[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", and "connected" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, or an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The key technologies of lightning detection and location technology include lightning signal detection technology, lightning signal data collection technology, lightning type identification technology, network communication technology, lightning location algorithm and UI presentation technology. The detection of lightning signals is the key and foundation. The formation of lightning is a complex process. The first is the accumulation of charges in the cloud: when water droplets and ice crystals in the cloud collide with each other, static charges are generated. Usually, positive charges accumulate in the upper part of the cloud, while negative charges accumulate in the lower part. As the charges accumulate, the charges in the cloud begin to separate. Positive charges move upward and negative charges move downward. When the charges separate, an electric field is formed. The intensity of the electric field increases with the accumulation of charges. When the intensity of the electric field reaches a certain level, a discharge channel is formed. The discharge channel refers to the air molecules in the cloud being heated and ionized by the electric field to form a conductive channel. When the discharge channel is formed, the charges will flow rapidly along the channel to form lightning. The temperature of lightning can reach up to 30,000 degrees Celsius, which is much higher than the temperature on the surface of the sun. The discharge process of lightning is very fast, ranging from a few microseconds to a few milliseconds, or even tens of milliseconds. The energy of lightning is released as light and heat, forming the lightning we see.

[0023] The formation of lightning is a complex process involving several steps, including charge accumulation in the atmosphere, charge separation, electric field formation, discharge channel formation, and lightning formation. The formation of lightning can be compared to a parallel circuit of several capacitors with different withstand voltages or to a capacitor with a dynamic withstand voltage value.

[0024] When the charge gradually accumulates on the capacitor plates, the voltage between the two electrodes will gradually increase. First, the capacitor with low withstand voltage will break down, which means the initial discharge or initial lightning will form, causing the medium (atmosphere) between the plates to ionize, changing the insulation properties of the atmosphere, reducing the insulation performance, and thus reducing the withstand voltage performance of the capacitor. When the charge further accumulates on the plates, the capacitor will further break down, repeating this process until the energy is consumed, completing the entire life cycle of a lightning from preparation to formation to termination. Therefore, we will detect lightning signals in the form of various pulse trains.

[0025] The present invention collects electromagnetic signals from a distant lightning radiation source, identifies the type of lightning by amplifying and filtering, and analyzes waveform characteristics, and calculates and measures the time and position of lightning occurrence through data processing.
