摘　　要：介绍了一种以AT89C55为控制核心,基于超声波测距原理,组合GPS定位的航道测绘仪设计方案。重点介绍了单片机与外围硬件电路的接口设计和软件编程设计,给出了GPS数据从地理坐标到直角坐标系的转换算法。系统具有自动采集水深数据、存储、回溯校核、以绘图方式显示和打印等功能,已成功应用于航道测绘中。By the use of ultrasound ranging principles to AT89C55 for central control module, combinedwith GPS positioning module, channel depth mapping system is introduced. Emphasis is put on the designation for hardware interfaces and software procedures, conversion method from geography coordinate system to rectangular coordinate system is given. An automatic measurement system for channel depth,data storage, back verification and printing, showing measurements by mapping approach to LCD, and other functions, has been successfully applied to channel depth mapping.
