Description

Technical Field

[0001] This invention relates to the field of agricultural intelligent equipment technology, specifically a Beidou-based V1200 electric-driven precision seeding operation monitoring terminal platform, which is suitable for large-scale or fragmented plot seeding operations of small and medium-sized growers and agricultural cooperatives. It can realize precision seeding, real-time monitoring and intelligent data management of various crops such as corn, soybeans, rapeseed and vegetables. Background Technology

[0002] In current agricultural sowing operations, traditional techniques rely on ground-wheel transmission as the core, using a mechanical structure to drive the seed metering device, coupled with a simple monitoring device. During operation, manual observation of the sowing status is required, and adjustments must be made manually after problems such as missed sowing are detected. This approach has several unresolved drawbacks: 1. Low speed measurement accuracy: The ground wheel is easily affected by mud and weeds in the field and slips, which leads to the distortion of the speed signal, causing deviation in plant spacing and making it difficult to guarantee the sowing density; 2. High maintenance costs: Mechanical transmission systems (chains, gears, etc.) have complex structures, and their parts are prone to wear and corrosion, resulting in frequent failures and requiring frequent downtime for maintenance; 3. Lagging monitoring: The lack of real-time and accurate seed landing monitoring and intelligent alarm mechanism means that problems such as missed sowing and reseeding need to be discovered afterward, resulting in a large amount of seed waste; 4. Inconvenient data management: Operational data relies on local recording or manual statistics, with no remote management channels, making centralized storage and traceability analysis impossible, which is not conducive to the optimization of agronomic parameters; 5. Limited adaptability: It is difficult to flexibly meet the sowing needs of different crops and different agronomic scenarios, and its versatility is poor; 6. Imbalance between cost and performance: Existing intelligent seeding equipment is mostly equipped with redundant components such as millimeter-wave radar, which is costly and difficult to meet the cost-effectiveness requirements of small and medium-sized growers.

[0003] Existing technologies cannot simultaneously address the core requirements of "accuracy assurance, cost control, ease of operation, and adaptability to multiple scenarios," which restricts the widespread application of economical intelligent seeding equipment.

[0004] Therefore, those skilled in the art have provided a BeiDou-based V1200 electric-driven precision seeding operation monitoring terminal platform to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a BeiDou-based V1200 electric-driven precision seeding operation monitoring terminal platform, which solves the problem that existing technologies cannot simultaneously meet the core requirements of "accuracy assurance, cost control, ease of operation, and multi-scenario adaptability," thus hindering the widespread application of economical intelligent seeding equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A Beidou-based V1200 electric-driven precision seeding operation monitoring terminal platform includes a sensing layer, a control layer, an execution layer, a display and interaction layer, and a cloud platform layer. Each layer works together to realize the speed measurement, control, monitoring, and data management of precision seeding operations. The specific structure and core process are as follows: Sensing layer: Includes Beidou satellite positioning speed measurement unit, photoelectric element sensor, and reserved wheel speed sensor interface for collecting real-time vehicle speed and seed landing status data; Control layer: This is a microcomputer data processor that receives data from the sensing layer, calculates the seeding motor drive command based on user-defined parameters, and performs fault diagnosis and alarm logic operations. Execution layer: includes electric drive system and seeding tray. The electric drive system drives the seeding tray to rotate precisely, and the seeding tray is adapted to different crop seeds. Display and interaction layer: Equipped with a button-type display screen, supporting parameter setting, real-time data display, fault alarm and equipment debugging; Cloud platform layer: This is an IoT cloud data management platform that enables wireless transmission, centralized storage, querying, and statistics of operational data. Core process: Beidou speed measurement → parameter matching → electric drive control for seeding → photoelectric monitoring of seed placement → fault alarm → cloud data synchronization, supporting independent control and monitoring of up to 48 rows of seeding units.

