Development of RTX-based flight gyroscope

摘要:

针对飞行陀螺性能测试系统高实时性的要求,设计实现了基于PCI总线架构和RS422总线的测试系统硬件,并提出了基于RTX的测试软件开发解决方案。通过Windows+RTX平台,使系统拥有了较好的实时性,同时也保留了windows操作系统在测控软件开发方面的优势。系统采用了模块化、层次化设计,分为和底层对接的驱动层,负责业务的逻辑层和与用户交互的用户层；每个层次根据实际要求进行模块化的封装。通过开发基于底层FPGA的相应驱动层,封装逻辑层上各个板卡接口函数,构建基于用户需求的稳定可靠的上层界面程序,实现了对飞行陀螺性能的精准测试。经实验验证,测控系统满足测试需求,为未来测试设备研发提供了新思路与参考。

Abstract:

In order to meet the requirements of high real-time performance of the flight gyroscope performance test system, the test system hardware based on PCI bus architecture and RS422 bus was designed and implemented, and the test software development solution based on RTX was proposed. Through the Windows+RTX platform, the system has good real-time performance, and at the same time, it also retains the advantages of the Windows operating system in the development of measurement and control software. The system adopts a modular and hierarchical design, which is divided into a driving layer that connects with the bottom layer, a logical layer responsible for the business and a user layer that interacts with users. Each level is encapsulated modularly according to the actual requirements. By developing the corresponding driver layer based on the underlying FPGA, encapsulating the interface functions of each board on the logic layer, and constructing a stable and reliable upper-layer interface program based on user needs, the accurate test of the performance of the flight gyroscope is realized. After experimental verification, the measurement and control system meets the test needs and provides new ideas and references for the research and development of test equipment in the future.
