Key Technologies Research of Remote Monitor System on Oil-gas Production
Yuan Hai-yan · Jisuanji gongcheng · 2009
Analysing present situation of oil and gas production and defect of present monitor control system, three-ties architecture is presented. Terminal subsystem is the first layer, which is mainly made of RTU, flow computer, wireless sensor network. The Second layer is security transmission subsystem, which is made of GPRS(CDMA)+APN. The last layer is centre monitor subsystem, which is exchange platform based on virtual data centre. Four key technologies are applied to the remote monitoring system. As a result, work efficiency of oil-gas production has been greatly increased, and safety accidents have been reduced.
