随着航空电子系统的飞速发展,系统对通用处理模块的功能性要求不断增加,通用处理模块的硬件功能集成化程度不断提高。文章采用硬件功能分区的方法实现了某航空显示控制系统通用处理模块的高度集成化、通用化、模块化设计,通过FPGA和应用软件的可配置实现系统要求的各种功能,可实现模块级故障的检测与隔离。经系统仿真测试和系统实物飞行试验测试验证,通用处理模块性能满足系统指标要求,并且系统的体积、重量、功耗明显减小,可靠性得到了提高。
With the rapid development of avionics systems, the functional requirements of the system for general processing modules are constantly increasing, and the integration of hardware functions of the general processing modules is continuously increasing. The article adopts the method of hardware function partitioning to realize the highly integration, generalization and modularization design of general processing module of an aviation display control system. Through the configurable implementation of various functions required by the system of FPGA and application software, the module level fault can be realized Detection and isolation. The system simulation test and system flight test prove that the performance of the general processing module meets the system requirements, and the volume, weight and power consumption of the system are obviously reduced and the reliability is improved.
