3D Lightning Positioning Vertical Observation System

The three-dimensional lightning location and observation system (ENTLS for short, all-flash detection system for short) produced by Earth Networks in the United States is currently the most advanced detection system in the world to detect the intensity, direction, frequency and changes of lightning. Composed of multiple lightning probes, the Total Flash Detection System is a meteorological measurement instrument designed and built on a compact unit utilizing state-of-the-art electronics and components to track and measure ground-to-ground (CG) lightning in the atmosphere and Cloud Flash (IC).
The probe of the all-flash detection system is a broadband system with detection frequencies ranging from 1Hz to 12MHz. When lightning occurs in the atmosphere, electromagnetic waves are generated and detected by the device. The wide frequency range allows the probe to detect not only strong ground-to-ground (CG) lightning strikes, but also weak cloud-flash (IC) pulses. The probe can record the entire waveform of each lightning, and then send it back to the central server in the form of compressed data packets, so as to complete the monitoring task of lightning.

方案构成

The three-dimensional lightning positioning observation system mainly includes lightning positioning monitoring station, management display and control center station and networking software. The lightning positioning monitoring station is deployed in the field. Through Ethernet and 4G wireless communication, the lightning original data and working status signals are sent to the management display and control center station, and the redundant dual-channel mode of wired network and wireless communication is used to ensure the communication. reliability.

方案特点

easy to deploy

Self-contained lightning system that designs and installs state-of-the-art electronics and components in a compact unit that can be deployed in any geographic location and accessed via a network
Complete Waveform Probing

Generally, lightning manufacturers can only provide lightning peak time and some waveform parameters. EN All Flash can record and archive complete waveforms for lightning detection, which greatly improves the detection efficiency of lightning.
Excellent performance

Using the time-of-arrival method to adopt adaptive digital filtering in the frequency range of 1Hz to 12MHz, the long-distance broadband sensor can obtain the highest all-flash detection efficiency
high degree of automation

The probe adopts adaptive digital filtering technology, which can reduce local noise, compact and precise structure, simple installation, small operation and maintenance
Advanced storm identification and tracking technology

Dangerous Thunderstorm Warning and Pulse Radar visualizations can be enabled to provide advanced advance warning of severe weather
visualization software

Earth Network Total Lightning Visualization (ENTLV) is a comprehensive web-based lightning visualization and modeling tool that provides access to real-time lightning data, as well as severe weather forecasting and monitoring. And provides advanced analysis functions and data display of the lightning location network, including key parameter data such as: peak current and polarity, classification, time and location and historical data calls

应用领域

The three-dimensional lightning positioning vertical observation system can be used in lightning monitoring, forest fire prevention, lightning protection and disaster mitigation, weather modification and other fields. It can also provide data support and basis for typhoon monitoring and tracking, thunderstorm warning and monitoring, and squall line research.

典型案例

The Beijing Meteorological Bureau has built a three-dimensional lightning positioning observation system, and has drawn up the installation locations of 10 lightning monitoring stations according to the terrain and environmental characteristics and the distribution of the Winter Olympic venues. The sites include 8 sites in Beijing and 2 sites in Tianjin. The stations are located in: Pinggu, Shangdianzi, Tanghekou, Foyeding, Dongmenying, Changping, Zhangfang, Zhaitang, Baodi and Wuqing. Through Ethernet TCP/IP communication, the lightning detection data of each sub-station is sent back to the server located in the Beijing Meteorological Bureau for analysis and storage.
