【Abstract】 In view of the inertial navigation training simulator, the demand of hardware and software of the navigation simulator is given. The control and communication of the simulator are implemented by using the self-making PCI I/O card. The 8279 as a control centre manages the keyboard input and multi-bit LED (light-emitting diode) display. And the switch data is sampled and inputted by way of hardware encode circuit. The software is designed by object oriented method. The complex program flow chart is dealt with by using state diagram. To simplify the calculation of navigation parameters and optimize the Boolean-calculation and the time-sequence-control the interface-oriented mathematical models are constructed.更多还原
