Definitions

  • the invention relates to devices for monitoring the status of pipelines, and in particular to a method and device for tuning a measuring system of an in-line flaw detector.
  • Data from the measuring sensors are read after the sensor has traveled a certain distance.
  • the measuring system of the in-tube flaw detector at certain time periods, which depend on the speed of the flaw detector inside the pipe and the required accuracy of readings, reads data from the sensors.
  • Transverse “scans” are data readings from a group of sensors taken at certain time periods. Longitudinal “scans” - data readings taken from one sensor after certain periods of time. As indicated above, time periods are associated with the path traveled by the flaw detector inside the pipe.
  • Skipping one or more scans in the longitudinal direction leads not only to skipping the defect, but also to incorrect binding measurements along the length of the pipe, which is unacceptable.
  • a skipping reference in the longitudinal direction may be due to a malfunction of the odometer sensor, poor condition of the contacts in the connectors, a malfunction in the hardware and software of the flaw detector measuring system, and other reasons. Therefore, the functioning of the entire measuring system of an in-line flaw detector, from the point of view of constructing a grid of samples in time, along the length of the pipe being studied, is an important task and is checked before measurements.
  • Known tuning systems of the measuring system of an in-line flaw detector operate as follows.
  • the cable leading from one of the sensors is disconnected and, instead of an odometer sensor, to a flaw detector, a pulse generator is connected to the connector, giving out pulses with the speed of the flaw detector, thus simulating the movement of the flaw detector inside the pipeline.
  • the flaw detector control system receives impulses from the odometer and accordingly generates impulses for starting measurements.
  • the operator checking the flaw detector approaches and removes to one (or several) sensors of the measuring system a signal simulator, for example, a permanent magnet for a magnetic flaw detector. As a result, the flaw detector records changes in the magnetic field.
  • the operator After completion of the pass simulation, the operator connects the flaw detector to an external terminal and receives the flaw detector measurement results in the form of a dependence of the magnetic field level on the sensor that was exposed to the magnetic field.
  • the same type of measurement is made for ultrasonic flaw detectors.
  • the application describes a tuning method, including sequentially calibrating the output signal levels of sensors measuring the profile of the inner wall of the diagnosed pipeline using a calibration ring. This calibration is carried out by rotating the calibration ring relative to the measuring system of the flaw detector or by rotating the measuring system relative to the calibration ring.
  • the main technical problem solved by the claimed invention is the ability to check the entire measuring system of the in-line flaw detector.
  • the inventive verification method and the verification device are simple and effective, providing the ability to verify not only the formation of readings, but also verify the operation of all measuring sensors of the system.
  • the inventive method of tuning the measuring system of an in-line flaw detector containing an odometer and measuring sensors is characterized in that the measuring wheel of the odometer is rotated synchronously with the movement of one or more calibration means relative to one or more measuring sensors of the measuring system. Register data from the measuring sensors and compare the measured data with the control data.
  • the odometer wheel When performing the method, it becomes possible to check the entire measuring system of the in-line flaw detector. It is not necessary to disconnect the odometer, on the contrary, the odometer wheel, as in the real work of the system, rotates at the required speed and the odometer sensors generate start pulses of the measurement system. Moreover, due to the synchronous rotation of the odometer wheel and the movement of the calibration means, the data obtained during normal operation of the flaw detector measuring system are rigidly determined by the position of the odometer wheel and the associated position of the calibration tool. Any failure of the measurement system is easily detected.
  • the calibration means or several calibration means are moved by rotation relative to one or more measuring sensors.
  • the tuning device of the measuring system of an in-line flaw detector containing an odometer and measuring sensors includes a roller driven by a motor and mounted with the possibility of contact with the odometer wheel, and a ring with calibration means.
  • the said ring is installed with the possibility of movement, in the particular case of rotation, relative to one or more measuring sensors of the measuring system of the flaw detector.
  • the axis of said roller and the axis of said ring with calibration means are rigidly interconnected.
  • the tuning device comprises a roller that rotates from the engine at a fixed speed and necessary for checking, and a ring with calibration means that rotates synchronously from the same engine. Since the rotation of the odometer wheel is tightly synchronized with the rotation of the ring with calibration means, the readings of the measuring sensors are monitored not only from the point of view of accuracy and the absence of missing samples in time, but also from the point of view of the functioning of the sensors themselves, for example, monitoring their sensitivity. In the particular case of the device, the rigid connection of the axis of said roller and the axis of said ring with calibration means is made by means of a flexible shaft.
  • FIG. 1 and FIG. 2 shows a diagram of a device for tuning the measuring system of an in-line flaw detector
  • FIG. 3 is a diagram of samples (scans) in time
  • FIG. 4 - grid of readouts (scans) on the surface of the pipeline.
  • the measuring system of the in-line flaw detector checked by the present method, can be of various designs, for example, with magnetic or ultrasonic sensors. In the example shown in the figures, the operation of the method and device with a magnetic flaw detector system is considered.
  • the in-tube flaw detector 1 (Fig. 1) contains an odometer 2 with a wheel 4 and measuring sensors 3.
  • the tuning device (Fig. 1 and Fig. 2) of the in-tube flaw detector measuring system 1 includes a roller 6, which is driven by engine 7.
  • a roller 6 is installed with the possibility of contact with the wheel 4 odometers.
  • Ring 8 with calibration means 5 is mounted rotatably relative to one measuring sensor 3. Nearby standing sensors, not shown in the figure, can also be checked. You can make the ring so that it rotates around all the measuring sensors of the measuring system of the flaw detector.
  • the axis 11 of the roller b and the axis 10 of the ring 8 with the calibration means 5 are rigidly interconnected by means of a flexible shaft 9. Permanent magnets can be used as calibration means for magnetic sensors. If the operation of the system with ultrasonic sensors is checked, ultrasonic emitters can be used.
  • the setup device operates as follows.
  • the odometer wheel 4 is supported by a roller 6, which rotates from the engine 7. From the same engine 7, the wheel 8 rotates synchronously with the flexible shaft 9 with the calibration means 5 installed on it, in this case magnets. Magnets act on the magnetic sensor 3, which, on the command of the measuring system, which is formed on the readings of the sensors of the odometer 2, takes readings. Since the rotation of the wheel 4 of the odometer 2 and the position of the calibration means 5 are rigidly determined, comparing the measured data with the control data makes it possible to configure the measuring system.
  • the application of the proposed method and device uniquely connects the impact on the odometer (speed change) with the impact on the sensors of the flaw detector measuring system, which makes it possible to evaluate the stability of the scan grid in the entire range of flaw detector speeds.
