Water gate drainage automatic control system and method

The invention discloses a water gate drainage automatic control system and a method, thereby achieving the objective to carry out remote regulation on upstream and downstream water levels. The automatic control system comprises an on-site acquiring control unit, a control center operation unit and a water gate unit management unit. The on-site acquiring control unit is responsible for storage and logic calculation of control procedures, transmission and execution of control instructions, interaction of information and information acquisition of water level. The control center operation unit is responsible for configuration of information acquired by the on-site acquiring control unit, and the remote control and network communication monitoring on devices. The water gate management unit is responsible for managing the control center operation unit, reporting project information to superior departments, and receiving the superior dispatching commands. According to the invention, labor intensity of workers can be reduced; working efficiency is increased; automatic adjustment and control for gate height can be timely carried out according to change of water levels; and drainage flows can be precisely controlled.
