A Portable Embedded Data Acquisition and Communication System

Abstract

The data acquisition equipment is very useful and popular equipment in agriculture and the other fields. This paper introduces the design of a portable data acquisition and communication system used in cropland. It collect signals of various analog and digital sensors, GPS space and time data, saving data by USB interface and transmission through WCDMA or Bluetooth. The key technology of the system is the use of embedded microprocessor ARM, Linux Operating system and WCDMA wireless communication. This paper mainly analyzed the basic principle, hardware interface and software flow chart of this system.
