Abstract

PURPOSE:To prevent a passenger from missing an elevator and enhance the efficiency of group control over the elevator as well as to improve the extent of service to passengers at other floors. CONSTITUTION:Plural units of elevators are put into service for plural stories of service floors, thereby performing an operation of elevator group control which selects and determines an optimum elevator for assignment to a common hall call generated in each of these elevators in service. In this case, where plural units of elevators being an standby at a floor generated of the hall call or being decelerated exist, when the hall call is generated, an assigning process S33 assign an elevator nearer to a hall button S31 pushed out of these elevators, or in the case where there in only one elevator being on standby or decelerated at the floor generated of the hall call, only at a time when this elevator is separated as far as more than a specified distance from the hall button S31 pushed, elevator door opening time is lengthened longer than the usual time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control method and apparatus, and in particular, it can prevent passengers from delaying passengers, improve efficiency of group management control, and improve services to passengers on other floors. The present invention relates to an elevator group management control method and device.

[0002]

2. Description of the Related Art Generally, in a large-scale building, a group management control is used in which a plurality of elevators arranged in parallel are grouped as a group to centrally manage a common landing call and efficiently determine traffic demand. That is, when a passenger registers a hall call, a computing device using a microcomputer or the like selects an optimum elevator in consideration of various states such as the position of each elevator, the driving direction, another car call, and the state of a hall call. It decides (assigns) and performs services.

On the other hand, this type of group management control requires a method of informing passengers which elevator is arriving, but recently, two types of methods have become common. First of all, one of the methods is, when the hall call is registered,
It is a method to immediately turn on the forecast light of the elevator determined to be the most suitable for the hall call, and when the elevator actually approaches the floor and starts deceleration, the forecast light is changed to blinking as an arrival light. Prompt passengers to get on board (this method will be referred to as a forecast light). Also another 1
One method is a method in which the forecast light is not turned on, but the arrival light is blinked at the start of deceleration (hereinafter, this method is referred to as no forecast light).

By the way, when the distance between the ends of the elevator hall is long, such as when the elevator hall is large or when a plurality of elevators are arranged side by side due to the structure of the building, the elevator farthest from the pushed hall button is In the case where the passengers are assigned, the traveling distance of the passengers becomes long and it takes a long time to get in, so that the door of the car may be closed before the passengers get in the elevator.

In particular, when the elevator is on the floor waiting for the door to close, the door will open as soon as the hall button is pressed, so it is often impossible to get in. Also, when the elevator arrives from another floor, if it has a forecast light, you can know which elevator arrives when you press the hall button, so passengers can move in advance, but in the case of no forecast light, Since it is possible to know which elevator arrives for the first time when the deceleration of the elevator starts, the passengers may not be able to travel for a short time because they cannot travel. Further, even when the vehicle is equipped with a forecast light, when it is assigned to an elevator that is decelerating, there is a possibility that the passengers are similarly short in their travel time and unable to board.

Therefore, in order to solve the above-mentioned problems, recently, when an elevator that responds to a landing button that has been pressed is waiting for the door to close on that floor, the elevator door should not be opened for a certain period of time. It has been proposed to set the time to open or to open the door longer than usual.

However, in the above method, the elevator stop time on that floor becomes longer than usual, so that
There is a problem that the efficiency of group management control is reduced, and the service to passengers on other floors is reduced.

[0008]

As described above, in the conventional elevator group management control method, passengers may be delayed and the efficiency of group management control may deteriorate, so that passengers on other floors may not be serviced. There was a problem of lowering.

An object of the present invention is to provide an extremely reliable elevator group management control method capable of preventing passengers from getting behind the vehicle, improving efficiency of group management control, and improving service to passengers on other floors. And to provide a device.

[0010]

In order to achieve the above object, first, in the invention described in claims 1 and 3, a plurality of elevators are put into service for a plurality of service floors, and each of these elevators is activated. In an elevator group management control method and apparatus for selecting, determining and allocating an optimum elevator to a common hall call that occurs in a vehicle, when a hall call occurs, the floor of the hall button pressed and the hall button at any position Hall call generation processing means for detecting whether
It is determined whether there is an elevator waiting or decelerating on the floor of the hall button detected by the hall call generation processing means, and as a result, when there are a plurality of elevators, the elevator It is configured with allocation processing means for allocating an elevator close to the hall button pressed from the inside and responding, and when a hall call occurs,
When there are a plurality of elevators waiting or decelerating on the floor where the hall call is generated, an elevator close to the landing button pressed from these elevators is assigned and made to respond.

