Abstract: Base on security dependability and realize the automatic control of floodgate, the
traditional headstock gear control system with hydraulic pressure of sluice is improved, a kind of control scheme based on VC++ and PLC is given. Control system from aspects of hardware and software is designed, which can respectively improve systematic dependability and security and realize the automatic control of floodgate. During rebuilding Fengman hydroelectric power station of Jilin province, the control scheme has been applied and the result is good.
