Description

Technical Field

[0001] The present invention relates to the technical field of cotton pickers, and in particular, to an intelligent dust removal control method and system for a cotton picker, and in particular to a cotton picker using the above control system. In addition, it also relates to an electronic device and a computer-readable storage medium. Background Art

[0002] Cotton is a common field cash crop in my country. With the continuous development and progress of agricultural mechanization, the demand for cotton pickers is also growing. Cotton pickers rely on the rotation of the engine fan to generate airflow to cool the oil in the radiator. However, the actual working environment of cotton pickers is relatively harsh, with large dust and debris. It is very easy to have unfavorable conditions such as engine air intake blockage, which affects the air volume passing through the radiator and reduces the heat dissipation efficiency. Therefore, in order to improve the working efficiency of cotton pickers, it is necessary to install a dust removal device at the engine air intake to collect and discharge impurities. At present, most dust removal devices at the air intake of cotton picker engines use a rotating dust suction filter to achieve the purpose of dust removal. However, the dust removal device cannot achieve intelligent start-stop control. If the dust removal device is always working, it will cause engine energy loss and reduce the service life of the dust removal device. If it relies on the driver to manually control the start and stop, it needs to rely on the driver's work experience and increase the driver's workload. In addition, in cold weather, impurities on the filter net help the oil to reach the ideal working temperature faster. If the dust removal device is frequently turned on or turned on for a long time, it will increase the temperature rise time of the oil, causing engine energy loss in vain. In addition, during the rotation of the filter, impurities such as cotton wool and branches are easily accumulated in the gap between the filter and the side surface, which will increase the load of the dust removal device and reduce the dust removal effect. Summary of the invention

[0003] The present invention provides an intelligent dust removal control method and system for a cotton picker, a cotton picker, an electronic device, and a computer-readable storage medium, which can realize intelligent start and stop control of a dust removal device, thereby realizing rapid heating of the hydraulic oil in a cold weather operating environment and avoiding waste of engine power, while ensuring the dust removal effect and preventing blockage of the engine air intake.

The weighted sum of these two output quantities and the previous output quantity is performed to obtain the operating time of the dust removal device.

[0014] Furthermore, after controlling the automatic start and stop of the dust removal device, the following contents are also included:

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Reference Figure 1 The preferred embodiment of the present application provides an intelligent dust removal control method for a cotton picker, comprising the following contents:

[0038] Step S1: collecting the ambient temperature value and the hydraulic oil temperature value of the hydraulic oil tank, and calculating the hydraulic oil temperature change value;

[0039] Step S2: Determine whether the current working condition of the cotton picker is the field operation mode, and determine whether the hydraulic oil temperature value is not greater than the preset minimum temperature threshold. If it is the field operation mode and the hydraulic oil temperature value is not greater than the preset minimum temperature threshold, execute the subsequent steps;

[0040] Step S3: taking the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value as input quantities and the running time of the dust removal device as output quantity to perform fuzzy control, and obtain the running time of the dust removal device;

[0041] Step S4: Controlling the automatic start and stop of the dust removal device based on the running time of the dust removal device.

[0042] It can be understood that the intelligent dust removal control method of the cotton picker of the present embodiment first collects the ambient temperature value and the hydraulic oil temperature value of the hydraulic oil tank, and calculates the hydraulic oil temperature change value. When it is judged that the current working condition of the cotton picker is the field operation mode and the hydraulic oil temperature is not greater than the preset minimum temperature threshold, the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value are used as input quantities, and the operating time of the dust removal device is used as the output quantity for fuzzy control to obtain the operating time of the dust removal device, and finally the dust removal device is controlled to automatically start and stop based on the operating time. The intelligent dust removal control method of the present invention monitors the hydraulic oil temperature, ambient temperature and hydraulic oil temperature rise in real time. When it is determined that the current working condition of the cotton picker is a field working condition and the hydraulic oil temperature is not greater than a preset minimum temperature threshold, it is determined that the current working environment is cold weather. Based on the hydraulic oil temperature, ambient temperature and hydraulic oil temperature rise, the fuzzy control algorithm can automatically calculate the operating time of the dust removal device, thereby realizing intelligent start and stop control of the dust removal device, which not only realizes the rapid heating of the hydraulic oil in the cold weather working environment and avoids the waste of engine power, but also ensures the dust removal effect and prevents the engine air intake from being blocked. The entire control process does not require human intervention, reduces the workload of the driver, and prolongs the service life of the dust removal device.

