Description

This disclosure relates to a traffic control system.

Currently, there is a growing trend around the world to use drones, which are unmanned aerial vehicles, to deliver packages. For example, Patent Document 1 discloses a package delivery system that uses drones.

JP 2005-263112 A

Incidentally, if drones flying through the air are used to deliver packages in the future, it is expected that drone congestion will occur on aerial delivery routes in large cities. In such a situation, drones may collide with each other, damaging the package they are carrying (e.g., tableware that is easily damaged by impact). Furthermore, due to long congestion, it is conceivable that express packages carried by drones may not arrive within the designated time, or that the freshness of the package (e.g., fresh food) may deteriorate. As such, there is room for consideration of countermeasures to solve various problems caused by drone congestion on delivery routes. In particular, there is room for consideration of a traffic control system that controls the passage of drones depending on the attributes of the package being carried by the drone.

The present disclosure aims to provide a traffic control system that can manage the traffic of drones flying in the sky according to the attributes of the cargo carried by each drone.

A traffic control system according to one aspect of the present disclosure is configured to control the traffic of multiple drones in the sky.
The traffic control system includes:
Acquire a plurality of pieces of aircraft information, each of which is assigned to a corresponding one of the plurality of drones and each of which enables identification of the corresponding one of the plurality of drones, and a plurality of pieces of luggage information, each of which indicates attributes of a corresponding one of a plurality of pieces of luggage carried by the plurality of drones;
Based on the plurality of aircraft information and the plurality of baggage information, a first drone having the highest traffic priority among the plurality of drones is determined;
A passage permission signal permitting passage in the air and aircraft information of the first drone are transmitted to the outside.

According to the above configuration, the first drone with the highest priority is determined based on multiple pieces of aircraft information and multiple pieces of baggage information, and then a passage permission signal and the aircraft information of the first drone are transmitted to the outside. In this way, it is possible to provide a traffic control system that can control the traffic of each drone flying in the sky according to the attributes of the baggage carried by each drone.

At least some of the elements constituting the traffic control system may be provided in a traffic infrastructure facility.
The traffic infrastructure facility may be a traffic light or a street light.

According to the above configuration, at least some of the components of the traffic control system that controls the passage of drones are provided in existing traffic infrastructure facilities such as traffic lights and street lights. In this way, existing traffic infrastructure facilities can be effectively used as locations for installing the components of the traffic control system.

Moreover, the traffic control system includes:
The multiple aircraft information and the multiple pieces of luggage information may be acquired by receiving the multiple aircraft information and the multiple pieces of luggage information from the multiple drones.

According to the above configuration, the traffic control system receives multiple pieces of aircraft information and multiple pieces of baggage information from multiple drones, so this information can be acquired more reliably than when the information is acquired using a camera or the like installed in the traffic control system.

The traffic control system may also acquire the plurality of pieces of aircraft information and the plurality of pieces of luggage information based on a plurality of pieces of image data, each of which indicates a corresponding one of the plurality of pieces of luggage.

According to the above configuration, the traffic control system can acquire multiple pieces of aircraft information and multiple pieces of baggage information based on image data from a camera installed in the traffic control system, without receiving multiple pieces of aircraft information and multiple pieces of baggage information from multiple drones.

Moreover, the traffic control system includes:
determining a second drone having a second highest traffic priority among the plurality of drones based on the plurality of aircraft information and the plurality of baggage information;
The passage permission signal and aircraft information of the second drone may be transmitted to the outside after a predetermined period of time has elapsed since the first drone passed over the transportation infrastructure facility.

According to the above configuration, after a predetermined period of time has elapsed since the first drone passed over the transportation infrastructure facility, the second drone, which has the second highest traffic priority, is permitted to pass over the transportation infrastructure facility. In this way, it is possible to provide a traffic control system that can control the traffic of each drone flying in the sky according to the attributes of the package delivered by each drone.

