The passenger management table which shows the boarding floor for every user in one embodiment, and a descending floor. FIG. 3 is a table of the number of people getting on and off according to floors in which the vertical axis is a floor and the horizontal axis is a floor according to an embodiment.

Hereinafter, an embodiment of a group management elevator system according to the present invention will be described with reference to the drawings.
FIG. 1 shows a group management elevator system, an elevator control device 1 installed in an elevator machine room or a similar place, and three cars installed in a hoistway and managed by the elevator control device 1. 41, 42, 43, and a hall call device 92 and a hall lantern (also called reservation lights) 94, 95, 96 installed at the service floor hall of each car. The number of cages is three in the figure, but it is two or more, usually about three to eight.
In the cars 41, 42, 43, there are provided destination floor registration devices 51, 52, 53 for elevator users to register destination floors, and monitoring cameras 61, 62, 63 for monitoring the inside of each car. Load sensors 71, 72, 73 are provided on the floor of the car to detect the degree of congestion of the users who have entered the car. The surveillance cameras 61, 62, and 63 have a function of tracking a person from the outside of the screen until entering the screen.

  The hall call information collection unit 21 detects and collects that hall call is generated by operating the hall call device 92 at the service floor of each car. The car information collection unit 22 takes information on destination floors from the destination floor registration devices 51, 52, 53 of each car, loads the passenger sensors from the load sensors 71, 72, 73, and rides each user from the monitoring cameras 61, 62, 63. Collect information that identifies the floor and descending floors. The traffic information collection unit 23 collects information from the hall call information collection unit 21 and the car information collection unit 22 to determine whether the traffic state is congested or quiet. Furthermore, according to the load change of the car by the load sensors 71, 72, 73, the amount of passengers and passengers is measured, and the traffic on the destination floor between the floors is calculated from the relationship with the floor where the car call is not generated. Ask.

  The assigned elevator selection unit 26 is based on the information of the hall call information collection unit 21, the car information collection unit 22, and the traffic information collection unit 23, hall call by the hall call device, and destination floors by the destination floor registration devices 51, 52, 53. The most suitable car is selected as the assigned car for the car call. That is, the group management control device 2 calculates an expected waiting time for a new hall call, and assigns the hall call to the car having the minimum waiting time or the car having the minimum maximum waiting time. In addition, in order to improve the accuracy of the waiting time, the traffic information specific to the building is learned for each floor by the traffic information collecting unit 23, and the probability of stoppage due to the call that has not occurred in the non-passed floor and the car call derived therefrom. Estimate the probability of occurrence and obtain the estimated arrival time. The selected car is moved in response to the hall call or the car call by the machine control device.

  FIG. 2 is an image of a surveillance camera installed in the car, and is a screen that captures the entire area of the car. A101 is a person in the car and A102 is a person who is currently in the car. The surveillance camera 61 and the machine controller 31, the surveillance camera 62 and the machine controller 32, and the surveillance camera 63 and the machine controller 33 exchange data via the image processing device 201.

  When the user enters the screen from the outside of the screen, the image processing apparatus 201 determines and stores that the user has boarded, and stores the position and characteristics in the car with a unique number added. Further, until the boarded user goes out of the screen, a position indicating where the user is on the screen is determined from the stored characteristics. Then, the user is traced until the user goes out of the screen, and when the user goes out of the screen, it is determined that the user has gone down and stored.

  Furthermore, numbers A, B... N unique to each user are added, and the boarding floor and the landing floor are stored for each user as a passenger management table as shown in FIG. The car position data indicating the floor is transmitted from the machine control device 31 to the image processing apparatus 201, and when it is determined that the user has boarded, the car position data is referred to in the column of the floor of the passenger management table with reference to the car position data. Added as car position. In addition, when it is determined that the user has exited, the car position data transmitted from the machine control device 31 at that time is added to the column of the descending floor of the passenger management table, and the car position data transmitted at that time is added to the column of the descending floor of the passenger management table. The boarding / descending floors according to the passenger management table are transmitted to the group management device 2. For example, when a person who has got on the second floor gets off at the fifth floor, the information of the second floor and the fifth floor is sent to the group management control device 2.

  The group management control device 2 includes a table of number of people getting on and off between floors with the vertical axis shown in FIG. 4 as the floor and the horizontal axis as the floor, and the data sent from the monitoring cameras 31, 32, and 33 are received. Based on the number of people getting on and off by floor, the table is updated. When information on boarding floor 2 and landing floor 5 is received, 1 is added to boarding floor 2 and landing floor 5 and added. The number of people getting on and off by floor is divided by a certain period or the total number of people, and the number of people getting on and off by floor is stored as a learning result for each division as a learning result. Therefore, it is possible to accurately understand the number of people getting on and off between floors and the usage status of the elevators by the floor by using the learning table for getting on and off by floor, calculating the arrival time accurately, and improving the performance of group management control. .
