Group management and control system for elevators |
摘要 |
A group management and control system for elevators can ensure high transport efficiency while an ordinary hoist and motor are employed, and can perform appropriate group management and control without causing a wrong arrival preannouncement even when a plurality of elevators travel at different accelerations. The group management and control system for elevators includes a load detecting unit for detecting a load in each elevator cage; an acceleration setting unit for setting an acceleration and a jerk rate of each elevator to upper limit values in accordance with a detected result of the in-cage load from the load detecting unit when the in-cage load is within a certain range from a balanced state; an estimation processing unit for computing estimated time at which each elevator will arrive each floor on the basis of the detected result of the in-cage load and the set acceleration; an assignment control unit for assigning an appropriate elevator in response to a call issued from an elevator hall in consideration of an estimation processing result; and an operation control unit for controlling operation of each elevator in accordance with an assignment result.
