Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that, in the drawings, the same components are denoted by the same reference symbols as possible. Further, the detailed description of known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some of the elements in the accompanying drawings are exaggerated, omitted, or schematically shown, and the size of each element does not entirely reflect the actual size.

In the following description, the unmanned aerial vehicle will be used in the same sense as the unmanned aerial vehicle. Emergency vehicles will be used to refer to vehicles that move quickly to an established destination in an emergency, such as a fire truck, ambulance, or police car.

1 is a view for explaining a road traffic control method according to various embodiments.

Referring to FIG. 1, reference numeral 100 denotes an unmanned aerial vehicle, and reference numerals 161 to 163 may be vehicles preceding the emergency car amount. In the following description, an emergency vehicle (for example, a fire truck, an ambulance, a police car, etc.) for an emergency structure and an emergency rescue is referred to as an emergency vehicle.

Emergency vehicles can be the main source of traffic signaling that takes longer than the actual turnaround time. It may take a long time to travel even if the emergency vehicle makes an emergency alert and runs with the concession of another preceding vehicle. The main causes are traffic congestion and signaling. In addition, the emergency vehicle travels from behind and is conceded to the preceding vehicle. In this case, it may be difficult for the preceding vehicle to recognize an emergency vehicle traveling in the back, and it may also be difficult to recognize the lane in which the emergency vehicle is traveling.

The unmanned vehicle 100 can fly ahead of the emergency vehicle 150 in a situation where there are many vehicles on the road. For example, the unmanned aerial vehicle 100 can inform the emergency vehicle 150 of the emergency vehicle 150 traveling in front of the emergency vehicle 150 while flying 50M - 100M ahead of the emergency vehicle 150 in the driving lane. Here, the unmanned air vehicle 100 may include an emergency light, a siren, and a traffic light. When the unmanned vehicle 150 is unmanned, the unmanned vehicle 150 may guide the moving vehicle 160 to the general vehicle 160 through a traffic light . For example, in FIG. 1, the unmanned aerial vehicle 100 can display a traffic light that guides a general vehicle 160 traveling in a single lane to a two-lane line while flying in a single lane on which the emergency vehicle 150 travels . Then, the general vehicle 160 changes the driving lane from the first lane to the second lane so that the lane can be conceded to the emergency vehicle 150. Therefore, the emergency vehicle 150 can move quickly while maintaining the driving lane.

In addition, the unmanned air vehicle 100 includes a camera module, and can photograph the topographical object and the preceding vehicle on the route on which the emergency vehicle will travel while flying ahead of the emergency vehicle, and provide the captured image to the emergency vehicle.

According to various embodiments, the emergency vehicle can move quickly by intentionally manipulating the signal in the emergency situation by the unmanned aerial vehicle (100). In addition, since the unmanned air vehicle 100 can grasp road conditions in real time, rescuers can control the situation under fast and leading judgment. For example, using an opposite lane to transport an emergency patient, or forcing it to pass a red light signal can cause another disaster. In this case, unmanned vehicles can be used to control vehicles in opposite lanes, thereby ensuring safe travel routes of emergency vehicles. In addition, since the unmanned aerial vehicle controls the road while flying ahead of the emergency vehicle, the driver of the vehicle traveling ahead of the emergency vehicle can receive the visual instruction together with the auditory siren, so that the emergency and the emergency vehicle The driving lane can be recognized.

For example, the signal lamp 410 of the drones may transmit a signal indicating a moving direction (direction of concession) to a driver of another general vehicle on the road according to a judgment of a person boarding the emergency vehicle. For example, the traffic light 410 may be attached to the lower end of the drones. Under the control of the occupant of the emergency vehicle, the dron preceding the movement path of the emergency vehicle moves at the same speed as the emergency vehicle and can transmit the instruction signal of the signal lamp 410 to the driver on the road. Also, the speaker 421, which can transmit the voice command of the occupant in the emergency car, can transmit the voice direction directing instruction to the driver of the general vehicle directly at a closer location.

CLAIMS 1. A method of controlling traffic of an emergency vehicle in conjunction with a signal controller, an emergency vehicle device, and an unmanned aerial vehicle device,
Generating an unmanned flight command of an unmanned aerial vehicle mounted on a groove of the emergency vehicle device when the emergency vehicle device generates an emergency situation;
Setting the shortest travel route in which the emergency vehicle device has the shortest travel time among the travel routes to the destination;
When the unmanned flight device receives the unmanned flight command from the emergency vehicle device, taking off from the groove of the emergency vehicle device;
Wherein the unmanned flight device shares the shortest route information with the emergency vehicle device and maintains a predetermined distance from the emergency vehicle device based on the shortest travel route information and performs an unmanned flight preceding the traveling of the emergency vehicle ;
Outputting a laser to both lanes of a lane on which the emergency vehicle travels, using the laser generator attached to both sides of the lower end of the unmanned flight device;
And a signal display module mounted on the unmanned flight device, the signal display module being mounted on the unmanned flight device in order to induce concession from the driving lane of the emergency vehicle device to a car of a general vehicle when the unmanned flight device receives signal control information from the emergency vehicle device in the unmanned flight, A right traffic light, and a stop traffic light of the traffic lights;
Wherein when the unmanned flight control apparatus receives the information of the signal controller and the signal indicator on the shortest travel route from the emergency vehicle apparatus in the step of unmanned flight, the signal indicator of the emergency vehicle apparatus, ;
Changing the indication of the signal indicator that the signal controller receives the access information of the emergency vehicle device to a progress indication for proceeding of the emergency vehicle device; And
And returning to the home of the emergency vehicle device in an autonomous flight upon receipt of the emergency situation releasing information from the emergency vehicle device at the step of unmanned flight
And a traffic control method.
