To mitigate fluctuations, low-pass filtering is often used to process fuel levels. However, the complex operating conditions of harvesters limit the effectiveness of low-pass filtering. Therefore, accurately identifying fuel tank levels and improving interference resistance have become pressing challenges. Summary of the Invention

DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] The following describes in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following embodiments of the present invention are described in conjunction with the accompanying drawings.

[0020] The solution provided by the embodiment of the present invention can be applied to any application scenario where the fuel level of the fuel tank in the harvester needs to be identified. The solution provided by the embodiment of the present invention can be executed by the vehicle controller on the harvester.

[0021] The embodiment of the present invention provides a possible implementation method, such as Figure 1 As shown in FIG, a flowchart of a method for identifying the fuel level in a harvester tank is provided. The method can be executed by the vehicle controller on the harvester. For the convenience of description, the method provided by the embodiment of the present invention will be described below using the vehicle controller on the harvester as an example of the execution body. Figure 1 As shown in the flowchart, the method may include the following steps: S10, obtaining a plurality of first resistance values ​​corresponding to the fuel level in the fuel tank of the harvester within a first set time; S20, determining a current liquid level recognition result based on a minimum first resistance value among all first resistance values; S30, obtaining a plurality of second resistance values ​​corresponding to each second set time after the first set time; S40, updating the current liquid level recognition result according to all second resistance values ​​corresponding to each second set time.

[0022] Through the method of the present invention, after determining the current liquid level recognition result based on multiple first resistance values ​​corresponding to the first set time, the current liquid level recognition result is updated according to all second resistance values ​​corresponding to each second set time, which can improve recognition accuracy and anti-interference performance.

[0023] The present invention is further described below with reference to the following specific embodiments. Currently, high-precision sensors are often used to improve fuel level accuracy, mitigating the impact of environmental factors. This, however, increases costs. The present invention provides a method for identifying fuel levels in a harvester's fuel tank. This method aims to improve fuel level accuracy without increasing hardware costs, addressing the problem of abnormal fuel level fluctuations caused by the harvester's complex operating conditions and tank sway.

[0024] Based on this, the purpose of the present invention is to overcome the shortcomings of the existing technology and provide a method for identifying the fuel level of a harvester. This method takes the minimum value of the fuel level percentage collected within the first set time after the vehicle is powered on, and then takes the mode value of the fuel level percentage collected within the second set time, thereby solving the problem of abnormal fuel level fluctuations caused by the shaking of the fuel tank under complex working conditions of the harvester.

[0025] Specifically, in this embodiment, a method for identifying the fuel level in a harvester tank may include the following steps: S10, obtaining a plurality of first resistance values ​​corresponding to the fuel level in the fuel tank of the harvester within a first set time; The plurality of first resistance values ​​may be obtained based on a fuel level sensor provided in the harvester. After the harvester is powered on, the fuel level sensor may be controlled to obtain the plurality of first resistance values.

[0026] Optionally, the above-mentioned vehicle controller is a PLC series controller or an STM32 series controller.

[0027] Optionally, the fuel level collector is a float-type fuel level sensor, which is low in cost.

[0028] Optionally, the fuel level collector may also be a high-precision fuel level sensor, which can reduce the impact of environmental factors on sensor acquisition and improve system stability.

[0029] Optionally, after obtaining the multiple first resistance values, the multiple first resistance values ​​may be stored in array A in chronological order of acquisition time, or the multiple first resistance values ​​may be stored in array A and then sorted in chronological order of acquisition time.

[0030] S20, determining a current liquid level recognition result based on a minimum first resistance value among all first resistance values; The liquid level recognition result corresponding to the minimum first resistance value is used as the current liquid level recognition result, which has high accuracy.

[0031] Optionally, one implementation of the above S20 is: S201, performing percentage conversion processing on each first resistance value among all first resistance values ​​to obtain a first percentage corresponding to each first resistance value; S202: Determine a current liquid level recognition result based on the minimum first percentage among all first percentages, that is, use the liquid level recognition result corresponding to the minimum first percentage as the current liquid level recognition result.

[0032] Alternatively, if all first resistance values ​​are stored in array A, the minimum first percentage may be selected from array A.

[0033] Optionally, the method for obtaining the minimum first percentage in array A includes but is not limited to traversing all elements in array A, and eliminating non-minimum first percentages one by one by comparing the sizes of adjacent elements until the minimum first percentage is found.

[0034] Optionally, after obtaining the current level recognition result, the current level recognition result can be uploaded to the harvester's instrument via the CAN bus for display. The instrument can respond promptly to the fuel level update by the normal controller with low latency.

[0035] In order to accurately display the current liquid level identification result, the above-mentioned first setting time should be less than the instrument's own self-test startup time.

