Description

Technical Field

[0001] This invention relates to the field of environmental monitoring and early warning, and specifically to a mobile soil pollution monitoring and early warning device. Background Technology

[0002] With the acceleration of industrialization and the transformation of agricultural production methods, soil pollution has become increasingly serious, posing a severe threat to the ecological environment and human health. In mountainous areas like western Hunan, sloping farmland faces challenges such as complex terrain, concentrated rainfall, and severe soil erosion, making soil pollution particularly prominent. These sloping farmlands are not only a vital source of livelihood for local farmers but also a key area for protecting ecological security and promoting sustainable development. However, traditional soil pollution monitoring methods often rely on manual soil sample collection and chemical analysis in laboratories. This approach is not only time-consuming and labor-intensive but also has a limited monitoring scope, making it difficult to detect and address soil pollution problems in a timely manner.

[0003] The remediation of soil pollution on sloping farmland in western Hunan faces numerous challenges. On the one hand, due to terrain limitations, comprehensive monitoring coverage is difficult, resulting in incomplete data collection and an inability to accurately reflect the soil pollution status. On the other hand, most existing monitoring equipment is fixed in a single location, lacking flexibility and failing to adapt to varying slopes and soil conditions. Furthermore, the real-time nature and accuracy of data during monitoring are also pressing issues that need to be addressed.

[0004] While some soil pollution monitoring devices exist on the market, most suffer from limitations such as limited monitoring range, incomplete data due to fixed-location monitoring, complex operation, and low levels of intelligence. These shortcomings make it difficult for existing equipment to meet the actual needs of soil pollution remediation on sloping farmland in western Hunan. Therefore, a new type of mobile soil pollution monitoring and early warning device is needed, capable of real-time monitoring of soil pollution, automatic lifting and lowering adjustment, stable fixation, and intelligent early warning functions. This would meet current needs for soil pollution monitoring and early warning, providing strong technical support for soil pollution remediation on sloping farmland in western Hunan. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a mobile soil pollution monitoring and early warning device, which aims to achieve functions such as real-time monitoring, automatic lifting and adjustment, stable fixation, and intelligent early warning, providing strong technical support for the remediation of soil pollution on sloping farmland in western Hunan.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A mobile soil pollution monitoring and early warning device includes a mobile module, on which a fixed component, a monitoring component, and an early warning component are installed. The mobile module includes a vehicle body, a driving component is fixedly connected to the top wall of the vehicle body, a power component is coaxially fixedly connected to the output shaft of the driving component, a lead screw is coaxially fixedly connected to the output shaft of the power component, a nut seat is sleeved on the lead screw, the nut seat and the lead screw form a ball screw structure, a moving ring is vertically slidably fitted on the outer wall of the nut seat, limit components are installed on both sides of the top of the moving ring, and the fixed component is installed on the moving ring, with the fixed component evenly distributed along the circumference of the moving ring.

[0007] The fixing component includes a connecting rod, one end of which is hinged to a movable ring, and the other end of which is hinged to a mounting plate. The mounting plate is fixedly connected to the inner side wall of the vehicle body. A through groove is provided on the connecting rod, and a driven rod is hinged in the through groove. Auxiliary rod assemblies are installed on both sides of the driven rod. A fixing plate is hinged to the end of the driven rod away from the connecting rod, and an insert rod is fixedly connected to the side of the fixing plate away from the driven rod.

[0008] The end of the lead screw away from the power component has a mounting groove. The monitoring component is installed in the mounting groove, and the warning component is installed on the outer side wall of the vehicle body. The monitoring component is connected to a controller. The controller is connected to the drive component, the power component, and the warning component. The controller controls the opening and closing of the drive component and the power component. The warning component is used to warn the operator based on the real-time monitoring data of the monitoring component.

