Applied Research For Wireless Networking Technology Of Oilfield Monitoring System Based On ZigBee Protocol

In China, the oilfields are mostly away from the city, and in the harsh outdoorenvironments. Transport and exchange of information are extremely inconvenient, and the oilwells’ locations are much dispersed. Therefore, remotely automated monitoring andmanagement is of great practical significance for the oilfields.ZigBee is a new kind of short distance, low rate, low cost, and low power wirelessnetwork technology. It has a strong self-organizing capacity and high security, so it is verysuitable for wireless sensor networks Oilfield monitoring system based on ZigBee protocol isdesigned, and wireless networking functiona is achieved in this paper. As a control andprocessing core, low power MSP430F149microcontroller is used to sample and analyzewellhead’s temperature and pressure information, etc, through the sensors. Sampling resultsare analog-digital transformed and sent to the wireless RF module XBee Series2, and thentransmitted to superior equipment or gateway via ZigBee network. At last collected data willbe sent to the remote monitoring center through GPRS/CDMA module. Enable staff to graspthe working conditions of the pumping wells timely and accurately. Thus the production anddispatch instructions can be feedback to the first line. ZigBee network in this system uses thead hoc network program, whose advantage is easy to implement and flexible networking,low-cost and short development cycle. Because this system works in the field in the situationof long-term stability, and almost all the node devices are lithium battery powered, so how toreduce power consumption must be considered. Low-power devices and design methods areadopted in hardware, which uses interrupt and sleep mode in software in this paper.In order to achieve the requirements of the industrial site on the reliability of datatransmission, this system’s functions are tested and analyzed; the ad hoc network functionbetween nodes and the stability of communication are verified. Wireless sensor networksdesigned in this paper has broad application prospects, which can be easily transplanted toother monitoring areas.
