Abstract

An evacuation guidance system includes: an evacuation guidance management system that acquires information of a disaster which has occurred in a marine vessel, acquires passenger position information in the marine vessel, formulates an evacuation route, and specifies a passenger to be subjected to evacuation guidance and a position of the passenger; and a mobile body that performs control to move an own device to the position of the specified passenger on the basis of the specified passenger and the position of the passenger and to move the own device along the evacuation route while outputting guidance information to the passenger.

Claims (39)

1 . An evacuation guidance system comprising:

a management system including

a disaster information acquisition unit configured to acquire information of a disaster which has occurred in a marine vessel,

a personnel distribution information acquisition unit configured to acquire position information of passengers in the marine vessel on the basis of information of a sensor which detects a person,

a route calculation unit configured to formulate an evacuation route on the basis of passage passability information which is set from the position information of the passengers from the personnel distribution information acquisition unit and the information of the disaster, and

a guidance target passenger specification unit configured to specify a passenger to be subjected to evacuation guidance and a position of the passenger from the position information of the passengers acquired by the personnel distribution information acquisition unit and the information of the disaster; and

a mobile body including:

a control unit configured to move an own device to the position of the passenger specified by the guidance target passenger specification unit on the basis of the specified passenger and the position of the specified passenger and to move the own device along the evacuation route calculated by the route calculation unit to guide the passenger when the own device is moved to the position of the passenger, and

an input unit configured to receive input of information in a contact manner and an output unit,

wherein the output unit outputs information requesting input of predetermined information in the contact manner through the input unit when a position of the own device is within a predetermined range from the position of the passenger, and

when the predetermined information is input from the input unit, the control unit determines that the own device has been moved to the position of the passenger.

2 . The evacuation guidance system according to claim 1 ,

wherein the mobile body includes an input unit configured to receive input of information in a non-contact manner, and

when predetermined information is input from the input unit in the non-contact manner, the control unit determines that the own device has been moved to the position of the passenger.

3 . The evacuation guidance system according to claim 2 ,

wherein the non-contact input is an input of voice information uttered by the passenger or an input by a gesture of the passenger.

4 . The evacuation guidance system according to claim 1 ,

wherein the control unit moves while monitoring a positional relationship between the passenger and the own device and adjusts a movement speed such that the position of the passenger is maintained within a predetermined range from the own device.

5 . The evacuation guidance system according to claim 4 ,

wherein, when the position of the passenger deviates from the range, the control unit moves in a reverse direction on the evacuation route to search for the passenger, on the basis of the position information of the passenger.

6 . The evacuation guidance system according to claim 1 ,

wherein the control unit moves while monitoring a positional relationship between the passenger and the own device and issues an alarm when the position of the passenger deviates from a predetermined range.

7 . The evacuation guidance system according to claim 1 , further comprising:

a mobile terminal configured to be possessed by the passenger and to measure position information of the mobile terminal,

wherein the control unit moves the own device to the position of the passenger by moving the own device on the basis of position information of the mobile body and the position information of the mobile terminal possessed by the specified passenger such that the position information of the mobile body approaches the position information of the mobile terminal.

8 . The evacuation guidance system according to claim 1 , further comprising:

a monitoring terminal configured to be provided on land,

wherein the management system is provided in the marine vessel,

the monitoring terminal transmits information of a movement route of the mobile body to the management system,

the management system acquires the information of the movement route, and

the control unit moves the own device on the basis of the information of the movement route acquired by the management system.

9 . An evacuation guidance method executed by an evacuation guidance system that performs evacuation guidance for passengers using a mobile body, the evacuation guidance method comprising:

a step of acquiring information of a disaster which has occurred in a marine vessel;

a step of acquiring position information of the passengers in the marine vessel on the basis of information of a sensor which detects a person;

a step of formulating an evacuation route on the basis of passage passability information which is set from the position information of the passengers and the information of the disaster;

a step of specifying the passenger to be subjected to the evacuation guidance and a position of the passenger from the position information of the passengers and the information of the disaster;

a step of moving the mobile body to the position of the specified passenger on the basis of the specified passenger and the position of the specified passenger; and

a step of, when an own device is moved to the position of the specified passenger, moving the mobile body along the evacuation route to guide the passenger,

wherein, in the step of moving the mobile body and guiding the passenger, outputting through an output unit of the own device information requesting input of predetermined information in the contact manner through an input unit of the own device when a position of the own device is within a predetermined range from the position of the passenger, and determining that the own device has been moved to the position of the passenger when the predetermined information is input from the input unit.
