Natural gas pipeline leakage monitoring and management safety system

Abstract

The invention discloses a natural gas pipeline leakage monitoring and management safety system comprising a data acquisition system, a data communication system and a central analysis and treatment center. A high-sensitivity pressure transmitter, a flowmeter and temperature sensors are electrically connected with an MCU, the high-sensitivity pressure transmitter is arranged in a pipeline, one end of the flowmeter is arranged in the pipeline, and the temperature sensors are arranged inside and outside the pipeline; and the data acquisition system transmits acquired data to the central analysis and treatment center through the data communication system, and the central analysis and treatment center analyzes and calculates the data information. The natural gas pipeline leakage monitoring and management safety system is low in installation cost, only the data acquisition system needs to be arranged at the head end and the tail end of the pipeline, and sensors do not need to be arranged on everywhere of the pipeline, so that the low cost and the large coverage rate are guaranteed; real-time monitoring can be realized, the leakage time can be rapidly determined through the high-sensitivity pressure transmitter once manual damage occurs, and meanwhile, the position of the leakage point is rapidly calculated according to the combination of the high-sensitivity pressure transmitter, the flowmeter and the temperature sensors.

Description

technical field [0001] The invention relates to the field of natural gas pipelines, in particular to a natural gas pipeline leakage monitoring management safety system. Background technique [0002] Pipelines that transport natural gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users are also called gas pipelines. The use of natural gas pipelines to transport natural gas is the only way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length. [0003] Existing gas pipelines are assembled one by one by connecting single pipes. Modern gas gathering pipelines and gas transmission pipelines are made of steel pipes connected by electric welding. There are many kinds of steel pipes, such as seamless pipe, spiral seam pipe and straight seam pipe. The seamless pipe is suitable for pipes with a diameter of less than 529mm, and the spiral seam pipe ...

Problems solved by technology

[0005] The existing gas pipeline system can only carry out monitoring and early warning at designated locations. Due to the wide coverage of the pipeline, if the middle part of the pipeline is damaged by man-made damage, timely warning and timely repair cannot be performed, which will cause more serious environmental pollution and danger.

At the same time, if the sensors are densely distributed near the pipeline, the cost will be high and it will not be popularized.