A traffic control system according to one aspect of the present disclosure is configured to control the traffic of multiple drones in the sky.
The traffic control system includes:
Acquire a plurality of pieces of aircraft information, each of which is assigned to a corresponding one of the plurality of drones and each of which enables identification of the corresponding one of the plurality of drones, and a plurality of pieces of luggage information, each of which indicates attributes of a corresponding one of a plurality of pieces of luggage carried by the plurality of drones;
Determine a traffic priority order for the plurality of drones based on the plurality of aircraft information and the plurality of baggage information;
Information regarding the traffic priority of the multiple drones is transmitted to the outside.

According to the above configuration, the traffic priority of multiple drones is determined based on multiple aircraft information and multiple baggage information, and the information regarding the traffic priority is then transmitted to the outside. In this way, it is possible to provide a traffic control system that can regulate the traffic of each drone flying in the sky according to the attributes of the baggage carried by each drone.

The present disclosure provides a traffic control system that can control the traffic of drones flying in the sky according to the attributes of the cargo carried by each drone.

The following describes an embodiment of the present disclosure (hereinafter simply referred to as "the present embodiment") with reference to the drawings. For the sake of convenience, the dimensions of each component shown in the drawings may differ from the actual dimensions of each component.

First, the traffic control system 1 and drones 2a to 2c according to this embodiment will be described below with reference to Figs. 1 to 3.

Fig. 2 is a block diagram showing an example of the configuration of the traffic control system 1. Fig. 3 is a block diagram showing an example of the configuration of drone 2a.

As shown in FIG. 1, the traffic control system 1 is provided in a street light 40, and is a system for controlling the passage of multiple drones in the sky. In this embodiment, all of the elements that make up the traffic control system 1 are provided in the street light 40, but some of the elements of the traffic control system 1 may be provided in a location away from the street light 40.

The drones 2a to 2c in the sky are located, for example, at a height of 5 to 10 meters above the road surface. Furthermore, on sidewalks and arcades where pedestrians pass by, it is preferable that the drones 2a to 2c are located 2 to 5 meters above the heads of pedestrians.

As shown in Figures 1 and 2, the traffic control system 1 includes a control unit 12, a camera 13, a wireless communication module 14, and a wired communication module 15.

For example, the surrounding environment identification program is a program (trained model) constructed by machine learning using a neural network such as deep learning. Furthermore, the ROM may store a traffic priority table (described below) that associates the type of cargo carried by the drone with the traffic priority of the drone.

The camera 13 is configured to acquire image data showing the surrounding environment of the street light 40. The camera 13 is configured, for example, of a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The wireless communication module 14 may be wirelessly connected to the drone 2 for communication. The wireless communication module 14 includes a high-frequency circuit, a transmitting/receiving antenna, and a signal processing circuit. The wireless communication module 14 may communicatively connect the passage control system 1 to an external device (drones 2a to 2c in this example) based on a wireless communication standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or LPWA. In this embodiment, the passage control system 1 is capable of receiving aircraft information and baggage information from each drone via the wireless communication module 14 and transmitting a passage permission signal or a standby signal to each drone. The wired communication module 15 has a terminal into which a communication cable such as a LAN cable is inserted. The traffic control system 1 may be communicatively connected to an external server located on an IP (Internet Protocol) network such as the Internet via a wired communication module 15.

Next, drones 2a to 2c will be described below. Hereinafter, for ease of explanation, drones 2a to 2c may be collectively referred to as drone 2. Drone 2, which is an unmanned aerial vehicle, is configured to fly in the air in a remote control mode or an autonomous driving mode (automatic driving mode). Drone 2 is used, for example, in a luggage delivery service and transports luggage. Drone 2a transports luggage 3a. Drone 2b transports luggage 3b. Drone 2c transports luggage 3c. Hereinafter, luggage 3a to 3c may be collectively referred to as luggage 3.

