Hereinafter, a work progress estimation device and a work progress estimation method according to an embodiment will be described in detail based on the drawings.

Embodiment 1.
FIG. 1 is an example of a configuration diagram of the work progress estimation device 3 according to the first embodiment. The work progress estimation device 3 includes an acquisition section 31 , an estimation section 32 , a determination section 33 , and a notification section 34 . The work progress estimating device 3 is operated, for example, by a business operator that operates turnaround operations at an airport.

The acquisition unit 31 acquires the flight information of the aircraft A1 stored in the storage device 1 and the video IM captured by the imaging device 2. The storage device 1 is operated by, for example, an airport operator. An airport operator records the latest flight information in the storage device 1. Alternatively, the airline company may record the latest flight information in the recording device 1. The imaging device 2 is, for example, a camera installed on the tarmac of an airport, and captures a video IM including the tarmac. The flight information includes at least information regarding the aircraft A1 within the parking lot. Flight information and video IM will be explained in detail later using FIGS. 2 and 3.

The estimating unit 32 estimates work progress information indicating the progress of work on the apron based on the flight information of the aircraft A1 on the apron and the video IM. Specifically, the estimation unit 32 estimates the type of work in the parking lot and the start time of the work by image recognition of the video IM. The estimation unit 32 estimates the time required to perform each task based on the flight information. The estimation unit 32 estimates the scheduled end time of the work based on the start time of the work and the time required to perform the work, and estimates the progress of the work.

The determination unit 33 determines whether or not the work is delayed based on the work progress information. Specifically, the determination unit 33 determines whether or not the work is delayed based on whether the scheduled end time of the work in the work progress information is past the scheduled departure time (or a predetermined time before the scheduled departure time). Determine.

The notification unit 34 outputs the work progress information estimated by the estimation unit 32 and the determination result determined by the determination unit 33. The notification unit 34 outputs the work progress information and the determination result to a display device (not shown) such as a monitor.

The notification unit 34 is a device (not shown) operated by a business that operates airport turnaround operations, and outputs work progress information and determination results to a device different from the work progress estimation device 3. It's okay. As an example, the device determines whether or not it is necessary to change the originally planned work plan based on the work progress information and the determination result, and if it is determined that the work plan needs to be changed, , change the work plan.

The notification unit 34 may output work progress information and determination results to air traffic control. As an example, air traffic control determines the order of runway use based on work progress information and determination results. Specifically, air traffic control instructs aircraft A1, which is stopped at a parking lot where work delays are not occurring, to take off first, and aircraft A1, which is stopped at a parking lot where work delays are occurring, to take off later. put out.

The notification unit 34 may output the work progress information and the determination result to a device (not shown) operated by the airport operator. As an example, the device determines the apron to be allocated to the subsequent aircraft A1 based on the work progress information and the determination result. Specifically, the device allocates the subsequent aircraft A1 to the apron where no work delay has occurred, and does not allocate the subsequent aircraft A1 to the apron where the work delay has occurred.

Note that the notification unit 34 may output either the work progress information or the determination result.

The storage device 1 and the work progress estimation device 3 are connected to a network. The storage device 1 and the work progress estimation device 3 exchange information with each other via a network. In the first embodiment, the network is, for example, a WAN (Wide Area Network) such as the Internet, but it may also be a LAN (Local Area Network).

FIG. 2 is an example of flight information stored in the storage device 1 according to the first embodiment. Flight information includes the apron number, aircraft number, work type, departure point, destination, scheduled arrival time, scheduled departure time, number of disembarkations, number of boarders, amount of unloading, This includes the amount of cargo loaded.

The parking lot number is a number indicating the location where the aircraft A1 is parked. The aircraft number is a number that uniquely indicates the parked aircraft A1. The work type is a work ID set for the parked aircraft A1. The departure point is information indicating from which airport the aircraft A1 corresponding to the aircraft number came. The destination is information indicating the destination of the aircraft A1 corresponding to the aircraft number. The scheduled arrival time is the scheduled time of arrival at the airport where the work is to be performed. The scheduled departure time is the scheduled time of departure from the airport where the work is to be performed. The number of passengers disembarking is the number of passengers P2 disembarking at the airport where the work is to be performed. The number of passengers boarding is the number of passengers P2 boarding at the airport where the work is to be performed. The unloading amount is the amount of baggage to be unloaded at the airport where the work is performed. The loading amount is the amount of baggage to be loaded at the airport where the work is to be performed.

In the example shown in FIG. 2, there are two types of work for aircraft A1 (aircraft number "AA1234") in the apron corresponding to apron number 1: "OP003" and "OP005."