[0043] It can be understood that in step S1, the ambient temperature value is collected by the ambient temperature sensor installed on the cotton picker, and the hydraulic oil temperature value is collected by the hydraulic oil temperature sensor installed in the hydraulic oil tank. The specific collection frequency can be set according to actual needs, and the hydraulic oil temperature change value is calculated based on the hydraulic oil temperature values ​​collected twice before and after. In addition, at the time of initialization, the default hydraulic oil temperature change value is zero.

[0044] It can be understood that the operation mode of the cotton picker generally includes a field operation mode and a road driving mode. The cotton picker is usually provided with an operation mode switching button. The operation mode of the cotton picker can be switched by operating the operation mode switching button. Therefore, by collecting the state of the operation mode switching button, it can be determined whether the current working condition is the field operation mode. Then, it is determined whether the collected hydraulic oil temperature value is not greater than the preset minimum temperature threshold. In order to ensure that the hydraulic oil has good working characteristics, such as kinematic viscosity, the cotton picker is set with a maximum temperature threshold and a minimum temperature threshold of the hydraulic oil. However, if it is in cold weather, the hydraulic oil temperature will generally be lower than the preset minimum temperature threshold. If the collected hydraulic oil temperature value is less than or equal to the preset minimum temperature threshold, it is determined that the current working environment is cold weather. Therefore, in step S2, only when it is determined that the working condition of the cotton picker is field operation and the environment is cold weather, the subsequent steps are executed. In addition, in other embodiments of the present invention, it is also possible to determine whether the working environment is cold weather based on the collected ambient temperature value. For example, when the ambient temperature value is lower than the preset threshold, it is determined that the current working environment is cold weather. In addition, when it is judged that cotton picking The current operating mode of the machine is road driving mode, or When it is determined that the hydraulic oil temperature value is greater than a preset minimum temperature threshold, the dust removal device is controlled to stop working.

[0045] It is understandable that Figure 2 As shown, in the step S3, the process of taking the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value as input and the running time of the dust removal device as output for fuzzy control to obtain the running time of the dust removal device includes the following:

[0046] Step S31: taking the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value as input quantities, taking the running time of the dust removal device as output quantity, and using the membership function to fuzzify the input quantity and the output quantity respectively;

[0047] Step S32: using the rule of "IF A and B or C then D" to set a fuzzy rule base, wherein A represents the fuzzy hydraulic oil temperature value, B represents the fuzzy ambient temperature value, C represents the fuzzy hydraulic oil temperature change value, and D represents the fuzzy dust removal device operation time;

[0048] Step S33: Perform fuzzy reasoning based on the fuzzified input and output quantities and the set fuzzy rule base to obtain the operating time of the dust removal device.

[0049] Specifically, the hydraulic oil temperature value T, the ambient temperature value Te and the hydraulic oil temperature change value ΔT collected at a certain moment are used as input variables, and the running time t of the dust removal device is used as the output variable. The input variables and the output variables are fuzzified using a triangular membership function. Of course, in other embodiments of the present invention, a Gaussian membership function can also be used for fuzzification. Optionally, in order to simplify the calculation, the hydraulic oil temperature value T is converted into a dimensionless parameter before the input variable is fuzzified. The conversion method is T / (T H -T L ), where T H and T L For example, in one embodiment of the present invention, the results of fuzzifying three input variables using the triangular membership function are shown in Tables 1 to 3, and the results of fuzzifying the output variables are shown in Table 4.

