摘要:直升机发射控制电路用于管理和控制飞机所携带的各种武器,其通过1553B总线给导弹装订发射诸元并下达投放允许命令;总线信号实时性强、交联关系复杂,给飞机的测试带来较大难度,因此有必要对发控电路的总线系统进行研究,以完善发控电路测试方法;基于多线程、中断服务和DMA方式,提出了总线监视数据与信号波形比对相结合,通过对GJB1188A的分析,在接口控制文件未知的情况下反求信号的意义,为直升机发控电路的检查奠定基础。

Abstract:The helicopter launch control circuit is used to manage and control the various weapons that the plane carried. It is used to transmit the launch data and the command of throwing permitting by 1553B bus. The real-time character of bus signal is strong, and the cross linking relation is complicated, which brings a great degree of difficulty to the aero test. Therefore it is necessary to study the bus system of the launch control circuit to make the circuit test method perfect. The combination and comparison of the bus monitor data with the signal waveform were put forward based on the technology of multithread, interrupt and DMA to establish the foundation for the test of the helicopter launch control circuit through the analysis of GJB1188A and the data’s meaning in the condition of unknowing interface control document.
Key words: launch control circuit; 1553B bus; data reserve; signal contrast
现代飞机航空电子系统功能极其复杂,航空总线技术以其结构简单、传输速度快、误码率低的特点成为连接机载设备的关键技术,是数据交换的纽带。航空总线关系到机载设备间正常通讯的进行,并且在飞机的导航、操纵、控制、作战和信息处理等任务中其辅助作用。在对航空总线系统进行测试时,需要了解接口控制文件(ICD)对信号的定义[1],但是接口控制文件密级很高,生产厂商有时需要保密,这极大制约了航空总线设备的监测与诊断。……