[0009] The technical principle of the above solution is as follows: The mobile module is mainly composed of a vehicle body. A drive component is fixedly connected to the top wall inside the vehicle body. A power component is coaxially fixedly connected to the output shaft of the drive component. A lead screw is then coaxially fixedly connected to the output shaft of the power component. This design allows the motor to drive the lead screw to rotate through a reducer. A nut seat is fitted on the lead screw, forming a ball screw structure with the lead screw. This structure can convert the rotational motion of the lead screw into the linear motion of the nut seat. A moving ring is vertically slidably fitted on the outer wall of the nut seat. The moving ring moves up and down along the direction of the lead screw under the drive of the nut seat.

[0010] The fixed assembly is hinged to the moving ring via a connecting rod, with a mounting plate hinged to the other end of the connecting rod. The mounting plate is fixedly connected to the inner side wall of the vehicle body. This hinged design allows the fixed assembly to swing within a certain range. A through slot is formed on the connecting rod, within which a driven rod is hinged. Auxiliary rod assemblies are mounted on both sides of the driven rod. These assemblies together form a linkage mechanism, enabling the driven rod to drive the fixed plate to swing horizontally. An insertion rod is fixedly connected to the fixed plate, used for insertion into the soil for fixation, ensuring the stability of the device during monitoring.

[0011] The monitoring component is installed in a mounting slot at the end of the lead screw furthest from the power component, for real-time monitoring of soil pollution. The early warning component is installed on the outer wall of the vehicle body and connected to the controller. The controller receives real-time monitoring data from the monitoring component and determines whether to issue an early warning signal based on preset thresholds. The controller is also connected to the drive and power components, enabling control of their operation and thereby adjusting the monitoring position and depth of the monitoring component.

[0012] The above approach has the following beneficial effects:

[0013] 1. This solution, through the cooperation of drive and power components, achieves the rotation of the lead screw, which in turn drives the nut seat to move along the lead screw axis. Compared with existing monitoring methods that require manual adjustment or fixed positions, this design allows the monitoring components to be automatically raised and lowered within the vehicle body, improving the flexibility and accuracy of monitoring and enabling more comprehensive coverage of soil pollution at different depths.

[0014] 2. In this design, the fixing assembly utilizes a hinged structure consisting of a connecting rod, a driven rod, and an auxiliary rod assembly to achieve flexible swinging and positioning of the fixing plate and the insertion rod. This design not only enhances the stability and reliability of the device but also allows the insertion rod to be easily inserted into the soil to fix the monitoring point, avoiding displacement or shaking during the monitoring process and improving the accuracy of the monitoring data.

[0015] 3. In this solution, the monitoring components are connected to the controller via signal transmission, enabling real-time monitoring of soil pollution data and feeding the data back to the controller. Compared to existing technologies that require manual data collection and analysis, this design achieves automated data collection and processing, significantly improving monitoring efficiency and accuracy. Simultaneously, the controller can intelligently control the drive and power components based on the monitoring data, achieving automatic adjustment of the monitoring components and further enhancing the device's intelligence level.

[0016] 4. In this solution, the early warning component can issue warnings to operators based on real-time monitoring data from the monitoring components. When soil pollution data exceeds a preset threshold, the early warning component will promptly issue an alarm, reminding operators to take appropriate measures. Compared with existing technologies that lack real-time early warning functionality, this design can promptly detect and address soil pollution problems, effectively reducing environmental pollution risks and protecting the ecological environment and public health.

[0017] In summary, the device of the present invention has significant advantages such as flexible lifting and adjustment, stable and reliable fixing, high monitoring efficiency, high level of intelligence, and strong real-time early warning function, providing strong technical support for soil pollution monitoring and early warning.

[0018] Furthermore, the monitoring component includes a housing, which is detachably connected to the mounting slot. A pressure sensor, a pH sensor, an organic matter content sensor, and a heavy metal content sensor are embedded in the side wall of the housing. All of these sensors are connected to the controller. The pressure sensor measures the pressure exerted by the soil on the device probe; the pH sensor monitors the soil's acidity and alkalinity in real time; the organic matter content sensor measures the content of organic matter in the soil; and the heavy metal content sensor detects the content of heavy metal elements in the soil.

