Abstract

PURPOSE: To prevent passengers from waiting long by operating expected positions of respective cars after pass of a specified time in the case where each car is allotted when a hall call is generated, selecting the expected positions most equally apart from each other, and allotting the car corresponding to that. CONSTITUTION: When a hall call is generated, cars 1-3 are set to correspond to each other, and expected positions of the respective cars 1-3 after pass of a specified time are operated. Information indicating circularly disposed positions, from a lobby floor to the uppermost floor, and from the uppermost floor to the lobby floor, is inputted to a RAM in a group control panel 16. It is when the cars 1-3 are not deflected but are most equally apart from each other that either of the cars 1-3 can respond most speedily when the next hall call is generated after pass of a specified time. When the hall call is generated after pass of the specified time, therefore, expected positions of the cars 1-3 most equally apart from each other without deflecting are selected, and the car corresponding to that is allotted.

2. Description of the Related Art In recent buildings, in order to efficiently operate a plurality of elevators, a group management elevator for managing these elevators as one group is provided.
This group-controlled elevator uses multiple car control panels that control the operation of each car by inputting the information about each elevator car, and the traffic demand by inputting information from these multiple car control panels and hall call information. It is equipped with a group control panel that efficiently operates multiple cars while responding to changes in

When a hall call occurs on a certain floor, the group control panel calculates the time for which each car can respond to the hall call, and assigns the car that can answer the earliest to the hall call.

For example, if an upward hall call occurs on the 10th floor in FIG. 6, the cars 101, 102, 1
03 CRT (Car Resp
onseTime) is as follows.

The basic time relating to the predicted arrival time is calculated as the following value.

Acceleration time 4 seconds Number of floors traveling during acceleration time 1 floor Deceleration time 5 seconds Number of floors traveling during deceleration time 1 floor 1st floor running time at rated speed 1.2 seconds Door opening / closing time 8 seconds 1st floor Travel time 9 seconds CRT of car 101 = 1F to 2F (acceleration time) + 2F to 9F + 9F to 10F (deceleration time) = 4 + 1.2 x 7 + 5 = 17.4 seconds CRT of car 102 = 5F to 6F (acceleration time) ) + 6F to 9F + 9F to 10F (deceleration time) = 4 + 1.2 × 3 + 5 = 12.6 seconds CRT of the car 103 = 7F to 8F (deceleration time) + door opening / closing + 8F to 9F (acceleration time) + 9F to 10F (deceleration time) ) = 5 + 8 + 4 + 5 = 22 seconds As described above, the car 102 has the fastest CRT, so the car 102 is made to respond to the hall call.

[0007]

[Problems to be Solved by the Invention] By the way, the basket 102
After elapse of a predetermined time (20 seconds after)
As for the position of the car, as shown in FIG. 7, the car 101 is traveling on the lobby floor, and the cars 102 and 103 are traveling on the 10th and 11th floors, respectively. That is, the cars 101, 102, 103 of this group management elevator are located on one side of the upper floor and on the other side of the lower floor. Therefore, when a hall call occurs on the middle floor (6th and 7th floors) after a predetermined time has passed, the car 101,
Since 102 and 103 are away from the middle floor, it takes time to answer the hall call.
As a result, there is a problem in that passengers waiting for a car to arrive on the middle floor will last a long time.

It is an object of the present invention to provide a group control elevator which prevents passengers in the hall from waiting too long when a hall call occurs after a lapse of a predetermined time.

[0009]

In order to achieve such an object, according to the present invention, a plurality of elevators are installed in a building as a group, and the information of the car of each elevator is input. A plurality of car control panels that control the operation of each car 1, 2, 3 ..., and a plurality of car control panels that respond to changes in traffic demand by inputting information from these car control panels and hall call information. When a hall call occurs, the expected position of each car 1, 2, 3, ... After a predetermined time when the car 1 is assigned in the group control panel ( A) is calculated, and the expected position (B) of each car 1, 2, 3 ... After a predetermined time when the car 2 is allocated is calculated, and the predetermined time elapses when the car 3 is allocated in the same manner. Predicted position (C) ... is calculated, and this expected position of each car 1, 2, 3 after (A), (B),
(C) ... The cars whose cars 1, 2, 3 ... Are most evenly separated are selected, and the car corresponding to this predicted position is assigned to the hall call.

[0010]

When the next hall call is generated after the lapse of a predetermined time, one of the cars 1, 2, and 3 can respond to the next hall call earliest. , 3 are not evenly offset and are most evenly spaced from each other. Therefore, the expected positions (A), (B),
In (C), the car with the cars 1, 2, and 3 separated from each other most evenly is selected and assigned to the first hall call.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 5 are views showing an embodiment of a group control elevator according to the present invention.

In FIG. 1, reference numerals 1a, 2a and 3a denote car control panels for a plurality of elevators installed in a building. The car control panels 1a, 2a and 3a control the operation of the respective cars 1, 2 and 3. It is for doing.

