いので、安全上問題がある。BACKGROUND OF THE INVENTION The engine room of a conventional ship is generally equipped with a fire detector and a carbon dioxide fire extinguishing system or a foam fire extinguishing system. When the fire detector goes off,
An alarm is issued on the bridge, and if the ship is equipped with a carbon dioxide fire extinguishing system, carbon dioxide gas will be ejected from all extinguishing agent outlets into the entire space in the engine room by manual remote control from the bridge, and if the ship is equipped with a foam fire extinguishing system. Then, the crew goes to the fire extinguishing system location and operates the pumps and valves to spray foam from all extinguishing agent outlets to the entire target area in the engine room. However, carbon dioxide gas fire extinguishing equipment and foam fire extinguishing equipment each have their advantages and disadvantages.
Providing only one type of equipment is problematic. In addition, in the case of any fire extinguishing system, if the fire detector is activated, extinguishing agent will be squirted from all extinguishing agent spouts even if the fire is small, so not only will the extinguishing agent be wasted; , there is a risk of harm to the crew. Further, since there is a manual operation step between the activation of the fire detector and the activation of the fire extinguishing system, there is a time loss and such manual operation is required. Furthermore, there is a safety problem because only a warning is issued without proper evacuation guidance.

次に、第２図のフローチャートを参照して、機関室−に
火災が発生したときのこの発明による消火方法の１例を
説明する。Next, an example of the fire extinguishing method according to the present invention when a fire occurs in an engine room will be explained with reference to the flowchart of FIG.
制御装置は、機関室翰内の全ての火災検知器の出力を常
時監視しくステップ１）、いずれか１の検知器が作動し
たか否か、すなわち火災が発生したか否かを判断する（
ステップ２）。そして、火災が発生して検知器が作動し
たときに、作動している検知器の数により火災の規模を
自動的に判定する（ステップ３）。すなわち、機関室翰
内の全検知器の一定割合（たとえば８０チ）を越える数
の検知器が作動している場合には大規模火災と判定し、
この割合以下の数の検知器が作動している場合には小規
模火災と判定する。なお、火災規模の判定基準は、種々
の条件を考慮して適宜決定すればよい。The control device constantly monitors the output of all the fire detectors in the engine room window (Step 1), and determines whether any one of the detectors has activated, that is, whether a fire has occurred (
Step 2). Then, when a fire occurs and the detectors are activated, the scale of the fire is automatically determined based on the number of activated detectors (step 3). In other words, if more than a certain percentage (for example, 80) of all detectors in the engine room are operating, it is determined that it is a large-scale fire.
If the number of detectors below this ratio is activated, it is determined that it is a small fire. Note that the criteria for determining the scale of a fire may be appropriately determined in consideration of various conditions.
大規模火災と判定した場合、制御装置は、炭酸ガス消火
装置および泡消火装置の全ての消火剤噴出口から自動的
に炭酸ガスおよび泡を噴出する（ステップ４）。If it is determined that the fire is a large-scale fire, the control device automatically spouts carbon dioxide gas and foam from all extinguishing agent outlets of the carbon dioxide gas extinguishing system and the foam fire extinguishing system (step 4).
小規模火災と判定した場合、制御装置は、作動している
検知器の位置により火災発生場所を自動的に判定しくス
テップ５）、この判定結果に基づいて次のように消火装
置を制御する。If it is determined that it is a small-scale fire, the control device automatically determines the location of the fire based on the position of the activated detector (step 5), and controls the fire extinguishing system as follows based on this determination result.
空間火災検知器および床火災検知器が両方とも作動して
いるときには、空間および床火災と判定し、火災発生場
所すなわち作動している検知器に対応する炭酸ガス消火
装置および泡消火装置の消火剤噴出口から自動的に炭酸
ガスおよび泡を噴出する（ステップ６）。When both the space fire detector and the floor fire detector are activated, it is determined that the fire is a space or floor fire, and the extinguishing agent in the carbon dioxide fire extinguishing system and foam fire extinguishing system corresponding to the location of the fire, that is, the activated detector. Carbon dioxide gas and bubbles are automatically spouted from the spout (step 6).
空間火災検知器だけが作動しているときには、空間火災
と判定し、作動している検知器に対応する炭酸ガス消火
装置の消火剤噴出口から自動的に炭酸ガスを噴出する（
ステップ７）。When only the space fire detector is activated, it is determined that there is a space fire, and carbon dioxide gas is automatically spouted from the extinguishing agent spout of the carbon dioxide fire extinguishing system corresponding to the activated detector (
Step 7).
床火災検知器だけが作動しているときには、応
床火災と判定し、作動している検知器に対９する泡消火
装置の消火剤噴出口から自動的に泡を噴出する（ステッ
プ８）。When only the floor fire detector is operating, it is determined that it is a floor fire, and foam is automatically spouted from the fire extinguishing agent spout of the foam extinguishing system corresponding to the operating detector (step 8).
制御装置は、上記めように消火装置を制御すると同時に
、火災の規模と場所に応じて自動的に避難路を決定して
これに対応する録音テープを選択し、機関室翰、居住区
などのスピーカを使用して、たとえば「機関室内の後部
が火災のため、前方の階段を使って上甲板の扉から外部
へ避難されたし。」というような避難誘導放送を行なう
（ステップ９）。The control device controls the fire extinguishing system as described above, and at the same time automatically determines the evacuation route according to the scale and location of the fire, selects the corresponding recording tape, and fires the evacuation route in the engine room, living area, etc. A speaker is used to make an evacuation guidance announcement such as, ``There is a fire in the rear of the engine room, so please evacuate to the outside through the upper deck door using the front stairs.'' (Step 9).
上記の一連の動作は、火が消えて全ての火災検知器が作
動しなくなるまで繰返して行なわれる。そして、消火作
業中にたとえば床火災が空間および床火災に拡がったよ
うな場合には、最初はステップ８の動作を行なうが、空

模火災に拡がったような場合には、最初はステップ６．
７または８の動作を行なうが、大規模火災になった時点
からステップ４の動作を行なう。これらと逆の場合も同
様である。The above series of operations is repeated until the fire is extinguished and all fire detectors are no longer activated. If, for example, a floor fire spreads to a space and a floor fire during the fire extinguishing operation, step 8 is performed at first, but once the space and floor fire has occurred, step 6 is performed. Similarly, if during a firefighting operation, for example a small fire spreads to a large fire, first step 6.
Perform step 7 or step 8, but perform step 4 from the moment a large-scale fire occurs. The same applies to the opposite case.

な噴出を防ぐことができる。As described above, according to the fire extinguishing method of the present invention, when a fire breaks out in the engine room, the activation of the fire extinguishing system and appropriate evacuation guidance can be carried out quickly without the need for manpower. It is possible to improve the safety of ships with fewer crew members. Furthermore, when the scale of the fire is small, the extinguishing agent is spouted only from the extinguishing agent spout corresponding to the location where the fire occurred, so it is possible to prevent unnecessary spouting of extinguishing agent as in the past.
