[0002] Soil sampling is a fundamental work in agricultural and environmental monitoring, which is of great significance for precision fertilization, soil quality assessment and pollution control. Traditional sampling mainly relies on manual operation, which is low in efficiency and poor in consistency. To improve the standardization and automation level of sampling, vehicle-mounted soil sampling equipment has emerged as the times require. This system integrates mechanical soil sampling, positioning measurement and data acquisition functions, and can realize rapid, continuous and fixed-point sampling, and is widely used in large-scale farmland investigation, geological exploration and ecological research fields.

[0003] However, the existing vehicle-mounted soil sampling equipment still has obvious limitations. First, the automation degree of the equipment is limited, and many operations still need manual intervention, such as depth control, sample marking, etc., which not only is cumbersome, but also is prone to human error. Second, the data recording method mainly depends on manual input or scattered storage, and lacks unified information management, which is easy to cause data loss or confusion, and is difficult to meet the requirements of modern monitoring on data traceability. More importantly, the existing equipment usually lacks real-time data uploading and remote interaction capability, and the sampling information cannot be synchronized to the cloud platform in time, which limits the data on-site verification and remote collaborative analysis capability. In addition, the reliability of the equipment in complex environment is insufficient, such as poor dustproof, waterproof and shock resistance, which also affects its stability in long-term use in the field.

Shielded cables and waterproof connectors are used to connect between modules, to improve system stability and outdoor operation reliability.

[0034] In some embodiments of the application, the cloud platform can deploy a data management server, for storing sampling data and providing data visualization and analysis functions, such as generating a land distribution map or a parameter change curve, to facilitate later soil quality evaluation and agricultural decision-making.

[0035] In summary, the vehicle-mounted soil sampling data acquisition control system provided by the application contains a system control box, a positioning and sensing module, a sampling execution module, and a data management and communication module, and the integrated design avoids the dispersion and independence of each function; the system control box is built-in with a multifunctional data interface backboard, the positioning and sensing module and the sampling execution module are connected to the backboard and transmit soil sample data including sampling point position data, soil parameters, soil sampling depth data, and compactness data, realizing centralized reception and unified transmission of multiple types of soil sample data, and ensuring the integrity and consistency of data acquisition; the data management and communication module contains a sample identification unit, a vehicle-mounted computing unit, and a wireless communication unit, realizing the collaborative integration of soil sample identification, data processing, and remote transmission functions; the sample identification unit is connected to the vehicle-mounted computing unit through a USB interface, generates a unique soil sample number, and controls the printing of a soil sample label containing the number, establishing a direct association between physical soil samples and digital information; the vehicle-mounted computing unit is connected to the system control box through a USB or network interface, receives soil sample data and binds it with the unique soil sample number, ensuring the traceability of the data; the wireless communication unit is connected to the vehicle-mounted computing unit through an Ethernet interface, receives the bound data and uploads it to a cloud platform, realizing remote storage and sharing of soil sample data, and facilitating centralized management and subsequent analysis of data.

[0036] Through integrated design of the system control box, the positioning and sensing module, the sampling execution module, and the data management and communication module, integrated operation of sampling, detection, identification, and data uploading functions is realized, improving the automation level and data consistency of vehicle-mounted sampling operations.

[0037] In some embodiments of the application, as shown in Figure 1 The system control box 100 is also built-in with a power distribution board 103 and a relay array 102; The power distribution board 103 is connected to an external power module 500 at the input end and connected to the positioning and sensing module 200, the sampling execution module 300, and the data management and communication module 400 at the output end, for distributing power to each module; The relay array 102 is connected to the main controller of the system control box 100 at the input end and connected to the sampling execution module 300 at the output end, for receiving control signals forwarded by the main controller and controlling the start and stop of the sampling execution module 300.

[0038] It should be noted that the main controller can be an STM32 or an embedded processor with equivalent performance, for collecting and distributing the working state signals of each module, ensuring the timing consistency of instruction execution.

[0039] In some embodiments of the present application, the external power module is a generator, the power input port of the generator is an alternating current power supply of 220 volts, and the generator is provided with an overload protection circuit, which automatically cuts off the output when the current exceeds 30A, preventing damage to the equipment.

