Urban Air Mobility (UAM) is a three-dimensional urban air transportation system that connects the ground and air, and is a next-generation transportation system that can supplement or replace the existing ground transportation system provided in the city center.

On the other hand, urban air mobility, that is, a small aircraft may have an abnormality during flight. For example, an abnormality may occur in the rotation of a rotor of an aircraft or an abnormality in which an attitude is not adjusted to a target angle may occur. If the aircraft continues to fly in a state where such an error occurs, an accident in which the aircraft crashes or collides with another obstacle may occur.

Therefore, when an abnormality occurs in the aircraft, it is necessary to make an emergency landing of the aircraft according to the degree of the abnormality. That is, it is necessary to urgently make an emergency landing of an aircraft before reaching its destination.

However, since the emergency landing of an aircraft is an unexpected emergency situation, there may be people in or around the emergency landing site of the aircraft. Therefore, human casualties may occur during an emergency landing of an aircraft. Therefore, when it is determined that the emergency landing of the aircraft is necessary, it is necessary to generate a notification or warning notifying the emergency landing of the aircraft.

The driving control unit is a means for controlling the operation of the flight driving unit so that the aircraft 100 can take off from the ground to the air, land from the air to the ground, or move in the air. The driving control unit may receive a signal from the controller 200 and use it to control the operation of the flight driving unit 120 . For example, the controller 200 may transmit a take-off or landing signal to the driving control unit. In this case, the driving control unit controls the operation of the flight driving unit 120 so that the vehicle 100 can take off or land. In addition, a path (flight path) for flying the vehicle may be set or stored in advance in the controller 200, and the controller 200 transmits a signal including the preset flight path to the driving control unit. Then, the driving control unit controls the operation of the flight driving unit 120 so that the vehicle 100 can move or fly along the flight path transmitted from the controller 200.

The sensor is a means for detecting a state of the flight drive unit 120 mounted on the flight drive unit 120 . The sensor may be provided in plurality, and may be connected to or mounted to components constituting the flight drive unit 120 .

For example, the sensor is installed on at least one of the first to fourth rotor sensors connected to the first to fourth rotors 124a to 124d, the main body 110, and the first to fourth wings 121a to 121d, and At least one of the posture sensors for detecting the posture of (100) may be included.

Here, each of the first to fourth rotors 124a to 124d may include a motor providing rotational power and a plurality of blades connected to the motor, and the rotor sensor is connected to the motor to sense or detect the number of revolutions of the motor. It can be arranged to detect. The number of rotations of each of the first to fourth rotors 121a to 121d detected by the first to fourth rotor sensors may be transmitted to the emergency landing determining unit 131 of the emergency landing notification device 130 to be described later. Also, the emergency landing determining unit 131 determines whether an emergency landing is required using the number of revolutions transmitted from each of the first to fourth rotor sensors.

Also, the attitude sensor may be a means including a gyro sensor. Here, the gyro sensor may be a sensor that measures angular velocity. The angular velocity measured by the gyro sensor is transmitted to the emergency landing determination unit 131, which will be described later, and the emergency landing determination unit 131 determines whether an emergency landing is necessary using the angular velocity transmitted from the gyro sensor.

The position detector is a means for detecting the height and horizontal position of the aircraft 100 . This position detector may include a first detector for detecting the altitude of the vehicle 100 and a second detector for detecting the position in the horizontal direction. Here, the first sensor may be means including, for example, a pitot tube through which fluid (liquid or gas) flows. The first sensor may sense or detect the altitude of the air vehicle 100 by using a change in pressure inside the pitot tube according to altitude. Also, the second sensor may be a means comprising, for example, a global positioning system (GPS). The height of the vehicle 100 sensed by the first detector and the position in the horizontal direction sensed by the second detector may be transmitted in real time to the emergency landing notification device 130 and the controller 200 installed on the ground.

In the above, it has been described that the first sensor includes a pitot tube and the second sensor includes a GPS. However, if the first detector can detect the altitude of the aircraft 100, any means may be used, and if the second detector can detect the horizontal position of the aircraft 100, any means may be used.

