자동차(1)가 직접 기지국(4)과 통신하기 어려운 음영 지역(예를 들면, 산악 지역 등 통신이 취약한 지역)에 위치할 경우, 무인 비행체(2)가 비행하여 기지국(4)과 신호를 송수신할 수 있는 위치로 이동하고, 자동차(1)는 무인 비행체(2)를 통해 기지국(4)과 신호를 송수신한다. 이때, 무인 비행체(2)는 제2 통신부(32)를 통해 기지국(4)과 신호를 송수신할 수 있다. 예를 들면, 자동차(1)는 무인 비행체(2)와 별도의 통신 채널을 통해 신호를 송수신할 수 있으며, 무인 비행체(2)는 제2 통신부(32)를 통해 기지국(4)으로 자동차(1)에서 수신한 신호를 송신하거나, 제2 통신부(32)를 통해 기지국(4)으로부터 수신한 신호를 자동차(1)로 송신할 수 있다.When the vehicle 1 is located in a shaded area (for example, an area where communication is vulnerable, such as a mountainous area) where it is difficult to directly communicate with the base station 4, the unmanned aerial vehicle 2 flies to transmit and receive signals to and from the base station 4 Move to a position that can be, and the vehicle 1 transmits and receives signals to and from the base station 4 through the unmanned aerial vehicle 2. At this time, the unmanned aerial vehicle 2 may transmit and receive signals to and from the base station 4 through the second communication unit 32. For example, the vehicle 1 may transmit and receive a signal through a separate communication channel with the unmanned aerial vehicle 2, and the unmanned aerial vehicle 2 may transmit the vehicle (1) to the base station 4 through the second communication unit 32. ) Can be transmitted, or the signal received from the base station 4 through the second communication unit 32 can be transmitted to the vehicle 1.
도 3은 본 발명의 일실시예에 따른 자동차의 신호 송수신 방법을 설명하기 위한 동작 흐름도이다.3 is an operation flowchart for explaining a method for transmitting and receiving a signal in a vehicle according to an embodiment of the present invention.
도 3에 나타낸 자동차의 신호 송수신 방법은 자동차에 장착된 제어부(미도시)에 의해 수행될 수 있다.The signal transmission / reception method of the vehicle illustrated in FIG. 3 may be performed by a control unit (not shown) mounted on the vehicle.
먼저, 자동차가 음영 지역에 위치하고 있는지 여부를 판단한다(S110 단계). 여기서, 도 2에서 설명한 것과 같이, 자동차에서 기지국과 직접적으로 신호를 송수신하기 어려운 지역을 의미한다. 자동차의 제어부는 제1 통신부(도 1의 31)를 통해 수신되는 신호의 세기 등을 기초로 자동차가 음영 지역에 위치하는지 여부를 판단할 수 있다.First, it is determined whether the vehicle is located in a shaded area (step S110). Here, as described in FIG. 2, it means an area in which it is difficult for a vehicle to directly transmit and receive signals with a base station. The controller of the vehicle may determine whether the vehicle is located in a shaded area based on the strength of a signal received through the first communication unit (31 of FIG. 1).
S110 단계에서 자동차가 음영 지역에 위치하지 않는다고 판단한 경우, 제1 통신부(도 1의 31)를 통해 기지국 등과 신호를 송수신한다(S120 단계).If it is determined in step S110 that the vehicle is not located in the shaded area, a signal is transmitted / received to / from the base station through the first communication unit (31 in FIG. 1) (step S120).
S110 단계에서 자동차가 음영 지역에 위치한다고 판단한 경우, 자동차는 무인 비행체를 비행시킨다(S130 단계). 구체적으로, 자동차는 무인 비행체가 자동차와 신호를 송수신할 수 있음과 동시에, 기지국 등과도 신호를 송수신할 수 있는 위치까지 무인 비행체를 비행시킬 수 있다. 경우에 따라, S130 단계는 자동차가 음영 지역에서 사고 등 긴급 상황에 처해진 경우에 수행될 수도 있다.If it is determined in step S110 that the vehicle is located in the shaded area, the vehicle flies the unmanned aerial vehicle (step S130). Specifically, the vehicle can fly the unmanned aerial vehicle to a position where the unmanned aerial vehicle can transmit and receive signals to and from the vehicle and at the same time transmit and receive signals with the base station. In some cases, step S130 may be performed when the vehicle is in an emergency situation such as an accident in a shaded area.
