Abstract: We designed a set of remote monitoring system for disaster and environment of surface mine based on Cortex-M3 embedded processor. The system builds hardware platform and designs upper computer software of remote monitoring center according to modular design. The system can achieve data acquisition, local-storage, remote communication, wireless transmission and data statistics of all kinds of sensors at the scene by testing. The system provides a new design idea and reference solution for remote monitoring of field complex environment in mountain area, mine slope.