[0019] Beneficial Effects: The pressure sensor measures the pressure exerted by the soil on the device probe. This data is crucial for understanding soil compaction, moisture, and potential compaction problems. The pH sensor monitors soil acidity and alkalinity in real time. Continuous pH monitoring allows for the timely detection of soil acid-base imbalances, providing a basis for adjusting soil pH and optimizing the crop growth environment. The organic matter content sensor measures the content of organic matter in the soil. Monitoring organic matter content allows for the assessment of soil fertility, guiding the application of organic fertilizers and improving soil productivity. The heavy metal content sensor detects the content of heavy metal elements in the soil. The heavy metal content sensor in this solution can monitor the content of heavy metals in the soil in real time, promptly identifying pollution problems and providing data support for taking appropriate remediation measures.

[0020] Furthermore, the early warning component includes indicator lights and a buzzer. The indicator lights are used to flash and emit different colors of light to indicate different early warning reminders, and the buzzer is used to emit different alarm sounds. Both the indicator lights and the buzzer are connected to the controller signal. When the controller determines that the real-time monitoring data of the monitoring component exceeds the preset threshold, the early warning module issues an audible and visual alarm signal.

[0021] Beneficial Effects: The early warning component can issue an alarm signal the instant that monitored data exceeds the threshold, ensuring that operators can quickly obtain pollution warning information and take timely countermeasures to prevent the pollution from spreading or worsening. Through the flashing colors of indicator lights and the different alarm sounds of the buzzer, the early warning component provides intuitive and easily identifiable warning signals. This allows operators to quickly understand the pollution situation and urgency level even without detailed data reports. The design of the early warning component allows for adjustment of the warning threshold and alarm signal according to actual needs. This means that the device can adapt to different monitoring requirements and pollution standards, improving its applicability and flexibility.

[0022] Furthermore, the auxiliary rod assembly includes a first auxiliary rod and a second auxiliary rod. One end of the first auxiliary rod is hinged to the mounting plate, the other end of the first auxiliary rod is hinged to the second auxiliary rod, and the end of the second auxiliary rod away from the first auxiliary rod is hinged to the fixing plate.

[0023] Beneficial Effects: The auxiliary rod assembly, through its quadrilateral linkage structure, effectively enhances the stability of the fixing component in the soil. When the insertion rod is inserted into the soil, the auxiliary rod assembly can disperse and resist the reaction force from the soil, preventing the fixing component from tilting or loosening due to uneven stress. Due to its hinged design, the auxiliary rod assembly can adapt to different soil hardness and terrain conditions to a certain extent. When the soil is hard, the auxiliary rod assembly maintains minimal deformation, ensuring smooth insertion of the insertion rod; while when the soil is soft, the auxiliary rod assembly can undergo a certain degree of elastic deformation to better conform to the soil surface and improve the fixing effect.

[0024] Furthermore, the vehicle body includes a cargo box, and the bottom of the cargo box is equipped with rollers with braking function. The rollers are omnidirectional wheels.

[0025] Beneficial Effects: The rollers and casters with braking function allow the device to move easily across various terrains, including flat ground, rugged mountain paths, or muddy fields. Operators can easily push or pull the device to designated monitoring points, greatly improving work efficiency. The casters allow the device to turn and adjust omnidirectionally during movement, ensuring its stability and flexibility in complex terrain conditions. This enables the device to more accurately locate monitoring points, avoiding monitoring errors caused by terrain limitations. The braking function allows the device to stop quickly when needed, preventing damage or personal injury caused by accidental slippage or rolling.

[0026] Furthermore, an interactive module is embedded in the side wall of the vehicle body. The interactive module includes a display screen and an operating unit. Both the display screen and the operating unit are connected to the controller signal. The display screen is used to display the soil data collected by the monitoring components in real time. The soil data includes information on pressure, pH value, organic matter content, and heavy metal content. The operating unit includes several function buttons and adjustment knobs, which allow operators to manually control and set the device.

