Description

technical field [0001] The invention belongs to the technology of accurate identification and traceability of gas leakage in chemical equipment, and in particular relates to an equipment gas leakage monitoring system and method based on artificial intelligence senses. Background technique [0002] Due to the failure of gas leakage in many fields such as pressure vessels, aerospace, gas, natural gas, etc., the losses caused are very heavy, so the monitoring method for gas leakage has become a hot topic of research at home and abroad, and monitoring gas leakage is extremely important. significance. [0003] Several main leak monitoring methods that have been used in gas leak monitoring at present mainly include: [0004] (1) Infrared imaging technology: Using the difference between the temperature field of the leakage area and the temperature field of the surrounding area, the infrared sensing image of the leakage area is obtained through image processing algorithms, so as to...

Problems solved by technology

At present, these methods are mainly used in the leakage monitoring of pressure vessels, but these methods are suitable for local defects of materials, and usually can only be repaired after the equipment is shut down, and it is difficult to achieve online monitoring, so it is more suitable for large-scale leakage monitoring difficulty

[0006] (3) Single-point monitoring and early warning of leaked gas medium: The current leaked gas monitoring is based on single-point sensors based on optical, electrochemical and other principles. Although these sensors can detect the concentration signal after an obvious leak occurs, the alarm will be issued. However, due to the relatively small amount of gas produced by early leakage, it is easy to be interfered. However, these traditional monitoring methods have the disadvantages of limited monitoring range, poor anti-interference ability of single-material selection sensors, and early warning lag. detected

[0007] A lot of research has been done on gas leakage monitoring technology at home and abroad, but they are generally limited to a specific single-level monitoring method, such as monitoring the location or amount of gas leakage alone, and lack of analysis of the gas release caused by the gas leakage process. , Infrared radiation, sound wave diffusion, temperature excursion, equipment vibration and other characteristics revealed and elaborated