The drone 2 is configured to broadcast aircraft information that enables the drone 2 to be identified and baggage information that indicates the attributes of the baggage 3 to the outside while flying in the air. The drone 2 may also be wirelessly connected to a wireless base station (not shown). In this regard, the drone 2 may be equipped with a SIM card for data communication and may be communicatively connected to the wireless base station through a fourth or fifth generation mobile communication system. The drone 2 may be communicatively connected to an external server on an IP network via the wireless base station.

The configuration of drone 2a will be described below with reference to FIG. 3. Drones 2b and 2c are assumed to have the same configuration as drone 2a. As shown in FIG. 3, drone 2a includes a control unit 20, a wireless communication module 21, a camera 22, a GPS (Global Positioning System) 23, and a storage device 24. Drone 2a further includes a sensor 25, a battery 26, a motor 27, and a motor driver 28.

The control unit 20 is configured to control each component provided in the drone 2a. The control unit 20 includes, for example, a computer system including one or more processors and one or more memories, and an electronic circuit configured of active elements such as transistors and passive elements. The processor includes, for example, at least one of a CPU, an MPU, and a GPU. The memory includes a ROM and a RAM.

The wireless communication module 21 has a high-frequency circuit, a transmitting/receiving antenna, and a signal processing circuit. The wireless communication module 21 may communicatively connect the drone 2a to an external device based on a wireless communication standard such as Wi-Fi, Bluetooth, ZigBee, or LPWA. In this embodiment, the drone 2a broadcasts aircraft information and baggage information to the outside via the wireless communication module 21. The wireless communication module 21 may also communicatively connect the drone 2a to a wireless base station via a fourth-generation or fifth-generation mobile communication system.

The camera 22 is configured to acquire image data showing the surrounding environment of the drone 2. The camera 22 is configured, for example, with a CCD or CMOS. The GPS 23 is configured to acquire current location information showing the current location coordinates of the drone 2. The storage device 24 is an external storage device such as a hard disk drive (HDD) or a solid state drive (SSD). Various data such as image data may be stored in the storage device 24.

The sensor 25 may have at least one of an acceleration sensor, a speed sensor, and a gyro sensor. For example, the sensor 25 is configured to detect the flight speed and flight attitude of the drone 2a. The battery 26 is configured to supply power to each component of the drone 2a. The motor 27 functions as a drive source for the drone 2a and is configured to rotate multiple propellers, which are the flight mechanism of the drone 2a. The motor driver 28 is configured to control the drive of the motor 27 based on a flight control signal transmitted from the control unit 20.

Next, an example of a traffic control method for controlling the passage of drones 2a to 2c will be described below with reference to FIG. 4. FIG. 4 is a sequence diagram for explaining an example of a traffic control method for controlling the passage of drones 2a to 2c.

As shown in FIG. 4, in step S1, the control unit 12 of the traffic control system 1 acquires image data showing the surrounding environment of the street light 40 from the camera 13. Next, the control unit 12 detects the drones 2a to 2c flying near the street light 40 based on the acquired image data and the surrounding environment identification program stored in the memory.

Next, in step S2, the drone 2a broadcasts to the outside the drone 2a's aircraft information and the baggage information indicating the attributes of the baggage 3a transported by the drone 2a. Here, the drone 2a's aircraft information is information that is assigned to the drone 2a and enables the drone 2a to be identified. For example, the drone 2a's aircraft information may be an identification number unique to the drone 2a assigned by an administrative agency. Furthermore, the "baggage information" may include type information indicating the type of baggage to be delivered, such as clothing, tableware, food, daily necessities, sporting goods, etc., and delivery priority information indicating the delivery priority of the baggage, such as baggage for normal delivery or baggage for express delivery. In this example, the baggage information indicating the attributes of the baggage 3a includes type information indicating sporting goods and delivery priority information indicating baggage for express delivery. The drone 2a broadcasts the drone information and the baggage information to the outside at a predetermined time interval.

