Embodiment Construction
[0011] Below in conjunction with specific embodiment the present invention is described in further detail:
[0012] According to the lightning situation within the monitoring range, the atmospheric electric field meter can give the corresponding level of lightning warning level. However, for the situation where the initial warning of lightning is approaching but the warning is not reached, under normal circumstances, the warning cannot be triggered until the signal rises above the threshold, which delays the warning time. The invention aims at the critical lightning early warning state of the atmospheric electric field meter, so that it has a reliable early warning capability.
[0013] According to the actual situation of the atmospheric electric field, the atmospheric electric field instrument will send out (w 1 ,w 2 ,w 3 ,...,w k )k levels of lightning warning, there is w 1 2 k . Only when the electric field meter detects a signal exceeding the intensity of γ can the i...

The invention relates to a method for improving the thunder and lightning early-warning capability of a single atmospheric electric field instrument, and the method comprises the steps: 1, finding out atmospheric electric field instruments which exceed 85% of a gamma value; 2, searching atmospheric electric field instruments, which are higher than or equal to the first thunder and lightning early-warning level, in a detection range of the atmospheric electric field instrument A for the atmospheric electric field instrument A, and obtaining an atmospheric electric field instrument set S1 meeting the conditions; 3, searching other atmospheric electric field instruments, which are higher than or equal to the first thunder and lightning early-warning level, in a detection range of the atmospheric electric field instrument S1i, and obtaining another atmospheric electric field instrument set S2 meeting the conditions; 4, continuing to complete the traversal of atmospheric electric field instruments at all levels; 5, enabling the above searched atmospheric electric field instruments to form a set J1, enabling the atmospheric electric field instruments in the set J1 to arranged from the near to the far according to the sequence of distances between the atmospheric electric field instruments and the atmospheric electric field instrument A, and adjusting the thunder and lightning early-warning level of the atmospheric electric field instrument A to be the first thunder and lightning early-warning level if the early-warning levels of the atmospheric electric field instruments in the sequence do not decrease progressively and the number of atmospheric electric field instruments in the set J1 is greater than epsilon.
Description
technical field [0001] The invention relates to the technical field of lightning early warning, in particular to a method for improving the lightning early warning capability of a single atmospheric electric field instrument. Background technique [0002] Atmospheric electric field meter is the main lightning warning device. When lightning occurs, the ground electric field strength changes. The atmospheric electric field instrument uses the magnitude of the induced charge induced by the energized conductor to continuously rotate in the atmospheric electric field to detect the atmospheric electric field strength, thereby warning the generation of lightning. Atmospheric electric field meters are usually deployed in a networked manner. In order to improve the timeliness of lightning early warning, many patents propose their own solutions, for example: the utility model patent with the publication number CN204143600U titled "A Field Lightning Alarm Device Based on Atmospheric E...
