Soil Erosion Monitoring System

1.Product overview of Soil Erosion Monitoring System

Soil Erosion Monitoring System is a useful tool in the fight against soil erosion to obtain information about conditions that favor or hinder soil erosion.In our water conservation experiments, whether it is measuring data from runoff fields or small watershed soil erosion, a lot of manual work will occur, which causes many work inconveniences.After the research and development of our company's FT-LS1 type soil erosion automatic monitoring device product, it replaced a lot of manual work.After years of experiments and use results, the flow error is within 3%.The error of silt content is less than 5%, and the performance and appearance of the product have been updated for a long time and have made great progress.

The automatic soil erosion monitoring system is mainly composed of a data acquisition and storage master, sand content measurement sensor, surface flow sensor component, and rain sensor.The rainfall intensity and its changes over time and the total rainfall and rainfall duration are measured by the rainfall sensor.The surface flow sensor component automatically measures the surface flow, and calculates the surface runoff flow that changes over time through the central control computer software and parameter settings to obtain the real-time change of runoff flow.In the system design, the sand content measurement sensor is used to measure the runoff sand content in real time according to the characteristics of rainfall/runflow changes.

Through the work management/data storage software and the main control and control, the process data of sediment content, runoff and rainfall measured by each sensor are managed and stored, and the measurement data is remotely transmitted to the management and monitoring center.

2.Product features of Soil Erosion Monitoring System

1.Unattended all-weather, automatic measurement and storage: runoff, runoff sand content, sand transport capacity

2.Power supply: Real-time data automatic collection and storage can be powered off for 7 days

3.The automatic soil erosion monitoring station work management data acquisition and storage master can store a large amount of data locally, and can download data through the RS232 interface on site; or transmit data to the management center via wireless when there is a remote request.

4.Solar power supply, the normal state is power-saving and dormant when there is no rainfall or runoff.

5.It has the function of real-time online monitoring and displaying dynamic processes and curves and historical data download on computer software.

6.The sampling frequency and adjustment clock can be set freely on the data management master

7.The central control computer software can draw runoff, sediment content, rainfall, scene, runoff, seepage, soil erosion, etc.based on the collected data.

3.Soil Erosion Monitoring System Sensor Work Instructions

1.Working process of silt and sand content sensor

The surface water body enters the pipeline from A1, flows out through A2 and pushes the flow sensor.Some water body is discharged from A3.Processor C calculates the real-time flow based on the flow rate obtained by the flow sensor.B1 collects the surface water body and is sent to the weighing sensor.Sensor D sends the collected data to processor C to obtain the sediment content after processing.After obtaining the data, sensor D discharges the internal sample from B2 to prepare for the next sampling.Processor C outputs external devices through 485 or serial port.
