Smoke detection system and aircraft with same

Abstract

The invention relates to a smoke detection system and an aircraft with the same. The smoke detection system comprises a smoke detection device and a plurality of temperature measuring devices. The smoke detector is arranged in the cabin and is used for sensing the smoke concentration in the cabin and sending out smoke alarm information. The temperature measuring devices are arranged in the cabin and used for sensing the temperature in the cabin. When the temperature sensed by at least one temperature measuring device reaches or exceeds a preset temperature value, the ventilation device of the cabin is controlled to stop ventilation. According to the invention, the smoke detector is directly arranged in the cabin of the aircraft, so that the smoke detector is prevented from being installed in the ventilation pipeline to influence ventilation airflow, and the smoke detector is prevented from sucking dust in the ventilation pipeline to cause false alarm.

Description

Technical field [0001] The present invention relates to the field of civil aviation, and more particularly to a smoke detection system and aircraft having it. Background technique [0002] Civil aircraft has specialized electronic equipment cabins for installing electronic devices and provides a normal working environment. A large amount of heat is generated during the operation of the electronic equipment, accumulating in the closed space of the electronic equipment cabin, causing increased temperature in the cabin. In order to avoid overhevation, a ventilation system is also provided to generate air flow between the electronic equipment cabin and the outside to achieve cooling. [0003] In addition, a smoke detector is generally arranged in the cabin of the electronic device. The smoke detector can sense the smoke concentration in the cabinet, and a smoke alarm is issued when the smoke concentration exceeds the set threshold. Considering that there is ventilation in the cabin, ...
