[Abstract]:Oil pipeline is the main transportation channel of oil and natural gas, which bears the great responsibility of energy transportation. Pipeline all over the country, its safety situation will be pipeline companies, government departments at all levels, all sectors of society focus. However, due to geological hazards or man-made damage, oil pipeline subsidence, displacement and even fracture occur from time to time, the abnormal displacement monitoring of oil pipeline is very necessary. As a new modern space positioning technology, GPS has replaced the traditional optical and electronic measurement methods in many fields of measurement, and the realization of deformation monitoring in the field of deformation monitoring can reduce the workload of field work. Greatly improve working efficiency [1]. Based on these advantages of GPS, this paper considers the application of GPS measurement technology in the field of oil pipeline displacement monitoring. In this paper, the GPS static relative positioning method is used to locate the oil pipeline, the principle of the static relative positioning method is expounded, and the influence of various errors on the static relative positioning in the abnormal displacement monitoring of the oil pipeline is analyzed. This paper also studies the key technology of static relative positioning in the application of displacement monitoring, gives a method that can accurately detect the whole cycle jump and gross error of observation value, and studies the problem of determining the ambiguity of whole cycle. In this paper, a method for fast searching for integer ambiguity is presented. In this paper, the complete algorithms from the observation data processing to the final location of the oil pipeline are presented, and these algorithms are implemented by programming. In this paper, the accuracy and validity of the algorithm are verified by using the observation data of the IGS station to verify the localization results, error analysis and comparison with the exact coordinates.
