Abstract

A passenger position tracking device 10 stores a destination floor registered with a lobby destination floor registration device 3 in an elevator lobby 1 and the feature of an image of a passenger photographed by a lobby camera 4 in relation to each other. As the passenger gets on an elevator car 2, the feature of the passenger photographed by an in-car camera 6 and the feature of the image photographed by the lobby camera 4 are collated. If the features coincide, the passenger in the car and the destination floor are related to each other. Using the in-car camera 6, the passenger position tracking device 10 tracks the position of the passenger in the car on the real-time base. As the elevator car 2 is to stop at a destination floor, the passenger position tracking device 10 determines whether a passenger being to get off at this floor is present in the rear part or front part of the car. If the passenger is present in the rear part, an announcement is made to notify that a passenger in the rear part is to get off.

  Next, an operation example of the passenger position tracking device 10 according to the present embodiment will be described with reference to the flowcharts of FIGS.

When a passenger appears in the elevator hall 1 and a destination is registered in the hall destination floor registration device 3 (YES in S101), the hall camera 4 captures the passenger who registers the destination floor, and the first information input unit 21 inputs video information, and the passenger feature extraction unit 13 at the hall obtains the characteristics of the passenger from the video information (S102).
At the same time, the destination floor information indicating the destination floor registered by the landing destination floor registration device 3 is input from the first information input unit 21, and the passenger / floor information creation unit 17 determines the characteristics of the passenger and the destination floor. The passenger information database 18 stores the link information (S103).
Then, when the elevator car arrives at the floor where the passenger is waiting and the passenger enters the elevator car, the in-car camera 6 captures the passenger and the passenger tracking unit 16 enters the passenger car. The passenger tracking unit 16 detects that the passenger has entered the car to the passenger characteristic extracting unit 15 and the passenger / floor information creating unit 17 of the car (S104), and extracts the passenger characteristic of the car. The part 15 obtains the characteristics of the passenger (S105).
Thereafter, the passenger / floor information creation unit 17 compares the passenger characteristics obtained in the car (for example, facial characteristics) with the passenger characteristics obtained at the landing (for example, facial characteristics) and detects them in the car. If the passenger characteristics coincided with the passenger characteristics detected at the landing (YES in S106), the passenger's destination floor stored linked to the passenger detected at the landing was detected in the car. Passenger / floor information is generated so as to be linked with the passenger, and the passenger information database 18 stores the generated passenger / floor information (S108).
In addition, as shown in the flowchart of FIG. 17 to be described later, a passenger ID is assigned to each passenger by the passenger tracking unit 16, and the passenger ID and the passenger's location information are sent from the passenger tracking unit 16 to the passenger / floor information creation unit 17. Therefore, in the passenger / floor information, the passenger's location and the destination floor are associated with the passenger ID.
On the other hand, if the characteristics of the passenger detected in the car do not match the characteristics of the passenger detected at the landing (including the case where no passenger is detected at the landing) (NO in S106), the passenger / floor information creation unit 17 determines whether or not the destination floor is registered in the car based on whether or not the destination floor information is input from the car operation panel 5 (S107). If the destination floor is not registered in the car (NO in S107). ) Returns to S101.
If the destination floor is registered in the car (YES in S107), the passenger / floor information creation unit 17 associates the destination floor registered in the car with the passenger ID and location information. Information is generated and the passenger information database 18 stores the generated passenger / floor information (S108).

After that, for passengers detected in the car, every time the position changes, the passenger tracking unit 16 notifies the passenger / floor information creation unit 17 of a position change notification (S109). The passenger / floor information creation unit 17 changes the position information of the passenger in the passenger / floor information, and the passenger information database 18 changes the passenger / floor information after the change. Is stored (S111). At this time, the passenger / floor information creation unit 17 determines whether the passenger's location corresponds to the rear area in the car, and describes whether the rear area is applicable / not applicable to the passenger / floor information. To do.
In addition, when the passenger tracking unit 16 detects that the passenger has got off (YES in S112), the passenger / floor information creation unit 17 is notified of the passenger ID of the passenger who got off from the passenger tracking unit 16, and is notified. The passenger ID record is deleted from the passenger / floor information (S113).
If the destination floor is registered in the car (YES in S114), the passenger / floor information creation unit 17 changes the passenger's passenger / floor information, and the passenger information database 18 changes the passenger. Store floor information (S115).
If there are other passengers (YES in S116), the process returns to S109.

