【摘要】：针对惯导系统在载机静止状态下无法提供动态参数的问题,对惯导子系统进行数字仿真。在航电系统仿真中,采用1553B总线与总线控制器和其他航电、非航电设备交联,通过以太网接收外部激励数据,采用多线程技术实现主备2个惯导并发运行,设计一种惯导逻辑仿真系统。阐述系统硬件结构和软件设计,建立惯导姿态仿真模型和位置仿真模型,实现惯导各种逻辑子过程。在某型飞机航电仿真系统中的联调证明,该仿真器能够准确接收外部激励源飞行信息、故障状态,经过结算后周期性地向总线控制器输出飞机位置数据、姿态数据等动态参数,执行某型飞机航电设计文档中相关惯导逻辑,并向总线控制器反馈惯导子系统状态。
[Abstract]:Aiming at the problem that the inertial navigation system can not provide the dynamic parameters under the static state of the carrier, the simulation of the inertial navigation system is carried out. In the simulation of avionics system, 1553B bus is used to cross link with bus controller and other avionics, non-avionics equipment is crosslinked, external excitation data is received by Ethernet, and two inertial navigation systems are operated concurrently by multithreading technology. An inertial navigation logic simulation system is designed. The hardware structure and software design of the system are described. The simulation model of inertial navigation attitude and the simulation model of position are established to realize various logic sub-processes of inertial navigation. The combined adjustment in a certain aircraft avionics simulation system proves that the simulator can accurately receive flight information from external excitation sources, fault state, and periodically output aircraft position data, attitude data and other dynamic parameters to the bus controller after settlement. The related inertial navigation logic is executed in the avionics design document of a certain aircraft, and the status of the inertial navigation subsystem is feedback to the bus controller.
