Design of PC/104 Expansion Board Based on CAN Bus Redundancy
This paper designs an expansion board which is used for communication for control system of remotely operated underwater vehicle (ROV). The goal is to improve stability and reliability of the system under complex conditions. A novel method is introduced for the implementation of communication of the system based on double controller area network (CAN) bus redundancy technology. The proposed approach adopts ARM as micro-controller,PC/104 bus as the media of data transmission and reception with motherboard. A complex programmable logic device (CPLD) is used to realize the dual CAN bus redundancy strategy and logic transformation between PC/104 bus,CAN controller and ARM local bus. The experimental results demonstrate the effectiveness of redundancy technique and stability of communication system.
