<Data>
The management server 2 according to the present embodiment has a node position information DB regarding the position of each utility pole. As illustrated in FIG. 4, the node position information DB includes at least a node identifier and position coordinates that are uniquely given to each power pole. The position coordinates according to the present embodiment include at least three elements such as latitude, longitude, and height of the utility pole.

<Process flow>
With reference to FIG. 5, a route generation method according to the present embodiment will be described. The system according to the present embodiment takes charge of a transaction (hereinafter referred to as “delivery transaction”) related to delivery of a product purchased by a user using EC or the like. The delivery transaction itself is generated based on, for example, user address information registered in advance.

  When the management server 2 starts the delivery transaction, the utility pole closest to the package shipping source (starting node) and the utility pole closest to the delivery destination (user address, etc.) are specified. In the illustrated example, the start point node is a utility pole a and the end point node is a utility pole j. The management server 2 calculates the shortest path connecting the utility pole a and the utility pole j. At this time, a route capable of avoiding a collision is generated in consideration of the position and route of another unmanned air vehicle 1.

  The collision avoidance may be performed between the unmanned air vehicles 1. For example, a collision may be avoided by changing the height of one unmanned air vehicle and the height of the other unmanned air vehicle.

  Returning to FIG. 5, the route according to the present embodiment proceeds in the order of the utility pole a → the utility pole b → the utility pole d → the utility pole f → the utility pole h → the utility pole j. Note that a part of the route may be detoured in order to avoid the above-described collision avoidance. Fly in a region away from the electric wire by a predetermined distance in the vertical direction (height direction).

  A processing flow of the management server 2 will be described with reference to FIG. In this embodiment, when a delivery transaction (route request) occurs (step S601), node position information is read (step S603). Based on the delivery transaction and the node position information, the management server 2 identifies the start point node, the transit node, and the end point node, and generates a route (step S605). The generated route information is transmitted to the unmanned aerial vehicle 1, and delivery by the flight of the unmanned aerial vehicle 1 is started (step S607).

  With reference to FIG. 7, the flow of the delivery process using the system according to the present embodiment will be described. As shown in the drawing, the delivery process is executed by the management server 2, the unmanned air vehicle 1, and the user terminal.

  When a delivery transaction occurs (SQ701), the management server 2 reads node position information from the node DB (SQ703) and generates a route (SQ705). The management server 2 transmits the generated route information to the unmanned air vehicle (SQ707). The unmanned air vehicle starts flying based on the received route information (SQ709).

  When the unmanned air vehicle arrives at the destination, the destination arrival notification is notified to the management server 2 (SQ711). The management server 2 notifies the arrival notification to the user terminal (SQ713). After confirming the destination of the arrived package, the user transmits a notification of each position to the management server 2 (SQ715). When the management server 2 receives the confirmation notice from the user regarding the package, the management server 2 unlocks the package loaded on the unmanned air vehicle 1 (SQ717). The unlocked package can be received by the user. If necessary, the management server 2 updates the status of the delivery transaction when the delivery is completed (SQ719).

  According to the above processing, as shown in FIG. 8, the unmanned air vehicle 1 moves over the utility pole 20 and the electric wire 30 according to the route generated by loading the package P from the package storage location 100 (for example, a warehouse). , The package P can be delivered to the user's home 200 and delivered to the user.

  In the embodiment described above, as shown in FIG. 9A, a so-called client server model including the unmanned air vehicle 1 and a management server 2 connected via a network is used. However, as shown in FIG. 9B, a peer-to-peer system composed of a plurality of unmanned air vehicles 1 may be used.

<Service anonymization>
At the time of providing the service by the unmanned air vehicle described above, for example, when delivering a package, it is necessary to verify whether the recipient is a valid recipient. In the present embodiment, by applying the block chain technology to the verification, it is possible to perform appropriate delivery while improving anonymity.

  Hereinafter, a transaction in which an unmanned air vehicle (limited to those that can be specified by a unique identifier) delivers a predetermined package to a user having a unique user ID will be described as an example.

  As shown in FIG. 10, in the authentication according to the present embodiment, when a transaction occurs (step S1001), the transaction is broadcast in the network (step S1003), and the transaction is verified (step S1005). When a block related to the verified transaction is generated (S1007), the block is added to the chain.

  As shown in FIG. 11, interaction between the unmanned air vehicle 1 and the management server 2 (for example, acquisition of delivery destination information, lock of luggage to the unmanned air vehicle, etc.), and interaction between the management server 2 and the user 202 The management server 2 requests the blockchain network to verify the legitimacy of these transactions at the time of (such as authentication at the time of receipt of a package or a request to unlock the package), and The history is left in the block as a log.

<Preparation>
More specifically, the recipient user 202 creates his / her public / private key pair. Next, a hash value of the public key is created and provided to the management server 2. The hash value of this public key serves as a user address (destination) as a delivery destination. For example, information on a QR code (registered trademark) including a hash value of the public key may be displayed on the user's terminal. In this state, the user has his / her public key and secret key, and the management server 2 has the public key hash of the user 202.

<Outline of transaction method>
When the unmanned air vehicle 1 delivers a package to the user, information declaring the validity of the package being delivered to the user is shared in the network. More specifically, only a person who has a secret key corresponding to the public key hash that is the destination can receive a package from an unmanned air vehicle. Since only the principal has the private key, only the principal who is the destination can use it.

  Normally, it is recommended to renew the public key pair in units of one transaction (delivery, payment, etc.).

  The specific data structure is as follows. First, FIG. 12 shows the structure of the package information delivered by the management server 2 to the user 202 by the unmanned air vehicle 1. As shown in the figure, the transaction ID (TX_ID), the public key of the package sender (for example, the unmanned air vehicle 1), and the electronic signature information (Signature Script) are the input information. The Inpu information is information for identifying who (from where) the package to be delivered belongs. The output information includes an ID (Del_ID) for specifying a delivery item and public key hash information (Pubkey Script) of the delivery destination (user 202).

  The person who can receive the package for delivery is only the person who has the private key corresponding to the public key of the user 202 (that is, the user 202). In addition, once the user 202 authenticates using the secret key, the output information regarding the package cannot be used and cannot be received twice.

  As described above, in the present embodiment, by including the public key hash information of the destination (person) to whom the package is to be delivered in the information related to the transaction, only the destination can surely receive the package.

  Although the embodiment described above is for delivery purposes, it may be applied to patrol purposes such as security. In this case, the management server 2 has only to generate a cyclic route based on the cyclic route and node position information specified by the user. Further, when the patrol is completed, the patrol transaction may be terminated after the patrol is completed and transmitted to the user and approved by the user.

  The above-described embodiments are merely examples for facilitating understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
