DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the present application provides a control method for automatic shutdown of a tractor, which can be executed by a device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0026] like Figure 1 As shown, a control method for automatic shutdown of a tractor is shown, with an electronic device as the execution subject, and the main process of the method is described as follows (steps S101 to S104): Step S101: obtaining the current flameout indication information of the tractor.

[0027] The tractor includes a flameout switch and an engine. It is easy to understand that the flameout switch is an important component for controlling the engine ignition system, and its main function is to control the start and shut down of the engine. The current flameout indication information can be triggered by responding to the user's operation of the flameout switch, and is used to indicate whether the tractor is currently shut down or started.

[0028] Step S102: If the current flameout indication information is a flameout signal, then the operating information corresponding to a plurality of target parameters of the tractor is acquired in real time, wherein the target parameters are operating parameters that characterize the effects on the safe flameout of the tractor.

[0029] In this embodiment, each target parameter may be a parameter corresponding to each safety item of the tractor. Safety items are a series of safety-related matters that need to be properly handled or meet the conditions before the tractor is turned off. Safety items may be directly related to the safety of the tractor's safe turning off and subsequent operations.

[0030] Step S103: for each of the target parameters, the operation information corresponding to the target parameter is compared with the flameout condition corresponding to the target parameter to obtain a comparison result corresponding to the target parameter.

[0031] In this embodiment, multiple target parameters and the flameout conditions corresponding to each target parameter can be preset in the electronic device. The target parameters and the corresponding flameout conditions can be selected and stored according to the actual operating conditions of the tractor, thereby realizing flexible setting of the target parameters and the flameout conditions.

[0032] Step S104: If the comparison results corresponding to the target parameters all meet the corresponding flameout conditions, the tractor is controlled to automatically flameout.

[0033] When the operating information corresponding to the target parameter meets the corresponding flameout condition, the comparison result corresponding to the target parameter is that the flameout condition is met; when the operating information corresponding to the target parameter does not meet the corresponding flameout condition, the comparison result corresponding to the target parameter is that the flameout condition is not met.

[0034] When the comparison results corresponding to each target parameter all meet the shutdown conditions, the tractor is in a state where it can be safely shut down, so that the shutdown signal can be executed to control the tractor to automatically shut down, ensuring the safe shutdown of the tractor, and effectively reducing the possibility of damage to the entire vehicle and engine due to failure to operate the safety items corresponding to the target parameters before shutdown, reducing the damage caused by improper operation such as user negligence when the vehicle is restarted, and automatically judging whether the tractor is allowed to be shut down, reducing the workload of manual inspection and judgment by users.

[0035] In this embodiment, if the comparison results corresponding to each of the target parameters all meet the corresponding flameout conditions, the method further includes the following processing: generating first prompt information, and sending the first prompt information to a prompt device of the tractor, so that the prompt device feeds back the first prompt information to the user.

[0036] The prompt device may be an instrument display, which may display the first prompt information, which may be "the vehicle will be turned off in n seconds, please take all your belongings with you", and the specific value of n may be set according to actual conditions. The prompt device may also be a voice broadcast device, which may broadcast the first prompt information by voice.

[0037] In this embodiment, multiple target parameters may include the vehicle PTO switch status, the vehicle neutral switch status, the vehicle lift position status, the electronic handbrake switch status, the engine speed, the engine coolant temperature, the accelerator pedal opening, the engine oil temperature and the vehicle speed, and multiple shutdown conditions may include the vehicle PTO switch condition, the vehicle neutral switch condition, the vehicle lift position condition, the electronic handbrake switch condition, the engine speed condition, the engine coolant temperature condition, the accelerator pedal opening condition, the engine oil temperature condition and the vehicle speed condition.

