Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a building having a large demand for elevators, and in the case where there is too much demand for the elevators under group management control, the elevators in the building are organically linked to transport capacity. The present invention relates to an elevator device capable of improving the above.

[Technical background of the invention and its problems]

In recent years, when multiple elevators are installed side by side, in order to improve the operating efficiency of the elevators and to improve the service to users, a response machine to the hall call in the hall on each floor uses a small computer such as a microcomputer. Allocation is done reasonably and promptly.
This is a control method called group management control.When a hall call occurs, an elevator that is most suitable for handling the hall call is selected, and the hall call is responded to at an early stage, while the other elevators are not affected by the hall call. Do not answer the call, or when you go to work or leave the morning,
For efficient operation while switching to a preset operation mode according to the traffic changes unique to the building, such as during heavy traffic demand such as during lunch, or when traffic decreases such as at night. It controls each elevator.

On the other hand, in large office buildings in recent years, the number of elevators tends to be reduced as much as possible in order to increase the effective floor area ratio.

As a result, congestion becomes severe at the morning up peak, which is the peak of elevator transportation, both the up and down peaks during lunch, and the down peak in the evening.

Generally, in large buildings, group management is controlled 4
In addition to the group of 8 elevators, it is customary to install several elevators for backpacking (for passengers) used for transportation of goods and the like. Also, because of the nature of its use, this elevator is
It is common to service all floors.

However, these back elevators have little to do with the customer elevators that are under group supervision and therefore have little utility in increasing transport efficiency at peak demand.

[Object of the Invention]

The present invention has been made in view of the above circumstances, and its purpose is to operate an elevator under group management control and an elevator for passengers behind it in an organically linked manner during high demand for elevators. An object of the present invention is to provide an elevator device that is designed to improve transportation efficiency.

[Outline of Invention]

In order to achieve the above object, the present invention, in an elevator apparatus of a building in which an elevator group placed under group management control and an elevator performing an independent operation are installed in parallel, group management control for each elevator placed under group management control. A group control device for performing operation and an independent control device for operation control of an elevator that performs an islanding operation are connected for information transmission, and the group control device has a determination function for determining a set high traffic demand. When it is determined that there is a traffic demand, an interlocking operation command is generated and given to the individual control device, and a function of performing control by targeting the group management control is provided, and when the above single unit control device receives the interlocking operation command, The above-mentioned group control device is provided with a function of performing operation control of the elevator under group management control.

In other words, this device has conventionally been operated to increase the maximum efficiency only with the elevators in the bank in the group management control elevators in the building. When the demand for elevators is high, this elevator for passengers is put under group management control to operate in tandem, and all elevators in the building are managed organically. To deal with peak demand.

As a result, when the demand for elevators is high, it becomes possible to operate all the elevators in the building under group control and organically operate, and it is possible to dramatically improve transport efficiency and service to users. In addition to the above, since it is possible to control an elevator for island operation by group management when demand is high, a bank is constructed with a number of elevators that takes into account normal intra-building traffic demand, and normal group management control is performed. Even if the number of elevators is kept to a minimum, it is possible to sufficiently meet the peak demand, which makes it possible to keep the number of installed elevators small and not only to effectively use the building space, but also to Make it possible to reduce equipment costs.

Example of Invention

The feature of this device is that the single elevator control panel for the passengers in the back, which is not normally under the group management control, is connected to the common panel for the group management control, and these elevators for the passengers are always group management controlled. When the elevator for passengers is placed under the group management control, the guide display device provided in the hall can display that the elevator for passengers can be used to guide the passengers. There is a point.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an apparatus according to the present invention. Here, an example is described in which one bank of elevator groups managed by a group is one bank and two elevators for passengers are two groups. . In the figure, 1 is a common board for group management control,
2A, 2N, 2X, 2Y are unit control panels provided for each elevator. This unit control panel 2A, 2N, 2X, 2Y selects the direction according to the car position in order to service it according to the registered car call information and assigned hall call information, and applies the lifting direction command and operation pattern. It controls the deceleration control, the door opening / closing control when the service floor is stopped, and other controls required for single elevator operation. Further, 3,3X, 3Y are hall call buttons for up and down directions provided in the hall for calling the hall, 4 are hall indicator lights for hall waiting guide information provided in the hall, and 5A, to 5N , 5X, 5Y are cages of elevators for the A to N and X and Y elevators.