다음으로, 무인 비행체는 제2 통신부(도 1의 32)를 통해 기지국 등과 신호를 송수신하고, 자동차는 이러한 무인 비행체를 통해 기지국 등과 신호를 송수신할 수 있다(S140 단계). 이를 위해, 무인 비행체는 자동차의 통신 시스템과 공유 가능한 안테나를 내장할 수 있다.Next, the unmanned aerial vehicle transmits and receives signals to and from the base station through the second communication unit (32 of FIG. 1), and the vehicle can transmit and receive signals to and from the base station through the unmanned aerial vehicle (step S140). To this end, the unmanned aerial vehicle may incorporate an antenna that can be shared with the vehicle's communication system.
이러한 기능을 수행함으로써, 자동차의 위치가 음영 지역에 위치하더라도 기지국과 통신이 가능해진다. 따라서, 자동차가 음영 지역에서 사고 등 긴급 상황에 처해진 경우에도 보다 빠른 긴급 구조 활동 등을 수행할 수 있게 된다.By performing this function, it is possible to communicate with the base station even if the vehicle is located in a shaded area. Therefore, even when the vehicle is in an emergency situation such as an accident in a shaded area, it is possible to perform more rapid emergency rescue activities.
도 4는 본 발명의 일실시예에 따른 자동차의 전력 송신 기능을 설명하기 위한 도면이다.4 is a view for explaining a power transmission function of a vehicle according to an embodiment of the present invention.
본 발명의 일실시예에 따르면, 자동차(1)가 진행중이거나 정차인 상태에서, 비행중인 무인 비행체(2)로 전력을 송신할 수 있다. 이때, 자동차(1)는 자동차(1)와 무인 비행체(2) 사이의 거리에 따라 전력 송신의 파라미터를 조정할 수 있다. 전력 송신의 파라미터는 충전/방전비율(CDR : charge discharge rate), 시분할율(TDR : time division rate), 에너지/주파수 비율(EFR : energy frequency rate), 및 충전 방식 변환(CMS : charging method change) 등을 포함할 수 있다.According to an embodiment of the present invention, while the vehicle 1 is in progress or stopped, power can be transmitted to the unmanned flying vehicle 2 in flight. At this time, the vehicle 1 may adjust the parameters of power transmission according to the distance between the vehicle 1 and the unmanned aerial vehicle 2. The parameters of the power transmission include charge discharge rate (CDR), time division rate (TDR), energy frequency rate (EFR), and charging method change (CMS) And the like.

For example, an image in front of the vehicle 1 may be photographed and provided to the vehicle 1. At this time, the unmanned aerial vehicle 2 determines an area to be photographed based on driving information (for example, route information according to navigation, etc.) from the car 1, and photographs the determined area to be provided to the car 1 You can. In addition, as described with reference to FIGS. 1 to 3, the unmanned aerial vehicle 2 may support the vehicle 1 to transmit and receive signals to and from a base station when the vehicle 1 is located in a shaded area.
도 5는 본 발명의 일실시예에 따른 자동차의 전력 송신 방법을 설명하기 위한 도면이다. 5 is a view for explaining a power transmission method of a vehicle according to an embodiment of the present invention.
도 5에 나타낸 자동차의 전력 송신 방법은 자동차에 장착된 제어부(미도시)에 의해 수행될 수 있다.The power transmission method of the vehicle shown in FIG. 5 may be performed by a control unit (not shown) mounted on the vehicle.
