Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for notifying a hall of elevator car assignments.

In elevator group management operation based on the assignment method, when a hall call is registered, the car most suitable for responding to this call is assigned.

The assigned light (usually also serves as the arrival forecast light) of the hall where the hall call occurred.

) is lit, and an alarm such as a chime or gong is sounded once to notify the boarding area.

When it is determined that the assigned car will arrive at that floor, the above arrival warning light will flash and the alarm will be activated multiple times (
Usually, a double tone (high and low) sounds once) to notify the arrival of a car.

In this way, by notifying the car assignment and car arrival, the passengers waiting at the landing can know which car will respond, and can smoothly prepare for boarding.

However, if both an inbound call and an outbound call are registered at a certain floor, and the car assignments for these calls are made at short intervals, the alarm at that hall will emit two consecutive tones. Passengers waiting at the landing may mistake this for the double beep that is emitted when a car arrives.

This invention aims to improve the above-mentioned problems, and provides an elevator landing notification device that eliminates the possibility of confusing the notification sound for the arrival of a car even when the notification sound at the time of car assignment is emitted continuously. The purpose is to provide.

An embodiment in which the present invention is applied to a fifth floor landing will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is the up call assignment signal (Fig. 2a) that becomes "1" when Car 1 is assigned to an up call on the 5th floor landing, and becomes "0" when it responds to this call (Fig. 2 a), and 2 is also the down call assignment signal. The call assignment signal (Figure 2c), 3°4, outputs 3a, 4 for a certain period of time (for example, 2 seconds) when the input becomes 11''.
A one-shot multivibrator (hereinafter referred to as OM) in which a is "1" (see Fig. 2).

d), 5 is an OR gate, and 5a is its output (Fig. 2 e)
, 6 is an alarm such as a chime or gong installed in the landing of car No. 1 on the 5th floor. It emits a single sound only when the input becomes "1", and even if the input remains "1" thereafter, it will emit a sound again. It is constructed so that it does not emit any sound.

Now, suppose that an inbound call and a downbound call at the landing are registered on the 5th floor, and car No. 1 is assigned to that inbound call. When the upbound call is assigned, signal 1 becomes "1" and at 0M3, output 3a is "1" for 2 seconds. Become.

This output 3a is applied to the annunciator 6 through the OR gate 5, and the annunciator 6 emits a single tone.

Next, when the down call is also assigned to the first car within 2 seconds after the up call is assigned, the down call assignment signal 2 becomes "1", and the output 4a of 0M4 becomes "1" for 2 seconds.

However, the output 5a of the OR gate 5 has already become "moon", and the alarm 6 no longer emits any sound.

When the output 4a of 0M4 becomes "0", the input of the alarm 6 also becomes "0".

That is, even if car No. 1 is assigned an up call and a down call within a short period of time, the alarm 6 only emits a single tone, thereby eliminating the possibility of mistaking it for the arrival of a car.

FIG. 3 shows another embodiment of the invention.

In the figure, 7 and 8 are AND gates, and 9 and 10 are set when the S terminal input is "month" and this is memorized, the output from the Q terminal becomes "1", and the input to the R terminal becomes "0". '', the memory circuit is reset and the output from the Q terminal becomes ``0'' even if the input to the S terminal is ``moon.'' 11 is an OML set to output for about 1 second. 12 is a NOR gate.

If both assignment signals 1 and 2 are (1), then OR
The output 5a of the gate 5 is "0", and the output of the NOR gate 12 is "the moon".

Here, when the upstream call assignment signal 1 becomes "1", the AN
The DNO gate output becomes "1" and the memory circuit 9 is set.

Due to the output of this memory circuit 9, the output 5a of the OR gate 5 becomes "1" as in FIG. 1, and the output of 0M11 also becomes "1".
” and the alarm 6 emits a single tone.

Further, when the output 5a becomes "1", the output of the NOR gate 12 becomes "0", and the ANDNO gate is closed for 2 seconds.

Therefore, within two seconds after the assignment signal 1 becomes "1", the assignment signal 2 becomes "1", the output of the ζAND gate 8 is "0", and the memory circuit 10 is not set.

Output 3a of 0M3 says ``When 2 seconds have passed since the moon turned,
The output 3a becomes ``0'', the output of the NOR gate 12 becomes ``1'', and the output of the AND gate 8 becomes ``1''. 4a becomes "1".

As a result, the annunciator 6 emits a single tone via the OR gate 5 and the OMl 1.

When the first car responds to the up call and down call from the fifth floor, the assignment signals 1 and 2 become "0" and the memory circuits 9 and 10 are reset.

In this way, even if an assignment sound is issued for an uplink call and then assigned to a downlink call within a short time, the assignment sound will not be issued immediately, but will be issued after a certain period of time has elapsed.
There is no need to worry about mistaking it for the arrival sound.

Note that the circuits shown in FIGS. 1 and 3 are similarly provided for other machines.

4 and 5 show other embodiments of the invention, 1
The operations of the No. 1 or No. 2 car influence each other.

FIG. 4 is almost the same as the configuration for two machines shown in FIG. 3, and the numbers with A at the end are for the first machine, and those with B are for the second machine.

The operation is almost the same as that shown in Fig. 3, and the uplink call interference 1 assignment signal 1A of the No. 1 machine or the uplink call assignment signal 1B of the No. 2 machine
When any one of them becomes "1", the output of the NOR gate 12 becomes "0", and the output of the ANDNO gate becomes "0".

8A, 7B, and 8B are all closed, and only the alarm 6A of the first car or the alarm 6B of the second car emits a single tone.

That is, within a certain period of time after the allocation signals 1A and 1B become "1", when the allocation signal 2A or 2B becomes "month", the allocation sound will be heard from either of the annunciators 6A or 6B after a certain period of delay. Emitted.

In Figure 5, 13A, 14A, 13B, 14B are 0.1
This is an OM that is set to output for a short period of time, about seconds.

The rest is the same as in FIG. 4.

When the uplink call assignment signal of No. 1 becomes "1", the signal becomes 0.
The output of M13A is "1" for 0.1 seconds, and the output of 0M3A is "1" for 2 seconds.

Therefore, ANDNO Gatef A8A, 7B, 8
B is closed for 2 seconds.

During this time, for example, the down call assignment signal 2B of the second machine is 1.
1”, 0M14B output is “1” for 0.1 seconds.
'', the output of the AND game 1-8B remains at ``0'' and the memory circuit 10B is not set.

In the end, the alarm 6A only emits a single sound.

The other assignment signals can be explained in the same way, and it can be easily implemented in the case of two or more units.

Each of the above embodiments has been described on the assumption that the up call and down call assignment signals are generated within a certain period of time.

However, when a landing on a particular floor is crowded, multiple cars may be assigned to a landing call in the same direction.

At this time, hall calls in the same direction may occur within a certain period of time, and it goes without saying that the present invention can be applied to this case as well.

As explained above, in this invention, even if another assignment signal is input within a certain time after a car assignment signal is issued, the assignment sound according to the previous assignment signal is only emitted, and other Since the generation of the assigned sound was prevented,
Since the allocated sound is not emitted continuously, it is possible to eliminate the possibility that passengers waiting at the landing may mistake it for an arrival sound.
