Emergency and exigency situation notification system

An emergency and exigency situation notification system, the system comprising a control unit configured to determine emergency and exigency situations, wherein the control unit is connected to a reception unit and an alarm drive unit and refers to a database (DB);

• wherein the reception unit receives sounds, including human voices and environmental sounds of objects other than humans, which are collected in a surrounding environment;
• wherein the control unit includes an emergency situation control unit configured to determine that a situation in question is an emergency situation when an abnormality occurs in the environmental sound data other than human voices collected by the reception unit, an exigency situation control unit configured to determine that a situation in question is an exigency situation when a specific term indicative of danger is included in the voices, and a data control unit configured to secure and update data stored in the DB;
• and
• wherein the emergency situation control unit, when the environmental sound data received by the reception unit is included in stability data learned in advance and stored, determines that a situation in question is in a calm state and decreases an emergency situation data index, and, when the environmental sound data received by the reception unit is not included in stability data learned in advance and stored, increases the emergency situation data index and transmits an alarm signal to an alarm drive unit when a final value of the emergency situation data index reaches a predetermined maximum emergency situation index value.
