飞机失速时会旋转下坠,为了研究该状态下的空气动力学问题,设计并实现一套应用于风洞旋转模型的测试系统;该系统硬件采用基于PXI总线的数据采集模块,软件设计分为运行管理、数据采集和数据处理3个子系统。在各子系统之间通过DataSocket通信技术实现指令及数据的传输,由用户以中心调度的方式指挥各子系统完成相应功能;该测试系统在已成功应用于试验,并取得了良好的效果,这种设计逻辑结构清晰,自动化程度高,并具备了较强的通用性。
In order to study the aerodynamics problem in this state, a set of test system for wind tunnel rotation model is designed and implemented. The hardware of the system uses the data acquisition module based on PXI bus. The software design is divided into operation Management, data acquisition and data processing 3 subsystems. DataSocket communication technology between the subsystems to achieve the instruction and data transmission, by the user to the center of the scheduling system to direct the various subsystems to complete the appropriate function; the test system has been successfully applied to the test, and achieved good results, which The design logic structure is clear, high degree of automation, and has a strong versatility.
