设计了一套基于PXI平台的软件框架结构，能够应用于数字化核仪器系统设计。该框架被设计成一种层次化的结构，各层之间相对独立，并通过标准数据接口进行数据交互。仪器硬件模块及数字化处理功能模块被设计成框架中的模块库，并呈现为LabView中的调用库，极大地方便了系统的定制设计，并增强了可重用性。为了保证框架结构下的系统数据传输性能，设备驱动程序经过优化，并能支持异构硬件设备的协同工作。测试结果表明，基于该框架实现的系统在满足可重用性、可靠性和可用性的条件下，仍能获得优良的数据传输性能。

In the paper , a new software framework structure based on PXI platform is designed , which can be applied to digital nuclear instrumentation systems .The framework has a hierarchical structure .Each layer is relatively independent of the others , and the data is transferred via optimized interfaces .The hardware modules and software digital processing modules are designed as module libraries in the framework , which could be easi-ly implemented in LabView .The device driver has been optimized in order to guarantee the performance of data transmission and the ability of heterogeneous hardware running together .Results of the test show that systems based on this framework can obtain good data transferring performance , and have advantages of reusability , reli-ability and availability .
