Industrial Ethernet transmission method and apparatus based on 3G/4G wireless technology

The invention relates to a networked industrial control system, in particular relates to an industrial Ethernet transmission method and apparatus based on the 3G/4G wireless technology. The network structure adopts a monitoring center as the core, each monitoring point of a three-layer star-like structure of the node, the connecting mode of the monitoring station and the monitoring center adopts station-to-station VPN connecting technology based on L2TP dialing to perform data transmission, each monitoring station uses a static IP as a station network sensor, and the monitoring center can directly access the network sensor of any monitoring station via a local area network static IP. The industrial Ethernet transmission method and apparatus based on the 3G/4G wireless technology provided by the invention are based on the wireless network design of the operator, the all-weather operation demand in the field is met by the industrial network device, so that the enterprise cost is reduced,and the design structure