[0040] In some embodiments of the present application, the system control box is provided with overvoltage, overcurrent and temperature protection circuits to prevent damage to components due to power fluctuations during long-term outdoor operation.

[0041] Through the unified design of the multifunctional data interface backplane, centralized access and synchronous transmission of data of various types of sensors are realized, thereby avoiding signal interference in the multi-channel acquisition process and improving the stability and transmission efficiency of data acquisition.

[0042] In some embodiments of the present application, the multifunctional data interface backplane is integrated with a CAN bus interface, an RS485 interface, an analog interface and a USB or network interface. As shown in Figure 1 The positioning and sensing module 200 includes a GPS positioning unit 201 and a soil multi-in-one sensing unit 202. The GPS positioning unit 201 is connected to the multifunctional data interface backplane 102 of the system control box 100 through the CAN bus interface, for real-time collection of position data of the sampling point and transmission to the system control box; the position data includes longitude, latitude and elevation data. The soil multi-in-one sensing unit 202 is connected to the multifunctional data interface backplane 102 through the RS485 interface, for detection of soil parameters and transmission to the system control box 100; the soil parameters include pH value, temperature and humidity, and nitrogen, phosphorus and potassium content. The collected position data and soil parameters are synchronously forwarded to the vehicle-mounted computing unit 402 through the system control box 100 and a corresponding relationship between the position data and the soil parameters is formed.

[0043] It should be noted that the GPS positioning unit can be a positioning module supporting RTK real-time difference to improve the positioning accuracy to centimeter level, meeting the demand for accurate positioning of the sampling point.

[0044] In some embodiments of the present application, the GPS positioning unit has an accuracy of ±0.1m and uploads the position data of the sampling point once per second.

[0045] In some embodiments of the present invention, the soil all-in-one sensing unit can also be expanded to detect parameters such as electrical conductivity and organic matter content, so as to conduct a more comprehensive evaluation of soil fertility; the soil all-in-one sensing unit can analyze the pH value (range 3-10), temperature (-20℃~60℃), humidity (0-100%) and nitrogen, phosphorus and potassium content of soil samples in real time (the detection range is determined by the sensor range, unit mg / kg), and the software automatically filters out abnormal values ​​(such as discarding when humidity >100%).

[0046] The power distribution board independently allocates power to each module, ensuring the stability of power supply during system operation; the relay array receives control signals forwarded by the main controller, enabling precise control and safe start-stop of the sampling execution module.

[0047] In some embodiments of the present invention, such as Figure 1 As shown, the sampling execution module 300 includes an electric soil sampling mechanism 301 and a soil compaction detection unit 302. The power supply terminal of the sampling execution module 300 is connected to the power distribution board 103 through a relay array 102. The electric soil sampling mechanism includes a multi-stage telescopic lifting rod, a soil sampling drill bit, and a depth sensor. The control terminal is connected to the system control box through an opto-isolated I / O interface. It is used to receive control signals from the on-board computing unit forwarded by the system control box and to perform soil sampling. The depth sensor transmits the soil sampling depth data to the system control box through a signal line. The soil compaction detection unit 302 includes a conical compaction head and a resistance sensor. The data terminal is connected to the multi-functional data interface backplane through an analog interface. It is used to detect the soil resistance value after soil sampling and transmit it to the system control box 100. The resistance value is used to derive the soil compaction data.

[0048] It should be noted that the multi-stage telescopic lifting rod can achieve segmented extension and retraction via a screw motor drive, thereby improving the accuracy of sampling depth control. The drill bit can adopt a detachable structure, making it easy to replace different specifications of drill bits according to different soil textures.

[0049] It should be noted that the compaction degree and resistance values ​​are stored in CSV format, with timestamps accurate to milliseconds.

[0050] In some embodiments of the present invention, the soil sampling depth of the multi-stage telescopic lifting rod can be preset to different levels such as 20cm, 40cm or 60cm, and can be automatically adjusted through software configuration; the multi-stage telescopic lifting rod has a stroke of 1.5m and a thrust of 500kg, and a detachable sampling drill bit (50mm in diameter) is installed at the lower end of its piston rod. The drill bit is made of cemented carbide and has a wear resistance life of up to 1000 sampling cycles.

