Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to improvements in group management operation.

[Conventional technology]

Figure 2 is based on, for example, a conventional door control device by operating a door opening time extension button shown in Japanese Patent Publication No. 61-269 and a conventional landing call registration device shown in Japanese Utility Model Publication No. 50-68470. This figure shows the circuit diagram when operating the door opening time extension button configured with 2 units (F
This is an example of an elevator (denoted as No. 1 and No. G). In the figure, (+) and (-) are DC power supplies, 1 is a hall button, 1A is a hall call registration relay, 1Aa and 1Ab are their normally open contacts, 1B is a response lamp, 1Ca is a response relay contact, and 2 is the door opening time extension button of Unit F (hereinafter simply referred to as the opening extension button), 2A
is the open extension button operation relay of the F machine, and 2Aa is its normally open contact. 2B is the time limit relay of the F machine that operates after a certain period of time (for example, 2 minutes) when energized, and 2Ba is its normally closed contact. , 3 is the opening extension button of the G machine, 3A is the opening extension button operation relay of the G machine, and 3Aa is its normally open contact. It is a time relay, and 3Ba is its normally closed contact, 4 is a group of conditional contacts that determine whether or not it is within the group control of the F machine, 4A is the group control detection relay for the F machine, and 4Aa is its normally open contact. Contact point 5 is a condition contact group that determines whether Unit G is within group control, 5A
is the group control internal detection relay of machine F, and 5Aa is its normally open contact.

Next, the operation will be explained. When the open extension button 2 of the F machine is operated, the F machine's open extension button operation relay 2A is energized by the (+)-2-2A-(-) circuit, and its contact 2Aa is closed to maintain self-holding. At the same time, the door of the F machine is maintained in the open state by the door control device (not shown) of the F machine. On the other hand, the time limit relay 2B of the F car starts counting the time limit from the time when the opening extension button 2 of the F car is operated. As, when the count for a certain time period (for example, 2 minutes) expires,
The normally closed contact of timed relay 2B of Unit F opens, and F
The opening extension button operation relay 2A of the No. 1 car is deenergized, and the door of the No. F car is released from the open state by the door control device (not shown) and returns to the normal operating state. Incidentally, when the opening extension button 3 of the G car is operated, the operation is similar to that of the F car, so the explanation will be omitted.

As mentioned above, when the extension button is operated,
The opening extension button operation is performed at each predetermined time without any involvement in group management operation.

[Problem that the invention seeks to solve]

The operation device for the conventional elevator opening/extension button operation is configured as described above, so in the case of group management operation, when allocating common hall calls, the There were problems such as the inability to change assignments and the inability to respond to calls to the hall, resulting in a significant drop in service.

This invention was made to solve the above problems, and when the opening extension button is operated,
An object of the present invention is to obtain an elevator operating device capable of preventing deterioration of service for passengers in a hall.

[Means for solving problems]

The elevator operating device according to the present invention temporarily excludes elevators whose opening extension button has been operated from group control, and when the opening extension button has been operated on all elevators, excludes operation of the opening extension button in the near future. In order to return to the group control state, the system maintains the group control operating state and disables the hall call registration restraint means.

[Effect]

The elevator operation device of this invention assumes that the operation of the opening extension button is temporary, so when there is one or more elevators, only the relevant elevator is temporarily out of control, and when all elevators are operated, it is placed in a common landing area as within the control. By keeping the call registration valid, this prevents the deterioration of service to passengers at the landing and allows for appropriate group management operation.

[Embodiments of the invention]

Hereinafter, two examples of this invention (F machine, G machine) are shown.
This will be explained using an example of an elevator.
In Figure 1, 2C is the open extension button operation detection relay of machine F, 2Ca is its normally closed contact, and 3C
is the open extension button operation detection relay of machine G, and is 3
Ca is its normally closed contact, 6 is the two open extension button operating relays for machines F and G, and 6a and 6b are their normally open contacts.

In a circuit configured in this way, if, for example, the open extension button 2 is operated only on machine F, (+) -
The open extension button operation relay 2A of the F machine is energized by the circuit 2-2A-(-), its normally open contact 2Ab is closed, and the open extension button operation detection relay 2C of the F machine is activated (+)-2Ab-. 2C-(-) circuit, its normally closed contact 2Ca is opened, and the group control inside detection relay 4A of the F car is deenergized, so the F car is excluded from the group control operation. At this time, if a common landing call has already been assigned by the group control device (not shown), an allocation change signal (not shown) is sent to cancel the allocation for car F and to add additional allocation to car G. It will continue to provide service for hall calls in place of Aircraft F.

In addition, when machines F and G are operated at the same time, the normally closed contacts 2Ca and 3Ca are opened by the activation of the open extension button operation detection relays 2C and 3C.
By energizing the two open extension button operation relays 6 and closing their normally open contacts 6a and 6b, the group control detection relays 4A and 5A of the F and G cars remain energized. As a result, the normally open contacts 4Aa and 5Aa also remain closed, and the hall call registration circuit is maintained in the valid state.

In the above embodiment, an explanation has been given of the opening extension button, but other devices for maintaining the door open state (for example, an opening extension switch) may be used, and the same effects as in the above embodiment can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, when the elevator opening extension button is activated for one or more elevators, only the elevator in question is temporarily out of control and a support operation is performed, and when all elevators are in operation, it is considered to be under control and a common platform is used. Since the system is configured to enable call registration, it has the effect of preventing deterioration of service for passengers at the boarding point.
