Problems solved by technology
[0006] However, none of the above technologies can achieve simultaneous detection of seawater and the atmosphere, and the detection cycle is long, the degree of automation is low, and continuous detection is impossible. Therefore, it is necessary to design a new type of gas concentration detection system for simultaneous navigation of sea and air.

The invention provides a gas concentration detection system and method for synchronous navigation of sea and gas. The concentration detection system comprises a waterway unit and a gas analysis unit which are connected in sequence, and the waterway unit is independently and externally connected with a water collecting pipeline and a water discharging pipeline; the gas analysis unit comprises a balance membrane assembly and a laser sensor, and the balance membrane assembly and the laser sensor are circularly connected and used for carrying out gas-liquid separation on collected seawater and detecting the concentration of each gas-phase component in the gas; and the laser sensor is externally connected with a gas production pipeline. According to the gas concentration detection system provided by the invention, special working time arrangement and putting work are not needed in the scientific investigation navigation and fixed-point observation process, the continuous measurement of theconcentration of seawater or each gas component in the atmosphere is automatically completed, and the synchronous detection of the atmosphere and the seawater is realized in a short time.
Description
technical field [0001] The invention belongs to the technical field of gas detection, and relates to a gas concentration detection system and a detection method, in particular to a gas concentration detection system and a detection method for sea-air synchronous navigation. Background technique [0002] Since the industrial revolution, human life and production activities have continuously emitted carbon dioxide, methane and other heat-absorbing gases into the atmosphere, causing the radiation generated by the heating of the ground to be absorbed by the atmosphere, causing the global atmosphere to continue to warm and the ambient temperature to continue to rise . Although the content of methane in the air is very low, the insulation performance of methane is about ten times that of carbon dioxide, and methane is not easily soluble in water. As the largest "carbon sink" in the world, the ocean absorbs methane very weakly, and the marine environment Changes and acidification ...
