[0022] Wetland ecosystems have important ecological functions globally, including regulating climate, purifying water quality, maintaining biodiversity, and flood control and disaster reduction. To better manage and protect wetland resources, it is necessary to regularly monitor and sample the water quality and soil of wetlands. These monitoring data are of great significance for evaluating the health status of wetlands, formulating management strategies, and scientific research. However, existing wetland water quality and soil monitoring and sampling devices have many deficiencies in technology, which limit the efficiency and accuracy of monitoring work.

[0023] Manual samplers are one of the most traditional and commonly used devices for wetland water quality and soil monitoring. Common manual samplers include sampling bottles, sampling tubes, sampling shovels, etc. These devices are easy to operate and low in cost, and are widely used in wetland monitoring projects of various scales. Sampling bottle: Used to collect water samples, usually made of plastic or glass, with capacities ranging from dozens of milliliters to several liters. When in use, the sampling bottle is directly placed into the water, taken out after it is filled with water, and sealed for storage. For example, US Patent US6098485A introduces a portable water sample collection bottle with a telescopic bottle body and a sealing cap, which is convenient for carrying and use. Sampling tube: Used to collect water samples and sediment samples, usually made of transparent plastic or metal, with scales and a sealing cap. When in use, the sampling tube is vertically inserted into the water or sediment, taken out after the sample is filled, and sealed for storage. Chinese Patent CN203721545U introduces a multi-layer sediment sampling tube that can collect sediment samples at different depths simultaneously, improving the sampling efficiency and accuracy. Sampling shovel: Used to collect soil samples, usually made of metal, with various shapes, including long-handled and short-handled ones. When in use, the sampling shovel is inserted into the soil, a certain amount of soil sample is taken out, and put into a sampling bag or container. US Patent US5673594A introduces a multi-functional soil sampling shovel with various attachments that can be replaced according to different sampling requirements. The advantages of manual samplers are easy operation and low cost, making them suitable for small-scale or temporary monitoring projects. However, their disadvantages are also very obvious, mainly including: Low sampling efficiency: Manual samplers require manual operation, and each sampling takes a certain amount of time and manpower. Especially in the case of large-area wetlands or multiple sampling points, the sampling efficiency is very low. Poor sampling accuracy: Manual operation is prone to introducing errors, resulting in inaccurate sampling results. In addition, it is difficult to standardize the selection of sampling points and the control of sampling time, which are easily affected by human factors. Complicated data processing: Manual samplers usually do not have on-site data processing and transmission functions, and the samples need to be taken back to the laboratory for analysis, increasing the complexity and time cost of data processing. Large ecological disturbance: Traditional manual sampling methods often cause certain disturbances to the wetland ecosystem, affecting the ecological balance.

[0024] With the development of technology, some semi-automatic samplers have begun to be applied in wetland water quality and soil monitoring projects. Semi-automatic samplers are usually equipped with some basic automation functions, such as timed sampling, fixed-point sampling, etc., which improve the efficiency and accuracy of sampling. Timed sampler: Used to automatically collect water samples at specific time intervals, usually consisting of a sampling bottle, a timed controller, and an electric pump. When in use, install the timed sampler in the water body, set the sampling time and frequency, and the device will automatically collect and save the water samples. US Patent US5557007A introduces a timed water sample collector that has multiple sampling bottles and can automatically collect multiple water samples at set time intervals. Fixed-point sampler: Used to automatically collect water samples or soil samples at specific locations, usually consisting of a sampling tube, a positioning device, and an electric drive device. When in use, install the fixed-point sampler at the designated location, and the device will automatically collect and save the samples. Chinese Patent CN105507885A introduces a fixed-point sediment sampler that has a positioning device and can accurately collect sediment samples at the designated location. Multi-point sampler: Used to collect water samples or soil samples from multiple different locations simultaneously, usually consisting of multiple sampling tubes, an electric drive device, and a control system. When in use, install the multi-point sampler in the water body or soil, and the device will automatically collect multiple samples and save them according to the preset program. US Patent US6189397B1 introduces a multi-point water sample collector that has multiple sampling tubes and can collect water samples from multiple locations simultaneously, improving the efficiency and accuracy of sampling. The advantages of semi-automatic samplers are that they improve the efficiency and accuracy of sampling and reduce the time and labor intensity of manual operation. However, their disadvantages still exist, mainly including: Single function: Semi-automatic samplers usually only have simple timed or fixed-point sampling functions and cannot meet the needs of multi-parameter monitoring. High maintenance cost: The structure of semi-automatic samplers is relatively complex, and the maintenance and repair costs are relatively high, especially in remote areas. Relatively large ecological interference: Although semi-automatic samplers reduce human interference compared to manual samplers, they still have a certain impact on the wetland ecosystem.

