An embedded gateway of CAN/Ethernet is designed and used in remote video monitoring. The camera captures video signal which is compressed and exchanged via the CAN/Ethernet embedded gateway to the Ethernet. Its hardware system consists of the LPC2294ARM MCU which includes four controllers of CAN bus, the RTL8019AS NIC and the transceiver of CAN field bus. The software system includes three parts:protocol transition module, CAN protocol module and Ethernet protocol module. In order to improve the stabilization and dependability of the system, the embedded RTOS μC/OS-Ⅱ is adopted.
