The research shows that the harvesting machine is a mechanical device for harvesting crops, and the working environment is a complex and severe environment in application, and generally has the characteristics of much dust, wheat bran, high temperature, humidity, large vibration and the like. The engine is used as a power source of harvesting machinery, the heat dissipation performance is particularly important, the air inlet of the engine heat dissipation fan is of a screen structure, and the engine heat dissipation fan is easy to be blocked in harvesting operation in a high-temperature dusty environment, so that the heat dissipation effect is poor.
In the prior art, a mode of manually cleaning the air inlet at regular time or mechanically cleaning the air inlet is adopted, such as rotary cleaning of a hairbrush, and the simple cleaning mode can not timely and effectively clean sundries blocked by the air inlet, so that the engine is easy to overheat.
Based on the above, the embodiment of the application provides a dust removal control method in a harvesting machine, so that sundries blocked by an air inlet can be effectively removed by controlling a cooling fan of an engine in the harvesting machine to perform back blowing, and the overheat risk of the engine is reduced.
Referring to fig. 1 and fig. 2, fig. 1 is a flowchart of a dust removal control method in a harvesting machine according to an embodiment of the application, and fig. 2 is a schematic structural diagram of the harvesting machine according to an embodiment of the application. The dust removal control method provided by the embodiment of the application is applied to a controller in a harvesting machine. As shown in fig. 2, the harvesting machine includes a manual switch, an operating clutch state, a water temperature sensor, a hydraulic oil temperature sensor, a fan blowback solenoid valve output, a display screen, and a controller.
As shown in fig. 1, the method includes:
S101, determining a harvesting operation state of the harvesting machine.
In this step, the controller may determine the harvesting operation status by the status of each working clutch in the harvesting machine. Main clutch in the harvesting machine is power master control, header clutch manages harvesting parts, and grain unloading clutch is special for grain unloading.
In one possible implementation, step S101 may include:
and when at least one of the main clutch, the bridge clutch and the grain unloading clutch of the harvesting machine is in a combined state, determining that the harvesting operation state is in operation.
And S102, when the harvesting operation state is determined to be in operation, starting operation timing, and generating an automatic back blowing control signal according to the temperature parameter information of the harvesting machine.
Wherein the temperature parameter information comprises parameter values of temperature parameters and/or change information of the parameter values. More specifically, the temperature parameters include engine water temperature and hydraulic oil temperature.
In one possible implementation, step S102 may include:
and a1, continuously monitoring the water temperature value and the hydraulic oil temperature value.
And a2, when the water temperature value is larger than a first preset threshold value or the hydraulic oil temperature value is larger than a second preset threshold value, generating an automatic back blowing control signal to control the cooling fan to execute back blowing.
And a3, after the back blowing of the cooling fan is finished, waiting for a preset period.
And a4, responding to the end of the preset period, and judging whether the water temperature value is still greater than a first preset threshold value or whether the hydraulic oil temperature value is still greater than a second preset threshold value in a preset time window.
And a5, if the water temperature value is still greater than the first preset threshold value or the hydraulic oil temperature value is still greater than the second preset threshold value, generating an automatic back blowing control signal again to control the cooling fan to execute back blowing again.
And a step a6 of waiting for a preset period again after the back blowing of the cooling fan is finished again, and judging whether the water temperature value is still greater than a first preset threshold value or whether the hydraulic oil temperature value is still greater than a second preset threshold value in a preset time window in response to the end of the preset period, namely, circularly executing the steps a2 to a4 until the water temperature value is smaller than or equal to the first preset threshold value and the hydraulic oil temperature value is smaller than or equal to the second preset threshold value, and returning to execute the step of continuously monitoring the water temperature value and the hydraulic oil temperature value, namely, the step a1.
