System for preventing slide misplacement caused by artificial factors

Abstract

The invention provides a system for preventing the slide misplacement caused by artificial factors. According to the technical scheme of the invention, the system is used for preventing the expansion of a slide caused by negligence. The system comprises a cabin door handle sensor used for being triggered to generate a signal upon detecting the approach of a hand towards a safety door handle, a safety door state sensor used for being triggered to generate a signal upon detecting the pull-out state of a safety plug pin, a signal processing unit used for being triggered to generate an alarm signal upon judging the triggered state of the cabin door handle sensor or the safety door state sensor, a loudspeaker used for sending an alarm upon receiving the alarm signal, and a power supply used for supplying electric power to the system. The cabin door handle sensor, the safety door state sensor, the loudspeaker and the power supply are all connected with the signal processing unit. When an airplane is provided with the above system, an alarm can be given out just in time when the safety plug pin of an emergency cabin door is pulled out or a hand approaches the safety door handle of an emergency cabin in a non-emergency situation. Therefore, the warning effect is achieved.

Description

technical field [0001] The invention relates to the field of alarm systems, in particular to a system for preventing inadvertent slide deployment. Background technique [0002] The emergency cabin door of the aircraft is used for the evacuation and evacuation of the passengers on the ground in case of an accident, and should be opened only in an emergency. The safety door of almost every civil aviation airliner is equipped with a corresponding slide assembly. Once the door is opened, the corresponding slide system will be released. After the slide is released, it must be repacked and installed in place before the aircraft is considered airworthy. However, not every airline can complete the package after the slide is released. It must be sent to a qualified aircraft parts maintenance organization. This not only wastes the precious time of other passengers, but also costs the airline tens of thousands of yuan or even The high cost of hundreds of thousands of yuan. Not only ...

AI Technical Summary

Problems solved by technology

For example, on November 13, 2015, when CA4307 (Chengdu to Guangzhou) arrived at Guangzhou Baiyun International Airport, the emergency slide at the front door was released, causing aircraft delays and major economic losses

[0003] At present, aircraft emergency doors all use the door handle and safety latch to control the opening and closing of the door, which cannot effectively prevent passengers, ground personnel, and flight attendants from , fatigue, etc.) mistakenly opened the emergency hatch, and then caused the inflatable escalator to be lowered, resulting in the accident that the plane could not take off normally

For a long time, there have been endless accidents caused by negligence, which seriously delayed flights and caused a lot of economic losses. At present, airlines have not yet found a solution to such problems.
