[0002] With the rapid development of industrial production today, gas leakage has become a major safety hazard faced by the chemical, petroleum, pharmaceutical and other industries. As an important gas storage equipment in the industrial field, the safety of gas tanks is of vital importance. However, in actual applications, gas leakage problems in gas tanks often occur, posing a serious threat to the production safety of enterprises and the safety of life and property of personnel. The traditional method of detecting gas leakage in gas tanks mainly relies on manual inspections, which is not only inefficient, but also difficult to ensure the accuracy and timeliness of detection. In addition, manual inspections are also easily affected by human factors, such as the experience, skills and sense of responsibility of the inspectors, resulting in missed inspections or false alarms from time to time. In addition, traditional detection methods are often unable to monitor gas leakage in real time and accurately, making it difficult to provide effective protection for the safe production of enterprises.
