Abstract With the rapid development of human society and the surge of engineering construction, the disturbance of the geological environment has grown substantial. The influence of extreme climatic factors and the frequency of geological disasters have increased. Landslide is an important geological disaster. The foundational research in geological disaster detection or monitoring involves studying the physical phenomena associated with the occurrence of landslides, analyzing their signal characteristics, and indirectly determining their development and changes. This scientific area is worthy of in-depth exploration. However, research on the key design and specific implementation of electromagnetic instruments tailored for landslide detection remains lacking. This study is based on the interdisciplinary theoretical system of electronic circuits, embedded computer science, digital signal processing technology, geophysics, and engineering geology. It independently develops a functional prototype of an electromagnetic detector for landslide detection. This design combines the current level of development of electronic disciplines and applies the embedded multicore Da Vinci industrial-grade computer system in the field of earth detection instruments. This study then designs and implements a landslide detection system with independent intellectual property rights.
