    摘要: A fire suppression system according to an embodiment of the present invention comprises: a detection unit for detecting a particular change due to a fire and transmitting a particular change value as a measurement value; a fire extinguishing unit for spraying a fire extinguishing substance; a control unit for receiving the measurement signal and transmitting an execution signal to the fire extinguishing unit; and a management unit enabling a user or a manager to confirm whether or not there is a fire, and for remotely operating the fire extinguishing unit, wherein the control unit transmits a notification signal to the management unit only when a measured measurement data value exceeds a threshold value, and transmits the execution signal only when an operation command is received from the management unit, thereby enhancing convenience and safety and reducing the initial cost.

    摘要: The system and device for rapid communication with emergency responders during a crisis includes a wearable alarm and notification device. The wearable device is worn by, for example, the staff and faculty members of a school. When activated, the wearable device sends a signal to a central system or server, the central system simultaneously triggering numerous actions. For example, the server simultaneously performs the following actions: sending alerts to parties based on predefined groups; causing the public address system to play an alarm or a prerecorded message; sending messages by additional other means, for example SMS, email, phone calls, push notifications, and so forth; and triggering a lockdown, the lockdown either of the area around the activated mobile device, the entire campus, or a subset of the entire campus.

    摘要: According to various embodiments of the present invention, an individual's dangerous state detection-based situation information acquisition device may include: a sensor unit configured to detect an individual's state; a control unit configured to determine that the individual's state is a dangerous state when the rate of change of the maximum value of a sensor data stream detected by the sensor unit satisfies Equation 1 below; a camera configured to photograph the surroundings of the situation information acquisition device from the time when it is determined that the individual's state is a dangerous state; and a voice recorder configured to record sounds generated in the surroundings. Other embodiments may also be possible.
