摘　　要：交换机是通信网络的核心设备,必须具备高可靠性。主控单元是交换机的核心部件,其可靠性直接决定了交换机的可靠性。本文基于PSB技术,设计了CompactPCI高可靠性的硬件平台,以实现交换机主控单元热备冗余的高可靠性要求。该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,可以在线拔插系统板及其它插件,系统内的任意板卡都可以通过P S B实现数据的交换。由于采用热备冗余设计,具备高可靠性,在通信控制领域具有广阔的应用前景。Switch is the core communication network equipment, it must with high refiability, main control unit is the core component of switch,the reliability of main control unit directly determine the reliability of the switch. Based on the PSB technique, a CompactPCl highly reliable hardware platform has been designed in this paper in order to meet the high reliability requirements of hot standby redundancy of switch＇s main control unit.The system platform can provide redundancy to all plug-ins including the main system board, fault board can be automatically isolated,backup file can be automatically connected,we can plug system board and other plug-ins online, Any board in the system can exchange data by PSB. The hot standby redundancy design, with high reliability, has broad application prospects in the communication control.
