为了满足多接口、多状态、多任务的复杂飞行器测试需求,设计复杂飞行器模拟平台,基于器上综合电子系统实现飞行器电气系统软硬件接口测试;飞行器模拟平台采用主控机和模拟器两级控制架构,主控机基于WPF框架实现人机交互,完成对模拟器的指令控制;模拟器运行在VxWorks系统下,基于WorkBench开发环境对指令进行实时解析,驱动各功能模块执行动作,实现传输速率为16384 bps、8192 bps和4096 bps的RS422接口以及最高速率为50 Mbps的LVDS接口,提供了80路OC门电路的输出,同时完成对飞行器上1553B总线的模拟;试验结果表明,该平台实现了飞行器上各系统电气接口的模拟,保证了器上综合电子系统的高测试覆盖性。

In order to meet the requirements of multi-interface,multi-state and multi-task complex aircraft testing,a complex aircraft simulation platform is designed to realize the hardware and software interface test of the aircraft electrical system based on the integrated electronic system.The aircraft simulation platform adopts two-level control architecture of the main control machine and the simulator.The main control machine realizes human-computer interaction based on the WPF framework and completes the command control of the simulator.The simulator runs under the VxWorks system and executes the instructions in real time based on the WorkBench development environment.The simulator drives each function module to perform actions.The simulator ahcieves an RS422 interface with a transfer rate of 16384 bps,8192 bps,4096 bps and an LVDS interface with a maximum rate of 50 Mbps.It also provides the output of 80 OC gate circuits and completes the simulation of the 1553B bus on the aircraft.The test results show that the platform realizes the simulation of the electrical interface of each system on the aircraft,which ensures the high test coverage of the integrated electronic system on the instrument.