In one example, under conditions that satisfy the vehicle operating condition (when the harvesting operating condition is operating), if the water temperature is greater than 92 ℃ or the hydraulic oil temperature is greater than 85 ℃, a first blowback is performed, waiting 30 seconds after the first blowback is completed, continuously monitoring the water temperature and the hydraulic oil temperature during 31-35 seconds, and if the detected water temperature is still greater than 92 ℃ during 31-35 seconds or the hydraulic oil temperature is still greater than 85 ℃, performing a second blowback. Otherwise, turning to a starting point and waiting for re-triggering;
And starting to count 5min after the second back flushing, if the water temperature is less than or equal to 92 ℃ and the hydraulic oil temperature is less than or equal to 85 ℃, ending the counting, turning to a starting point to wait for retriggering, and if the water temperature is still greater than 92 ℃ or the hydraulic oil temperature is still greater than 85 ℃ after the counting 5min, executing the third back flushing.
After the third back blowing, if the temperature is not reduced yet, back blowing is performed for 5 minutes for the fourth time, the fifth time, the sixth time and the third time.
Further, when the number of times of controlling the cooling fan to perform back blowing exceeds a preset number of times threshold, if the water temperature value is still greater than a first preset threshold or the hydraulic oil temperature value is still greater than a second preset threshold within a preset time window, an alarm signal is generated.
Corresponding to the example, after the fourth back flushing, timing is performed for 30 seconds, if the water temperature is still greater than 92 ℃ or the hydraulic oil temperature is greater than 85 ℃ after 30 seconds, an alarm signal is generated, a message is sent to an instrument to alarm, and after the alarm, the water temperature is required to be equal to or less than 92 ℃ and the hydraulic oil temperature is required to be equal to or less than 85 ℃, the alarm is released.
The alarm prompt output CAN be CAN message sent to display screen prompt, through bus communication, on screen with text and animation prompt, or hard wire signal sound-light alarm is replaced, hard wire signal is connected with sound-light alarm through hard wire, sound and light prompt.
In another possible embodiment, when the temperature parameter information is information of a change in a parameter value of a temperature parameter, step S102 may include:
and b1, continuously monitoring the water temperature value and the hydraulic oil temperature value.
And b2, reading change information of the water temperature value in real time after the water temperature value is larger than a third preset threshold value.
And b3, reading the change information of the hydraulic oil temperature value in real time after the hydraulic oil temperature value is larger than a fourth preset threshold value.
And b4, when the change information of the water temperature value and/or the change information of the hydraulic oil temperature value indicate that the temperature rise value in the preset temperature rise window is greater than the preset temperature rise threshold value, generating an automatic back blowing control signal to control the cooling fan to execute back blowing.
Here, the controller monitors the change of the water temperature value and the hydraulic oil temperature value in real time, and judges the temperature rise. In the normal state, the water temperature and the hydraulic oil temperature change at a slower rate, and the method belongs to a slow change process. And when more dust exists, the heat dissipation system can be seriously affected, so that the temperature rise is faster.
In one example, after the water temperature is detected to be greater than 65 ℃, the water temperature change is read in real time, when the water temperature change is less than 5 ℃ in 3 minutes, the temperature rise speed is judged to be normal, when the water temperature change is greater than 5 ℃ in 3 minutes, the temperature rise is judged to be too fast, the suction system is judged to be unsmooth and back-blowing dust removal is needed, after the hydraulic oil temperature is detected to be greater than 40 ℃, the oil temperature change is read in real time, when the water temperature change is less than 5 ℃ in 3 minutes, the temperature rise speed is judged to be normal, and when the water temperature change is greater than 5 ℃ in 3 minutes, the temperature rise speed is judged to be too fast, the suction system is judged to be unsmooth and back-blowing dust removal is needed.
In this way, the embodiment of the application can carry out logic judgment by judging the temperature rise, and carry out back-blowing dust removal when judging the rapid temperature rise, thereby effectively avoiding hysteresis measures of reprocessing after the temperature is too high, further improving the processing rate, better protecting the system and preventing overheat.
