As shown in Figures 1 to 4, the building disaster notification system 100 according to an embodiment of the present invention comprises a notification unit 110, the communication unit 120, the gateway unit 130 and the control unit 140 Include.

The alarm unit 110 generates a danger signal by sensing the inside of the building, and generates dangerous information when it is determined that the inside of the building is a dangerous situation, and is installed inside the building.

The notification unit 110 may be provided in plural numbers and may be installed for each floor of a building, and generate a warning notification when danger information is generated.

The notification unit 110 may further include a sensor unit 111, a calculation unit 112, and an output unit 113.

The sensor unit 111 is installed inside the building to generate a danger signal by sensing the inside of the building.

The sensor unit 111 may include a vibration sensor 111a, a temperature sensor 111b, a smoke sensor 111c, and a UV sensor 111d.

The vibration sensor 111a detects a vibration, and generates a danger signal when a vibration outside the specified vibration reference value is sensed. The danger signal generated by the vibration detection sensor 111a is transmitted to the calculation unit 112 described later. do.

For example, the vibration sensor 111a detects vibration and generates a dangerous signal when a disaster such as an earthquake occurs, and the generated dangerous signal may be transmitted to the calculator 112.

Meanwhile, the vibration sensor 111a may detect small vibrations generated by a rolling phenomenon before a large earthquake occurs. When small vibrations are periodically generated, the vibration sensor 111a generates a dangerous signal. It may be transferred to the operation unit 112.

According to this, since a dangerous signal can be transmitted to the calculating unit 112 before a large earthquake occurs, damage can be prevented.

On the other hand, since the vibration caused by the earthquake is stronger as the number of floors higher than the low floor, the vibration sensor 111a may be selectively attached only to the lower floors such as the first to fourth floors.

The temperature sensor 111b senses the ambient temperature, and generates a dangerous signal when the specified temperature reference value is exceeded. The dangerous signal generated by the temperature sensor 111b is transmitted to the operation unit 112.

For example, the temperature sensor 111b may generate a danger signal by detecting a temperature inside the building that increases when a fire occurs in the building.

On the other hand, the temperature sensor 111b is interlocked with the sprinkler in the building, when the danger signal can be caused to operate the sprinkler.

As the smoke detection sensor 111c detects smoke, a danger signal may be generated when the specified smoke threshold is exceeded.

For example, when a fire occurs in a building, a danger signal may be generated by detecting smoke caused by the fire.

The smoke detection sensor 111c is interlocked with the ventilator inside the building, and when the danger signal is generated, the ventilator may be operated.

In addition, the smoke detection sensor 111c is interlocked with the lock installed in the door and the door of the building, when the danger signal is generated, the lock installed in the door can be released and the door can be opened.

The UV detection sensor 111d detects UV (Ultraviolet Ray) generated from the flame, and generates a danger signal when the UV generated by the flame is detected in the building.

The UV wavelength generated by the flame is 185 nm to 260 nm, and the UV detection sensor 111d may generate a danger signal when detecting UV in the 185 nm to 260 mm wavelength band.

On the other hand, the sensor unit 111 is preferably installed on the ceiling inside the building for effective sensing, because smoke, heat, etc. generated during a fire is moved to the ceiling inside the building.

The sensor is not limited to the above-described vibration sensor 111a, the temperature sensor 111b, the smoke sensor 111c, the UV sensor 111d, and the building such as a leak detection sensor and a Co2 detection sensor. Any sensor may be used as long as it can detect a factor causing a dangerous situation within the sensor.

The calculating unit 112 generates dangerous information, and receives a dangerous signal from the sensor unit 111. The calculating unit 112 analyzes the received dangerous signal and generates dangerous information when it is determined that the inside of the building is a dangerous situation.

Evacuate the hazard information outside by using the location where the danger signal occurred (e.g. floors), the type of disaster (e.g. fire), and the emergency response situation (e.g. an office fire not available north of the elevator. ) May be included.

The output unit 113 is a warning notification for informing the danger is generated, it is electrically connected to the operation unit 112 to operate when received the risk information from the operation unit 112.

The output unit 113 includes a light emitting unit 113a, a speaker unit 113b, and a vibration unit 113c in more detail.

The light emitting unit 113a generates warning light when dangerous information is received, and is electrically connected to the calculating unit 112.

For example, the light emitting unit 113a may be provided as a siren to generate red light when the dangerous information is received from the calculating unit 112.

According to the light emitting unit 113a, it is possible to effectively notify that a dangerous situation has occurred, so that people inside the building can quickly evacuate out of the building.

The speaker unit 113b generates a warning sound when dangerous information is transmitted, and is electrically connected to the operation unit 112.