The above unit control panels 2A, ~ 2N, 2X, 2Y are available for elevators from Units A to N and Units X, Y, and the subscripts A, ~ N, X, Y are attached according to each unit. Shall be distinguished. Also, the X and Y elevators have their own hall call buttons 3X and 3Y, respectively. To use the X and Y elevators during normal operation, operate the respective hall call buttons 3X and 3Y. It is necessary to call the hall. Therefore, in the X and Y elevators, the hall call buttons 3
By operating X and 3Y, the hall call is normally registered in each unit control panel 2X and 2Y, and unit control is performed to respond to the registered hall call. Also,
Normally, the common board 1 responds to hall calls generated by the hall call buttons 3, and targets the elevators from Units A to N. The running state of each unit (whether decelerating, accelerating, steady running, or not) In addition, if it is stopped, information such as whether the door is open or closed), and currently assigned to hall calls and car calls, and registered information such as service floors can be obtained from each unit control panel 2A, 2N. Then, a predetermined evaluation calculation is performed, and from the result, an optimum No. which can respond earliest to the generated hall call is selected, and the generated hall call is assigned to the single control panel of the selected No.

In addition, in this system, the unit control boards 2X and 2Y are connected to the common board 1 by the control line e so that the passenger elevators X and Y are also under the group management control during the time when the demand for the elevators is high. It is also possible to perform group management control.

In addition, a is a group control signal line for group control signal transmission that connects the single control panels 2A, 2N and the common control panel 1, and b is a hall call signal transmission that connects the hall call button 3 and the common control panel 1 described above. Hall signal line, c is a hall indicator light signal line for transmitting the hall indicator signal connecting the hall indicator lamp 4 and the common control panel 1, and d is each single control panel 2A, ~ 2N, 2X, 2Y Corresponding basket 5A, ~ 5N, 5X, 5Y
It is a car signal line for car signal transmission that connects with.

The features of this device are that the common board 1 and the hall indicator light 4 are connected by the indicator light signal line c, and the elevators of the X and Y elevators, which are the elevators for passengers in the back, which are not under the group management control. The single control panels 2X and 2Y are connected to the common panel 1 by the control signal line e so that the elevators of these X and Y units can be under the group management control at any time.

The landing indicator light 4 is for guiding the passengers to the elevator for passengers. For example, the display as shown in FIG. 2 can be performed by lighting the lamps. Of course, this is an example, and the display content and display means are not limited to this.

Fig. 5 is a diagram showing an elevator layout in the building 6, where 7 is a bank elevator for customers (elevator under group control), and 8 is a single elevator for passengers (outside group control). Elevator). The passenger elevator 8 is arranged behind the passenger elevator 7 behind.

Applying the elevator having such an arrangement to the configuration of FIG. 1,
The organic connection enhances the elevator utilization efficiency throughout the building.

Next, the operation of the present apparatus having the above configuration will be described with reference to the flowcharts of FIGS. 3 and 4.

FIG. 3 is a flow chart for explaining the operation of the common panel 1, and FIG. 4 is a single control panel 2X, 2 for the passenger elevator.
7 is a flowchart for explaining the action of Y. First, the operation of the common board 1 will be described with reference to FIG.

FIGS. 3 (a) and 3 (d) show a method for detecting the degree of congestion, and FIGS. 3 (a) and 3 (c) show a group management operation pattern during an up-peak time that occurs during work hours in the morning. Shows the processing of.

First, in FIG. 3 (a), during normal group management control execution,
For example, when an up-peak is detected on the common panel 1 from information such as a new-occurrence hall call, a new-occurrence car call, or fullness, an interlocking operation command output is immediately issued to the single control panels 2X and 2Y that are not under group management. As a result, the stand-alone control panels 2X and 2Y will operate in tandem,
It will come under group management control.

FIG. 3 (b) is a diagram in which the set time zone determination function is added to the above (a). By knowing the time by the clock device built in the common board 1, it is known that the preset high demand time zone has been entered. Then, the up-peak inrush determination is performed for the first time, and the interlocking operation command is given to perform the interlocking operation. Further, in FIG. 3C, the changeover switch further forces the function of FIG. It shows a case where the operation can be switched to the interlocking operation so that the interlocking operation can be performed at an arbitrary time. In addition, FIG. 3 (d) is a system in which the standby floor at the time of interlocking operation for the unit control panels 2X, 2Y outside the group management control can be specified in addition to the method of (c) above. Not only for up-peak operation, but for down-peak operation, lunch operation, etc., by setting the most congested floor as the standby floor, it is possible to centrally service the interlocked operation machine on the congested floor. It was done.