In another possible embodiment, when the temperature parameter information is information of a change in a parameter value of a temperature parameter, step S102 may further include:
And step c1, predicting the change trend of the parameter value of the temperature parameter according to the change information of the parameter value of the temperature parameter of the harvesting machine.
And c2, when the change trend indicates that the water temperature value is greater than a first preset threshold value or the hydraulic oil temperature value is greater than a second preset threshold value after the prediction period, generating an automatic back blowing control signal to control the cooling fan to execute back blowing.
Here, according to the change information of the parameter value of the temperature parameter of the harvesting machine, i.e. the history change situation, the change trend of the parameter value, i.e. the future change situation, can be predicted.
When the change trend indicates that the water temperature value is larger than the first preset threshold value or the hydraulic oil temperature value is larger than the second preset threshold value after a shorter prediction period, the generation of an automatic back blowing control signal can be triggered to control the cooling fan to execute back blowing, hysteresis measures of reprocessing after the temperature is too high can be effectively avoided, so that the processing rate is improved, a better protection system is realized, and overheating is prevented.
And S103, generating a timing blowback control signal in response to the timing of the job reaching a preset period.
In the step, the operation timing can be started from the condition that the vehicle operation state is met, the timing is stopped when the vehicle operation state is not met, the preset period can be set according to the requirement, for example, the back flushing control signal is timed by taking 20 minutes as one period, and the back flushing is executed once.
S104, responding to the received manually triggered fan blowback signal, and generating a manual blowback control signal.
The manual triggering mode in the embodiment of the application CAN adopt a self-recovery rocker switch or a panel adopting a CAN bus communication mode, and CAN manually start back blowing.
In one example, when the controller is powered on, a manual fan blowback switch signal is received, the fan blowback solenoid valve and the enable solenoid valve are immediately powered on. If the manual trigger signal is less than or equal to 5s, the fan back-blowing electromagnetic valve and the enabling electromagnetic valve are powered on for 5s, if the trigger signal is more than 5s and less than or equal to 10s, the pressing time is executed, and if the trigger signal is more than 10s, the fan back-blowing electromagnetic valve and the enabling electromagnetic valve are powered on for 10s.
S105, controlling a cooling fan of an engine in the harvesting machine to execute back blowing according to the automatic back blowing control signal and/or the timing back blowing control signal and/or the manual back blowing control signal.
In the step, the controller controls the execution of back flushing according to the corresponding control strategy according to the received first back flushing control signal, and clears the operation timing. Namely, after any condition in manual, automatic and timing triggers back blowing, the timing is cleared.
In the process of executing back blowing, responding to a newly received second back blowing control signal, judging whether the priority of the second back blowing control signal is greater than that of the first back blowing control signal, and if so, interrupting executing back blowing according to the first back blowing control signal, and converting into executing back blowing according to the second back blowing control signal. The manual blowback control signal has a higher priority than the automatic blowback control signal, and the automatic blowback control signal has a higher priority than the timing blowback control signal. The first blowback control signal and the second blowback control signal include an automatic blowback control signal, a timed blowback control signal, and a manual blowback control signal.
For example, in the automatic blowback process, if a manual blowback control signal is received (for example, a manual fan blowback switch signal is received, or a manual fan blowback signal CAN message is received), manual blowback is performed, and after the completion, the timer 30S is timed or automatic.
The dust removal control method in the harvesting machine combines the harvesting operation state of the harvesting machine, provides various modes of automatic, timing and manual control for a cooling fan of an engine to execute back blowing, effectively eliminates sundries blocked by an air inlet and reduces the overheat risk of the engine, wherein the manual control mode ensures subjective operability, the timing control mode ensures the frequency of timing cleaning, and the automatic control mode according to the parameter value of a temperature parameter and the change information of the parameter value ensures the back blowing timeliness under the condition of high temperature.