[0051] In some embodiments of the present invention, the soil compaction detection unit (range 0-200kPa) receives commands through the relay array of the control box, and the compaction head adopts a conical design (bottom area 20cm²) to ensure data consistency.

[0052] By acquiring real-time latitude, longitude, and elevation data of sampling points through GPS positioning units, and combining this with pH value, temperature, humidity, and nitrogen, phosphorus, and potassium content detected by the soil multi-sensor unit, the spatial location of sampling points and soil physicochemical parameters are automatically correlated and bound, thereby ensuring the spatial accuracy and traceability of the data.

[0053] In some embodiments of the present invention, the sample identification unit includes an RFID reader and a thermal printer, and the sample identification unit is connected to the vehicle-mounted computing unit via a USB interface. The RFID reader receives the trigger signal from the vehicle-mounted computing unit, generates a unique soil sample number, and returns the unique soil sample number to the vehicle-mounted computing unit. The unique soil sample number is generated by combining the sampling date, task number, and sampling sequence number according to a preset format. The thermal printer receives printing instructions from the on-board computing unit, prints labels containing unique soil sample numbers, and affixes them to the corresponding soil sample bags to associate physical soil samples with numerical numbers.

[0054] It should be noted that the RFID tag can be a passive high-frequency tag. The printed tag contains both a QR code and RFID chip information, which facilitates both manual and electronic identification.

[0055] Automatic sampling is achieved through an electric soil sampling mechanism, with a depth sensor providing feedback on the soil sampling depth to ensure accurate and controllable sampling depth. Combined with resistance data collected by the compaction testing unit, soil sampling and compaction testing are synchronized, improving sampling efficiency and data integrity.

[0056] In some embodiments of the present invention, the soil sampling depth range is 0-2m with an accuracy of ±1cm; the soil compaction measurement range derived from resistance data is 0-50cm with an accuracy of ±0.5cm.

[0057] In some embodiments of the present invention, the vehicle-mounted computing unit is equipped with data processing software. The software is used to receive soil sample data forwarded by the system control box and soil sample unique number transmitted by the sample identification unit. After binding the soil sample data and soil sample unique number according to preset rules, a structured soil sample dataset with timestamp is generated and stored. The soil sample dataset is then output to the wireless communication unit.

[0058] It should be noted that the vehicle-mounted computing unit adopts an industrial-grade ruggedized computer, possessing dustproof, waterproof, and shockproof capabilities. It is suitable for complex environments such as vehicle vibration and field sampling, ensuring stable system operation and continuous data processing under harsh conditions. The data processing software can adopt a modular design, including functional modules such as task management, equipment status monitoring, and data visualization, and supports a touchscreen interface.

[0059] The data logging software (developed based on Winform) installed in the vehicle's "three-proof computer" can achieve fully automated control of the entire process.

[0060] In some embodiments of the present invention, software initialization and configuration require the user to input task parameters after starting the software, including the sampling location (i.e., GPS coordinates of the sampling area, longitude and latitude), the sampling depth range (default 0-1m), and sensor calibration coefficients (such as pH offset value). The software automatically generates a task ID and links it with the RFID module to assign a unique number to each soil sample. The signal is set so that the software detects the wireless DTU connection status through a virtual serial port, triggering an alarm when the signal strength is below -80dBm.

[0061] In some embodiments of the present invention, the software-embedded algorithm can dynamically adjust the sampling point density (e.g., add one point every 10m²) based on positioning data and compaction changes. The data is stored locally on an SSD hard drive and simultaneously uploaded to a cloud platform via a wireless communication unit, supporting JSON or MQTT protocols, with the upload interval set to 1s or 5s.

[0062] A unique soil sample number containing the sampling date, task number, and sequence number is generated by an RFID reader, and a label is printed by a thermal printer. This achieves a one-to-one correspondence between the physical sample and the digital number, thereby improving the standardization of sample management and the reliability of subsequent traceability.

