WSN-based Long-distance Monitoring System Research And Design

The birth and development of Internet of Thing (IOT) make humans go into Intelligence age,whose core idea is connection of the physical world、the human world and information worldeach other. As one of the core technologies, the wireless sensor network (WSN) also stepsinto rapid development period.WSN fusions network communication、 informationprocessing、sensor technology and so on, is a very front research field,which highly crossmany subjects, has a very broad space for development and application prospect.Based on the ZigBee technology、CDMA technology and embedded technology as thefoundation, the construction process of the wireless sensor network remote monitoring systemis introduced detailed in this paper.Firstly, for data acquisition about the monitoring area,hardware platform is CC2430series sensor nodes,which is produced by Yidaocompany.Based on this hardware platform, the realization process of software is introduceddetailed, including transplantation of TinyOS operating system、implementation of theprotocol ZigBee and so on.For the acquisition of information transmission, an embeddedgateway based S3C2410A core processor is designed in this paper.Inside,hardware partincludes includes S3C2410A minimum system、ZigBee wireless transmission module andCDMA wireless communication module, software part includes transplantation of Linuxembedded operating system、driver development and application development.Through thegateway node node, and realize the close of transmission and remote data transmission waywith the remote data transmission, and according to the different applications, design of threedifferent remote transmission.Last, the design of background monitoring center is introduced.
