【摘要】 对多传感器智能组合导航仪的数据采集模块进行了设计,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三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。更多还原

【Abstract】 The combination of Dead Reckoning (DR) and GPS will make the localization of mobile vehicles exactly,even when the Satellite signal is lost.The module of digital gather is designed which used 51 MCU as the key part of module in this text.After introducing the form of GPS data the signal form gyroscope and signal of tempo,the block diagram and principle picture are designed.It is very im- portant to improve the method of communication to make the transmission more effective and simpler.The procedures of software is written by assembler language,and it has been debugged and passed under the development tool of KEILC51.The whole system runs normally,and it has reached the designing require- ment.更多还原
