Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a case where an old group management elevator is replaced with a group management elevator having a different design and a new function (hereinafter referred to as "linear"). The present invention relates to a group management elevator linear method to be applied.

[Conventional technology]

Heretofore, as this type of linear method, there has been a divided linear method in which all units are replaced by performing several operations while replacing each unit.

[Problems to be solved by the invention]

In the above-mentioned prior art, there is a period in which new and old elevators coexist and operate. At this time, the group control operation cannot be performed because the control methods of the new and old elevators are different, and the operation efficiency of the elevator is very poor. In addition, in order to perform the group management operation, an interface was required to dock the signal control systems of the new and old elevators, which required death, resulting in remodeling work, which was very expensive.

An object of the present invention is to solve the above-described problems, and to improve the operating efficiency of an elevator during a period in which new and old elevators are mixed and operated, further eliminating the need for an interface and reducing cost. To provide a linear method of group management elevator.

[Means for solving the problem]

The above object is to invalidate a part of the floor of the hall call response circuit of the old elevator, and furthermore, in the new elevator, to call only the floor where the hall call response circuit of the old elevator is invalidated. This is achieved by configuring a response circuit.

[Action]

The old elevator responds and operates only when a hall call occurs in its own hall call service zone. If a hall call that is not the hall call service zone of the old elevator occurs, the new elevator responds and operates because the new elevator is in charge of the hall call service zone of this zone. In this way, the new and old elevators respond and operate only when a hall call occurs in their own hall call service zone, so that the old and new elevators do not respond simultaneously to one hall call, which is efficient. Can drive. In addition, even when several new and old elevators are mixed, the existing group management circuit is effective because the old elevators have the same control. In addition, since the same control is performed between new elevators, the new group management circuit can be made effective, thereby enabling efficient operation. Furthermore, since both the old and new elevators can be dealt with by invalidating the hall call response circuit of the own control circuit, docking of the signal control system of the old and new elevators becomes unnecessary, and the cost is low because no interface is required.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a flow chart showing a typical process of linearly operating three group control elevators. The process is roughly divided into four stages, A, B, C, and D. The control state of each elevator at each stage is shown in column (a),
The operating state is shown in column (b). In the A stage, the operation of Unit 1 is suspended and linear works are performed. 2,3 during this time
Unit No. is operating in the old group management operation under the old control. B
At the stage, Unit 1 has completed the linear construction and is operating under the new control. Unit 2 will be out of operation and will be rehabilitated. Unit 3 is operating under the old control. At this time, the hall call service zone is divided into the first unit under the new control and the third unit under the old control to operate. At the C stage, the second unit has also completed the linear construction and is operating under the new control. Therefore, the new control units 1 and 2 can operate with the new group management operation. At this time, the Unit 3 suspends operation and performs linear construction.
At the D stage, the linear construction of Units 1, 2, and 3 was completed,
It operates with the new control operation of three new groups.

Next, referring to FIG. 2, a description will be given of an operation method during a period in which new and old controlled elevators coexist and operate. 11,21,31 are the first, second and third cars. 1AU to 5AU is an up hall call button installed on the A row side from the 1st floor to the 5th floor,
2AD to 6AD are down hall call buttons installed on the A row side from the 2nd to 6th floor, 1BU to 5BU are up hall call buttons installed on the 1st to 5th floor row B side, 2BD to 6BD is 2
This is a down hall call button installed on the side of row B from the sixth floor to the sixth floor. In general, at least two sets of three or more group control elevators are installed on each floor. In FIG. 2, row A is used as a hall call button for the first car and row B is used as a hall call button for the third car. This is an example used.

The first unit shows a state in which the linear construction has been completed, and is operated by the new control panel 13 and the new group management panel 12 under the new control. 2
Unit No. shows a state of being under linear construction and is in a suspended state. For this reason, the old control panel 23 for the second unit is in an electrically disconnected state. Unit 3 is in a state before the linear construction, and is operating under the old control by the old control panel 33 and the old group control panel 32. Hall call button, 1AU-3AU and 2A
D to 4AD indicate a state in which they are connected to the new group management panel 12, and when these hall calls are registered, the first car is operated. 4AU, 5AU and 5AD, 6
Since the AD is not connected to the new group management panel 12, these hall call buttons are disabled, and the first car is not operated.

The hall call buttons, 1BU, 4BU, 5BU and 5BD, 6BD show the state where they are connected to the old group management panel 32, and when these hall calls are registered, the third unit is operated. I have. Since 2BU, 3BU and 2BD to 4BD are not connected to the old group management panel 32, these hall call buttons are disabled and the third car is not operated.

In FIG. 2, since the first floor is set as a reference floor where there are many elevator users, both the first and third units respond to the first floor landing call buttons 1AU and 1BU.

In FIG. 2, the floors that do not provide service for the hall call button are not connected to the new group management panel and the old group management board, respectively. It is easy to connect to the group control panel and the old group control panel, and to respond by changing some circuits in each group control panel. In this way, the service floor can be easily divided, and the new control elevator No. 1 and the old control elevator No. 3 can be operated efficiently because they service different landing call buttons.

〔The invention's effect〕

According to the present invention, the new control elevator and the old control elevator do not simultaneously respond to the divided landing call, so that the operation efficiency of the elevator is improved. In addition, since signal transmission between the old control elevator and the new control elevator is not required, an interface is not required and the cost is low.
