CONSTITUTION:When a landing call button 3 is pushed again at a timing when landing call answer control is approximately completed, it is detected by a reopen detecting part 23 and it is discriminated by a reopen elevator discriminating part 24 at an elevator stop floor to which of landing call input output control parts 41-4n the control part belongs that has a generated a signal. In a case the signal is a landing call signal from a landing call button installed to the side of an elevator under stop, a reopen command is outputted from a reopen control part 25 to a door control unit 5a for an elevator under answer. This constitution causes improvement of a service without lowering of group management control performance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group supervisory control device for operating a plurality of elevators on a plurality of floors and selecting and operating an optimal elevator for a hall call.

[0002]

2. Description of the Related Art In recent years, when a plurality of elevators are installed side by side, in order to improve the operation efficiency of the elevators and the service to the elevator users, an elevator that responds to hall calls on each floor is provided with a microcomputer. Group management control is performed so as to make a rational and prompt allocation using a small computer such as.

That is, when a hall call is generated, the elevator of the optimum car that services the hall call is selected and assigned, and the elevators of other cars are prevented from responding to the hall call.

In the group management control elevator apparatus of such a system, recently, inter-floor traffic volume based on learning data such as measurement of car call registration data and measurement of loading / unloading load data when responding to each hall call in real time And the average time between arrivals at each floor.

Then, the measured data is processed for each time zone based on the above-mentioned measured data, and the demand peculiar to each building is grasped to determine the optimum number of machines when a hall call occurs, when going to work, at lunch, when leaving work. It is directly applied to group management control such as setting of time zone, setting of distributed standby zone during off-peak hours, setting of number of suspended units for energy saving, etc.

In such a situation, after the elevator arrives at the hall call floor in response to the hall call and a certain period of time elapses and the door is being closed, a user who comes later is rushed. There are times when you try to get into the elevator and come up. Also, when a user of the hall presses the hall call button of the hall, if any elevator is waiting on the floor, the elevator will immediately open the door in response to the hall call, The elevator may be located far away from the user who pressed the hall call button.

[0007]

However, in the conventional elevator group management control device, the reopening function by the hall call is disabled for the purpose of maintaining reservation accuracy and efficient operation management. In such a situation, the user may miss the elevator because the door does not open again even if the hall call button is operated while the door is being closed after the hall call is cleared. There was a problem in that the operator had to wait for the arrival of the next assigned elevator by pressing the hall call button again, which would make him wait a long time.

Therefore, as a measure for solving this problem, it is considered that the reopening function by the hall call of the group control elevator is always enabled. In such a case, as described above, There was a problem that the management performance was deteriorated and the group management was not preferable.

The present invention has been made in view of the above-mentioned problems of the related art, and while maintaining the performance of group management control,
It is an object of the present invention to provide a group management control device for elevators that is as easy to use as possible to prevent passengers from getting on board late.

[0010]

According to a first aspect of the present invention, a plurality of elevators are activated for a plurality of floors, an optimum elevator is selected for a hall call, and the selected elevators are called. In the elevator group management control device that controls the hall call response so as to shift to the floor in which the floor call occurred, in the floor where one of the elevators stopped due to the hall call response control, the floor When the floor call button on the floor is operated,
Reopening detection means for detecting the hall call as a reopening request signal, reopening machine discrimination means for discriminating the elevator near the hall call button where the hall call operation is performed, and reopening discrimination means The reopening control means for reopening the door of the elevator is provided only when the elevator responds to the hall call.

According to a second aspect of the present invention, a plurality of elevators are activated for a plurality of floors, an optimum elevator is selected for a hall call, and the selected elevator is set as a floor where a hall call occurs. In the elevator group management control device that controls the hall call response so as to be shifted, in the floor where one of the elevators is stopped by the hall call response control, the hall call button on the floor in the state where the hall call response control is completed When operated, the reopening detecting means for detecting the hall call as a reopening request signal and the elevator door responding to the hall call when the reopening detecting means detects the reopening request signal. It is provided with a half-open reopening control means for reopening to a half-open state.

[0012]

According to the elevator group supervisory control device of the invention of claim 1, in the floor where one of the elevators is stopped by the hall call response control, when the hall call response control is completed, the hall call button of the floor is pressed. When operated,
The reopening detection means detects the hall call as a reopening request signal, and the reopening machine discrimination means discriminates the elevator near the hall call button where the hall call operation is performed, and the reopening discrimination means discriminates The reopening control means for the elevator only when the elevator that has responded to the hall call is
Reopen the door.

Thus, when the elevator stops at the floor call response floor and the door is opened and closed and another user presses the hall call button on the floor when the door is closing, the hall call button The door is reopened only when the installation location is near an elevator that has stopped in response to a hall call, and service is improved without degrading group management control performance.