According to the second and fourth aspects of the invention, a plurality of elevators are activated for a plurality of service floors, and an optimum elevator is selected for a common hall call generated in each elevator. In the elevator group management control method and device for determining and allocating, when a hall call occurs, a hall call generation processing unit that detects the floor of the pushed hall button and the position of the hall button, and hall call generation processing. It is determined whether there is an elevator waiting or decelerating on the floor of the hall button detected by the means, and as a result, the elevator is 1
When there is only a stand, only when the elevator is away from the pushed landing button by a predetermined distance or more, allocation processing means for controlling the elevator door opening time to be longer than usual is configured. However, when a hall call occurs, if there is only one elevator waiting or decelerating on the floor where the hall call occurred, this elevator is separated from the pushed hall button by a predetermined distance or more. The door opening time of the elevator is set longer than usual only when the elevator is open.

[0012]

Therefore, in the elevator group management control method and apparatus of the present invention, when a hall call occurs, an elevator waiting or decelerating on the floor is detected, and a plurality of elevators exist. Will give priority to the elevator that is closest to the landing button that was pressed to respond, or if there is only one elevator, the elevator will move a predetermined distance from the landing button that was pressed. Only when they are separated by the above distance, by making the elevator door-open time longer than usual, it is possible to prevent passengers from getting behind and to perform group management control without reducing efficiency, and passengers on other floors. Can improve the service to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing an example of the construction of an elevator hall to which the present invention is applied, in which eight vehicles, No. 1 to No. 8, are grouped. In the figure, 1 is an elevator car, and 2 is the hall buttons A to F, respectively.

FIG. 2 is a block diagram showing an example of the overall configuration of an elevator group management control device according to the present invention. In FIG. 2, 1 is an elevator car, 2 is a hall button (A to
F), 3 is a group management control device, and 4 is an elevator control device provided corresponding to each of the above eight units (elevators).

Here, the group supervisory control unit 3 is composed of, for example, a microcomputer, and performs an arithmetic operation on common hall calls generated in each elevator to select / determine and allocate an optimum elevator. Management control function, when the hall call occurs, the floor of the landing button that was pressed, and the hall call generation processing function that detects the position of the hall button, and the floor of the hall button detected by the hall call generation processing function. If there is an elevator waiting or decelerating, and if there are multiple elevators as a result, assign the elevator closest to the landing button pressed from these elevators and respond. And an assigning processing function. In addition, each elevator control device 4 makes the corresponding elevator service by a control command from the group management control device 3.

Next, a group management control method in the elevator group management control apparatus of the present embodiment configured as described above will be described with reference to the flow charts shown in FIGS. 3 and 4. 3 and 4 are flow charts showing the processing contents of the group management control device 3 according to the present invention.

In FIG. 2, when the passenger pushes the landing button 2, the group management control device 3 performs a logical operation to select and determine the optimum elevator, and the elevator control device 4 services the elevator. The logical operation method and the optimum elevator selection / determination method in the group supervisory control device 3 are publicly known, so that the description thereof will be omitted and the method according to the present invention will be described here.

That is, in FIG. 3, when the hall button 2 is pressed, it is determined in the processing step S31, and the pressed floor is determined in the processing step S32.
The landing button is detected. That is, for example, if the hall button (A) 2 in the upward direction of the fifth floor is pressed, the floor button of the floor of the pushed hall button 2 and the position of the hall button detected are detected, and the process proceeds to the allocation process of process step S33.

Next, in the allocation process, as shown in FIG.
First, No. After the storage table is cleared (processing step S41), the process proceeds to processing step S42. In processing step S42, it is determined for each elevator whether the hall button (A) 2 has been pressed, that is, in the present example, whether the vehicle is not waiting on the fifth floor or decelerating to that floor. As a result, if the corresponding machine exists, the machine No. No. It is set in the storage table (processing step S43).

