[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for renewing an elevator in which a large number of elevators are installed side by side so as to perform control operation.

[0002]

2. Description of the Related Art Conventionally, when renewing a group-controlled elevator in which a large number of vehicles are installed side by side, one group or a plurality of groups is sequentially reconstructed. The state that the elevator group is installed at the same time occurs. However, the control operation command signal issued from the elevator monitoring panel is 1
There is one signal per group management elevator for the group. Therefore, in order to control the elevator group after the renewal control operation, it is necessary to supply the control operation command signal from the elevator group before the renewal to the elevator group after the renewal.

[0003]

However, in the conventional elevator renewal method, the elevator control panel before renewal is provided in order to supply the control operation command signal from the pre-renewal elevator group to the post-renewal elevator group as described above. Had to make a circuit change. Also, since all the old control panels will be removed during the final renewal work, it was necessary to change the circuit configuration so that the new control panel after the renewal would receive control operation command signals. At this time, changing the circuit inside the old control panel is poor in workability, and when removing the old control panel, the signal line for control operation, which must be changed to the new control panel, is accidentally cut and the necessary line is removed. There was also the danger of becoming unknown.

An object of the present invention is to provide an elevator renewal method that facilitates renewal work.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a plurality of elevators arranged in parallel so that a control operation is performed via an elevator control panel by a control operation command signal issued from an elevator monitoring panel. In the renewal method of (1), an elevator control panel after renewal having a control operation circuit that operates in response to the control operation command signal to perform the control operation of the elevator group after the renewal is provided, and the elevator control panel after the renewal and before the renewal The elevator control panel is connected and the control operation circuit in the elevator control panel before the renewal is operated through the control operation circuit to perform the control operation of the elevator group before the renewal, and during the renewal period. In addition, the elevator group before the renewal and the elevator after the renewal Characterized in that so as to commission the data group at the same time.

[0006]

In the elevator renewal method according to the present invention, as described above, since the control operation circuit that operates by the control operation command signal from the elevator monitoring panel is provided in the elevator control panel of the elevator group after the renewal,
First, the control operation start signal can be input to the elevator control panel after renewal, and then the control operation command signal can be supplied to the elevator control panel before renewal via the control operation circuit of the elevator control panel after renewal. , Even if the connection with the elevator control panel after renewal is released to remove the old elevator control panel before renewal, the connection between the elevator monitoring panel and the elevator control panel after renewal is maintained, and the elevator group after renewal The renewal work can be facilitated without affecting the control operation of.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a wiring diagram of a main part of an elevator which is in operation using the elevator renewal method according to an embodiment of the present invention. Inside the elevator monitoring panel 3, there is a contact 4 for generating a control operation command signal, and this control operation command signal is incorporated in the control panel 1 after renewal. That is, the control operation interface relay 5 for performing the control operation of the renewed elevator group is connected between the DC power supply lines P and N, and the contact 4 is connected in series with the control operation interface relay 5. In the control panel 1 after the renewal, there is a normally open contact 5a of the control operation interface relay 5 connected to the DC power line P, and the control operation relay 6 in the control panel 2 before the renewal is connected via the connection line 8. Is connected to the DC power supply line N via.

In the elevator under renewal,
The elevator group controlled by the control panel 1 after the renewal and the elevator group controlled by the control panel 2 before the renewal are placed side by side. In this case, both the pre-renewal elevator and the post-renewal elevator must be operated for control operation.

Even if both the elevator before renewal and the elevator after renewal are provided side by side, the control operation can be performed by one control operation command signal by using the circuit configuration as described above. That is, assuming that the contact 4 for generating the control operation command signal of the elevator monitor panel 3 is now closed, the control operation command signal connects the control operation interface circuit 5 between the DC power supply lines P and N. , DC power supply line P ... Contact 4 ... Control operation interface circuit 5 ... The control operation interface relay 5 is energized by the circuit of the DC power supply line N. As a result, a control operation start signal is given and the elevator after renewal enters control operation. Further, when the control operation interface relay 5 is energized, the normally open contact 5a thereof is turned on, and this control operation start signal is taken into the control panel 2 before renewal by the connecting line 8 and thereby the control panel 2 before renewal. Before the renewal, a circuit of DC power supply line P ... Contact 5a ... Control operation relay 6 ... DC power supply line N is formed to energize the control operation relay 6 and a control operation start signal is given. Elevator goes into control operation.

In this way, 1 from the elevator monitoring panel 3
With one control operation command signal, the elevator before renewal and the elevator after renewal can be controlled. After that, when the renewal work progresses and all the pre-renewal elevators are replaced with the post-renewal elevators, the control panel 2 before the renewal will be removed, but at this time, it is sufficient to disconnect the connection line 8. , There is no need to make any special changes to the control panel 1 after renewal.

In the above embodiment, the control operation interface relay 5 is provided in the elevator control panel 1 after the renewal, and the control operation interface relay 5 is provided.
Although the control operation relay 6 in the elevator control panel 2 before the renewal is energized via the, the control operation start signal is first given to the elevator group after the renewal, and the elevator control panel 2 in the pre-renewal operation is controlled. Other circuit configurations may be used as long as the control operation circuit for energizing the control operation relay 6 is included.

[0012]

As described above, in the elevator renewal method according to the present invention, the control operation command signal is first input to the control operation circuit provided in the elevator control panel after the renewal, and then this control operation circuit is provided. Since both elevator control boards were connected to supply the control operation command signal to the elevator control board before renewal via
In order to remove the elevator control panel before renewal,
Even if the connection line connecting the elevator control panel after the renewal is disconnected, the control operation of the elevator control panel after the renewal is not affected, and the renewal work can be facilitated.