Further, in the elevator group supervisory control apparatus according to the invention of claim 2, in a floor where one of the elevators is stopped by the hall call response control, the hall call button of the floor is completed in the state where the hall call response control is completed. When is operated, the reopening detection means detects the landing call as a reopening request signal, and when the reopening detection means detects the reopening request signal, the half-open reopening control means responds to the landing call. Reopen the elevator door to the half-open state.

Thus, when the elevator stops at the floor call response floor and the door is opened and closed, and another user presses the hall call button on the floor when the door is closing, the door of the elevator is closed. We will reopen the system to the half-open state to allow other users to get in, and improve the service without degrading the group management control performance.

[0016]

Embodiments of the present invention will now be described in detail with reference to the drawings.

The hall call buttons 3 are installed in the halls on each floor for the number of elevators, and an input / output controller for each button is provided to determine which hall call button the hall call request signal is input from, as described later. Has been. The group management control unit 1, the unit control units 2-1 to 2-N, and the hall call input / output control units 4 are connected via a low-speed transmission line 7 which is a second transmission control means. 5-1
5-N is a door control unit, which is a single control unit 2-1 to 2-1.
The opening / closing control of the door is performed by a command from 2-N.

The high-speed transmission line 6 is a transmission control system for performing transmission between the group management control unit 1 and the unit control units 2-1 to 2-N, that is, mainly between the control computers in the machine room. Connected by a highly intelligent network. Then, the control information necessary for the group management control is transmitted and received at high speed between the group management control unit 1 and the individual unit control units 2-1 to 2-N.

The low-speed transmission line 7 is a control system that mainly transmits information sent through the hoistway, such as the hall call button 3 in each hall, and has a lower speed than the high-speed transmission line 6. , Is composed of an optical cable or the like for a long distance, and is connected to the group management control unit 1 and the unit control units 2-1 to 2-N to exchange data.

When the group management control unit 1 is normal, the hall call button 3 is controlled by the group management control unit 1 via the low-speed transmission line 7, and when the hall call button 3 is pressed, the hall call gate is closed. The registration lamp is set, the optimum machine is determined based on the information data of the single unit control units 2-1 to 2-N sent through the high-speed transmission line 6, and the control command is issued to the single unit. . Then, the unit control unit that receives the control command performs the unit control of its own elevator using the control command as the hall call information. Also, the door control unit 5
Control the opening and closing of the door while inputting and outputting signals to and from -1 to 5-N.

FIG. 2 shows the software system configuration of the group management control unit 1 and the unit control units 2-1 to 2-N. The software consists of operating system (O
The individual control function task, group management control main function task, group management control sub-function task, and transmission control task 9 to 12 are managed by the real-time OS 8 which is S), and each task 9 is managed by the scheduler in the real-time OS 8. ~ 12 are activated or held.

Of these tasks 9 to 12, the unit control function task 9 is a core function of the unit control units 2-1 to 2 -N, controls the opening and closing of the door, and controls each unit control unit 2. Priority is set high as a task for operating -1 to 2-N. The group management control main function task 10 is a central function of the group management control unit 1, and the group management control sub-function task 11 distributed to the individual unit control units 2-1 to 2-N provides information data for each machine. The optimum vehicle number is determined by collecting and performing a comparison calculation, and a control command is issued to the unit control section of the vehicle number and the hall call button 3 is also controlled.

The group management control sub-function task 11 is a function of processing information of each unit of the group management control unit 1, and processes information under the control of the group management control main function task 10. That is, the computer having the group management control main function task 10 manages starting and ending of tasks via the high-speed transmission path 6, and the machine number is issued by a command from the group management control main function task 10 which is a master. The distributed processing is performed in units, and the data is conveyed to the group management control main function task 10 when the processing is completed. The transmission control task 12 controls transmission / reception of data on the high-speed transmission line 6 and activation / termination of the group management control sub-function task 11.

FIG. 3 shows a control function unit in the group management control main function task 10 shown in FIG. As shown in the figure, this task 10 monitors the hall call assignment control task 19 that determines the assigned number when a hall call occurs, and monitors the system status of each unit after the hall call has passed, and permits the reopening function by the hall call. It is configured by a hall call monitoring control task 20 that executes detection and reopen function processing.

