In described step 3, early warning information processing enter (1.6) sends to Lightning Warning information release terminal (1.3) by the thunderstorm forecast information generating by Lightning Warning information promulgating platform (1.2), Lightning Warning information release terminal (1.3) broadcasts thunderstorm forecast information, reminds workmen.
6. Lightning Warning method according to claim 4, is characterized in that: in described step 2, establish early warning region-of-interest and take early warning region-of-interest as the center of circle, the region that radius is less than in 10 scopes is the 4th viewing area;
When the atmospheric electric field information in early warning region-of-interest is increased to 8kV/m, and thunder and lightning positioning information shows in the 4th viewing area has had thunder and lighting process to occur in the past in 2 hours, and during the trend that the oriented early warning region-of-interest in position that thunder and lighting process occurs moves, early warning information processing enter (1.6) generates sound and light alarm signal;
In described step 3, early warning information processing enter (1.6) sends to Lightning Warning information release terminal (1.3) by the sound and light alarm signal generating by Lightning Warning information promulgating platform (1.2), and Lightning Warning information release terminal (1.3) carries out sound and light alarm prompting to site operation personnel.
7. according to the Lightning Warning method described in claim 4 or 5, it is characterized in that: described yellow early warning information or orange early warning information or red early warning information or thunderstorm forecast information send to the mobile phone (1.12) in Lightning Warning information release terminal (1.3) by the cellphone information release module (1.9) in Lightning Warning information promulgating platform (1.2).
8. according to the Lightning Warning method described in claim 4 or 5, it is characterized in that: described yellow early warning information or orange early warning information or red early warning information or thunderstorm forecast information send to the computer (1.11) in Lightning Warning information release terminal (1.3) by the WEB information issuing module (1.7) in Lightning Warning information promulgating platform (1.2).
