基于GPS定位信息系统的设计与实现
摘要
随着无线导航定位技术、网络技术、计算机通信技术、自动化和人工智能
系统的飞速发展,使得GPS在很多领域都因其独特的优点而得到广泛应用,如广泛应用在土建测量、车辆查询与监控、工程测量、航空摄影测量、地壳运动监测、个人旅游及野外探险、紧急救助、飞机、轮船、车辆的导航与定位等各个领域,定位服务市场得到空前发展,目前市场上也存在一些定位系统绕开了无GPS卫星定位系统信号的问题,使用蓝牙、射频识别、ZigBee、WIFI等技术,这些技术虽然可以提供较高精度的定位,但其不足之处在于只能应用在特定的设备上和特定的环境中,不仅安装复杂、费用高,而且应用范围狭隘。如何扩大定位系统服务的应用范围,降低定位系统的部署成本,提高设备的利用率,使得定位系统应对突发事件的救援能力得以增强,在现实中具有非常重要的意义。 本设计是基于嵌入式系统和GPS模块等部件设计的一款定位信息系统,将接收到的数据进行读取和处理并将接收到的定位信息显示在液晶显示屏上,通过WIFI实现对定位信息数据的传输,其中WIFI选用ESP8266芯片,在硬件设计中,起通信桥梁的作用,通过HTML实现web网页在PC机端的定位信息的管理。

上海第二工业大学本科毕业设计(论文) ABSTRACT
Design and Implementation of Location
Information System Based on GPS
ABSTRACT
With the rapid development of wireless positioning technology, wireless network, computer, automation and intelligent system makes the GPS in many fields because of its unique advantages and is used in various fields widely, such as land and engineering surveying, photogrammetry, crustal movement monitoring, engineering deformation monitoring, and personal rescue, and vehicles, aircraft, ship navigation and so on. Positioning market has been an fast development. There are some positioning systems without the satellite positioning system signal which use Bluetooth, frequency identification, ZigBee, WIFI and other technologies. Not only can these technologies provide high precision positioning but its shortcomings used in specific equipment and specific environment. What’s more, complicated installation, high cost, and narrow range make its applications are limited. What is important to enlarge the application industry and the scope of the location service, to reduce the deployment cost, improve the utilization ratio of the equipment and enhance the ability of emergency, How to expand the scope of application of positioning system services, reduce the deployment cost of positioning system, improve the utilization of equipment, making the positioning system responded to emergencies can be enhanced, which has a very important significance in reality.
The design is based on embedded systems and GPS modules and other components designed a positioning system, The received data is read and processed and the received positioning information is displayed on the liquid crystal display screen, and the transmission of the positioning information data is realized by the WIFI which selects the ESP8266 chip, and design the hardware, WIFI plays a role in bridge through the web page manage the computer information. Key words: GPS; Location service; LCD; WIFI; ESP8266
