Design of a CAN Network with Ethernet and Wireless CAN Interface

Abstract:

Controller Area Network (CAN) is a leading serial bus or network for embedded control since this protocol’s development in the early 1980s, and Ethernet has become the dominant LAN architecture, currently which also is widely applied in embedded control. In order to resolve the interconnection of CAN network and Ethernet, a CAN network with Ethernet and wireless CAN interface is designed, which contains a wired and wireless CAN-Ethernet gateway based on μIP TCP/IP stack protocol, a wired CAN network and a wireless CAN network. Microprocessor STC12C5A60S2 is used as the MPU in the gateway, Ethernet controller ENC 28J60 is connected to Internet through adapter HR911105A and RJ45, CAN interface chips are SJA1000 and PCH82c250, wireless module utilize the single RF transceiver chip nRF2401. The structure of hardware and software of this system are presented, and testing program show that this system can transport data with each other among Ethernet, the wired CAN nodes and the wireless CAN.