Next, after the states of all the units have been determined in this way (processing step S44), the number of elevators that meet the conditions, that is, how many elevators are decelerating or waiting on the 5th floor, is counted. (Processing step S
45), if less than two, processing step S4
The process proceeds to the normal allocation process of No. 7.

When there are two or more units, the processing step S
Moving to 46, weighting is performed according to the positional relationship between the elevator concerned and the landing button that has been pressed. That is, the weighting is data that makes it difficult or difficult to assign each elevator depending on the value of the weight, and the data to be weighted is, for example, according to the distance between each elevator and the hall button, It should be set in the ROM area or the like in advance.

Now, in this embodiment, No. 1 in FIG.
1 and No. Suppose Unit 6 is waiting or slowing down on the 5th floor. In this case, the weighting data of the respective units for the hall button (A) 2 is the farthest No. No. 8 becomes the most difficult to allocate, and the closest No. The data that makes it easy to allocate the No. 1 machine is set according to the distance to the hall button (A) 2, and the weight data indicates the No. 1 and No. The No. 6 units are weighted and the assigned units are determined. As a result, No. The passenger assigned the No. 1 vehicle and pressing the hall button (A) 2 can get on the elevator without being late.

As described above, the group management control device 3 of the present embodiment performs the logical operation on the common hall calls generated in each elevator, selects and determines the optimum elevator, and the original group management. Control function, when a hall call occurs, the hall call generation processing function that detects the floor of the pushed hall button and the position of the hall button pressed, and waits on the floor of the hall button detected by the hall call generation processing function It is determined whether or not there are elevators that are operating or decelerating, and if there are multiple elevators as a result, the elevators closest to the landing button pressed from these elevators are assigned and made to respond. When there is a hall call with multiple allocation functions, there are multiple elevators waiting or decelerating on the floor where the hall call occurs. If that is obtained by so as to respond by allocating the elevator close to the hall button pressed from among these elevators.

Therefore, waiting on the floor where the hall call occurs,
Alternatively, when there are multiple elevators that are decelerating, the elevators that are close to the pressed landing button are assigned to respond, which makes it possible to prevent passengers from delaying the ride and shorten the distance traveled by passengers. It is possible to prevent the group management efficiency from being lowered by unnecessarily lengthening the door opening time of the responding elevator, and it is possible to improve the service to passengers on other floors.

In the above embodiment, the group management control device 3
In addition to the original group management control function, when a hall call occurs, it is detected by the hall call generation processing function that detects the floor of the hall button pressed and the position of the hall button, and the hall call generation processing function. It is determined whether there is an elevator waiting or decelerating on the floor of the specified hall button, and if there are multiple elevators as a result, the hall button pressed from among these elevators. If there is more than one elevator waiting or decelerating on the floor where the hall call occurs, when there is a hall call, these The case where the elevator close to the landing button pressed from among the elevators is assigned and made to respond has been described, but the present invention is not limited to this.

That is, for example, in addition to the original group management control function in the group management control device 3, when a hall call is generated, a hall call generation for detecting the floor of the pushed hall button and the position of the hall button is generated. It is determined whether or not there is an elevator waiting or decelerating on the floor of the hall button detected by the processing function and the hall call generation processing function, and as a result, when only one elevator exists. , This elevator is provided with an allocation processing function to control the door opening time of the elevator to be longer than usual only when it is separated from the pushed hall button by a predetermined distance or more, and when a hall call occurs. , If there is only one elevator waiting or decelerating on the floor where the hall call occurred, this elevator is pushed from the landing button. When separated by a distance above but also to control the door-open time of the elevator to longer than usual, in which exactly the same effect as described above can be obtained.

[0028]

As described above, according to the present invention, a plurality of elevators are activated for a plurality of service floors, and an optimum elevator is selected for a common landing call generated in each elevator. -When performing group management control of elevators that are decided and assigned, when there are multiple elevators waiting or decelerating on the floor where the hall call occurs, these elevators Assign an elevator that is close to the landing button pressed from the inside to respond, or if there is only one elevator waiting or decelerating on the floor where the landing call occurred, this elevator is pressed. Since the elevator door opening time is set longer than usual only when the elevator button is separated by a predetermined distance or more, Both can be prevented miss customer, can provide enhanced and other floors group control method and apparatus for highly reliable elevator capable of improving the service to passengers the efficiency of group management control.