[0027] Beneficial Effects: Real-time display of monitoring data allows operators to quickly obtain soil pollution information without waiting for data processing or report generation. Simultaneously, the user-friendly design of the control unit enables operators to quickly control and configure the device, improving the efficiency of monitoring tasks. The interactive module design allows operators to complete complex monitoring and control tasks using simple buttons and knobs. This intuitive and easy-to-use interface reduces operational difficulty, making it easy for non-professionals to learn. The display screen presents monitoring data graphically and intuitively, enabling operators to clearly understand the soil pollution status and trends, helping them make more accurate judgments and decisions.

[0028] Furthermore, a power module is also installed inside the vehicle body. The power module is connected to the controller via signal. The power module includes a battery and a charging port. The charging port is electrically connected to the battery and is used by the user to connect an external power source to charge the battery. The charging port is embedded in the side wall of the vehicle body.

[0029] Solar panels are installed on the top wall of the vehicle body. The solar panels are used to capture sunlight and convert it into electrical energy. Several solar inverters are installed below the solar panels. The solar inverters are fixedly connected to the top wall inside the outer casing. The solar panels are electrically connected to the solar inverters, and the solar inverters are electrically connected to the power module.

[0030] Beneficial effects: The power module includes a battery and charging port, allowing users to charge the battery by connecting to an external power source, ensuring the device has sufficient power when needed. The installation of solar panels further enhances the device's energy self-sufficiency. By capturing sunlight and converting it into electricity, solar panels provide a continuous power supply to the power module, reducing dependence on external power sources. The use of solar panels is a green and environmentally friendly way to obtain energy, reducing the device's reliance on fossil fuels and helping to reduce carbon emissions and environmental pollution.

[0031] With ample power reserves, the device can continuously monitor soil pollution, extending the working time of each deployment and reducing the need for frequent charging or battery replacements. The presence of solar panels is particularly important at monitoring sites that are remote or difficult to access power, ensuring the device can operate continuously and stably.

[0032] Furthermore, it also includes a positioning module, which is installed on the vehicle body and is connected to the controller signal. The positioning module is used to obtain the current location information of the device in real time and display it on the display screen of the interaction module.

[0033] Beneficial Effects: The positioning module can acquire the device's current location information in real time, including longitude, latitude, and altitude. This information is transmitted to the interactive module's display screen via the controller. When the device is started and begins soil pollution monitoring, the positioning module starts simultaneously, ensuring the synchronization and accuracy of monitoring data and location information. Combining the location information provided by the positioning module with soil data collected by the monitoring components (such as pressure, pH value, organic matter content, heavy metal content, etc.), operators can gain a comprehensive understanding of the soil pollution status at the monitoring site. This combination not only improves the accuracy of monitoring but also enhances the reliability and credibility of the data.

[0034] Furthermore, a circular hole is provided on the bottom wall of the vehicle body, and a cleaning component is installed at the circular hole. The cleaning component includes a cleaning brush, which is distributed along the circumference of the circular hole.

[0035] Beneficial Effects: During long-term use, soil impurities and residues easily accumulate on the surface of monitoring components, which may affect the accuracy and reliability of monitoring data. The cleaning component effectively removes soil impurities and residues from the surface of the monitoring component's housing, keeping it clean and thus ensuring the accuracy and reliability of the monitoring data. The cleaning component includes cleaning brushes distributed circumferentially along the circular holes, which automatically clean the monitoring component when it is retracted. This design avoids the tedious and time-consuming manual cleaning, improving work efficiency.

[0036] Furthermore, it also includes a wireless communication module, which is installed on the vehicle body and is connected to the controller. The wireless communication module is used to transmit real-time data from the monitoring components, location information from the positioning module, and alarm signals from the early warning components to the remote monitoring center in real time.

[0037] It also includes a data storage module, which is connected to the controller signal. The data storage module is used to store soil data collected by the monitoring components, location information obtained by the positioning module, and the device's operation log information.

