Abstract: Aiming at the shortcomings of the coal mine protection safety, this paper designs a feeder protection system based on dsPIC30F6014A, with the function of gas, wind power, over voltage, short circuit, and leakage current protection, communication option, and an external remote shunt release button, which not only implements integrated data acquisition and fault handling, but also lowers the design cost. The feeder protection system greatly improves the coal mine production safety with high precision and stable work.
