Referring to FIGS. 1 to 4, the drone control system for managing road operation according to the present invention includes a drone 100 and a control center 200.

The drones 100 automatically detect the road state information, the emergency situation information, the traffic situation information, the weather information, and the like in the corresponding flight path while automatically flying the flight path set by the control center 200.

The drone 100 includes a flight module 110, a sensing module 120, a memory 130, a battery 140, a control module 150, and a signal output module 160.

The flight module 110 executes the flight operation on the flight path on the road determined by the automatic navigation data. The flight module 110 includes components required for flight of the drones 100, including motors, propellers, and the like. The automatic navigation data used for the automatic flight of the drones 100 includes the flight speed, the flying distance, the steering angle, the flight altitude, and the like of the drones 100, and may include coordinate values passing through time.

The sensing module 120 performs a sensing operation during operation of the flight module 110, that is, while the drones 100 are flying.

The sensing module 120 includes sensors for sensing weather information such as temperature, pressure, humidity, wind direction, wind speed, and precipitation in a flight path on the road, and also acquires road state information, emergency situation information, And a camera for photographing the road and the vehicle in the flight path.

The memory 130 stores sensing data according to a sensing operation of the sensing module 120, that is, information sensed by sensors provided in the sensing module 120, and an image captured by the camera. In addition, the memory 130 stores automatic navigation data for setting the flight path of the drones 100.

The battery 140 supplies operating power to the flight module 110 and the sensing module 120.

The control module 150 controls the flight operation of the flight module 110 using the automatic navigation data stored in the memory 130.

The control module 150 controls the first to fourth modes in controlling the flight operation of the flight module 110. [ The drones 100 may include a distance sensor or an altitude sensor for preventing collision with an obstacle. When the possibility of collision is detected by the sensors, To-4 mode in order to avoid a collision even if a flight operation is performed.

The first mode is a mode for controlling the flight module 110 to fly at a predetermined altitude while keeping the determined flight path according to a predetermined data value of the automatic navigation data. In the first mode, the flight path, flight speed and flight altitude are not changed in any situation on the road.

The second mode is a mode for controlling the flight module 110 to pass through at least one specific observation point set in the automatic navigation data while flying in the first mode. In the second mode, it is possible to control to fly at the flight height and speed set in the automatic navigation data at a specific observation point.

The third mode is to fly in the first mode and periodically check the charged amount of the battery 140 to calculate the flying distance of the drones 100 according to the charged amount of the battery 140. [ Then, it is a mode for resetting the flight path according to the automatic navigation data based on the calculated possible flying distance with respect to the calculated charging amount. The third mode is for preventing the drone 100 from falling when the flying distance of the battery 140 is smaller than the distance of the flight path set to fly in the first mode. In such a case, Mode, and controls the flight operation of the flight module 110 after resetting the flight path in the direction of reducing the distance of the flight path set to fly in the mode. For example, if the flight path set to fly in the first mode is a route starting from the control center 200 and returning to the control center 200, the control module 150 sets the charge amount of the battery 140 in the third mode It is possible to automatically set the return time point from the flight path according to the automatic navigation data to the control center 200 based on the flying distance of the drone 100. Since the distance of the flight path set to fly in the first mode is shortened by accelerating the return time of the drones 100, it is possible to prevent the drones 100 from falling due to power shortage.

The fourth mode is a mode in which the flight path according to the first mode is followed by the returning of the flight path according to the first mode after tracking a specific vehicle on the road for a predetermined time. The control module 150 identifies the illegal vehicle on the road from the image photographed by the detection module 120 in the fourth mode and tracks the illegal vehicle as shown in FIG. 4 for a predetermined tracking time And controls the flight operation of the flight module 110. Then, the control module 150 transmits the vehicle information and the regulation violation information to the control center 200 from the image photographed by the detection module 120 while tracking the illegal vehicle during the tracking time.

For example, the control module 150 can determine the speeding vehicle on the road from the image photographed by the sensing module 120. Accordingly, the control module 150 controls the flight operation of the flight module 110 to track the overspeed vehicle for a predetermined tracking time. Also, the control module 150 transmits the vehicle information and the speed information for the overspeed vehicle to the control center 200 from the image photographed by the sensing module 120. Then, the control module 150 controls the flight operation of the flight module 110 to return to the flight path according to the first mode determined by the automatic navigation data after the tracking time has expired.

The signal output module 160 transmits a predetermined warning signal or outputs a predetermined warning sound. Particularly, the signal output module 160 is for transmitting a warning message to the illegal vehicle on the road. In the fourth mode, when the drones 100 track the illegal vehicle during the preset tracking time, The signal is transmitted toward the illegal vehicle or a predetermined warning sound is output. For example, the signal output module 160 can output a warning signal or a warning sound indicating that the drone 100 is overspeed toward the overspeed vehicle while the drone 100 tracks the overspeed vehicle during the tracking time.

The control center 200 includes a communication module 210, a storage device 220, a charging device 230, and a control device 240.

The communication module 210 couples communication with the drones 100. The communication module 210 transmits automatic navigation data to the drones 100 through a communication connection with the drones 100 and receives sensing data from the drones 100. [ In particular, it is possible to receive a photographed image of a camera provided in the drone 100 in real time.

The storage device 220 stores an automatic navigation program for setting data values of automatic navigation data stored in the memory 130 of the drones 100 and stores sensing data received through the communication module 210.
