[0062] my country's agricultural equipment modernization has achieved remarkable results and is entering a new era of innovation and breakthroughs. The vast grain planting area provides an important opportunity for the development of agricultural automation and intelligence. At present, the operation of harvesters in my country relies on the driver's subjective judgment of the grain status and manually controls the concave plate, screen and other working devices to complete the harvesting operation. However, the current harvester operation is too dependent on the driver's subjective judgment, the operation process is cumbersome, and it mainly relies on experience and training to achieve regulation, resulting in a low level of automation and intelligence. This situation not only significantly reduces the operating efficiency of the harvester, but also restricts the further development of the combine harvester.
[0063] Based on this, the embodiment of the present application provides a method, device, harvester and storage medium for adjusting a harvester, which simplifies the setting and control process of the concave plate gap, upper screen opening, lower screen opening and tail screen opening through an integrated operation interface and automatic adjustment system, significantly reduces the difficulty of operation and improves the operation efficiency. At the same time, by using advanced closed-loop control mathematical models and fuzzy PID control strategies, accurate adjustment of these parameters is achieved to meet the needs of different crops, further improving the control accuracy and operation performance.
[0064] To facilitate the understanding of the present application, the technical solution provided by the present application is described in detail below in conjunction with specific embodiments.
[0065] See also Figure 1 , Figure 1 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 the target device of the 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, a binocular camera is 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 camera.
[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 collects image data of the target device and transmits it to the core computing unit. The unit uses the built-in preset opening and closing degree algorithm to process the image data, thereby accurately calculating the actual opening and closing degree of the target device and transmitting the data to the vehicle control unit and the intelligent display terminal.
[0072] See also Figure 2 , Figure 2 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 a 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 The second flowchart of the adjustment device of 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 the specific implementation:
[0078] First, the adjustment instruction of 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 confirm whether it is a one-touch operation instruction; wherein the one-touch operation button is integrated in the intelligent display terminal, and when the user needs to adjust the concave plate gap, the upper screen opening, the lower screen opening and the tail screen opening, he only needs to press the button, and the system can 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 manually adjust the concave plate gap, the upper screen opening, the lower screen opening and the tail screen opening position accurately through the multi-function handle and the bus panel.
[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 respectively.
[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 a target device opening degree reduction instruction, 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 a target device opening degree increase instruction, the motor corresponding to the target device is adjusted to reverse 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 the 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 respectively connected to the motor of the target device and the on-board control unit through hard wires, 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 and closing degree of the target device and the 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 and closing degree of the target device output by the camera into an actual position through a preset second mapping table and displays the actual position through 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 embodiment of the present application, the preset target position is determined by the following two methods:
[0092] In the first method, the user pre-sets the motor position on the intelligent display terminal according to the type of crop to be harvested, and saves these setting values to the on-board control unit.
[0093] The second method is to manually adjust the concave plate, upper screen, lower screen and tail screen to the desired positions, and then click Save on the intelligent display terminal to save these manually adjusted positions to the on-board control unit.
[0094] See also Figure 4 , Figure 4 This is a third flow chart of an adjustment device for a harvester provided in an embodiment of the present application.
[0095] Step S105: adjusting the motor corresponding to the target device to the target position based on the deviation and a preset first mapping table.
[0096] like Figure 4 As shown in , regarding step S105, the specific implementation includes the following steps:
[0097] First, based on the deviation, a deviation change rate between the current position and the target position is determined.
[0098] Then, based on the deviation, the deviation change rate and a preset first mapping table, a PID fuzzy coefficient is determined, wherein the PID fuzzy coefficient includes at least one of the following items: a proportional coefficient, an integral coefficient, and a differential coefficient.
[0099] Here, determining the PID fuzzy coefficient based on the deviation, the deviation change rate and the preset first mapping table includes the following steps in specific implementation:
[0100] First, after the vehicle-mounted control unit calculates the deviation and the deviation change rate, it determines whether the deviation and the deviation change rate exceed the set limit value.
[0101] Secondly, if the deviation and the deviation change rate exceed the corresponding set limit values respectively, the deviation and the deviation change rate are set to the corresponding set limit values and fuzzy processed; if the deviation and the deviation change rate do not exceed the corresponding set limit values respectively, the deviation and the deviation change rate are fuzzy processed.
[0102] Then, the proportional coefficient, the integral coefficient and the 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 reduce the deviation rapidly. However, if the proportional coefficient is too large, the deviation change rate will increase. At this time, a smaller differential coefficient needs to be selected to suppress the increase in the deviation change rate. 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. 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 the 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 embodiment of the present application provides a method for adjusting a harvester, through which the setting and control process of the concave plate gap, the upper screen opening, the lower screen opening and the tail screen opening are simplified, the operation difficulty is significantly reduced and the operation efficiency is improved. At the same time, by using advanced closed-loop control mathematical models and fuzzy PID control strategies, accurate adjustment of these parameters is achieved to adapt to the needs of different crops, and the control accuracy and operation performance are further improved.
