基于CompactPCI的抗恶劣环境CAN总线模块设计

为了扩展抗恶劣环境计算机的CAN总线接口,提出了一种基于CompactPCI的抗恶劣环境CAN总线模块的设计方法。该方法中包括基于CompactPCI的抗恶劣环境CAN总线模块的设计思路和实现过程。在该方法采用了FPGA实现寄存器设计与逻辑控制,在工控3U板幅上实现了4路光电隔离CAN总线接口的紧凑设计。该方法应经投入应用,在应用过程中取得了良好的效果。

Design of Anti-harsh Environment CAN Bus Module Based On CompactPCI

In order to extend the CAN bus interface of anti-harsh environment computer,a design method of anti-harsh environment CAN bus module is proposed.The method includes design ideas and processes of implementation of the anti-harsh environment CAN bus module based on CompactPCI.Registers and logic control is completed by a FPGA in this method.Four ways opto-isolated CAN bus interface are implemented on the industrial control 3U board.
