Design of environmental information monitoring system based on GPRS

摘要

This paper introduces a design of environmental information monitoring system based on embedded technology. The system equips an ARM7TDMI-based microprocessor and GPRS as its main controller; the system composition is described, and consists of the sensor data acquisition, remote transmission of short message service (SMS) and LCD displaying. Software processes with μC/OS-II is shown, and the method of realizing remote transmission by SMS is discussed in detail, the data collection, remote transmission and playing of environmental information are realized successfully.