Hereinafter, the emergency landing notification device 130 according to an embodiment of the present invention will be described with reference to FIG. 2 . At this time, the operation is controlled by the emergency landing notification device 300, and the notification generator generating a notification informing of the emergency landing of the aircraft 100 generates a terminal 400 capable of receiving a message and an emergency sound. The emergency dispatcher 500 that can be described as an example.

Referring to FIG. 2, the emergency landing notification device 130 includes an emergency landing determination unit 131 that determines whether an emergency landing of the vehicle 100 is necessary using a signal or data transmitted from a sensor, and When it is determined that an emergency landing is required, it may include a landing location determination unit 132 for determining any one of a plurality of previously set or stored landing locations as a landing location.

In addition, the emergency landing notification unit 130 includes a message generating unit 133 that generates an emergency landing notification message including information on the determined landing location, and communication to be used to transmit the emergency landing notification message according to the determined landing location. It includes a communication base station selector 134 that selects a base station 300 and a message transmitter 135 that transmits an emergency landing notification message generated using the selected communication base station 300 to the terminal 400, which is a notification generator. can

In addition, the emergency landing notification device 130 includes an emergency dispatcher selection unit 136 that selects an emergency dispatcher 500, which is a notification generator capable of generating an emergency announcement sound, and an emergency announcement sound with the selected emergency dispatcher 500. It may include an emergency sound generation control unit 137 that transmits a signal to generate. Here, the emergency dispatcher selector 136 selects at least one of a plurality of emergency dispatchers according to the determined landing position.

The emergency landing determination unit 131 detects whether an abnormality has occurred in the aircraft 100 using signals or data transmitted from at least one of a plurality of sensors. For example, the emergency landing determination unit determines whether an emergency landing is necessary using the number of revolutions of the first to fourth rotors (hereinafter, hereinafter referred to as first to fourth rotational speeds) detected by the first to fourth rotor sensors. In other words, the emergency landing determination unit 131 determines whether or not to make an emergency landing of the vehicle 100.

More specifically, the emergency landing determining unit 131 may make the determination using the difference between the number of revolutions detected by the first to fourth rotor sensors and the difference in the preset reference number of revolutions. At this time, the reference rotation speed difference is a larger value than the first reference rotation speed difference and the first reference rotation speed difference, which are the rotation speed difference for determining whether or not an abnormality has occurred in the first to fourth rotors 121a to 121d, and whether an emergency landing is required. It may include a second reference rotation speed difference that is a rotation speed difference that determines .

In addition, the emergency landing determination unit 131 determines that there is no problem with the vehicle 100 when the difference between the first to fourth rotation speeds is less than or equal to the first reference rotation speed difference. However, when the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference, the emergency landing determination unit 131 determines that there is something wrong with the vehicle 100. At this time, if the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference and is less than the second reference rotation speed difference, the emergency landing determination unit 131 determines that an abnormality has occurred in the vehicle 100, but an emergency landing is required. decide not to However, when the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference and exceeds the second reference rotation speed difference, the emergency landing determining unit 131 determines that an emergency landing is required.

As another example, the emergency landing determination unit 131 determines whether it is necessary to make an emergency landing of the aircraft 100 using a signal detected by a posture sensor, for example, a gyro sensor.

The gyro sensor may be a means for detecting or measuring the angular velocity of the vehicle 100 . The angular velocity detected by the gyro sensor may be transmitted to the emergency landing determining unit 131 . The emergency landing determination unit 131 may calculate the angle of the aircraft through an operation using the angular velocity transmitted from the gyro sensor, for example, through an integral operation.

Hereinafter, for convenience of description, the angle of the aircraft calculated using the angular velocity detected by the gyro sensor is referred to as 'the detected angle of the aircraft'.

The emergency landing determination unit 131 may determine whether an abnormality of the aircraft 100 has occurred and whether an emergency landing is required by using the difference between the detected angle of the aircraft 100 and the target angle. Here, the target angle may be an angle determined according to movement of the aircraft, change in direction of movement, change in altitude, and the like. And when the target angle is determined, it is transmitted to the driving control unit, and the driving control unit operates the flight driving unit 120 to reach the target angle.