  Next, an operation example of the passenger tracking unit 16 according to the present embodiment will be described with reference to FIG.

The passenger tracking part 16 analyzes the image | video image | photographed with the camera 6 in a car, and detects the change of a passenger area (S301).
The passenger tracking unit 16 determines that a change has occurred in the passenger area when, for example, a new passenger enters a certain floor, when the passenger gets off, or when a passenger on board moves in the car.
If a new passenger appears at the car entrance and a passenger area appears (YES in S302), the passenger tracking unit 16 notifies the passenger feature extraction unit 15 of the car of the new passenger (S303) Passenger ID is allocated to the appearing passenger area (S304).
Next, the passenger tracking unit 16 notifies the passenger ID and location information to the passenger / floor information creation unit 17 (S305).
As described above, in response to the notification (S303) from the passenger tracking unit 16 to the passenger characteristic extracting unit 15 of the car, the passenger characteristic extracting unit 15 of the car obtains the characteristics of the passenger (S105).
Further, based on the notification (S305) from the passenger tracking unit 16 to the passenger / floor information creation unit 17, the passenger / floor information creation unit 17 associates the location and destination floor with the passenger ID. The floor information is generated, and the passenger / floor information generated by the passenger information database 18 is stored (S108).

On the other hand, when a new passenger does not appear at the car entrance (NO in S302), the passenger tracking unit 16 moves when the passenger moves out of the car, that is, when the passenger gets off and the passenger area disappears (S306). YES), the passenger ID and the information that the passenger has got off are notified to the passenger / floor information creation unit 17 (S307).
When the passenger moves in the car (NO in S306), the passenger ID and the location of the passenger's destination are notified to the passenger / floor information creation unit 17 (S308).
As described above, the passenger / floor information creation unit 17 is notified of the passenger ID of the passenger who got off from the passenger tracking unit 16 by the notification of S307, and deletes the record of the notified passenger ID from the passenger / floor information. (S113).
Moreover, the passenger / floor information creation unit 17 changes the position information of the passenger in the passenger / floor information by the notification in S308, and the passenger information database 18 stores the changed passenger / floor information (S111). ).

  Next, an example of updating passenger / floor information will be described with reference to FIGS.

4, 6, 8, and 10 show the movement of passengers.
5, FIG. 7, FIG. 9, and FIG. 11 are examples of passenger / floor information showing the situation in the car of FIG. 4, FIG. 6, FIG. 8, and FIG.
As described above, it is possible to determine where the passenger is by providing grid coordinates in the elevator car as shown in FIG.
Also, how far within the car is “rear” in the car is defined by a parameter or the like.
In the present embodiment, an example will be described in which a coordinate system as shown in FIG. 4 is provided and 4A-4E and 5A-5E are defined as “rearward”.

For example, as shown in FIG. 4, when the passenger 1 (23) registers the third floor as the destination floor using the landing destination floor registration device 3 of the hall 1, the passenger / floor information creation unit 17 sets the destination floor information and the landing camera. The feature extracted by the passenger feature extraction unit 13 at the hall is acquired from the video of No. 4, and information obtained by linking the destination floor and the feature is registered in the passenger information database 18.
When passenger 1 (23) registered on the third floor at landing 1 enters the car, the features extracted by the passenger feature extraction unit 15 from the car camera 6 and the footage camera 4 video The passenger / floor information creation unit 17 determines that the passenger is a passenger who has registered the third floor as a destination floor by comparison with the features extracted by the passenger feature extraction unit 13 of the hall. For example, a passenger ID such as 1 is allocated to the passenger, and the passenger / floor information creation unit 17 generates a record of passenger / floor information in which the registered floor is associated with the passenger ID, and the generated record is used as the passenger information. Register in the database 18.
In addition, when the passenger 1 (23) moves to the position of the coordinate 5A after getting on, the passenger / floor information creation unit 17 stores the passenger / floor information of the passenger 1 (24) stored in the passenger information database 18. Coordinate 5A is described in the coordinate field of the record, and at the same time, it is determined whether or not the coordinate 5A is “rear”. Record 25 in FIG.

