摘　　要：基于美国国家仪器公司的PXI总线实时控制硬件以及图形化编程软件LabVIEW设计并集成了综合离心加压试验控制系统;在硬件方面,设计了由PXI实时控制器和Host主机组成的上下位机架构的控制系统;在软件方面,了解并掌握综合离心加压试验的需求和试验流程,设计并实现了位置式PID闭环控制、网络通讯、数据保存、以及人机交互界面等功能;并对该实时控制系统进行了地面调试,调试结果分析表明,该实时控制系统具有控制精度高、可靠性好、开发周期短,稳定性好,能够完成多回路的综合离心加压实时控制任务,并为产品集成设计提供一些经验借鉴。Designed and integrated control system of centrifugal and pressure test based on PXI bus and LabVIEW of NI company. In the hardware, design the control system of upper and lower computer architecture based on the Real--Time controller of PXI bus and computer; In the software, based on the requirement of centrifugal test and test flow, realize the function of location PID control, network communication, data storage and human--machine interaction interface. And debug the control system of centrifugal and pressure test, the result indicate that the system has advantages such as high control precision, high reliability, high real--time, high development efficiency. The control system can satisfy the multi--channel control task of centrifugal and pressure test, and provide some use for reference of integration design of product.
