ENVIDATA Ecological Environment Internet of Things System
1 Introduction
The Earth's biosphere is a continuous and dynamically changing system. The impact of economic activities in agriculture, forestry, water conservancy, and environmental protection on the earth's environment is interactive. Global climate change has become a topic of common concern in all fields. How to monitor the occurrence and development of ecological environment changes in real time, continuously and automatically becomes a challenge faced by researchers and managers in various fields.
2 System design
2.1 Objective
The ENVIdata eco-environment Internet of Things system integrates global high-quality measuring instruments for measuring soil, plants, and the environment, the latest data collection platform and communication technology outside the United Nations, and the industry ’s first Internet eco-environment data management system. The system automatically and continuously observes the soil, plants, atmospheric continuum, surface water environment and groundwater environment, and can directly transmit data to the (China Ecological Environment Internet of Things) website or a website designated by the user. Time series changes and correlation analysis to determine the state development of the monitored objects. It can be used for scientific research, such as monitoring records of conventional environmental factors of terrestrial ecosystems and water ecosystems, and can also serve economic activities and daily management in fields such as agriculture, water conservancy, meteorology, and environmental protection, such as moisture forecast, irrigation forecast, and water resources. Management, water supply network monitoring, sewage discharge, etc.
2.2 Layout of the system
The ENVIdata ecological environment IoT system consists of a field station and a central server. The locations of field stations should be representative of the research objects, such as the water environment, soil environment, atmospheric environment, and biological environment of the ecosystem. The data logger uses the data push mode to send the recorded data from the field to the server. This new design is more stable, more reliable, and cheaper than the traditional phone cat to send data to the server.
The ENVIdata central server can be deployed in an ecological environment monitoring station to realize networked dynamic observation of single-station process research; it can also be installed in a remote data monitoring center to complete regional comprehensive observation and cross-scale ecological simulation.
2.3 Data collection
The data collection frequency of the field station is set according to research needs, ranging from 10 times per second, minutes, and hours. The ecological environment data is sent to the ENVIdata central server or website at various intervals (minutes, hours, and days).
As long as users can access the Internet, they can browse real-time data. The ENVIdata system allows users to set up various alarm conditions, and over-limit data can be sent to users via email or SMS. Users can customize the data sent by email.
Central server Chinese interface, easy to operate and manage, providing multi-parameter, real-time or historical data curve graph
2.4 Observation indicators
The parameters observed by the ENVIdata Eco-Environment Internet of Things system cover important ecological processes of various ecosystem types, such as:
Soil: soil moisture, soil temperature, salinity, water holding capacity, soil gas
Plants / crops: temperature, height, stem changes, water consumption
Meteorology: rainfall, temperature, humidity, wind speed, wind direction, air pressure, evaporation, radiation, spectrum
Water ecology: water level, temperature, conductivity (TDS, total salt, density), dissolved oxygen, pH, nitrate, redox potential, turbidity (TSS), chlorophyll, rhodamine, blue-green algae, nitrate, 17 parameters including fluoride, chloride, potassium ion, ammonia ion, sodium ion and calcium ion
Hydrology: water level, flow velocity, groundwater quality, surface runoff
3 Data processing
The ENVIdata Eco-Environmental Internet of Things system not only manages real-time and remote collection of data from field stations, such as weather stations, water level stations, surface runoff, plant flow monitoring systems, and erosion systems, etc. It is a different scale for research plots, landscapes, regions, etc. The ecosystem provides basic data with high spatial and temporal resolution. It can also dynamically and digitally manage the basic information of the ecological station ’s geographic resources, scientific researchers, projects, and equipment. It also provides a data management module for field sampling and surveys, which facilitates scientific researchers ’ Data classification management and sharing of long-term large plots, phenology, litter, coarse wood residues, soil microorganisms, animal resources, health and service function evaluation.
4 Application case
Irrigation forecast
Through real-time remote telemetry of moisture, rainfall, farmland microclimate information, comprehensive engineering, agronomy, management and other water-saving measures, based on weather forecast data, soil structure, crop growth period, combined with water supply, scientific prediction and forecast of different soil types and different plantings Structure, dynamic conditions of farmland water under different water supply conditions, giving suitable irrigation time and suitable irrigation volume, real-time tracking of soil moisture changes, timely adjustment of forecast results, and the ability to regularly issue forecast results to farmers through the website to guide farmers in time , Appropriate irrigation, realize scientific irrigation, water-saving irrigation
The field data of ENVIdata moisture monitoring and irrigation forecast system can be analyzed by irrigation forecast software. Irrigation forecast software has been used at home and abroad for nearly two decades.
Water balance study
Selection of parameters such as rainfall, soil moisture, water level, evaporation, etc., can be used to study the water balance of single plot, farmland, irrigation pit experimental field, and can also be used to compare the evapotranspiration of different ecosystems in the region, providing reasonable allocation and utilization of water resources Real-time data support.
Energy balance research
Energy balance research is the basis for studying the material productivity of the Earth ’s biosphere. By measuring the solar radiation, soil temperature, heat flux and other parameters of a single measurement point or different measurement points in a region, the energy budget of a single point or region is calculated. Global climate change research provides basic data.
Bloom forecast
The aquatic ecological sensor can comprehensively reflect the growth status of phytoplankton in the water environment. The multi-point layout and remote data transmission of field stations are used to monitor the occurrence and development of harmful algae in real time. Important tool.
Application situation at home and abroad:
Australian farms, wine vineyards in California, sugar cane plantations in Switzerland, apple orchards in South Africa, vegetable plantations in Kenya, Xinjiang Construction Corps has adopted the system ’s irrigation forecast module in the irrigation management of cotton to study the water absorption patterns of root systems and Water Consumption.
The Chinese Academy of Sciences Ecological Research Network, the Forest Ecosystem Field Positioning Research Station, the Academy of Agricultural Sciences, the Academy of Forestry, the Academy of Water Sciences, and the National 973 Project use the field soil, plant, and meteorological monitoring units of the system to conduct water balance and energy balance studies.
The Daxing Experimental Base of the Chinese Academy of Water Sciences uses a complete soil moisture, temperature, and conductivity measurement system to transmit data to the website in real time. As long as users can access the Internet, they can collect and view data on the website at any time.
