Delivery monitoring device, delivery management method, recording medium

1. A delivery monitoring device comprising:

a memory configured to store instructions; and

a processor configured to execute the instructions to:

acquire a tag signal transmitted by a tag signal transmission device, the tag signal transmission device being attached to a package located in a vicinity of the delivery monitoring device;

acquire position information indicating a position of the delivery monitoring device;

receive a signal that indicates opening of a door of a carrier when an amount of light is a prescribed threshold value or higher, the carrier containing the delivery monitoring device; and

cause a transmitter to transmit management information including the tag signal and the position information, to a delivery management server, in response to the signal that indicates the opening of the door of the carrier being received,

wherein acquiring the tag signal comprises acquiring a plurality of tag signals from a plurality of tag transmission devices, each of the plurality of tag signal transmission devices performing transmission with an interval from reception of a reading signal to transmission of the tag signal being changed.

2. The delivery monitoring device according to claim 1 , further comprising:

an antenna that receives the tag signal; and

a changing mechanism that, by changing an orientation of the antenna, changes a direction in which the antenna reads a signal.

3. The delivery monitoring device according to claim 1 ,

wherein the processor is configured to execute the instructions to acquire a tag signal transmitted by a tag signal transmission device attached to a structure containing the package, and

causing the transmitter to transmit the management information comprises causing the transmitter to transmit, as the management information, information including the tag signal transmitted by the tag signal transmission device attached to the package, the tag signal transmitted by the tag signal transmission device attached to the structure, and the position information, to the delivery management server.

4. A delivery management method comprising:

acquiring, by a delivery monitoring device, a tag signal transmitted by a tag signal transmission device, the tag signal transmission device being attached to a package located in a vicinity of the delivery monitoring device;

acquiring, by the delivery monitoring device, position information indicating a position of the delivery monitoring device;

receiving a signal that indicates opening of a door of a carrier when an amount of light is a prescribed threshold value or higher, the carrier containing the delivery monitoring device; and

transmitting, by the delivery monitoring device, management information including the tag signal and the position information, to a delivery management server, in response to the signal that indicates the opening of the door of the carrier being received,

wherein acquiring the tag signal comprises acquiring a plurality of tag signals from a plurality of tag transmission devices, each of the plurality of tag signal transmission devices performing transmission with an interval from reception of a reading signal to transmission of the tag signal being changed.

5. A non-transitory computer-readable recording medium storing a program that causes a computer in a delivery monitoring device to execute:

acquiring a tag signal transmitted by a tag signal transmission device, the tag signal transmission device being attached to a package located in a vicinity of the delivery monitoring device;

acquiring position information indicating a position of the delivery monitoring device; and

receiving a signal that indicates opening of a door of a carrier when an amount of light is a prescribed threshold value or higher, the carrier containing the delivery monitoring device; and

transmitting management information including the tag signal and the position information, to a delivery management server, in response to the signal that indicates the opening of the door of the carrier being received,

wherein acquiring the tag signal comprises acquiring a plurality of tag signals from a plurality of tag transmission devices, each of the plurality of tag signal transmission devices performing transmission with an interval from reception of a reading signal to transmission of the tag signal being changed.

6. The delivery monitoring device according to claim 1 , wherein the delivery monitoring device has a portable form and is loaded on the carrier together with the package.

7. The delivery monitoring device according to claim 1 ,

wherein a tag signal transmission device is attached to a pallet, and

the processor is configured to execute the instructions to acquire a tag signal transmitted by the tag signal transmission device attached to the pallet.

8. The delivery monitoring device according to claim 1 , wherein the processor is configured to execute the instructions to:

detect the light; and

detect that the door has been opened when the amount of the light is the prescribed threshold value or higher.

9. The delivery monitoring device according to claim 1 ,

wherein the carrier is a truck, and

receiving the signal that indicates the opening of the door comprises receiving the signal that indicates the opening of the door from an opening/closing signal transmission device provided on the door of the truck.
