Description

TECHNICAL FIELD [0001] The present invention relates to an emergency communication apparatus and method using a TV white space,

The present invention relates to an emergency communication apparatus and method using a TV white space, and more particularly, to an emergency communication apparatus and method using a TV whitespace that can transmit an emergency situation by updating current available channel information based on available channel information And an emergency communication apparatus and method.

Conventionally, a communication system between vehicles has been used when a vehicle in which an accident has occurred transmits an emergency situation. Conventional communication methods between vehicles are such as 2.4 GHz Bluetooth, Wi-Fi, and wireless LAN. However, since a large number of access points are required to use the above-described conventional communication method between vehicles, there arises a problem of an increase in the construction cost. In addition, the above-described communication method has a problem that the propagation characteristics are deteriorated (the radio wave transmission / reception distance is 100 m at maximum), and the emergency situation can not be transmitted to a wider coverage area. In addition, the above-described communication method has a problem that it is not suitable for a vehicle communication service that requires emergency communication due to serious interference.

Accordingly, studies using TV whitespace in providing communication services between vehicles are underway.

TV whitespace, that is, TV idle band, means an empty frequency band that is not used locally in the broadcast band. TV White Space may vary in available channels depending on the time of administration. Thus, the TV white space must be updated.

Conventionally, the following process has been performed to update the TV white space.

For example, a vehicle located in the administrative area A connected to the TV white space database through a TV white space access point, received and updated available channel information, and used it. At this time, the vehicle can transmit its own location information (using GPS location information) to the TV white space access point and receive the available channel information.

However, if access to the TV white space access point is not possible, the vehicle will not be able to access the TV white space database and therefore will not be able to update the TV white space. Accordingly, the vehicle can not communicate using the TV white space.

1 is a diagram schematically illustrating a configuration of an emergency communication apparatus according to an embodiment of the present invention.

The emergency communication device 100 according to an embodiment of the present invention can be mounted on a vehicle. The emergency communication device 100 updates the available channel information, and when an emergency situation occurs in the vehicle, it can notify an emergency situation to a vehicle existing within the communicationable distance by using the updated available channel.

The vehicle must update the available channel information through a connection with the TV white space access point to communicate using the TV white space. This is because the available channels for TV whitespace may vary by region (by administrative district) and by time. On the other hand, the vehicle can update the available channel information when it is possible to access the TV white space access point. However, if the TV white space access point is not installed near the vehicle, or if the TV white space access point fails, the vehicle can not access the TV white space access point and can not update the TV white space available channel information. Accordingly, the vehicle can not communicate using TV whitespace without updated information in an administrative area using a channel different from the channel currently used. Accordingly, the vehicle can check whether the TV white space available channel information has been updated when the current position moves to a different administrative zone from the previous one, and perform the operation according to whether the TV white space available channel information is updated.

On the other hand, the frequency of the TV white space refers to a band of about 54 MHz to 698 MHz, and is excellent in transmittance and diffraction properties for buildings and obstacles, Tunnels, collapsed buildings can be effectively transmitted in accident sites, buildings, and surrounding areas.

Referring to FIG. 1, the emergency communication apparatus 100 includes an update checking unit 110, an update executing unit 120, an emergency situation recognition unit 130, and a communication unit 140.

The update checking unit 110 checks whether TV white space available channel information is updated. When the vehicle is moving, the update checking unit 110 can check whether the TV white space available channel information has been updated after the vehicle has passed the boundary of the area. The update checking unit 110 can check whether the TV whitespace available channel information has been updated within a predetermined time after the vehicle has passed the boundary of the area (the boundary between the administrative spaces, i.e., the boundary line). When the update checking unit 110 confirms whether the TV white space available channel information is updated, the vehicle can perform communication with another vehicle existing within the communication distance based on the updated TV white space available channel information.

On the other hand, if the update checking unit 110 can not confirm whether or not updating TV whitelist-enabled channel information, the update executing unit 120 may operate as follows.

If the update checking unit 110 determines that the available channel information is not updated, the update executing unit 120 may update the current available channel information based on the available channel information that has been used in the past. The update executing unit 120 updates the available channel information based on the available channel information that has been used in the past in consideration of the location information and the time information of the vehicle when the update checking unit 110 determines that the available channel information is not updated The available channel information can be updated. For example, when the TV white space available channel information can not be updated, the TV white space access point may not be installed near the vehicle, or the TV white space access point may be broken. Therefore, the update executing unit 120 The available channel information at the current location can be updated based on the available channel information that has been used in the past.

The emergency situation sensing unit 130 can recognize when an emergency situation occurs in the vehicle. The emergency situation recognition unit 130 can recognize an emergency situation occurring in the vehicle through the sensor. The emergency situation occurring in the vehicle is as shown in Fig.

3 is a view schematically showing emergency situations occurring in a vehicle according to an embodiment of the present invention.

Referring to FIG. 3, emergency situations that may occur in a vehicle may be various, and an emergency situation may be recognized through a sensor. For example, the type of emergency can be rollover, shock, fire, battery capacity, fuel shortages, and the like. At this time, the above-described emergency situation can be recognized by a separate sensor. For example, vehicle rollover may be perceived by a gyro sensor, and the occurrence of an impact may be perceived by the impact sensor. Further, the fire occurrence can be recognized by the fire sensor, and the battery capacity shortage can be recognized by the battery capacity sensor, and the fuel shortage can be recognized by the fuel capacity sensor. Meanwhile, as described above, the emergency situations recognized by the various sensors can be transmitted to the traffic control system through the communication unit 140. In the traffic control system, the types of the received emergency situations can be distinguished and emergency situations can be solved The contents can be transferred to the system.