As described above, the emergency landing determining unit 131 determines the difference between the detected angle of the vehicle 100 and the target angle and the difference between the preset reference angle. At this time, the reference angle difference is a larger value than the first reference angle difference and the first reference angle difference used to determine whether an abnormality of the aircraft 100 has occurred, and the second used to determine whether an emergency landing of the aircraft 100 is necessary. A reference angle difference may be included.

Then, the emergency landing determination unit 131 determines that there is no problem with the vehicle 100 when the difference between the angle of the vehicle detected and the target angle is equal to or less than the first reference angle difference. However, when the angle difference exceeds the first reference angle, the emergency landing determination unit 131 determines that there is something wrong with the vehicle 100. At this time, if the difference between the detected angle of the aircraft and the target angle exceeds the first reference angle difference and is less than the second reference angle difference, the emergency landing determination unit 131 determines that an error has occurred in the aircraft 100, but an emergency landing is required. decide not to However, when the angle difference exceeds the first reference angle difference and the second reference angle difference, the emergency landing determining unit 131 determines that an emergency landing is required.

Figure 3 is an example showing a form in which a plurality of landing sites and the location of each landing site are stored in the landing location determination unit according to an embodiment of the present invention.

The landing location determination unit 132 determines the emergency landing location of the vehicle 100, that is, the landing site. That is, when it is determined that the emergency landing of the vehicle 100 is necessary in the emergency landing determination unit 131, the landing location determination unit 132 determines the landing site to land the aircraft 100. To this end, the landing location determination unit 132 may land the vehicle 100, and the locations of a plurality of landing sites at different locations are stored. And the landing location determination unit 132 determines the landing site located closest to the current position of the aircraft 100 among the plurality of stored landing sites as the landing site to land the aircraft 100.

Each of the plurality of landing pads stored in the landing location determining unit 132 may mean a place, zone, area or space having an area in which the vehicle 100 can be landed. Also, the locations of the plurality of landing sites are different. Accordingly, the landing location determination unit 132 may store a plurality of landing sites and location information for each of them in association or matching (matching). That is, n landing sites and location information for each landing site may be stored in the landing location determining unit 132 . Referring to FIG. 3 as an example, the landing position determination unit 132 includes a position for the first landing site (first landing position), a position for the second landing site (second landing position), ... , the location for the n-1 landing site (n-1 landing location), and the location for the n-th landing site (n-th landing location) may be stored.

A plurality of such landing sites may be places determined in advance by agreement or agreement. For example, a plurality of landing sites may be places where emergency landing is allowed or permitted by the national or local government for the operation of urban air mobility. In other words, a plurality of landing sites where an emergency landing of the aircraft 100 is allowed is agreed or agreed in advance, and the positions of the plurality of landing sites promised in this way are stored in the landing location determining unit 132 . In addition, it is preferable that the plurality of landing pads are located at positions that can minimize damage to human life or damage to structures such as surrounding buildings during landing. For example, the plurality of landing locations may be a field, a plaza, a plain, a rooftop of a building, and the like. In addition, a plurality of landing sites determined by regulations may be provided for each country and a plurality for each region.

The landing location determination unit 132 determines one of a plurality of landing sites according to the current position of the aircraft 100 as a landing site for emergency landing of the aircraft. That is, the landing site located closest to the aircraft 100 among the plurality of landing sites stored in the landing location determination unit 132 is determined or selected as a landing site for emergency landing of the aircraft. More specifically, a landing field located closest to the position of the aircraft 100 detected by the position detection unit of the aircraft at or immediately after the emergency landing determination unit 131 determines that the aircraft 100 needs an emergency landing. is determined as a landing field to land the vehicle 100. In other words, the landing position determining unit 132 calculates the distance for the aircraft 100 to move from the current position to each of the plurality of landing sites, and the calculated movement distance is the closest landing site to land the aircraft 100. Determine the landing site. The landing site located closest to the aircraft 100 among the plurality of landing sites can be determined as the landing site because the landing location determining unit 132 stores the locations of each of the plurality of landing sites.

