摘要
针对旧式机械式分罗经噪声大、反应慢等缺点,设计了数字式分罗经.介绍了数字式分罗经的软硬件设计、性能分析及实现.该分罗经基于以数字信号处理器(DSP)为核心的硬件电路,通过CAN总线实现对陀螺罗经输出的船舶航向信息的传输.数字式分罗经以数字形式及模拟罗盘形式在液晶显示器上实时显示船舶航向信息.经过设计验证,数字式分罗经性能突出,工作稳定.
The digital compass repeater was designed to deal with the shortcomings of loud noise and slow reaction of the old mechanical compass repeater. The design of the hardware and software, the analysis of specifications and the realization of a digital compass repeater were presented in this paper. The repeater uses a DSP-based hardware circuit to realize the data transfer between gyro-compass and its repeaters. The ship＇s course is displayed on a liquid crystal screen in real time. The digital compass repeater works steadily and reliably in experiments.
