For inconvenient emergency stop control with low reliability of existing electro-hydraulic control equipment of hydraulic support,an emergency stop control scheme for electro-hydraulic control system of hydraulic support was proposed which was based on C8051F020 single chip microcomputer.A transmission mode taking special RS485 bus as emergency stop signal channel was drawn up as well as concrete implementation scheme of interlocking of emergency stop and reset.Meanwhile,functions of fault location,fault diagnosis and power-off memory for emergency stop state of support controller were achieved by use of software.An electro-hydraulic control system of hydraulic support based on the emergency stop control scheme has run in a coal mine with good effect.
