基于VxWorks的某装备自动测试系统设计与实现

针对某装备的实时性测试需求、测试系统通用性和可扩展的需求,设计并研制了一套基于VxWorks操作系统的自动测试系统。该自动测试系统以工控机作为人机交互操作的核心；PXI机箱内置PXI仪器板卡和零槽控制器用于实现测试过程中激励信号的施加和被测对象响应信号的测量；系统软件采用虚拟仪器技术进行开发,虚拟仪器软件可进行二次开发和参数配置,使系统具有通用性和可扩展性。系统采用通用标准化信号接口连接器,保证了系统的扩展能力。

The Design and Implementation of Automatic Test System based on VxWorks

A automatic test system based on the VxWorks operating system to meet the requirements for the real-time testing, universality and extensibility of the test system . The automatic test system is developed with industrial computer as the core of human-computer interaction operation. In the automatic test system, PXI chassis with PXI instrument board and zero slot controller is used to implement the testing process of signal exerting excitation and the measurement of the response signal. The system software that developed with virtual instrument technology is support for secondary development and parameters configuration. Standardized signal interface connector is used to guarantee the extensibility of the automatic test system.