[0038] PTO (Power Take Off) is a device on a tractor that outputs part or all of the power to drive the working mechanism of the supporting agricultural machinery. The vehicle PTO switch status is used to indicate whether the PTO has been activated or closed, the vehicle neutral switch status is used to indicate whether the tractor has been put into neutral, the vehicle lift position status is used to indicate the current position of the lift on the tractor (such as the agricultural implement lift device), the electronic handbrake switch status is used to indicate whether the handbrake system has been activated, the engine speed is used to indicate the number of revolutions per minute of the engine crankshaft, the engine coolant temperature is used to indicate the temperature of the coolant when it circulates inside the engine, the throttle pedal opening is used to indicate the opening size of the throttle mechanism when the user presses the throttle pedal, the engine oil temperature is used to indicate the temperature of the oil when it circulates inside the engine, and the vehicle speed is used to indicate the speed of the tractor during driving.

[0039] The vehicle PTO switch condition can be "vehicle PTO switch = disconnected state", the vehicle neutral switch condition can be "vehicle neutral switch = neutral", the vehicle lift position condition can be "vehicle lift position = lowest position", the electronic handbrake switch condition can be "electronic handbrake switch = engaged state", the engine speed condition can be "engine speed = engine idle setting speed", the engine coolant temperature condition can be "engine coolant temperature < maximum coolant limit", the throttle pedal opening condition can be "foot throttle pedal = 0% and hand throttle pedal = 0%", the engine oil temperature condition can be "engine oil temperature < maximum oil limit", and the vehicle speed condition can be "vehicle speed = 0".

[0040] Before shutting down the tractor, make sure the PTO switch is turned off to avoid accidental starting; put the tractor in neutral before shutting down to prevent accidental movement due to the gear not being in neutral after shutting down; make sure the lifter has been lowered to the safe lowest position before shutting down to prevent equipment damage and personal injury; make sure the handbrake switch is engaged before shutting down to ensure that the tractor will not move due to external force after parking; monitor the engine speed before shutting down to ensure that the engine stops at the appropriate speed to avoid damage to the engine caused by sudden shutdown when running at high speed; check the coolant temperature before shutting down to reduce the possibility of engine damage caused by direct shutdown due to excessive coolant temperature; the accelerator pedal opening can help judge the user's intention and the working status of the engine; check the oil temperature before shutting down to reduce the possibility of engine damage caused by direct shutdown due to excessive engine oil temperature; monitor the vehicle speed before shutting down to ensure that the tractor is shut down at low speed or stationary to avoid the danger caused by sudden shutdown when driving at high speed.

[0041] In this embodiment, if at least one of the comparison results corresponding to each of the target parameters does not meet the corresponding flameout condition, the method further includes the following processing: generating second prompt information corresponding to the comparison result that does not meet the flameout condition, and sending the second prompt information to a prompt device of the tractor, so that the prompt device feeds back the second prompt information to the user.

[0042] The second prompt information is used to prompt the user, so that the user can promptly find the target parameters that do not meet the shutdown conditions, and prompt the user to follow various safe shutdown conditions to shut down the vehicle, thereby reducing damage caused by improper operation such as user negligence when the vehicle is restarted.

[0043] In this embodiment, the second prompt information may include at least one of display information and sound and light alarm information, and the prompt device may include at least one of an instrument display and a sound and light alarm device. The instrument display can display the display information, and the sound and light alarm device can make a sound and light alarm according to the sound and light alarm information.

[0044] In this embodiment, the electronic device has preset corresponding relationships between various target parameters and various display information, and the display information corresponding to different target parameters may be different.

