Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for registering elevator calls.

Elevator operation is performed by an up call button, a down call button, and a destination floor call button installed in the car, which are installed at the landing of each floor, and a registration relay is activated by the operation of the above-mentioned call button, and the memory circuit for the above-mentioned call is activated. The storage circuit continues to operate the elevator.

However, it is not known whether the registration relay will operate normally due to the operation of the above button until the above button is operated, and if the call cannot be registered despite the operation of the above button, Passengers will feel uncomfortable.

Therefore, in the past, an inspection circuit was provided separately from the call registration circuit.

A conventional example will be explained below with reference to FIG. In the figure,
(+) and (-) are DC power supplies, 1 to 4 are destination floor buttons for the 1st to 4th floors provided inside the car, 1A to 4A are car call registration relays for the 1st to 4th floors, 1Aa, 1
Ab~4Aa, 4Ab are normally open contacts, 1B~4B are car position contacts that open when the car is on the 1st to 4th floors, 1C~4C are backflow blocking diodes, 5 is an operation indicator, and 6 is an attached This is an inspection time relay that operates immediately when it is energized and returns after a certain period of time when it is de-energized. 6a is its normally closed contact, and 7 is an inspection switch.

That is, for example, if destination floor button 1 on the 1st floor is operated, (+)-6a-1-1B-1A-
The car call registration relay 1A on the first floor is energized by the (-) circuit and self-maintained by closing the contact 1Aa. At this time, the circuit to the operation indicator lamp 5 is opened by the backflow blocking diode 1C.
Thereafter, the car runs according to a well-known operation circuit (not shown), and when it arrives at the first floor to respond to the call from the first floor, the car position contact 1B on the first floor is opened and the car position contact 1B is opened.
The car call registration relay 1 on the floor is deenergized and this operation ends. Thereafter, the operation will continue as long as there is a call, as described above.

Now, when there are no passengers such as when the operation is suspended or at night,
Assuming that inspection switch 7 is closed, (+)-7
-6-(-) circuit operates the time relay 6 and opens the contact 6a. This opens the self-holding circuits of the car call registration relays 1A to 4A on the destination floors of the 1st to 4th floors, while (+)-7-1C to 4C-
The car call registration relays 1A to 4A on the first to fourth floors are energized by the circuits 1A to 4A-(-). At this time, car call registration relay 1A on the 1st floor to 4th floor
If 4A operates normally, contacts 1Ab to 4Ab are closed and (+)-7-1Ab-2Ab-3Ab-4Ab-
The operation indicator light 5 is turned on by the circuit 5-(-), confirming that it is normal. At this time, 1
If any one of the car call registration relays 1A to 4A on the floors to the fourth floor is not normal, the operation indicator light 5 will not light up, indicating that there is an abnormality.

When the inspection is completed and the inspection switch 7 is opened, the time relay 6 is deenergized and the contact 6a is closed after a certain period of time. This prevents the car call registration relays 1A to 4A from being self-held.
This will return to normal.

Figure 2 shows another conventional example, which is applied to a car call registration circuit for an elevator that stops on the 29th floor.

In the figure, 1Ab to 29Ab are car call registration relays (not shown) on the 1st to 29th floors that are normally open, as can be easily understood from the car call registration relays 1A to 4A on the 1st to 4th floors in Figure 1. Contact, 1C to 29C
is also a backflow blocking diode, 7 is terminal a~
It is a 4-point inspection switch with c and (OFF). The rest is the same as in FIG.

First, when you turn the inspection switch 7 to terminal a,
(+)-7-1C-9C-1A-9A-(-) circuit, car call registration relay 1A for 1st to 9th floors
~9A is energized, contacts 1Ab~9Ab are closed,
If the operation indicator light 5 lights up, it is confirmed that the operation is normal. Next, if you flip switch 7 to terminal b, 10
If the car call registration relays 10A to 19A on the floors to the 19th floor are energized and the operation indicator light 5 lights up through the contacts 10Ab to 19Ab, it is confirmed that the car is normal. A similar result is obtained when the switch 7 is turned to the terminal c side.

In the conventional example shown in FIG. 1, all car call registration relays 1A to 4A are inspected at the same time.
In this conventional example, this is divided into a plurality of groups for inspection. This allows easy inspection even when there is not enough DC power supply (+) and (-) due to a large number of stops.

However, in the past, it was not possible to identify which call registration relay had failed, and it took a long time to resolve the problem.

Furthermore, if all of the call registration relays were provided with display lamps, the number of display lamps would increase, resulting in an increase in cost.

This invention was made to solve the above-mentioned problem, and relates to an elevator call registration device that can identify a failed call registration relay using fewer lamps than the number of call registration relays.

FIG. 3 shows an embodiment of this invention.

In the diagram, 5-0 is the 0th position operation indicator light, 5-1 to 5-
9 is the 1st to 9th position operation indicator light, 5-10 is respectively
The 10th place is the operation indicator light, and 5-20 is the 20th place operation indicator light. Others are the same as in FIG. 2.

For example, if you turn switch 7 to side b, floors 10 to 19
The floor car call registration relays 10A to 19A are energized, and the contacts 10Ab, 10Ac, 11Ab, 11Ac to
19Ab and 19Ac are closed and the 0th, 1st to 9th and 10th position operation indicator lights 5-0, 5-1 to 5-9, 5
-10 lights up, 10th floor car call registration relay 1
It is confirmed that 0A to 19A are normal. If the car call registration relay 11A on the 11th floor is abnormal, the contacts 11Ab and 11Ac will not close, so the 1st operation indicator light 5-1 will not light up (10
The operation indicator light 5-10 lights up when the contact 10Ac is closed. ). This makes it easy to confirm that the car call registration relay 11A on the 11th floor is abnormal.

In the embodiment, the explanation was given using the destination floor button in the car, but it goes without saying that the present invention can also be applied to the up call button and down call button at the landing on each floor.

Also, switch 7 is turned on to operate the inspection circuit.
However, the inspection circuit may be automatically operated by detecting that the vehicle is not used by passengers, such as at night or when the vehicle is not operating.

As explained above, in this invention, the call registration relays are divided into multiple groups, the call registration relays are energized for each group, and the operating status of the call registration relays for each group is individually displayed. , an inoperable call registration relay can be identified by a display having a group of display parts, and an inexpensive elevator call registration device can be obtained.
