    摘要:

    针对飞控计算机在出厂前因无整体测试环境而无法进行全时序测试的问题,设计了基于DSP+FPGA的飞控计算机硬件及全时序综合测试装置。根据功能需求设计装置的总体架构,以DSP+FPGA为核心模块实现多种信号处理,通过构建ARINC429、LVDS和RS-422通信链路完成数据通讯,实现对传感器、执行机构、安保机构、数据链等飞行器组件的模拟,构建出整体测试环境,在飞控计算机配合下完成硬件及全时序测试。测试结果表明该装置功能、性能及实时性满足飞控计算机全时序测试要求,实现了对飞控计算机真实工作环境的模拟。

    Abstract:

    Aiming at the problem that the flight control computer (FCC) can not carry out the sequence test because there is no the overall test environment of the flight control system in the factory, the hardware and sequence integrated test device of FCC based on DSP+FPGA is designed. According to the functional requirements, the overall structure of the device is designed. The DSP and FPGA is used as the core module to achieve a variety of signal processing. In order to simulate the components of the aircraft such as sensors, actuators, security mechanism and data-link and build the overall test environment, the communication links of ARINC429, LVDS and RS-422 are built to complete the data transmission. Finally, the hardware and sequence test is completed in coordination with FCC. The test results show that the function, performance and real-time of the device meet the requirements of the sequence test, and realize the simulation of the real working condition of the FCC.
