喷口-加力调节器故障检测涉及的零部件来自不同的令号、附件号及机型,工艺要求各不相同,传统纸质履历方式造成加力调节器故障检测现场零件检测数据管理复杂、反馈及时性差、质量追溯困难。针对这些问题,提出基于信息化测试设备及检测技术,以网络数据库实时传递反馈检测数据的智能测试方式满足加力调节器故障检测维修中零部件内径、外径参数测量、数据管理、质量追溯的需求。通过生产者/消费者设计模式使用LabVIEW语言实现气动量仪、数显比较仪、脚踏开关与工控机间的通信,提高了测量数据读取与处理效率。为验证系统性能,在维修现场对系统样机进行了测试。结果表明:该系统操作简便,运行稳定可靠,能显著提高检测效率,有效降低现场测试数据的管理难度。

The parts involved in fault detection of nozzle-afterburner regulator come from different task Numbers,accessory Numbers and aircraft type,and the process requirements are different.The traditional paper resume causes the complexity of data management,poor timeliness of feedback and difficulty of quality tracing.According to these problems,the information test equipment and detection technolo⁃gy were proposed,and the intelligent test method of real-time feedback test data could meet the requirements of internal diameter,external diameter parameters measurement,data management and quality tracing in the fault detection and maintenance of after regulator.Commu⁃nication among gas momentum meter,digital display comparator,foot pedal switch and industrial computer was realized by using LabVIEW language in producer/consumer design mode,and the efficiency of reading and processing measurement data was improved.In order to veri⁃fy the system performance,the system prototype was tested at the maintenance site.The results show that the system is easy to operate,sta⁃ble and reliable,which can significantly improve the detection efficiency and effectively reduce the difficulty of field test data management.
