Application of ZigBee Wireless Sensor Network in Harmful Gas Monitor in Oil Drilling Field

This paper proposed a kind of hierarchy wireless sensor network in the oil drilling field. This WSN is based on ZigBee protocol. In this paper, the topology control mechanism and the routing mechanism for the WSN were designed in the light of the requirement of harmful gas mo-nitor in the drilling field. In addition to this, two working modes were designed for the network. Periodic Mode and Interrupt Mode. Experimental results show that based on the topology control mechanism and the routing mechanism designed, the data could be periodically acquired with sta-bility and reliability under the Periodic Mode and the over limited data could be transmitted timely under the Interrupt Mode. The application of this WSN could effectively compensate for the deft-ciencies of the existing wired monitor system in the oil drilling field; it is of great significance to implement this network to guarantee production safety.
