Research on Oil well Remote Monitor System Based on Beidou Satellite Technology and LabVIEW Fang QiZhia, Zhao JianMinb and Sun YanPengc College of Electronics and Information Engineering, ShenYang Aerospace University ShenYang, China aarinc2006@tom.com, b, c sunyanpeng@163.com Keywords: Oil well; RTU; Beidou satellite; LabVIEW Abstract: The distribution of oil Wells is mainly in the field or by sea, most of the oil Wells are using human inspectors for condition monitoring, the problems of this are low efficiency and lack of real-time monitoring.
In addition, double sending policy is adopted when sending data, if confirmation of receiving is not gained within the specified time from first sending, the same data will be send again automatically. [5] Considering the restrictions on civil use of the big-dipper communication, automatic retransmission is set for 2 times.
