Gprs-based Remote Wireless Data Acquisition System Design

Remote data acquisition technologies,is a inevitable result with the development of computer network technology,communication and information technology. In the early time, the remote data acquisition is non-online,non-real-time mode. Nowdays,the remote acquisition technology is real-time,online method. And with the the development of modern computer technology,Intemet technology and communications technology,the collectors can obtain the real-time data from the remote site,relying on the variety of sensor devices installed on the site,so can do some monitoring and analysis about the situation of the site through the real-time data.GPRS (General Packet Radio Service) is a new data processing technology,based on mobile GSM network.It provides a highly efficient,new data transmission mode for the wireless data acquisition system. It can provide long-distance,high speed, large capacity, high real-time data transmission services,greatly improving the reliability and accuracy of the data.This paper has presented a wireless Remote Data acquisition system based on GPRS.In this system GPRS network is a medium for transmitting the remote data.Firstly,it presents detailed explanation of GPRS network's system structure and communication principle. Secondly,it introduces the design of hardware and software in the embedded system.The project uses ARM9 embedded processor and GPRS as the hardware platform.The Linux Operation System runs on the hardware platform.On this basis, develop application software for data communications,realizing the functions of remote data acquisition and transmission.Currently this technology is widely used in the field of wireless data acquisition,remote data monitoring and other areas.We believe that with the development of mobile communication technology and 3G technology implementation,the reliability and accuracy of mobile communications will be greatly improved.The design of data acquisition system based on ARM9 and GPRS will certainly have a broader space for development.
