[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for an elevator group management device which, when one of the elevators operating with a plurality of elevators fails, outputs and displays the failed elevator number.

[0002]

2. Description of the Related Art Conventionally, there is a group management device which, when one of a plurality of elevators fails, removes the failed elevator from group management and performs group management control operation on the remaining elevators. FIG.
6 shows a cross section of a landing floor of a conventional group management elevator in which one bank (group) is composed of six elevators and group control is performed. In FIG. 6, 1 is an elevator hall,
2a to 2f are elevator cars, 3 is an operator who repairs a defective elevator, and 4a to 4d are hall buttons for calling a car.

FIG. 7 is a view showing the arrangement of elevators 1 to 3 in the elevator hall 1. In FIG. 7, 51
Numerals 53 to 53 are hall lanterns for displaying the assigned car in response to the car call by the hall buttons 4a and 4b to the user waiting for the arrival of the car 2 in the elevator hall 1. The hall lanterns 51 to 53 correspond to the first to third units, respectively. When the landing button 4 can instruct an upward call or a downward call, for example, the hall lantern 51 for the first car.
In addition, the upper indicator lamp 51 enables the upper and lower indications.
U and a lower indicator lamp 51D are provided.

In the conventional elevator group management system thus constructed, when one of the units fails during the group management operation, the worker 3 operates the landing button 4 to call the car 2 and the elevator 3 Whether or not the car 2 which has arrived in the hall 1 is operating normally from the call registration status of the car 2 on the car operation panel (not shown) in the car 2 and the traveling status of the car 2 Confirm. Then, this confirmation is carried out for the cars 2a to 2f, and as a result of the confirmation, it is specified which unit is the failed unit.

[0005]

As described above, in the conventional elevator group management apparatus, in order to accurately identify the failed car, all the cars 2a to 2f that have arrived at the landing floor have the above-mentioned car Since it is necessary to confirm whether or not the loaded car 2 is operating normally based on the call registration status and the car running status, it will take time and effort especially if the number of units forming the group increases. Instead, there is a possibility that the worker 3 may mistakenly identify the failed machine.

The present invention has been made in order to solve the above-mentioned problems, and eliminates the mistaken identification of the failed unit when one of the elevators forming a group fails. The purpose is to obtain an elevator group control device.

[0007]

According to the elevator group management device of the present invention, when one of a plurality of elevators fails, the failed elevator is removed from group management and the remaining elevators are grouped. In a group management device for an elevator equipped with a group management control device that performs management control, a plurality of failures that are provided corresponding to each elevator and that make contact closure based on the output of the group management control device when an elevator failure occurs A detection switch and a plurality of output means connected to each of the corresponding failure detection switches in series and outputting whether or not there is a failure in the elevator are provided between the power supply terminals.

The output means is provided on a hall lantern provided at the elevator hall.

In addition, between the power supply terminals, a hall button provided at a hall on the reference floor and a time when the hall button is continuously pressed by being connected in series with the hall button are measured, and the measured time reaches a predetermined time limit. Then, the time counting circuit which becomes conductive, and the biasing means which is connected in series with the time counting circuit and is biased when both the hall button and the time counting circuit become conductive are provided and the biasing means is also activated. By doing so, the contact is closed to provide an output control contact for closing the power supply path to each series connection body of the failure detection switch and the output means.

Further, the output means is adapted to output the car position of the failed elevator based on the output of the group management control device.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 is an explanatory diagram of a hall lantern of the elevator group management device according to the first embodiment. FIG.
As a new configuration for the conventional example shown in FIG. 7, 5L is a generic name of 5L1 to 5L6 described later, and, for example, an output display indicating that the machine corresponding to the hall lantern 5 provided in the hall lantern 5 has failed. The output of the failure number indicator lamp is output means, and the surface of the failure number indicator lamp 5L is made of an acrylic plate like the upper indicator lamp 5U and the lower indicator lamp 5D. Here, since the failure number indicator lamp 5L outputs and displays an emergency failure situation, it is desirable that this acrylic plate be colored red transparent, for example.

In addition, since the elevator hall 1 usually does not have a display indicating the number of elevators in terms of design,
During normal operation, elevator users waiting for the arrival of car 2 in elevator hall 1 do not know the elevator number. Therefore, in order to make it easy for the worker 3 in the elevator hall 1 to know which unit has failed when the elevator is out of order, the acrylic plate is provided with contrasting shades so that the failed unit (number) can be displayed. Is formed, and as will be described later, when the lamp is lit, the number is lit and displayed. The same applies to the failure unit indicator lights related to elevators Units 2 to 6.