FIG. 4 is a characteristic portion of the invention of claim 1,
The functional block diagrams of the hall call assignment control task 19 and hall call monitoring control task 20 of the group management control main function task 10 and the single unit control function task 9 are shown in FIG.
Of the elevator drive system 2a belonging to any of the unit control units 2-1 to 2-N and the door control units 5-1 to 5-N, which drives the elevator of the corresponding car by the hall call response command signal The hall call control unit 21 for performing the hall call response control for the vehicle 5a of the relevant vehicle, and the hall for detecting that the hall call response control by the hall call control unit 21 is completed and the hall call response operation is canceled. The call erasure detection unit 22 and the reopening detection unit that assumes that the reopen command is input when the hall call signal is input again while the hall call erasure detection unit 22 detects the completion of the hall call response. 23 and this reopening detection unit 23
Is detecting the reopening command, the reopening machine discriminating unit 24 that discriminates which elevator car the hall call is input, and the reopening machine discrimination unit 24 is currently calling the floor. When it is detected that the hall call button near the elevator that is stopped in response to the operation is operated, the door opening / closing by the hall call response ends and the closing door is opened again. The reopening control unit 25 is included. Next, the operation of the elevator group supervisory control device having the above configuration will be described.

When a hall call is generated by operating the hall call button 3, the information is sent to the low speed transmission line 7 via the hall call input / output control units 41 to 4n. Then, this information is taken into the group management control main function task 10 by the group management control unit 1, and if any one hall call button 3 of a certain floor is operated, the hall call of that floor is registered. Then, in the group management control unit 1, the hall call assignment control task 19 determines the optimum machine in synchronization with the group management control sub-function task 11 of each single unit control unit 2-1 to 2-N, and goes to the corresponding machine. A hall call is assigned by issuing a control command via the high-speed transmission line 6.

On the other hand, in order to monitor the hall calls that have been assigned, the group supervisory control unit 1 is online via the high-speed transmission line 6 from the individual unit control units 2-1 to 2-N to the elevators. The information is fetched, and the system status monitoring is executed by the hall call monitoring control task 20.

In this hall call response control, in FIG. 4, the hall call control unit 21 operates the elevator drive system 2a and the door control unit 5a in response to the hall call response command being input, and the elevator of the assigned vehicle is controlled. When the hall call button 3 is operated again at the timing when the hall call response control is almost completed, the passenger is put on by opening and closing the hall call generation floor and stopping the door. The reopening control is executed as follows.

As shown in the flow chart of FIG. 5, the hall call erasure detection unit 22 first checks whether or not the hall calls are erased (step S1).
That is, it is checked whether or not the target elevator arrives at the floor where the user is waiting at the hall and the hall call is erased to perform the reopening function in the hall call erased state in which the lantern is blinking.

Then, when it is determined that the hall call is erased, the reopening detector 23 monitors the hall call signal on the elevator stop floor to check whether the hall call button 3 has been pressed (step S2).

Then, when the hall call signal is input, the reopening detection section 23 detects this, and the reopening machine discrimination section 24 determines which hall call button is pressed, that is, the elevator stop floor. It is determined which of the hall call input / output control units 41 to 4n is the signal (step S3), and the hall call button is installed next to the elevator of the stopped machine in response to the hall call of the floor. It is determined from the data set in the ROM 26 as shown in FIG. 6 (step S4), that is, the hall call signal from the hall call button installed beside the stopped elevator. For example, the reopening control unit 25
Outputs a door restart operation command, that is, a reopen command to the door control unit 5a of the elevator that is responding (step S5).

Here, regarding the internal data of the ROM 26 shown in FIG. 6, 1 for each of the hall call input / output control units 41 to 4n corresponding to the number of hall call buttons installed in each floor hall.
~ There is a table that displays up to Unit N (n = N) (here, 8 units of Units A to H), each bit corresponds to each unit, and reopening is permitted. 1 is set to the bit where the button and machine match.
That is, FIG. 6 shows a state in which the hall call button installed near the currently stopped units A and H at the elevator stop floor is pressed.

As a result, one of the elevators of one of the units stops in response to a floor call for a certain floor, and a user who comes later with the door closed near the end of the user's entry and exit When you press the hall call button to get on the elevator with the door closed, when you press the hall call button installed near the elevator that is closing the door, the door is reopened and the user is put on. However, users who have been delayed on the stop floor by disabling reopening when the hall call button installed far away from the elevator that is stopped and the door is closing Because of this, the elevator will not be stopped for a long time, and the users who are near the hall call answering elevator will be reopened. So as to ride on immediately, as much as possible with avoiding the deterioration of the group supervisory control performance of the elevator is to improve the service.

The invention of claim 1 is not limited to the above-mentioned embodiment, and it is possible to reopen only by using the hall call button beside the response elevator, but the size of the hall and the position of the elevator Depending on the situation, the number of landing call buttons that enable reopening can be increased, or conversely, it can be further limited.