[0038] Beneficial effects: The wireless communication module can transmit real-time data from monitoring components, location information from the positioning module, and alarm signals from the early warning component to the remote monitoring center in real time. This allows monitoring personnel to obtain monitoring data and status information from the device anytime, anywhere, enabling remote real-time monitoring of the monitoring points. Remote monitoring via the wireless communication module reduces the need for on-site monitoring personnel, lowering labor costs. Simultaneously, the remote monitoring center can centrally process and analyze data from multiple monitoring points, improving work efficiency.

[0039] The data storage module can store soil data collected by the monitoring components, location information acquired by the positioning module, and operational logs of the device. This allows for persistent data storage, facilitating subsequent data analysis and traceability. By storing historical data, long-term soil pollution monitoring and analysis can be supported. This helps to discover trends and patterns in soil pollution, providing a scientific basis for environmental protection and remediation. The data storage module also has data backup and recovery functions to prevent data loss or damage. This enhances data reliability and availability, ensuring the continuity and stability of monitoring work.

[0050] The following detailed description illustrates the specific implementation method:

[0051] Example 1:

[0052] As attached Figures 1 to 5 The image shows a mobile soil pollution monitoring and early warning device, comprising a mobile module, a fixed component, a monitoring component, and an early warning component mounted on the mobile module. The monitoring component includes a housing. A pressure sensor, a pH sensor, an organic matter content sensor, and a heavy metal content sensor are embedded in the side wall of the housing. All three sensors are connected to a controller. The pressure sensor measures the pressure exerted by the soil on the device probe, thereby assessing soil compaction and permeability and monitoring soil physical properties. The pH sensor monitors soil acidity and alkalinity in real time. Soil pH is a key factor affecting plant growth and nutrient availability; monitoring it allows for timely detection of soil acid-base imbalances. The organic matter content sensor measures the content of organic matter in the soil. Organic matter is an important component of soil fertility and has a significant impact on soil structure, water retention capacity, and nutrient cycling. The heavy metal content sensor detects the content of heavy metal elements in the soil. Heavy metal pollution is a significant problem in soil pollution, posing a potential threat to the environment and human health.

[0053] The early warning component includes indicator lights and a buzzer (neither shown in the diagram). The indicator lights flash and emit different colors to indicate different warning alerts, while the buzzer emits different alarm sounds. Both the indicator lights and the buzzer are connected to the controller. When the controller determines that the real-time monitoring data of the monitoring component exceeds a preset threshold, the early warning module issues an audible and visual alarm signal. For example, red in the indicator light indicates severe pollution, yellow indicates mild pollution, and green indicates no pollution. A long beep from the buzzer indicates severe pollution, and a short beep indicates mild pollution.

[0054] The mobile module includes a vehicle body, which includes a cargo box 1. The cargo box 1 has an opening at its bottom and is equipped with braked casters 2. These casters are omnidirectional, facilitating movement and positioning of the device during monitoring. Handles are bolted to the side walls of the cargo box 1. A circular hole 18 is formed in the bottom wall of the cargo box 1, and a cleaning component is installed at this hole. The cleaning component includes cleaning brushes distributed around the circumference of the circular hole 18 to remove soil impurities and residues from the surface of the monitoring component's outer casing, maintaining the cleanliness and accuracy of the monitoring component.

[0055] A drive component is fixedly connected to the top wall of the vehicle body. In this embodiment, the drive component is a cylinder 3. A power component is fixedly connected to the output shaft of the drive component. In this embodiment, the power component is a motor 4. A lead screw 5 is fixedly connected to the output shaft of the power motor. A nut seat 6 is sleeved on the lead screw 5. The nut seat 6 and the lead screw 5 form a ball screw structure. A moving ring 7 is vertically slidably fitted on the outer wall of the nut seat 6. Limiting components 8 are installed on both sides of the top of the moving ring 7. In this embodiment, the limiting components 8 are elastic connecting ropes. Fixing components are installed on the moving ring 7 and are evenly distributed along the circumference of the moving ring 7.

