Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0023] First, the application scenarios to which this application is applicable are introduced. This application can be applied to agricultural production.

[0024] With the acceleration of agricultural modernization, the demand for intelligent and modernized "farming, management and harvesting" links is increasing. In order to optimize agricultural production, the development and application of yield monitoring systems has become particularly important. It can collect and analyze key data such as operating area, grain yield per mu and location information, and provide a scientific basis for variable sowing, fertilization, spraying and field management.

[0025] The current yield measurement system mainly uses photoelectric, weighing and radiation technologies. However, these technologies have their own limitations: the photoelectric type is easily affected by the moisture content, bulk density and impurities of the grain, resulting in a decrease in the accuracy of continuous operation; the weighing type has high accuracy, but is inefficient when applied on a large scale; the radiation type is harmful to human health and is difficult to be widely commercialized.

[0026] Based on this, the embodiments of the present application provide a crop yield monitoring method and a crop yield monitoring system, aiming to improve the accuracy of crop yield detection.

[0027] See also Figure 1 , Figure 1 This is a flow chart of a crop yield monitoring method provided in an embodiment of the present application. Figure 1 As shown in , the crop yield monitoring method provided by the embodiment of the present application includes:

[0028] S101. Identify whether the harvester meets the crop yield monitoring conditions based on the rotation speed of the grain elevator of the harvester and the crop flow in the grain elevator.

[0029] Here, the grain elevator is used to lift crops into the grain transport auger barrel of the harvester. The grain elevator is a component on the harvester, which is used to lift the harvested crops (such as rice, wheat and other grains) from the ground or low places to the grain transport auger barrel of the harvester for subsequent transportation, threshing and storage. The crop flow rate refers to the amount of crops passing through the grain elevator per unit time. The crop yield monitoring condition refers to judging whether the harvester is in a state or condition suitable for crop yield monitoring.

[0030] In a preferred example of the present application, whether the harvester meets the crop yield monitoring condition is identified in the following manner:

[0031] When the rotation speed of the grain elevator is not less than the maximum rotation speed and the crop flow in the grain elevator is greater than the preset flow, it is determined that the harvester meets the crop yield monitoring conditions. When the rotation speed of the grain elevator is not less than the maximum rotation speed and / or the crop flow in the grain elevator is less than the preset flow, it is determined that the harvester does not meet the crop yield monitoring conditions.

[0032] In a preferred example of the present application, whether the crop flow in the grain elevator exceeds the preset flow is determined by:

[0033] The crop flow in the grain elevator is detected by the voltage signal of the impulse sensor. When the voltage value of the voltage signal of the impulse sensor is higher than the preset voltage value, it is determined that the crop flow in the grain elevator exceeds the preset flow.

[0034] Here, the impulse sensor is arranged at the top of the grain elevator. The impulse sensor is a sensor that can detect and measure the impact force or momentum change. In the embodiment of the present application, the impulse sensor is arranged at the top of the grain elevator to detect the flow of crops passing through the grain elevator and convert it into a voltage signal. The preset voltage value refers to a voltage standard set in advance. When the voltage signal output by the impulse sensor exceeds this voltage standard, it is determined that the crop flow in the grain elevator exceeds the preset flow. The voltage signal of the impulse sensor exchanges data with the controller of the harvester in the form of CAN communication.

[0035] S102: If the harvester meets the crop yield monitoring conditions, a voltage signal from an impulse sensor is received to obtain first crop yield data.

[0036] In a preferred example of the present application, the voltage value of the voltage signal is subtracted from the voltage value of the calibration signal to obtain the actual voltage value, and the calibration signal indicates the signal emitted by the impulse sensor when the grain elevator is unloaded at the maximum speed.

