Description

Technical Field

[0001] This invention relates to the field of agricultural intelligent equipment technology, specifically to an E2400 electric-driven precision seeding operation monitoring terminal, which is suitable for agricultural scenarios such as large-scale planting, fragmented plot operations, and multi-crop cultivation, and can realize precise, intelligent and efficient control of seeding and fertilization operations. Background Technology

[0002] In current agricultural sowing and fertilization operations, traditional technologies rely on mechanical transmission, depending on the rotation of ground wheels to obtain speed signals, and using chains and gears to drive the seed metering and fertilizer metering devices. This requires manual monitoring of the operation. This approach suffers from several unresolved problems: Low speed measurement accuracy: The ground wheel is easily affected by mud and weeds in the field and slips, which leads to distortion of the vehicle speed signal, causing deviation in plant spacing and making it difficult to guarantee the sowing density; High maintenance costs: The mechanical transmission structure is complex, the parts are prone to wear and corrosion, and failures occur frequently, requiring frequent shutdowns for maintenance, which affects work efficiency; Lagging monitoring: The lack of a real-time monitoring mechanism means that problems such as missed sowing, double sowing, and fertilizer loss can only be discovered afterward, resulting in a large waste of seeds and fertilizers; Poor adaptability: It cannot flexibly cope with irregular plots, and whole-row operation is prone to edge omissions or reseeding, resulting in low land utilization; Initial operation defects: the mechanical transmission "does not sow when it is not moving", there is no sowing distance in the initial operation stage, and the sowing in the starting area of ​​the field is incomplete; Insufficient intelligence: It is difficult to adapt to the agronomic requirements of multiple crops, the operation data is stored in a scattered manner, and there is a lack of centralized management and traceability channels, which is not conducive to large-scale management and control.

[0003] Existing technologies cannot simultaneously address multiple requirements such as speed measurement accuracy, structural reliability, real-time monitoring, plot adaptability, and intelligent data management, thus hindering the improvement of efficiency and quality in agricultural sowing operations.

[0004] Therefore, those skilled in the art provide an E2400 electrically driven precision seeding operation monitoring terminal to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an E2400 electrically driven precision seeding operation monitoring terminal, which solves the problem that existing technologies cannot simultaneously meet multiple requirements such as speed measurement accuracy, structural reliability, real-time monitoring, plot adaptability, and intelligent data management, thus hindering the improvement of efficiency and quality in agricultural seeding operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An E2400 electrically driven precision seeding operation monitoring terminal includes a sensing layer, a control layer, an execution layer, a display and interaction layer, and a cloud platform layer.

[0011] Furthermore, the one-click seed preparation function can automatically drive the seeding motor to rotate and complete the seeding tray filling after the seeding fan generates normal negative pressure, so that the initial seeding can be achieved without moving the equipment.

[0012] Furthermore, the cloud platform layer supports access for single or multiple devices, and uploads data such as operating area, seeding amount, plant spacing qualification rate, and sensor status at a set frequency (default 5 minutes / time). It supports querying via computer webpage and mobile APP, and has access control and data traceability functions.

This terminal adopts a five-layer architecture design, with each layer's functions working in tandem to achieve a complete closed loop of "speed measurement-control-execution-monitoring-data management". The specific structure and functions are as follows: Perception layer: Data acquisition through multi-source sensors Dual speed measurement sources: the Beidou satellite positioning speed measurement unit (external antenna and signal amplification module) acquires centimeter-level positioning data and vehicle speed, while the millimeter-wave speed measurement radar independently collects vehicle speed. The two data are fused and noise reduced, and a ground wheel speed measurement interface is reserved to support redundancy of three speed measurement sources. Status sensors and negative pressure sensors monitor the wind pressure of the seeding fan, position sensors detect the lifting and lowering status of the seeder, seed sensing gratings accurately count the number of seeds falling, and fertilizer probes monitor the amount of fertilizer applied and fertilizer pipe blockage.

[0024] Control Layer: Core Control and Computing Center The microcomputer data processor receives signals from the sensing layer and, in conjunction with user-defined parameters such as the number of holes in the seed tray, plant spacing, and operating width, calculates the rotation speed and start / stop commands of the seeding motor and fertilizer motor using a built-in algorithm. The integrated fault diagnosis module can identify faults such as missed broadcasts, replays, pipe blockages, and abnormal air pressure in real time, trigger alarm logic, and record fault information. It has a built-in wireless communication module that synchronizes data to the cloud platform at a set frequency, supporting real-time uploading of data from key nodes.

