Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery control, and in particular to a control method and storage medium for agricultural machinery. Background Art

[0002] Combine harvesters are important agricultural machinery in modern agriculture. They are used to complete agricultural operations such as cutting, threshing, separating and cleaning grains or crops. They can significantly improve agricultural production efficiency and reduce farmers' labor intensity.

[0003] The function of the battery in the combine harvester is to power electrical equipment (for example, work lights, displays, terminal GPS, etc.) and provide current for the engine to start. The battery power will directly affect whether the combine harvester can operate normally. The inventors of the present application found in the process of realizing the present invention that the current method of avoiding battery power failure usually relies on manual control: after the use of the combine harvester is finished, the driver needs to manually turn off each electrical device; when the combine harvester is not used for a long time, the driver needs to manually disconnect the battery power supply circuit (for example, disconnect the battery main switch or remove the battery negative line). This control method has certain uncertainties (for example, the driver forgets to turn off the electrical equipment / disconnect the battery power supply circuit), so the risk of battery power failure still exists, resulting in low efficiency of battery power failure prevention control.

[0045] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0046] One aspect of an embodiment of the present invention provides a control method for an agricultural machine, the agricultural machine comprising a power storage element, a seat structure and an alarm device. Figure 1 As shown, Figure 1 : is a flow chart of a control method for agricultural machinery provided by an embodiment of the present invention, and the specific flow chart may be as follows:

[0047] S101. Acquire current voltage data of the storage element and current pressure data of the seat structure.

[0048] The current voltage data is the voltage value of the storage element in the current period; the current pressure data is the pressure value of the seat structure in the current period. Optionally, in an embodiment of the present invention, the storage element is a battery, and the seat structure is a seat in the cab of a combine harvester.

[0049] The function of the battery in agricultural machinery (for example, a combine harvester) is to power electrical equipment (for example, work lights, displays, terminal GPS, etc.) and provide current for the engine to start. The battery charge will directly affect whether the combine harvester can operate normally. In an embodiment of the present invention, the current voltage data of the storage element and the current pressure data of the seat structure are obtained so that the battery can be processed accordingly according to the current voltage data and the current pressure data, thereby avoiding the situation where the combine harvester cannot operate normally due to battery depletion.

[0050] S102. Based on the current voltage data and the current pressure data, determine the current storage state of the storage element and the current occupant state of the seat structure.

[0051] Among them, the current power storage state represents the current power status of the power storage element; the current occupant state represents whether there is a occupant on the current seat structure.

[0052] In order to ensure the battery's anti-low-power control effect without affecting the user's normal use of the combine harvester, it is necessary to determine the current power status of the battery and whether there are people in the current combine harvester, so as to take targeted anti-low-power measures according to the actual situation later. To this end, in an embodiment of the present invention, the current storage state of the storage element is determined according to the current voltage data to determine the current power status of the battery. In addition, it is determined according to the current pressure data whether there is sufficient pressure applied to the seat structure, thereby determining the current personnel status of the seat structure, and then determining whether there are people in the combine harvester.

[0053] S103. When the current power storage state and the current personnel state satisfy the power shortage prevention control conditions, the alarm device is controlled to alarm, and / or the charging and discharging of the power storage element is controlled according to a preset power shortage prevention control mode.

[0054] Among them, the power-loss prevention control condition is the basis for judging whether it is necessary to take power-loss prevention control measures for the alarm device / battery.

[0055] Specifically, in an embodiment of the present invention, when the current power storage state and the current personnel state meet the anti-low power control conditions, it means that the current battery power is insufficient, and it is necessary for the controller to perform alarm control on the alarm device so that the alarm device sends a corresponding alarm signal, thereby reminding the user in the vehicle to immediately stop using the battery (or start the engine to charge the battery), and / or determine the corresponding preset anti-low power control mode according to the actual current power storage state and the current personnel state, and control the charging and discharging of the battery according to the preset anti-low power control mode to avoid low power.

[0056] Furthermore, if Figure 2 As shown, Figure 2 FIG. 1 is another flow chart of a control method for agricultural machinery provided by an embodiment of the present invention. The specific flow chart may be as follows:

[0057] S201. Obtain preset voltage data and preset pressure data.