[0036] S30, obtaining a plurality of second resistance values ​​corresponding to each second set time after the first set time; Optionally, after obtaining multiple second resistance values ​​corresponding to a second set time each time, all second resistance values ​​corresponding to the second set time may be stored in array B.

[0037] S40, updating the current liquid level recognition result according to all second resistance values ​​corresponding to each second set time.

[0038] Optionally, an implementation of the above S40 is: For all second resistance values ​​corresponding to any second set time, the current liquid level recognition result is updated based on the mode of all second resistance values.

[0039] For all the second resistance values ​​corresponding to any second set time, an implementation method of updating the current liquid level recognition result based on the mode of all the second resistance values ​​is as follows: S401, performing percentage conversion processing on each second resistance value among all second resistance values ​​corresponding to the second set time to obtain a second percentage corresponding to each second resistance value; S402, performing a mode processing on all second percentages corresponding to the second set time to obtain a mode percentage among all second percentages; S403: When the majority percentage corresponding to the second set time exceeds the set percentage, the current liquid level recognition result is updated based on the majority percentage. In other words, the liquid level recognition result corresponding to the majority percentage exceeding the set percentage is used as the latest current liquid level recognition result.

[0040] Optionally, the method further includes: S404: When the corresponding majority percentage within any second set time does not exceed the set percentage, the current liquid level recognition result is not updated.

[0041] If the multiple second resistance values ​​corresponding to each second set time acquired each time are stored in array B, the current liquid level recognition result can be updated based on all the second resistance values ​​in array B.

[0042] The mode percentage in array B can be adjusted and displayed according to different fuel tanks and different working conditions, and has high adaptability to working conditions.

[0043] Optionally, the method for obtaining the mode percentage in array B includes but is not limited to traversing all elements in the array, counting the number of occurrences of each element, comparing and recording the element with the most occurrences and the number of occurrences, and determining the mode percentage.

[0044] Optionally, a wave-breaking plate can be added to the fuel tank to effectively reduce the shaking of the fuel level and enhance the anti-interference ability caused by the shaking of the fuel tank.

[0045] Optionally, the method further includes: S21, determining the upper surface of the fuel tank based on the current liquid level recognition result, and calculating the risk recognition distance between the upper surface of the fuel tank and the highest liquid level surface of the fuel tank; S22, judging whether there is a fuel sloshing noise risk based on the risk identification distance; The area corresponding to the fuel sloshing noise risk is the area in the fuel tank where the possibility of oil impact is high. In this embodiment, the distance between the upper surface of the fuel tank and the highest liquid level of the fuel tank is used as the judgment standard for risk identification.

[0046] In S22, judging whether there is a fuel sloshing noise risk based on the risk identification distance includes: S221: When the vertical distance is less than a certain value, there is a risk of fuel sloshing noise; S222. When the vertical distances are all greater than or equal to a specific value, there is no risk of fuel sloshing noise.

[0047] Among them, the specific value is preferably 25 mm, and includes the page immersed in oil. That is, when the vertical distance in the risk identification distance obtained by the above analysis is less than the specific value of 25 mm, it indicates that there is a risk of fuel sloshing noise in the fuel tank; conversely, when the vertical distances in the risk identification distance obtained by the above analysis are all greater than or equal to the specific value of 25 mm, it indicates that there is no risk of fuel sloshing noise in the fuel tank.

[0048] The above steps have identified whether the fuel tank design has a risk of fuel sloshing noise. Based on the identification results, the following steps can be selectively performed: If a fuel sloshing noise risk is identified, proceed to the risk control step S23 below to complete the design of the internal wave-breaking plate of the fuel tank to effectively control the existing risk. Conversely, if no risk is found after analysis, the design is proven to be good and there is no need to perform the risk control step S23 below. This completes the identification and control of the entire fuel sloshing noise risk.

[0049] S23. When there is a risk of fuel sloshing noise, perform risk control.

[0050] When there is a risk of fuel sloshing noise, reasonable design improvements can be made based on existing analysis to shift risk control forward, effectively avoid the occurrence of risks, and thus save later R&D and improvement costs. When there is a risk of fuel sloshing noise, the risk control step S23 includes: S231. Divide the fuel tank into a risk area and a safety area according to the risk identification distance; The risk zone refers to areas with a high probability of being impacted by oil during fuel tank sloshing. Conversely, the safe zone refers to areas with a very low probability of being impacted by oil. The risk of fuel sloshing noise arises from the presence of risk zones in the fuel tank. This is when the harvester brakes, turns, or drives in a creeping motion. This risk zone causes liquid fuel to strike the inner wall of the fuel tank or its internal components, producing a crashing sound. Therefore, effective risk control requires identifying the risk and safe zones of the fuel tank. Only then can appropriate noise reduction measures be implemented in these risk zones to effectively control the risk of fuel sloshing noise.