[0007] Furthermore, the BeiDou satellite positioning and speed measurement unit supports centimeter-level positioning with a speed measurement error of ≤±0.1km / h. It features an external antenna and signal amplification module, and eliminates environmental interference through location information noise reduction calculations, replacing traditional ground wheel transmission and millimeter-wave radar to reduce hardware costs.

[0008] Furthermore, the photoelectric element sensor is fixed below the seed distributor of each seed metering component, with a seed drop recognition accuracy of ≥99%, and can capture missed seeding and reseeding status in real time, supporting independent monitoring and alarm of 48 rows of seeding units.

[0009] Furthermore, the display interaction layer supports multiple parameter programming settings: working width 1.00-9.90 meters (step size 0.01 meters), area counting constant 20-999 (step size 1), alarm interval 0-5 seconds (step size 1 second), and sowing sensitivity 1-28 levels (levels 1-12 are normal mode, levels 21-28 are rapeseed mode).

[0010] Furthermore, the fault alarm mechanism is as follows: when the seeding state exceeds the programmed tolerance, a red visual alarm is first triggered on the corresponding row of the display screen, and an audible alarm is activated after the set alarm interval is reached. At the same time, the fault time and location are recorded, and fault log queries are supported.

[0011] Furthermore, the cloud platform layer supports access for single or multiple devices, and uploads data on operating area, plant spacing qualification rate, seeding amount, and sensor status at a default frequency of 5 minutes per upload. It supports web page queries on computers and mobile devices, has data traceability and export functions, and reserves interfaces for integration with agricultural management systems.

[0012] Furthermore, the electric drive system of the execution layer adopts a high-reliability motor, which is suitable for economical needs and extends the maintenance cycle by 50% compared with traditional mechanical transmission. The overall protection level of the equipment reaches IP65, the protection level of photoelectric components, sensors and connectors reaches IP67, it supports 13Vdc±3Vdc power supply and is equipped with a self-resetting safety fuse.

[0013] Furthermore, the terminal platform supports the sowing of various crops such as corn, soybeans, rapeseed, and vegetables. By switching the sowing sensitivity level, it can adapt to seeds of different particle sizes and, with the help of replaceable sowing trays, meet the needs of different agronomic scenarios.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-4 As shown, this embodiment of the invention provides a BeiDou-based V1200 electric-driven precision seeding operation monitoring terminal platform. The terminal platform adopts a five-layer architecture, with each layer working together to achieve a complete closed loop of "speed measurement-control-execution-monitoring-data management," specifically: Perception Layer: Core Data Acquisition Module Beidou satellite positioning speed measurement unit: integrated into the control layer box, with an external antenna and signal amplification module, it receives satellite signals and outputs real-time vehicle speed (error ≤ ±0.1km / h) and location data. It eliminates environmental interference through noise reduction calculations, replacing traditional ground wheel speed measurement. Photoelectric element sensor: Fixed below the seed distributor of each seeding component, it detects the seed landing status in real time and outputs a switch signal; Reserved interface: Supports connection to ground wheel speed sensor as an auxiliary speed measurement supplement to improve scene adaptability.

[0024] Control Layer: Core Computing and Control Center Microcomputer data processor: Receives vehicle speed and seed dropping signals from the sensing layer, and combines them with user-set parameters such as working width, number of seed tray holes, and sensitivity. It then calculates the sowing motor speed command using the built-in algorithm of "vehicle speed - plant spacing - number of seed tray holes". Fault diagnosis module: Real-time identification of problems such as seed dropping abnormalities, sensor failures, and short circuits, triggering alarm logic and recording fault information.

[0025] Execution layer: Electric drive execution module Electric drive system: Adopts a high-reliability motor, adapted to economic needs, with a maximum torque ≥2.5N・m, power ≥40W, built-in overload protection, and drives the seeding tray to rotate precisely; Seeding tray: The interchangeable design is compatible with different crop seeds such as corn, soybeans, rapeseed, and vegetables, ensuring smooth seeding.