Next, in step S3, drone 2b broadcasts to the outside the aircraft information of drone 2b and the luggage information indicating the attributes of luggage 3b transported by drone 2b. Here, the aircraft information of drone 2b is information that is assigned to drone 2b and enables drone 2b to be identified. For example, the aircraft information of drone 2b may be an identification number unique to drone 2b assigned by an administrative agency. In this example, the luggage information indicating the attributes of luggage 3b includes type information indicating food and delivery priority information indicating luggage for regular delivery. Drone 2b broadcasts the aircraft information and luggage information to the outside at a predetermined time interval.

Next, in step S4, the drone 2c broadcasts to the outside the aircraft information of the drone 2c and the luggage information indicating the attributes of the luggage 3c transported by the drone 2c. Here, the aircraft information of the drone 2c is information that is assigned to the drone 2c and enables the drone 2c to be identified. For example, the aircraft information of the drone 2c may be an identification number unique to the drone 2c assigned by an administrative agency. In this example, the luggage information indicating the attributes of the luggage 3c includes type information indicating clothing and delivery priority information indicating luggage for normal delivery. The drone 2c broadcasts the aircraft information and luggage information to the outside at a predetermined time interval. Note that the order of steps S2 to S4 is not particularly limited, and the processes of steps S2 to S4 may be executed simultaneously.

Next, in step S5, the control unit 12 acquires the aircraft information and baggage information of each of the drones 2a to 2c by receiving the aircraft information and baggage information from each of the drones 2a to 2c via the wireless communication module 14. After that, the control unit 12 determines the passage priority of each of the drones 2a to 2c based on the aircraft information and baggage information of each of the drones 2a to 2c (step S6).

Specifically, the control unit 12 determines the traffic priority of each of the drones 2a to 2c based on the aircraft information and baggage information of each of the drones 2a to 2c by referring to a traffic priority table stored in the memory in which the type of baggage carried by the drone 2 is associated with the traffic priority of the drone 2. An example of the traffic priority table is shown below. Furthermore, regardless of the type of baggage, the traffic priority of a drone carrying baggage for express delivery is higher than the traffic priority of a drone carrying baggage for regular delivery.

In this example, the luggage information of the luggage 3a includes delivery priority information indicating a luggage for express delivery, while the luggage information of the luggage 3b and 3c includes delivery priority information indicating a luggage for normal delivery. Therefore, the drone 2a carrying the luggage 3a has the highest traffic priority among the drones 2a to 2c, and therefore the control unit 12 determines the drone 2a as the drone with the highest traffic priority. Meanwhile, the type of the luggage 3b is food, which has the first traffic priority. Meanwhile, the type of the luggage 3c is clothing, which has the fifth traffic priority. Therefore, the traffic priority of the drone 2b carrying the luggage 3b is higher than the traffic priority of the drone 2c carrying the luggage 3c, and therefore the control unit 12 determines the drone 2b as the drone with the second highest traffic priority, while determining the drone 2c as the drone with the lowest priority. In this way, the control unit 12 determines the traffic priority of each of the drones 2a to 2c after determining the priority of each of the luggage 3a to 3c.

Then, the control unit 12 broadcasts to the outside the aircraft information of the drone 2a together with a passage permission signal that allows passage above the street light 40 (step S7). The control unit 12 also broadcasts to the outside the aircraft information of the drone 2b together with a standby signal that instructs it to wait above the street light 40 (step S8). The control unit 12 also broadcasts to the outside the aircraft information of the drone 2c together with the standby signal (step S9).

In step S10, drone 2a recognizes that it is permitted to pass above the street light 40 in response to receiving the passage permission signal and the aircraft information of drone 2a, and then passes above the street light 40. Furthermore, drone 2b recognizes that it needs to wait above the street light 40 in response to receiving the standby signal and the aircraft information of drone 2b, and then waits above the street light 40. Similarly, drone 2c recognizes that it needs to wait above the street light 40 in response to receiving the standby signal and the aircraft information of drone 2c, and then waits above the street light 40.