Next, as shown in FIG. 6, when passenger 2 (26) enters the car, even if passenger 2 (26) has already registered the floor at the landing, the car operation panel in the car When the destination floor is to be registered again at 5, the passenger 2 (26) moves to the position of the coordinate IE and operates the car operation panel 5.
When the destination floor is registered on the car operation panel 5, the passenger / floor information creation unit 17 uses the passenger 2 (27) at the position of the coordinate IE in the vicinity of the car operation panel 5 and the car operation panel 5 at that time. The passenger / floor information is updated by relinking the registered floor and the updated passenger / floor information is registered in the passenger information database 18.
After that, the passenger tracking unit 16 tracks the passenger 2 (27), the passenger / floor information creation unit 17 registers the coordinates at which the passenger is located in the passenger information database 18, and the passenger 2 (28) has the coordinate 5E. When it is in the position, it is determined that it is “rear” and is registered in the passenger information database 18 (record 29 in FIG. 7).

  Next, as shown in FIG. 8, when the passenger 3 (30) whose destination is registered on the fourth floor enters the car, when the passenger 3 (30) moves to the position of the coordinate 2A, the passenger 3 Regarding the passenger / floor information of (31), since the position of the coordinate 2A is not “rear”, the rear determination is “not applicable” (record 32 in FIG. 9).

  Further, as shown in FIG. 10, when the passenger 1 (33) who has already been determined to be “rear” because he / she is already at the position of the coordinate 5A moves to the position of the coordinate 3C, the position of the passenger 1 (34) is “ Since it is no longer “backward”, the passenger / floor information of passenger 1 (34) is registered with the coordinate column changed to coordinate 3C and the rearward determination is also “not applicable” (record 35 in FIG. 11). ).

  In this way, when the passenger is generated in the car, when the passenger moves in the car, or when the destination floor is registered on the operation panel in the car, the passenger / floor information creating unit 17 Passenger / floor information is updated sequentially.

Next, an operation example of the notification determination unit 20 will be described with reference to FIG.
For example, when the passenger arrangement in the car is as shown in FIG. 12 and the passenger information database 18 stores the passenger / floor information shown in FIG. For example, it is determined whether or not the vehicle stops on the fifth floor (S201), and there are passengers whose destination floor is the fifth floor as shown in the record 36 and the record 37. Therefore, the elevator car 2 is stopped on the fifth floor. (YES in S201).
Next, the congestion state determination unit 19 determines whether the car is congested or not based on the video taken by the car camera 6 and the weight information from the scale device 11 (S202).
This criterion can be changed by a parameter. For example, when the number of passengers recognized by the in-car camera 6 exceeds 50% of the number of passengers, it is “congested”, and the weight of the scale device 11 is a certain threshold value. It is defined as “congested” when exceeding.
When the determination in the congestion status determination unit 19 is “congested”, the notification determination unit 20 determines whether there is a passenger who is “corresponding” in the rear determination of passenger / floor information on the fifth floor, which is the next stop floor. Is determined (S203).
As a result of the determination, if there is a passenger who becomes “corresponding” (YES in S203), there is a passenger getting off behind, so the notification determination unit 20 gives an announcement of the content prompting the passenger to leave the road to the announcement device 7 An alarm is issued (S204).
In addition, the notification determination unit 20 causes the information display 8 in the car to simultaneously display a message, a picture, or the like having the same content (S205).