The message generating unit 133 generates an emergency landing notice message to be transmitted to the terminal 400 . At this time, the message generating unit 133 may generate a message with content including, for example, an address of the location of the landing site where the vehicle 100 is to land. To this end, the message generation unit 133 may generate a message after the landing location determining unit 132 determines the location where the vehicle 100 is to be landed. In this way, when a message is generated and transmitted to include the location of the landing field where the aircraft 100 will land, people who receive the message through the terminal 400 can recognize the landing location of the aircraft 100 and prepare for it. That is, it is possible to evacuate by recognizing the landing position.

Also, when generating a message in the message generating unit 133, it is preferable to generate the message to include the name of the determined landing site. For example, if the name of the determined landing site is 'Plaza A', the message may be generated to include the name of 'Plaza A'. In this way, when a message is generated and transmitted to include the name of the landing site where the aircraft 100 will land, people who receive the message through the terminal 400 can more intuitively recognize the landing location of the aircraft 100.

In addition, the message generation unit 133 may predict the emergency landing time of the aircraft 100 and generate a message to include the predicted time. This can be predicted using at least one of the moving speed of the aircraft 100, the distance between the current position of the aircraft 100 and the determined emergency landing field, and the current time.

4 is an example showing a form in which a plurality of communication base stations and the location of each communication base station are stored in a communication base station selection unit according to an embodiment of the present invention.

The communication base station selection unit 134 selects the communication base station 300 to be used for transmitting the emergency landing notice message. At this time, the communication base station selection unit 134 selects the communication base station 300 to be used according to the location of the landing site determined by the landing location determining unit 132.

To this end, the communication base station selector 134 stores location information about a plurality of communication base stations 300 equipped with communication equipment capable of transmitting an emergency landing notification message. Then, the communication base station selector 134 selects a communication base station whose distance from the determined landing pad is less than a preset first reference distance among a plurality of stored communication base stations as the communication base station 300 to be used for message transmission.

The communication base station 300 may be a communication facility that connects a network and the terminal 400 for wireless communication service. That is, the communication base station 300 may be a communication device capable of transmitting or transmitting an emergency landing notification message to a terminal such as a mobile phone or a tablet personal computer (PC). As a more specific example, a plurality of communication base stations, for example, code division multiple access (CDMA). It may be a communication facility of any one of GSM (Global System for Mobile Communications), WCDMA (Wideband Code Division Multiple Access), and LTE (Long Term Evolution).

Telecommunication companies install a plurality of communication base stations in each region for smooth communication service, and the installation locations are different. In this embodiment, as a communication base station used to transmit a message informing of an emergency landing of the aircraft 100, a communication base station already installed by a communication company is used. In other words, at least some of the plurality of communication base stations installed in the communication company are used as communication facilities for transmitting the emergency landing notification message of the aircraft 100. At this time, the communication base station installed around each of the plurality of landing pads stored in the landing location determination unit 132 is used as a communication facility for sending messages.

To this end, the communication base station selector 134 stores location information about a plurality of communication base stations. More specifically, communication base stations installed at locations less than a predetermined distance from each of the plurality of landing pads are used as communication base stations to be used for transmitting the emergency landing notice message of the aircraft 100. Accordingly, the location of the communication base station installed within a predetermined distance (predetermined separation distance) from each of the plurality of landing pads is stored in the communication base station selection unit 134.

At this time, the communication base station selector 134 may store a plurality of communication base stations and location information for each of them in association or matching. That is, location information on n number of communication base stations may be stored in the communication base station selector 134 . Referring to FIG. 4 as an example, the communication base station selector 134 includes a location for the first communication base station (first installation location), a location for the second communication base station (second installation location), ... , the location for the n-1th communication base station (n-1th installation location), and the location for the n-th communication base station (nth installation location) may be stored.

