摘要
基于PSB(Packet Switching Board)技术,设计了CompactPCI高可靠性硬件平台。该系统内的任意板卡都可以通过PSB实现数据的交换,并利用主控CPU板卡对其数据包进行侦测。系统平台可以对包括主系统板的所有插件提供冗余备份,故障板可以被自动隔离,备份件可以被自动连接,可以在线插拔系统板及其它插件。由于采用热备冗余设计具备高可靠性,在现代通信、航天、军事等领域具有广阔的应用前景。
In order to get high availability（HA） industry control platform, we design a redundant system-slot CompactPCI hardware platform with 14 slots, based on PSB. Every boards of the system can communication by PSB, and its packet can be inspected by CPU board which is main control, of the system. This platform supports redundancy and hot-swap for all boards including the main CPU board. Failed board can be isolated and the stand-by one can be connected automatically, boards can be inserted and extracted without shutdown of the system. Because of redundant design, it can be widely used in modern communication, aerospace, and military applications.