[0056] The fixing assembly includes a connecting rod 9, one end of which is hinged to a movable ring 7, and the other end of which is hinged to a mounting plate 10. The mounting plate 10 is fixedly connected to the inner side wall of the vehicle body. A through groove 901 is provided on the connecting rod 9, and a driven rod 11 is hinged in the through groove 901. Auxiliary rod assemblies are installed on both sides of the driven rod 11. A fixing plate 12 is hinged to the end of the driven rod 11 away from the connecting rod 9, and an insert rod 13 is fixedly connected to the side of the fixing plate 12 away from the driven rod 11. The auxiliary rod assembly is located between the mounting plate 10 and the fixing plate 12. The auxiliary rod assembly includes a first auxiliary rod 15 and a second auxiliary rod 16. One end of the first auxiliary rod 15 is hinged to the mounting plate 10, and the other end of the first auxiliary rod 15 is hinged to the second auxiliary rod 16. The end of the second auxiliary rod 16 away from the first auxiliary rod 15 is hinged to the fixing plate 12.

[0057] The lead screw 5 has a mounting groove 14 at the end furthest from the power component. The housing is detachably connected to the mounting groove 14 by bolts, facilitating maintenance and replacement of the monitoring component. The monitoring component is installed in the mounting groove 14, and the warning component is installed on the outer wall of the vehicle body. The monitoring component is signal-connected to a controller, which is signal-connected to the drive component, power component, and warning component. The controller controls the opening and closing of the drive component and power component. The warning component is used to provide warnings to the operator based on the real-time monitoring data of the monitoring component. A power module is also provided inside the vehicle body 1. The power module is signal-connected to the controller and includes a battery and a charging port. The charging port is electrically connected to the battery and is used by the user to connect an external power source to charge the battery. The charging port is embedded in the side wall of the vehicle body 1.

[0058] The specific implementation process is as follows: First, the outer shell of the monitoring component is detachably connected to the mounting slot 14 using bolts, ensuring that core components such as the pressure sensor, pH sensor, organic matter content sensor, and heavy metal content sensor are correctly installed and in working condition. These sensors are crucial for monitoring soil pollution, as they can collect various soil data in real time. Simultaneously, the controller sets the warning thresholds and corresponding audible and visual signals for the warning components (including indicator lights and buzzers) to promptly issue alarms when soil pollution exceeds standards. The power module installed inside the vehicle compartment 1 provides stable power support for the entire device, ensuring continuous monitoring. When the battery is low, the operator can connect to an external power source through the charging port embedded in the side wall of the vehicle compartment 1 for charging, ready for the next use.

[0059] Next, the operator pushes the vehicle with a handle, utilizing the omnidirectional wheels with brakes to easily move the device to the soil area to be monitored. During the movement, the operator can flexibly adjust the position of the vehicle to ensure that the monitoring components accurately contact the soil, while preventing the device from tilting or becoming unstable, thus guaranteeing the accuracy of the monitoring data.

[0060] Upon reaching the monitoring point, the operator starts motor 4 via the controller. As motor 4 rotates, it drives the lead screw 5 to rotate. Because a ball screw structure is formed between the lead screw 5 and the nut seat 6, the nut seat 6 moves downwards along the lead screw 5 as it rotates. This movement of the nut seat 6 causes the sliding ring 7, which is vertically slidably engaged with it, to move downwards as well.

[0061] As the moving ring 7 moves downward, the limiting components 8 installed on both sides of its top provide stability and guidance, ensuring that the moving ring 7 does not deviate from the track during its descent. Simultaneously, the downward movement of the moving ring 7 also drives the connecting rod 9 downward. During its movement, the connecting rod 9 forms a linkage mechanism. This linkage mechanism, through the hinge relationship between the connecting rod 9 and the driven rod 11, and the transmission and conversion effects of the auxiliary rod assemblies (including the first auxiliary rod 15 and the second auxiliary rod 16) installed on both sides of the driven rod 11, achieves the downward pressing action of the fixed plate 12. During the downward movement of the fixed plate 12, the insertion rod 13, fixedly connected to the side away from the driven rod 11, passes through the opening at the bottom of the carriage 1 and is also inserted into the soil. The design of the insertion rod 13 ensures that the device is firmly fixed in the soil, avoiding inaccurate monitoring data caused by device shaking or movement during monitoring.

