Background Introduction

The IoT ecological monitoring technology of Beijing Huayirui Technology Co., Ltd. is becoming increasingly mature, and its emergence has overturned traditional ecological monitoring concepts. Make ecological monitoring more intelligent, real-time, networked, and digitized. More adaptable to new scientific research needs, the application of big data processing and cloud platforms has increased the sharing and conversion of scientific research achievements, greatly promoting the development of ecological monitoring networks.

System architecture and main features

lThe use of digital intelligent sensors;

lNo analog signal loss, especially for microvolt signals;

lReduce cable layout and facilitate installation and maintenance;

lReal time data sharing and viewing are simple and convenient

Introduction to Typical Application Cases

1) Ministry of Agriculture Discipline Group Internet of Things (Chinese Academy of Agricultural Sciences and various research institutes)

This project will be constructed in multiple phases, including our company's expertise in vortex related flux stations, agricultural gas evapotranspiration systems, phenological systems, soil moisture conditions, as well as the integration of monitoring instruments from other manufacturers30 provinces, autonomous regions, municipalities directly under the central government.

2) Super gradient weather station (newly designed system)

Traditional gradient stations are composed of multiple layers of sensors, mostly analog sensors, with different cable lengths, which increases the difficulty of deployment and cannot guarantee the consistency of measurement precision of each layer of sensors, requiring high precision for data acquisition systems.

The application of Internet of Things technology in gradient weather stations has solved the above problems. In the new design, the intelligent sensor and wireless node mode are uniformly selected, without considering the layout of cables. The installation is simple, maintenance is convenient, signal transmission is stable, and all sensor measurement data can be measured and recorded simultaneously.

3）Urban Heat Island Effect Monitoring System (Beijing Institute of Urban Meteorology, China Meteorological Administration)

Co designMore than 80 temperature and humidity monitoring nodes are distributed in representative locations in a certain area of the city, and all data is transmitted to the data center through wireless networks.

4）Tanggula Frozen Circle Snow Gauge Monitoring Network (Northwest Research Institute, Chinese Academy of Sciences)

share1Two monitoring nodes are located in the Tanggula area of the Qinghai Tibet Plateau, which belongs to the high-altitude and cold zone. All instruments have withstood the severe test of harsh environments such as low temperature and low pressure.

The arrival of the Internet of ThingsThe era of sensorsIn the era of artificial intelligence

The Internet of Things has been around for many years and is difficult to popularize in ecological monitoring. The main reasons are the need to be familiar with and unify the protocols of various manufacturers, as well as to match and solve the problems between different layers of network communication. Beijing Huayirui Technology Co., Ltd. serves the ecological monitoring industryOver the course of 15 years, I have accumulated a wealth of experience and technology, and have rich experience and case studies in the combination of network interfaces, communication protocols, and network layering for various products. Reliable solutions to the following issues:

lUnified analysis of agreements among manufacturers(Application layer)

lUnified solution for device connection and ensuring reliability (physical layer and link layer)

lReliable, stable and progressiveness (transport layer, network layer, application layer)
