Pda / Gps-based Mobile Data Collection System And Application

Along with the development of the mobile computing technique and wireless communications, the mobile device is applied more and more widely. The purpose of this paper is according to the characteristics of production date collection of industry to develop a new solution of data collection based on PDA and GPS single receiver by making use of PDA (Personal Digital Assistant), existing communication network and positioning technique with satellite.This thesis study mainly involves the embedded application, mobile communication, wireless network, and GPS position technique, local database management of PDA and data access to remote database. At first, the thesis analyzes the popular solution of data collection based on mobile device, puts forward a new solution. Then technique background is introduced such as embedded system, mobile computing, wireless communication, and GPS. Taking the gas field data collection application as an instance, we study the data collection solution system based on the PDA/GPS, such as system analysis, system design, the encoding implementation of the main subsystems etc. Finally, we make conclusion and prospect the whole system.
