The invention discloses a lightning intensity measuring device and method. The lightning intensity measuring device comprises an alternating power supply, a planar antenna, an induction coil, a filter circuit, a broadband conditioning amplifying circuit, a sampling circuit, an FPGA kernel and a VGA information display module; the planar antenna comprises two copper plates which are parallel to each other, are horizontally arranged and are used for receiving changing electric field signals; the induction coil collects a magnetic field signal generated by the variable electric field and then outputs a tiny voltage signal; and the induction coil is sequentially connected with the filter circuit, the broadband conditioning amplification circuit and the sampling circuit and is used for inputting a voltage signal subjected to high-frequency component filtering and amplification into the sampling circuit for acquisition, transmitting the sampled voltage signal into the FPGA kernel for processing and displaying proce
