Japanese Unexamined Patent Publication No. 2005-316533

However, in the technique described in Patent Document 1, since a plurality of sensors are arranged at a plurality of locations, the space occupied by the plurality of sensors becomes large. On the other hand, in ships and the like where the internal space is limited, there has been a demand to keep the space occupied by a plurality of sensors small.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a ship capable of keeping the space occupied by a plurality of sensors small.

In order to solve the above problems, the present invention employs the following means.
That is, the ship according to one aspect of the present invention is provided on a watertight compartment, a sensor device attached to the ceiling of the watertight compartment, and a floor portion located below the ceiling of the watertight compartment, and is provided with a flood detection sensor.

A control unit that controls a sensor, an interface provided on the housing and connectable to the external sensor, an internal sensor housed in the housing, and an external sensor connected to the interface. And an internal functional element including the internal sensor, the control unit, and an internal power supply that supplies power to the external sensor while being housed in the housing.

According to this configuration, since a plurality of internal sensors are housed in the housing of the sensor device, the housing of each sensor can be shared, and the plurality of sensors are individually arranged at a plurality of locations. Compared with the configuration, the plurality of sensors as a whole can have a compact configuration. As a result, the space occupied by the plurality of sensors can be kept small while being provided.
Further, as an internal functional element used together with the internal sensor, for example, an evacuation guidance element such as an LED light or a speaker is housed in the housing to reliably perform evacuation guidance in the event of a disaster. it can. As a result, it is possible to add other functions to the sensor device, such as improving safety by shortening the evacuation time of personnel in the event of a disaster.
Further, since the internal power supply is housed in the housing, even if the power supply is cut off due to the occurrence of a disaster, the sensor device can be operated by the power from the internal power supply.
Further, for example, when a smoke sensor is provided as an internal sensor and a sensor for detecting gas or inundation having a specific gravity larger than that of air is provided as an external sensor, each sensor can be arranged at a position according to the characteristics. The sensor can function smoothly.

Further, in the sensor device, at least one of the internal sensor and the external sensor detects the internal functional element in the housing, and the detected value information acquired by the control unit is wirelessly transmitted to the outside. A wireless communication unit for transmission may be accommodated.

According to this configuration, since the wireless communication unit is housed in the housing, even if the wired communication with the outside is cut off due to the occurrence of a disaster, the wireless communication unit is used to control the control unit. The detected value information acquired by can be transmitted to the outside.

Further, the sensor device includes a fixing member for fixing the housing to a mounting portion to which the housing is mounted, and the fixing member is connected to the housing or the mounting portion via an elastic member. May be good.

According to this configuration, since the housing or mounting portion and the fixing member are connected via the elastic member, an impact is applied to the mounting portion of the housing due to a disaster or the operation of a ship. Even so, the elastic member can cushion this impact. Therefore, the impact resistance performance of the sensor device can be improved while using a general-purpose general-purpose sensor as the internal sensor in the housing. As a result, it is not necessary for the internal sensor itself to have a specification having impact resistance, and the cost of the sensor device can be reduced.
