is set to 0.5V to 4.5V.

[0088] like Figure 2 As shown in , the on-board control unit is connected to the motor of the target device through a hard wire, and the motor position sensor is connected to the motor of the target device and the on-board control unit through hard wires, respectively, wherein the motor of the target device includes: a concave plate gap adjustment motor, an upper screen opening adjustment motor, a lower screen opening adjustment motor and a tail screen opening adjustment motor.

[0089] Then, based on the voltage data, the opening / closing degree of the target device, and a preset first mapping table, the current position of the motor corresponding to the target device is determined and the current position is displayed. In an embodiment of the present application, the vehicle control unit converts the voltage data and the opening / closing degree of the target device output by the camera into an actual position using a preset second mapping table, and displays the actual position on the intelligent display terminal.

[0090] Step S104, determining a deviation between the current position and the target position based on the current position and the preset target position.

[0091] In the embodiments of the present application, the preset target position is determined in the following two ways:

[0092] Firstly, the user sets the motor position on the intelligent display terminal according to the type of the harvested crops, and saves these setting values into the vehicle control unit.

[0093] Secondly, the user manually adjusts the concave plate, upper sieve, lower sieve and tail sieve to the desired position, and then clicks save on the intelligent display terminal to save these manually adjusted positions into the vehicle control unit.

[0094] Please refer to Figure 4 , Figure 4 for the flowchart of the adjusting device of the harvester provided in the embodiments of the present application.

[0095] Step S105, adjusting the motor corresponding to the target device to the target position based on the deviation and the preset first mapping table.

[0096] As shown in Figure 4 , regarding step S105, in the specific implementation, the following steps are included:

[0097] Firstly, determining a deviation change rate of the deviation between the current position and the target position based on the deviation.

[0098] Then, determining a PID fuzzy coefficient based on the deviation, the deviation change rate and the preset first mapping table, wherein the PID fuzzy coefficient includes at least one of the following: a proportional coefficient, an integral coefficient and a differential coefficient.

[0099] Here, regarding determining the PID fuzzy coefficient based on the deviation, the deviation change rate and the preset first mapping table, in the specific implementation, the following steps are included:

[0100] Firstly, when the vehicle control unit calculates the deviation and the deviation change rate, it is determined whether the deviation and the deviation change rate exceed the set limit value.

[0101] Secondly, if the deviation and the deviation change rate respectively exceed the corresponding set limit value, the deviation and the deviation change rate are set to the corresponding set limit value and are subjected to fuzzy processing; if the deviation and the deviation change rate do not respectively exceed the corresponding set limit value, the deviation and the deviation change rate are subjected to fuzzy processing.

[0102] Then, the proportional coefficient, integral coefficient and differential coefficient are calculated by looking up the first mapping table, and the adjustment amount required for adjusting the target motor is calculated by linearly combining the calculated proportional coefficient, integral coefficient and differential coefficient.

[0103] Next, it is determined whether the adjustment amount exceeds a set adjustment amount limit value.

[0104] Finally, if the adjustment amount exceeds the set limit value, the adjustment amount is set to the set adjustment amount limit value. If the adjustment amount does not exceed the set limit value, the current position of the motor is adjusted to the target position according to the adjustment amount.

[0105] In the embodiment of the present application, the vehicle control unit continuously obtains the deviation and the rate of change of the deviation, and the fuzzy PID control uses the deviation and the rate of change of the deviation as the input of the fuzzy PID controller. Based on the fuzzy control rules established by the fuzzy PID controller, the system can dynamically generate the corresponding fuzzy PID coefficients. The vehicle control unit formulates the first mapping table through the following four fuzzy control rules:

[0106] The first fuzzy control rule is that when the deviation between the target position of the motor and the current position of the motor is greater than the set deviation range, a larger proportional coefficient is selected to quickly reduce the deviation. However, if the proportional coefficient is too large, the rate of change of the deviation will increase. At this time, a smaller differential coefficient needs to be selected to suppress the increase in the rate of change of the deviation. In order to avoid overshoot, a smaller integral coefficient is required.

[0107] The second fuzzy control rule is that when the deviation between the target position of the motor and the current position of the motor is less than the set deviation range, in order to improve stability and reduce steady-state error, a larger proportional coefficient and integral coefficient are selected. For the differential coefficient, if the deviation is greater than the middle value of the set range, a smaller differential coefficient is selected. If the deviation is less than or equal to the middle value of the set range, a larger differential coefficient is selected.

[0108] The third fuzzy control rule is that when the deviation between the target position of the motor and the current position of the motor is within the set deviation range and the deviation change rate is within the set deviation change rate range, a smaller proportional coefficient and integral coefficient are selected. In order to avoid overshoot, a moderate differential coefficient is selected to improve the system response speed.

[0109] The fourth fuzzy control rule selects a smaller proportional coefficient and a larger differential coefficient when the deviation change rate is greater than the set deviation change rate range.

[0110] See again Figure 4 ,like Figure 4 As shown in , finally, the motor corresponding to the target device is adjusted to the target position according to the PID fuzzy coefficient.

[0111] In an embodiment of the present application, after the motor corresponding to the target device is adjusted to the target position, the motor position sensor sends real-time position information to the on-board control unit, and the on-board control unit displays the real-time position on a display screen.

[0112] The present invention provides a harvester adjustment method that simplifies the setting and control of the concave plate gap, upper screen opening, lower screen opening, and tail screen opening, significantly reducing operational difficulty and improving operational efficiency. Furthermore, by utilizing advanced closed-loop control mathematical models and fuzzy PID control strategies, these parameters can be precisely adjusted to meet the needs of different crops, further improving control accuracy and operational performance.

[0113] Based on the same application concept, the embodiment of the present application also provides a harvester adjustment device corresponding to the harvester adjustment method provided in the above embodiment. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the harvester adjustment method in the above embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0126] The acquisition module 516 acquires an adjustment instruction of the target device, wherein the target device includes at least one of the following items: a concave plate, an upper screen, a lower screen, and a tail screen.

[0127] The one-touch determination module 517 determines whether the adjustment instruction is a one-touch operation instruction based on the adjustment instruction.

[0128] The increase determination module 518 determines whether the adjustment instruction is an instruction to increase the opening and closing degree of the target device when the adjustment instruction is not a one-touch operation instruction.

[0129] The increasing adjustment module 519 adjusts the motor corresponding to the target device to a target increasing position when the adjustment instruction is an instruction to increase the opening and closing degree of the target device.

[0130] The decrease determination module 520 determines whether the adjustment instruction is a target device opening / closing degree decrease instruction when the adjustment instruction is not a target device opening / closing degree increase instruction.

[0131] The reduction adjustment module 521 adjusts the motor corresponding to the target device to a target reduction position when the adjustment instruction is an instruction to reduce the opening and closing degree of the target device.

[0132] Preferably, the adjustment module 515 is specifically configured to:

[0133] First, based on the deviation, a rate of change of the deviation between the current position and the target position is determined.

[0134] Then, based on the deviation, the deviation change rate and a preset second mapping table, a PID fuzzy coefficient for adjusting the opening and closing degree of the target device is determined.

[0135] Finally, the motor corresponding to the target device is adjusted to the target position according to the PID fuzzy coefficient.

[0136] The energy management method for hybrid vehicles provided in the embodiments of this application simplifies the setting and control process of the concave plate gap, upper screen opening, lower screen opening, and tail screen opening, significantly reducing operational difficulty and improving operational efficiency.
