Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, specifically to an intelligent pipeline sampling gas monitoring system. Background Technology

[0002] While there are many mature industrial gas sampling, analysis, and monitoring systems on the market, they generally lack the ability to intelligently and precisely allocate system resources. When a problem arises at one or more monitoring points, the system simply follows the established procedure, sampling and inspecting all monitoring points in a round-robin manner. It fails to concentrate resources and focus on the suspicious points with high intensity and frequency, thus increasing the time window for problem detection and reducing the efficiency of problem repair.

[0003] Secondly, current pipeline sampling and analysis systems generally use a single analyzer, which is costly and lacks flexibility. Furthermore, industrial production analysis cabinets on the market typically use wired networks to transmit data, which not only increases cabling costs but also reduces system efficiency.

[0004] Therefore, to address the aforementioned issues, an intelligent pipeline sampling gas monitoring system is designed to automatically monitor the gas within industrial pipelines and automatically allocate detection resources. Furthermore, by incorporating various gas analyzers and gas detectors into this system, the applicability is expanded, costs are reduced, and the system's flexibility is greatly increased, making it essential for those skilled in the art.
