中文题目多功能 GPS 液晶显示定位系统设计摘要全球定位系统（GPS）是一个卫星系统，由分布在 6 个轨道平面上的 24 颗卫星组成。它具备全球覆盖、全天候、测量精度高、观测时间短等特点，它在任何时候，地球上任意地点都能够同时搜索到其中的 4 颗卫星。卫星可以收集诸如位置点的纬度和经度之类的数据，从而实现诸如定位，导航和定时之类的功能。GPS 技术目前已经广泛应用于军事、交通、测绘等领域，主要是用于运动导航、轨迹记录、大地测量等，为人类社会的发展做出了巨大的贡献。所以对 GPS 技术的研究具有非常重大的意义。本论文主要研究 80C51 单片机、GPS 模块、液晶显示屏、温湿度传感器、大气压传感器、语音播报模块等组成的多功能 GPS 液晶显示定位系统，此系统可以通过液晶显示屏对采集到的经度、纬度、时间、海拔、温度、湿度、大气压等信息进行显示，并实现日期和时间的语音播报，是一个很具有使用价值的系统。关键词：GPS，单片机，液晶显示屏，传感器，语音播报IAbstractGlobal positioning system (GPS) ,is a System made up of 24 satellites satellite, distributed in 6 orbital plane, has global coverage, all-weather, high measurement accuracy and short observation time and so on. It can search for four satellites of them at any moment and place at the same time. Data information such as longitude and latitude can be collected by satellite, so can achieve positioning, navigation, timing and other functions. GPS technology has been widely used in military, transportation, surveying and mapping fields, mainly for motion navigation, trajectory recording, geodesy and so on. It has made a great contribution to the development and progress of human society. Therefore, the research of GPS technology is of great significance.This paper mainly studies 80C51 microcontrollers, GPS module, liquid crystal display, temperature and humidity sensor, atmospheric pressure sensor, voice announcements sensor constituent multifunctional GPS LCD positioning system. The system can display l...
