Abstract

PROBLEM TO BE SOLVED: To prevent a cage positioned adjacent to a cage under a work from passing through the cage under a work by a method wherein the cage adjoining the cage under a work is retrieved and other cages than those cages are made to wait in a dispersion state in a non-deciding dispersion waiting zone. SOLUTION: When a host control panel 16 performs retrieval of a cage (n) under a work, a cage D under a work is retrieved. When a cage (m) adjoining the cage (n) under a work is then retrieved, an adjoining cage C is retrieved. A dispersion waiting zone is decided from a dispersion waiting zone in a way to match with the adjoining cage C. Thus, the cage C adjoining the cage D under a work does not pass through the cage D. Remaining cages A and B are decided in respective non-deciding dispersion waiting zones near the respective cages.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for efficiently operating and managing a plurality of elevators as a group according to changes in traffic demand.

[0002]

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 control elevator is composed of a plurality of car control panels for controlling the operation of each car by inputting information of each elevator car, and inputting information from the plurality of car control panels and hall call information to meet traffic demand. And a group control for efficiently operating a plurality of cars while responding to changes in the number of cars. When a hall call occurs on a certain floor, the group control panel calculates the time during which each car can respond to the hall call, and assigns the car that can respond the earliest to the hall call.

On each car, a door operator for opening and closing the door and other various devices are provided, and electric devices are provided on the inner wall surface of the hoistway. Therefore, it is necessary to occasionally maintain and inspect the equipment on these cars and the electric equipment on the hoistway. This maintenance / inspection work is performed for each car one by one, and the car adjacent to the car being operated is operating normally.

On the other hand, in a group management elevator, when traffic demand is low, a distributed standby is performed in which a plurality of cars are distributed to appropriate floors. This is so that each car can respond to a newly generated hall call in as short a time as possible.

[0005]

A worker riding on a car sometimes leans out of the car to work. However, the car adjacent to the car on which the worker is riding is operating normally. For this reason, if an adjacent car passes for standby for dispersion while the worker is leaning out of the working car, this car will collide with the worker and lead to a major accident. There was a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to disperse a car adjacent to a working car in consideration of the safety of the working car.

[0007]

In order to achieve the above object, according to the present invention, a plurality of elevators installed as a group in a building and a position of each car provided in each elevator are determined. Position detecting means for detecting, a plurality of car control panels for controlling the operation of each car by inputting information of the car of each elevator, and efficiently operating a plurality of cars while responding to changes in traffic demand, A higher-level control panel for distributing and waiting a plurality of cars, searching for a car n in operation at the higher-level control panel, calculating a decentralized standby zone for other cars excluding this car n, and The adjacent car m is searched, the distribution standby zone of the car m is determined, and the cars other than the cars n and m are distributed and standby in the undetermined distribution standby zone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 to 3 are views showing an embodiment of a group management elevator according to the present invention.

In FIG. 1, reference numerals 1, 2, 3, and 4 denote car control panels for a plurality of elevators provided in a building, and the car control panels 1, 2, 3, and 4 correspond to respective cars A, B, and C. , D are controlled. To the car controls 1, 2, 3, and 4, car call signals are output from car operation panels 15, 16, 17, and 18 provided in the cars A, B, C, and D. In addition, car A,
Inspection switches 19, 20, 21, and 23 for stopping B, C, and D at arbitrary positions for maintenance and inspection.
22 are provided.

A counterweight 8 is attached to the car A via a main rope 7, and the main rope 7 is hung on a drive sheave 9 a of a hoisting machine 9.
Is controlled by the car control panel 1 via the inverter 10. A governor rope 11 is attached to the car A. The governor rope 11 is hung on a sheave 12 for a governor, and the car is controlled by a rotary encoder 13 (position detecting means) provided on the sheave 12 for the governor. The position has been detected. The car control panels 2, 3, and 4 also operate the cars B, C, and D by inputting and outputting signals in the same manner.

Although car position information and car call information are output from the car control panels 1, 2, 3, and 4 to the upper control panel 16,
A hall call signal is also output from the hall button 17 for each car (only one car is shown in the figure, and the others are omitted) provided on each floor to the upper control panel 16. The upper control panel 16 controls the operation of the car according to traffic demand, such as the position and driving direction of the car that changes every moment, the status of car calls and hall calls, the load status of the car, the status of the departure interval of the car, and the like. And the most appropriate car is assigned to the waiting floor. The car control panels 1, 2, 3, and 4 open and close doors and run the car in accordance with commands from the upper control panel 16.

Next, referring to a flowchart shown in FIG. 2, a description will be given of the operation of the group management elevator in the distributed standby mode.

In order to perform maintenance and inspection of the car D, the inspection switch 22 on the car operation panel 18 of the car D is pressed (step S ₁ ). Then, basket D
Stops at an arbitrary floor (for example, the third floor) and performs maintenance and inspection work.

In the upper control panel 16, the car n
Is searched, the car D in operation is searched (step S ₂ ). Next, since the car D in operation cannot be placed on standby for distribution, the other three cars A, B, and C are placed on standby for distribution. So, these three cars A, B, C
Is calculated (step S ₃ ). That is, as shown in FIG. 3, in the building on the ninth floor, one of the three cars is made to wait on the lobby floor (the first floor), and the remaining two cars are kept on standby.
Cars will be distributed and waited on the 8th floor. Accordingly, the dispersion waiting zone for this three cages would that lobby floor zone P _0, 2 floor 5 floor zone P _1, 6-floor to 9 floor zone P _2.

Next, when the car m adjacent to the car n in operation is searched, the car C adjacent to the car m is searched (step S ₄ ). Next, the distributed standby zone is determined according to the position of the adjacent car C from among the distributed standby zones P ₀ , P ₁ , and P ₂ . That's the position of the car C is the fourth floor, the dispersion waiting zone of the car C is determined on the second floor 5 floor zone P ₁ (step S _5). Then, the car C does not move and stands by on the fourth floor. Therefore, the car C adjacent to the car D under construction does not pass through the car D.

Next, the positions of the remaining cars A and B are detected (step S ₆ ). Next, it is calculated which of the remaining cars A and B is closer to the undetermined distributed standby zones P ₀ and P ₂ (step S ₇ ). Next, the remaining basket A,
B, the closer undetermined distributed standby zone P ₀ ,
It is determined to be P _2. Cars A and B are located on the 3rd and 4th floors, respectively.
On the floor, car A is in zone P ₀ on the lobby floor, and car B is 6
Each determined downstairs to 9 floor zone P ₂ (Step S _8). Then, the car A is moved from the third floor to the lobby floor, and the car B is moved from the fourth floor to the seventh floor.

[0017]

As described above, according to the present invention,
The car n in operation is searched, the distribution standby zone of the other car except this car n is calculated, the car m adjacent to the car n is searched, the distribution standby zone of the car m is determined, Since the cars other than n and m are distributed and standby in the undetermined distribution standby zone, when performing the distribution standby of the car,
The car adjacent to the working car does not pass through the working car, and the safety of the working car is improved.
