Industrial Ethernet IP address conversion gateway

Abstract

The present invention discloses an industrial Ethernet IP address conversion gateway. The gateway comprises a housing, a power supply terminal is arranged at the external portion of the housing, the power supply terminal is connected with a power system through a power supply anti-surge unit arranged in the housing, the power system is connected with a LAN1 Ethernet unit, a LAN2 Ethernet unit andan ARM processor, the LAN1 Ethernet unit and the LAN2 Ethernet unit are connected with the ARM processor, the LAN1 Ethernet unit is connected with a first RJ45 interface and a second RJ45 interface, the LAN2 Ethernet unit is connected with a third RJ45 interface, the first RJ45 interface is connected with a first ESD protection unit, the second RJ45 interface is connected with a second ESD protection unit, the third RJ45 interface is connected with a third ESD protection unit, the first ESD protection unit and the second ESD protection unit are connected with a dual-5R45 bus base, and the second ESD protection unit is connected with a single-5R45 bus base. The independent LAN1 Ethernet unit and the LAN2 Ethernet unit are independently operated to achieve the mapping from an IP of a deviceconnected with the LAN1 to a LAN2 port through forwarding of an assigned transmission layer, and therefore, the industrial Ethernet IP address conversion gateway is safe and efficient.

Description

technical field [0001] The invention relates to an industrial Ethernet NAT conversion gateway, in particular to an industrial Ethernet IP address conversion gateway. Background technique [0002] As the country proposes the strategic goal of industrial manufacturing 2025, industrial equipment networking has become the common awareness of various manufacturers, and the best way for industrial field networking is undoubtedly industrial Ethernet. Industrial Ethernet technology has now become one of the mainstream networking technologies. Its standard is IEEE802.3; industrial Ethernet has the following advantages for industrial field control: (1) easy installation and wiring; (2) modularization; (3) easy diagnosis; (4) self-construction; (5) convenient for enterprises manage. Since networking brings so many advantages, it will inevitably bring about a new round of factory automation reform, and equipment information networking will become an effective injection to help industri...

Problems solved by technology

[0003] Industrial field equipment is often diversified, and all kinds of equipment need to be managed online. There are new equipment and old equipment. For new equipment, most of its IP addresses can be modified, but some manufacturers have IP designation requirements, and new equipment systems The IP in the IP and the specified requirements are incompatible, which brings a certain degree of trouble to the networking; and the IP address of the network port of the old equipment cannot be modified, so it is impossible to realize the unified IP address to the same network segment for management

[0004] At this stage, many people choose the method of router NAT address translation. This method is based on the forwarding of the network layer in the OSI model. The implementation method is relatively simple. Most routers are completed by configuring the NAT mapping table, and the conversion of NAT must specify the routing port , in this way, there are problems of limited address routing table, network security, single-port routing and low conversion efficiency