먼저, 무인 비행체와 자동차 사이의 거리를 파악한다(S210 단계). S210 단계에서는, 다양한 형태의 거리 센서를 이용하거나, 무인 비행체와 자동차 사이에 송수신되는 신호의 세기 등에 기초하는 등 다양한 방법으로 무인 비행체와 자동차 사이의 거리를 파악할 수 있다.First, grasp the distance between the unmanned aerial vehicle and the vehicle (step S210). In step S210, the distance between the unmanned aerial vehicle and the vehicle may be grasped in various ways, such as by using various types of distance sensors or based on the strength of signals transmitted and received between the unmanned aerial vehicle and the vehicle.
다음으로, 파악한 거리에 따라 무선 전력 전송 및 통신과 관련된 다양한 파라미터들 중 적어도 하나 이상을 설정함으로써, 무선 전력 전송 및 통신과 관련된 환경을 설정할 수 있다(S220 단계).Next, an environment related to wireless power transmission and communication may be set by setting at least one of various parameters related to wireless power transmission and communication according to the identified distance (step S220).
다음의 표 1은 S220 단계에서 설정될 수 있는 파라미터의 예를 나타낸 것이다.Table 1 below shows examples of parameters that can be set in step S220.
거리Street 가깝다 멀다Near and far
CDR (충전/방전)CDR (charge / discharge) 1.51.5 1.21.2 1One 0.90.9
TDR (충전/시간)TDR (charge / hour) 0.990.99 0.90.9 0.50.5 통신Communication

즉, 무인 비행체와 자동차 사이의 거리가 가까우면 충전/방전 비율을 크게 설정하고, 거리가 멀면 충전/방전 비율을 작게 설정할 수 있다. 여기서, 충전/방전 비율은 무인 비행체의 배터리에서, 방전되는 에너지에 대한 충전되는 에너지의 비율을 의미한다. That is, if the distance between the unmanned aerial vehicle and the vehicle is close, the charge / discharge ratio can be set large, and if the distance is far, the charge / discharge ratio can be set small. Here, the charge / discharge ratio means a ratio of energy charged to energy discharged in a battery of an unmanned aerial vehicle.
예를 들면, 무인 비행체와 자동차 사이의 거리가 가까우면 충전/방전 비율이 상대적으로 커지도록 무인 비행체의 배터리에서 소모되는 양보다 많은 양의 전력을 무인 비행체로 전송하고, 무인 비행체와 자동차 사이의 거리가 멀어질수록 무인 비행체로 전송되는 전력의 양을 감소시킬 수 있다.For example, when the distance between the unmanned aerial vehicle and the vehicle is close, the amount of power consumed by the battery of the unmanned aerial vehicle is transmitted to the unmanned aerial vehicle so that the charging / discharging ratio is relatively large, and the distance between the unmanned aerial vehicle and the vehicle. As the distance increases, the amount of power transmitted to the unmanned aerial vehicle may be reduced.
또는, 충전/방전 비율을 이용하여 무인 비행체를 제어할 수도 있다. 예를 들어, 무인 비행체의 배터리의 잔량이 부족하면, 무인 비행체와 자동차 사이의 거리가 충전/방전 비율이 1인 거리 이하가 되도록 무인 비행체를 제어할 수도 있다.Alternatively, the unmanned air vehicle may be controlled using a charge / discharge ratio. For example, if the remaining battery power of the unmanned aerial vehicle is insufficient, the unmanned aerial vehicle may be controlled such that the distance between the unmanned aerial vehicle and the vehicle is less than or equal to a distance of 1 charge / discharge rate.