[0045] Specifically, if the second prompt information is the display information, the generating of the second prompt information corresponding to the comparison result that does not meet the flameout condition includes: taking the flameout condition corresponding to each comparison result that does not meet the flameout condition as the target flameout condition; When the target parameter corresponding to the target flameout condition is the engine speed, that is, the engine speed> the engine idle speed, the hand accelerator pedal opening and the foot accelerator pedal opening are judged, and when at least one of the hand accelerator pedal opening and the foot accelerator pedal opening is> 0%, the displayed information may be "Please set the hand accelerator pedal opening or the foot accelerator pedal opening to the idle position"; When the target parameter corresponding to the target flameout condition is the engine oil temperature, that is, the engine oil temperature is greater than the maximum oil limit, the display message may be "the engine oil temperature exceeds the maximum oil limit and cannot be immediately flameouted", and the engine needs to maintain 1000 rpm until the engine oil temperature meets the corresponding flameout condition; When the target parameter corresponding to the target flameout condition is the engine coolant temperature, that is, the engine coolant temperature is greater than the maximum coolant limit, the display message may be "the engine coolant temperature exceeds the maximum coolant limit, and cannot be immediately flameouted", and the engine needs to maintain 1000 rpm until the engine coolant temperature meets the corresponding flameout condition; When the target parameter corresponding to the target flameout condition is the vehicle PTO switch state, that is, the vehicle PTO switch state ≠ disconnected state, the displayed information may be "PTO switch is not disconnected, and the flameout cannot be stopped immediately. Please disconnect the PTO switch"; When the target parameter corresponding to the target shutdown condition is the neutral switch state of the vehicle, that is, the neutral switch state of the vehicle ≠ neutral, the displayed information may be "the vehicle is not in neutral, and cannot be shut down immediately, please put the gear in neutral"; When the target parameter corresponding to the target flameout condition is the position state of the vehicle lifter, that is, the position state of the vehicle lifter ≠ the lowest position, the displayed information may be "the vehicle lifter is not in a safe position and cannot be flameouted immediately. Please put the lifter in a safe position"; When the target parameter corresponding to the target shutdown condition is the vehicle speed, that is, the vehicle speed ≠ 0, the displayed information may be "The vehicle has not stopped steadily and cannot be shut down immediately. Please stop the vehicle steadily"; When the target parameter corresponding to the target shutdown condition is the electronic handbrake switch state, that is, the electronic handbrake switch state ≠ the combined state, the displayed information may be "the handbrake switch is not pulled up, and the engine cannot be shut down immediately. Please pull up the vehicle handbrake switch."

[0046] If there are more than two target parameters that do not meet their corresponding flameout conditions, the instrument display can scroll and display multiple display information to prompt the user to perform corresponding operations.

[0047] In this embodiment, if the second prompt information is the sound and light alarm information, the generating of the second prompt information corresponding to the comparison result that does not meet the flameout condition includes: taking the flameout condition corresponding to each comparison result that does not meet the flameout condition as the target flameout condition, and for each target flameout condition, obtaining the level information of the target flameout condition, wherein the level information is a parameter that characterizes the importance of the flameout condition; for each target flameout condition, based on the level information, obtaining the alarm mode corresponding to the target flameout condition, and generating the sound and light alarm information based on the alarm mode.

[0048] The electronic device stores level information corresponding to each flameout condition, which is used to characterize the level of the flameout condition. In this embodiment, the level information may include the first level, the second level, and the third level, wherein the first level may be the highest level, and the multiple flameout conditions corresponding to the first level may include the engine coolant temperature condition and the engine oil temperature condition, the multiple flameout conditions corresponding to the second level may include the vehicle PTO switch state condition, the vehicle neutral switch state condition, the vehicle speed condition, and the electronic handbrake switch state condition, and the multiple flameout conditions corresponding to the third level may include the engine speed condition and the vehicle lift position state condition. The higher the level information, the more important the safety impact of the corresponding flameout condition when the tractor is turned off, and the more the corresponding target parameter operation information needs to be processed first.

[0049] The electronic device also stores the correspondence between the level information and the alarm mode of the sound and light alarm device. The alarm mode may be that the alarm light alarms by flashing at a set flashing frequency. Different level information has different flashing frequencies corresponding to the sound and light alarm information. The higher the level information, the higher the flashing frequency corresponding to the sound and light alarm information can be. For example, the alarm mode corresponding to the first level may be a mode of alarming with a flashing frequency of 3 Hz, the alarm mode corresponding to the second level may be a mode of alarming with a flashing frequency of 2 Hz, and the alarm mode corresponding to the third level may be a mode of alarming with a flashing frequency of 1 Hz.

