DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Please refer to Figures 1 to 5 , a single station lightning location system, including the first support rod 2 fixed on the ground, the first support rod 2 upper end detachably provided with the cross 12, four ends of the cross 12 are respectively installed with the atmospheric electric field instrument 13, the direction sensor 14, the meteorological element sensor 15 and the secondary antenna 16 in communication connection with the main control board, the upper end of the middle part of the cross 12 is detachably installed with the primary antenna 17 in communication connection with the main control board.

[0030] Before lightning occurs, the electric field in the atmosphere will change significantly, and the atmospheric electric field instrument 13 can monitor these changes to predict the possibility of lightning. When the electric field strength exceeds the threshold value, other devices are triggered to enter the working state, and the direction sensor 14 is used to determine the direction of the lightning. In combination with the signals received by the antenna, the direction is calculated by the time difference or phase difference of arrival. For example, a baseline is formed by using a primary antenna 17 and a secondary antenna 16, and the azimuth angle is determined by measuring the time difference of signal arrival. The meteorological element sensor 15 is used to measure meteorological parameters such as temperature, humidity, air pressure, wind speed, etc. in the atmosphere. These data are used to correct the accuracy of lightning positioning, because the weather conditions can affect the signal propagation speed or path. For example, changes in temperature and humidity can affect the dielectric constant of the air, thereby affecting the propagation speed of electromagnetic waves, and in turn affecting the accuracy of time difference calculation. The secondary antenna 16 and the primary antenna 17 are used to receive electromagnetic signals generated by lightning. Lightning produces a wide band of electromagnetic pulses, and after the antenna receives these signals, the position of the lightning can be determined through processing.

[0031] Working principle: The atmospheric electric field instrument 13 continuously monitors the change of electric field. When the electric field strength increases suddenly indicating the occurrence of lightning, the system enters a high sensitivity mode and transmits the signal to the main control board. The main control board controls the direction sensor 14 and the meteorological element sensor 15 to collect signals;

[0032] Among them, the meteorological element sensor 15 is used to record environmental parameters for subsequent signal propagation speed correction, such as humidity affecting the speed of electromagnetic waves.

[0033] Among them, the primary antenna 17 and the secondary antenna 16 are always in a signal receiving state, used to receive electromagnetic pulses of the same lightning and send signals to the main control board. The main control board calculates the time difference TDOA or phase difference of signal arrival at the two antennas, combines the baseline length of the antenna spacing, and determines the azimuth angle of the lightning using geometric relationships. The direction sensor 14 provides the azimuth angle of the device itself, such as the installation angle of the device, to ensure that the calculated lightning direction is based on the geographic coordinate system. As for how to calculate, there are relatively mature systems in the prior art, and the connection of the circuit is not drawn in the drawings of the present application, and the prior art is also relatively mature. Users can adaptively set in different positions, and the present application will not be described in detail.
