Method and device for aircraft airborne environment gas automatic collection

Abstract

A method and a device for aircraft airborne environment gas automatic collection are provided. The device comprises mini air pumps, a gas sensor, an analog to digital (A / D) converter, a speed detecting circuit, a micro-processor, a storage device, a switch circuit and a wireless communication circuit which are all arranged on an aircraft. When the aircraft works, by means of timing control of the single chip, the switch circuit sequentially opens the mini air pumps, gas in high-altitude environment is sequentially collected, the collected gas passes through a gas detector, a detection parameter is input into the micro-processor through the A / D converter, the micro-converter stores gas acquisition data and speed detection data and sends the data to a ground monitoring receiver or a monitoring station through the wireless communication circuit. Preferably, the method and the device for aircraft airborne environment gas automatic collection can overcome the shortcoming of fixed point collecting errors caused by response time of the gas sensor, can acquire the environment gas data at a spatial determined position, provides basis for spatial distribution research of the environment gas, and is suitable for gas collection and analysis in the fields of safety environments, carbon emission, environment protection and the like.

Description

technical field [0001] The invention relates to a device and method for automatically collecting airborne ambient gas on an aircraft, in particular to a method and device for detecting space ambient gas suitable for high-altitude flight. technical background [0002] In the collection of ambient gas, it is often necessary to collect gas parameters at a certain height. It is an effective means to use the gas collection device carried by the aircraft to automatically collect space ambient gas. However, because the gas sensor has a certain response time when detecting gas parameters, during the flight of the aircraft, the detection data output by the gas sensor is the gas parameters that the aircraft passed by the position some time ago, and the sensor is constantly exposed to new gas parameters during the flight. It is difficult to determine the position corresponding to the detection data, which makes it difficult to study the distribution of space ambient gas. Contents of ...
