Description

ORGANIC COMPOUND DETECTION DEVICE FOR AIRCRAFT COCKPIT

The present invention relates to an organic compound detecting device, and more particularly, to an organic compound detecting device for an aircraft cockpit capable of detecting a volatile organic compound inside an aircraft cockpit to warn an aircraft pilot of a danger.

Volatile Organic Compounds (VOCs), which are rapidly increasing in the living environment, have adverse effects on the human body by causing skin diseases such as atopy and cancer. In particular, Volatile Organic Compounds (VOCs) that are harmful to the human body such as formaldehyde (Methanal) and benzene (Benzene) are also generated in the exterior walls of newly produced aircraft.

These volatile organic compounds (VOCs) are organic compounds that normally exist in a gaseous state at room temperature and atmospheric pressure. However, the present invention is not limited thereto, and all organic compounds ionized at energy of a specific amount (eg, 9 eV, etc.) may be included.

In the case of a VOC sensor for detecting volatile organic compounds, there are generally a photoionization (PID) method and a semiconductor-type resistance change method, and recently, an ionization method using emission electrons has been proposed.

In particular, the above-mentioned toxic substances may cause symptoms such as irritation of the upper respiratory tract and mucous membranes, headache, difficulty concentrating, irritability, nausea and drowsiness. These symptoms are particularly fatal for air missions that require a high degree of concentration.

Therefore, as a countermeasure for the safety of the pilot and the effective performance of the mission, the precise necessity of detection according to the generation of organic compounds in the cockpit of an aircraft and the presentation of a technology for effectively informing the pilot of the cockpit are required.
