Abstract: After applying embedded system based on ARM7 into mine-used flameproof feeding switch,real-time data collection and rapid connecting with industrial Ethernet of underground mine-used flameproof feeding switches were realized. Communication between ground monitoring station and underground monitoring system of feeding switches based on embedded system was realized by use of technology of the socket programming.Information inquiring and remote intelligent monitoring of feeding switches were realized with Web service platform based on B/S framework established by ASP.NET.Monitoring system for mine-used flameproof feeding switches based on embedded system improved level of operation and control of underground feeding switches,and also could be used for reference of design of intelligent remote monitoring system of other electric equipments of coal mine underground.
