Design of Automatic Control and Protection System of Emulsion Pump-station of Coal Mine Based on Single-chip Microcomputer

This paper described the structure and working principle of a automatic control and protection system of emulsion pump-station of coal mine based on singlechip microcomputer. The system is(composed) with kinds of sensors, took P87LPC768 single-chip microcomputer as control chip and realized automatic control and protection for pump-station.The whole system is easy to achieve in the practical project.
