Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operation control of a car of a self-propelled elevator.

[0002]

2. Description of the Related Art A conventional elevator has a structure in which one car is arranged in one hoistway, such as a system using a hydraulic plunger (hydraulic elevator) or a reel type elevator for relatively small-volume transportation. With the exception of, most of the methods are the method of connecting the cage and the counterweight with a rope.

A typical structure of the conventional elevator shown in FIG. 6 will be described.

In the hoistway, a car 1 and a counterweight 2 are arranged by providing guide rails (guide rails) 3 and 4, respectively, and a sheave 6 and a deflecting sheave of a hoisting machine 5 installed in a machine room above the hoistway. A rope 8 is used to connect the ropes via 7, etc. When the rotation direction of the drive motor of the hoisting machine 5 is rotated normally or reversely, the car moves up in accordance with the rotation direction,
Move down.

In such a conventional elevator structure, it is sufficient to drive the car by the driving force corresponding to the unbalanced load with the counterweight, except for the traveling loss due to the machine.
There is an advantage that the capacity of the drive unit and the control unit can be small. Furthermore, performance,
It is a system established with safety.

In recent years, there are many cases where a plurality of elevators are installed side by side with the rise of the building and the scale of the building. In that case, in order to improve the operation efficiency of the elevator and the service of the elevator users, Group management control is performed to allocate elevators that respond to hall calls on each floor reasonably and promptly using a small computer such as a microcomputer.

In addition to the current system as described above,
Various new systems have been proposed to meet the demands of skyscrapers (for example, those described in the magazine NIPPON STEEL MONTHLY).

One of them is a self-propelled elevator in which the car itself travels without using a rope. By providing running paths vertically and horizontally inside the building, not only one car can run vertically but also horizontally.

Unlike the conventional elevator in which one car is installed in one hoistway, this system is capable of running a plurality of cars in one hoistway, and is extremely efficient for passenger transportation. ..

FIG. 2 is an example (a diagram in the above-mentioned document) showing an operation image of a vertical and horizontal self-propelled elevator.

A linear motor secondary conductor 10 is installed in each of a plurality of cars 9 and a driving thrust is obtained by a linear motor primary conductor (coil) 11 installed in a hoistway, and a brake 12 is provided as a safety device. A shock absorber 13 for absorbing the impact caused by the mutual collision of the baskets and a superconducting magnet 14 for connecting and traveling are installed. Further, on the uppermost floor, a lifting machine 15 and a movable plate 16 for horizontal (horizontal) traveling,
A hydraulic jack 17 is also installed on the bottom floor so that a plurality of cars can run on one hoistway.

FIG. 3 is an example of a basic configuration showing a method of supplying drive power, and is a method of installing control devices corresponding to the number of cars. However, in order to clarify the structure, only the ascending / descending direction is described.

The primary coil on the hoistway side is divided into a plurality of sections,
This is a system in which the connection between the primary coil and the control device of each car is switched for each section through a switch as the car travels.

[0014]

In the elevator system having such a structure, it is necessary to control the operation of the self-propelled elevator car group so that a plurality of individual self-propelled cars do not collide with each other.

As described above, the operation image of the elevator traveling in the vertical and horizontal directions and the method of supplying the driving power source of the linear motor for the driving power have been shown, but various methods can be considered for these operation control systems.

It is an object of the present invention to provide an elevator operation control method suitable for safely and efficiently traveling a plurality of elevator cars that can travel vertically and horizontally within one hoistway.

[0017]

The present invention does not determine the operation of an elevator in response to a passenger's call, but a group of a plurality of elevators actively circulates in the same cycle for all units based on a constant traveling pattern. It is to let.

That is, a case in which a plurality of cars are circulated in a fixed traveling path that makes one round and is closed, and as an example, a case will be described in which there are two groups for each floor stop and designated floor stop.

A plurality of hoistways are provided on the upper, lower, left and right sides so as to cross each other, and a mechanism capable of running vertically and horizontally in the hoistways and an elevator car having a large thrust linear motor are arranged.

Elevator car position detecting means for detecting the position of the car, door state detecting means for detecting the door open / closed state of the elevator car, and a plurality of the elevator car groups circulate based on the detection result. Thus, the operation control means of the elevator that supplies power to each linear motor is provided and configured.

