FIRE DETECTING SYSTEM AND SHIP HAVING THE SAME

The present invention relates to a fire detection system and a ship having the same.

In general, when a fire occurs on a ship at sea, it can lead to a major accident and cause great casualties and property damage.

In other words, as fire and explosion accidents in ships or offshore structures cause great damage not only to property but also to human life. All possible precautions should be taken in advance.

A fire detection device for detecting whether a fire has occurred in a ship is required to detect a fire quickly when it occurs, so reliability according to accurate fire detection is required, and an ability to identify various types of fire is required.

For this purpose, the fire detector installed on the ship includes a heat detector that detects heat caused by a fire when a fire occurs, a smoke detector that detects smoke, and a flame detector that detects wavelengths in the infrared and ultraviolet regions of the flame.

As described in Republic of Korea Patent Publication No. 10-0589663 (June 07, 2006), this detector generates a signal detected by the fire detector as an audiovisual alarm, and the relay device that received the detection signal fires the worker. It operates in such a way as to deliver instructions regarding

However, in the case of the conventional fire detector described above, in the case of a smoke detector, the fire can be detected only when the smoke reaches the detector, and the heat detector also needs to be heated to a specific temperature to detect a fire, so it is difficult to suppress the fire generator early. have.