In the example shown in FIG. 2, the flight information includes both the number of passengers, which is the number of passengers disembarking and the number of passengers on board, and the amount of luggage, which is the amount of unloading and loading. However, if the amount of luggage checked by passengers is large and the amount of other cargo is small, at least one of the number of passengers and the amount of luggage may be included. This is because the approximate amount of luggage can be estimated from the number of passengers. Similarly, the approximate number of passengers can be estimated from the amount of luggage.

FIG. 3 is an example of a video IM captured by the imaging device 2 according to the first embodiment. In the example shown in FIG. 3, the estimation unit 32 estimates the aircraft A1, the luggage transport vehicle V1, the refueling vehicle V2, the passenger boarding bridge P1, and the passenger P2 passing through the passenger boarding bridge P1 from the video IM. recognize.

FIG. 4 is an example of work progress information estimated by the estimation unit 32 according to the first embodiment. The work progress information includes an apron number, an aircraft number, a work type, a work start time, a work end time, a work progress status, a scheduled departure time, and an update time.

The work start time is the time estimated by the estimation unit 32 based on the video IM. In FIG. 2, for example, it is assumed that the work type "OP003" corresponding to parking lot number 1 is unloading and loading work, and the work type "OP005" is refueling work. The estimation unit 32 recognizes the baggage transport vehicle V1 approaching the aircraft A1 in the image IM shown in FIG. When the estimating unit 32 recognizes that the cargo transport vehicle V1 has stopped in front of the aircraft A1, it determines that the unloading and loading operations have started. As shown in FIG. 4, the estimation unit 32 estimates the unloading and loading work start time to be 13:15. Similarly, the estimation unit 32 recognizes the refueling vehicle V2 approaching the aircraft A1 in the image IM shown in FIG. When the estimating unit 32 recognizes that the refueling vehicle V2 has stopped in front of the aircraft A1, it determines that the refueling operation has started. As shown in FIG. 4, the estimation unit 32 estimates the refueling work start time to be 13:30.

The scheduled work end time is the time estimated by the estimation unit 32 based on flight information. The estimation unit 32 estimates the time required to perform the unloading and loading operations based on the unloading amount and loading amount shown in FIG. 2 . Then, the estimation unit 32 estimates the scheduled end time of the work based on the work start time and the time required to perform the work. As shown in FIG. 4, the estimation unit 32 estimates that the time required to perform the unloading and loading operations is one hour. Then, the estimation unit 32 estimates the scheduled work end time to be 14:15. Similarly, the estimation unit 32 estimates the amount of fuel consumed based on the distance from the departure point shown in FIG. 2 to the airport where the work is to be performed, and estimates the time required to perform the refueling work. Then, the estimation unit 32 estimates the scheduled end time of the work based on the work start time and the time required to perform the work. As shown in FIG. 4, the estimation unit 32 estimates that the time required to perform the refueling operation is 15 minutes. Then, the estimation unit 32 estimates the scheduled work end time to be 13:45.

The work progress status is a visualization of the progress status of each work. Specifically, the work progress status is the progress status at the update time when the work progress information shown in FIG. 4 is updated, expressed as a percentage and a warning mark. For example, the update time of the work progress information for parking lot number 1 is exactly halfway between the work start time and the scheduled end time of the work type "OP003", so the work progress status of the work type "OP003" is 50%. becomes. Since the scheduled end time of the work type "OP003" is past the scheduled departure time of the aircraft A1 with the aircraft number "AA1234", a rain mark is displayed as a warning mark indicating that the work is delayed. Ru. On the other hand, the work progress status of the work type "OP005" is 100%, meaning that it is completed. Therefore, for the work type "OP005", a clear mark indicating that the work is on schedule without any delay is displayed as a warning mark.

In addition, when the work type "OP003" is unloading and loading work, the estimation unit 32 recognizes the cargo moving between the aircraft A1 and the cargo transport vehicle V1, thereby estimating the moving cargo. The number may be estimated. The estimating unit 32 may update the scheduled work end time as appropriate based on the number of items to be moved.

In the example shown in FIG. 4, the determination unit 33 determines that the work is delayed for the work type "OP003", and determines that the work is not delayed for the work type "OP005" and the work type "OP010". do. The notification unit 34 outputs work progress information and the determination result of the determination unit 33.

When the notification unit 34 outputs work progress information and judgment results to a device operated by a business operator operating airport turnaround operations, the device performs work type “OP003” as a changed work plan. Delays in work can be made up for by making plans to increase the number of workers. Note that the estimation unit 32 may update the time required to perform the work in accordance with changes in the work plan.
