Research on dual-core low-voltage feeder switch control system based on DSP and ARM

This research applied DSP and ARM to construct coal mine low-voltage feeder switch control system. It realized the real-time fast diagnosis and protection control of feedback cycle´s short-circuit, breakers, overload, leakage, over-voltage etc by DSP and read three phase voltages and phase currents through HPI by ARM. Not only this, it also made use of Ethernet interface , embedded TCP/IP suites and SOCKET program method to realize the information exchange between ARM and remote monitoring Host ,and finally it accomplished intellectual monitoring of coal mine low-voltage feeder switch.
