Abstract：In recent years, extreme weather frequently occurred in our country such as flood and drought. As to this problem, our government has presented that it is going to intensify investment of construction of water conservancy in 12th five-year plan. Meanwhile, with promotion of information technology in water conservancy, automatic monitoring system of sluice gate, the most important part in water conservancy, is paid more attention now.The automatic monitoring system of sluice gate including automatic control technology, computer network technology, sensor technology and communication technology not only improves accuracy, flexibility and rapidity of information gathered from sluice gate, but also enhances reliablitiy and safety of sluice gate, which could give government leaders the scientific basis in order to make correct decisions. In this paper, the research object is the automatic monitoring system of sluice gate of the town yuecheng in hebei province. First, PLC is used to control local controller unit and gathers some kind of information of sluice gate. Then the data is transferred to PC by Ethernet communication technology. PC will display and deal with all the information. What`s more, PC could also transfer decision to PLC by Ethernet communication technology. After receving instructions from PC, PLC will execute these instructions to control local controller unit. By this way, the communication between PC and PLC is achieved.
