- Car A has a car call on the 10th floor as shown by the circle, and moves in the UP direction.
- car B is traveling in the UP direction with car call on the ninth floor as indicated by the circle, the forwarding car and the forwarding floor are set and the forwarding car is forced to the forwarding floor. The operation for stopping will be described.
- step S91 the number of passengers expected to occur in the future is predicted from the number of passengers generated on each floor in the past by means of the number of passengers prediction 19.
- step S91 After predicting the number of passenger occurrences in step S91, the process proceeds to step S92, and the passenger occurrence distribution calculating means 20 calculates the passenger occurrence distribution of each floor from the predicted number of passenger occurrences.
- step S92 After the passenger occurrence distribution is calculated in step S92, the process proceeds to step S93, and the accumulated car stay time on each floor is calculated by the car bridging time calculation means 21. After calculating the stay time in step S93, proceed to step S94, and use the car assignment means 15 to first divide the stay time from the passenger occurrence distribution to calculate the stay ratio on each floor. I do. For example, if the passenger occurrence distribution is shown in Fig. 39 and the car stay time distribution is shown in Fig. 59, the car stay ratio at each floor at this time is as shown in Fig. 60.
- step S94 After calculating the car stay ratio in step S94, the process proceeds to step S95, and the car assignment means 15 checks whether the car stay ratio is within the specified value. If the value does not exceed the specified value, the process ends.If the value exceeds the specified value, proceed to step S96), set the forwarding floor and forwarding car from the car stay ratio, and set the forwarding car. Is forcibly stopped on the forwarding floor. For example, if the forwarding floor is the one that can respond to the floor with the highest car stay ratio and the forwarding car to the floor with the highest car stay ratio, the forwarding floor is the fourth floor and the forwarding car is car B. .
- the forwarding car B is forcibly stopped at the forwarding floor (fourth floor).
- the difference in the service available time to each floor (the difference between the maximum expected arrival time and the minimum expected arrival time) is reduced to equalize the service available time to each floor.
- Service variability can be reduced, and services can be provided in accordance with the predicted ratio of passenger occurrences, shortening the average waiting time, and the ratio of passenger occurrences and stay time In accordance with this, it is possible to provide an elevator group management control device that can improve the service.
