摘　　要：为解决传统光纤陀螺罗经系统价格昂贵的问题,利用低成本的光纤陀螺罗经和双天线卫星定位定向系统组成组合罗经的主罗经单元成为重要措施。组合罗经显控单元的主控芯片采用基于Cortex-M3的LPC1768,为了减少大量代码的编写、缩短软件开发周期,屏幕选用迪文串口屏,通过串口接收主罗经发来的报文,将船舶航向以罗盘图片的方式在屏幕上实时显示出来。同时,为了方便不同的用户使用,设计了3种显示模式:罗经模式、航向模式以及导航模式。经实船测试,该显控软件的设计可行且能够满足航行要求。In order to solve the high cost of the traditional fiber optic gyro compass system,the main compass unit of the integrated compass is composed of the low cost fiber optic gyro compass and the dual antenna satellite positioning and orientation system.The main control chip of the integrated compass display and control unit adopts the LPC1768 based on Cortex-M3.In order to reduce the writing of a large number of codes and shorten the software development cycle,the screen uses the DWIN serial screen to receive the message from the main compass through the serial port,and the ship's heading is displayed on the screen in the form of a compass picture in real time.At the same time,in order to facilitate different users,three display modes are designed:compass mode,heading mode and navigation mode.The real ship test shows that the design of the display control software is feasible and can meet the navigation requirements.