또는, 무인 비행체와 자동차 사이의 거리에 따라 시분할율을 조정할 수도 있다. 여기서, 시분할율은 통신과 충전이 수행되는 전체 시간 중 충전이 수행되는 시간의 비율을 의미한다. 예를 들어, 무인 비행체와 자동차 사이의 거리가 가까우면, 충전을 수행하는 시간을 충분히 증가시켜 무인 비행체로 전송되는 전력이 커지도록 할 수 있다. 무인 비행체와 자동차 사이의 거리가 멀어지면, 충전을 수행하는 시간은 감소시키고, 통신을 수행하는 시간을 증가시킬 수 있다. 무인 비행체와 자동차 사이의 거리가 일정 거리 이상 멀어지면, 전력 전송은 중단하고 통신만 수행할 수도 있다.Alternatively, the time division rate may be adjusted according to the distance between the unmanned aerial vehicle and the vehicle. Here, the time division rate means the ratio of the time during which charging is performed out of the total time during which communication and charging are performed. For example, when the distance between the unmanned aerial vehicle and the vehicle is close, the time to perform charging is sufficiently increased to increase the power transmitted to the unmanned aerial vehicle. When the distance between the unmanned aerial vehicle and the vehicle increases, the time for performing charging may be reduced and the time for performing communication may be increased. If the distance between the unmanned aerial vehicle and the vehicle is greater than a certain distance, the power transmission may be stopped and only communication may be performed.
또는, 무인 비행체와 자동차 사이의 거리에 따라 에너지/주파수 비율을 조정할 수 있다. 여기서, 에너지/주파수 비율은 기준 주파수(예를 들면, 5.8GHz)에서 전송되는 에너지를 1로 보았을 때, 다른 주파수에서 전달되는 에너지의 상태적인 양을 의미한다. 즉, 무인 비행체와 자동차 사이의 거리가 가까우면, 전력 전송에 사용되는 주파수를 감소시키면서 동시에 전송되는 에너지의 양이 증가되도록 전력 전송 동작을 제어할 수 있다. 무인 비행체와 자동차 사이의 거리가 멀어질수록 전력 전송에 사용되는 주파수는 증가시키면서, 전송되는 에너지의 양은 감소되도록 전력 전송 동작을 제어할 수 있다. 무인 비행체와 자동차 사이의 거리가 일정 거리 이상 멀어지면, 전력 전송은 중단될 수 있다.Alternatively, the energy / frequency ratio can be adjusted according to the distance between the unmanned aerial vehicle and the vehicle. Here, the energy / frequency ratio means a state amount of energy transmitted from another frequency when energy transmitted at a reference frequency (eg, 5.8 GHz) is viewed as 1. That is, when the distance between the unmanned aerial vehicle and the vehicle is close, the power transmission operation may be controlled so as to increase the amount of energy transmitted at the same time while reducing the frequency used for power transmission. As the distance between the unmanned aerial vehicle and the vehicle increases, the power transmission operation may be controlled such that the frequency used for power transmission increases while the amount of energy transmitted decreases. If the distance between the unmanned aerial vehicle and the vehicle is more than a certain distance, power transmission may be stopped.
또는, 무인 비행체와 자동차 사이의 거리에 따라 충전 방식을 변경할 수 있다. 예를 들면, 무인 비행체와 자동차 사이의 거리가 충분히 가깝다면 유도 충전 방식(예를 들면, WPC(Wireless Power Consortium) 표준에 따른 충전 방식)으로 전력을 전송할 수 있다. 무인 비행체와 자동차 사이의 거리가 멀어짐에 따라 공진 방식(예를 들면, A4WP(Alliance for Wireless Power) 표준에 따른 충전 방식), RF 및 IR을 복합하여 전력을 전송하는 RF/IR 복합 방식, 및 IR을 이용하여 전력을 전송하는 IR 방식 등이 순차적으로 적용될 수 있다.Alternatively, the charging method may be changed according to the distance between the unmanned aerial vehicle and the vehicle. For example, if the distance between the unmanned aerial vehicle and the vehicle is sufficiently close, power may be transmitted by an inductive charging method (for example, a charging method according to the Wireless Power Consortium (WPC) standard). As the distance between the unmanned aerial vehicle and the vehicle increases, a resonance method (for example, a charging method according to the Alliance for Wireless Power (A4WP) standard), an RF / IR composite method for transmitting power by combining RF and IR, and IR Using the IR method for transmitting power may be sequentially applied.
