Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a call registration device that allows the use of an elevator to be performed by both specific persons and unspecified persons.

[Background of the invention]

BACKGROUND ART Recently, whereas conventionally elevators could be freely used by unspecified people, there has been an increasing demand for elevators to be restricted to specific people.

On the other hand, initially we had considered that only certain people could use the elevator, but if the tenant changed and the building became exclusive to one company, we might have to change the elevator so that they could use it freely. In other words, if a system is to be adopted in which it is possible to ring a bell by special operation, it is desirable to have a system that can be used for different purposes with a simple switch that can be used freely by unspecified persons.

[Summary of the invention]

In the present invention, a plurality of buttons are provided on the operation panel for call registration, and when another button is operated in a predetermined manner while a predetermined specific button is being pressed, the specific button is pressed. Calls can be registered, while a switch box installed somewhere else, for example, at the bottom of the call registration operation panel.
By operating a switch installed inside the vehicle, a destination call can be registered without pressing the specific button mentioned above.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows some of the operation buttons of an in-car operation panel (hereinafter referred to as OPB) for call registration, and a switch box 12 containing a switch 13 for switching between special operation and normal operation. In the figure, 1 to 4 indicate destination buttons from 11@ to the 4th floor, and A and B indicate buttons for operating codes. Second
Diagrams are made using the buttons above. 1 shows the configuration of the decryption circuit of the present invention and the circuit that separates it. In this embodiment, the destination floor button is used as a specific button, and the button A
.

B all the prescribed steps (here, press button A, then press B
). In addition, this encryption method works only when the switch SW is pushed to the (1) side, and when it is pushed to the (2) side, it works like the normal OPB destination button. Call registration is possible by pressing the button 4. In addition, relay coils IB to 4B are energized and turned on when buttons 1 to 4 are pressed for each destination floor, and AB and BB are relays that are energized and turned on when valley buttons A and B are pressed. , I
BI, 2B1 to 4B1, and 4B2 are relays 1 that are excited and turned on when the circuit conditions shown in the figure are satisfied. The circuit for registering a call using the contacts of the relays IB2-4B2 is the same as the conventional circuit.

The circuit operation when the switch SW is set to the (1) side and the cryptographic registration method is used will be explained. Specific?
As part II, an explanation will be given taking as an example the case of making a call for the first floor. Press destination floor button 1.

This turns on relay IB and closes its contact IBI. When button A is pressed in this state, relay AB is turned on and its contact ABI is closed.

Since button B is not pressed at this time, relay BB is set to 0.
It is FF, and its contact B B 1 is also closed.

Therefore, the relay IBO is (JF'P L).

Therefore, due to IBO,→B BI-+A B, relay IB1 is ONL, and its contact IBI is ONL, self-holding. Next, when button A is released and button B is pressed, relay BB is ONL and its contact 13B2 is closed.Also, since relay IBI is self-holding, contact 1B12 is closed, and relay AB is closed when button A is removed. O when released
FF! Therefore, contact AB is closed. Therefore, relay IBZ becomes ONL due to IB12→AB2→HB2, and its contact IB2I closes, causing relay IB2 to hold itself. In this way, when destination button 1 is pressed, button A is pressed, and then button Bk is pressed, relay IB2 is turned on.

As is clear from the circuit, when destination button 1e is released during the operation of buttons A and B, relays IBI, 1B2 (JFF
1B20''iON even if you press buttons A and B.
do not. Also, if you press button B first without pressing button 8 after pressing destination button 1, contact Hl (1 closes, so relay IBO turns on and holds itself, and contact IB0
1 will end, so how do I press buttons A and B after that?
Relay IB2 does not turn on even if I try to operate it. here,
If you register the call on the first floor using the IB2 contact point, you can register the call using code. With this kind of times wr configuration, SW is set to (2
) side, press destination button 1 to turn relay IB on.
NL contact IB3 is closed, relay IB2 is immediately turned on, and call registration is possible. In other words, the encryption registration method is switch 1
By switching the , the same call registration as before is possible. Here, this switch St to i may be housed in a conventional switch box at the bottom of the OPB. This switch box is generally equipped with a lock, so it may not be operated accidentally.
It will not be misused.

The present invention can also be used for hall calling devices and elevators that utilize microcomputers.

〔Effect of the invention〕

According to the present invention, in the call registration of the encryption method, the encryption method can be canceled when the user changes, and the maintenance person can easily cancel the encryption method and perform maintenance work speedily. become.
