基于LabWindows/CVI的远程接口单元测试系统软件设计

针对航空机电系统中远程接口单元(RIU)信号种类多、总线接口控制文档数量大、功能复杂的特点,测试软件采用模块化设计思想,基于LabWindows/CVI平台开发,将硬线配置、总线管理、测试流程、用户管理等信息都存储于数据库中,降低应用软件的复杂度、提高软件的灵活性、可维护性。测试软件提供了自动测试功能,操作简洁,减轻工作人员测试工作量;自动测试流程可在数据库中编辑,通用性好,灵活性高。实验应用表明,该软件功能满足测试需求,性能稳定,已成功应用于远程接口单元的现场测试中。

Design of Remote Interface Unit Testing System Software Based On LabWindows/CVI

The remote interface unit in the aviation electromechanical system is characterized by multiple types of signals, large number of icds and complex functions. For this the test software adopts modular design idea, based on LabWindows/CVI platform development, to store the hard line, bus management, test procedures and user management in a database, reduce the complexity of the application software, improve the software"s flexibility and maintainability. The automatic test process can be edited in the database, with good generality and high flexibility. The application proves this program meets the testing needs and has excellent performances in stability. It has been successfully applied to the field test of remote interface unit.