Next, in FIG. 7, the hall call assignment control task 19 and the hall call monitoring control task 2 of the above-mentioned group management control main function task 10, which are the characteristic parts of the invention of claim 2, are described.
0 and the functional block diagram of the single unit control function task 9 are shown, but an elevator belonging to any one of the single unit control units 2-1 to 2-N that drives the elevator of the corresponding unit by the hall call response command signal. Drive system 2a, 5-1 to 5
A hall call control unit 2 for performing hall call response control for the relevant vehicle 5b of the N door control units.
1, the hall call erasure detection unit 22 that detects that the hall call response control by the hall call control unit 21 is completed and the hall call response operation is canceled, and the hall call erasure detection unit 22 detects that the hall call response is completed. The reopening detection unit 23 assumes that the reopening command is input when the hall call signal is input again while the reopening detection signal is detected by the reopening detection unit 23. It is composed of a half-open control unit 27 that reopens the door of the inside elevator to a half-open state. In the case of this embodiment, the door control units 5-1 to 5-N have a half-open detection sensor (not shown) for detecting the half-open position of the door (not shown), and when the door is in the half-open state, It shall have an additional function of outputting a detection signal. Next, the operation of the elevator group supervisory control device having the above configuration will be described.

When a hall call is generated by operating the hall call button 3, the information is sent to the low-speed transmission line 7 through the hall call input / output control units 41 to 4n. Then, this information is taken into the group management control main function task 10 by the group management control unit 1, and if any one hall call button 3 of a certain floor is operated, the hall call of that floor is registered. Then, in the group management control unit 1, the hall call assignment control task 19 determines the optimum machine in synchronization with the group management control sub-function task 11 of each single unit control unit 2-1 to 2-N, and goes to the corresponding machine. A hall call is assigned by issuing a control command via the high-speed transmission line 6.

On the other hand, in order to monitor the hall call to which this allocation has been made, the group management control unit 1 is on-line via the high-speed transmission line 6 from each unit control unit 2-1 to 2-N for each elevator. The information is fetched, and the system status monitoring is executed by the hall call monitoring control task 20.

In this hall call response control, as shown in FIG. 7, the hall call control section 21 operates the elevator drive system 2a and the door control unit 5b in response to the hall call response command being input, and the elevator of the assigned vehicle. When the hall call button 3 is operated again at the timing when the hall call response control is almost completed, the passenger is put on by opening and closing the hall call generation floor and stopping the door. The reopening control is executed as follows.

This operation will be described with reference to the flowcharts of FIGS. 5 and 8. The hall call erasure detection unit 22 detects whether or not the hall call erasure state is set (step S1 in FIG. 5), and the hall call erasure is performed. In the case of the state, the hall call signal is monitored to detect whether or not the hall call button is pressed (step S2).

When the hall call button is pressed in the hall call erased state, it is next judged which of the hall call buttons shown in steps S3 and S4 of FIG. 5 is the signal from the hall call input / output control section. Step S without performing the process of detecting the positional relationship between the answering machine and the pressed hall call button.
Step 2 directly jumps to step S5 to output a door open command.

When the door open command is received, the process shown in FIG.
As shown in the flowchart of FIG.
It is detected that the command is a reopening command (step S1
1, S12), and in response thereto, the half-open control unit 27 outputs a reopen command to the door control unit 5b for the elevator that is stopped in response to the hall call at the current floor (step S13), The door control unit 5b reopens the door until it is in the half-opened state, and then closes the door again (steps S15 and S17).

If the door opening command is not the reopening detection signal from the reopening detector 23 in the above step S12, the normal door opening operation is performed, and if the door is fully opened, the door closing operation is performed (steps S14, S16). , S17).

A half-open operation pattern 30 and a full-open operation pattern 31 for reopening by the door control unit described above.
This is as shown in FIG. 9, and a sensor for detecting the half-open position is separately provided for each door, and the door control unit performs the door closing operation again upon receiving the detection signal of the half-open detection sensor. In this way, reopening control is performed.

The invention of claim 2 is not limited to the above-mentioned embodiment, but only in the case where the hall call button near the hall call response elevator is pressed in a form combined with the invention of claim 1. , A half-open reopening operation can be performed. Further, by adding the full-open reopening control unit 28 shown by the one-dot chain line in FIG. 7, when the hall call button is pressed in the hall call response erased state and the half-open reopening operation is performed, the reopening operation is performed. Even in the half-open state, if the hall call button is continuously pressed, the full-open reopening can be performed.

[0046]

As described above, according to the invention of claim 1,
When one of the elevators is stopped by the hall call response control and the hall call response control is completed and the hall call button on the floor is operated, the reopening detection means reopens the hall call. The elevator that is responding to the hall call is detected by the reopening machine discrimination means, which is detected as a request signal, and the elevator near the hall where the hall call button has been operated is discriminated by the reopening machine discrimination means. Only if there is
Since the reopening control means causes the elevator to reopen the door, the elevator stops at the hall call response floor and opens and closes the door, and when the door is about to be closed, another user When the hall call button on the floor is pressed, the door is reopened only when the place where the hall call button is installed is near the elevator that has stopped responding to the hall call, and group management control is performed. It is possible to improve the service without degrading the performance.
