A large production line device often includes a plurality of production devices and a plurality of PLCs (Programmable Logic controllers) for controlling the plurality of production devices. In general, the control of production line equipment requires a complex system consisting of an upper industrial personal computer, automatic transmission equipment for feeding and discharging materials, a data router for providing data to the MES system, a notebook computer for field flexible debugging, and the like. The existing production line control system comprises a wireless Network bridge module used for accessing a wireless local area Network, a Network module used for constructing a Virtual Private Network (VPN) channel by accessing the wireless local area Network, and a CPU module used for accessing a Programmable Logic Controller (PLC) of the constructed VPN channel; the network module is respectively connected with the wireless network bridge module and the CPU module. When the production line equipment needs to be maintained or the functions of the production line equipment are increased and changed, the CPU module of one PLC can be modified, but the CPU modules of a plurality of PLCs, the operation software of an upper industrial personal computer and other parts in the production line equipment need to be modified respectively in most of the time.

The VPN gateway adopts a double network card structure, an outer network card accesses the Internet by using a public network IP, a terminal A of a network I (assumed as a public network Internet) accesses a terminal B of a network II (assumed as a company internal network), and the target address of an access data packet sent by the terminal A is the internal IP address of the terminal B. And when receiving an access data packet sent by the terminal A, the VPN gateway of the first network checks the target address of the access data packet, and encapsulates the data packet.
