Base Station Design And Applied Research Of Self-organized Heterogeneous Wireless Sensor Network

With the developping steps of sensor technology and hardware, self-organizing wireless sensor networks (WSN) have being used more and more fields and directions, such as industry, agriculture, urban management, bio-medical, environmental monitoring, and disaster relief. Wired control system in Coal mines requires expensive wiring costs, complex maintenance, and can not change the network structure dynamically, its capacity is small, and can only be extended to the coal mine roadway, without monitoring of the mining areas.In this paper, after the research on self-organizing wireless sensor networks, we designed the base station based on embedded Linux for system to achieve data reception, processing, storage, forwarding, and display functions, as a sink node. We provided terminal GUI to observe system status in real-time. The main contents of this paper include multimedia sensor node design, RF transceiver module design and implementation, base station and terminal hardware and software design, and also low-complexity video compression algorithm. With the deployment of the system, Information of monitoring area, or Miners status, such as temperature, humidity, gas dengsity, video, can be easily observed, which ensure a way of mine safety, accident prevention, detection, and rescue work. The research provides important guidance and high practical value.
