The Design Of The Gateway Between Internet And Can-Bus Basing On Embedded System

With the swift and violent development of embedded application, the computer technology, the communication as well as the Internet widespread application, induced the industry control domain profound technology reform, the structure netting and system opening of the control system will be development tendency of the control system technological.CAN (Control Area Net) is one kind of outstanding field bus, found in a wide range of application in our country. The more and more industrial equipments are using the CAN bus, composed the distributional control system. The Internet based on TCP/IP protocol is popular besides in the general-purpose calculator (PC), starting to enter the industrial equipment domain. The equipment with Internet will greatly enhance the control system distributional characteristic. Now,we brought forword the topic about the interlinkage between CAN bus and Internet.This article has studied the protocol gateway between CAN bus and Ethernet based on μC/OS-II operating system.It realized real-time interconnection between the Ethernet and the CAN bus, permitted every authorization upper user on Internet visiting production layer and monitoring equipments in production layer.This article is precisely based on μC/OS-II+TCP/IP+CAN solution...