[0058] Specifically, in an embodiment of the present invention, voltage monitoring processing is performed on the battery element to obtain the engine starting critical voltage value corresponding to the battery element (if the voltage in the battery is less than the engine starting critical voltage value, the engine of the combine harvester cannot be started, and if the voltage in the battery is greater than the engine starting critical voltage value, the engine of the combine harvester can be started normally), and the preset voltage data is determined according to the engine starting critical voltage value; and, pressure monitoring processing is performed on the seat structure to obtain the human body seating critical pressure value corresponding to the seat structure (used to determine whether someone is sitting on the seat structure), and the preset pressure data is determined according to the human body seating critical pressure value.

[0059] Optionally, the voltage monitoring process includes: using a battery to power electrical equipment to consume the battery power, and testing whether the engine can start normally whenever the battery voltage value drops to a preset value (for example, 0.1V). If the engine cannot start, the battery voltage value at this time is recorded. After repeating the above process multiple times, the average of the voltage values ​​obtained multiple times is used as the engine starting critical voltage value; and, charging the battery and recording the battery voltage value when it is fully charged, and the voltage value is used as the preset nominal voltage data β.

[0060] In the embodiment of the present invention, the preset voltage data includes the preset nominal voltage data β, the first preset voltage data and the second preset voltage data, wherein the first preset voltage data is the product of the engine start critical voltage value α and the first correction coefficient K1 (i.e., the first preset voltage data = α × K1), the second preset voltage data is the product of the engine start critical voltage value and the second correction coefficient K2 (i.e., the second preset voltage data = α × K2), and the first preset voltage data is greater than the second preset voltage data. Optionally, K1 = 1.08, K2 = 1.02, and in actual application, the values ​​of K1 and K2 can also be slightly adjusted according to actual needs.

[0061] Furthermore, the pressure monitoring process includes: when an adult sits on the seat, recording the pressure value applied by the adult to the seat, and after repeating the above process multiple times (which can be completed by different adults respectively), taking the average of the pressure values ​​obtained multiple times as the critical pressure value for human body sitting. In the embodiment of the present invention, the preset pressure data is the product of the critical pressure value P for human body sitting and the third correction coefficient K3 (i.e., the preset pressure data = P × K3). Optionally, K3 = 0.5, and the value of K3 can also be slightly adjusted according to actual needs during actual application.

[0062] S202. Acquire current voltage data of the storage element and current pressure data of the seat structure.

[0063] Specifically, in the embodiment of the present invention, Figure 3 As shown, a voltage acquisition device 304 (e.g., an oscilloscope) is pre-connected to both ends of the battery 303, and the seat is connected to a pressure acquisition device 305 (e.g., a pressure sensor), so that the current voltage data of the battery 303 and the current pressure data of the seat are respectively acquired through the voltage acquisition device 304 and the pressure acquisition device 305, and the voltage acquisition device 304 and the pressure acquisition device 305 respectively send the current voltage data and the current pressure data to the first control unit 301 and the second control unit 302 in the controller.

[0064] S203. Compare the current voltage data with the preset voltage data to determine the current storage state of the storage element, and compare the current pressure data with the preset pressure data to determine the current occupant state of the seat structure.

[0065] Specifically, the current voltage data is compared with the preset voltage data to determine the current charge status of the battery, thereby determining the current storage state of the storage element. In addition, the current pressure data is compared with the preset pressure data to determine whether sufficient pressure is currently applied to the seat structure, thereby determining the current occupant status of the seat structure.

[0066] Optionally, in an embodiment of the present invention, when the current voltage data is less than the preset nominal voltage data β, and greater than or equal to the first preset voltage data α×K1, it indicates that the battery power is continuously decreasing, so the current storage state of the storage element is determined to be a decreasing power state; when the current voltage data is less than or equal to the second preset voltage data α×K2, it indicates that the battery power is insufficient (it is very likely that the engine cannot be started), so the current storage state of the storage element is determined to be a low power state.

