METHOD AND SYSTEM FOR TRACKING motion path pigging

摘要

1. A method for tracking the motion of the projectile in-tube at kotoromsnaryad inside the pipeline is measured by a measuring system in the projectile physical magnitude characterizing the state and / or characteristics of the projectile and / or the conduit, and write them into data memory projectile with reference to the time determined by projectile hours; on the outside of the pipeline by means of at least one DVR is installed near the control point of the pipeline, measured magnetic field strength or other fizich skie values ​​that identify the passage of the projectile near the recorder, with reference to the time determined by the clock recorder, and based on said measured physical quantities and their corresponding time values ​​forming characteristics allowing identification points projectile passing time near the registrar by the hour recorder, and recording the generated characteristics in the recorder data storage, and during passage of the projectile within the pipeline from a transmitter raspolozhennog on one of the pair of objects, consisting of a projectile and registrar, transmits a signal with a time characteristic associated with the readings of clock on the side of said transmitter; receiving a transmitted signal with a time characteristic to a receiver located in the other of said pair of objects, and is recorded in the storage device storoneupomyanutogo data to the receiver at least one characteristic associated with the time characteristic of the received signal with reference to the clock on the side of said receiver determined by difference
