[0040] The beneficial effects of the grain tank cover control method of a combine harvester provided by the present invention are as follows:

[0041] First, by acquiring the voltage signal sent by the grain tank cover angle sensor and the extended or retracted length of the grain drum electric push rod in real time, the real-time status of the combine harvester's grain tank cover can be accurately determined, providing accurate data for subsequent control operations. This prevents misoperation caused by inaccurate information and improves the reliability and safety of harvester operations. Second, the voltage signal is converted into a digital signal and sent to the intelligent display terminal, enabling digital signal processing and remote monitoring. This allows operators to intuitively view the grain tank cover status information on the intelligent display terminal, facilitating timely identification of problems and adjustments, improving operational convenience and efficiency. Furthermore, the grain tank cover is controlled based on the user's open or close instructions given on the intelligent display terminal, combined with the voltage signal and length. This achieves precise automated control of the grain tank cover, reducing manual intervention and operator labor intensity, while improving control accuracy and response speed, contributing to improved combine harvester operating efficiency and quality.

[0042] Furthermore, according to the opening or closing instruction given by the user on the intelligent display terminal, combined with the voltage signal and length, the process of controlling the grain tank cover is specifically as follows:

[0043] When the user gives an opening instruction on the intelligent display terminal, it is determined whether the combine harvester to be controlled meets the first enabling condition and the first triggering condition, and when both are met, the grain tank cover is controlled to be opened in combination with the voltage signal and length.

[0044] Furthermore, according to the opening or closing instruction given by the user on the intelligent display terminal, combined with the voltage signal and length, the process of controlling the grain tank cover is specifically as follows:

[0045] When the user gives a closing instruction on the intelligent display terminal, it is determined whether the combine harvester to be controlled meets the second enabling condition and the second triggering condition, and when both are met, the grain tank cover is controlled to be closed in combination with the voltage signal and length.

[0046] Furthermore, it also includes:

[0047] Acquire adjustment parameters of parameters of working components by the user on the intelligent display terminal, and adjust the corresponding working components according to the adjustment parameters.

[0048] Example 1, as Figure 2 As shown in the figure, the vehicle control unit is a core component in the combine harvester control system, collecting input signals and outputting control signals. The vehicle control unit receives the voltage signal from the grain tank cover angle sensor in real time and converts it into the grain tank cover angle.

[0049] The grain tank cover angle sensor is installed on the grain tank assembly. The angle sensor is a Hall sensor that can obtain the grain tank cover angle during the working process in real time by converting the angle into voltage. The output voltage range is 0 to 5V.

[0050] The electric push rod of the grain lifting drum is installed on the grain elevator assembly, which can obtain and adjust the length of the grain lifting drum in real time.

[0051] The solenoid valve is installed on the valve group to control the flow direction and flow of hydraulic oil, thereby accurately controlling the action of the hydraulic system.

[0052] There are a grain tank cover opening switch and a grain tank cover closing switch on the armrest box. By pressing the switch, the grain tank cover can be controlled to be unfolded and retracted with one button.

[0053] The intelligent display terminal is a parameter display and setting unit that communicates with the control unit via the CAN bus. The parameter setting unit includes a folding function. Users can control the continuous expansion and contraction of the grain tank cover and grain lifting drum by clicking the switches on the interface.

[0065] b. The vehicle control unit controls the grain tank cover opening solenoid valve to be energized and simultaneously sends the grain tank cover opening solenoid valve status to the intelligent display terminal, indicating that the grain tank cover opening solenoid valve has output;

[0066] c. When the vehicle control unit determines the grain tank cover angle is ≥80°, it activates the grain drum push rod and simultaneously receives feedback from the grain drum control unit on its actual position.

[0067] 4) Exit condition ((a|b)&c)

[0068] a. When the angle sensor is normal, the VCU sends the grain tank cover angle ≥99 with a delay of 10s;

[0069] b. When the angle sensor is abnormal, the solenoid valve output is delayed by 25 seconds. 25 seconds is the time it takes for the grain tank cover to be fully opened.

[0070] c. The VCU receives the grain lifting hopper position reaching the set value 270 and delays for 5 seconds;

[0087] b. When the angle sensor is abnormal, the solenoid valve output is delayed by 25s;

[0088] c. The vehicle control unit receives the grain drum position = 0 and delays for 5 seconds;

[0089] When the one-button opening and one-button closing actions of the grain tank cover cannot be performed, the grain tank cover can be continuously opened and closed through the folding interface function of the intelligent display terminal.

[0090] like Figure 3 As shown, 1-menu, 2-secondary interface, 3-grain tank cover folding function area, 4-grain barrel folding function area, 5-grain tank cover folding function start switch, the grain tank cover can be opened and closed only after the switch is turned on, 6-grain tank cover folding function close switch, when the folding function is not in use, click the close switch to lock the function to prevent users from accidentally touching it, 7-function close indication, when the folding function is not turned on, the expansion and closing switches of the grain barrel cannot be clicked, 8-grain tank cover opening switch, keep pressing the grain tank cover opening switch to continuously control the opening of the grain tank cover, 9- Grain tank lid closing switch, continuously pressing the grain tank lid closing switch can continuously control the closing of the grain tank lid, 10-liter grain barrel expansion switch, continuously pressing the grain barrel expansion switch can continuously control the expansion of the grain barrel, 11-liter grain barrel retraction switch, continuously pressing the grain barrel retraction switch can continuously control the retraction of the grain barrel, 12-liter grain barrel folding function start switch, the grain barrel can be expanded and retracted only after the switch is turned on, 13-liter grain barrel folding function turn off switch, when the folding function is not in use, click the turn off switch to lock the function to prevent users from accidentally touching it.