On the other hand, it has been described that the positions of n landing pads are stored in the landing location determination unit 132 described above, and the positions of n communication base stations are stored in the communication base station selection unit 134. At this time, 'n', the number of landing pads stored in the landing location determination unit 132, and 'n', the number of communication base stations stored in the communication base station selection unit 134, may be the same or different.

The communication base station selection unit 134 selects the communication base station 300 to be used for message transmission using the location of the landing field determined by the landing location determination unit 132. That is, the communication base station selector 134 selects a communication base station located or installed at a distance less than the first reference distance from the determined landing site among a plurality of stored communication base stations. At this time, the communication base station 300 located at the distance from the determined landing site to the first reference distance or less may be one or a plurality. Accordingly, the number of communication base stations selected by the communication base station selector 134 may be one or a plurality.

In the above, it has been described that a communication base station installed by a communication company is used as the communication base station 300 used to transmit an emergency landing notice message. However, the communication base station used for transmitting the emergency landing notification message may be separately prepared for transmitting a message for informing the emergency landing of the vehicle 100. At this time, the communication base station is installed so as to be located below the first reference distance in each of the plurality of landing sites stored in the landing location determination unit 132. Then, the location of the installed communication base station is stored in the communication base station selection unit 134.

The message transmission unit 135 transmits the emergency landing notification message generated by the message generation unit 133 . At this time, the message transmission unit 135 transmits an emergency landing notification message using the selected communication base station. Accordingly, an emergency landing notification message is sent or transmitted to the terminal 400 connected with the communication signal to the selected communication base station. In other words, an emergency landing notification message is transmitted to a terminal within a predetermined distance from the selected communication base station 300 . Therefore, people around the landing site where the aircraft 100 will make an emergency landing may receive the emergency landing notification message received through the terminal 400 and evacuate in advance, for example, before the aircraft 100 lands.

5 is an example of a form in which a plurality of emergency dispatchers and the location of each emergency dispatcher are stored in an emergency dispatcher selector according to an embodiment of the present invention.

First, the emergency dispatcher 500 will be described. The emergency dispatcher 500 may be a device that outputs a notification sound or warning sound informing of an emergency landing of the aircraft 100 . For example, the emergency dispatcher 500 may be a terminal including a loudspeaker or a speaker that outputs a siren sound indicating an emergency landing of the aircraft 100 .

A plurality of emergency dispatchers 500 may be provided, and the plurality of emergency dispatchers 500 may be installed in different locations. As a more specific example, the emergency dispatcher 500 notifying the emergency landing of the aircraft 100 may be a universal warning siren terminal (hereinafter referred to as civil defense alarm) already installed in each region to prepare for civil defense situations. In other words, it can be used as an emergency dispatcher 500 for notifying the emergency landing of the vehicle 100 to the all-round alarm already installed in each region.

Here, the civil defense alarm used to notify the emergency landing of the aircraft 100 may be an alarm that is permitted to be used by the national or local government for the operation of urban air mobility. In other words, the civil defense alarm that can be used for emergency landing notification of the vehicle 100 may be one that has been promised or stipulated in advance.

In using at least some of the plurality of civil defense alarms already installed as an emergency dispatcher 500 that notifies the emergency landing of the aircraft 100, the civil defense alarms located at a predetermined distance or less from each of the plurality of landing sites are emergency dispatchers ( 500) is preferred. Accordingly, the position of the civil defense alarm installed at a position of a predetermined distance or less in each of the plurality of landing sites is stored in the emergency dispatcher selection unit 136. At this time, the emergency dispatcher selection unit 136 may store a plurality of emergency dispatchers 500 and location information on each of them in connection or matching. That is, location information on n emergency dispatchers may be stored in the emergency dispatcher selector 136 . Referring to FIG. 5 as an example, the emergency dispatcher selection unit 136 includes a position for the first emergency dispatcher (first installation position), a position for the second emergency dispatcher (second installation position), . . . , a location for the n-1th emergency dispatcher (n-1th installation location), and a location for the nth emergency dispatcher (nth installation location) may be stored.