[0025] In recent years, some simple automated devices have begun to be applied in wetland water quality and soil monitoring projects. These devices usually have certain intelligent functions, such as automatic sampling, data recording and transmission, etc., which further improve the efficiency and accuracy of sampling. Automatic sampler: It is used to automatically collect water samples or soil samples, and is usually composed of a sampling bottle, an electric pump, sensors and a control system. When in use, the automatic sampler is installed in the water body or soil, and the device will automatically collect samples and save them according to the preset program. US Patent US6276224B1 introduces an automatic water sample collector, which has multiple sampling bottles and electric pumps and can automatically collect multiple water samples according to the set program. Data recorder: It is used to record sampling data, and is usually composed of sensors, a memory and a communication module. When in use, the data recorder is installed near the sampling point, and the device will automatically record sampling data and store it. Chinese Patent CN204007515U introduces a data recorder, which has multiple sensors and a memory and can record multiple environmental parameters, such as temperature, humidity, pH value, etc. Remote monitoring system: It is used to remotely monitor water quality and soil parameters, and is usually composed of sensors, a data recorder, a communication module and a cloud platform. When in use, the remote monitoring system is installed near the sampling point, and the device will automatically collect data and transmit it to the cloud platform through a wireless communication module. Users can access the monitoring data through the Internet. US Patent US8688318B2 introduces a remote water quality monitoring system, which has multiple sensors and a wireless communication module and can monitor water quality parameters in real time and transmit data. The advantages of simple automated devices are that they improve the efficiency and accuracy of sampling, realize real-time recording and remote transmission of data, and reduce the time and cost of laboratory analysis. However, their disadvantages still exist, mainly including: High cost: Simple automated devices usually have a high cost and are not suitable for large-scale or long-term monitoring projects. Limited functions: Simple automated devices usually only have basic sampling and data recording functions and cannot meet complex monitoring needs. Difficult maintenance: Simple automated devices have a complex structure and are difficult to maintain and service, especially in remote areas.

[0026] For existing wetland water quality and soil monitoring sampling devices, whether they are manual samplers, semi-automatic samplers or simple automated devices, the sampling efficiency is generally low. Manual samplers require manual operation, and each sampling takes a certain amount of time and labor. Especially in the case of large-area wetlands or multiple sampling points, the sampling efficiency is very low. Although semi-automatic samplers have certain automated functions, they still require manual installation and maintenance, and the sampling efficiency is limited. Although simple automated devices have improved the sampling efficiency, they have a high cost and are not suitable for large-scale or long-term monitoring projects.

[0027] Existing wetland water quality and soil monitoring sampling devices generally have poor sampling accuracy. Manual samplers rely on manual operation, which is prone to introducing errors and resulting in inaccurate sampling results. Although semi-automatic samplers have certain automation functions, they are still affected by human factors, and it is difficult to standardize the selection of sampling points and the control of sampling time. Simple automated devices have improved sampling accuracy, but the accuracy and stability of sensors still need to be improved, and they are easily affected by environmental factors.

[0028] In existing wetland water quality and soil monitoring sampling devices, the data processing process is generally cumbersome. Manual samplers and semi-automatic samplers usually do not have the functions of on-site data processing and transmission, and the samples need to be taken back to the laboratory for analysis, which increases the complexity and time cost of data processing. Although simple automated devices have the functions of data recording and transmission, data processing and analysis still require professional software and personnel, which increases the cost and difficulty of data processing.

[0029] Existing wetland water quality and soil monitoring sampling devices often cause greater interference to the wetland ecosystem during the sampling process. Manual samplers and semi-automatic samplers require frequent manual intervention, which may not only damage the natural state of the wetland, but also have a negative impact on animals and plants. For example, frequent sampling activities may disturb the bottom mud and affect the habitat environment of aquatic organisms. Although simple automated devices reduce human interference, their installation and maintenance still need to enter the wetland interior, which has a certain impact on the ecological environment. In addition, some automated devices may generate noise or electromagnetic interference during operation, further affecting the balance of the wetland ecosystem.

[0030] Wetland water quality and soil monitoring sampling devices play an important role in wetland management and protection. Although existing monitoring devices meet the monitoring requirements to a certain extent, there are still problems such as low sampling efficiency, poor sampling accuracy, cumbersome data processing, and large ecological interference.
