Loses The Pipe Network Branch Divulging Examination System Research

Pipeline based on the hypothesized instrument collection divulging to be able to bring the heavy economic loss not merely, creates the resources the waste, moreover acts according to in the pipeline to ship material the difference, but also can cause the serious harm to the environment, even can endanger to people's life. Therefore, the various countries all extremely take to prevent the pipeline effectively divulging, how effectively surveys the pipeline promptly divulging, locates the leaking point accurately, since becomes key point which the various countries have studied continuously. In initiation oil pipeline divulging accident all sorts of reasons, the artificial destruction pipeline steals the petroleum the situation to be most serious. Robs the oil is in our country oil field construction special question, the solution unlawful element punch robs the oil the technical key is: Pipeline divulging examination and pinpointing. Therefore, discovered promptly the oil leak accident and the accurate localization, regarding rapidly adopts the loss which the measure, the reduced accident create, is in the oil field construction and the management is extremely essential and the urgent problem, also has the extremely remarkable social efficiency and the economic efficiency. The present paper in the investigation and study and in the consult material foundation, had condition and so on time divulging pressure, current capacity to the oil pipeline changes has conducted the research, has analyzed the pipeline had when divulging its corresponding parameter change rule; Has analyzed in the pipeline fluid temperature the rule and to the pipeline in which changes along with the transmitting range the negative pressure wave speed influence; Uses the pressure, the current capacity union distinction method, unifies the pipeline both sides to receive the negative pressure wave the time difference, carries on the examination and divulging to pipeline divulging designates the position; Uses the duplicate Simpson formula the pipeline in negative pressure wave velocity formula to carry on the transformation; Uses the wireless wide frequency networking to carry on the sampling data transmission; And in order to locate accurately, uses GPS to unify the first terminal data acquisition system the system time; To divulges the examination localization software system to make the improvement. Finally, through was being near aids the line to install debugs and moves, has realized auto-alarm and to robs the oil position the localization. After the proof improvement pipeline divulging monitor and the positioning system may discover divulging fast, determined divulges the position, enhanced the divulging examination localization speed and the accuracy.
