The lightning current monitoring system of claim 7, wherein the MCU module is further configured to: if the statistical database comprises historical lightning stroke state information which is the same as the monitoring position, the same in lightning current polarity and high in lightning stroke risk intensity, determining that the early warning level of the lightning stroke information is high-level early warning; if the statistical database comprises historical lightning stroke state information which is the same as the monitoring position, the same in lightning current polarity and low in lightning stroke risk intensity, determining that the early warning level of the lightning stroke information is middle-level early warning; and if the statistical database comprises historical lightning stroke state information which is the same as the monitoring position, has different lightning current polarities and has low risk intensity, determining that the early warning level of the lightning stroke information is low-level early warning.
9. A lightning current monitoring method, comprising:
acquiring lightning stroke pulse current on the surface of an object to be detected, and generating a standard lightning signal according to the lightning stroke pulse current;
receiving the standard lightning signal, and generating a wake-up instruction according to the standard lightning signal;
receiving the standard lightning signal and temporarily storing the standard lightning signal;
receiving the awakening instruction, finishing starting according to the awakening instruction, acquiring the temporarily stored standard lightning signal, acquiring lightning stroke information included in the standard lightning signal and judging whether the lightning stroke information is non-false triggering information or not;
and if the lightning stroke information is non-false triggering information, uploading the lightning stroke information to a lightning protection supervision intelligent cloud platform.
10. The lightning current monitoring method according to claim 9, wherein the step of obtaining lightning strike information included in the standard lightning signal and determining whether the lightning strike information is non-false triggering information comprises:
and acquiring a lightning current peak value included in the lightning stroke information, judging whether the lightning current peak value is greater than a preset peak value threshold value, if not, determining that the lightning stroke information is false triggering information, and if so, determining that the lightning stroke information is non-false triggering information.
