Embodiment 1

[0023] The gas pipeline safety early warning system disclosed in the present invention includes a main station system and a substation system; the main station system in this embodiment includes a data processing system and a waveform display terminal, and the substation system includes a data acquisition system, a preamplifier, and GPS timing Module in which the data acquisition system is connected with the data processing system. In this embodiment, the data acquisition system includes an acoustic wave sensor, a pressure sensor, and a gas detection sensor.

[0024] In this embodiment, the acoustic wave sensor is divided into two parts, an infrasonic wave sensor and an acoustic wave sensor. The infrasonic wave sensor is used to receive the sound wave signal inside the pipe, and the acoustic wave sensor is used to receive the sound wave signal outside the pipe. Converted into electrical signals.

[0025] The infrasonic wave sensor and the acoustic wave sensor are respectively conn...

Abstract

The invention relates to the field of fuel gas pipeline monitoring, in particular to a fuel gas pipeline safety early-warning system which comprises a main station system and a substation system. The main station system comprises a data processing system and a waveform display terminal connected with each other; and the substation system comprises a data acquisition system; and the data acquisition system is connected with the data processing system. The data processing system comprises a sonic wave sensing part, a pressure sensor and a gas detection sensor; and the sonic wave sensing part comprises a sonic wave sensor and a subsonic wave sensor. According to the fuel gas pipeline safety early-warning system provided by the invention, by utilizing the combination of multiple ways of sonic wave sensing and pressure and gas sensing, whether leakage occurs or not, the type of the leaked gas and the position information of leakage occurrence can be accurately and timely judged, so that an accurate judgement basis and safety early-warning are provided for safety monitoring personnel.

Description

Technical field [0001] The invention relates to the field of gas pipeline monitoring, and a gas pipeline safety early warning system and method for specific locations. Background technique [0002] In recent years, the gas pipeline network has developed rapidly. The gas pipeline network has been densely arranged underground in the city. In the process of urban construction, underground excavation, underground construction and other reasons cause frequent damage to the underground gas pipeline network. Therefore, pipeline safety warnings It is especially important. In particular, some old pipelines are mostly made of metal for transmission. Because they are buried in the ground for a long time, the pipelines are easily corroded. The walls of the pipelines are thinned or perforated, which will cause the pipeline to rupture and leak, and even cause accidents such as explosions, which will cause the country and the people. A huge loss of life and property. Especially for pipelines ...
