Embodiment

[0056] Embodiment. This example is an industrial prototype, which is tested between stations of a certain pipeline 30km. The pig monitoring system is composed of multiple pig tracking and positioning receivers and a data management center, and is realized by using a mobile communication network and GPS satellite positioning system; multiple pig tracking and positioning installed on buried pipelines The receiver communicates with the data management center through the mobile communication network, and the GPS timing module connected with the GPS satellite is connected to the tracking and positioning receiver

[0057] Prototype industrial test systems such as Figure 11 , 5 sets of prototypes were installed in pig starting station, receiving station, RTU valve room, non-RTU valve room and field. The prototype obtains time information from GPS satellites, and the time of the prototype is calibrated at regular intervals according to the requirements of time accuracy. The data ma...

Abstract

The invention is an on-line tracking and positioning system for a pipeline pig. It relates to the technical fields of measuring magnetic variables, mechanical vibration measurement and piping systems. It consists of multiple pig tracking and positioning receivers, a mobile communication network, a data management center, and a GPS timing module; multiple pig tracking and positioning receivers installed on the buried pipeline communicate with the data management center through the mobile communication network. Contact, the GPS timing module connected with GPS satellites is connected to the data management center. The invention is all-weather, unattended, stable and reliable, and widely applicable.

Description

technical field [0001] The invention is an online tracking and positioning system for a pipeline pig. The invention relates to the technical fields of magnetic variable measurement, mechanical vibration measurement and pipeline system. Background technique [0002] Pigging operation is an important task before or during the operation of long-distance oil and gas pipelines to ensure the normal operation and transmission efficiency of the pipeline. For new pipelines, the main purpose of pigging is to remove various sundries in the pipeline; for pipelines that have been put into operation, the purpose is to remove wax, scale, water and dust. In recent years, intelligent pigging (internal detection) technology has developed rapidly, and its results provide a strong theoretical basis for pipeline integrity evaluation and pipeline renovation. [0003] The pig is an important equipment in the pigging operation, and it is extremely important to prevent it from being blocked. At p...