On the other hand, the positions of n landing pads are stored in the landing position determination unit 132 described above, the positions of n communication base stations are stored in the communication base station selection unit 134, and the n emergency dispatcher selection unit stores n emergency locations. It has been described that the location of the dispatcher is stored. At this time, 'n', the number of landing pads stored in the landing position determination unit 132, 'n', the number of communication base stations stored in the communication base station selection unit 134, and emergency dispatch stored in the emergency dispatcher selection unit The number of groups, 'n', may be the same as or different from each other.

The emergency dispatcher selection unit 136 selects the emergency dispatcher 500 to be used by using the location of the landing site determined by the landing location determination unit 132. That is, the emergency dispatcher selection unit 136 selects the emergency dispatcher 500 located or installed at a distance less than the second reference distance from the determined landing site. At this time, one or a plurality of emergency dispatchers located at a distance from the determined landing site that is less than the second reference distance may be provided. Thus, the number of emergency dispatchers 500 selected by the emergency dispatcher selection unit 136 may be one or a plurality. Here, the second reference distance may be the same as the above-described first reference distance, or may be smaller or larger than the first reference distance.

The emergency sound generation control unit 137 controls the operation of the selected emergency dispatcher 500 so that an emergency sound notifying the emergency landing of the aircraft 100 is generated in the selected emergency dispatcher 500. At this time, the emergency sound generation control unit 137 may be connected to the selected emergency sound dispatcher 500 through wireless communication. For example, the emergency sound generation controller 137 and the emergency sound dispatcher 500 may be connected through satellite communication. In this case, each of the emergency sound generation control unit 137 and the emergency dispatcher 500 may be equipped with a device that can be connected to satellite communication.

As another example, the emergency sound generation controller 137 and the emergency dispatcher 500 may be connected through wireless communication using the communication base station 300 described above. In this case, the emergency sound generation control unit 137 transmits a signal to the selected emergency dispatcher 500 using the communication base station 300 selected by the communication base station selector 134 and makes an emergency call in the selected emergency dispatcher 500. It can be operated so that an announcement sound is generated.

As another example, for example, when the emergency landing notification device 130 is provided in the controller 200 installed on the ground, the emergency sound generation control unit 137 and the emergency dispatcher 500 communicate through wired communication, for example, LAN ( local area network).

When the emergency sound generation control unit 137 operates the selected emergency dispatcher 500, an emergency notification sound is generated from the selected emergency dispatcher 500. Here, the emergency notification sound may be, for example, a siren sound.

That an emergency notification sound is generated from the selected emergency dispatcher 500 means that an emergency notification sound is generated from an emergency dispatcher 500 installed around a landing field where an aircraft is to land or installed within a predetermined distance. Therefore, people around the landing site where the aircraft 100 will make an emergency landing can prepare in advance before landing the aircraft 100 by hearing the emergency sound generated from the emergency dispatcher 500.

In the above, the use of civil defense alarms already installed in each region in order to prepare for civil defense incidents as the emergency dispatcher 500 has been described. However, the emergency dispatcher 500 may be separately provided and installed. At this time, the emergency dispatcher 500 is installed so as to be located below the second reference distance in each of the plurality of landing sites stored in the landing location determination unit 132. Then, the location of the installed emergency dispatcher 500 is stored in the emergency dispatcher selection unit 136 .

The controller 200 may include an operation unit that controls or controls the operation of the vehicle 100 or monitors the state of the vehicle 100, a transmitter that transmits a signal to the outside, and a receiver that receives an external signal.

The transmitting unit may transmit, for example, a signal generated by the operation unit to the receiving unit of the vehicle 100. And the receiving unit may receive a signal transmitted from the transmitting unit of the vehicle 100, for example.