[0025] Execution layer: Electric drive actuator The electric drive system features a high-speed, high-precision motor with a maximum torque of 3.5 N·m and a maximum power of 60 W. It also includes overload protection and can drive the 24 rows of seeding units and fertilizer boxes independently or centrally. The seeding tray is compatible with different crop seeds and supports seed filling function; The fertilizer box design features a "one motor drives one fertilizer box" system for oral fertilizers, enabling precise control, while a "one motor drives multiple fertilizer boxes" system for basal fertilizers, balancing efficiency and cost.

[0026] Display Interaction Layer: Human-Computer Interaction Interface A high-definition touch screen with a fully Chinese interface displays real-time data such as vehicle speed, plant spacing, operating area, seeding rate, and equipment status. It supports parameter settings (such as the number of holes in the seed tray, plant spacing, alarm threshold, etc.), viewing fault logs, and quick operations (such as one-click seed backup, single-row start / stop, and simulation operation).

[0027] Cloud platform layer: IoT data management system Functional modules include: device management, data storage, data visualization, query and statistics, and access control. Data synchronization automatically uploads key data such as operating area, seeding amount, plant spacing qualification rate, and fault records; Access methods include desktop webpage and mobile APP, supporting single-device trajectory query and multi-device data aggregation.

[0028] The key functionalities are implemented as follows: Key Functionality Implementation Precision seeding control: Based on the algorithm of "vehicle speed-plant spacing-number of seed tray holes", the rotation speed of the electric drive system is controlled to achieve fixed-distance seeding with a plant spacing deviation of ≤±3%; Independent start / stop for a single row: Users activate the target seeding row based on the shape of the plot and close redundant rows at the edges to avoid missed seeding / re-seeding; One-click seed preparation: The system automatically drives the seeding motor to rotate and fill the seed box, allowing for initial seed placement without the need for moving any equipment; Dual plant spacing switching: adapts to different crop planting densities, and users can switch between them with one click on the display screen; Independent fertilization control: The electric drive systems for primordial fertilizer and basal fertilizer work independently, with real-time monitoring of fertilizer application and support for blockage alarms; Simulated operation: Set the simulated vehicle speed, test the motor rotation direction and start / stop status, and complete the debugging before going on the ground; Intelligent alarm: The system triggers an audible and visual alarm when there is a missed broadcast / replay, fertilizer leakage, fertilizer pipe blockage, or abnormal air pressure, and records the location and time of the fault.

[0030] ②Work Process Preparation stage: After powering on, the terminal automatically connects to the cloud platform and reads historical parameters; starts simulation operation, sets the simulation speed to 5km / h, tests that the motor is running normally, activates the one-click seed preparation function, and completes seed filling of the seed tray; Operation phase: The equipment enters the cornfield, and the Beidou and millimeter-wave radar synchronously measure the speed. The real-time vehicle speed is 8km / h. The control layer calculates the electric drive speed and drives the sowing and fertilization actuators. The sensing layer monitors the number of seeds, fertilization status and wind pressure in real time. The normal wind pressure range is 0.3-0.5MPa. Handling irregular plots: In the corner areas of the plot, users can turn off 6 rows of edge planting units on the display screen and only activate 18 rows of core areas to avoid replanting; Data synchronization: Data is uploaded every 5 minutes during operation, including operation area, sowing amount, and plant spacing qualification rate. When a fertilizer pipe blockage occurs, an audible and visual alarm is triggered immediately and fault information is uploaded. When the task is completed: the terminal automatically summarizes the data, generates a task report, and synchronizes the data to the cloud platform. Implementation effect

[0033] ②Work Process Adapted to different plots: For each irregularly shaped field, the number of active rows can be flexibly adjusted from 8 to 16 through the independent start / stop function of a single row to avoid missing the edge planting; Speed ​​measurement and control: Beidou and millimeter-wave radar complement each other for speed measurement, eliminating the risk of wheel slippage caused by weeds in the field, and stabilizing the vehicle speed at 6km / h; Data Management: After the operation is completed, the cloud platform automatically summarizes the operation data of the five plots and generates a summary report. Implementation effect