FIG. 2 shows a lighting circuit of a failure number indicator lamp of the elevator group management system according to the first embodiment. FIG.
Between the power supply terminals, for example, in the case of A1, the elevator of No. 1 machine fails, and when the group management control device (not shown) removes the elevator of No. 1 machine from the control target of the group management operation, it closes based on the output of the group management control device. It is a contact point of a failure detection relay that serves as a failure detection switch. A reference numeral 5L1 is a failure unit indicator lamp which is an output means for displaying the number "1" when the elevator of the first unit fails. And
The contact A1 of the failure detection relay and the failure number indicator lamp 5L1 are connected in series as shown in FIG. 2 to form a series connection body. The contact points A2 to A6 of the failure detection relay and the failure unit indicator lights 5L2 to 5L6 are also provided corresponding to the elevator machines of the 2 to 6 units, respectively, and when each elevator fails, the contact point A1 of the failure detection relay. And a contact point of a failure detection relay and a failure number indicator lamp that perform the same operation as the failure number indicator lamp 5L1. Failure detection relay contacts A1 to A6 and failure machine display lamps 5L1 to 5L
A series connection with 6 is formed for each car, and the series connections are connected in parallel and provided between the power supply terminals.

The operation of the lighting circuit for the fault indicator lamp of the elevator group management device thus constructed will be described with reference to FIGS. In FIG. 2, during normal operation in which there is no failed unit in the elevator group, the signal indicating that none of the elevators has been excluded from the control target of the group management operation is not output from the group management control device, so the failure detection relay All the contacts A1 to A6 are OFF, and none of the failure number indicator lamps 5L1 to 5L6 are lit and displayed.

Here, for example, when the elevator of No. 1 machine breaks down, the group management control device excludes the elevator of No. 1 machine from the control target of the group management operation. Then, the failure operation detection relay A1 is closed based on the signal output indicating that the first unit is excluded from the control object of the group management operation from the group management control device,
A voltage is applied to the failure number indicator lamp 5L1 to light it. As a result, the machine number "1" is lit and displayed on the hall lantern of FIG. 1 through the acrylic plate.

As described above, in the circuit shown in FIG. 2, when one of the elevators of Units 1 to 6 for Hall lanterns 51 to 56 fails, the circuit of the elevator that has failed is based on the output of the group management control device. The corresponding failure machine indicator lights 5L1 to 5L6 are lit and displayed.

Therefore, according to the first embodiment, when one of the plurality of elevators fails, the failed elevator is removed from the group management and the remaining elevators are subjected to group management control. In the elevator group management device equipped with a control device,
Failure detection switches A1 to A6 provided corresponding to each elevator and closing contacts based on the output of the group management control device when a failure of the elevator occurs, and serially connected to the corresponding failure detection switches A1 to A6, respectively. No. 5L1-5, which are installed in the hall lanterns 51-56 that are connected to the vehicle and output whether or not there is an elevator failure
Since L6 is provided between the power supply terminals, the failed unit is the failed unit indicator light 5L of the hall lanterns 51 to 56 at the hall.
Since it is lit and displayed in 1 to 5L6, it is possible to easily confirm the failed machine number for each machine, and there is no specific error of the failed machine number. In addition, since the failed machine can be immediately determined, the worker 3 can promptly deal with the failure recovery work.

Embodiment 2. In the first embodiment, when any of the units fails, the defective unit indicator light of the failed unit lights up, so the elevator is used even though the failed unit is excluded from the control targets of the group management operation. There is a case in which the use efficiency of the elevator is lowered because the person evades the use of the elevator by illusion that any one of the failure number indicator lights 5L1 to 5L6 is lit and the entire group of elevators is out of order. Since it is sufficient for the rushing worker 3 to know that there is a defective elevator machine, Embodiment 2 shows an example of an elevator failure machine indicator that eliminates such a decrease in elevator utilization efficiency.

FIG. 3 shows a lighting circuit of a failure machine indicator lamp of the elevator group management system according to the second embodiment. FIG.
In the middle and between the power supply terminals, as a new configuration to the first embodiment shown in FIG. 2, C1 is a landing button on a reference floor (for example, the first floor), and T1 is a landing button C1 is continuously pressed and the voltage is changed.

They are connected in parallel and provided between the power supply terminals.

Further, B2 is a failure number indicator lamp 5L1 to 5L
6 is a contact of the time detection relay B1 provided between the power supply terminal shared by 6 and the power supply terminal of the time detection relay B1 and serving as an output control contact that is closed when the time detection relay B1 is energized. Here, B2 is a power supply terminal shared by the contacts A1 to A6 of the failure detection relay and a landing button C.
It may be provided between one power supply terminal.

The operation of the lighting circuit of the failure number indicator lamp of the elevator group management device thus constructed will be described with reference to FIG. In FIG. 3, during normal operation in which no failed unit exists in the elevator group, the signal indicating that none of the elevators has been excluded from the control target of the group management operation is not output from the group management control device, so the failure detection relay All the contacts A1 to A6 are OFF, and none of the failure number indicator lamps 5L1 to 5L6 is turned on.

Here, for example, if the elevator of No. 2 machine breaks down, the group supervisory control device removes the elevator of No. 2 machine from the control target of the group supervisory operation. Then, the faulty operation detection relay A2 is closed based on the signal output from the group supervisory control device indicating that Unit 2 has been excluded from the control target of the group supervisory operation. At this stage, none of the faulty machine indicator lights 5L1 to 5L6 is turned on.