[0051]

[0052] Table 2. Membership degree of ambient temperature fuzzy variables

[0053]

[0054] Table 3. Membership degree of fuzzy variables of hydraulic oil temperature change

[0055]

[0056] Table 4. Membership of running time fuzzy variables

[0057]

[0058] Among them, the fuzzy set of hydraulic oil temperature value T(%) is: extremely small (VS), small (S), medium (M), large (L), and extremely large (VL), and the range of variation is: 0-100; the fuzzy set of ambient temperature value Te(℃) is: extremely cold (VC), cold (C), normal (N), hot (H), and extremely hot (VH), and the range of variation is: 0-50℃; the fuzzy set of hydraulic oil temperature change value ΔT(℃) is: negative large (NB), negative small (NS), zero (ZO), positive small (PS), and positive large (PB), and the range of variation is: -3-3; the fuzzy set of running time t(min) is: extremely short (VS), short (S), long (L), relatively long (ML), and extremely long (VL), and the range of variation is: 1-9.

[0059] Then, the fuzzy rule base is set using the rule of "IF A and B or C then D", where A represents the fuzzy hydraulic oil temperature value, B represents the fuzzy ambient temperature value, C represents the fuzzy hydraulic oil temperature change value, and D represents the fuzzy dust removal device operation time. For example, according to Tables 1 to 4 above, it can be summarized that there are 5×5×5 fuzzy control rules. For example, some fuzzy rules can be expressed as: IF T=VS and Te=VC andΔT=NB then t=VS; IF T=VL or Te=VH andΔT=PB then t=VL.

[0060] Next, the output t is clarified. For example, the Mamdani algorithm is first used to obtain the output results of each single control rule, and then all the output results that meet the conditions are combined to obtain the total fuzzy Output, then according to the maximum membership The function method finds the average of the interval corresponding to the maximum membership function and obtains the actual The actual output is the running time t of the dust removal device. Among them, the Mamdani algorithm and the maximum membership function method belong to the existing algorithms, and the specific principles are not repeated here. Of course, in other embodiments of the present invention, the existing Zadeh algorithm can also be used to infer the output result of a single control rule, and then the existing summation average method or median method can be used to obtain the final result.

[0061] It can be understood that in step S4, the dust removal device is automatically started and stopped based on the running time t obtained in step S3. When starting, the dust removal fan is started first and then the dust removal motor is started, and then after running for t min, the dust removal fan and the dust removal motor are turned off.

[0062] Optionally, in step S4, after controlling the dust removal device to automatically start and stop, the following contents are also included:

[0063] The working current of the dust removal motor is monitored in real time. If it is detected that the working current of the dust removal motor is greater than the maximum working current, the dust removal motor is controlled to reverse.

[0064] Specifically, after the dust removal device starts working, the working current value of the dust removal motor is obtained in real time from the communication message of the digital distribution box. If the working current of the dust removal motor is monitored to be greater than the maximum working current, it means that there are more impurities between the filter and the dust collection component, and more impurities are attached to the brush, resulting in a larger motor load. At this time, the dust removal motor needs to be controlled to reverse to remove impurities and improve the rotary dust removal effect and heat dissipation efficiency. When it is monitored that the working current of the dust removal motor is not greater than the maximum working current, the dust removal motor is controlled to rotate forward.

[0065] It can be understood that the present invention can determine the degree of impurity adhesion on the brush in real time by monitoring the working current of the dust removal motor in real time, and remove impurities by automatically controlling the reversal of the dust removal motor, thereby realizing the self-cleaning function of the brush and improving the dust removal effect and heat dissipation efficiency.

[0066] Optionally, in step S2, before determining the current working condition of the cotton picker, the following steps are also included:

[0067] Monitor whether the state of the dust removal device is normal, and determine whether the hydraulic oil temperature value is less than the preset maximum temperature threshold. If the state of the dust removal device is normal and the hydraulic oil temperature value is less than the preset maximum temperature threshold, execute subsequent steps.

[0068] Specifically, when the dust removal motor is not short-circuited, overloaded, etc., and the electromagnetic clutch is not in a short-circuit state, the dust removal device is judged to be in a normal state, and when the hydraulic oil temperature value is judged to be less than the preset maximum temperature threshold, the subsequent steps are continued. If the dust removal device is judged to be abnormal, or the hydraulic oil temperature is greater than or equal to the preset maximum temperature threshold, the dust removal device is controlled not to operate, and an alarm prompt message may also be issued.

