基于PXI的分布式LIA测控系统结构设计

Design of PXI for a distributed control system based on LIA

摘要:

介绍了直线感应加速器(LIA)测控系统的要求、硬件结构、软件设计以及PXI总线的特点，重点阐述了利用PXI设计控制系统的方法。PXI模块的推出，为简化测控系统的部分结构提供了可能。结合“嵌入式系统”，可简化系统的结构，提高系统性能，运用CVI编程控制与集成相关的设备。通过在项目中的应用测试，证明LIA测控系统可以有效工作。

Abstract:

The design requirements of the control system for a Linear Induction Accelerator(LIA) are presented, as well as the hardware and software configuration of this system. The feature of PXI bus and the design of a DAQ/Control based on PXI are described on emphasis. Combining PXI with embedded system, the structure of LIA control system can be simplified and the performance can be improved. Relative equipments can be controlled and integrated by CVI programming. The final product has been successfully tested in the Linear Induction Accelerator.
