[0024] Figure 1 ~ Figure 3 Regarding Embodiment 1 of the present invention, figure 1 is a diagram schematically showing the overall structure of an elevator system with a group management control device, figure 2 It is a block diagram showing the structure of the main part of the elevator group management control device, image 3 It is a flowchart showing the operation of the elevator group supervisory control device.
[0025] exist figure 1 In the figure, 1 represents a car carrying a plurality of elevators for lifting and lowering users and / or goods in the hoistway. Each upper end of these cars 1 is connected to one end of a main rope 2 , and the other end of the main rope 2 is connected to an upper end of a counterweight 4 . In addition, the intermediate portion of the main rope 2 is wound around the drive sheave of the hoisting machine 3 provided on the ceiling of the hoistway.
[0026] In this way, the car 1 and the counterweight 4 are suspended in the hoistway by ...

Provided is an elevator group management control device able to efficiently consume regenerated power from the elevator during powered operation. For this reason, an elevator group management control device for controlling a plurality of elevator cars by managing the same as one group, wherein the control device is provided with a prediction unit (10c) for predicting for a certain elevator car, on the basis of the movement direction and load of the elevator car, whether operation until the next stopping floor will be regenerative operation or powered operation and the time for regenerative (powered) operation, and a command setting unit (10d) for calculating the overlap time between the regenerative (powered) operation of the elevator car and the regenerative powered (poweredregenerative) operation of another elevator car, obtaining a running speed from a longer overlap time by calculating overlap time while the elevator car changes running speed, and setting a command value for the running speed of the elevator car, when the other different elevator car is predicted to realize powered (regenerative) operation during the time predicted for regenerative (powered) operation of the first elevator car.
Description
technical field [0001] The invention relates to the field of elevators, in particular to an elevator group management control device. Background technique [0002] Generally, in an elevator system, the elevator car and the counterweight are connected by main ropes, and the weight of the counterweight is set to be balanced with the car when half the number of rated passengers rides. Therefore, when an empty car without passengers is raised, the potential energy of the lowered counterweight rotates the hoisting machine, and the hoisting machine functions as a generator to regenerate electric power. On the contrary, when the empty car is descending, the traction machine becomes power operation and consumes electric power in order to raise the counterweight. [0003] In the existing elevator group management control device, there is known such a device as follows: the unbalanced load of both is detected according to the weight of the counterweight and the load of the car, and t...
