摘要
本文对多传感器智能组合导航仪的数据采集模块进行了设计,并利用51单片机作为核心部件构架整个模块。给出了系统框图、原理图设计。介绍了GPS数据格式以及陀螺仪信号形式、速度传感器信号特点,利用数据通信原理的知识将3个数据信号有机地融合,从而创造性地定义了传输数据的格式,并采用了特别设计的传送方式。采用51汇编语言进行了软件的程序编制,并在单片机仿真环境下调试通过,已在硬件环境下试运行。整个系统运行正常,达到设计要求。
A data sampling system combined Dead Reckoning （DR） and GPS technology is presented in this paper. The frame module is designed with 51 MCU as the key part of in the overall system. Through analyzing the GPS data form, the gyroscope signal form and signal feature of tempo sensor, we integrate these three signals and define a innovated data transferring format. The procedures of software is written by assembler language, and it has been debugged and passed under the development tool of KEILCS1. The whole system runs normally, and it has reached the designing requirement.
