摘要	气体的检测方法多种，如：电化学方法、半导体方法、红外方法、红外成像方法、激光方法等等。不同的方法均有不同的优点及缺点，不同的精度等级，以及不同的使用环境。在许多工业过程中，压力容器被广泛使用，例如化工、石油、食品加工等行业。压力容器的内部压力和气体密度是重要的参数，直接影响到生产过程的安全和效率。然而，需监测的压力容器在阀门处安装机械压力表，需人工按时巡查压力，压力数据无法实时获取，从而导致气体泄漏或无法及时更换补充气源等现象，或由于环境温度升高而使钢瓶超压并发生爆炸事故等。在压力容器内的气体纯度不高，或是充装气体为混合气体时，由于气体密度的计算与气体摩尔质量数据、气体常数相关，还与压力容器所在环境的温度相关，在此场景下，现有的监测系统往往不能实时准确监测气体密度，对压力容器的稳定运行存在一定的风险。在线气体监控系统可以更加实时高效的发现这些泄漏风险。
Abstract	There are many detection methods of gas, such as: electrochemical method, semiconductor method, infrared method, infrared imaging method, laser method and so on. Different methods have different advantages and disadvantages, different accuracy levels, and different use environments. Pressure vessels are widely used in many industrial processes, such as chemical, petroleum, food processing and other industries. The internal pressure and gas density of the pressure vessel are important parameters, which directly affect the safety and efficiency of the production process. However, the pressure vessel to be monitored is installed with a mechanical pressure gauge at the valve, which requires manual inspection of the pressure on time, and the pressure data cannot be obtained in real time, resulting in gas leakage or failure to replace the supplementary air source in time, or overpressure of the cylinder and explosion accidents due to rising ambient temperature. When the gas purity in the pressure vessel is not high, or when the gas is filled with mixed gas, the calculation of gas density is related to the gas molar mass data and gas constant, as well as the temperature of the environment where the pressure vessel is located. In this scenario, the existing monitoring system often cannot accurately monitor the gas density in real time, which poses certain risks to the stable operation of the pressure vessel. Online gas monitoring systems can detect these leakage risks more efficiently and in real time.