The elevator door state detection means detects the open / closed state of the door, and based on this detection, when the door changes from the door open state to the all door closed state, the traveling pattern is obtained from the elevator position obtained by the elevator position detector. Based on this, the floor to be stopped next is determined, and the elevator is driven to the floor.

[0022]

[Function] A group of cars are made to travel in a fixed cycle in a closed closed circulating road at each floor stop. The other group of cars are made to travel in a fixed cycle at a designated floor stop in another travel route provided with a similar route.

Passengers can efficiently connect to these two groups and arrive at the destination floor efficiently.

[0024]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in FIGS.

FIG. 1 is an example of an elevator operation concept.

A designated floor stop basket 40 that stops at the designated floor
Are circulated in the hoistway 43 for stopping on the designated floor.

A group of 41 cars for stopping each floor that stop on each floor are circulated in a hoistway 45 for stopping each floor.

The replenishment car 42 is replenished or stored through the standby passage 44 as needed according to the traffic demand.

Operation management of the elevator group shown in FIG. 1 will be described with reference to FIGS.

As shown in FIG. 4, the overall configuration of the system is a unit controller 6 for controlling the opening and closing of doors, brakes and the like.
4 to 66, group control units 61 to 63 for controlling the traveling of the designated floor stop car or each floor stop car in group units, adjustment of the number of each group according to traffic demand, stop floor and speed of each group, etc. The operation management control unit 60 changes and schedules.

When the traffic demand changes, the operation management control unit 60 controls the number and speed of control of the group of cars sent from the group management control units 61 to 63 through the transmission line 70, and the optimum number and speed of control based on the stop floor. , The stop floor is determined, and the determined number of control units and speed and the stop floor are determined for each group management control unit 61, 62, 63.
A command is transmitted to the device via the transmission path 70.

The operation management control unit 60 adjusts the number of controlled vehicles. When increasing the number of controlled vehicles, the operation management control unit 60 travels from a hangar (not shown) to the position of the elevator group that circulates the supplementary car, and passes it to the group management control unit that controls the elevator group at the position. Then, the group management control unit recognizes the supplementary car as a control target and performs the group management control including the supplementary car.

On the contrary, when the number of cars in the elevator group is reduced, the group management control unit controlling the elevator group moves the cars that are circulating to the predetermined number to the predetermined position and excludes them from the control target. To the operation management control unit 60.
Then, the operation management control unit 60 moves the evacuation car to the storage.

The group control units 61 to 63 stop the plurality of cars on the basis of signals such as door open / close states transmitted from the plurality of single unit control units respectively managed via the transmission paths 71 to 73.
Run in the same cycle.

The unit control units 64-66 are group control units 61-6.
3 receives the stop completion signal from the transmission lines 71 to 73 via the transmission lines 74 to 76, the door opening / closing contacts 67 to 69 via the transmission lines 74 to 76.
To open and close the door. Further, the single unit control unit is capable of constantly detecting the open / closed state of the door via the transmission lines 74 to 76.

The signals of the group control unit and the single unit control unit in FIG. 4 and the process of processing the signals will be described with reference to FIG.

In the group control unit 61, the door state detection unit 80 includes a unit control unit 641 to 64n via a group control transmission line 71.
The open / closed state of the door of each elevator is detected from the unit control circuits 831 to 83n. The detection signal detected by the door state detection unit 80 is transmitted to the operation control unit 82. When it is determined that this signal is from door open to completion of all door close, the operation control unit 82
Determines the next stop floor of the car based on the position information of each car detected by the position detection unit 81 from the unit control circuits 831 to 83n via the transmission filter 71, and supplies power to the linear motor.

Therefore, according to the present embodiment, since a plurality of cars are collectively controlled in the same cycle and are circulated, the cars can be easily operated without collision.

Further, since the group of cars for stopping on each floor and the group of cars for stopping on the designated floor are provided side by side, it is possible to improve the transportation efficiency and shorten the waiting time.

[0040]

According to the present invention, instead of operating in response to a call request from a passenger, the group control device actively drives the car to circulate, and also for stopping each floor and stopping the designated floor. Since the elevator group is installed side by side, the efficiency of transportation and the waiting time can be shortened.
