Embodiment Construction

[0036] The preferred embodiments of the invention will be further described in detail below.

[0037] Such as image 3 As shown, a schematic diagram of an embodiment of a residential lightning monitoring and positioning method. In this embodiment, a self-made lightning current sensor is used, and its response characteristics are calibrated in the laboratory to obtain the relationship between the output voltage, the current amplitude, and the measurement distance. , by using three lightning current sensors at different positions, the lightning current amplitude and plane coordinates can be obtained by solving the equations for three sets of measurement data obtained from the same lightning current. The lightning current sensor can use air-core coils, and the three coils are placed on the edge of the measured area in the same direction. The angle between the axes of the air-core coils is 120° to ensure that the entire measurement system has a high degree of lightning current at ...

Abstract

A small-region lightning monitoring and positioning method and system. The method comprises the following steps: S1, performing experimental calibration on a function relationship of an output voltage peak value of a lightning current sensor during lightning, a lightning current peak value and a lightning stroke point; S2, setting, within a measured cell, three lightning current sensors; and S3, respectively detecting output voltage peak values of the three lightning current sensors during lightning, and jointly determining the position of the lightning stroke point according to the function relationship.

Description

【Technical field】 [0001] The invention relates to a small-area lightning monitoring and positioning method and system. 【Background technique】 [0002] Lightning location and lightning current parameter monitoring play an important role in the study of lightning characteristics and lightning protection. The lightning location system can provide more technical information for lightning protection, meteorological research, construction and other fields. At present, there are relatively mature lightning monitoring networks all over the world. By monitoring the direction of the magnetic field generated by the lightning current and the time it reaches the sensor, parameters such as the location of the lightning strike, the amplitude of the lightning current, and the polarity of the lightning current can be calculated. The positioning methods of lightning positioning are mainly divided into single-station positioning and multi-station positioning. The more widely used one is multi...
