Abstract：In this paper, the monitoring && controlling system based on CAN Field-bus technology is discussed. The system is been designed to control Hi-Lo temperature experimental box, and the emphasis of the paper consists in transferring information by CAN Field-bus. The CAN Field-bus interface board embedded MCP2510 bus controller is been explained in detail, including its software design and hardware design. The hardware design is main about the structure and interface of MCP2510, the software is main about the programming design among MCP2510 && MCU.