[0063] In some embodiments of the present invention, the wireless communication unit is a dual-link data transmission module that supports Wi-Fi and 4G / 5G, and is connected to the vehicle-mounted computing unit through an Ethernet interface to receive the structured soil sample dataset output by the vehicle-mounted computing unit. The wireless communication unit uploads the dataset to the cloud platform via the Wi-Fi link at preset intervals by default. When the Wi-Fi signal strength is detected to be lower than the preset threshold, it automatically switches to the 4G / 5G link to continue uploading.

[0064] It should be noted that if the network signal is interrupted on site, the communication module will automatically cache the unuploaded data and continue uploading it after the signal is restored.

[0065] In some embodiments of the present invention, the preset upload interval can be set to 30 seconds to 5 minutes depending on the sampling task volume; when the Wi-Fi signal strength is detected to be lower than the preset threshold of -80dBm, the connection is automatically switched to 4G / 5G link to continue uploading.

[0066] By using the onboard computing unit to uniformly bind and structure the collected data, the automatic integration and formatted management of the sampled data is realized, providing a unified data source for subsequent cloud uploads and data analysis.

[0067] In some embodiments of the present invention, a ship-shaped control switch and a display are externally mounted on the system control box; The ship-shaped control switch is electrically connected to the main controller and is used to receive start and stop commands input manually and control the on / off state of the sampling execution module and each functional module. The display is connected to the vehicle-mounted computing unit via a signal cable to display the sampling task number, sampling point location, soil parameters, soil sampling depth, and system operating status information in real time.

[0068] It should be noted that the display can be a 7-inch touchscreen, used to show the sampling task progress and the status of each module, and supports manual adjustment of sampling depth or task order.

[0069] In some embodiments of the present invention, the rated current of the boat-shaped control switch is 10A, and the number can be 5, of which 3 are used to control the lifting and rotation functions of the electric lifting soil sampling rod, 1 controls the working mode of the soil compactor (such as continuous compaction or point compaction), and 1 is a spare switch.

[0070] The wireless communication unit uses a dual-link upload mechanism of Wi-Fi and 4G / 5G to ensure stable data transmission in different network environments, thereby improving the real-time performance and transmission reliability of data in field operation scenarios.

[0071] In some embodiments of the present invention, such as Figure 2 As shown, the control system of the vehicle-mounted soil sampling data acquisition equipment includes: a system control box 100; a movable fixing plate 1, a bracket 2, a first telescopic lifting rod 3, a second telescopic lifting rod 4, the first telescopic lifting rod 3 and the second telescopic lifting rod 4 forming a first-level lifting rod; a third telescopic lifting rod 5 and a fourth telescopic lifting rod 6, the third telescopic lifting rod 5 and the fourth telescopic lifting rod 6 forming a second-level lifting rod; a compaction degree detection unit lifting rod 7, a soil sampling depth sensor 8; a compaction depth sensor 9, which is matched with the soil compaction degree detection unit; a rotary motor fixing plate 10, a soil multi-functional sensor 11; a first slide 12, a second slide 13, a soil sampling rod 14, the soil sampling rod 14 being matched with a soil sampling drill bit; a rotary motor 15, which drives the soil sampling drill bit; and a soil compactor 16, including a conical compaction head and a resistance sensor.

Figure 3 As shown, this embodiment of the invention also provides a vehicle-mounted soil sampling data acquisition and control method, including: S301. Power on, start the system through the on-board computing unit and load the preset sampling task parameters to complete system preparation; S302. Collect real-time vehicle location data through the GPS positioning unit and transmit it to the on-board computing unit; use the on-board computing unit to call the preset sampling point grid parameters to determine the target sampling point and generate a sampling path; drive the vehicle to the target sampling point along the sampling path; S303: Send a soil sampling command to the system control box, control the multi-stage telescopic lifting rod to extend to a preset depth and the soil sampling drill bit to rotate and sample soil; collect soil sampling depth data through the depth sensor and transmit it to the system control box; after soil sampling is completed, control the multi-stage telescopic lifting rod to retract and the drill bit to discharge the soil sample into the sample bag; detect soil parameters through the soil multi-in-one sensor unit and transmit them to the system control box; at the same time, press down through the conical compaction head of the soil compaction detection unit, detect the soil resistance value through the resistance sensor and transmit it to the system control box; S304.