[0069] Preferably, the intelligent dust removal control method also collects the water temperature value of the engine water tank and the lubricating oil temperature value of the transfer case, calculates the water temperature change value and the lubricating oil temperature change value, and uses the water temperature value and the water temperature change value, the lubricating oil temperature value and the lubricating oil temperature change value as two sets of input variables, which respectively replace the hydraulic oil temperature value and the hydraulic oil temperature change value for fuzzy control, and two output quantities can be obtained. The weighted sum of these two output quantities and the previous output quantity is performed to obtain the operating time of the dust removal device.

[0070] Specifically, three radiators are generally installed on the cotton picker, one of which is used to dissipate heat for the hydraulic oil in the hydraulic oil tank, one is used to dissipate heat for the water in the engine water tank, and the other is used to dissipate heat for the lubricating oil in the transfer case. The cooling airflow generated by the rotation of the engine fan will be unevenly distributed to the three radiators, resulting in different air volumes allocated to each radiator. Therefore, in order to more comprehensively and accurately evaluate the blockage degree of the engine air inlet and the overall heat dissipation efficiency, the present invention also installs temperature sensors in the engine water tank and the transfer case, so that the water temperature value and the lubricating oil temperature value can be collected in real time, and the water temperature change value and the lubricating oil temperature change value collected twice before and after are calculated respectively. Then, the water temperature value and the water temperature change value are used as a set of input variables, and the lubricating oil temperature value and the lubricating oil temperature change value are used as another set of input variables, and the hydraulic oil temperature value and the hydraulic oil temperature change value are replaced respectively for fuzzy control, and two output variables are obtained, that is, two results of the running time of the dust removal device are obtained. For example, the water temperature value and the water temperature change value replace the hydraulic oil temperature value and the hydraulic oil temperature change value, and the above-mentioned dust removal device state judgment, cotton picker working condition judgment, fuzzy control and other processes are performed in sequence to obtain an output result with the water temperature value, the water temperature change value and the ambient temperature value as input variables; similarly, the lubricating oil temperature value and the lubricating oil temperature change value replace the hydraulic oil temperature value and the hydraulic oil temperature change value, and an output result with the lubricating oil temperature value, the lubricating oil temperature change value and the ambient temperature value as input variables can also be obtained. Finally, the three output results are weighted and summed to calculate the final running time, where the weighted summation formula is: t=w1t1+w2t2+w3t3, t1 represents the running time obtained with the hydraulic oil temperature value, hydraulic oil temperature change value, and ambient temperature value as input variables, t2 represents the running time obtained with the water temperature value, water temperature change value, and ambient temperature value as input variables, t3 represents the running time obtained with the lubricating oil temperature value, lubricating oil temperature change value, and ambient temperature value as input variables, w1, w2, and w3 represent weight coefficients respectively, and the weight coefficients can be set according to experience. Preferably, the three weight coefficients are determined by counting the ratio of the number of times the hydraulic oil temperature value, water temperature value and lubricating oil temperature value exceed the preset high temperature threshold value within a period of time. For example, it is counted that the number of times the hydraulic oil temperature value exceeds the preset high temperature threshold value within a period of time is 10 times, the number of times the water temperature value exceeds the preset high temperature threshold value is 5 times, and the number of times the lubricating oil temperature value exceeds the preset high temperature threshold value is 5 times, then the ratio is 2:1:1, and the three weight coefficients w1, w2 and w3 are 0.5, 0.25 and 0.25 respectively.

[0071] It can be understood that the present invention also collects the water temperature value of the engine water tank and the lubricating oil temperature value of the transfer case, and can evaluate the heat dissipation effect of the engine water tank radiator and the transfer case radiator, and perform fuzzy control to obtain two output results respectively, and then perform weighted summation of these two output results and the output result obtained based on the hydraulic oil tank temperature monitoring, comprehensively considering the three radiators on the cotton picker, and can more comprehensively and accurately evaluate the heat dissipation effect of the whole machine, thereby improving the accuracy of the automatic start and stop control of the dust removal device. Moreover, the weight coefficient during weighted summation is obtained based on the daily temperature exceeding standard statistical data, which further improves the control accuracy.

