Lightning current monitoring system is composed of lightning current monitoring recorder (field equipment) and monitoring management platform (background equipment) based on Ali Cloud; When lightning strikes on the floating roof tank, the lightning current will produce corresponding changes in magnetic field intensity, which will be picked up by the lightning current monitor (current sensor) in the lightning current recording transmitter, transmitted to the current acquisition module, and transmitted signals through the wireless transmission system to the control room monitoring platform to record and display data such as lightning strike time, lightning current intensity and lightning polarity, and implement monitoring and alarm. And realize linkage.
