The external memory may be functionally and / or physically connected to the electronic device through various interfaces.

The storage unit 120 according to an embodiment of the present invention may store information related to the fire extinguisher serial number. According to various embodiments of the present disclosure, the IoT fire extinguisher pedestal 100 corresponds to a fire extinguisher serial number (or IoT fire extinguisher pedestal serial number) previously stored in the storage 120 to inform the user of transmitting a signal when transmitting a signal to the user device 300 or the server 200. Information can be sent together. For example, when a fire occurrence is detected and a fire detection signal is transmitted from the IoT fire extinguisher base to the server 200, the fire extinguisher serial number is transmitted together with the server 200 so that the location of the fire can be identified through the serial number. It works.

In addition, the storage unit 120 may store instructions related to operations performed in the IoT fire extinguisher stand.

For example, the sensor unit 130 may measure a physical quantity or detect an operation state of the electronic device to convert the measured or detected information into an electrical signal.

The weight sensor is installed at the bottom of the center of the IoT fire extinguisher cradle, and may be designed to detect the weight of the fire extinguisher as the fire extinguisher is mounted. The fire extinguisher needs to be shaken periodically to prevent sticking. Accordingly, when the change in the weight of the fire extinguisher is not detected for more than a predetermined period, the weight sensor may be determined that the inspection activity such as shaking the fire extinguisher is not performed. If the weight sensor does not detect a change in weight for more than a predetermined period, the IoT fire extinguisher pedestal (control unit) may transmit a check request signal to the server 200 or the peripheral user device 300 through a communication unit. According to various embodiments of the present disclosure, if it is determined that the fire extinguisher check is not performed for more than a preset time (when the weight is not detected for a predetermined period or more), a method of illuminating a light emitting unit (different from the fire extinguisher position notification method) Can be set, for example, a blinking light).

In addition, the weight sensor of the sensor unit 130 may sense whether the fire extinguisher is mounted on the IoT fire extinguisher base. Accordingly, the IoT fire extinguisher pedestal may transmit a notification to the administrator device or the server that indicates the termination of the extinguisher when the state in which the fire extinguisher is not maintained lasts more than a preset period (for example, 1 day). This allows the server to get a complete picture of where the fire extinguisher is currently not equipped.

For example, the beacon generation controller 161 may control to transmit a beacon signal having a different value according to the scale of the fire. In addition, when the beacon generation control unit 161 needs to inform the location of the fire extinguisher according to the beacon transmission situation, the beacon generation control unit 161 may include information corresponding to the fire extinguisher serial number in the beacon signal and transmit it.

The fire extinguisher check request unit 162 may check whether the fire extinguisher is checked by detecting a change of the fire extinguisher mounted state generated when the fire extinguisher is checked. Specifically, the fire extinguisher check request unit 162 may determine that the fire extinguisher check is not made when the weight sensor does not detect a change in the weight of the fire extinguisher for more than a preset period, and may perform an operation for requesting the fire extinguisher check. In this case, the operation for requesting the fire extinguisher check may include a method of transmitting a signal and a method of operating itself. First, the method of transmitting a signal may include a method of transmitting a beacon signal to the user device 300 existing within a preset distance range so that the user can check a message corresponding to the beacon signal through the user device 300 kHz. The self-operating method may correspond to, for example, output of a notification sound or emission of a light emitting body for notifying an administrator or a neighboring user of the arrival of a fire extinguisher check time.

According to an embodiment of the present disclosure, the peripheral user device 300 may roughly determine the location of the fire extinguisher based on the strength of the received beacon signal.

In addition, the control unit 160 may perform an operation to assist the evacuation of the user according to the level of fire. As the risk of fire increases, an operation of finding an escape route may be given priority over an operation of searching for a fire extinguisher, so that the controller 160 transmits and receives information on the size of the fire from the server 200 in real time and correspondingly stored in the server 300 instead of the location of the fire extinguisher. It is possible to support the user device 300 to receive the evacuation route information of the building (for example, to transmit a beacon signal to the user device 300 to request the evacuation information from the server).

The server 200 may extract feature information (eg, evacuation route map information) of the building where the user is located based on the information.

The beacon signal analyzer 372 may analyze the signal strength of the beacon signal received from the IoT fire extinguisher pedestal 100. Accordingly, the user device 300 may determine that the closer the IoT fire extinguisher pedestal 100 is, the greater the intensity value of the received beacon signal is. Accordingly, the user can search for the location of the fire extinguisher while moving in a large direction of the beacon signal measured by the user device 300, and can easily find a fire extinguisher that does not exist within the visible distance.

The rescue location notification unit 373 may determine whether a user of the user device 300 is a rescue target according to an embodiment of the present disclosure. The structure location notification unit 373 may determine whether the user is in possession of the user based on the movement of the user device 300 detected by the sensor 360.

If not, it can be determined that the user does not possess it. When the movement of the user device is not detected for more than a preset time, the rescue location notification unit 373 may transmit a signal for registering the user device 300 to the server 200 as an unresponsive device. Accordingly, since the user device is not in possession of the user in the server 200, the location information of the user device may be excluded from the data for identifying the location of the rescued person.

In addition, the rescue position notification unit 373 may determine the stage information of the fire. The rescue location notification unit 373 may determine the fire size and stage information based on the fire notification signal received from the IoT fire extinguisher pedestal 100 or the server 200, and if it is determined that the detected fire event is at a level higher than a preset risk level. The information on the current location of the user may be controlled to be transmitted to the server 200 in real time.
