Abstract:
Long-term and stable wireless sensor network (WSN) node′s operation should be included in large-scale unattended industrial production. Here a kind of WSN node applied to multiple large-scale industrial productions is designed by analyzing WSN technologies and its multiple applications, and studying the node′s practical operating environment. A new method for applying image-recognition technology realized initially by using plenty of expensive sensors is proposed to analyze video data. When the node is applied in such situations as unattended operation and field monitoring, solar power generator is adopted to provide energy for the node system by charging a battery. The communication between WSN and background monitoring center is realized by GPRS module, and the operation of node is managed by transplanting μC/OS-Ⅱ into the ARM7 kernel microprocessor. The results show that the WSN node designed in this paper can be applied to control information transmission of wild and unattended large-scale industrial applications with stable and reliable performance.
