| Abstract: | As the base of constituting analytical instrument network, an intelligent node of the CAN network for the gas analytical instrument based on DSP TMS320C2812 is designed. The structural block diagram of the analytical instrument and the hardware interface circuit are designed, and in software design, partial C language program for CAN initialization is given. The problems probably encountered in designing intelligent node and their solutions are analyzed. This intelligent node has been debugged successfully. The networking of the analytical instruments is significant to directly control quality of products in process industries. |
