The embodiment of the invention relates to an air quality monitoring system applied to an aircraft. The system comprises an air pipeline with one end connected with an inlet of the air monitoring system, an air quality monitoring unit with the air inlet end connected with the air pipeline, an air flow meter which is used for setting and measuring the air flow passing through the air monitoring unit, a first sucking pump which is connected with the air outlet end of the air flow meter and used for sucking air in the air pipeline so that the air in the air pipeline can sequentially pass throughthe air monitoring unit and the air flow meter, a second sucking pump which is connected with the other end of the air pipeline, a pressure sensor, and a control unit which is used for controlling therotating speed of the second sucking pump according to the change of the atmospheric pressure and the air flow measured by the air flow meter so as to change the air flow in the air pipeline, and controlling the rotating speed of the first sucking pump according to the air flow measured by the air flow meter so as to keep the air flow passing through the air monitoring unit constant.
Description
technical field [0001] The embodiments of this specification relate to the field of air detection, and in particular to an air quality monitoring system applied to an aircraft and the aircraft. Background technique [0002] There is air on the earth, and the air contains a variety of gases, which are also emitted in various activities carried out every day. These emitted gases may pollute the air, so it is very important to monitor the air quality. Through the monitoring of air quality, we can know the content of various gas components in the air, such as sulfur dioxide, nitrogen oxides, etc., so that we can take targeted measures. [0003] The monitoring of air quality is not only the monitoring of the air on the surface of the earth, but also the monitoring of the air quality at high altitudes. Since the air pressure on the earth's surface is different from the air pressure at high altitudes, corresponding monitoring instruments are required to monitor the air at high alt...
