飞轮通用测试软件平台的设计与实现

在激光引信自动化测试系统中,测试参数繁多,测试过程复杂,基于LabVIEW传统设计模式的测试软件在功能扩展、后期维护方面显现出明显不足。本文提出LabVIEW扩展型生产者/消费者设计模式,以测试仪器为基础,将复杂测试过程分解成多个单一测试步骤,采用面向对象技术降低测试步骤间的耦合度,利用队列状态机控制多仪器协同工作与多线程并行执行,实现测试步骤的有效组合,最终完成复杂的测试过程。通过在激光引信自动化测试系统中的运用表明,基于LabVIEW扩展型生产者/消费者模式的测试软件可扩展性强、维护方便,具有较高的实际运用价值。该设计模式可推广至其他复杂测控软件的设计中。

Design and Realization of Universal Testing Software Platform for Flywheel[JZ)][HS)]

According to the fact that original testing equipments for flywheel are low reusability, high maintenance and unable to realize synchronous automatic test, the universal testing system for series kind of flywheel is designed. By analyzing the similarities of function and differences of interface between multiple products in the testing process, the testing software takes advantage of hierarchical structure, abstract factory design pattern and configuration files to improve the adaptability and versatility which accommodate different types of flywheel. Based on test flow table, the auto test scheme is raised to adapt multiple requests for testing. With multi-threaded parallel processing architecture, the resource conflict is solved and consummate parallel test of multiple flywheels. At present, the universal testing software has been widely used in the flywheel production with stable performance and high flexibility. The usage of testing equipment has increased by three times and the test efficiency of flywheel has been greatly improved.