[0050] By introducing level information and customizing different alarm modes based on the level information (such as different flashing frequencies, tones, volumes or light flashing modes), the urgency and importance of the flameout condition can be more effectively conveyed, allowing users to more quickly identify which target parameters correspond to the operating information that needs to be processed first.

[0051] In this embodiment, when the second prompt information is the display information and the sound and light alarm information, the generating of the second prompt information corresponding to the comparison result that does not meet the flameout condition includes: The flameout condition corresponding to each comparison result that does not meet the flameout condition is taken as a target flameout condition. For each target flameout condition, a target parameter corresponding to the target flameout condition is obtained. According to a correspondence between a preset target parameter and each display information, display information corresponding to the target flameout condition is obtained, and level information of the target flameout condition is obtained. Based on the level information, an alarm mode corresponding to the target flameout condition is obtained, and the sound and light alarm information is generated based on the alarm mode.

[0052] 30 seconds after the second prompt information is generated (the time can be set according to actual conditions), the method of obtaining the operation information corresponding to each of the multiple target parameters of the tractor in real time in step S102 can be re-executed to obtain new operation information corresponding to each target parameter, and re-judge whether each new operation information meets the corresponding shutdown condition. If each comparison result meets the corresponding shutdown condition, the instrument display can display "Please turn off the shutdown switch again" to confirm that the tractor needs to be shut down. When the shutdown signal sent by the user is received again, step S101 is repeated.

[0053] In this embodiment, if multiple target parameters that do not meet the flameout conditions include the vehicle PTO switch state, the vehicle neutral switch state, the vehicle lift position state and the electronic handbrake switch state, the vehicle PTO switch state, the vehicle neutral switch state, the vehicle lift position state and the electronic handbrake switch state are automatically adjusted in sequence until the comparison results corresponding to each of the adjusted target parameters meet the corresponding flameout conditions.

[0054] First, control the vehicle's PTO switch state to the disconnected state, then lower the lifter position to the lowest position (subject to the safe landing of the machine), and force the vehicle's neutral switch state to switch to neutral, and adjust the electronic handbrake switch state to the engaged state. The instrument display can show "PTO switch is disconnected, the vehicle is in neutral, the electronic handbrake is locked, and the vehicle will shut down within 3 seconds."

[0055] By automatically adjusting the status of each target parameter, the user's operation steps and complexity are reduced, and the operation efficiency is improved. The instrument display provides clear feedback information to the user, allowing the user to understand the current status and safety status of the vehicle in a timely manner.

[0056] In this embodiment, after the second prompt information is sent to the prompt device of the tractor, the following processing is also included: repeatedly executing the step of acquiring the operation information corresponding to each of the plurality of target parameters of the tractor in real time until the comparison results corresponding to the respective target parameters meet the flameout condition, or the continuous execution time corresponding to the current flameout indication information exceeds a preset time threshold, and the engine speed does not meet the corresponding flameout condition, and controlling the tractor to release the processing corresponding to the current flameout indication information.

[0057] The preset time threshold can be set according to actual conditions. For example, the preset time threshold can be 120s. If the continuous execution time corresponding to the current flameout indication information exceeds 120s, and there is still target parameter operation information that does not meet the corresponding flameout condition, the instrument display can sound and light alarm to remind the user to confirm the operation information of each target parameter again. If the continuous execution time corresponding to the current flameout indication information exceeds 120s, and the engine speed is greater than the engine idle speed, the flameout processing flow corresponding to the current flameout indication information can be directly released, and step S101 can be re-executed.

