Problems solved by technology

[0003] Due to the constraints of site conditions, it is difficult to conduct a comprehensive inspection of the entire pipeline with existing detection methods. Usually, it is necessary to combine the fluid-structure interaction finite element model of the pressure pipeline for safety risk assessment: the assessment model calculates the stress and vibration state of each part of the pipeline, and uses this As a safety level evaluation indicator, the established safety evaluation model needs to be corrected in combination with actual test stress and vibration data to ensure the reliability of the safety risk evaluation results
Although there are existing stress analysis equipment and vibration analysis equipment, it is impossible to collect the stress and vibration data of each part of the entire pipeline synchronously, and the data management of each test point is complicated, and the installation of the sensor is affected by the arc shape of the pipeline, and it is also inconvenient to install. Disadvantages, in addition, the labor intensity of the test is also relatively large

Abstract

The invention relates to a long-distance overhead pipeline distributed type stress vibration on-line monitoring system and method. The long-distance overhead pipeline distributed type stress vibrationon-line monitoring system comprises a computer, a wireless data receiving module and a plurality of distributed type stress vibration data collecting nodes, wherein the distributed type stress vibration data collecting nodes are separately arranged at different positions of a long-distance overhead pipeline and are connected with the wireless data receiving module, and collected stress vibrationdata of different positions are sent to the wireless data receiving module; and the wireless data receiving module is connected with the computer and transfers the received stress vibration data to the computer for calculation storage and monitoring. According to the long-distance overhead pipeline distributed type stress vibration on-line monitoring system and method, by arranging the distributedtype stress vibration data collecting nodes, the stress vibration conditions at different positions of the long-distance overhead pipeline can be collected simultaneously, and high analytical test efficiency and data synchronism are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial pipeline detection, and relates to an operating parameter detection device for long-distance overhead pipelines, in particular to an on-line monitoring system and method for distributed stress vibration of long-distance overhead pipelines. Background technique [0002] Pressure pipelines are special equipment. Once an accident occurs, it may cause mass casualties and injuries, with great influence and strong destructiveness. The overhead pipelines in the chemical industry park are generally several or even a dozen of them are laid on the pipe gallery in a concentrated manner. If a problem occurs in one of the pipes or one part, it will cause an accident in the entire pipe gallery, and the consequences will be unimaginable. Most of the chemicals and chemical materials transported in the overhead pipeline are flammable, explosive or toxic media. The public pipe gallery in the chemical industry p...