[0062] At this point, the operator activates cylinder 3 via the controller. The output end of cylinder 3 extends, pushing the monitoring component at the bottom of the lead screw 5 downwards, thus inserting the outer casing of the monitoring component into the soil for monitoring. The operator controls the extension length of the cylinder 3 output end via the controller, allowing the monitoring component to be inserted into the soil at different depths. The sensors within the monitoring component begin operating, collecting real-time data on soil pressure, pH value, organic matter content, and heavy metal content, transmitting this data to the controller via signal lines. The controller analyzes and processes this data; if any data exceeds a preset threshold, it immediately triggers an audible and visual alarm. Based on the flashing colors of the indicator lights and the alarm sound of the buzzer, the operator can quickly determine the degree of soil contamination and take appropriate measures. After monitoring is complete, the monitoring component is retracted via cylinder 3, and simultaneously, the reverse action of motor 4 and cylinder 3 is activated, restoring the device to its initial state. The cleaning component removes soil impurities and residues from the surface of the monitoring component's casing. Specifically, when the monitoring component is retrieved, it passes through the circular hole 18, where a cleaning brush removes these impurities and residues, thus avoiding the tedious and time-consuming manual cleaning and improving work efficiency. Finally, the operator moves the vehicle to the next monitoring point or returns by pushing it with a handle.

[0063] Example 2:

[0064] The difference from Embodiment 1 is that an interactive module is embedded in the side wall of the vehicle body 1. This module includes a display screen 17 and an operating unit, both of which are connected to the controller. The display screen 17 displays real-time soil data collected by the monitoring components, including pressure, pH value, organic matter content, and heavy metal content. The display screen 17 provides a clear visual representation of soil pollution, allowing operators to quickly understand the monitoring results. The operating unit includes various function buttons and adjustment knobs, allowing operators to manually control and set the device. The function buttons are used to start and stop monitoring tasks, switch display modes, etc.; the adjustment knobs are used to adjust warning thresholds, set monitoring depth, and other parameters, improving the device's flexibility and operability.

[0065] The specific implementation process is as follows: During use, operators can further set and calibrate the device through the display screen 17 of the interactive module and the operating unit. During monitoring, operators can view the changes in monitoring data in real time through the display screen 17, including dynamic updates of information such as pressure, pH value, organic matter content, and heavy metal content. If abnormal data is detected or the warning threshold is exceeded, the warning component will issue an audible and visual alarm signal, and the corresponding alarm information will also be displayed on the display screen 17 to remind operators to take timely measures.

[0066] Operators can manually control the device via the control panel, such as pausing monitoring or adjusting the monitoring depth, to obtain more accurate soil pollution information. After monitoring is completed, operators can view historical monitoring data on display screen 17 and perform data analysis and recording. Display screen 17 can display trend graphs, bar charts, and other chart formats to help operators understand the changes and trends in soil pollution more intuitively.

[0067] Example 3:

[0068] The difference from Embodiment 2 is that a solar panel is installed on the top wall of the vehicle body 1. The solar panel is used to capture sunlight and convert it into electrical energy. Several solar inverters are installed below the solar panel. The solar inverters are fixedly connected to the top wall inside the outer casing. The solar panel is electrically connected to the solar inverter and the solar inverter is electrically connected to the power module.

[0069] The specific implementation process is as follows: When there is sunshine outdoors, the solar panels begin to capture sunlight and convert it into electrical energy. The generated direct current (DC) is automatically transmitted to the solar inverter, which converts the DC to alternating current (AC). The AC can be directly used by this device, such as driving the display screen 17, the operating unit, and monitoring components. If the device does not currently require electrical energy, the energy is stored in the power module, such as a battery or supercapacitor, for later use. The operating status of the solar panels, solar inverter, and power module can be monitored through the controller. Based on the device's power demand and solar power generation, the energy usage and storage strategies are intelligently adjusted.

