CHEN Shao-feng, DENG Zhou-hu, XIE Bing, et al. Remote transmission system of WSNs data in area without network[J]. 2014, 33(6): 93-96. DOI: 10.13873/j.1000-97872014.06.019.
To solve problem of wireless sensor networks( WSNs) monitoring in areas without network coverage
design and realize a WSNs data remote transmission system. The system consists of data differential transfer unit deployed in area without network coverage and switching unit deployed in area covered by network
ARM controller is used as core and respectively integrates 2. 4 GHz band data transmission module
UHF / VHF band data transmission module and public network access module. To enhance its wild life cycle
use wind and solar power generation system and introduce wakeup scheduling management strategy. Wild test show that the system can achieve data remote transmission reliably and efficiently.
