Gps Data Collector Based On Embeded System

GPS data collector is the basic technology of developing GPS receiver and bears the responsibility for receiving and storing the GPS data which is output by GPS-OEM board. The meaning of this design is that develop a GPS data collector base on embedded system for the requirement of GPS data collector in science experiment (such as field work, variable type of GPS-OEM board, rapid multi-user shared data, easy to extend the function).This paper begins with the GPS data collector in science as its starting point and considers from the portability, universality, data sharing, and function extension. Give the design thoughts and design plan of data collector through analyzing the requirement of GPS data collector equipment. This paper's task is:First, arrive at the basic plan that embedded system as the core through analyzing the requirement of data collector in science experiment.Second, propose the detailed plan on the base of the basic plan and elaborates the realization processes of hardware and software of the equipment. In the detailed plan, the hardware core is ARM Micro-controller unit and SD memory cards and the software core is UC/OS-Ⅱreal time operating system and file system.Finally, test the data collector and its application and analysis the result of test.Through the above study and practice achievement, provide a GPS data collector plan which based on ARM and SD cards. Test results of the equipment show that in the science experiment, this design has the advantage of portability, universality, data sharing and easily extending function. It reaches expected effect.