[0067] In addition, when the current pressure data is less than the preset pressure data, it means that the pressure currently applied to the seat does not meet the pressure that should be applied to it when an adult sits down, so the current occupant state of the seat structure is determined to be an unoccupied state; when the current pressure data is greater than or equal to the preset pressure data, it means that the pressure currently applied to the seat meets the pressure that should be applied to it when an adult sits down, so the current occupant state of the seat structure is determined to be an occupied state.

[0068] S2041. When the current power storage state is a power reduction state and the current personnel state is an occupied state, determine that the current power storage state and the current personnel state meet the power shortage prevention control conditions, and perform alarm control on the alarm device.

[0069] In an embodiment of the present invention, when the current power storage state is a power reduction state and the current personnel state is an occupied state, it is determined that the current power storage state and the current personnel state meet the power shortage prevention control conditions, and the controller sends an alarm instruction to the alarm device to make the alarm device send a power reduction alarm signal to remind the occupants of the vehicle to immediately stop using the battery, or start the engine to charge the battery.

[0070] For example, Figure 3 As shown, the second control unit 302 sends an alarm instruction to the alarm device 306, so that the alarm device 306 sends a power reduction alarm signal, wherein the alarm device 306 includes a vehicle audio system or a vehicle display screen, and the power reduction alarm signal includes a voice / text message of "The power is decreasing, please stop using electricity".

[0071] S2042. When the current power storage state is too low and the current personnel state is unmanned, determine that the current power storage state and the current personnel state meet the power shortage prevention control conditions, and control the charging and discharging of the power storage element according to the first preset power shortage prevention control mode.

[0072] In the embodiment of the present invention, when the current storage state is a low power state and the current personnel state is an unmanned state, it indicates that the battery is currently at a risk of power failure, so it is determined that the current storage state and the current personnel state meet the power failure prevention control condition, wherein the process of controlling the charge and discharge of the storage element according to the first preset power failure prevention control mode includes: Figure 3As shown, the first control unit 301 controls the relay (not shown in the figure) so that the relay controls the first contactor 308 to disconnect the main power switch 309, and the relay controls the second contactor 311 to close, so as to switch the storage element discharge circuit (i.e., the circuit for supplying power to the electrical device 307 through the battery 303) to the storage element charging circuit (i.e., the circuit for supplying power to the battery 303 through the external energy storage element 310), so that the external energy storage element 310 in the storage element charging circuit charges the battery 303. Optionally, in an embodiment of the present invention, the external energy storage element is a solar charging device, which is composed of a solar panel and a charging power management circuit. When the solar charging device is turned on, the solar panel will charge the battery according to the light intensity.

[0073] S2043. When the current power storage state is too low and the current personnel state is occupied, determine that the current power storage state and the current personnel state meet the power shortage prevention control conditions, and control the charging and discharging of the power storage element according to the second preset power shortage prevention control mode.

[0074] In the embodiment of the present invention, when the current power storage state is a low power state and the current personnel state is a occupied state, it indicates that the battery is currently at a risk of power shortage, so it is determined that the current power storage state and the current personnel state meet the power shortage prevention control condition, wherein the process of controlling the charge and discharge of the storage element according to the second preset power shortage prevention control mode includes: Figure 3 As shown, the second control unit 302 sends an alarm instruction to the alarm device 306, so that the alarm device 306 continuously sends out a low-battery alarm signal. At the same time, the second control unit 302 monitors the duration of the low-battery alarm signal. When the duration of the low-battery alarm signal is equal to the preset duration, the storage element discharge circuit is switched to the storage element charging circuit, so that the external energy storage element 310 in the storage element charging circuit charges the battery 303. The alarm device sends an alarm signal to remind the occupants to complete the current tasks that require the participation of electrical equipment as soon as possible, so as to avoid affecting the progress of the current tasks due to the sudden disconnection of the storage element discharge circuit.

[0075] Specifically, the alarm device 306 includes a vehicle-mounted audio system or a vehicle-mounted display screen. If the alarm device 306 is a vehicle-mounted display screen, the alarm signal is a graphic information displayed on the vehicle-mounted display screen, and the second control unit 302 monitors the display duration of the graphic information. When the display duration is equal to the preset duration, the storage element discharge circuit is switched to the storage element charging circuit; for example, when the preset duration is 10s and the display duration of the graphic information on the vehicle-mounted display screen is 10s, the storage element discharge circuit is switched to the storage element charging circuit.

