For example, when a fire in the EMDG chamber 200 is detected by the first sensing unit and the second sensing unit, the second control unit 20 closes the fire damper 60 (S20) (40) operates the local fire fighting equipment (30), and sprays the microfluidized water to the EMDG chamber (200) through the microfluidic water supply pipe (31) (S30). Also, the second control unit 20 controls the crew to notify occurrence of a fire, for example, through a warning lamp or a warning sound.

Next, the first sensing unit mounted on the EMDG chamber 200 senses the state of the EMDG chamber 200 (S40). That is, the detection of the fire as described above is executed according to the variation of heat or smoke in the EMDG room 200 or the EMDG room 300 or the like.

If it is determined in the first sensing unit that the fire in the EMDG chamber 200 is not executed, that is, when the fire is not suppressed (S50), the first control unit 40 transmits this state to the second control unit 20 The second control unit 20 controls the global fire fighting equipment 50 to operate according to the signal detected by the first sensing unit S60. As described above, the first control unit 40 and the second control unit 20 are interlocked and executed automatically in real time.

Accordingly, the global fire fighting equipment 50 discharges the inner gas into the EMDG chamber 200 and the EMDG room 300 through the inner supply pipe 51.

If the fire detection in the EMDG chamber 200 is completed in step S50 and the first sensing unit does not detect the fire condition, the fire suppression is terminated.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

By using the integrated fire fighting management system and method of the ship according to the present invention, the fire fighting management of the ship can be unified by integrally controlling the local fire fighting equipment and the global fire fighting equipment.
