Problems solved by technology

[0002] The integration of traditional non-high-speed Ethernet equipment into high-speed Ethernet not only requires embedding a huge high-speed Ethernet communication protocol code into the software control system of the equipment, but also requires a large number of changes in the design structure of the equipment. The transformation technology is complex and costly, which is not conducive to Integration of Industrial Equipment with Fast Ethernet

Abstract

A TCP / UDP communication interface device based on a multi-channel random access memory comprises a control unit and a communication unit. The control unit is used for receiving, sending and calculating messages of a TCP / UDP high-speed Ethernet and messages of peripherals, providing indicating instructions and system information for a connection mode module in the communication unit, and providing software support for the whole device. The communication unit is connected with the control unit into a whole through a control interface circuit, is used for being in communication with a TCP / UDP network to exchange TCP / UDP data, is in communication with the peripherals, provides standard circuit interfaces for the peripherals, is used for enabling the communication interface device to be in interconnection with the peripherals, is used for indicating the current working state of the communication interface device, and is used for providing a restart function for the communication interface device. The TCP / UDP communication interface device has wide generality, and the communication interface device can be in interconnection with any peripheral to exchange TCP / UDP messages when the peripheral meets the requirements for the specification of an interface circuit in the communication interface device.

Description

technical field [0001] The invention relates to the technical field of industrial network communication, in particular to a TCP / UDP communication interface device with wide versatility. Background technique [0002] The integration of traditional non-high-speed Ethernet equipment into high-speed Ethernet not only requires embedding a huge high-speed Ethernet communication protocol code into the software control system of the equipment, but also requires a large number of changes in the design structure of the equipment. The transformation technology is complex and costly, which is not conducive to Integration of industrial equipment with high-speed Ethernet. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a TCP / UDP communication interface device based on multi-channel random access memory, so that it has wide versatility and can be interconnected with any perip...