The operating unit may be a means for controlling the operation of the vehicle 100 or monitoring its condition. For example, the operating unit may transmit take-off, landing, and flight speed control commands to the vehicle 100 or transmit a flight path. In addition, the operation unit may display on the screen data included in the signal transmitted from the aircraft 100, for example, a photograph obtained from a photographing unit provided in the vehicle, and location data obtained from a location sensor. In addition, the operation unit may determine the current state of the aircraft and transmit commands necessary for the operation of the aircraft to the driving control unit of the aircraft according to the determined result.

Such a controller 200 may be implemented in the form of a control computer and a control program loaded on the control computer. Of course, the manner in which the controller 200 is implemented may vary. This controller 200 may be installed on the ground, for example. And the controller 200 may mean any one of a control device, an air traffic controller, an air traffic control center, an operation controller, and an operation control center.

In the above, it has been described that the aircraft 100 includes the emergency landing notification device 130. However, it is not limited thereto, and the controller may include an emergency landing notification device 130. In this case, the emergency landing notification device 130 provided in the controller 200 operates to transmit an emergency landing notification message to the terminal 400, and the emergency dispatcher 500 operates to generate an emergency notification sound. . That is, the detection signal or detection data of the flight drive unit 120 detected by the sensor provided in the vehicle 100 may be transmitted to the controller 200 installed on the ground. This may be transmitted to the receiver provided in the controller 200 through the transmitter provided in the vehicle 100.

Then, the emergency landing determination unit 131 provided in the controller 200 determines whether or not an emergency landing of the vehicle 100 is necessary. In addition, when the emergency landing determination unit 131 determines that an emergency landing of the aircraft 100 is necessary, the landing location determination unit 132 determines the landing field where the aircraft 100 is to land, and the communication base station selection unit 134 ) to select a communication base station. And the message generating unit 133 generates an emergency landing notification message. Then, the message transmission unit 135 transmits the generated emergency landing notification message using the selected communication base station 300 . Therefore, before the aircraft 100 lands at the determined landing site, an emergency landing notification message is transmitted to the terminal 400 located around the determined landing site.

In addition, when the emergency landing determination unit 131 determines that an emergency landing of the aircraft 100 is necessary, the emergency dispatcher selection unit 136 selects the emergency dispatcher 500 to generate an emergency announcement sound. Thereafter, the emergency sound generation control unit 137 controls the operation of the selected emergency sound dispatcher 500 to generate an emergency sound. Therefore, before the vehicle 100 lands at the determined landing site, an emergency notification sound, for example, a siren, is generated or output from the emergency dispatcher 500 around the determined landing site.

In the above, when it is determined that an emergency landing of the vehicle 100 is necessary, the emergency landing notification device 130 transmits an emergency landing notification message to the terminal 400 (first emergency notification), and the emergency dispatcher 500 It has been described that both types of emergency notifications that generate an emergency notification sound (second emergency notification) are performed. However, the emergency landing notification device 130 may be operated to perform any one of the first emergency notification and the second emergency notification among the above-described emergency notifications.

6 is a flowchart illustrating the operation of an emergency landing notification device according to an embodiment of the present invention.

Hereinafter, the operation of the emergency landing notification device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6 .

When the aircraft 100 takes off and starts to fly (S10), the sensor detects or detects the operation of the flight drive unit 120 (S20). Then, the emergency landing determining unit 131 of the emergency landing notification device 130 determines whether or not it is necessary to make an emergency landing of the aircraft by using the signal detected by the sensor (S30).

For example, each of the first to fourth loader sensors detects the number of revolutions of the first to fourth loaders 121a to 121d. Signals or data detected by each of the first to fourth loader sensors are transmitted to the emergency landing determining unit 131 of the emergency landing notification device 130 . And the emergency landing determining unit 131 determines whether or not the vehicle 100 is abnormal and whether an emergency landing is required by using data transmitted from each of the first to fourth loader sensors. That is, when the difference between the first to fourth rotation speeds detected by each of the first to fourth loader sensors is less than or equal to the first reference rotation speed difference, the emergency landing determining unit 131 determines that there is no abnormality in the aircraft 100. . Accordingly, the emergency landing determination unit 131 determines that there is no need to make an emergency landing of the aircraft 100 (No). However, when the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference, the emergency landing determination unit 131 determines that there is something wrong with the vehicle 100. At this time, if the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference and is less than the second reference rotation speed difference, the emergency landing determination unit 131 determines that an abnormality has occurred in the vehicle 100, but an emergency landing is required. Decide no (no). However, when the difference between the first to fourth rotation speeds exceeds the first reference rotation speed difference and exceeds the second reference rotation speed difference, the emergency landing determination unit 131 determines that an emergency landing is necessary (Yes).

