Problems solved by technology

[0003] At present, the leakage monitoring methods of organic hazardous chemicals used in chemical industry parks are mainly divided into two categories: one is to arrange electrochemical, catalytic combustion, and laser spectroscopy monitoring sensors in key areas of the park, and perform leakage identification according to preset alarm thresholds The alarm can not directly reflect the spatial distribution of the leakage of organic hazardous chemicals, the accuracy rate is low, and the false alarm rate is high; the other is to realize the visual imaging of organic hazardous chemical leakage through gas optical imager, which requires manual operation to identify organic hazardous chemicals Product leakage, labor-intensive and unable to realize automatic intelligent identification, low efficiency, low accuracy, difficult to meet the needs of real-time online monitoring
