Lightning Protection Company Electric Field Meter Warning Lightning Monitoring System
A. Introduction of atmospheric electric field meter system
Atmospheric electric field meter as the main instrument to detect
the intensity of the electric field in the atmosphere, plays an
important role in lightning monitoring and early warning, electric
field meter is a high-tech highly integrated atmospheric detection
equipment, divided into three parts: outdoor probe, instrument box
and indoor data processing display center. The probe detects the
change of atmospheric electric field, and the circuit in the
instrument case converts the detection result to analog-to-digital,
and packages it with time information, and transmits it to the
indoor host computer remotely through RS-485 serial port or
wireless GPRS.
Abstract
A lightning monitoring system is used to observe, collect and
analyse lightning activities so that a preventive measure to
protect power equipment from severe damage can be planned. An
effective lightning monitoring system is crucial to ensure the
reliability and sustainability of the electrical energy supply.
Despite numerous published papers on this topic, there seem to be
an absence of comprehensive review papers that evaluate monitoring
technologies and their performances. Owing to the literature gap,
this paper is written to summarise the working principles of the
relevant sensors and the various methods of data transmission,
storage and analysis, as well as the various ways of predicting the
occurrence of lightning strikes. This knowledge will contribute to
the development of a new online lightning detection system that
will be more efficient, without reducing the effectiveness and
sensitivity of the system, by utilizing the available technology
for data transmission and analysis.
Functional features
Central data processing station can connect with several probes through communication channel and offer location processing on the received return strokes in a real-time manner to provide precise location and intensity and other parameters of every return stroke, which will be stored, displayed, printed or copied into graphics by graphic display terminal at any time. Besides, central data processing stations can set the parameters of every probe and tune out the operating mode of every probe through communication system. Through the data service network or by setting several graphic display terminals, several departments can share the lightning information resources.
A variety of communication forms, such as WiFi, wired network, special line and satellite communication network.
Real-time data, sound continuity, quick speed of network arrangement low operating and maintenance cost, extensive coverage and wide application field.
High performance, reliability as well as integrity of recorded data
Complete set of power and signal measures
High fault tolerance, user-friendly interface, easy operation
Nationally unified data processing center stations provide data for comprehensive positioning.
