摘要
介绍一种指示船舶航向信息的模拟装置——新型航海模拟罗经,阐述了模拟罗经的组成及工作原理,提出利用复杂可编程逻辑器件(CPLD)电路来控制步进电机转动,步进电机转动带动仪表盘和绝对式旋转编码器转动,编码器可实时检测出模拟航海罗经位置和方向,并反馈给单片机控制系统。控制单片机根据视景系统的航向信息和编码器读出航向进行比较处理,从而使模拟罗经航向指示与视景航向一致。经过实验证明,该模拟罗经具有结构简单、工作可靠、仿真效果好、推广价值高等优点。
The simulative course device of watercraft, a new simulative compass is discribled. The composition and operating principle of simulative compass are analysed. The step power-driven machine is turned and the angle and direction of simulative compass is tested by absolute encoders. A accurately control menthod based on CPLD driving the simulative compass is introduced. The scene course and angle of new simulative compass are managed by singlechip system. This simulative compass has advantages such as simple structure, reliable operating, good simulation.
