Communication system design of control areanet bus with Ethernet

According to the applications in connection with control and information networks and equipment remote control, a CAN-Ethernet connection scheme based on the communication microcontroller is put forward. A microcontroller is adopted as the gateway of heterogeneous network connection. It drives the Ethernet and CAN data link layer protocol chips directly, at the same time interprets TCP/IP and CAN application protocols, so with this scheme a high-efficiency, credible and cheap gateway can be obtained without a great deal of resources. By system expansion, an integral Ethernet-CAN connection control system can be formed and equipment remote control and resource centralized management can be realized. The design idea for implementation is described in detail, and the reliability and validity of the scheme are proved by experiments.
