Soil Erosion Monitoring System

1.Soil Erosion Monitoring System Product Overview

Soil Erosion Monitoring System can automatically monitor, store and transmit the spatio-temporal changes of runoff and sediment content at each monitoring point.In our water conservation experiments, whether measuring the runoff field or the soil erosion data of small watersheds, there will be a lot of manual work, which causes a lot of inconvenience in the work. After the successful development of our company's FT-LS1 automatic soil erosion monitoring instrument, a lot of manual work has been replaced. After years of experiments and use, the error of flow is within 3%. The error of sediment content is within 5%. The performance and appearance of the product have been updated for a long time and have made great progress.

The automatic monitoring system for soil erosion is mainly composed of a data acquisition and storage host computer, a sediment content measurement sensor, a surface flow sensor assembly, and a rainfall sensor. The rainfall sensor measures the rainfall intensity and its changes over time, as well as the total rainfall and rainfall duration. The surface flow sensor assembly automatically measures the surface flow, calculates the surface runoff flow that changes over time through the central control computer software and parameter settings, and obtains the real-time change process of the runoff flow. In the system design, the sediment content measurement sensor measures the runoff sediment content in real time at the sediment measurement port vertically distributed in the runoff according to the rainfall/runoff change characteristics.

The work management/data storage software and the main control computer are used to control and manage the process data of sediment content, runoff and rainfall measured by each sensor, store the data, and remotely transmit the measurement data to the management and monitoring center.

2. Soil Erosion Monitoring System Product Features

1. Unattended around the clock, automatic measurement and storage: runoff, runoff sand content, and sand transport volume

2. Power supply: Real-time data is automatically collected and stored, and can work for 7 days without power supply

3. The main control computer for data collection and storage of automatic soil and water loss monitoring station can store a large amount of data locally, and can download data on site through the RS232 interface; or transmit data to the management center wirelessly when there is a remote request.

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

5. It has the function of online real-time monitoring on computer software, displaying the dynamic process and curve of each measurement parameter, and downloading historical data

6. The sampling frequency and clock can be freely set on the data management host computer on site

7. The central control computer software can draw runoff, sediment content, rainfall, number of events, runoff, infiltration, soil erosion, etc. based on the collected data.

3. Soil Erosion Monitoring System Sensor Working Description

1. Sediment content sensor working process

Surface water enters the pipeline from A1, flows out through A2 and pushes the flow sensor, and part of the water is discharged from A3. Processor C calculates the real-time flow rate based on the flow rate obtained by the flow sensor. B1 collects the surface water and sends it to the weighing sensor. Sensor D sends the collected data to processor C for processing to obtain the sediment content. 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.
