Realization of Interactive Communication among Multi-Sensors Based on CAN Bus
Aiming at the problems of the interactive communication among infrared multi-sensors under the electromagnetic interference, an interactive network is developed based on CAN bus controller which is embed in TMS320F2812 DSP. After the hardware design of the network system is introduced, a application layer protocol of CAN bus network for simple and effective communications is proposed. Following the protocol, software program is designed, and the transmission efficiency is improved obviously. Finally, the relationship between nodes and baud Rate is shown after analyzing the transmission time delay.
