METHOD OF THE PIPELINE CHARACTERISTICS DETERMINATION (VARIANTS) AND COMPLEX FOR ITS IMPLEMENTATION AND PIPELINE DAMAGE DETECTION

摘要

The complex contains two pairs of sensor 2 pressure in the pipeline 1, installed in pairs at a distance of 50-200 meters between neighboring sensors 2 in each pair, the local programmable logic controllers, 3 sensors timestamp in the form of GPS receivers 4, line 5 context, the central controller 6 and workstation operator 7 (PC 7). The sensors 2 are satisfied with the response time of less than 1 ms (milliseconds). A pair of sensors 2 are located on the borders of the control section of the pipeline I5 the distance between two pairs of sensors, i.e., length control region is 5000 - 50 000 m. Thus, the sensor 2 is installed at a distance between them at each end of the control region of between 0,001 to 0.04 the length of this section of the pipeline 1. One of the two sensors in each pair is internal to the control site, while another - the outside. Ratio of distances between sensors 2 in each pair and the length of the chosen from the condition of minimal influence of hydraulic losses along the length of the site on testing results. The technical result of the invention group combined with the unique invention idea lies in extension of the functional possibilities, increase of the technological effectiveness, simplification of the design, increase of accuracy, reliability and operation speed at the account of the efficient and online control of the wave parameters at the stage of its occurrence, control of the fluid medium parameters on a real-time basis, and leakage detection at the stage of its occurrence on a real-time basis.