[0058] In this embodiment, after step S101, the following processing is further included: if a brake signal of the tractor is received, and the current flameout indication information is a flameout signal, the tractor is controlled to automatically flameout.

[0059] The electronic device is provided with an emergency flameout method, which may include: when the tractor encounters an emergency, the user can step on the brake to generate a brake signal, and keep the current flameout indication information of the flameout switch as a flameout signal for 5 seconds (the time can be set), and can skip the comparison process of the operation information corresponding to all target parameters and the corresponding flameout conditions, and immediately control the tractor to flame out. If the brake is stepped on alone to generate a brake signal or the current flameout indication information of the flameout switch is kept as a flameout signal for 5 seconds, the emergency flameout method will not work, that is, the tractor cannot be immediately controlled to flame out.

[0060] When the time for the current flameout indication information of the flameout switch to switch from the start signal to the flameout signal is less than 0.5s (the time can be set), it can be determined that the flameout signal is a user error operation, and no flameout response is required, that is, there is no need to perform subsequent processing such as obtaining the operating information corresponding to each target parameter.

[0061] Based on the same technical concept, the present application also provides a control device for automatic flameout of a tractor, such as Figure 2 As shown, the control device 200 for automatic shutdown of the tractor mainly includes: The first acquisition module 201 is used to acquire the current flameout indication information of the tractor; The second acquisition module 202 is used to acquire, in real time, the operation information corresponding to each of the plurality of target parameters of the tractor when the current flameout indication information is a flameout signal, wherein the target parameters are operation parameters that characterize the influence on the safe flameout of the tractor; the comparison module 203 is used to compare, for each of the target parameters, the operation information corresponding to the target parameter with the flameout condition corresponding to the target parameter to obtain a comparison result corresponding to the target parameter; The flameout allowing module 204 is used to control the tractor to automatically flameout when the comparison results corresponding to the target parameters all meet the corresponding flameout conditions.

[0062] Optionally, if the comparison results corresponding to the target parameters all meet the corresponding flameout conditions, the device further includes: The first prompt module is used to generate first prompt information and send the first prompt information to the prompt device of the tractor, so that the prompt device feeds back the first prompt information to the user.

If the second prompt information is the sound and light alarm information, the generating of the second prompt information corresponding to the comparison result that does not meet the flameout condition specifically includes: A first acquisition submodule is configured to use the flameout condition corresponding to each comparison result that does not meet the flameout condition as a target flameout condition, and for each target flameout condition, acquire level information of the flameout condition corresponding to the comparison result that does not meet the flameout condition, wherein the level information is a parameter representing the importance of the flameout condition; The second acquisition submodule is used to acquire, for each target flameout condition, an alarm mode corresponding to the target flameout condition based on the level information, and generate the sound and light alarm information based on the alarm mode.

[0065] Optionally, the plurality of target parameters include a vehicle PTO switch state, a vehicle neutral switch state, a vehicle lift position state, and an electronic handbrake switch state; after obtaining the comparison results corresponding to the respective target parameters, the following is further included: A sequential adjustment module is used to automatically adjust the vehicle PTO switch state, the vehicle neutral switch state, the vehicle lift position state and the electronic handbrake switch state in sequence when the target parameters that do not meet the flameout condition include the vehicle PTO switch state, the vehicle neutral switch state, the vehicle lift position state and the electronic handbrake switch state, until the comparison results corresponding to the adjusted target parameters meet the corresponding flameout conditions.

[0066] Optionally, the plurality of target parameters include engine speed, and after the second prompt module, the following further comprises: A repeated execution module is used to repeatedly execute the step of acquiring the operation information corresponding to each of the plurality of target parameters of the tractor in real time until the comparison results corresponding to the respective target parameters meet the flameout condition, or the continuous execution time corresponding to the current flameout indication information exceeds a preset time threshold, and the engine speed does not meet the corresponding flameout condition, and the tractor is controlled to release the processing corresponding to the current flameout indication information.