[0070] Regularly check the operating status of solar panels and solar inverters to ensure they are functioning properly. Clean dust and dirt from the surface of solar panels to improve their photoelectric conversion efficiency. Utilizing solar energy as a clean energy source reduces dependence on traditional energy sources. Solar inverters convert generated electricity into the alternating current required by the device, improving energy utilization.

[0071] Example 4:

[0072] As attached Figure 5 As shown, the difference from Embodiment 3 is that it also includes a positioning module. In this embodiment, the positioning module is a Beidou positioning module. The positioning module is installed on the vehicle body and is connected to the controller signal. The positioning module is used to obtain the current location information of the device in real time and display it on the display screen 17 of the interactive module.

[0073] The specific implementation process is as follows: When the device is started and begins soil pollution monitoring, the Beidou positioning module is simultaneously activated to acquire the device's current location information in real time. The location information acquired by the Beidou positioning module (including longitude, latitude, altitude, etc.) is transmitted to the display screen 17 of the interactive module via the controller. The display screen 17 updates and displays the location information of the current monitoring location in real time, allowing operators to intuitively see the specific location of the monitoring site.

[0074] By combining soil data collected by the monitoring components (such as pressure, pH value, organic matter content, heavy metal content, etc.) with location information from the BeiDou positioning module, operators can gain a comprehensive understanding of the soil pollution status at the monitoring site. Display screen 17 can show the location of the monitoring site in map form, and simultaneously mark the data for each monitoring point on the map, using different colors or icons to represent different levels of pollution. Combined with location information, soil pollution distribution maps, trend charts, and other graphs can be generated, providing a scientific basis for environmental protection and remediation.

[0075] Example 5:

[0076] As attached Figure 5 As shown, the difference from Embodiment 4 is that it also includes a wireless communication module (a suitable wireless communication module is selected according to data transmission requirements (such as data volume, transmission speed, coverage, etc., such as 4G / 5G module, LoRa module, NB-IoT module, etc.). The wireless communication module is installed on the vehicle body and is connected to the controller signal. The wireless communication module is used to transmit the real-time data of the monitoring component, the location information of the positioning module, and the alarm signal of the early warning component to the remote monitoring center in real time.

[0077] It also includes a data storage module (selecting a suitable data storage module based on data storage requirements (such as storage capacity, read / write speed, data security, etc.), such as solid-state drives (SSDs), hard disk drives (HDDs), flash memory cards, etc.). The data storage module is connected to the controller signal and is used to store soil data collected by the monitoring components, location information obtained by the positioning module, and the device's operation log information.

[0078] The specific implementation process is as follows: Configure the network parameters of the wireless communication module, such as APN, username, and password, to ensure that the module can successfully connect to the specified mobile communication network or IoT platform. Test the communication performance of the wireless communication module to ensure the stability and reliability of data transmission.

[0079] The wireless communication module receives real-time data from the monitoring components, location information from the positioning module, and alarm signals from the early warning components transmitted from the controller. The wireless communication module packages the received data and information and transmits it to the remote monitoring center in real-time via a mobile network or IoT platform. The remote monitoring center is configured with a corresponding receiving system or platform to receive and analyze the data and information from the wireless communication module in real time. The data and information are displayed on the interface of the remote monitoring center, facilitating real-time monitoring and analysis by management personnel.

[0080] Configure the storage parameters of the data storage module, such as partitions and file system type, to ensure the module can store data correctly. Initialize the data storage module to ensure optimal data storage and retrieval performance. The data storage module receives soil data collected by monitoring components from the controller, location information obtained by the positioning module, and operational log information from the device in real time. The data storage module stores the received data and periodically exports or backs up the stored data according to the set backup strategy to prevent data loss or corruption. Managers can access the data in the data storage module through a remote monitoring center or local devices to perform data analysis, report generation, and other operations. Based on the data analysis results, managers can formulate corresponding environmental protection measures or early warning strategies to address potential soil pollution problems.

[0081] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
