Description

Technical Field

[0001] This utility model relates to the field of soil testing, specifically a vehicle-mounted soil testing device. Background Technology

[0002] Soil is a vital natural resource and the material foundation for agricultural development. Without soil, there is no agriculture, and therefore no basic raw materials for human survival, such as clothing and food. Currently, common soil testing methods primarily rely on manual sampling and laboratory-based physical or chemical analysis, such as inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectrometry (AAS). These methods are time-consuming, and due to the uncertainty of on-site sampling points, they cannot accurately reflect the actual condition of the entire soil plot. Although CN211826542U discloses a gamma spectrometer with storage and wireless transmission capabilities, effectively solving the problem of untimely data processing, it still only performs gamma spectral analysis and cannot combine GPS data to recommend reasonable sampling points or combine soil data from sampling points with gamma spectral data to create a digital soil map.

[0003] With the development of 3S information technology and sensor technology, spatial limitations can be greatly reduced, the impact of environmental and climatic factors on monitoring can be eliminated, and information collection and analysis of specific areas can be completed quickly to obtain high-resolution digital soil maps. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of long processing time for soil sample analysis in laboratories, uncertainty of manual sampling points, inability to accurately reflect real soil data, and inability to generate soil digital maps. This invention provides a vehicle-mounted soil testing device that can conveniently and quickly acquire soil information and generate soil digital maps.

[0005] The technical solution adopted in this utility model is:

[0006] A vehicle-mounted soil testing device includes a gamma spectrometer, an RTK mobile station, an RTK base station, a data acquisition unit, a vehicle-mounted rugged computer, a barcode scanner, and a label printer. The device is characterized in that: the gamma spectrometer is connected to the data acquisition unit via a data cable; the data acquisition unit is connected to the network port of the vehicle-mounted rugged computer via a network cable; the barcode scanner and label printer are wirelessly connected to the vehicle-mounted rugged computer via USB cable or Bluetooth; the RTK base station is connected to the RTK mobile AK station using the LoRa protocol; and the RTK mobile station is connected to the vehicle-mounted rugged computer via a Bluetooth virtual serial port.

[0007] The vehicle-mounted tri-proof computer is equipped with a data processing system that can record the vehicle's positioning data and the scanning data of the gamma spectrometer in real time. At the same time, it can automatically calculate reasonable soil sampling points based on the real-time dynamic positioning of the RTK mobile station, generate and store soil sample labels, control the label printer to print soil sample labels, and obtain and store the soil sample numbers that have been sampled through a barcode scanner.

[0008] The vehicle-mounted tri-proof computer data processing system of this utility model has the function of real-time acquisition of soil gamma spectrometer data and vehicle positioning data; by analyzing soil gamma ray data and based on the real-time dynamic positioning of the RTK mobile station, it automatically calculates reasonable soil sampling points, generates soil sample labels and stores them; by combining and analyzing the gamma ray data and soil sample data in the later stage, a high-resolution soil digital map is generated. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings. The gamma spectrometer, RTK mobile station, RTK base station, data acquisition device, vehicle-mounted rugged computer, barcode scanner, and label printer of the present invention are all existing structures.

[0011] like Figure 1 As shown, this utility model discloses a vehicle-mounted soil testing device, comprising a gamma spectrometer, an RTK mobile station, an RTK base station, a data acquisition unit, a vehicle-mounted rugged computer, a barcode scanner, and a label printer. The device is characterized in that: the gamma spectrometer is connected to the data acquisition unit via a data cable; the data acquisition unit is connected to the network port of the vehicle-mounted rugged computer via a network cable; the barcode scanner and label printer are connected to the vehicle-mounted rugged computer via USB cables, or alternatively, via Bluetooth wireless connection; the RTK base station is connected to the RTK mobile station using the LoRa protocol; and the RTK mobile station is connected to the vehicle-mounted rugged computer via a Bluetooth virtual serial port.

[0012] The vehicle-mounted tri-proof computer is equipped with a data processing system that can record the vehicle's positioning data and the scanning data of the gamma spectrometer in real time. At the same time, it can automatically calculate reasonable soil sampling points based on the real-time dynamic positioning of the RTK mobile station, generate and store soil sample labels, control the label printer to print soil sample labels, and obtain and store the soil sample numbers that have been sampled through a barcode scanner.

[0013] This utility model's vehicle-mounted tri-proof computer-installed data processing system includes SoilOptix data logger and ArcGIS software. SoilOptix data logger is data acquisition and analysis software for an energy dispersive spectrometer, while ArcGIS is digital soil mapping software; both are existing technologies. The data processing system has the function of real-time acquisition of soil gamma-ray spectrometer data and vehicle positioning data. By analyzing soil gamma-ray data and based on real-time dynamic positioning using an RTK rover, it automatically calculates reasonable soil sampling points, generates soil sample labels, and stores them. Through subsequent combined analysis of gamma-ray data and soil sample data, a high-resolution digital soil map is generated.

[0014] The specific workflow is as follows: First, power on the RTK base station and RTK rover, and connect the vehicle-mounted rugged computer to the RTK rover. After the GPS signal is normal, start the vehicle equipped with the rugged computer and drive it around the field to be tested. Once the data processing system on the rugged computer has acquired the outline of the field, it will automatically plan the vehicle's driving path. Power on the gamma spectrometer and connect it to the vehicle-mounted rugged computer via the data acquisition unit, then drive along the path planned by the data processing system. After completing all paths, pause the gamma spectrometer; the data processing system will automatically mark the coordinates of the points where soil samples need to be taken. After driving the vehicle to the designated coordinates, the label printer will automatically print soil sample labels. After soil sampling, use a barcode scanner to input the soil sample labels into the data processing system. Repeat the above operations to complete sampling at all coordinate points. After completing the gamma spectrometer scan of the entire field and obtaining the soil sample results, the data processing system will process the gamma spectrometer data and soil sample results to generate a high-resolution digital soil map with 56 data points per acre.