[0051] Optionally, the step S231 of dividing the fuel tank into a risk zone and a safety zone according to the risk identification distance includes: S2311. Classify the fuel tank area where the vertical distance is less than a specific value as a risk area; S2312. The fuel tank area with a vertical distance greater than or equal to a specific value is divided into a safety zone.

[0052] Among them, the specific numerical value used in the above-mentioned division of the fuel tank risk zone and the safety zone is consistent with the specific numerical value of 25mm used in step S22 to determine whether the fuel tank has the risk of fuel sloshing noise, and is used to effectively and accurately identify the risk zone and the safety zone of the fuel tank, providing necessary preparation for subsequent risk control.

[0053] S232. Design wave-breaking plates based on risk areas and safety areas; wave-breaking plates include blocking plates, barrier plates and welded columns.

[0054] Among them, the main function of the wave-breaking plate is to reduce the kinetic energy generated by the fuel liquid when the car is in operation, reduce the relative movement speed of the liquid, thereby reducing the impact of the liquid on the surface of the fuel tank and the sound generated by the liquid's own collision.

[0055] To effectively control the risk of fuel sloshing noise, this example still adopts the most widely used and effective control method currently available: rationally designing and arranging wave-breaking panels within the fuel tank to reduce noise. Based on the risk zone and safety zone, step S232 of designing the wave-breaking panels includes: S2321. Install a blocking plate in the risk zone; the gap between the blocking plate and the upper surface of the fuel tank shall not be less than a specified value; the blocking plate is used to lock the oil directly below the risk zone; Among them, the blockade plate refers to a wave-breaking plate used to control the oil shaking directly below the risk area of ​​the fuel tank. The gap between it and the risk area must be greater than or equal to the specific value of 25mm used for identifying the risk area mentioned above, so as to effectively control the oil shaking in the risk area and achieve the effect of effectively controlling the oil shaking in the risk area.

[0056] S2322. Install barrier plates between the risk zone and the safety zone. The barrier plates are connected to the blockade plates to control the flow of oil from the safety zone to the risk zone. Among them, the barrier plate refers to a wave-breaking plate that controls the flow of oil from the safe area to the risk area. It is integrally formed with the blockade plate and has no shape restriction. It is used to reasonably divide or block the risk area and the safe area of ​​the fuel tank to control the unnecessary flow of oil in the fuel tank, thereby effectively avoiding the fuel shaking noise caused by the large-scale flow of oil in the fuel tank.

[0057] S2323. Evenly distributed welding columns are set on the wave-breaking plate; the welding columns are used to weld the blocking plate and the baffle plate to the inside of the fuel tank.

[0058] Among them, there are generally 2-3 welding columns, all distributed on the wave-breaking plate to fix the designed wave-breaking plate in the fuel tank. While ensuring the stability of the wave-breaking plate in the fuel tank, it can also increase the service life of the wave-breaking plate, thereby achieving the effect of long-term and effective control of the risk of fuel sloshing noise.

[0059] In order to better illustrate and understand the principle of the method provided by the present invention, the solution of the present invention is described below in conjunction with an optional specific embodiment. It should be noted that the specific implementation of each step in this specific embodiment should not be understood as limiting the solution of the present invention. On the basis of the principle of the solution provided by the present invention, other implementations that can be thought of by those skilled in the art should also be considered as within the scope of protection of the present invention.

[0060] See also Figure 2 The fuel level identification method of a harvester tank provided in this embodiment may include the following steps: (1) after the vehicle is powered on, the fuel level resistance value (a plurality of first resistance values) is fixedly collected every cycle (first set time) through the vehicle controller and the fuel level sensor and is converted into a percentage.

[0061] (2) The collected fuel level percentages within time T1 (the first set time) are stored in array A, and the fuel level percentages in array A are sorted.

[0062] (3) After array A is sorted, the minimum value (minimum fuel level percentage) in array A is taken as the current fuel level percentage value (current level identification result) and uploaded to the instrument through the CAN bus for display.

[0063] (4) The vehicle controller subsequently stores the fuel level percentage (second percentage) collected within T2 time (second set time) into array B, and performs mode processing on the fuel level percentage in array B.

[0064] (5) After the mode of array B is taken, it is determined whether the mode fuel level percentage P in array B exceeds the set percentage. When the percentage P exceeds the set percentage, the current fuel level percentage (current level identification result) is updated and displayed; otherwise, the previous value (current level identification result) is maintained.

[0065] Through the solution of the present invention, the present invention has the following beneficial effects compared with the prior art: 1. The fuel level processing algorithm adopted by the present invention improves the accuracy of fuel level recognition while requiring low-cost fuel level sensors. At the same time, the mode percentage P in the algorithm can be adjusted and displayed according to different fuel tanks and different operating conditions, and has high adaptability to operating conditions.