Next, the control unit 12 determines that a predetermined period of time has elapsed since the drone 2a passed over the street light 40 (step S11). After that, the control unit 12 broadcasts the aircraft information of the drone 2b together with a passage permission signal to the outside (step S12). In step S13, in response to receiving the passage permission signal and the aircraft information of the drone 2b, the drone 2b recognizes that it is permitted to pass over the street light 40, and then passes over the street light 40.

Next, the control unit 12 determines that a predetermined period of time has elapsed since the drone 2b passed over the street light 40 (step S14). After that, the control unit 12 broadcasts the aircraft information of the drone 2c together with a passage permission signal to the outside (step S15). In step S16, in response to receiving the passage permission signal and the aircraft information of the drone 2c, the drone 2c recognizes that it is permitted to pass over the street light 40, and then passes over the street light 40.

In this way, when multiple drones 2 are present near a street light 40, the traffic control system 1 controls the traffic of each drone 2 according to the attributes of the cargo carried by each drone 2.

According to this embodiment, the drone 2a with the highest priority is determined based on the aircraft information and baggage information of the drones 2a to 2c, and then the passage permission signal and the aircraft information of the drone 2a are broadcast to the outside. Furthermore, after a predetermined period of time has passed since the drone 2a passed over the street light 40, the passage permission signal and the aircraft information of the drone 2b are broadcast to the outside. Next, after a predetermined period of time has passed since the drone 2c passed over the street light 40, the passage permission signal and the aircraft information of the drone 2c are broadcast to the outside. In this way, it is possible to provide a traffic control system 1 that can control the traffic of the drones 2a to 2c flying over the street light 40 in accordance with the attributes of the baggage 3a to 3c carried by each of the drones 2a to 2c.

In addition, in this embodiment, each component that constitutes the traffic control system 1 is provided in a street light 40. In this way, the existing street light 40 can be effectively used as a place to install the components of the traffic control system 1.

In addition, in this embodiment, the traffic control system 1 receives aircraft information and baggage information from the drones 2a to 2c, so this information can be acquired more reliably than when the information is acquired using the camera 13 provided in the traffic control system 1.

In this embodiment, instead of each drone 2a to 2c broadcasting its aircraft information and baggage information to the outside, the aircraft information and baggage information of each drone 2a to 2c may be acquired through the camera 13 of the traffic control system 1. For example, when the camera 13 acquires image data showing the baggage 3a, the control unit 12 may acquire the aircraft information and baggage information of the drone 2a based on the acquired image data. In this regard, a two-dimensional barcode (e.g., a QR code (registered trademark)) showing the aircraft information of the drone 2a and the baggage information of the baggage 3a may be displayed on the baggage 3a or the outer surface of the baggage 3a. The control unit 12 may acquire the aircraft information and baggage information of the drone 2a based on the image data showing the two-dimensional barcode.

Similarly, when the camera 13 acquires image data showing the luggage 3b, the control unit 12 may acquire the aircraft information of the drone 2b and the luggage information based on the acquired image data. In this regard, a two-dimensional barcode showing the aircraft information of the drone 2b and the luggage information of the luggage 3b may be displayed on the outer surface of the luggage 3b. The control unit 12 may acquire the aircraft information of the drone 2b and the luggage information based on the image data showing the two-dimensional barcode.

In addition, when the camera 13 acquires image data showing the luggage 3c, the control unit 12 may acquire aircraft information of the drone 2c and luggage information based on the acquired image data. In this regard, a two-dimensional barcode showing the aircraft information of the drone 2c and the luggage information of the luggage 3c may be displayed on the outer surface of the luggage 3c. The control unit 12 may acquire aircraft information of the drone 2c and luggage information based on image data showing the two-dimensional barcode.