Of these various procedures, it is executed by using an appropriate one, and by commanding the interlocked operation to the single control panel 2X, 2Y of the passenger elevator according to the demand during the normal group management control, When crowded, keep passenger elevators under group control.

FIG. 4 is a flow chart showing the operation of the single elevator control panels 2X and 2Y of the passenger elevator in the interlocking operation mode.

In FIG. 4 (a), when the interlocking operation command is received, the stand-alone control panel does not perform the pause or the dedicated operation, and it is determined that the operation is in the normal operation. After issuing a command to return the own car to the standard floor, a display command for the hall indicator light 4 is generated, and the hall indicator light 4 displays as shown in FIG. It is displayed on the screen to inform the waiting customers.

Further, (b) is a case where a designated waiting floor is designated in response to the standard floor return command in FIG. 4 (a). In this case, designated waiting floor is selected and the designated floor waiting operation is performed. By issuing a command, the car is moved to the designated waiting floor, and then the hall indicator light 4 is displayed to display in the hall that the interlocking operation has been started to notify the hall waiting passengers. This is an example of control in a single control panel when the procedure of FIG. 3 (d) is followed.

In this way, in normal times, independent control is performed by disconnecting the passenger elevator from the group management control elevator, and when the common panel 1 issues an interlocking operation command during a specific time period, high demand, etc. Upon receipt of this, the elevator for use returns to the standard floor or moves to the designated floor, and then enters the group management control by the common board 1. When entering the group management control, hall calls generated by the hall call buttons 3, 3X, 3Y are sent to the common panel 1, and information such as elevator floor status information, etc. that has already been registered such as car call registration for each elevator is displayed. With reference to the evaluation calculation, the optimum number of serviceable hall calls for all elevators under group management control is determined, and the hall calls are assigned to the determined number. This allows the assigned elevator to service its floor.

If the demand peaks, the set time period passes, or if the forced interlocking operation is canceled in the case of the forced interlocking operation mode, the elevator for passengers is released from the interlocking operation and returns to the independent operation.

In this way, this device has conventionally been operated in a group supervisory control elevator in a building so as to increase the maximum efficiency only by the elevator in the bank, so it is usually installed in a large building. The use efficiency of the passenger elevators in the above was ignored, so that the elevators for passengers can be operated under the group management control when the elevator demand is high, and all elevators in the building can be operated organically. It was managed to handle peak demand.

As a result, when the demand for elevators is high, it becomes possible to organically operate all the elevators in the building under group management control, and it is possible to dramatically improve transportation efficiency and service to users. In addition, the elevator for single operation can be controlled by group management when demand is high, so a bank is constructed with the number of elevators considering normal intra-building traffic demand and normal group management control is performed. Even if the number of elevators is kept to a minimum, it will be possible to adequately meet the peak demand, so it will be possible to keep the number of installed elevators small and not only to effectively use the space of the building, but also the equipment cost of the elevators. Can be reduced.

The present invention is not limited to the embodiments described above and shown in the drawings, and it is needless to say that the present invention can be appropriately modified and carried out within the scope of not changing the gist of the invention. The control has been described for the case of one bank, but this is also applicable to a configuration of a plurality of banks, and the number of elevators such as elevators for passengers that are not normally placed under group management control does not matter. Further, the display of the hall indicator light may be anything as long as it is in accordance with the contents to be guided, and the number of installed places and the place may be set as necessary.

〔The invention's effect〕

As described above in detail, according to the present invention, it becomes possible to dramatically improve the transportation efficiency and the service to users, and to control the elevator for island operation by group management when the demand is high. Therefore, even if the bank is configured with the number of elevators that takes into account the normal intra-building traffic demand and the number of ordinary group management control elevators is kept to the minimum, the peak demand can be sufficiently met. Therefore, the number of installed elevators can be suppressed to a small number, and not only can the space of the building be effectively utilized, but also the equipment cost of the elevator can be reduced, etc. You can do it.