A car call signal is output from the car operation panel 6 provided in the car 1 to the car control panel 1a. Also,
A counterweight 8 is attached to the car 1 via a main rope 7, and the main rope 7 is hung on a drive sheave 9a of a hoisting machine 9, which is driven by an inverter 10. It is controlled by the car control panel 1a. Further, a governor rope 11 is attached to the car 1, the governor rope 11 is hung on a governor sheave 12, and the position of the car is detected by a rotary encoder 13 provided on the governor sheave 12. There is. Further, the car 1 has a door motor 1 for driving the car side door.
4 is provided, and the door motor 14 is a door inverter 1
Controlled by the car control panel 1 via 5. Similarly, the car control panels 2a and 3a also operate by inputting and outputting signals.

Car position information, car call information, etc. are output from the car control panels 1a, 2a, 3a to the group control panel 16. The group control panel 16 receives a hall call from a hall button 17 provided on each floor. The signal is also output. The group control panel 16 controls the position and driving direction of the car that changes from moment to moment, the status of car calls and hall calls, the load status of the cars, the status of the car departure intervals, etc. in order to manage the operation according to the traffic demand. Various kinds of traffic information are processed, and the most suitable car is assigned to the waiting floor. Also,
The car control boards 1a, 2a, 3a open and close doors and run cars according to commands from the group control board 16.

Here, in order to indicate the positions of the cars 1, 2, and 3 after a predetermined time (about 20 seconds) has elapsed when a hall call is generated, the group control panel 16 is provided with the graphic information as shown in FIG. Input to RAM. That is, the floors from the lobby floor upward (2FUP (up) to 11FUP (up))
And from the 12th floor to the lower floor (11 FDN (down) ~
2FDN (down) and divide them into a ring. In addition, it is only the car that is traveling in the upward direction that can answer the hall call in the upward direction, and the floor that is in the up side and the floor that is in the down side are divided. This is because only the car traveling downward can do it.

1) The car 1 after the predetermined time has elapsed since the car 1 was made to respond to the hall call on the 10th floor in FIG.
The expected positions (A) of 2 and 3 are as follows: Car 1: 1F to 2F (acceleration time) + 2F to 9F + 9F to 10F (deceleration time) + door opening and closing time = 4 + 1.2 × 7 + 5 + 8 = 25.4 ( For this reason, the car 1 is opening and closing the door on the 10th floor.

Car 2: 5F and non-directional stop Car 3: 7F to 8F (deceleration time) + 8F door opening / closing + 8F to 9F (acceleration time) + 9F to 11F = 5 + 8 + 4 + 1.2 × 2 = 19.4 Therefore, I am driving upward near the 11th floor.

This is shown in FIG. 3 when it is shown in the ring-shaped drawing.

2) The expected positions (B) of the cars 1, 2, and 3 when the predetermined time has elapsed since the car 2 was made to respond to the hall call are as follows.

Car 1: Stopping on the lobby floor Car 2: 5F to 6F (acceleration time) + 6F to 9F + 9F to 10F (deceleration time) + 10F and door time = 4 + 1.2 × 3 + 5 + 8 = 20.6 Therefore, car 2 is Doors are opening and closing on the 10th floor.

The car 3 is traveling upward near the 11th floor.

This is shown in FIG. 4 when shown in the above-mentioned annular drawing.

3) The expected positions (C) of the cars 1, 2, and 3 when the predetermined time has elapsed since the car 3 was made to respond to the hall call are as follows.

Car 1: Stopping on the lobby floor Car 2: Stopping non-directionally on the 5th floor Car 3: 7F to 8F (deceleration time) + door opening and closing time + 8F to 9F (acceleration time) + 9F to 10F (deceleration time) = 5 + 8 + 4 + 5 = 22 seconds Therefore, the car 3 is decelerating near the ninth floor.

This is shown in FIG. 5 when it is shown in the ring-shaped drawing.

Here, when one of the cars 1, 2, and 3 can respond earliest when the next hall call is generated after a lapse of a predetermined time, the cars 1, 2, and 3 are not offset from each other. This is the case when the spaces are most evenly separated. Therefore, if one of the predicted positions (A), (B), and (C) that is most evenly spaced between the cars 1, 2, and 3 is selected, the predicted position (C) shown in FIG. Become. Therefore, considering that the passengers will not last long in the hall when a later hall call occurs after the lapse of a predetermined time, the car corresponding to the expected position (C) will be the 10th floor for the first hall call generated on the 10th floor. It will be assigned to the floor.

[0027]

As described above, according to the present invention,
When the car 1 is assigned, the expected position (A) of each car 1, 2, 3 ... After a predetermined time has elapsed is calculated, and when the car 2 is assigned, each car 1, 2, after the predetermined time has elapsed
When the expected positions (B) of 3 ... Are calculated and the cars 3 are similarly assigned, each car 1 after a predetermined time has passed,
The predicted positions (C) of 2, 3, ... Are calculated, and the ones in which the cars 1, 2, 3 are most evenly separated are selected from these predicted positions (A), (B), (C). Since the car corresponding to this predicted position is assigned to the hall call, even if a hall call occurs after a predetermined time elapses, passengers in this hall do not last long.