[0076] If the alarm device 306 is a car audio system, the alarm signal is a voice for prompting the user (for example, "The battery is low, and the main power supply will be switched soon"), and the second control unit 302 monitors the playback duration of the voice, and when the playback duration of the voice is equal to the preset duration, the storage element discharge circuit is switched to the storage element charging circuit. For example, when the preset duration is 10s and the playback duration of the voice emitted by the car audio system is 10s, the storage element discharge circuit is switched to the storage element charging circuit.

[0077] Optionally, when the alarm device 306 is a car audio system, the second control unit 302 may also monitor the number of repetitions of the voice emitted by the car audio system, and when the number of repetitions of the voice system is equal to a preset number, the storage element discharge circuit is switched to the storage element charging circuit. For example, the preset number is 3 times, and when it is detected that the car audio system repeatedly emits the voice "low power, about to switch to the main power supply" 3 times, the storage element discharge circuit is switched to the storage element charging circuit.

[0078] Furthermore, in actual application, the controller can also detect in real time the interval between the current moment and the last time the engine stopped running. If the interval is equal to the time threshold, it means that the combine harvester has not been used for a long time, and the controller will switch the storage element discharge circuit to the storage element charging circuit, thereby avoiding the phenomenon of battery power loss and extending the service life of the battery. For example, if the time threshold is 30 days, and the interval between the current moment and the last time the engine stopped running is 30 days, the controller will directly switch the storage element discharge circuit to the storage element charging circuit.

[0079] In addition, if Figure 3 As shown, after the discharge circuit of the storage element is switched to the charging circuit of the storage element, the controller sends a reminder instruction to the remote device 312, so that the remote device 312 sends a reminder message of "the power supply circuit has been switched" to the application downloaded by the user terminal through the cloud platform, wherein the remote device 312 and the controller communicate through the CAN bus, and the remote device 312 and the controller have low power and low energy consumption, and can be powered by the battery 303. Optionally, in actual application, a small-capacity battery can also be set to power the controller and the remote device 312 separately to ensure that the battery 303 is fully charged.

[0080] Furthermore, after the storage element discharge circuit is switched to the storage element charging circuit to charge the battery through the external energy storage element, the voltage data of the battery and the pressure data of the seat are continuously collected by the voltage acquisition device and the pressure acquisition device, and the storage state of the battery and the occupant state of the seat are determined based on the voltage data and the pressure data. When the storage state is a saturated state (i.e., when the voltage value of the battery is equal to the preset nominal voltage data β) and the occupant state is an occupied state, as Figure 3 As shown, the first control unit 301 controls the relay so that the relay controls the first contactor 308 to close the main power switch 309, and controls the second contactor 311 to open, so as to switch the charging circuit of the storage element to the discharging circuit of the storage element, thereby interrupting the charging of the battery 303 by the external energy storage element 310, and supplying power to the electrical equipment 307 through the battery 303, so as to facilitate the normal use of the various electrical equipment 307 by the people in the vehicle.

[0081] It should be noted that the controller can realize the switching of the power supply circuit in accordance with the above-mentioned indirect control method (i.e., indirectly controlling the contactor by controlling the relay), or directly control the contactor. In the embodiment of the present invention, no specific limitation is made on the control method of switching the power supply circuit.

[0082] The control method for agricultural machinery provided by the present invention can automatically determine the current storage state of the battery element and the current occupant status of the seat structure based on the current voltage data and the current pressure data, and automatically perform alarm control on the alarm device when the current storage state and the current occupant status meet the anti-low-power control conditions, and / or perform charge and discharge control on the battery element according to a preset anti-low-power control mode. The control process does not require human participation, thereby effectively avoiding the risk of battery low power caused by human subjective factors, thereby effectively improving the battery low-power control efficiency.

[0083] In addition, another aspect of the embodiment of the present invention provides a control device for agricultural machinery, wherein the agricultural machinery includes a storage element, a seat structure and an alarm device, see Figure 4 , Figure 4 The control device for agricultural machinery provided by an embodiment of the present invention is specifically described, and the control device includes: a voltage acquisition device 304, a pressure acquisition device 305 and a controller 40, wherein:
