Technical Field

Embodiments of the present invention relate to a group management control system for elevators.

Background

Nowadays, a hybrid DCS (Destination Control System) of an elevator is known. In a group management system for elevators to which this hybrid DCS is applied, there are a general floor to which a call in the vertical direction (up-down call) is input at an elevator boarding location, and an elevator boarding location destination call registration device installation floor to which a destination floor (destination call) is input at an elevator boarding location. As an example of a method for implementing the hybrid DCS, there is a method of controlling the operation of cars of a plurality of elevators by using both a 1 st allocation algorithm unit for selecting a car to be allocated to an allocation request for an up-down call in the up-down direction and a 2 nd allocation algorithm unit for selecting a car to be allocated to an allocation request for a destination call registered at a boarding location.

However, in the hybrid DCS, if car assignment to up-down calls or destination calls is performed without considering the number of users, each assignment algorithm unit assigns cars based on inaccurate assignment evaluation. Therefore, it is difficult to make the group management performance good in consideration of the average of each user.

The indices of the group management performance include a waiting time, which is a time from when a user registers a call at the elevator riding place until a car to be ridden responds at the elevator riding place, and a service time, which is a time from when a user registers a call at the elevator riding place until a car to be ridden responds at the elevator riding place and then responds at a destination floor of the user.

However, the group management system of the elevators is not necessarily able to directly evaluate these service indicators. For example, at a general floor where an up-down call is registered, it is difficult for the group management control system to grasp the number of users who get on the car or the destination floors of the users at the time of a response at the time point when the call is registered.

Disclosure of Invention

The problem to be solved by the present invention is to provide a group management control system capable of improving group management performance by calculating a "response prediction time" which is a prediction value of a time from when a call is registered to when a car responds to the call, and making an effort to evaluate the index as accurately as possible.

The elevator group management control system of the embodiment is an elevator group management control system having a 1 st assignment algorithm unit and a 2 nd assignment algorithm unit, wherein the 1 st assignment algorithm unit is an algorithm unit for selecting a car assigned to an up-down call in which one of an up direction and a down direction is registered before the elevator is taken from a plurality of cars, the 2 nd assignment algorithm unit is an algorithm unit for selecting a car assigned to a destination call in which a destination floor is registered before the elevator is taken from a plurality of cars, and an assigned call counting part calculates a weighting coefficient corresponding to the number of destination calls assigned to each car, each departure floor, and each direction and notifies the weighting coefficient to the 1 st assignment algorithm unit. In the 1 st allocation algorithm unit, the storage control unit stores and controls the weighting coefficients notified from the allocated call counting unit in the weighting coefficient storage unit. The 1 st operation prediction evaluation unit calculates an evaluation value including a response prediction time of each car, which is a time from registration of an up-down call to a predicted response, the evaluation value reflecting the weighting coefficient stored in the weighting coefficient storage unit. Then, the 1 st assigned car selection unit selects a car to be notified to the car control unit performing the operation of the car, and to which a call in the up-down direction of the elevator is assigned, based on the evaluation value of each car calculated by the 1 st operation prediction evaluation unit.

According to the group management control system for elevators configured as described above, the group management performance of the hybrid DCS can be improved.
