Abstract

PROBLEM TO BE SOLVED: To enable appropriate operation by maintaining the waiting condition or the operating condition if the arrival time of a passenger is within or not less than a specified waiting time when an elevator in the waiting condition is present on a floor, or providing the control to generate a call to the floor when no elevator is present. SOLUTION: When the moving direction 11 of a passer-by 10 in a detected image is toward a door 9 on a hall side so as to enter a car 6, the passer-by is judged to be a passenger 12, and the arrival time at the hall door 9 is calculated by the moving speed of the passenger. If the arrival time is smaller than the waiting time subtracted from the maximum set waiting time of an elevator, the elevator is stopped. If the elevator is not stopped, an elevator control device 4 is instructed to generate a call for the car 6 through a communication line 17. A weight measuring device 7 adds the weight of those 13 in the car to the weight of those 12 to enter the car, and if the total weight is smaller than the load value, the elevator is in the waiting condition. The control is provided in which the completion of the loading is judged, and the release of the waiting is judged when the weight of those in the elevator is added.

An operation example of the elevator operating device will be described with reference to this flowchart.

The image processing camera 15 is fixed to the ceiling in front of the hall-side door 9 in the room 1 and constantly processes the photographed image. The moving body portion in the image is always detected by the image processing, and the result is detected. Transmit to the image processing device 16 (1
01). When a moving object is detected in the image, the image processing device 16 determines that the moving object has entered the room 1, captures the moving object portion as a frame, and determines whether or not the moving object is a person based on the size and shape of the frame. Is determined (102). Here, when it is determined that the moving object is not a person (NO in 103), the processing of steps 101 and 102 is repeated for another moving object. If it is determined that the moving object is a person (YES in 103), it is determined that the person 10 has entered the room 1 from outside.

Next, the image processing unit 16 converts the values of the coordinate positions of the two points on the screen to which the passerby 10 has moved for a predetermined time into the coordinate positions in the room, and the passerby passes in the direction indicated by the straight line connecting the two points. 10 is detected as the traveling direction 11 (104). If the traveling direction 11 is the direction in which the hall side door 9 of the elevator is located, the pedestrian 10 is determined to be the elevator occupant 12 (YES in 105), and If it indicates a direction other than the hall side door 9, it is determined to be the occupant 14, and the processes of steps 101 to 104 are repeated for other moving objects (1
05 and NO).

[0013] After determining the person 12 to be boarded, the moving speed is obtained from the distance between the two points moved in unit time on the indoor coordinates (106), and the current position of the person 12 to be boarded and the distance and movement to the hall side door 9 are determined. The arrival time is calculated from the speed (10

Next, processing is performed to determine whether the waiting state of the car 6 is to be continued or terminated (110 to 112).

As a judgment item, if the time after the car 6 enters the standby state does not exceed the preset maximum waiting time (NO at 110), the weight in the car calculated by the weight measuring device 7 The calculated value obtained by adding the number of the passengers 13 in the car 6 and the number of the planned passengers 12 is smaller than the value of the number of passengers in the elevator (N in 111).
O), if the above two conditions are satisfied, the system waits until the prospective passenger gets on the elevator (N at 112).
O) When the passenger 12 arrives in the car 6 (112)
YES), the standby state of the car 6 is ended (113).

If the time after the car 6 enters the standby state exceeds the preset maximum waiting time (YES at 110), it is calculated from the weight in the car calculated by the weight measuring device 7. A value obtained by adding the number of the passengers 13 in the car 6 and the number of the scheduled passengers 12 is larger than the value of the number of passengers in the elevator (YES in 111), and more than 2
If one of the two conditions is determined, the waiting state of the car 6 is terminated at that time (114), and an elevator hall call is generated before the occupant 12 who could not board the vehicle arrives at the hall side door 8. (115).

[0017]

As described above, according to the first aspect of the present invention, it is determined whether or not the elevator is to be in the standby state based on the arrival time of the prospective passenger, and it is determined that the elevator is to be in the operating state. When there is no elevator to be on standby, an elevator operating device capable of appropriately operating the elevator can be provided by generating an elevator call to the floor.
