The wireless monitoring and warning system in the wide-area dangerous environment based on ZigBee

For the petrochemical industry wide area dangerous environment, and puts forward the ZigBee production technology in the monitoring and warning system, with its features and advantages, the application project and hardware design scheme in petrochemical industry are introduced in detail. The system is proposed based on the structure of two layer clumps of wireless sensor network topology structure, overcomes the limitations of the cable sensor network, and avoids the high energy cost of the other wireless technology. Network capacity is large, networking ability is flexible, the node is low cost.
