Problems solved by technology

[0004] Conventional detection methods include pressure gradient method, negative pressure wave leak detection method, mass or volume balance method, statistical leak detection method, acoustic leak detection method, gas method, etc. Although there are many detection methods at present, they rely on a certain detection method , can not achieve a very ideal effect, which requires more high-tech investment on the basis of conventional detection methods to develop sensitive and fast detection methods

Abstract

The invention discloses a natural gas riser early warning system based on optical fiber sensing. Damage data is collected through an optical fiber sensor in a signal collector, the damage data is stored in a centralized mode through a data concentrator, the damage data is processed through a data processor, a damage recognition module calls the damage data and judges whether the damage data exceeds a threshold value or not, and if the damage data exceeds the threshold value, an alarm is triggered; if the damage data does not exceed the threshold value, an alarm control module is not started, adisplay module receives an alarm signal output by a damage recognition signal, and image video information and sound-light reminding information of the alarm signal are displayed through an image display unit and a sound-light display unit. The natural gas riser early warning system is formed by connecting multiple modules, the structure is safe and reliable, the application range is wide, the leakage risk of a natural gas riser is reduced, the safety of people is guaranteed, losses are reduced, people and the environment are effectively prevented from suffering from unexpected harm in time,and the application range is very wide.

Description

technical field [0001] The invention relates to the technical field of pipeline optical fiber sensing, and more specifically relates to a natural gas riser early warning system based on optical fiber sensing. Background technique [0002] At present, natural gas is no stranger to our daily life. The laying of natural gas pipelines and the reservation of holes must be considered in the construction of modern urban buildings. Natural gas has entered our lives and brought great benefits to people's lives. Great convenience. However, as a combustible gas, natural gas still has the danger of explosion when it leaks, so it is very necessary to prevent and detect natural gas pipeline leakage. In the process of natural gas pipeline transportation, the parts that often leak are the connection parts, welding parts, fluid turning parts and packing sealing parts on the pipeline. [0003] Leakage of natural gas pipelines not only endangers the lives of urban residents, but also has an ...