The communication unit 140 can transmit the emergency situation to the vehicle within the communication coverage based on the updated available channel information. In addition, the communication unit 140 may receive an emergency situation from another vehicle within the communication coverage range, and may transmit the received emergency situation to another vehicle based on the available channel information.

FIG. 6 is a diagram illustrating an administrative area according to an embodiment of the present invention. FIG. 1 is a view schematically showing an emergency situation occurrence position of a vehicle according to an example.

In describing FIG. 2, the components having the same reference numerals as those of FIG. 1 include all the functions and operations described with reference to FIG. 1, and therefore, a detailed description thereof will be omitted.

Referring to FIG. 2, the emergency communication apparatus 100 according to the present embodiment may further include a position determination unit 210 and a movement path confirmation unit 220.

When the emergency recognition unit 130 recognizes an emergency situation, the location determination unit 210 can confirm the location of the vehicle where the emergency has occurred. When the emergency situation recognition unit 130 recognizes an emergency situation, the location determination unit 210 can determine whether the location where the emergency occurred is included in a boundary area having a predetermined radius range from the boundary line between the plurality of areas have. On the other hand, the position determination unit 210 can determine the current position based on the GPS information. On the other hand, the boundary region according to the present embodiment can be preset in advance. A boundary region may refer to a region having a predetermined radius range from a boundary where two neighboring regions are in contact with each other. The border area can be set in consideration of the service transmission range of the TV white space. For example, if the service transmission range of the TV white space is 10 km, the diameter of the range set as the border area may be 20 km. For example, as shown in FIG. 6, in the case of Seoul, there may be a plurality of administrative districts (for example, Yeongdeungpo, Gwanak, Seongdong, and the like), and Yeongdeungpo and Gwanak are administrative districts A and B, The boundary area SA can be set to a predetermined radius range based on a line (e.g., a boundary line between the two zones) SL that bounds the gwanakgu. In describing the present embodiment, the administrative districts are described as the districts included in the city of Seoul, but the present invention is not limited thereto, and Seoul, Gyeonggi-do, Incheon and the like may be classified as administrative districts. 7A and 7B, the position determination unit 210 may determine the position of the vehicle EC in which an emergency occurs, based on the GPS information. FIG. 7A is a diagram illustrating a case where a vehicle EC in which an emergency occurs is located in a boundary area SA, and FIG. 7B is a diagram illustrating a case where a vehicle EC in which an emergency occurs is out of a boundary area SA.

The movement path confirmation unit 220 can confirm the movement path of the vehicle in which an emergency occurs. When the position determination unit 210 determines that the position where the emergency situation occurs is included in a boundary area having a predetermined radius range from a boundary line between a plurality of areas, You can check the path. For example, the movement path confirmation unit 220 can confirm the movement path of the vehicle based on the running record and / or the GPS information. In addition, the movement path confirmation unit 220 can check the movement path of the vehicle in conjunction with navigation (not shown).

When the position determination unit 210 determines that the position where the emergency occurs is included in a boundary area having a predetermined radius range from the boundary line between the plurality of zones, You can check the route. In this case, when it is ascertained that the vehicle in which the emergency has occurred has moved from the boundary line between a plurality of zones and a zone including a part of the boundary zone having a predetermined radius range, May additionally update the channel information used in the area where the vehicle in which the emergency has occurred, to the available channel information. The reason for operating as described above is that when there are two neighboring areas including the boundary area (refer to Fig. 6, Yeongdeungpo and Gwanak-gu), when the accident location of the vehicle is a gwanak-gu, Can update the available channel information in the gwanak-gu, and can perform communication with the vehicles existing in the gwanak-gu based on the updated channel information. However, when there is a vehicle for emergency communication in Yeongdeungpo-gu, the currently updated available channel information can not be communicated with a vehicle existing in Yeongdeungpo-gu because it is available channel information of Gwanak-gu. In this case, when it is ascertained that the vehicle in which the emergency has occurred has moved from the boundary line between a plurality of zones and a zone including a part of the boundary zone having a predetermined radius range, ) Can additionally update the channel information used in the corresponding area where the vehicle in which the emergency has occurred, that is, Yeongdeungpo-gu, to the available channel information, so that the accident vehicle can communicate with the vehicle existing in Yeongdeungpo-gu.

When the position determination unit 210 determines that the position where the emergency situation occurs is included in the boundary area having the predetermined radius range from the boundary line between the plurality of zones, the movement route confirmation unit 220 determines that the emergency situation has occurred The moving route of the vehicle can be confirmed. In this case, when it is confirmed that the vehicle in which an emergency has occurred has moved from another zone that does not include a part of the boundary area having a predetermined radius range from the boundary line between the plurality of zones, The controller 120 may additionally update the current available channel information based on the available channel information that has been used in the past including the part of the boundary area except for the area where the vehicle in which the emergency occurred. The reason for operating as described above is that, when there are two neighboring zones (administrative zone A and administrative zone B) including the boundary zone, when the accidental position of the vehicle is the administrative zone B, May update the available channel information in administrative area B and may communicate with vehicles in administrative area B based on the updated channel information. However, if there is a vehicle for the emergency communication in the administrative area A and wants to communicate, the currently updated available channel information is the available channel information of the administrative area B, so communication with the vehicle existing in the administrative area A is performed I can not. In this case, when it is confirmed that the vehicle in which an emergency has occurred has moved from another zone that does not include a part of the boundary area having a predetermined radius range from the boundary line between the plurality of zones, Based on available channel information previously used in a zone (administrative zone A) including a part of the boundary zone excluding the zone (administrative zone B) where the vehicle in which the emergency situation occurred, among the boundary zones, By additionally updating the information, the accident vehicle can also communicate with the vehicle present in the administrative zone A.
