Design And Research On Temperature Acquisition System Based On GPRS And The Internet Of Things

Along with the wireless communication technology,MEMS technology and the low power embedded technology unceasing development,the wireless sensor network(WSN) technology is playing more important role in scientific research,environmental monitoring and other fields of daily life’s.In recent years,a variety of low rate wireless communication network technology rapid development.Because of low power consumption,the characteristics of self-recovery ability,the Zig Bee technology has become the focus of current research,The Zig Bee technology is the communication of short distance and low rate. The GPRS network has made up the Zig Bee’s weakness of short distance as the remote communication.The combination of the two technologies can achieve complementary advantages and establish a set of networking flexibility,expansibility and safety remote wireless data acquisition system.Begin with the research analyzes the system of technology,including two kinds of key technology GPRS and Zig Bee.Analysis of the GPRS’s network structure, interface and protocols, routing management,mobility management,service definition and Qo S description, proved that it is a kind of very applicable communication technology scheme for extending remote wireless sensor network.A comprehensive study of the Zig Bee technology’s protocol architecture,topology structure and working mode every aspects,proved that it’s a kind of excellent WSN network communication technology.This article consults a lot of domestic and international documents,design and research temperature data acquisition system based on GPRS and Internet of things hardware and software parts.Adopt TI/Chipcon’s CC2530 to complete the design of embedded node with Zig Bee compliant.Adopt Siemens’ s MC55 i module to complete the remote data transmission system.Finally to verify and optimizate the whole system.
