The Embedded ARM user Program design of Vehicle Terminal

Based on the functions the vehicle terminal needs to implement, this paper designs an Vehicle Terminal based on Embedded ARM user Program. It carries out multi-task division, parses the NMEA0183 protocol containing GPS positioning information to complete the current time, longitude, latitude and speed extraction, real-timely displays the current position on the vehicle terminal LCD for the vehicle positioning, and packs the parsed location information to sent out through the GPRS network or short message, to complete the vehicle phones, vehicle alarm application development.