[0072] In addition, if Figure 3 As shown, another embodiment of the present invention further provides an intelligent dust removal control system for a cotton picker, preferably using the intelligent dust removal control method as described above, the system comprising:

[0073] The temperature acquisition module is used to collect the ambient temperature value and the hydraulic oil temperature value of the hydraulic oil tank, and calculate the hydraulic oil temperature change value;

[0074] The working condition judgment module is used to judge whether the current working condition of the cotton picker is the field operation mode, and judge whether the hydraulic oil temperature value is not greater than the preset minimum temperature threshold. If it is the field operation mode and the hydraulic oil temperature value is not greater than the preset minimum temperature threshold, the subsequent steps are executed;

[0075] A fuzzy control module is used to perform fuzzy control using the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value as input quantities and the operating time of the dust removal device as output quantity to obtain the operating time of the dust removal device;

[0076] The dust removal control module is used to control the automatic start and stop of the dust removal device based on the running time of the dust removal device.

[0077] It can be understood that the intelligent dust removal control system of the cotton picker of this embodiment first collects the ambient temperature value and the hydraulic oil temperature value of the hydraulic oil tank, and calculates the hydraulic oil temperature change value. When it is judged that the current working condition of the cotton picker is the field operation mode and the hydraulic oil temperature is not greater than the preset minimum temperature threshold, the hydraulic oil temperature value, the ambient temperature value and the hydraulic oil temperature change value are used as input quantities, and the operating time of the dust removal device is used as the output quantity for fuzzy control to obtain the operating time of the dust removal device, and finally the dust removal device is controlled to automatically start and stop based on the operating time. The intelligent dust removal control system of the present invention monitors the hydraulic oil temperature, ambient temperature and hydraulic oil temperature rise in real time. When it is determined that the current working condition of the cotton picker is a field working condition and the hydraulic oil temperature is not greater than the preset minimum temperature threshold, it is determined that the current working environment is cold weather. Based on the hydraulic oil temperature, ambient temperature and hydraulic oil temperature rise, the fuzzy control algorithm can automatically calculate the operating time of the dust removal device, thereby realizing intelligent start and stop control of the dust removal device, which not only realizes the rapid heating of the hydraulic oil in the cold weather working environment and avoids the waste of engine power, but also ensures the dust removal effect and prevents the engine air intake from being blocked. The entire control process does not require human intervention, reduces the workload of the driver, and prolongs the service life of the dust removal device.

[0078] In addition, the intelligent dust removal control system also includes:

[0079] The current monitoring module is used to monitor the working current of the dust removal motor in real time. If it is monitored that the working current of the dust removal motor is greater than the maximum working current, the dust removal control module controls the dust removal motor to reverse.

[0080] It can be understood that the various modules of the system embodiment correspond to the various steps of the above method embodiment, so the specific working principles of each module are not repeated here, and the corresponding references can be made to the various steps of the above method embodiment.

[0081] In addition, another embodiment of the present invention further provides a cotton picker, which preferably adopts the intelligent dust removal control system as described above.

[0082] In addition, another embodiment of the present invention further provides an electronic device, including a processor and a memory, wherein the memory stores a computer program, and the processor executes the steps of the above method by calling the computer program stored in the memory.

[0083] In addition, another embodiment of the present invention further provides a computer-readable storage medium for storing a computer program for performing intelligent dust removal control of a cotton picker, wherein the computer program executes the steps of the method described above when running on a computer.

[0084] The general form of computer readable storage media includes: floppy disk, flexible disk, hard disk, magnetic tape, any other magnetic medium, CD-ROM, any other optical medium, punch cards, paper tape, any other physical medium with a pattern of holes, random access memory (RAM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), flash erasable programmable read-only memory (FLASH-EPROM), any other memory chip or cartridge, or any other medium that can be read by a computer.