S305: Receives structured datasets via wireless communication unit and uploads them to cloud platform via Wi-Fi link at preset time intervals; when the Wi-Fi signal strength is detected to be lower than a preset threshold, automatically switches to 4G / 5G link to continue uploading, completing a single sampling.

[0073] It should be noted that, in practice, the on-board computing unit can automatically determine whether all sampling points have been collected based on the sampling task number, and generate a sampling report file after the task is completed, which includes the geographical location, parameter records and time information of each sampling point.

[0074] In some embodiments of the present invention, a device self-test is required before sampling. After starting the gasoline generator, the control box performs a power supply test (voltage 220V±10%), and the LED display lights up green to indicate normal operation. The GPS, wireless DTU, and sensor switches are turned on in sequence, and the software displays a "ready" status.

[0075] In some embodiments of the present invention, before sampling, the vehicle travels to the starting point of the sampling area, and the GPS obtains the reference coordinates (such as longitude 112.5°E, latitude 30.2°N). The software automatically plans the grid path (grid size 5m×5m).

[0076] In some embodiments of the present invention, the electric lifting soil sampling rod is started by pressing the control box switch, the piston rod descends to a set depth (e.g., 0.5m), and the sampling drill bit rotates to cut into the soil (rotation speed 30rpm).

[0077] In some embodiments of the present invention, the soil compaction detection unit is activated, the compaction head is pressed down to the soil surface, and the software records the resistance peak and displays it on the LED screen.

[0078] In some embodiments of the present invention, the RFID module automatically writes the soil sample number (e.g., "SAM-202405001") to the label, and the software controls a small thermal printer to print the label (50mm × 30mm) and affix it to the sample bag. The operator scans the label with a barcode scanner, and the software confirms the data entry.

[0079] In some embodiments of the present invention, after sampling is completed, the software automatically packages the data (including GPS trajectory, sensor readings and soil sample number) and uploads it to the cloud via a 5G network.

[0080] The vehicle-mounted soil sampling data acquisition and control method provided by this invention automates the sampling, detection, numbering and uploading process through a systematic control process, reduces manual intervention, improves the efficiency of sampling tasks and the consistency of data management, and ensures the traceability of data.

[0087] In one embodiment, when the processor 4001 executes the vehicle-mounted soil sampling data acquisition control program in the memory 4002, the following steps can be implemented: Power on, start the system via the onboard computing unit and load the preset sampling task parameters to complete system preparation; The vehicle's real-time location data is collected by the GPS positioning unit and transmitted to the on-board computing unit; the on-board computing unit calls the preset sampling point grid parameters to determine the target sampling point and generate a sampling path; the vehicle is driven to the target sampling point along the sampling path; The system sends a soil sampling command to the system control box, controlling the multi-stage telescopic lifting rod to extend to a preset depth and the soil sampling drill bit to rotate and sample soil; the soil sampling depth data is collected by a depth sensor and transmitted to the system control box; after soil sampling is completed, the multi-stage telescopic lifting rod is retracted and the drill bit discharges the soil sample into a sample bag; soil parameters are detected by a soil multi-sensor unit and transmitted to the system control box; at the same time, the conical compaction head of the soil compaction detection unit presses down, and the soil resistance value is detected by a resistance sensor and transmitted to the system control box; A unique soil sample number is generated by the sample identification unit and transmitted to the vehicle-mounted computing unit; a label with the unique soil sample number is printed by a thermal printer and affixed to the sample bag; the vehicle-mounted computing unit binds the sampling point coordinates, soil parameters, soil sampling depth, and resistance value with the unique soil sample number to generate and store a structured dataset. The system receives structured datasets via a wireless communication unit and uploads them to the cloud platform at preset time intervals via a WiFi link. When the WiFi signal strength is detected to be lower than a preset threshold, it automatically switches to a 4G / 5G link to continue uploading, thus completing a single sampling.

[0088] It should be understood that when the processor 4001 executes the control program for the vehicle-mounted soil sampling data acquisition device in the memory 4002, in addition to the functions mentioned above, it can also perform other functions, as detailed in the description of the corresponding method embodiments above.
