Abstract
The invention discloses a modularized channelized Ethernet gateway comprising an RAM processor, an A/D converting circuit, a CAN controller and CPLD serial port management. The A/D converting circuit, the CAN controller and the CPLD serial port management are separately connected with the RAM processor. The A/D converting circuit is also connected to a data acquisition module. The CAN controller is also connected to a CAN interface. The CPLD serial port management is connected with a plurality of expansion serial ports. The modularized channelized Ethernet gateway is advantaged by providing the plurality of serial port expansion interfaces, realizing conversion from a CAN to a TCP/TP communication protocol, and realizing remote monitoring and management of devices on industrial sites. The he modularized channelized Ethernet gateway is also advantaged by high anti-interference capability.
Description
Technical field
The present invention relates to a kind of protocol converter, be specifically related to a kind of modular channelizing ethernet gateway.
Background technology
Along with the arrival of the age of Internet economy, the application of the IP network based on ICP/IP protocol is widely used, and utilizes Internet resources can realize the network insertion of equipment, and equipment networking monitoring has become the development trend of automation.Especially aspect the various fields such as Industry Control, data acquisition or industrial monitoring, all can use on-the-spot multiple devices are connected together, carry out automation networking monitoring.For example, in modern industrial production is controlled, need simultaneously Monitoring and Controlling multiple devices or gather several data simultaneously, and the serial ports number of common desktop computer, notebook computer etc. itself is limited, can not meet industrial needs.When communicating, multiple devices communicate, and its communication protocol is different, do not need its agreement to change, and can intercom mutually.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of modular channelizing ethernet gateway is provided, this protocol converter can provide a plurality of serial ports expansion interfaces, the transformation of realization from CAN to TCP/IP communications protocol, realization is to the remote monitoring of industrial field device and management, and this equipment antijamming capability is strong.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
