METHOD FOR DIAGNOSIS OF TECHNICAL STATE OF INTERSECTIONS OF GAS PIPELINES AND SYSTEM FOR ITS IMPLEMENTATION

摘要

FIELD: machine building.;SUBSTANCE: linear deformation magnitudes D1(t), D2(t) of pipeline crossing at time t are measured to monitor compliance of measured values with appropriate ranges of tolerable values (Dh1…Db1), (Dh2…Db2), and, in case at least of measured value D1 (t) or D2(t) falls beyond appropriate range of tolerances, dangerous state is taken to exist. Proposed system comprises m strain gages, m ADCs, microprocessor and means of communication with dispatcher station on each pipeline crossing. Note here that axes of strain gages are directed along pipeline whereon they are mounted. Output of each gage is connected via appropriate ADC to microprocessor and the latter is connected to means of communication with dispatcher station (m= 1,2,3…).;EFFECT: higher reliability of control.;7 cl, 3 dwg