[0037] Here, the calibration signal refers to the signal emitted by the impulse sensor when the grain elevator is unloaded at the maximum speed, which is used to calibrate or adjust the output of the sensor in order to more accurately measure the crop yield. When different harvester models are vibrated, the impulse sensor outputs different voltage signals. Therefore, it is necessary to record and save the impulse sensor signals of the grain elevator when it is unloaded under different models, so as to calculate the effective voltage signal output by the impulse sensor during harvesting. In order to avoid misusing the vibration calibration function when the vehicle has not entered the harvesting vibration state, resulting in inaccurate calculation of yield data, the grain elevator speed sensor is used to limit the conditions for entering the vibration calibration. The output signal of the grain elevator speed sensor is an analog signal. After receiving it, the controller calculates the real-time grain elevator speed data through a certain conversion relationship. As the main clutch throttle is increased to the maximum, the grain elevator speed stabilizes near the maximum value. The maximum speed of the grain elevator of different models is different. Only when the real-time speed reaches the maximum speed of the grain elevator of the current model, the vibration calibration function can be used normally.

[0038] The step of receiving the voltage signal of the impulse sensor to obtain the first yield data of the crop includes: converting the actual voltage value into the initial yield data of the crop, and obtaining the first yield data according to the initial yield data and the rotation speed of the grain elevator.

[0039] The first yield data refers to the crop yield data obtained through preliminary measurement and calculation. In the embodiment of the present application, the first yield data is obtained by converting the actual voltage value into the initial yield data and correcting it according to the rotation speed of the grain elevator. The speed directly affects the grain transportation efficiency and the overall working efficiency of the harvester. There is a certain corresponding relationship between the rotation speed and the yield. For example, when the speed increases, it may mean that the harvester is processing more crops, which may produce a higher yield. But at the same time, too fast a speed may also cause the loss or damage of grains, thereby affecting the actual yield. Therefore, after obtaining the initial yield data, it is necessary to correct it according to the rotation speed of the grain elevator. This correction process can establish an accurate correction model based on the relationship between the rotation speed and the yield. Through this model, the initial yield data can be adjusted according to the actual rotation speed data, so as to obtain more accurate and reliable first yield data.

[0040] S103. According to the harvesting status of the harvester's header, the first yield data is corrected to obtain the second yield data.

[0041] Here, the harvesting state of the harvesting platform refers to the working state of the harvesting platform on the harvester, including full-width harvesting, part-full-width harvesting, etc. The harvesting state of the harvesting platform is used as a basis for correcting the first yield data to obtain more accurate second yield data. For example, if the harvesting platform is in a part-full-width harvesting state, the first yield data may need to be adjusted to reflect the actual harvesting efficiency.

[0042] Below through Figure 2 The steps of correcting the first yield data to obtain the second yield data are introduced.

[0043] Figure 2 A flow chart for obtaining second production data provided in an embodiment of the present application.

[0044] S201. Identify the target voltage interval within which the actual voltage value falls, so as to determine the target harvesting state corresponding to the target voltage interval.

[0045] Here, multiple voltage intervals are pre-set, each voltage interval corresponds to a harvesting state of the harvesting platform, and the target voltage interval refers to a specific interval within a certain range into which the actual voltage value of the impulse sensor falls. By identifying which target voltage interval the actual voltage value falls into, the current harvesting state can be preliminarily judged.

[0046] S202: Determine a target correction strategy corresponding to the target harvesting state according to the target harvesting state.

[0047] Here, the target correction strategy may include adjusting the proportion of yield data, increasing or decreasing specific yield values, or applying a certain mathematical model for correction, such as the crop flow segmentation model, which aims to more accurately reflect the actual yield of the crop based on the actual harvesting status.

[0048] S203: Correct the first production data according to the target correction strategy to obtain second production data.

[0049] return Figure 1 , S104, displaying the second yield data on the on-board display terminal of the harvester, and uploading the second yield data to the cloud platform.

