　　Abstract: In order to understand the actual situation of water management network of Xinfeng River, so that the potential network problems can be found out in time, the smart water control system network of Xinfeng River Basin is analyzed. This paper analyzes the business scale of the network based on its overall structure. The network includes four types of nodes, which are self-built River LAN, 4G wireless RTU, 4G wireless VPN and broadband wired VPN to transmit relevant data. The selection and distribution of network equipment, VLAN planning and data security are described. From the development and operation periods, based on the characteristics of the river network, this paper analyzes the selection of network equipment, the use of wireless bridges, the construction along river channels, and the management and key points of network monitoring and wiring management. The results show that in order to ensure stable operation of the smart water control system network, the design, construction, and operation stages should be considered and analyzed integrally. The results and experience of each stage can provide reference for the network application of water environment restoration projects in other river basins.
