Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator operating system, and more particularly to an elevator operating system suitable for operating an elevator in response to a hall call even if a hall call registration circuit fails.

Conventional elevators have had the disadvantage that if the hall call l1lf & circuit fails, the hall call becomes invalid until the failure of the hall call registration circuit is repaired, and one passenger cannot call for an elevator.

The present invention has been made in view of the above, and an object of the present invention is to provide an elevator operating device that can operate an elevator in response to a hall call even if the hall call registration circuit fails. .

A feature of the present invention is that the hall call registration circuit is configured to include switching means for connecting the circuit of the hall call button from the hall call registration circuit to the call registration circuit when it is detected that the hall call registration circuit has failed.

The present invention will be explained in detail below using the embodiments shown in FIGS. 1 and 2.

FIG. 1 and FIG. 2 are circuit diagrams showing an embodiment of a portion related to the present invention of an elevator operating system according to the present invention. 1st
In the figure, uJjJ(N-t)U are 1-(N
-1) Floor hall rise call button.

2D and #D are the hall down call buttons for floors 2 to N, respectively.
C8 is a hall call registration circuit, S is a hall call registration circuit H
When C8 fails, it is a failure detection relay that detects it and turns it off.S and S are transfer contacts of relay S, respectively, and P□ and N□ are DC power supplies, which are connected as shown in the figure. Also.

In FIG. 2, 1c and NC are car destination call buttons for floors 1 to N, respectively, and KC8 is a car call registration circuit.

S, is the normally closed contact of the failure detection relay S in Figure 1, RL is the failure indicator lamp of the hall call registration circuit, A to G are the symbols indicating that they are connected to A and G in Figure 1, respectively, and P ,,
N is a DC power supply, and these are connected as shown.

Next, the operation will be explained. In FIG. 1, if the hall call registration circuit HC8 is normal, the failure detection relay S is on, and each transfer contact S of the relay S is turned on. The normally open contact is closed, and the normally closed contact is closed.

Since the circuit is open, each hall call button IU ~ (N-1
)U, 20~ND circuits are connected to hall call registration circuit HC8, and each hall call button IU~(N-1)U
, 2D, and HD are not connected to the inverter circuit KC8 in FIG. 2, so they operate normally. Also,
Since the normally closed contact Sb of the relay S in FIG. 2 is open, the failure indicator lamp RL is off.

However, if the hall call registration circuit HC8 fails, the failure detection relay S turns off, so the hall call registration circuit HC8
8 is faulty, each transfer contact S of relay S. The normally open contacts are open, and the normally closed contacts are closed, and the circuits for each hall call button IU to (N-1)U, 2D, and HD are transferred from the hall call registration circuit HC8 to the call registration circuit KC8 in Figure 2. The car call registration circuit KC8 is connected to each car call button 1c, NC and each hall call button IU to (N
-1) Circuits U and 2D to ND are connected in parallel. Therefore, when any hall call button is pressed, it is registered in the hall call registration circuit KC8, and one passenger can call an elevator, thereby improving the per-passenger service. Further, since the normally closed contact Sb in FIG. 2 is closed, the failure indicator lamp RL lights up, thereby calling attention to the situation.

As explained above, according to the present invention, even if the hall call registration circuit fails, the elevator can be operated in response to a hall call, and the serviceability for passengers can be improved.
