摘　　要：某型号雷达的内网是基于分时传输体制的。原有的数据中断接口板是基于ISA总线标准,但是该总线标准数据传输实时性和吞吐能力有限且很难实现改造升级。为了提高雷达数据的实时响应,避免数据冲突,实现定时信号的可靠传输,利用PCI9052芯片设计了PCI的中断接口板,具有良好的即插即用和实时响应的特性。The internal network of radar with certain type is based on time-sharing transmission system.The original data interrupt interface board is based on the ISA bus standard,but transferring standard data in real time and throughput of the bus is limited and it is difficult to achieve the upgrading.In order to improve the response of radar data in real time,avoid data conflicts and achieve reliable transmission of timing signals,the chip PCI9052 is used to design PCI interrupt interface board,which has a good plug and play and real-time response characteristics.