The worker 3 who has come to the repair continues to press the landing button C1 on the reference floor (first floor) for a predetermined time (30 seconds) or more in order to specify which elevator has failed. As a result, the hall button C1 and the time limit counter circuit T1 are in a conductive state, that is, a state in which the time for which the voltage is applied is measured, and the time limit detection is performed because the voltage is applied to the time limit counter circuit T1 for a predetermined time (30 seconds) or more. The relay B1 is energized and the contact B2 is also closed. Therefore, the failure unit indicator light 5L
2 is turned on when a voltage is applied. As a result, the machine number "2" is lit and displayed on the hall lantern via the acrylic plate.

In this way, the failure number indicator lights 5L1 to 5L
6 indicates that when one of the elevators fails and one of the elevator failure detection relay contacts A1 to A6 is closed, and the worker 3 who has come to repair has pressed the hall button C1 on the reference floor to 3
Only when the time counter circuit T1 is turned on by pressing for more than 0 second and the time detection relay B1 is energized and the contact B2 is closed, the light is turned on.

Therefore, according to the second embodiment, the hall button C1 provided at the hall on the reference floor between the power supply terminals.

1 and the time detection relay B1 is energized to close the contacts, thereby making contact points A1 to A of the failure detection relay.
6 and the contact number B2 of the time detection relay B1 that closes the power supply path to each series connection body of the failure number indicator lights 5L1 to 5L6
Since the failure number indicator lights 5L1 to 5L6 are equipped with, and one of the elevator failure detection relay contacts A1 to A6 is closed due to the failure of one of the elevators, and the landing button C1 on the standard floor is pressed for 30 seconds or more. Time counter circuit T1
Becomes conductive, the time detection relay B1 is energized and lights only when the contact B2 is closed. Therefore, it is possible to prevent the user from being aware that one of the elevators has failed and to improve the efficiency of elevator use. You can get an elevator that eliminates the drop.

Embodiment 3 In the first embodiment, it is possible to identify which is the failed unit, but since it is not known in which floor the car of the failed elevator is stopped, it is possible to determine in which floor the car is stopped. If known, the worker 3 is convenient for repair work.

FIG. 4 is a circuit diagram for lighting a failure number indicator lamp of the elevator group management system according to the third embodiment. FIG.

It is a car position display section. The car position display portion D1 is provided in place of the elevator failure detection relay contact A1 and has a known technique. In the first embodiment, the number of the failed unit is displayed, but in the third embodiment, the car position of the failed elevator, that is, the car floor is displayed. Therefore, the car position display portion D1 includes, for example, a digital liquid crystal display portion.

Further, the contact A1 of the failure detection relay and the car position display portion D1 are connected in series as shown in FIG. 4 to form a series connection body. Failure detection relay contact A2

Thus, the series connection body of the contacts A1 to A6 of the failure detection relay and the car position display portions D1 to D6 is configured for each car, and these series connection bodies are connected in parallel and provided between the power supply terminals. .

Regarding the operation of the lighting circuit of the failure number indicator lamp of the elevator group control device thus configured, FIG.
It will be described based on. In FIG. 4, during normal operation of the elevator, the group management control device does not output a signal indicating that none of the elevators is controlled by the group management operation. Therefore, all the contacts A1 to A6 of the failure detection relay are O.
The floor position is not displayed on the car position display portions D1 to D6.

Here, for example, if the elevator of No. 1 machine breaks down, the group management control device removes the elevator of No. 1 machine from the control target of the group management operation. Then, the failure operation detection relay A1 is closed based on the signal indicating that the first unit output from the group management control device is excluded from the control target of the group management operation, and the car of the first unit output from the group management control unit is closed. Based on the car floor signal, the car position display portion D1 displays the car position of the faulty elevator.

As described above, in the circuit shown in FIG. 4, when one of the elevators of Nos. 1 to 6 fails, the car position display unit corresponding to the failed elevator's No. is based on the output of the group management control device. The car position of the car is displayed on D1 to D6.

Therefore, according to the third embodiment, the car position display portions D1 to D6 are designed to output the car position of the failed elevator based on the output of the group management control device. Confirmation can be done easily for each machine,
There is no specific error in the failed unit. Further, since the failed unit and its car position can be immediately determined, the worker 3 can quickly perform the failure recovery work.

As a result, the hall button C1 and the time limit counter circuit T1 are in a conductive state, that is, a state in which the time for which the voltage is applied is measured, and the time limit detection is performed because the voltage is applied to the time limit counter circuit T1 for a predetermined time (30 seconds) or more. The relay B1 is energized and the contact B2 is also closed. Therefore, the car position display portion D1
When a voltage is applied to the car, the car position display section D1 outputs and displays the car position of the failed unit 1 elevator based on the output of the car position signal of the group supervisory control device.
