英文摘要：

Designed the hardware of main station and sub--station for electromagnetic detection system. Combined with wireless sensor network topology and routing algorithm, Distributed electromagnetic detection net is constructed. Using IAR EW430 integrated environment to design the program of sub--station and main station, and using LabVIEW virtual instrument development environment to design the soft- ware PC. Through wireless data transmission technology to solve the difficult problem of prototyping of the electromagnetic exploration field effectively, so improving the efficiency of field work significantly. Experiments show that compared to foreign instruments this system has the similar performance.
