This paper describes the network structure of factory. According to the actual production,the overall planning of the network core layer,convergence layer and access layer and wireless communication network,according to the realization of the rational allocation of the IP address of the network function of subnetting,to ensure real-time communication across the network and improve the robustness of the network data transmission,using PROFINET industrial network characteristics,design MRP redundant ring,reduce maintenance time,and the application of encryption transmission of wireless AP and wireless terminal,realize seamless uplink transmission control data and monitoring data,in order to avoid physical production line interference problems,the effective isolation network management and application of network based on VLAN,to solve the interference problem between network information at the same time,improve the reliability of the network.
