Title Design of Wireless Data Acquisition System Based on GPRS 

Abstract：As the rapid development of communication and computer technology, especially the persification and improvement of wireless transmission means, wireless data acquisition technology has been more and more widely used. In order to realize data communication, this wireless data acquisition system is on the base of GPRS technology which features with fast login, billing by flow and always-on-line, etc. It has incomparable advantages towards sudden data transmission. Taking advantage of base station of mobile operator and using characteristics like high network coverage rate and good transmission performance, GPRS can provide a stable and reliable transmission means for current data acquisition system, which represents a new choice for wireless data transmission.

Based on the design of refrigeratory control system, the thesis is aimed at completing the design of hardware and software on the base of GPRS data transmission system. Using MSP430F5438A Single Chip Microcomputer, the author adopts modular design and studies SCM from sensor module, A/D transmission module, GPRS wireless communication module and data display and acquisition module respectively. Focused on the design of GPRS drivers, the author takes SIM800C as the system GPRS module and complete data transmission by SCM. Through testing, this system is verified reliable, and can receive the corresponding real time data by remote wireless control, which reaches the design requirements.