[0026] Display Interaction Layer: Human-Computer Interaction Module Button-operated display screen: intuitively displays data such as real-time vehicle speed, working area, partial area, and sensor status; Function entry: Supports parameter settings (job width, sensitivity, etc.), fault log viewing, counter zeroing, simulation operation debugging, etc. The interface is simple and easy to understand.

[0027] Cloud platform layer: Data management module Core functions: device management, data storage, data visualization, query and statistics; Data synchronization: Data such as operating area, plant spacing qualification rate, sowing amount, and fault records are uploaded at a default frequency of 5 minutes / time. When a fault occurs, the data is automatically uploaded in real time. Access methods: Log in and query via computer webpage or mobile webpage, supporting searches by device number, operation time, and plot location.

[0028] The following key functions can be achieved through this seeding operation monitoring terminal platform: Precision seeding control: The Beidou speed measurement unit collects real-time vehicle speed, the processor calculates the motor speed, drives the seeding tray to drop seeds at a fixed distance, and the seeding is monitored by photoelectric sensors to form a closed-loop control, with a plant spacing deviation of ≤±3%; Parameter programming and calibration: The working width is programmed after being calculated by "row spacing × number of rows" (1.00-9.90 meters). The area counting supports manual input of constants or automatic calibration (records the number of pulses every 100 meters traveled). The alarm interval is adjustable from 0 to 5 seconds. Real-time alarm mechanism: When seeding is abnormal, the corresponding row's red visual alarm is triggered first, and the audible alarm is activated after the set interval is reached, while the fault information is recorded; sensor failure or circuit short circuit will trigger an immediate alarm. Simulated operation and debugging: No need to go on the ground, test the motor's rotation direction and start / stop status by setting a simulated vehicle speed, reducing trial and error costs; Multi-crop adaptation: By switching between 1-28 levels of seeding sensitivity and using a replaceable seeding tray, it can adapt to crops such as corn (sensitivity level 5-8), soybean (sensitivity level 3-6), rapeseed (sensitivity level 23-26), and vegetables (sensitivity level 10-12); Data traceability management: The cloud platform stores data throughout the entire operation process, supports historical data query, statistical analysis and export, and provides data support for the optimization of agronomic parameters.

[0030] ②Work Process Preparation phase: After powering on, the terminal will automatically complete a 2-second self-test, displaying the cumulative operation hours through a fully lit screen and sound prompts; set the above parameters via buttons and enable the cloud synchronization function; install the corn adapter seeding tray and connect it to a 13Vdc power supply.

[0031] Operation phase: When the equipment enters the plot, the Beidou speed measurement unit collects the vehicle speed in real time, such as 8km / h. The processor calculates the speed of the electric drive motor and drives the seeding tray to drop the seeds at a fixed distance. The photoelectric sensor monitors the seeding status of each row simultaneously. When there is no abnormality, the display screen shows a normal green indicator.

[0032] Anomaly Handling: When a line is missed, the corresponding line marker immediately turns red, and a "beep" audible alarm is activated after 1 second. At the same time, the location and time of the missed broadcast are recorded. The user stops the machine to check the seed metering device, and the alarm automatically clears after the fault is resolved.

[0033] Data synchronization: Data is uploaded every 5 minutes during the operation, including the operation area and the qualified rate of plant spacing (up to 98.5%). After the operation is completed, the terminal automatically summarizes the data, and the cloud platform generates an operation report, such as the operation area of ​​50 mu, the sowing amount of 15 kg, and the seed saving rate of 10%. Implementation effect

Implementation effect

[0037] Compatibility: Precisely compatible with small-diameter rapeseed seeds, with a seed distribution uniformity of ≥95%; Efficiency: 8 acres can be completed in 3 hours, which is 5 times faster than manual sowing; Cost: The equipment purchase cost is 32% lower than similar equipment with millimeter-wave radar, and there are no additional maintenance costs.
