The invention provides a joint detection
system and method for leakage of a
carbon dioxide storage tank, a terminal and a medium, a sensor network is constructed to cover a monitoring area, and the
system comprises gas flow sensors arranged at an outlet of the
storage tank and a conveying pipeline, and a
carbon dioxide concentration sensor and a
fluorescence detection sensor which are arranged at key points around the
storage tank and the pipeline. And a trace
fluorescent tracer agent is attached to the monitoring area. Leakage is preliminarily judged according to data collected by a gas flow sensor, if leakage occurs, the data collected by a
carbon dioxide sensor and a
fluorescence sensor are utilized, a
Gaussian diffusion model and a fluid dynamic model are combined, the change direction of
fluorescence intensity and carbon dioxide concentration is calculated, a leakage point is accurately positioned, and the leakage amount is calculated. The leakage severity is judged according to the gas flow and the carbon dioxide concentration, an alarm is triggered, and the leakage point position and the leakage amount are transmitted to a control center. The
system integrates the
fluorescent tracer and various sensors, realizes real-time accurate positioning of leakage points, and has the advantages of high sensitivity, fast response, strong applicability and the like.