If it is determined that an emergency landing is necessary (Yes), the landing location determination unit 132 determines the location, that is, the landing site for emergency landing of the vehicle 100 (S40). At this time, the landing location determining unit 132 selects a landing site located closest to the current position of the aircraft 100 among a plurality of landing sites as a landing site to land the aircraft 100. Here, the current position of the vehicle 100 may be a position detected by a position sensor, and may include an altitude and a horizontal position.

When the landing site for emergency landing of the vehicle 100 is determined, the message generation unit 133 generates an emergency landing notification message (S52). At this time, the message generating unit 133 generates a message including the location of the determined landing site, for example, an address. In addition, the message generator 133 may generate a message to further include at least one of the name of the determined landing site and the predicted landing time.

In addition, when the landing site for emergency landing of the aircraft 100 is determined, the communication base station selector 134 selects a communication base station to be used for transmitting the emergency landing notice message (S51). At this time, the communication base station selector 134 selects, for example, a communication base station located or installed at a distance less than the first reference distance from the determined landing site among a plurality of stored communication base stations.

The steps of generating an emergency landing notice message and selecting a communication base station may be performed in no particular order. That is, it is possible to select a communication base station after generating the emergency landing notification message, generate an emergency landing notification message after selecting the communication base station, or simultaneously generate the emergency landing notification message and select the communication base station.

When the emergency landing notification message is generated and the communication base station is selected, the message transmitter 135 transmits the emergency landing notification message using the selected communication base station (S53). Accordingly, an emergency landing notification message is sent or transmitted to the terminal 400 connected to the communication signal to the selected or used communication base station 300 . In other words, an emergency landing notification message is transmitted to the terminal 400 within a predetermined distance from the selected communication base station 300 . Therefore, people around the landing site where the aircraft 100 will make an emergency landing can receive the emergency landing notification message received through the terminal 400 and prepare for the landing of the aircraft 100 in advance.

While the emergency landing notification message is generated and transmitted to the terminal 400, the emergency dispatcher 500 may generate an emergency notification sound. To this end, when the emergency landing location is determined, the emergency dispatcher selection unit 136 selects the emergency dispatcher to be used using the location of the landing site determined by the landing location determination unit 132 (S61). That is, the emergency dispatcher selection unit 136 selects the emergency dispatcher 500 located or installed at a distance less than the second reference distance from the determined landing site.

When the emergency dispatcher 500 is selected, the emergency sound generation controller 137 generates an emergency notification sound from the selected emergency dispatcher 500 (S62). That is, the emergency announcement sound generation control unit 137 controls the operation of the emergency dispatcher 500 selected so that an emergency announcement sound notifying the emergency landing of the aircraft 100 is generated. Accordingly, an emergency sound is generated from the emergency dispatcher 500 installed around the landing field where the vehicle 100 is to land or installed within a predetermined distance. Therefore, people around the landing site where the aircraft 100 will make an emergency landing can prepare in advance before landing the aircraft 100 by hearing the emergency sound generated from the emergency dispatcher 500.

As described above, according to the embodiments of the present invention, the first emergency notification that transmits the emergency landing notification message to the terminal 400 around the landing field before the aircraft makes an emergency landing and the first emergency notification device that generates an emergency notification from the emergency dispatcher 500 At least one of 2 emergency notifications may be issued.

Therefore, people around the emergency landing site can be evacuated in advance before the aircraft 100 makes an emergency landing. Accordingly, it is possible to prevent or suppress a safety accident, that is, the occurrence of human casualties due to the emergency landing of the aircraft 100.
