When exploration of the deep electrical structure of the earth's crust and mantle scale is conducted. LEMI-417 long-period magnetotelluric sounding instrument is a prevailing system for continuously observing natural electromagnetic field. In this paper, through in-depth study of the original binary data structure of the system, the authors analyzed the corresponding data structure in C++ computer language and also listed the core program code so as to provide necessary support for researchers who are engaged in the research on deep earth exploration and signal processing in electromagnetic field.