[0050] Here, the on-board display terminal is used to display the second yield data in real time, so that the driver can intuitively understand the current crop yield situation. The cloud platform is used to receive and store the second yield data uploaded from the harvester for subsequent data analysis, processing or visualization. It can be uploaded to the cloud platform through the on-board TBox, which helps agricultural managers better understand the growth and yield distribution of crops, and make more scientific decisions.

[0051] Through the intelligent display terminal, users can interact with this impulse yield monitoring system in real time. The main interface can view real-time yield per mu, real-time work efficiency, real-time harvesting efficiency, real-time grain moisture and other real-time yield-related data and cumulative yield wet weight, cumulative yield dry weight, average yield per mu, average work efficiency, average harvesting efficiency, average grain moisture, total harvesting work area and other average yield-related data, and can also see the real-time generated yield map or moisture map.

[0052] After the operation data is saved, you can view the output map overview of the operation in the operation history, view and export the operation data, view the relevant working information of the impulse output monitoring system in the diagnosis interface, set or calibrate the system parameters in the setting interface, and when the system is abnormal, an alarm message will appear at the top of the screen.

[0053] In a preferred example, after the harvester operation is completed, the actual weighing mass is input into the intelligent display terminal, and the controller automatically updates the yield calibration coefficient. In order to meet the accuracy of the impulse system yield measurement under various harvesting conditions and operating conditions, harvesting operations under full-width and non-full-width conditions can be performed during harvesting. After the operation is completed, the required multiple operation data are selected on the display terminal, and the actual weighing values ​​are input respectively for joint calibration. The system will automatically establish a calibration curve to improve the accuracy of yield measurement.

[0054] Figure 3 A flow chart for obtaining dry weight data of crops provided in an embodiment of the present application.

[0055] S301. When the harvester meets the crop yield monitoring conditions, a humidity signal from a moisture sensor is received.

[0056] Here, the moisture sensor is a device that can detect and measure the moisture content in a substance. The moisture sensor is set below the grain conveyor auger and is used to detect the moisture content of the crops that are transported from the grain elevator to the grain conveyor auger and finally fall into the granary. This helps to understand the moisture status of the crops, which is crucial for subsequent yield calculations and crop processing. The grain conveyor auger is used to transport the crops received from the grain elevator to the granary. The humidity signal is the output of the moisture sensor, which is used to indicate the moisture content of the crops.

[0057] S302: Calculate the moisture content of the crop according to the humidity signal.

[0058] Here, moisture content refers to the percentage of water in the crop, which is calculated by processing the humidity signal. Moisture content is very important for understanding the dryness of the crop and calculating the dry weight data.

[0059] S303. Obtain dry weight data of the crop according to the moisture content and the second yield data.

[0060] Here, dry weight data is obtained by converting the actual weight of the crop (taking into account the moisture content) into the weight of the crop containing standard moisture.

[0061] S304, displaying the moisture content and dry weight data on the vehicle-mounted display terminal, and uploading the moisture content and dry weight data to the cloud platform.

[0062] In a preferred example of the present application, it also includes: calculating the per-acre yield data of the crop based on the harvester's speed, operation time and second yield data, generating a crop yield map based on the harvester's location information and the per-acre yield data, and synchronously displaying the yield map on the vehicle-mounted display terminal and the cloud platform.

[0063] The per-acre yield data is calculated by combining the harvester's speed, operating time and second yield data. It reflects the yield of crops per unit area and is an important indicator for evaluating crop yield and agricultural production efficiency. The yield map is generated by combining the harvester's location information, per-acre yield data and delay time. The delay time refers to the interval from the crop entering the harvester to the crop grain hitting the impulse sensor. The on-board display terminal generates a crop yield map and moisture map based on the harvester's location information, per-acre yield data and delay time, which is used for the precise correspondence between per-acre yield data and location information. It intuitively shows the yield distribution of crops in different geographical locations. This map helps agricultural managers understand the yield distribution and changing trends of crops and provides a basis for agricultural production decisions.
