The Simple Design Of GPS Positioning Massage Display Based On Single-Chip Microprocessor
Abstract
GPS is the acronym for Global Positioning System,the Global Positioning System.Its purpose is on a global scale aerial targets on the ground and accurate positioning and monitoring.
The design is based on the AT89C51 microcontroller to achieve the simple GPS positioning information display system. The main control system completed accept data，show time, longitude, latitude and other conventional features.SCM and OEM board serial communication links used by the microcontroller to accept GPS information, decode it, and then through the LED display information.GPS information is displayed cycle time, longitude and latitude.
This paper describes the use of GARMIN's GPS25-LVS series of OEM (Original Equipment Manufacturer) receiving board and SCM implementation the time,latitude and longitude of real-time, and other comprehensive information shows that the design method.Through studying on GPS OEM board and LED display module,the collection and display system of GPS’s information are designed.By using single chip computer 89C51,the GPS OEM board is controlled,thus the collection and transmission of the orientation data are realized.The orientation data are delivered to LED model for display. The practice proves that the time displayed by the system is very accurate,and the precision of orientation is high.The system satisfies the usage of the general application and certainly offers p ractical value.
