The invention relates to a portable
thunder and
lightning early warning device which comprises a rod body, an
electric field sensor detachably installed at the top end of the rod body, a photovoltaicpanel
assembly detachably installed on the rod body and a control box, and the photovoltaic panel
assembly and the control box are both installed on the rod body through an installation block with a rapid connection structure. The installation position of the installation block on the rod body is adjustable, and the
pitch angle of the photovoltaic panel
assembly is adjusted through the installation position of the installation block; the
thunder and
lightning early warning system comprises the portable
thunder and
lightning early warning device; a communication controller, a photovoltaic controller, a
lithium battery and a wiring terminal strip are arranged in a control box; an audible and visual alarm is arranged on the upper side of the control box, and a power switch, an alarm switch, anetwork cable interface and at least three
aviation plug interfaces are installed on the lower side face of the control box. The thunder and lightning early warning method comprises the following steps: grading thunder and lightning conditions according to
electric field intensity detected by the thunder and lightning early warning device and the thunder and lightning
early warning system; the portable thunder early warning device and
system have the advantages of being convenient to disassemble and assemble on site and capable of conducting different levels of lightning early-warning.
