Abstract: Danjiangkou ship lift running,mode is complex Base on running classification control procedure design,will make the design more complex, operating condition variation will result in a large program modification, it is difficult to debug and function modify control process. The ship lift operation conditions in accordance with the operation preparation and operation of two phases, preparation before operation including ectuipment preparation and operation of various operating conditions of identification, operation according to the command of the transmission system control, thus completing the operation process more clearly.

Key words: Ship lift, Control system, Design, Optimization
