Farmland quality monitoring system
Cultivated land is the basic resource and condition for human survival. It is related to national food security and the livelihood of the people. The real-time online cultivated land quality monitoring system can not only guide farmers in precise fertilization to reduce production costs, but also provide important decision-making basis for soil remediation and improvement, as well as monitoring non-point source pollution.
Obtaining real-time parameters of soil CEC not only indirectly reflects the soil's fertilizer retention and supply performance, but also further obtains dynamic information on soil charge density, electric field strength, and electrostatic repulsion between soil particles, thereby indirectly obtaining information on the formation and stability of soil aggregates and understanding the dynamic situation of soil structural pores, Ultimately, it helps to understand the dynamic information of the four major fertility factors of soil "water, heat, air, and nutrients" (these four fertility factors and their relationships are soil fertility quality). Through the national and local multi-level linkage real-time monitoring platform for cultivated land quality, real-time collection and processing of soil, water, and fertilizer quality data can be carried out to construct macro cultivated land quality data for the whole province and even the whole country, and be centrally analyzed and displayed for precise fertilization, soil remediation, soil improvement, and non-point source pollution monitoring. Build an intelligent system that can conduct real-time online monitoring and regular evaluation to guide efficient and scientific land management.
Soil erosion monitoring system
China is one of the countries with the most severe soil erosion in the world, with a wide range and large amount of soil erosion. In 2021, the national soil erosion area reached 2.6742 million square kilometers. Severe soil erosion is a concentrated reflection of China's ecological deterioration, threatening national ecological security, drinking water safety, flood control safety, and food security. If real-time monitoring of soil erosion can be achieved, the level of soil erosion that has already occurred can be evaluated, the effectiveness of soil and water conservation measures can be judged, and risk warning can be provided for areas prone to soil erosion.
Real time online monitoring of soil CEC values can further obtain dynamic information on soil charge density, electric field strength, and electrostatic repulsion between soil particles. By combining the electrostatic repulsion between soil particles with various external forces of the soil during rainfall, such as raindrop impact, water impact shear force, and gravity, the risk of soil loss can be predicted and evaluated. By establishing a soil erosion monitoring system and combining external soil environmental data (meteorological, geological, etc.), visualization of the assessment and trend prediction of soil erosion status can be achieved, providing data support for departments such as water conservancy, natural resources, agriculture, and scientific research units.
Disaster risk warning system
In recent years, due to the influence of extreme weather, droughts, floods and other disasters have occurred frequently in various regions. Due to factors such as terrain, topography, and human engineering activities, landslide accidents have occurred frequently in some parts of China. Once a landslide occurs, it not only causes casualties and property damage on the landslide, but also endangers the safety of houses, transportation, and personnel within a certain range. Timely and effective monitoring of mountain conditions and early detection and warning of anomalies have become a focus of attention in response to the problems of difficult prevention, rescue, significant harm, and difficult governance of landslides.
The monitoring of landslide disasters at home and abroad mainly adopts five types of monitoring techniques: macroscopic geological observation method, simple observation method, station observation method, instrument observation method, and automatic remote sensing observation method. However, the common problem with these methods is that data collection requires manual intervention on site, which leads to a lack of real-time monitoring of landslides. The successful landslide prediction at home and abroad is basically achieved through displacement monitoring, with obvious lag. From the perspective of the micro field of soil, this system focuses on the core parameter of soil - "CEC". Through real-time online monitoring of soil CEC, it further obtains dynamic information on soil charge density, electric field strength, and electrostatic repulsion between soil particles. From the micro scale of soil particle interaction, it monitors the stability of mountain soil structure and mountain geological structure, and combines parameters such as mountain gravity and pressure to provide early warning for geological disasters. This system calculates real-time surface charge data through a data model based on real-time monitoring data such as soil pH, conductivity, moisture content, and soil temperature. It can analyze the real-time changes in static electricity, adsorption energy, composite binding energy, and aggregate stability of soil interactions under actual conditions. By combining meteorological data and conventional geological disaster monitoring techniques, early warning and prevention of geological disasters can be achieved.
The instrument has a wide range of applications, not only providing assistance for basic research in multiple disciplines, but also providing assistance for product development in many industrial fields.
