Automatic monitoring system for soil erosion

Automatic monitoring system for soil erosionIt is a comprehensive system that integrates modern sensors, data acquisition and processing, data analysis and early warning technology, which can monitor key parameters of soil erosion in real time and accurately, providing scientific basis for soil and water conservation, ecological restoration and agricultural engineering. The system can monitor key parameters of soil erosion in real-time around the clock, and through data analysis and warning technology, automatically identify patterns and trends of soil erosion, predict potential soil erosion risks, and generate detailed reports and warning information.

1、 Product Introduction

In the monitoring of soil erosion in runoff fields and small watersheds, traditional manual measurement of flow and sediment data has the problems of large workload and low efficiency, as well as high labor costs and large data errors. After years of technological breakthroughs and extensive field experiments, the system has successfully innovated the traditional manual monitoring mode.

Automatic monitoring system for soil erosionIt consists of a data collection main control machine, sediment concentration measurement sensor, open channel flow sensor, and rainfall sensor. Among them, the open channel flow sensor component can automatically measure the runoff flow and accurately calculate the total runoff and instantaneous runoff data at different time periods through the controller; The sediment concentration measurement sensor collects real-time sediment concentration data based on the characteristics of runoff changes at sediment measurement ports with vertical distribution of runoff; The rainfall sensor is responsible for accurately obtaining cumulative rainfall data. The collaborative operation of various sensors and the collected data have critical value for soil erosion analysis.

The system uploads real-time sediment content, runoff, and accumulated rainfall data collected by various sensors to the cloud platform, making it easy for users to access, analyze, and manage data anytime and anywhere, providing scientific and accurate data support for soil and water conservation decisions.

Workflow of sediment content sensor: Surface water enters an open channel or Bacher trough through a water diversion channel and passes through an open channel flowmeter to obtain instantaneous runoff data, and calculates the total runoff per unit time. The surface water is collected by a water diversion pipe and sent to the main water tank. When the surface water capacity of the main water tank is sufficient for detection, the system starts and sends the surface water to be measured to the sample bin for detection. The sensor sends the collected data to the processor for processing to obtain sediment content. After obtaining the data, the sensor discharges the internal sample through the drainage pipe to prepare for the next sampling. The processor outputs to external devices through 485.

5、 Maintenance and upkeep
Please loosen the transport fixing rod before initial use, otherwise the equipment will not work properly.
When using it for the first time or for a long time without reusing it, please perform water calibration and zero calibration again.
Regularly check the water storage tank. If there is a large amount of sludge deposition or debris, please remove it. Remove the drainage valve and rinse it clean.
Regularly check the drainage valve, sample bucket inlet valve, sample bucket drain valve, and whether the water flow is unobstructed. If the water flow is weak or blocked, the control line on the drain valve can be removed and the drain valve can be disassembled for cleaning, and then reinstalled.
Keep the interior of the device clean, prohibit the accumulation of items in the weighing section, and prohibit the placement of items under the sample bucket.
When the temperature in the area where the equipment is located drops below zero, please drain the water inside the equipment and place it in a place where it freezes and damages the equipment.
When the sensor has been used for a long time and measurement errors occur, calibration and correction can be carried out by cooperating with the instrument. If the above methods of maintenance and upkeep still cannot calibrate and measure the sensor, it indicates that the sensor has been damaged.