Next, another example of a traffic control method for controlling the passage of drones 2a to 2c will be described below with reference to FIG. 5. FIG. 5 is a sequence diagram for explaining another example of a traffic control method for controlling the passage of drones 2a to 2c.

As shown in FIG. 5, in step S21, the control unit 12 acquires image data showing the surrounding environment of the street light 40 from the camera 13. Next, the control unit 12 detects the drones 2a to 2c flying near the street light 40 based on the acquired image data and the surrounding environment identification program stored in the memory.

In step S22, drone 2a broadcasts to the outside the aircraft information of drone 2a and the luggage information indicating the attributes of luggage 3a. In step S23, drone 2b broadcasts to the outside the aircraft information of drone 2b and the luggage information indicating the attributes of luggage 3b. In step S24, drone 2c broadcasts to the outside the aircraft information of drone 2c and the luggage information indicating the attributes of luggage 3c.

Next, in step S25, the control unit 12 acquires the aircraft information and baggage information of each of the drones 2a to 2c by receiving the aircraft information and baggage information from each of the drones 2a to 2c via the wireless communication module 14. The control unit 12 then determines the traffic priority of each of the drones 2a to 2c based on the aircraft information and baggage information of each of the drones 2a to 2c by referring to the traffic priority table shown in Table 1 (step S26).

Next, the control unit 12 broadcasts information regarding the traffic priority of each of the drones 2a to 2c to the outside (step S27). Here, the information regarding the traffic priority indicates that the traffic priority of drone 2a is first, the traffic priority of drone 2b is second, and the traffic priority of drone 2c is third.

In step S28, drone 2a, in response to receiving the information regarding traffic priority, recognizes that drone 2a has the first traffic priority, and then passes over the street light 40. Furthermore, drone 2b, in response to receiving the information regarding traffic priority, recognizes that drone 2b has the second traffic priority, and then waits in the air above the street light 40. Similarly, drone 2c, in response to receiving the information regarding traffic priority, recognizes that drone 2c has the third traffic priority, and then waits in the air above the street light 40.

In step S29, drone 2b passes over the street light 40 after determining that a predetermined period of time has elapsed since drone 2a passed over the street light 40 (step S30). Next, in step S31, drone 2b passes over the street light 40 after determining that a predetermined period of time has elapsed since drone 2b passed over the street light 40 (step S32).

In this way, when multiple drones 2 are present near a street light 40, the traffic control system 1 controls the traffic of each drone 2 according to the attributes of the cargo 3 carried by each drone 2.

According to the traffic control method of this example, information regarding the traffic priority of each drone 2a-2c is determined based on the drones' aircraft information and baggage information, and the information regarding the traffic priority is then broadcast to the outside. Each drone 2a-2c passes over a street light 40 or waits over a street light 40 based on the received information regarding the traffic priority. In this way, it is possible to provide a traffic control system 1 that is capable of controlling traffic of each drone 2a-2c flying over a street light 40 in accordance with the attributes of the baggage 3a-3c being carried by the drones 2a-2c.

Although an embodiment of the present invention has been described above, it goes without saying that the technical scope of the present invention should not be interpreted as being limited by the description of this embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications of the embodiment are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and its equivalents.

For example, in this embodiment, the traffic control system 1 is provided in a street light 40, which is an example of a traffic infrastructure facility, but this embodiment is not limited to this. For example, the traffic control system 1 may be provided in a traffic infrastructure facility such as a traffic light. Also, in this embodiment, the process of determining the traffic priority of each drone (the process executed in steps S6 and S26) is executed by the control unit 12, but this process may be executed by an external server on an IP network communicatively connected to the traffic control system 1. In this case, the external server determines the traffic priority of each drone and transmits information regarding the traffic priority to the traffic control system 1. The traffic control system 1 then broadcasts a passage permission signal and aircraft information to the outside based on the information regarding the traffic priority received from the external server.