Here, the warning sound may be provided in various types such as a siren and a human voice.

These alerts can effectively signal that a dangerous situation has occurred, so that people inside the building can evacuate quickly.

The vibrator 113c generates vibration when dangerous information is transmitted, and is electrically connected to the operation unit 112.

The vibrator 113c may be provided to vary the intensity of the vibration step by step.

For example, when the dangerous information is first generated, a weak vibration is generated, and when the dangerous information is continuously transmitted, the intensity of the vibration may increase.

Meanwhile, a display (not shown) may be installed in the output unit 113.

Accordingly, when the risk information is transmitted to the output unit 113, the risk information may be displayed on the display.

For example, if smoke is detected in a three-story building, the display (not shown) may display textual information such as "Smoke was detected on the third floor" or "Escape using the three-story fire emergency north stairs." Can be.

In addition, the output unit 113 may be provided with lighting, according to the illumination can be provided to the evacuation direction according to the risk information to the user.

For example, the illumination may be provided so that the arrow-shaped light is irradiated.

Through such illumination, the arrow-shaped light is irradiated to the floor of the building so that the evacuation direction can be quickly provided to the user.

The communication unit 120 transmits danger information to the outside and is installed in the notification unit 110.

For example, although not shown in the drawing, the communication unit 120 may be provided in a thin plate shape, and the notification unit 110 may be formed with a thin groove corresponding to the shape of the communication unit 120.

According to both of these configurations, the above-described communication unit 120 may be inserted into the thin groove formed in the notification unit 110 in a slot manner.

In addition, the notification unit 110 may be provided with a discharge button so that the incoming communication unit 120 can be easily discharged from the groove.

When the user presses the above-described discharge button, the communication unit 120 may be discharged to the outside of the notification unit 110 again.

According to the structure of both configurations, since the communication unit 120 can be completely drawn into the inside of the notification unit 110, the installation space can be saved, there is an effect that the installation and removal of the communication unit 120 is easy.

The communication unit 120 may transmit risk information to the outside using a long range (LoRa) communication method.

Here, LoRa means a low-power long-distance communication technology that allows objects to communicate with each other.

Compared with other communication technologies, this LoRa method can communicate over long distances with less power, and has the advantage of low initial infrastructure construction cost and high scalability.

In addition, when communicating in the LoRa method, there is an advantage that the battery life can be maintained for a long time because the power consumption is low.

Since the communication unit 120 transmits the risk information to the outside using the LoRa method, the communication unit 120 consumes less power and lowers maintenance cost than other communication methods.

In more detail, when the communication unit 120 uses a conventional communication method other than the LoRa method, a communication modem should be installed in each of the notification units 110 in the building in order to transmit danger information to the outside.

For example, when all the notification units 110 are installed on each floor of a ten-story building, the communication modem should be provided in ten so as to correspond to the number of installation of the notification unit 110.

Each of the above-described communication modems generates a communication fee. Therefore, as the number of communication modems increases, the operating cost of the system increases.

However, when using the LoRa method, since the plurality of communication units 120 are transmitted to the outside through a single modem through the gateway unit 130 to be described later, the communication fee can be significantly reduced.

In addition, since the LoRa method consumes less power because of less power consumption, the LoRa method has an effect that the maintenance cost of the system can be greatly reduced.

The gateway unit 130 receives the dangerous information and converts it into data, and is installed inside the building and electrically connected to the communication unit 120.

The above-described gateway unit 130 may be provided as a functional unit or device that allows two or more different types or the same types of communication networks to be interconnected to exchange information between communication networks.

When the gateway unit 130 receives risk information from the communication unit 120, the gateway unit 130 converts each risk information into data and transmits the dangerous information to the control unit 140 to be described later.

The control unit 140 transmits dangerous information to the terminal t inside the building, and is electrically connected to the gateway unit 130.

For example, the control unit 140 may notify the risk information in the building by transmitting the risk information data generated by the gateway unit 130 to a PC, a mobile device, etc. existing in the building.

On the other hand, when the control unit 140 receives the risk information, by transmitting the risk information to the fire station, rescue facilities, etc., the firefighter or emergency rescue personnel can be dispatched to the building where the dangerous situation occurred.

According to the control unit 140, there is a section that people can quickly evacuate to the outside of the building because it can effectively inform the people in the building a dangerous situation occurred in the building.

According to the building disaster notification system 100 including the notification unit 110, the communication unit 120, the gateway unit 130, and the control unit 140 described above, the building with low power and reasonable maintenance cost using the LoRa method. It can effectively communicate the disaster situation within.
