Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention regulates elevator call registration, particularly for registering calls to floors that are used only by specific people, or The present invention relates to a call registration method suitable for cases where an elevator is to be used immediately.

[Conventional technology]

Conventional methods for priority registration of call registration to specific persons required devices to be carried around with special tools such as key switches and magnetic cards.

Furthermore, as described in Japanese Patent Laid-Open No. 56-165669, a display device that constantly displays the destination floor even when the elevator is not in use results in unnecessary operation and power consumption, and furthermore, registration The structure made it impossible to distinguish whether button operations were made by a prank or by an authorized person.

[Problem that the invention seeks to solve]

In order to eliminate the magnetic card key switch that is the conventional method for regulating call registration, it is possible to register calls by repeatedly operating the operation button for code registration, and
In order to prevent abuse due to mischief, etc., the display device is configured to turn off and stop functioning if the repeated operation of the operation button is not completed within a certain period or if the same operation differs from the predetermined pattern. .

When the code registration operation is not performed, the display device is turned off and the function is stopped after a certain period from the last operation, and the activation method is started by operating the operation button.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator call registration method that does not use special tools, is difficult to detect by third parties, and consumes low power.

[Means for solving problems]

The above purpose is to install a display device that sequentially displays coded numbers in halls and cars, in addition to a general call registration device, and a registration button that allows you to register the displayed next floor by pressing in a predetermined pattern. This is achieved by installing

[Effect]

The display device, which is a coded call registration device provided separately from the hall button or the car button, and which sequentially displays destination floors, repeats displaying coded numbers at regular intervals.

If a registration button is pressed in a predetermined pressing pattern while a certain dark display is displayed, a call can be registered.

The press pattern can be made difficult for a third party to easily understand by combining coded numbers, and if the operation is performed incorrectly, the device will not operate, and even if the operation is not completed within a certain period. Since it is the same, it is perfect as an encrypted call registration device.

Due to the first operation of W, contact 8 CR1 is closed, relay SR is closed, contact SRz is closed, and contact O
Since Tx~9Tz are closed, the STR relay is closed, contact STR1 is closed, and it becomes self-holding.Primary contact 8CRx in Fig. 4 is closed, contact 5TR4 is closed, and contact ITg Since the circuit is closed, the OT timer operates, and one second later, the contact OT4 closes and holds itself, the contact OTz shown in FIG. 1 closes, and "0" is displayed on the table closing device ILM.

Then, the contact OTa of the OT timer in Fig. 4 closes,
Contact 2Te closes, the IT timer operates, and 1 second later, the contact ITe closes and the OT timer is released.
Contact OTz in FIG. 1 is opened and the "0" display disappears, and contact ITz is closed and "1" is displayed.

Below, "1" → "2" → "3"... "9" → "
To display "O", the same operation is repeated and a digital sequential display is performed.

The numbers displayed by the digital display device shall indicate the codes for encrypted call registration, r3'', rQ''.

Assuming that you operate the button switches in order when each display of "4" is displayed, first, if you press the button switch SW in Figure 2 at the first display of [3], SRz will close, 5TRs is closed, 15RA relay is closed, 15RAz is closed and self-holding.

In FIG. 3, ISRAs is closed, 2SRAa is closed, 3T4 is closed, and OUTx is closed, so the IY relay is turned on and IYz is closed and self-holding. When SW is released, l5RAz in Figure 2 is closed, SRa is closed, 13RB relay is closed, and l5RB is closed.
z closes and maintains itself.

Next, when "8" is displayed for the second time, press the SW shown in Figure 2.
15RBz is closed, SR4 is closed, 2SRA
The relay closes, 2SRAz closes, and maintains itself. In FIG. 3, 2SRA4 is closed, 3SRAz is closed, 8T4 is closed, and OUT z is closed, so the 2Y relay is closed, and 2Y1 is closed and self-holding. If you release SW.

2SRAz in FIG. 2 is closed, 5RIs is closed, 2SRB relay is turned on, and 2SRB1 is closed and self-holding.

Next, when "4" is displayed for the third time, press the SW in Figure 2 to display 2.
SRBz is closed, SRs is closed, 3SRA relay is turned on, 3SRA is closed and self-holding.
