Wireless Data Acquisition System Design
Based On GPRS


Abstract: In this paper，data acquisition technology combine with GPRS long-range wireless data transmission technology，as a good system used in telemedicine to improve the flexibility of the measurement and control system. It provided a necessary technical way for family medicine and community health care. Especially for a number of cardiovascular patients，acquisition physiological signals of sudden cardiovascular disease as soon as possible，to provide a basal data for medical diagnosis.
In this paper，details of system hardware and software research and development， including the following aspects:  1，The first analysis of wireless data transmission technology and data acquisition system at home and abroad of the status quo and development trends，clarifying study the significance of the subject. Measurement and control system in accordance with modern data acquisition system for the special requirements of the major research to determine the content of this article. 2，Given hardware and software design and concrete realization of AT89C51 MCU and GPRS wireless module. 3，Using the GPRS wireless communication technology to achieve long-range data communications， has enriched the remote telemedicine systems pass letter means a very good solution to the special circumstances of remote communication problems. 4，F(xiàn)or this data acquisition system， using the server-side software， to test and debug this system.

Keywords: wireless data transmission technology，long-range wireless data transmission module，GPRS，SIM300，MCU
